Poultry feeder
A feeder assembly for feeding birds of all kinds is provided in three separate embodiments. The feeder assembly of each embodiment is configured to provide for the welfare of birds as they feed from the feeder assembly by allowing the birds' breasts to conform to a rim member of the feeder assembly. The feeder assembly of two embodiments also provides for a lower feed gate to provide feed into a pan member of the feeder assembly. The lower feed gate is always open and can be raised or lowered as desired. The feeder assembly of one of the embodiments also provides for an upper feed gate to provide feed into the pan member of the feeder assembly. The upper feed gate can be opened or closed, and, when open, can adjust the height at which feed flows through the upper feed gate.

No. 10/455,054, filed on Jun. 5, 2003, and entitled “Poultry Feeder” which, in turn, claims the benefit of domestic priority of U.S. Provisional Application Ser. No. 60/391,731, filed Jun. 26, 2002, and entitled “Poultry Feeder”.
BACKGROUND OF THE INVENTIONThe invention relates to animal feeding systems and, more particularly, relates to feeder assemblies for poultry and the like.
Automated feeding systems for poultry and like domestic animals have proved highly successful in modern animal husbandry operations. These systems can supply feed mixtures to a large poultry flock with minimum effort by the poultry grower. Both the amounts of feed delivered and the proportions of feed ingredients can be regulated, thus permitting the flock to be inexpensively raised from chicks to mature, commercially valuable birds in a relatively short time.
Among the important parts of such automated feeding systems are the feeder assemblies. These assemblies receive feed flow from a feed conveyor, and are located on or near the poultry house floor to afford the birds ready access to the feed. Among the patents disclosing such feeder assemblies are, for example, U.S. Pat. Nos. 3,388,690, 3,511,215, 3,811,412, 3,911,868, 4,070,990, 4,476,811, 4,834,026, 4,995,343, 5,092,274, 5,941,193 and 6,173,676.
Early poultry growers traditionally introduced very young birds into poultry houses and provided supplemental feed to the young birds or chicks on paper, cardboard or the like, which was laid on the poultry house floor. The chicks were not initially introduced to feeding from feeder assemblies for two main reasons. One reason was that chicks were unable to gain access to the feed in the feeder assemblies because the height of the feeder assemblies from where the birds would gain access to the feed was too high for the chicks. Another reason was that the feed which was introduced into the feeder assembly was always provided on the bottom of a pan of the feeder assembly such that even if the young birds could reach over the height of the side of the feeder assembly, the birds could not then reach down to eat the feed at the bottom of the feeder assembly. Thus, the poultry grower provided supplemental feed to the chicks either by providing the supplemental feed to the chicks outside of the feeder assemblies or by hand filling the supplemental feed into the feeder assemblies to provide a high feed level.
Problems, however, arose with such practice. Among these problems, obviously, was that such a practice required more time and labor by the poultry grower which could be better utilized elsewhere. Also, the feed provided on the floor of the poultry house came into contact with waste, dirt, etc., which the birds would also then eat, potentially causing health problems for the birds. Further, the birds raked the feed with their feet such that the feed became spread out over the poultry house floor, such that a fair amount of the feed placed on the floor by the poultry grower was wasted.
Thus, many prior art feeders were designed to help combat these problems. For instance, the feeder assemblies disclosed in U.S. Pat. Nos. 5,311,839, 5,462,017 and 5,718,187 attempted to solve the problem of the height of the feeder assemblies being too high such that smaller birds could not gain access to or see the feed presented in the feeder assembly to eat it, thus requiring the poultry growers to either utilize the supplemental feed, as discussed above or provide separate feeder assemblies in which the smaller birds would be able to feed from. These feeder assemblies utilized a lost motion connection between the grill and the pan to provide both a shallow pan depth for younger, smaller birds and a deep pan depth for older, larger birds. The problem with the lost motion connection for the poultry grower is that in order to utilize the lost motion connection, the feeder assemblies had to be raised off of or lowered onto the poultry house floor. For instance, the feeder assemblies could not be lowered from the deep pan depth to the shallow pan depth without a bottom of the pan resting on the poultry house floor. As the floors of poultry houses are often uneven, the feeder assemblies could not all be consistently configured in the same manner when the feeder assemblies were positioned on the floor of the poultry house.
Other designs like the feeder assemblies disclosed in U.S. Pat. Nos. 4,476,811 and 5,092,274 also attempted to solve the problem of the feed being presented to younger, smaller birds at too low of a level within the feeder assemblies. The feeder assemblies provided both an upper or “brood” feed gate to provide high feed levels for younger, smaller birds and a lower feed gate to provide lower feed levels for older, larger birds. The upper feed gate was provided as a window in the feed drop tube of the feeder assembly, which, when open, would allow feed to flow therethrough to create a high feed level in the feeder assembly for the young birds to easily see and eat. When the birds grew older and larger, the poultry grower could close the upper feed gate and allow the feed to flow through the bottom of the feed drop tube, i.e., the lower feed gate, to provide a lower feed level.
These feeder assemblies, while highly successful in industry, do, however, have some disadvantages to them. For example, in these inventions, the upper and lower feed gates are typically not both able to be open if the poultry grower should so desire them to be. Also, the feed gates are typically only opened and closed by moving the feeder assemblies on and off of the ground. Finally, these feeder assemblies did not provide for a smooth transition from a high feed level to a low feed level; as a practical matter the poultry grower could only provide a high feed level or a low feed level, but nothing in between.
Feeder assemblies of the prior art have also caused other problems for the poultry grower. For example, when birds grow larger, the birds typically like to eat from the feeder assemblies by resting a front side of their bodies on or against the feeder assembly in some manner. As feeder assemblies of the prior art have not typically been designed with the comfort and health of the birds in mind, the birds tend to eat from the feeder assemblies while being uncomfortable. In many prior art feeder assemblies, when birds rest on or against the feeder assemblies, detrimental physical effects, such as bruising, blistering, irritation, etc., to the front sides of the bird's bodies, such as their breasts, may occur. Such detrimental physical effects can cause two major problems. One is that since the front sides of the birds' bodies will become detrimentally physically effected, the birds will not be comfortable resting on or against the feeder assemblies, such that the birds may not eat as much food from the feeder assemblies as it is too uncomfortable for them to do so. Thus, the birds either do not become as large and are not as commercially valuable as they could have been, or the rate at which the birds grow is reduced, thus taking longer for them to reach their optimal size and weight. Secondly, once the birds are defeathered and graded, if the front sides of bird's bodies are detrimentally physically effected, the birds will receive a lower grade, thus making them less commercially valuable.
Therefore, an improved feeder assembly is needed which will overcome the problems and disadvantages of prior art feeder assemblies. The present invention provides such a feeder assembly. Features and advantages of the present invention will become apparent upon a reading of the attached specification, in combination with a study of the drawings.

Briefly, and in accordance with the foregoing, the invention provides a feeder assembly which is adapted to be attached to a feed supply conduit of a feeder system. Three embodiments of the feeder assembly are provided.
The first embodiment of the feeder assembly generally includes a pan member, a grill member, an outer drop tube member, an inner drop tube member, and an inner drop tube actuator.
The outer drop tube member hangs from the feed supply conduit of the feeder system by a member which wraps around the feed supply conduit. The inner drop tube member is positioned within and supported by the outer drop tube member. Both the inner and outer drop tube members have windows or apertures therethrough. An extension of the inner drop tube member extends through an opening at a top of the outer drop tube member such that it can be connected to the inner drop tube actuator. When the inner drop tube actuator is moved, the inner drop tube member is rotated within the outer drop tube member such that an upper feed gate can be opened, by alignment of the windows, or closed, by disalignment of the windows.
