Abstract:
A trolley or carriage assembly for conveyors, including overhead and in-floor conveyors, in which the inner race of a wheel assembly, a shield or seal for the wheel, and a support for supporting a work piece to be transported by the trolley or carriage assembly are simultaneously locked against rotation with respect to each other and a supporting and retaining shaft by the non-circular outer circumference of the shaft and corresponding non-circular apertures of the inner race, shield or seal and support. Preferably the shaft is a hexagonal, headed bolt or rivet which may include a relubrication passageway for use in closed, sealed wheels. The assembly provides better load distribution, easier assembly in and disassembly from conveyors, and longer, more durable and wear-resistant operation, especially with stamped, sheet metal trolley brackets.
Abstract:
An endless conveyor chain is a sequential assembly of block links formed of a polymeric material, interconnected by thin fleixble links of undulated shape, formed of either metallic or polymeric material, which are easily capable of flexing through their thicknesses, making it possible for the chain to negotiate lateral turns in the conveying run by producing edgewise flexure in the links. Large bearing stresses, which normally result in applications where chain joint lateral articulation occurs in nonlinear chain travel, are minimized or eliminated since the requisite lateral movement is allowed by flexure in the thin links away from the chain joints.
Abstract:
A cleat member for the conveying surface of a conveyor that moves in one or more planes. The conveyor surface may be formed of a plurality of flat, flight attachments and one or more cleat members positioned between spaced flight attachments, all being secured to drive chain. The cleat members include shoulder means permitting the cleat to push as well as to, in certain circumstances, slip under articles such as cartons carried by the conveyor. The shoulder means may also be formed on flat, belt type conveyor surfaces to provide a similar slip cleat in accordance with the invention.
Abstract:
A conveyor of the endless chain type passing around two or more sprockets provided with means for compensating for the chordal action which ordinarily occurs as a chain passes around its associated sprocket. The chain is composed of links having overlapping portions pivoted together by pins which have eccentrics associated therewith that have sprocket-engaging surfaces. As the links move onto and off the sprockets, these eccentrics are controlled to rock relative to the pivot pins to vary the pitch of the successive links, which serve to keep the runs of the chain moving at a constant speed.
Abstract:
A chain conveyor has feed rollers loosely fitted over chain rollers for conveying articles thereon at a speed higher than that of the chain rollers being driven on a rail means. The feed rollers have a diameter larger than that of the chain rollers such that the feed rollers, upon corotation with the chain rollers due to frictional engagement therewith under the weight of the articles, have a peripheral speed greater than that of the chain rollers. The articles can be stopped or accumulated at a desired position while allowing the feed rollers to be underrun without substantial slippage against the articles by rotating in a direction opposite to the direction of rotation of the chain rollers being continuously driven.
Abstract:
An apparatus is provided for electrically stunning animals to be slaughtered. Said apparatus comprises electrodes which are pivotable about horizontal axes and, in their initial position, extend downwardly into a V-shaped passageway formed between two parallel endless conveyors. Said electrodes are mounted within a frame which is movable in a direction coinciding with the direction of movement of the conveyors. Said frame is connected to a driving mechanism which is adapted to move the frame with substantially the same speed as the speed of the conveyors and which starts its movement upon closure of the circuit between the electrodes by an animal to be stunned.
Abstract:
An extractor bar assembly for use in a frozen stick-mounted confection forming machine, adapted to remove the frozen stick-mounted confection products from their associated molds by engaging each stick in a substantially vertical direction using a cam locking mechanism. The cam locking mechanism is comprised of a plurality of tubular segments flotably mounted on a support rod which in turn is movably mounted within a V-shaped trough forming the body portion of the extractor bar assembly. The individual sticks enter through an opening provided along the bottom of the V-shaped trough and are held within the extractor bar by a cam locking mechanism. To release the individual sticks from the extractor bar, a release mechanism is provided with enters the trough through an aperture located on the bottom edge of the extractor bar and displaces the cam locking mechanism in an upward direction.
Abstract:
A document transport belt for use in an automatic document handler in an electrostatographic copying machine is provided, which is made from an ethylene propylene diene rubber. The document transport belt of the invention has a stable coefficient of friction, high resistance to ozone attack, superior whiteness stability, high resistance to abrasion, and outstanding mechanical stability so that it does not require the frequent tension adjustment after operating under machine conditions for a period of time.
Abstract:
A roller chain conveyor having wire cross flights and attachments for releasably mounting said cross flights on the chain to provide a conveying surface. The attachment has at least one groove therein to receive an extended portion of the cross flight. The attachments may also be used in conveyors having multiple roller chains therein.
Abstract:
Apparatus is provided for loading poultry from a rearing house into a series of hen-coops arranged in vertical rows on a transport vehicle. The apparatus includes an elevator conveyor which takes the animals from an assembly enclosure to a vehicle movable transversely of the elevator conveyor. This vehicle comprises a first horizontal conveyor extending parallel to the longitudinal axis of the vehicle and arranged to receive animals from the elevator conveyor, an adjustable-inclination conveyor disposed alongside the first horizontal conveyor, a second horizontal conveyor disposed transversely to the first horizontal conveyor and arranged to transfer animals from that conveyor onto the adjustable-inclination conveyor, and a pneumatic forced-delivery unit located transversely at the output end of the adjustable inclination conveyor.
