  • Patent number: 4557014
    Abstract: Class workpieces, such as hog carcasses, of varying dimension, points of contour and shape are moved from storage on an overhead rail conveyer hanging vertically head down and are driven through break-up stations at a constant speed. Driven side belts moving at the same speed contact the carcasses in the work stations and hold them steady against oscillation. A saw or tool at each station is supported on a lead screw assembly for up and down movement. The lead screw is directionally and incrementally driven by a lead screw assembly at each station to locate each saw to perform work on the carcass. The saws at each station successively cut off the shoulder, loin-belly and ham as the carcasses move through the stations. The shoulder, loin-belly and ham fall by gravity onto conveyers when cut off by the saws. Manual means are provided to control the position of the saws as observed by the operator.

  • Patent number: 4252136
    Abstract: An erectable-collapsible enclosure structure having a top frame over which a flexible tent is draped leading to a bottom support to which the tent is attached. Two sets of upper and lower legs are pivotally connected at one end to the top frame and bottom support respectively and are pivotally connected to one another at their extending ends in a bent knee joint. The knee joints of each set lie on the opposite side of the knee joint of the other set so that the legs by-bass one another adjacent the knee joints. The top frame is manually raisable and lowerable relative to the bottom support to erect and collapse the structure. A pin placed between the upper and/or lower legs at their point of cross-over rigidly locks the structure in its erected position. Springs may be connected to the legs to assist in raising the enclosure and for holding it in its erected position. Hand levers connected to the bottom legs provide added means to operate the apparatus.

  • Patent number: 4252319
    Abstract: Golf swing training apparatus for advising a player of the sequence of the force factors in the swing of a club in a golf shot comprising a housing having an upper end flexibly mountable on the shaft of a club at a point adjacent the top of the off-target hand and a lower end at the bottom of the off-target hand in gripping the club. The upper end is movably attached to the shaft to allow the housing to rock on the shaft away from and toward the target during the swing. The housing separates the player's off-target hand from direct contact with the shaft and the housing's rockability disassociates off-target side direct control and direct application of force on the shaft during the backswing and the first part of the downswing. This tends to substantially reduce off-target side influence in the swing leaving the player in the position where he is influenced to exert initial dominant control and force of the swing through his target side.

  • Patent number: 4227562
    Abstract: Vehicular road traction apparatus feeds a traction portion of an endless chain between a tire and the road surface and a recirculating portion of the chain is picked up aft of the tire and fed into a conduit which conducts it back to a point fore of the tire where it is fed continuously under the tire as the traction portion. The conduit is supported in position by arms and pivot pins so that the conduit may be moved between the aforesaid feeding position to a non-feeding position where the chain is held away from the tire. A cable moves the conduit between the two positions. The conduit may be hinged midway in its length so as to move its feeding and pick-up ends farther apart to stretch the chain taut in the non-feeding position. The conduit may be located outside or inside the tire. When located inside the tire, a skid plate and guide bar assist the supporting means to locate the feeding end of the conduit in proper feeding position.

  • Patent number: 4184579
    Abstract: Apparatus for selectively by-passing, stopping, and releasing loads traveling on a conveyer having a case equipped with a stop arm and a stop lever on a pivotal stop shaft. The stop arm is swung to a stopping position above the conveyer to stop a load by pivotal movement of the stop shaft and stop lever in one direction and is swung to a non-stopping position not above the conveyer by pivotal movement of the stop shaft and stop lever in the other direction. A blocker leg is pivotally mounted at one end on the case and has an outer end engageable with the stop lever. When the stop arm, stop shaft, and stop lever are in their stopping position for the purpose of stopping a load, a spring or power means swings the blocker leg to abut its outer end against the stop lever so that when the load encounters the stop arm, the inertia and momentum forces of stopping the load is borne by the blocker leg and not borne by the spring or power means.

  • Patent number: 4173274
    Abstract: Conveyer load shunting apparatus having a housing with a main shaft equipped with a radial shunt bar extending over the conveyer to divert a load traveling on one conveyer to another. A lever on the main shaft is swung by a solenoid via a push-pull rod to swing the shunt bar from neutral to a shunting position. A spring biases the shunt bar to neutral and the solenoid armature extended. A horizontal rocker bar extends from the housing into the conveyer and has a radial leg equipped with a load engaging wheel. A spring and a radial switch bar on the rocker shaft biases the rocker shaft angularly to swing the wheel to a neutral position below the conveyer. A radial blocker arm on the rocker shaft has an end which is engageable with a peg on the lever of the main shaft to block the angular position of the main shaft with the shunt bar in shunt position. Thus the weight of the load holds the apparatus in shunt position with no strain on the solenoid.

  • Patent number: 4154995
    Abstract: Unitary switch mounting and actuating apparatus, particularly suitable for use on automatic conveyer systems, comprises a case having a back wall with an aperture formed therein and two spaced side walls. A shaft is pivotally mounted between the side walls opposite the aperture in the back wall. An externally threaded nipple is welded to the back wall over the aperture therein. A radial leg is fixed on the shaft and extends through the aperture and nipple to a contact foot. A radial arm is fixed on the shaft. A torsion spring surrounds the shaft and resiliently urges the leg and arm into the unactuated position. A platform welded to the case supports a switch with its actuation element aligned with the radial arm. Movement of the leg from its unactuated position moves the shaft angularly and swings the radial arm to depress the actuation element of the switch to change the condition of the switch.