The grill member is rotatably connected to the outer drop tube member by helical threads on both the grill member and the outer drop tube member, which allow a lower feed gate of the feeder assembly to be raised or lowered relative to the pan member.
A rim member of the grill member is connected to an upstanding outer portion of the pan member with an upstanding inner portion of the pan member extending within the inner drop tube member. The pan member has a base portion between the upstanding outer and inner portions for presenting feed. The upstanding inner portion of the pan member helps promote high feed levels out of the upper feed gate.
The outer drop tube member has wing portions extending from a bottom thereof which can be positioned above the base portion of the pan member to ensure that the lower feed gate of the feeder assembly is always partially open such that some feed can flow therethrough.
The grill member is configured such that birds which lean on or against the rim and spoke members of the grill member to eat feed presented in the pan member will not be detrimentally physically effected, or the detrimental physical effects will, at a minimum, be decreased. The birds will also be comfortable leaning against the rim and spoke members such that feeding is promoted.
The rim member of the grill member also is configured such that a shallow pan depth is provided for smaller birds while a deep pan depth is provided for larger birds. The shallow and deep pan depths are provided without the need to adjust any portion of the feeder assembly.
The second embodiment of the feeder assembly removes the inner drop tube member and the inner drop tube actuator, and removes the windows from the outer drop tube member such that feed supplied to the feeder assembly is forced to flow through only the lower feed gate.
The third embodiment of the feeder assembly removes the grill member such that only the pan member is provided, with the pan member being configured similar to the rim member of the grill member in the first and second embodiments of the feeder assembly, such that when birds which lean on or against the pan member to eat feed presented therein will not be detrimentally physically effected.

The purpose of the grooves 266 will be discussed with more detail herein.
The cylindrical portion 254 has a helical thread 268 winding inwardly around the aperture wall 260. The helical thread 268 begins at one of the grooves 266 proximate to the top end 262 of the cylindrical portion 254 and winds around the aperture wall 260 until it returns to the groove 266 at which it started. The helical thread 268 ends at a position which is approximately midway between the top end 262 and the bottom end 264 of the cylindrical portion 254. The helical thread 268 is cut away at the grooves 266 such that the helical thread 268 is only preferably provided along the aperture wall 260 where the grooves 266 are not provided. The purpose of the helical thread 268 will be discussed with more detail herein.
The extension member 256 curves downwardly and outwardly from the top end 262 of the cylindrical portion 254. The extension member 256 preferably has a first portion 270, a second portion 272 and a third portion 274. The first portion 270 of the extension member 256 curves downwardly and outwardly from the top end 262 of the cylindrical portion 254 such that a top surface 276 thereof is convex. The second portion 272 of the extension member 256 curves downwardly and outwardly from the first portion 270 of the extension member 256 such that a top surface 278 thereof is concave. The third portion 274 of the extension member 256 extends downwardly from the second portion 272 of the extension member 256 and is parallel to the cylindrical portion 254. The fifth portion 252 of each of the spoke members 156 connects to the extension member 256 with the first leg 226 being connected to the third portion 274 and the second leg 228 being connected to the extension member 256 at the connection of the second portion 272 and the third portion 274.
The top surface 276 of the first portion 270 and the top end 262 of the cylindrical portion 254 can also have a plurality of indicators 280 placed thereon. In a preferred embodiment, the indicators 280 number six (6) and are positioned equidistantly around the top surface 276 of the first portion 270 and the top end 262 of the cylindrical portion 254 such that they are spaced sixty (60) degrees apart.

The inner drop tube member 110 further includes a plurality of openings 396. The openings 396 are cut out from portions of the first and second portions 378, 380 of the member 374. Each opening 396 is defined by a top edge 398, which is a bottom edge of the third portion 382 to which the second portion 380 would connect to the third portion 382. Each opening 396 is further defined by a first side edge 400 and a second side edge 402. The first side edge 400 extends downwardly from one end of the top edge 398 along the entire second portion 380 and along the entire first portion 378 to the bottom end 390.of the member 374. Similarly, the second side edge 402 extends downwardly from the other end of the top edge 398 along the entire second portion 380 and along the entire first portion 378 to the bottom end 390 of the member 374. Thus, each opening 396 is open at the bottom end 390 of the member 374, such that the openings 396 are not bounded by a bottom edge.
For each opening 396 provided in the inner drop tube member 110, the inner drop tube member 110 further includes first and second protrusions 404, 406 which extend outwardly from the first portion 378 of the member 374.

The second protrusion 406 has an inner edge (not shown), an outer edge 416, a top edge 418, and a bottom edge 420. The inner edge of the second protrusion 406 is positioned along the entire length of the first portion 378 of the member 374 along the second side edge 402. The top edge 418 extends angularly downwardly and outwardly to the outer edge 416 from a top of the inner edge, which is provided at the connection of the first portion 378 to the second portion 380. The bottom edge 420 extends angularly downwardly and outwardly to the outer edge 416 from a bottom of the inner edge, which is provided at the bottom end 390 of the member 374. The outer edge 416, thus, extends from between the top and bottom edges 418, 420. Thus, the second protrusion 406 extends below the bottom end 390 of the member 374. The second protrusion 406 further includes a lip portion 422 which extends outwardly from the outer edge 416 of the second protrusion 406 proximate to the junction of the outer edge 416 and the bottom edge 420.

The inner edge of the third protrusion 436 is positioned against the first portion 378 and extends from the bottom end 390 of the member 374 approximately one-third of the distance as does the first and second protrusions 404, 406. The top edge 440 extends angularly downwardly and outwardly to the outer edge 438 from a top of the inner edge. The bottom edge 442 extends angularly downwardly and outwardly to the outer edge 438 from a bottom of the inner edge, which is provided at the bottom end 390 of the member 374. The outer edge 438, thus, extends from between the top and bottom edges 440, 442. Thus, the third protrusion 436 extends below the bottom end 390 of the member 374. The third protrusion 436 further includes a lip portion 444 which extends outwardly from the outer edge 438 of the third protrusion 436 proximate to the junction of the outer edge 438 and the bottom edge 442. The lip member 444 is connected to the ring member 424 at the inner surface thereof.

In a preferred embodiment, the plurality of protrusions 448 number two (2) and are positioned equidistantly from one another such that they are positioned one-hundred eighty (180) degrees from one another. Preferably, the protrusions 448 extend the entire height of the fifth portion 386 from the fourth portion 384 to the top end 392 of the member 374. Each of the protrusions 448 are preferably not in vertical alignment with any of the windows 434. The protrusions 448 help to keep the inner drop tube member 110 centered within the outer drop tube member 108, and also creates a gap between the inner drop tube member 110 and the outer drop tube member 108 in order to prevent a buildup of feed or dust between the inner drop tube member 110 and the outer drop tube member 108 which would hinder rotation of the inner drop tube member 110 relative to the outer drop tube member 108. The cavities 446 are provided because of the formation of the protrusions 448.
The inner drop tube member 110 further preferably includes a plurality of slots 450 therethrough. Each slot 450 is generally vertical and extends through the second portion 380 of the member 374, and cuts through the third portion 382 and a portion of the fourth portion 384. In a preferred embodiment, the plurality of slots 450 number four (4) such that they are separated from one another by ninety (90) degrees. Each slot 450 is preferably situated between two (2) of the windows 434. The slots 450 allow feed or dust in the gap between the inner and outer drop tube members 110, 108 to fall through the inner drop tube member 110 and into the pan member 104.
