Abstract: A feeder for pigs includes a hopper and a trough for receiving the feed where an elongate opening is defined by an elongate shelf to control the amount of feed discharged from the hopper to the trough. An adjustment linkage for lifting the shelf against the weight of feed in the hopper includes a first lift screw and a second lift screw each for applying a lifting force to the elongate adjustment member located at spaced positions from the end walls of the hopper. Each of the screws includes a gear box with a shaft connected between the two gear boxes to communicate drive therebetween for simultaneous operation of the lift screws by a hand crank connected to one at the top of the feed in the hopper.

Abstract: A feeder unit for pigs has an elongate trough with a hopper mounted over the trough for depositing feed downwardly and a feed dispensing control system at a bottom of the hopper so as to supply feed downwardly to make up feed taken by the pigs. The hopper includes four upstanding side walls forming an elongate rectangular open top edge with an open upper guide mouth located centrally above the top edge for locating a downspout of a feed supply system. The open top is covered by two inclined walls each extending upwardly from a long top edge of a respective one of the side walls and inwardly of the side wall of the hopper toward the open upper guide mouth and by two hinged dust covers extending from the short edges to the mouth.

Abstract: A feeder for pigs as they grow continually from weanling size to finisher pig size includes a trough and a shelf with a water pipe located underneath the shelf with a plurality of water dispensing nipples operable by the pigs to dispense water downwardly into the trough for mixing with feed in the trough. The shelf is fixed in height at a common height for use by the pigs both as weanling size and as they grow to finisher size so that it is not adjustable to accommodate growth. This is obtained by selecting the dimensions of the height of the shelf relative to the water nipples and the side walls and the shape of the shelf to allow the required access.

Abstract: A feeder for feeding animals has a trough with two opposed outwardly inclined front walls over which the animals can reach for taking feed from the trough and a feed hopper for discharging feed downwardly onto a shelf above the trough. Water is supplied into the trough through a pipe along the trough underneath the shelf with a series of animal actuated nipples so that the animals may take the feed dry on the shelf or wet from the trough. A valve is provided at one end wall through which the water supply to the pipe passes, the valve having a plurality of separate orifices of different flow area and a manually operable control for selecting one of the plurality of orifices for passage of the water from the supply to the pipe.

Abstract: An animal feeder includes two feeder sections arranged end to end with a common hopper extension feeding individual hoppers above a shelf onto which feed can fall to be taken by the animal or dropped into a trough below the shelf. The height of the shelf is adjustable to change the feed rate by straps which are adjustable by a common longitudinal bar which is located at a selected adjustment position by meshing teeth. The portion of the lever is movable in a direction away from the plate a non-meshing position in which the bar can rotate around the pivot axis. A common water supply extends along both feeders and is heated by a common heating element.

Abstract: A cooking grill has a container with a heating bowl inside one end wall with a fuel pellet feed for combustion within the bowl and an automatic igniter for starting the combustion. A grate is arranged over the heating bowl at the first end of the container and over the part of the container beyond the heating bowl. An arch-shaped cover underneath the grate acts to spread heat along the container and onto parts of the grate beyond the heating bowl and to carry liquid toward the second end of the container for collection. The cover has a first portion at the heating bowl with slots for direct release of searing heat to food products on the grate with the remainder of the cover being substantially imperforate. A slide portion is provided to close the slots.

Abstract: A rack for storing elongate core sample boxes is formed from two separate frames each having three upright posts formed of tubular steel and a plurality of steel tubes extending across between the posts and welded to the posts. The frames can be transported in assembled form and then connected across the top and bottom of the uprights by metal bridging members with C-shaped inserts into the ends of the posts. The structure is held together and braced by diagonal braces which attach to tabs on the bridging members by a wedge drive into a slot in the tab.

Abstract: Euthanasia of birds is carried out by locating a tool on the neck of the bird and crushing the neck between two co-operating members each having a front face for engaging the neck which is sufficiently blunt to prevent cutting of the skin of the neck during the crushing action so as to prevent escape of blood from the neck with the members being held separated at an end of the crushing action to prevent severing of the neck. The members can be driven together for example by hand pressure or on a frame by a foot lever or can be provided as a pair of counter-rotating wheels.

Abstract: A one way gate primarily for pigs is located between a pair of parallel panels to be mounted in a fence line and includes two gate portions each defined by a transverse rail across the passage between the panels at a height above the passage and a plurality of fingers hanging from the rail separately pivotal in one direction only to the animal to pass and prevented from rotation in the opposite direction. The distance between the gate portions is less than 3.0 feet so as to be less than the length of the animal to prevent an animal being located between the rails and greater than 0.5 feet such that an animal attempting to lift the second fingers cannot simultaneously lift the first fingers.

Abstract: Gestating sows are housed in a series of gestation stalls arranged in a row and backing onto an open alley along a rear of the row of stalls into which the sow can enter by backing out of the stall. A common trough extends along the front of the stalls and is fastened to the floor by fasteners which connect trough sections end to end. The common trough provides a support for the front end of the side walls defining the stalls. A rear gate closes the rear of each stall and connects to a front gate of the stall operable to close the rear gate by the sow as it moves in the stall toward the front. The rear gate latches closed to prevent entry of another sow but is releasable by rear pressure on the rear gate from the sow backing out.

Abstract: An animal feeder includes a hopper above a shelf onto which feed can fall to be taken by the animal or dropped into a trough below the shelf. The height of the shelf is adjustable in a course movement to move the shelf from a low height for smaller animals to a raised height for the animal after they have grown. The shelf is also adjustable in fine movement to change the width of the opening through which the feed passes to control feed rate. The shelf is carried on straps which extend along the end walls of the hopper and are movable by an adjustment linkage defined by a plate carried on the end wall and a manually adjustable lever mounted for pivotal movement on the plate. The lever has two pivot positions on the plate providing the two course adjustments and two graduated scales for the fine adjustment each cooperating with a respective pivot position.