  • Patent number: 4128281
    Abstract: Auxiliary axial thrust bearing apparatus having a case abuttable on a base at one end with the other end supporting an axial thrust bearing. The case and bearing surround the shaft which is to be axially supported. A sleeve, spring or other spacer lie co-axially of the shaft between the bearing and the load or thrust member secured to the shaft. Axial force on the shaft is supported by the apparatus via the case abutting the base and the bearing abutting the load or thrust member on the shaft. The case has a layer of resilient material lying between the bearing and the case and between the case and the base to permit the case and/or the bearing to move to a position of dynamic balance concentric with the dynamic center of balance of the shaft. The resilient layer also damps vibration. A torque arm may extend from the case to the base to resist angular movement of the case relative to the base and/or the end of the case at the base may be serrated to resist relative angular movement.

  • Patent number: 4111506
    Abstract: A rail is tiltably mounted on a crank arm at one end of the rail or the rail is hung at both ends on pivotal link hangers. In the case of the crank arm, the rail extends from the attached end over center to the opposite side of the crank arm so that when the crank rises or lowers with the attached end of the rail, the other cantilevered end of the rail lowers or rises in the opposite direction to tilt the rail. In the case of the pivotal link hangers, the distance between the pivot points at the hangers is greater than the distance between their connection to the rail so that when one link extends downwardly to lower that end of the rail, the other link extends outwardly to raise the other end of the rail to cause the rail to tilt. A trolley rolls on the rail and supports a container, such as a wastebasket. The apparatus may be mounted on a desk and a wastebasket may be carried by the trolley. By tilting the rail the trolley rolls to the lower end of the rail and carries the wastebasket with it.

  • Patent number: 4103896
    Abstract: The golf grip training apparatus gives a signal to the golfer when the grip of his off-target hand interferes with the grip of his target hand in the swing of the club. A force sensitive element is located in the position of at least the middle fingers of the off-target hand. A signal device is controlled by the force sensitive element to emit a signal when the force exerted by the off-target hand exceeds minimal force. The signal advises the golfer that his off-target hand has exerted more than minimal force and thus has interfered with his target hand in the swing of the club. When no signal emits during the swing, the golfer is advised that his off-target hand has not exerted more than minimal force and thus has not interfered with his target hand in the swing of the club.

  • Patent number: 4071167
    Abstract: An apparatus for dispersing substances into one another by subjecting them to shear forces between a rotating platen and a stationary or counter-rotating platen which have opposed work surfaces interfaced and forced toward engagement with one another. An oriface leads through one platen to the other platen. A pump forces an agglomerate of substances through the channel and radially outwardly between the platens during relative rotation of the platens. The agglomerate is subjected to shear forces as it moves radially outwardly between the platens to disperse the substances to one another. The mutually dispersed substances emit at the periphery of the platens and are collected in a trough.

  • Patent number: 4067484
    Abstract: Power dispensing apparatus for dispensing measured increments of colorants, lubricants, stabilizers, etc., into casting, paint, and synthetic resin, etc., industrial processes having a block with a displacement chamber and bi-directionally air powered valves controlling inlet-supply and outlet-use ports in conjunction with a displacement rod reciprocating in the chamber. A case is connected to the block and has a reciprocating piston attached to the rod. Air pressure is fed to the case to reciprocate the rod in one direction and from the case to opposite positions on the air powered valves to cause one to open and the other to close to effect dispensing an increment of material to use. Air pressure fed to the case to move the piston and rod in the other direction is also fed to the air powered valves to close the one and open the other to draw in material from supply. An adjusting screw limiting the stroke of the piston renders the apparatus variably adjustable as to the quantity dispensed.

  • Patent number: 4045108
    Abstract: The retainer has a base plate lying between the dual sockets of an electric outlet. The base plate is mounted over the outlet shield and secured with the same screw which secures the shield. Paired flanges extend outwardly from the base plate and a pair of spaced spring legs with feet extend from each of the flanges at an angle. The legs lie parallel to the shield and the feet extend normally inwardly into spring pressed contact with the shield. A plug is inserted into a socket by manually flexing the feet and legs outwardly. Upon plug insertion and release of manual flexing, the legs spring back into engagement with the plug urging it toward inserted position with the feet out of contact with the shield. When one plug is inserted, the unused pair of legs and feet bear against the shield and off-set the levering-twisting at the base plate and screw and aid in exerting force against the inserted plug. When two plugs are inserted, one off-sets the other.

  • Patent number: 4037847
    Abstract: A golf training apparatus having a foot platform which is rockable from side-to-side on a rocket oriented on the long end-to-end axis of the platform. The platform operates on an attached or unattached base and a signal device is attached to the platform to indicate platform rocking movement by the emission of a signal. The platform tilts inwardly toward center in the ball address position. The player stands with his golf shoes on one or two platforms with his body on center and the platforms at ball address position. By not shifting his body away from the target on a proper backswing, the force in his off-target foot remains centered, the off-target platform is not tilted and no signal emits. By subsequently shifting his body toward the target on a proper downswing, the applied force in his target foot moves to the outside of his foot, tilts the platform to the opposite side (IE) outwardly toward the target, and a signal emits.

  • Patent number: 4030860
    Abstract: A fluid metering apparatus having paired cylinders, pistons and piston rods. The piston rods are connected to a lever or walking beam which, when pivoted at its center equidistant between the rod connections provides controlled equal travel distance and rate for the pistons providing equal cubic displacement in the cylinders. When the beam is pivoted off-center closer to one rod connection than to the other, the piston on the closer rod travels a shorter distance at a slower rate than the other piston providing unequal cubic displacement in the cylinders. In either case the quantities are measured proportionally to one another in the same period of time. The system is controlled by air cylinders and valves actuated by the reference piston rod. Telltale indicators are carried by the air cylinders to visually show any malfunction at each air cylinder individually. Automatic system operation is provided for continuous metering.