The inner drop tube member 110 further includes an extension member 451 which extends upwardly from one of the protrusions 448 which extends to the top end 392 of the member 374.

Operation of the Feeder Assembly 100 Assembly of the Feeder Assembly 100 In order to utilize the feeder assembly 100, the parts of the feeder assembly 100 must first be assembled to that as best illustrated in
The inner drop tube member 110 is positioned within the aperture 284 of the member 282 of the outer drop tube member 108 with the bottom surface 432 of the ring member 424 of the inner drop tube member 110 being positioned on the ledges 328 of the outer drop tube member 108. The fifth portion 386 of the inner drop tube member 110 is positioned around the inner cylindrical portion 344 of the outer drop tube member 108.
The conduit acceptor member 348 of the outer drop tube member 108 is positioned around the feed supply conduit 102 with an opening (not shown) in the feed supply conduit 102 being in communication with the apertures 282, 346, of the outer drop tube member 108.
When the inner drop tube actuator 112a is utilized (see
When the inner drop tube actuator 112b is utilized (see
When the inner drop tube actuator 112c is utilized (see
The grill member 106 is positioned around, and connected to, the outer drop tube member 108. The helical thread 268 of the grill member 106 is positioned between the helical threads 330, 332 of the outer drop tube member 108 such that the grill member 106 can be rotatably moved relative to the outer drop tube member 108. The protrusions 340 on the outer drop tube member 108 are temporarily locked into position within the grooves 266 of the grill member 106.
The grill member 106 is connected to the pan member 104. The upstanding outer portion 116 of the pan member 104 is positioned within the pocket 172 of the grill member 106 and is locked to the pan member 104 by the tab member 196 of the grill member 106 being positioned within the recess of one of the extensions 138 of the pan member 104. As there are a plurality of extensions 138 around the circumference of the pan member 104, the tab member 196 can be positioned within the recess of any one of the extensions 138 on the pan member 104, thus allowing for the easy connection of the grill member 106 to the pan member 104 as the grill member 106 and the pan member 104 need not be rotated relative to one another by more than sixty (60) degrees, in the preferred embodiment, in order to connect the grill member 106 to the pan member 104.
The upstanding inner portion 114 of the pan member 104 extends up into the aperture 376 of the inner drop tube member 110 and the aperture 284 of the outer drop tube member 108.
The wing members 302 of the outer drop tube member 108 are preferably positioned above the base portion 118 of the pan member 104 such that the apertures 376, 284 of the inner and outer drop tube members 110, 108, respectively, are in communication with the pan member 104 to define a first or lower gate G-1 which is preferably always provided for in the feeder assembly 100.
Reduction of Birds Raking Feed within the Feed Assembly 100The positioning of the wing members 302 which extend over the pan member 104 helps to reduce the amount of feed presented in the pan member 104 which the birds are capable of raking as the raking of feed can potentially cause the feed to become contaminated. Thus, because the birds cannot rake feed presented in the pan member 104 as freely as they could in some pan members of the prior art, the birds cannot rake the feed out of the pan member 104 onto the feeding surface of the poultry house where the feed will come into contact with waste and dirt, thus contaminating the feed.
Thus, the positioning of the wing members 302 within or on the pan member 104 provides a number of advantages and benefits to the overall growth and health of the birds, and to the poultry grower's costs and expenses involved in growing the birds.
Adjustable Upper and Lower Feed GatesIn accordance with the invention, the feeder assembly 100 can be used to present feed to birds of any size, whether they be young, small, immature birds, or older, larger, more mature birds. When birds are young and small, the birds typically require a generally high feed level in the pan member 104 so that the birds can find the feed and gain access to the feed. As the birds grow older and larger, the birds are able to find and gain access to the feed from interior portions of the pan member 104 and can obtain feed from raised pan members 104 if necessary. Thus, it is very desirable to be able to configure the feed level within the pan member 104 to any number of different heights, regardless of whether the feeder assemblies 100 are positioned on the feeding surface or are raised off of the feeding surface.
Adjustable Lower Feed Gate G-1The height of the lower feed gate G-1 can be adjusted, as desired by the poultry grower. The indicators 280 on the grill member 106, when in alignment with the arrow indicator 357 from the outer drop tube member 108, identify the height of the lower feed gate G-1. When the arrow indicator 357 is in alignment with the indicator 280 numbered “1”, the poultry grower knows that the smallest height of the lower feed gate G-1 is being provided, and that the feeder 100 is positively locked in this position because the protrusions 340 are positioned within the grooves 266 of the grill member 106 which are provided at a 90 degree angle from the indicator 280 numbered “1”. Conversely, when the arrow indicator 357 is in alignment with the indicator 280 numbered “6”, the poultry grower knows that the highest height of the lower feed gate G-1 is being provided, and that the feeder 100 is positively locked in this position because the protrusions 340 are positioned within the grooves 266 of the grill member 106 which are provided at a 90 degree angle from the indicator 280 numbered “6”. The arrow indicator 357 and the indicators 280 allow for the easy sight adjustment of the height of the lower feed gate G-1 by the poultry grower, as well as also ensure to the poultry grower that the feeder 100 is positively locked in such a position.
When the lower feed gate G-1 is at the smallest height, with the arrow indicator 357 being in alignment with the indicator 280 numbered “1”, the wing members 302 are positioned slightly above the base portion 118 of the pan member 104. When the wing members 302 are positioned slightly above the base portion 118 of the pan member 104, the helical thread 268 on the grill member 106 is meshed between the helical threads 330, 332 on the outer drop tube member 108 and the protrusions 340 on the outer drop tube member 108 are positioned within, and at a bottom of, the grooves 266 of the grill member 106 which are provided at a 90 degree angle from the indicator 280 numbered “1”. It should be noted that if the wing members 302 were not provided on the outer drop tube member 108, and if the helical threads 280, 330, 332 were configured properly, the lower feed gate G-1 could be closed as the bottom end 298 of the member 282 could be positioned on the base portion 118 of the pan member 104.
In order for the poultry grower to increase the height of the lower feed gate G-1 to provide more feed within the pan member 104 and to provide a higher feed level within the pan member 104, the poultry grower rotates the grill member 106 relative to the outer drop tube member 108, which is rotationally stable, such that the helical thread 268 of the grill member 106 rotates downwardly within and between the helical threads 330, 332 of the outer drop tube member 108, thus rotating the grill member 106 downwardly relative to the outer drop tube member 108. At the same time, the protrusions 340 on the outer drop tube member 108 are capable of being flexed inwardly and out of the grooves 266 of the grill member 106, as it is provided for on a retractable portion 334 of the outer drop tube member 108. As the grill member 106 is rotated downwardly relative to the outer drop tube member 108, the protrusions 340 will again protract into other grooves 266 of the grill member 106 to help retain the outer drop tube member 108 in the desired position based on the desired height of the lower feed gate G-1.
Thus, the poultry grower can easily adjust the height of the lower feed gate G-1 to provide for different levels and amounts of feed to be presented and retained by the pan member 104 by merely rotating the grill member 106 relative to the outer drop tube member 108, with more feed being presented when the lower feed gate G-1 is at a height defined by the arrow indicator 357 being in alignment with the indicator 280 numbered “6”, as illustrated in
The adjustment of the lower feed gate G-1 is performed without the lowering of the feeder assembly 100 to the feeding surface or the raising of the feeder assembly 100 off of the feeding surface.
It should be noted that the adjustment of the height of the lower feed gate G-1 is performed by the poultry grower without the poultry grower having to reach his/her hand into an inner portion of the feeder assembly as is required with prior art feeder assemblies. Rather, the poultry grower need only manipulate an exterior portion of the grill member 106 in order to change the size of the lower feed gate G-1. Thus, adjustment is facilitated and possible injuries to the poultry grower are eliminated as the poultry grower does not need to reach within the feeder assembly.
Adjustable Upper Feed Gate G-2With the feeder assembly 100, the poultry grower has the option of presenting the feed in the pan member 104 to the birds anywhere from a high feed level to a low feed level.
The low feed level is presented to the birds in the pan member 104 when the windows 434 of the inner drop tube member 110 are not in alignment with the windows 308 of the outer drop tube member 108. Thus, when the windows 308, 434 are not in alignment with one another, the windows 308 are sealed off by the first, second and third portions 378, 380, 382 of the inner drop tube member 110, forcing the feed to flow only through the lower feed gate G-1.
In order to present a higher feed level to the birds in the pan member 104, a second or upper feed gate G-2 is provided in the feeder assembly 100 by aligning the windows 434 of the inner drop tube member 110 with the windows 308 of the outer drop tube member 108. The upper feed gate G-2 is preferably a variable or adjustable feed gate as the feed level presented by the upper feed gate G-2 can be transitioned from a high level of feed to a low level of feed, with the low level of feed still being higher than the feed level provided by the lower feed gate G-1. The upper feed gate G-2, however, could be provided such that it is not a variable feed gate by changing the configuration of either of the windows 308, 434.
Preferably, for the highest feed level to be presented in the pan member 104, the inner drop tube member 110 is rotated within and relative to the outer drop tube member 108 such that the windows 434 of the inner drop tube member 110 are positioned into alignment with an upper portion of the windows 308 of the outer drop tube member 108, proximate to the first, second, third, sixth and seventh edges 310, 312, 314, 320, 322 such that feed flows through the upper feed gate G-2 and into the pan member 104, as illustrated in
In order to lower the feed level from the high feed level, but still provide a feed level that is higher than the feed level provided by the lower feed gate G-1, the inner drop tube member 110 is again rotated within and relative to the outer drop tube member 108 such that the windows 434 of the inner drop tube member 110 are positioned into alignment with a lower portion of the windows 308 of the outer drop tube member 108, proximate to the third, fourth, fifth and sixth edges 314, 316, 318, 320 such that feed flows through the upper feed gate G-2 and into the pan member 104, as illustrated in
By lowering the feed level even further, the inner drop tube member 110 is again preferably rotated within and relative to the outer drop tube member 108 such that the windows 308 of the outer drop tube member 108 are not in alignment with the windows 434 of the inner drop tube member 110, thus forcing the feed to flow through the lower feed gate G-1 and into the pan member 104, as illustrated in
No matter what position the upper feed gate G-2 is positioned in, i.e., allowing feed to flow therethrough or not allowing feed to flow therethrough, feed will always flow through the lower feed gate G-1 in the preferred embodiment. Of course, as the inner drop tube member 110 can be selectively adjusted to precisely position the amount and location of feed in the pan member 104 in a plurality of different positions, other than those heretofore discussed and which are merely representative positions for discussion and illustration purposes, relative to the outer drop tube member 108, the upper feed gate G-2 can thus, likewise, have a plurality of different positions such that the upper feed gate G-2 is, in essence, a variable feed gate such that the poultry grower can provide a smooth transition of feed from a high feed level to a low feed level. Of course, more positions of the inner drop tube member 110 relative to the outer drop tube member 108 can also be provided by changing the shape or configuration of the windows 308, 434 to provide different feed levels in the pan member 104.
It should be noted that the configuration of the windows 308 of the outer drop tube member 106 could be provided for on the inner drop tube member 108, in place of the windows 434 thereof, while the windows 434 of the inner drop tube member 108 could be provided for on the outer drop tube member 106, in place of the windows 308 thereof, if desired, as the same function would be performed and the same result achieved as the described preferred embodiment.
Thus, the adjustable upper and lower feed gates G-2, G-1 provide numerous advantages and benefits over feeder assemblies of the prior art. For instance, the windows 308 of the outer drop tube member 108 allow poultry growers to utilize a smooth transition from a high feed level, where feed flows through the variable upper feed gate G-2 and the lower feed gate G-1, to a low feed level, where feed flows only through the lower feed gate G-1. Prior art feeder assemblies having upper feed gates did not have practical means to allow for the poultry grower to make a smooth transition from a high feed level to a low feed level in accordance with the size and age of the birds. Contrarily, prior art feed assemblies, as a practical matter, only allowed for either a high feed level or a low feed level by vertically moving parts of the feeder assemblies to either open or close the upper feed gate.
The upper feed gate G-2 can also be utilized regardless of whether the feeder assembly 100 is raised off of, or lowered to, the feeding surface. Contrarily, prior art feeder assemblies typically activated the upper feed gate by removing the feeder assembly from the feeding surface. This feature of the feeder assembly 100 allows for a number of different management styles to be utilized by the poultry growers depending on their preferences. For instance, in some parts of the world, poultry growers typically prefer to raise feeder assemblies off of the feeding surface prior to the closing of the upper feed gates. In contrast, in the USA, poultry growers typically prefer to close the upper feed gates prior to the raising of the feeder assemblies off of the feeding surface. In any event, the poultry grower has numerous possibilities and configurations of how to present the feed to the birds, regardless of the size or age of the birds, with the upper feed gate G-2 being variable and adjustable, the lower feed gate G-1 being adjustable, and the feeder assembly 100 capable of being raised off of the feeding surface, all of which function independently of the other.
The poultry grower could also open the upper feed gate G-2 to any desired position, when it would normally be closed, in order to stimulate the eating of the feed by older birds, as it would give them a short term high feed level.
Also, in the preferred embodiment, by providing the feeder assembly 100 with a lower gate G-1 which is always open, feed is always allowed to flow through the feed supply conduit 102, into the apertures 346, 350 of the outer drop tube member 108, into the aperture 376 of the inner drop tube member 110, and through the lower feed gate G-1 to the pan member 104. Prior art feeder assemblies that utilized both upper and lower feed gates typically only allowed the feed to flow through one of the gates.
Cone of Pan Member 104 The upstanding cone or inner portion 104 of the pan member 104 extends higher from the base portion 118 of the pan member 104 than do cones of many prior art pan members. The cone 114 of the pan member 104 preferably extends to a height that is higher than the height of the windows 308, 434 of the outer and inner drop tube members 108, 110 in order to promote a high level of feed out of the upper feed gates G-2 as the feed will cascade downwardly and outwardly toward the upper feed gates G-2 after it comes into contact with the cone 114 of the pan member 104, as best illustrated in
As explained hereinabove, three different types of inner drop tube actuators 112a, 112b, 112c can be used to rotate the inner drop tube member 110.
With regard to inner drop tube actuator 112a, and as explained hereinabove, the extension member 451 of the inner drop tube member 110 extends through the aperture 362 of the outer drop tube member 108 and through the oval-shaped opening 518 of the inner drop tube actuator 112a. The inner drop tube actuator 112a is also capable of being linearly moved along the length of the feed supply conduit 102, but linear movement of the inner drop tube actuator 112a along the feed supply conduit 102 is limited by the conduit acceptor member 348 of the outer drop tube member 108, as best illustrated in
In order to actuate the rotation of the inner drop tube member 110 to adjust or vary the position of the upper feed gate G-2, as described hereinabove, the poultry grower moves the inner drop tube actuator 112a linearly along the length of the feed supply conduit 102. Linear movement of the inner drop tube actuator 112a forces movement of the extension member 451 of the inner drop tube member 110 within the aperture 362 of the outer drop tube member 108. As the aperture 362 of the outer drop tube member 108 is arcuate, the extension member 451 rotates around the aperture 362 of the outer drop tube member 108, thus, forcing the remainder of the inner drop tube member 110 to rotate. The rotation of the inner drop tube member 110 provides for the adjustment or varying of the position of the upper feed gate G-2 by forcing the windows 434 of the inner drop tube member 110 to be in or out of alignment with the windows 308 of the outer drop tube member 108.
The actuation of the inner drop tube member 110 to control the positioning of the windows 434 relative to the windows 308 of the outer drop tube member 108 can be done in a number of manners. In a first manner, a poultry grower can string cables from the circular cylindrical members 476 of the first and second end members 452, 454 of the inner drop tube actuator 112a. The cables can then be moved to different positions to force the inner drop tube actuator 112a to be linearly moved to different positions to force the inner drop tube actuator 112a to be linearly moved along the feed supply conduit 102, thus rotating the inner drop tube member 110. Such an operation would be preferably used mainly in connection with the movement of a single feeder assembly 100. In a second manner a lever can be connected to the inner drop tube actuator 112a to actuate the inner drop tube member 110. Such an operation would be preferably used mainly in connection with the movement of either a partial or total system of feeder assemblies 100. In a third manner, the inner drop tube actuator 112a can be connected to an electronics module that would be preprogrammed to linearly move the inner drop tube actuator 112a along the feed supply conduit 102 in a desired manner. Such an operation would be preferably used mainly in connection with the movement of an entire system of feeder assemblies 100.
As explained hereinabove, any means which can translate the linear movement thereof into the rotation movement of the inner drop tube member 110 is to be considered analogous and/or equivalent to the inner drop tube actuator 112a, including elimination of an actuator member and using one's hand instead.
With regard to the inner drop tube actuator 112b, and as explained hereinabove, the first fastening member 522 secures the L-bracket 520 to the extension member 451 of the inner drop tube member 110. Thus, in order to actuate the rotation of the inner drop tube member 110 to adjust or vary the position of the upper feed gate G-2, as described hereinabove, the poultry grower moves the inner drop tube actuator 112b.
The actuation of the inner drop tube member 110 to control the positioning of the windows 434 relative to the windows 308 of the outer drop tube member 108 is preferably done by the poultry grower stringing cables through the slots 544 of the second fastening member 524, inserting the threaded shank portion 542 of the second fastening member 524 through the aperture 534 of the second member 530 of the L-bracket 520, and then securing the nut member 526 over the threaded shank portion 542 of the second fastening member 524. By securing the nut member 526 over the threaded shank portion 542 of the second fastening member 524, the extension member 550 contacts the cable strung through the slot 544 and secures it within the slot 544. The cables can then be moved to different positions to force the inner drop tube actuator 112b to be moved to different positions, thus rotating the inner drop tube member 110. Of course, it is to be understood that other similar constructions of the inner drop tube actuator 112b could also be utilized to rotate the inner drop tube member 110.
With regard to inner drop tube actuator 112c, and as explained hereinbelow, the prong members 568, 570 secure the fastening member 552 to the extension member 451 of the inner drop tube member 110. Thus, in order to actuate the rotation of the inner drop tube member 110 to adjust or vary the position of the upper feed gate G-2, as described hereinabove, the poultry grower moves the inner drop tube actuator 112c.
The actuation of the inner drop tube member 110 to control the positioning of the windows 434 relative to the windows 308 of the outer drop tube member 108 is preferably done by the poultry grower stringing cables through the slots 566 of the threaded shank portions 558 of the fastening members 552, and then securing the nut member 554 over the threaded shank portion 558. By securing the nut member 554 over the threaded shank portion 558, the extension member 586 contacts the cable strung through the slot 566 and secures it within the slot 566. The cables can then be moved to different positions to force the inner drop tube actuator 112c to be moved to different positions, thus rotating the inner drop tube member 110. Of course, it is to be understood that other similar constructions of the inner drop tube actuator 112c could also be utilized to rotate the inner drop tube member 110.
Bird Welfare Features of the Feeder Assembly 100The structure of the feeder assembly 100 also provides for the overall welfare of the birds as they are feeding from the feeder assembly 100 by reducing detrimental physical effects to the birds caused by the birds feeding from the feeder assembly 100 and, thus, provides for a reduction of bird condemnation.
In the growing of birds, poultry growers typically try to grow birds which have large, healthy breasts as birds with large, healthy breasts will be the most commercially valuable to the poultry grower. As the birds are grown to have large breasts, the birds generally become front-heavy such that when the birds are eating from feeder assemblies, the birds tend to rest the front sides of their bodies, namely their breasts, on or against the pan or grill members, depending on the configuration of the feeder assemblies, to reduce the amount of weight that the birds must support while they eat. It should be noted that some birds are not raised for the purpose of large breasts because of the cut-up market, but it is still invaluable to have birds with healthy bodies.
Problems, however, can occur when the birds rest the front sides of their bodies on or against the pan or grill members. In particular, when the front sides of the birds rub against the pan or grill members, the front sides of the birds may become detrimentally physically effected, for instance, bruised. The detrimental physical effects to the birds' front sides can potentially cause health problems for the birds and can potentially cause the birds to eat less than the poultry grower would desire as the birds would become uncomfortable resting their front sides on or against the pan or grill members. The detrimental physical effects on the birds' front sides can also cause bird condemnation because after the removal of the birds' feathers, visual inspection of the birds' front sides can detect the detrimental physical effects thereon and, for instance, the effect on the color of the meat which is known to be a healthy color, thus possibly reducing the quality of grade given to the birds. Obviously, the lower quality of grade that is given to the birds, the less commercially valuable the birds become to the poultry grower. The feeder assembly 100 helps to prevent the foregoing by the configuration of the grill member 106 on both the rim member 154 and the plurality of spoke members 156.
As best illustrated in
As best illustrated in
Thus, the configuration of the grill member 106 helps assist in the overall health and comfort of the birds, as the grill member 106 is designed to be comfortable to the birds which leads to the birds staying longer at the feeder assembly 100 and, consequently, eating more feed.
Shallow/Deep Pan DepthIt is an advantage that the feeder assembly 100 has both the capabilities of a shallow pan depth for young birds to have access to the feed in the pan member 104, and a deep pan depth for older birds to feed from the pan member 104.
The shallow and deep pan depths are provided by the rim member 154 of the grill member 106 when the feeder assembly 100 is positioned on the feeding surface. As best illustrated in
Thus, the feeder assembly 100 provides for the functionality of both a shallow pan depth feeder assembly necessary for younger birds and for a deep pan depth feeder assembly which is desirable for older birds such that the poultry grower need not have two sets of feeder assemblies, one with a shallow pan depth and one with a deep pan depth. The shallow/deep pan depths also require no work of any kind by the poultry grower or vertical movement of the feeder assembly 100 to be effected. The pan depths are naturally provided by use of the feeder assembly 100, with only the size of the bird defining which pan depth the birds utilize.
Prevention of Material Buildup in the Feeder Assembly 100The inner drop tube member 110 preferably includes the apertures 450 to allow dust, feed or other material to flow therethrough to prevent the buildup of excess material in the feeder assembly 100 which could potentially cause problems to the feeder assembly 100.
Wide Eating AreaThe base portion 118 of the pan member 104 is wider than those generally provided in prior art feeder assemblies. The wider base portion 118 of the pan member 104 provides smaller birds with more room to eat, i.e., access to the feed presented in the pan member 104. The wider base portion 118 of the pan member 104 also provides a visually larger feed area to the birds which encourages the birds to eat the feed from the pan member 104.
Cleaning of the Feeder Assembly 100The feeder assembly 100 can be easily cleaned by the poultry grower. Prior to the cleaning of the feeder assembly 100, the poultry grower can rotate the pan member 104 and the grill member 106 relative to one another such that the tab member 196 of the grill member 106 is not positioned within the recess of one of the extensions 138 of the pan member 104. The hook member 144 on the pan member 104 is then positioned within the slot 208 of the grill member 106 to suspend the pan member 104 from the grill member 106. Thus, once the pan member 104 is suspended from the grill member 106, the poultry grower can commence cleaning of the feeder assembly 100 as the suspending of the pan member 104 from the grill member 106 allows the poultry grower to easily access all parts of the feeder assembly 100.
The inner drop tube member 110 can also, for instance, be removed from within the outer drop tube member 108 by pushing in the ring member 424 of the inner drop tube member 110 such that the ring member 424 no longer rests on the ledges 328 of the portions 324 of the member 282 of the outer drop tube member 108, allowing the inner drop tube member 110 to be removed from the outer drop tube member 108. The inner drop tube member 110 can later be reinserted within the outer drop tube member 108 as the ring member 424 will flex inwardly until the inner drop tube member 110 can rest on the ledges 328. Thus, the ledges 328 of the portions 324 are capable of holding the inner drop tube member 110 within the outer drop tube member 108.
Structure of the Feeder Assembly 600 Attention is invited to the second embodiment of the feeder assembly 600 which is shown in
It should be noted that the elements of the reference numerals of the feeder assembly 600 are similar to like elements of the reference numerals of the feeder assembly 100, with elements having reference numerals in the six hundreds being similar to the elements having reference numerals in the one hundreds, elements having reference numerals in the seven hundreds being similar to the elements having reference numerals in the two hundreds, and elements having reference numerals in the eight hundreds being similar to the elements having reference numerals in the three hundreds.
The illustrated feeder assembly 600 generally includes a pan member 104, a grill member 106, and a drop tube member 608.
The pan member 104 of the second embodiment is identical to the pan member 104 provided for in the first embodiment and, therefore, the details and advantages of the pan member 104 of the second embodiment will not be discussed herein. Likewise, the grill member 106 of the second embodiment is identical to the grill member 106 provided for in the first embodiment and, therefore, the details and advantages of the grill member 106 of the second embodiment will not be discussed herein. Thus, only the differences in structure and function between the first and second embodiments will be discussed herein.
Drop Tube Member 608 Attention is now directed to the drop tube member 608, which is best illustrated in
The drop tube member 608 includes a member 782 having an aperture 784 therethrough such that the member 782 is hollow. The member 782 preferably has a first portion 786, a second portion 788, a third portion 790, a fourth portion 792, a fifth portion 794, and a sixth portion 796. The first portion 786 extends upwardly and inwardly from a bottom end 798 of the member 782 to a first end of the second portion 788 such that the member 782 has an inner diameter proximate to the bottom end 796 thereof which is larger than an inner diameter proximate to the first end of the second portion 788. The second portion 788 extends inwardly from the first end thereof to a first end of the third portion 790 such that the member 782 has an inner diameter proximate to the first end of the third portion 790 which is slightly smaller than the inner diameter proximate to the first end of the second portion 788. The third portion 790 extends upwardly and inwardly from the first end thereof to a first end of the fourth portion 792 such that the member 782 has an inner diameter proximate to the first end of the fourth portion 792 which is smaller than the inner diameter proximate to the first end of the third portion 790. The fourth portion 792 extends upwardly and inwardly from the first end thereof to a first end of the fifth portion 794 such that the member 782 has an inner diameter proximate to the first end of the fifth portion 794 which is smaller than the inner diameter proximate to the first end of the fourth portion 792. The fifth portion 794 extends inwardly from the first end thereof to a first end of the sixth portion 796 such that the member 782 has an inner diameter proximate to the first end of the sixth portion 796 which is slightly smaller than the inner diameter proximate to the first end of the fifth portion 794. The sixth portion 796 extends upwardly from the first end thereof to a top end 800 of the member 782, such that the member 782 has an inner diameter at the top end 800 thereof which is equivalent to the inner diameter proximate to the first end of the sixth portion 796.
The drop tube member 608 further preferably includes a plurality of wing members 802 extending therefrom. The wing members 802 are connected to an outer surface 804 of the member 782 along the first, second and third portions 786, 788, 790 thereof. The wing members 802 are curved outwardly and downwardly from the outer surface 804 of the member 782 such that a bottom end 806 of the wing members 802 is positioned below the bottom end 798 of the member 782, thus allowing the aperture 784 of the member 782 to be open at the bottom end 798 thereof. The bottom end 806 of the wing members 802 is preferably flat or horizontal. In a preferred embodiment, the plurality of wing members 802 number eight (8) and are positioned equidistantly apart from one another, such that each wing member 802 is positioned forty-five (45) degrees apart from one another. It should be noted that the drop tube member 608 could be provided without the wing members 802 if desired.
The drop tube member 608 further preferably includes a helical track which is preferably a pair of helical threads 830, 832 which wind around the outer surface 804 of the sixth portion 796 of the member 782. The helical threads 830, 832 begin winding proximate to the top end 800 of the member 782 to a position approximately lower than the midpoint between the top end 800 and the connection between the fifth and sixth portions 794, 796. The helical threads 830, 832 are spaced apart from one another a distance which is slightly larger than the size of the helical thread 768 of the collar member 158 of the grill member 106.
As best illustrated in
The retractable portion 834 also has a protrusion 840 extending outwardly therefrom. The protrusion 840 is capable of extending into the grooves 266 of the collar member 158 of the grill member 106 as will be discussed in more detail herein and, during rotation of the drop tube member 608 relative to the grill member 106, allows the retractable portion 834 to be flexed inwardly when the protrusion 840 is not extended within one of the grooves 266 of the collar member 158. In the preferred embodiment, the retractable portions 834 number two (2) and are positioned equidistantly from one another such that they are positioned one-hundred eighty (180) degrees from one another. The helical threads 830, 832 are cut away where they cross the retractable portion(s) 834.
The drop tube member 608 further preferably includes a top member 842 on the member 782. The top member 842 extends perpendicularly inwardly from the top end 800 of the sixth portion 796 of the member 782. The top member 842 covers a portion of the aperture 784 at the top end 800 of the member 782.
The drop tube member 608 further preferably includes an inner cylindrical portion 844, as best illustrated in
The drop tube member 608 further preferably includes a conduit acceptor member 848. The conduit acceptor member 848 has an aperture 850 therethrough which is in communication with the aperture 846 of the inner cylindrical portion 844 and, thus, the aperture 784 of the member 782. The conduit acceptor member 848 extends upwardly from the top member 842 of the member 782, but does not cover the entire top member 842.
The conduit acceptor member 848 generally includes a first side member 852, a second side member 854 and an arced intermediate member 856. The first and second side members 852, 854 are identical and are distanced from one another a predetermined distance and have circular openings 858 therethrough. Tops of the first and second side members 852, 854 are also arced in conformance with the circular openings 858. The arced intermediate member 856 is generally an upside down U-shaped piece and generally extends from the top member 842 between the first and second side members 852, 854 along their respective edges back to the top member 842. The feed supply conduit 102 is capable of extending through the openings 858 of the first and second side members 852, 854 and of allowing feed to drop therefrom into the aperture 850 of the conduit acceptor member 848.
One side of the arced intermediate member 856 preferably has an indicator 857 provided thereon. The indicator 857 is preferably an arrow which is pointing down toward the top member 842 of the outer drop tube member 608. The purpose for the indicator 857 will be discussed further herein under the section heading “Adjustable Feed Gate G-1”.
The openings 858 further have notches 860 therein at the top thereof to accept a protrusion (not shown) of the feed supply conduit 102 to prevent the feed assembly 600 from being moved relative to the feed supply conduit 102.
It should be noted that the configuration of the conduit acceptor member 848 may be formed to fit over various types of feed supply conduits.
In a preferred embodiment, the conduit acceptor member 848 further includes at least one member 862 extending upwardly from the arced intermediate member 856 which is capable of accepting and retaining a roost wire. The member 862 preferably has reinforcing members 864 extending from the member 862 to the arced intermediate member 856.
A plurality of reinforcing members 866 which extend from both the first and second side members 852, 854 to the top member 842 of the member 782 are preferably provided. In a preferred embodiment, the reinforcing members 866 number four (4) with two (2) of the reinforcing members 866 extending from the first side member 852 to the top member 842 of the member 782 and two (2) of the reinforcing members 866 extending from the second side member 854 to the top member 842 of the member 782.
Operation of the Feeder Assembly 600 Assembly of the Feeder Assembly 600 In order to utilize the feeder assembly 600, the parts of the feeder assembly 600 must be assembled to that as best illustrated in
The conduit acceptor member 848 of the drop tube member 608 is positioned around the feed supply conduit 102 with an opening in the feed supply conduit 102 being in communication with the apertures 782, 846, 850 of the drop tube member 608.
The grill member 106 is positioned around and connected to the drop tube member 608. The helical thread 268 of the grill member 106 is positioned between the helical threads 830, 832 of the drop tube member 608 such that the grill member 106 can be rotatably moved relative to the drop tube member 608. The protrusions 840 on the drop tube member 608 are temporarily locked into position with the grooves 266 of the grill member 106.
The grill member 106 is connected to the pan member 104. The upstanding outer portion 116 of the pan member 104 is positioned within the pocket 162 of the grill member 106 and is locked to the pan member 104 by the tab member 196 of the grill member 106 being positioned within the recess 140 of one of the extensions 138 of the pan member 104. As there are a plurality of extensions 138 around the circumference of the pan member 104, the tab member 196 can be positioned within the recess 140 of any one of the extensions 138 on the pan member 104, thus allowing for the easy connection of the grill member 106 to the pan member 104 as the grill member 106 and the pan member 104 need not be rotated relative to one another by more than sixty (60) degrees, in the preferred embodiment, in order to connect the grill member 106 to the pan member 104.
The upstanding inner portion 114 of the pan member 104 extends up into the aperture 784 of the drop tube member 608.
The wing members 802 of the drop tube member 608 are positioned above the base portion 118 of the pan member 104 such that the aperture 784 of the drop tube member 608 is in communication with the pan member 104 to define a gate G-1.
Reduction of Birds Raking Feed within the Feed Assembly 600The positioning of the wing members 802 which extend over the pan member 104 helps to reduce the amount of feed presented in the pan member 104 which the birds are capable of raking as the raking of feed can potentially cause the feed to become contaminated. Thus, because the birds cannot rake feed presented in the pan member 104 as freely as they could in some pan members of the prior art, the birds cannot rake the feed out of the pan member 104 onto the feeding surface of the poultry house where the feed will come into contact with waste and dirt, thus contaminating the feed.
Thus, the positioning of the wing members 802 within or on the pan member 104 provides a number of advantages and benefits to the overall growth and health of the birds, and to the poultry grower's costs and expenses involved in growing the birds.
Adjustable Feed Gate G-1The height of the feed gate G-1 can be adjusted, as desired by the poultry grower. The indicators 280 on the grill member 106, when in alignment with the arrow indicator 857 from the outer drop tube member 608, identify the height of the feed gate G-1. When the arrow indicator 857 is in alignment with the indicator 280 numbered “1”, the poultry grower knows that the smallest height of the feed gate G-1 is being provided, and that the feeder 600 is positively locked in this position because the protrusions 840 are positioned within the grooves 266 of the grill member 106 which are provided at a 90 degree angle from the indicator 280 numbered “1”. Conversely, when the arrow indicator 857 is in alignment with the indicator 280 numbered “6”, the poultry grower knows that the highest height of the feed gate G-1 is being provided, and that the feeder 600 is positively locked in this position because the protrusions 840 are positioned within the grooves 266 of the grill member 106 which are provided at a 90 degree angle from the indicator 280 numbered “6”. The arrow indicator 857 and the indicators 280 allow for the easy sight adjustment of the height of the feed gate G-1 by the poultry grower, as well as also ensure to the poultry grower that the feeder 600 is positively locked in such a position.
When the feed gate G-1 is at the smallest height, with the arrow indicator 857 being in alignment with the indicator 280 numbered “1”, the wing members 802 are positioned slightly above the base portion 118 of the pan member 104. When the wing members 802 are positioned slightly above the base portion 118 of the pan member 104, the helical thread 268 on the grill member 106 is meshed between the helical threads 830, 832 on the drop tube member 608 and the protrusions 840 on the drop tube member 608 are positioned within, and at a bottom of, the grooves 266 of the grill member 106 which are provided at a 90 degree angle from the indicator 280 numbered “1”. It should be noted that if the wing members 802 were not provided on the drop tube member 608, and if the helical threads 268, 830, 832 were configured properly, the feed gate G-1 could be closed as the bottom end 798 of the member 782 could be positioned on the base portion 118 of the pan member 104.
In order for the poultry grower to increase the height of the feed gate G-1 to provide more feed within the pan member 104 and to provide a higher feed level within the pan member 104, the poultry grower rotates the grill member 106 relative to the drop tube member 608, which is rotatably stable, such that the helical thread 268 of the grill member 106 rotates downwardly within and between the helical threads 830, 832 of the drop tube member 608, thus rotating the grill member 106 downwardly relative to the drop tube member 608. At the same time, the protrusions 840 on the drop tube member 608 are capable of being flexed inwardly and out of the grooves 266 of the grill member 106, as they are provided for on retractable portions 834 of the drop tube member 608. As the grill member 106 is rotated downwardly relative to the drop tube member 608, the protrusions 834 will again protract into other grooves 266 of the grill member 106 in the desired position based on the desired height of the feed gate G-1.
Thus, the poultry grower can easily adjust the height of the feed gate G-1 to provide for different levels and amounts of feed to be presented and retained by the pan member 104 by merely rotating the grill member 106 relative to the drop tube member 608, with more feed being presented when the feed gate G-1 is at a height defined by the arrow indicator 857 being in alignment with the indicator 280 numbered “6”, than at a height defined by the arrow indicator 857 being in alignment with the indicator 280 numbered “1”, as best illustrated in
The adjustment of the feed gate G-1 is performed without the lowering of the feeder assembly 600 to the feeding surface or the raising of the feeder assembly 600 off of the feeding surface.
It should be noted that the adjustment of the height of the feed gate G-1 is performed by the poultry grower without the poultry grower having to reach his/her hand into an inner portion of the feeder assembly as is required with prior art feeder assemblies. Rather, the poultry grower need only manipulate an exterior portion of the grill member 106 in order to change the size of the feed gate G-1. Thus, adjustment is facilitated and possible injuries to the poultry grower are eliminated as the poultry grower does not need to reach within the feeder assembly.
Structure of the Feeder Assembly 900 Attention is invited to the third embodiment of the feeder assembly 900 which is illustrated in
It should be noted that the elements of the reference numerals of the feeder assembly 900 are similar to like elements of the reference numerals of the feeder assembly 100, with elements having reference numerals in the nine hundreds being similar to the elements having reference numerals in the one hundreds and elements having reference numerals in the ten hundreds being similar to the elements having reference numerals in the two hundreds.
The illustrated feeder assembly 900 generally includes a pan member 904 and a drop tube assembly 907. The drop tube assembly 907 of the feeder assembly 900 will not be discussed, however, as it is not considered to be germane to the invention of the third embodiment of the invention as a drop tube assembly of the type disclosed herein with regard to the first and second embodiments, or a drop tube assembly of the type disclosed in prior art patents, could be utilized and still achieve the objects of the invention. The pan member 904 of the third embodiment is configured to have parts similar to both the pan member 104 and the grill member 106, as the feeder assembly 900 does not have a grill member.
Attention is now directed to the pan member 904. The pan member 904 has at least an upstanding outer portion 916 and a base portion 918 which are integrally formed. An outer surface 920 of the pan member 904 at the base portion 918 is capable of resting on a feeding surface of a poultry house, such as a floor or the ground.
The upstanding outer portion 916 preferably has a rim member 954 thereon at a top thereof. The rim member 954, in a preferred embodiment, is generally circular, although the configuration of the rim member 954 could be formed in a manner other than circular in order to achieve the objects of the invention. A side rim portion 960 of the rim member 954 has an outer surface 968, and is commensurate with an outer surface 920 of the upstanding outer portion 916.
The outer surface 968 of the side rim portion 960 is formed from a plurality of projections 974. In a preferred embodiment, and preferably for use with smaller birds, the plurality of projections 974 number twelve (12) and are spaced equidistantly apart from one another with a thirty (30) degree angle between the centers of the projections 974. In another preferred embodiment, and preferably for use with larger birds, the plurality of projections 974 number eight (not shown) and are spaced equidistantly apart from one another with a forty-five (45) degree angle between the centers of the projections 974.
In a preferred embodiment, and as best illustrated in
Also, in a preferred embodiment, an upper edge 986 of each projection 974 is formed of a first concave edge 988 at one end thereof, a second concave edge 990 at an opposite end thereof, and a convex edge 992 between the first and second concave edges 988, 990, as best illustrated in
The rim member 954 in a preferred embodiment also has a top rim portion 1010. The top rim portion 1010 has a top surface 1012 which is defined between an outer edge 1014 and an inner edge 1016 of the top rim portion 1010. When viewed in a side-elevational view, as in
When viewed in side-elevational view, as best illustrated in
The outer edge 1014 of the top surface 1012 is curved such that the outer edge 1014 is curved inwardly and downwardly at the valley portions 1020 of the top surface 1012 and curved outwardly and upwardly at the peak portions 1018 of the top surface 1012.
The rim member 954 in a preferred embodiment also has a curved rim portion 1022. As best illustrated in
The purpose of this configuration of the rim member 954 allows for a front portion of a bird's body to conform thereagainst when the bird feeds from the feeder assembly 900 such that detrimental physical effects to the body of the bird are not caused, or are at least minimized, when the bird feeds from the feeder assembly, as will be discussed further herein under the heading “Bird Welfare Features Of The Feeder Assembly 900”. It should be noted that the configuration of the rim member 954 and the pan member 904 could be formed in a manner other than described hereinabove in order to achieve the objects of the invention, such that a front portion of a bird's body can conform thereagainst when the bird feeds from the feeder assembly 900 such that detrimental physical effects to the body of the bird are not caused, or are at least minimized, when the bird feeds from the feeder assembly 900.
Bird Welfare Features of the Feeder Assembly 900The structure of the feeder assembly 900 provides for the overall welfare of the birds as they are feeding from the feeder assembly 900 by reducing detrimental physical effects to the birds caused by the birds feeding from the feeder assembly 900 and, thus, provides for a reduction of bird condemnation.
In the growing of birds, poultry growers typically try to grow birds which have large, healthy breasts as birds with large, healthy breasts will be the most commercially valuable to the poultry grower. As the birds are grown to have large breasts, the birds generally become front-heavy such that when the birds are eating from feeder assemblies, the birds tend to rest the front sides of their bodies, namely their breasts, on or against the pan or grill members, depending on the configuration of the feeder assemblies, to reduce the amount of weight that the birds must support while they eat. It should be noted that some birds are not raised for the purpose of large breasts because of the cut-up market, but it is still invaluable to have birds with healthy bodies.
Problems, however, can occur when the birds rest the front sides of their bodies on or against the pan or grill members. In particular, when the front sides of the birds rub against the pan or grill members, the front sides of the birds may become detrimentally physically effected, for instance, bruised. The detrimental physical effects to the birds' front sides can potentially cause health problems for the birds and can potentially cause the birds to eat less than the poultry grower would desire as the birds would become uncomfortable resting their front sides on or against the pan or grill members. The detrimental physical effects on the birds' front sides can also cause bird condemnation because after the removal of the birds' feathers, visual inspection of the birds' front sides can detect the detrimental physical effects thereon and, for instance, the effect on the color of the meat which is known to be a healthy color, thus possibly reducing the quality of grade given to the birds. Obviously, the lower quality of grade that is given to the birds, the less commercially valuable the birds become to the poultry grower. The feeder assembly 900 helps to prevent the foregoing by the configuration of the rim member 954 of the pan member 904.
As best illustrated in
Thus, the configuration of the pan member 904 helps assist in the overall health and comfort of the birds, as the pan member 904 is designed to be comfortable to the birds which leads to the birds staying longer at the feeder assembly 900 and, consequently, eating more feed.
Shallow/Deep Pan DepthIt is an advantage that the feeder assembly 900 has both the capabilities of a shallow pan depth for young birds to have access to the feed in the pan member 904, and a deep pan depth for older birds to feed from the pan member 904.
The shallow and deep pan depths are provided by the rim member 954 of the pan member 904 when the feeder assembly 900 is positioned on the feeding surface. As best illustrated in
Thus, the feeder assembly 900 provides for the functionality of both a shallow pan depth feeder assembly necessary for younger birds and for a deep pan depth feeder assembly which is desirable for older birds such that the poultry grower need not have two sets of feeder assemblies, one with a shallow pan depth and one with a deep pan depth. The shallow/deep pan depths also require no work of any kind by the poultry grower or vertical movement of the feeder assembly 900 to be effected. The pan depths are naturally provided by use of the feeder assembly 900, with only the size of the bird defining which pan depth the birds utilize.
While preferred embodiments of the present invention are shown and described, it is envisioned that those skilled in the art may devise various modifications of the present invention without departing from the spirit and scope of the appended claims.
