Patent number: 4271960Abstract: A conveyor chain and conveyors using such chain in which a plurality of elongate links are joined together with a plurality of pins and a plurality of spacers. Each pin penetrates terminal end portions of two pairs of links for chaining the links into first and second spaced apart side length portions and the links and pins cooperate for transmitting tensile stress imposed on the chain. Each of the plurality of spacers is penetrated by at least one pin and has a carrier portion projecting laterally from the chain for engaging an object to be moved with the chain. As used in certain specific conveyors, the conveyor chain includes clips for receiving and gripping rod-like axles and grippers for partially encircling a pair of objects to be moved with the chain, all as described more fully hereinafter.Type: GrantFiled: November 19, 1979Date of Patent: June 9, 1981Assignee: Taylor Manufacturing CompanyInventor: Charles Chalich

Patent number: 4142624Abstract: An apparatus for accumulating into a group a series of spaced-apart loaves of bread in a bakery conveying line comprises an entry conveyor and an exit conveyor each including a driven belt of interconnected free rollers. Upon the arrival of the first loaf at the exit end of the exit conveyor, the exit conveyor is stopped, with succeeding loaves accumulating behind the first loaf under the continued action of the entry conveyor to form a contiguous group which fills first the exit conveyor and then successive zones of the entry conveyor. As each zone is filled, a corresponding shoe is moved into engagement with the rollers passing through that zone for rotating them to counteract the movement of the entry conveyor belt and relieve pressure on the accumulated loaves.Type: GrantFiled: August 29, 1977Date of Patent: March 6, 1979Assignee: Velten & Pulver, Inc.Inventors: James J. Diver, Henry A. Heide, Basil J. Masse

Patent number: 4096937Abstract: An article transport system employs a rail assembly and a holder rotatably mounted on a conveyor. The assembly is comprised of a series of interconnected, axially-aligned, generally cylindrical members, which are relatively free to move independently of one another. Relative movement of the holder and rail assembly causes, through frictional engagement therebetween, the uniform rotation of an article mounted on the holder; the system has particular utility for transporting decorated can shells through ultraviolet curing ovens.Type: GrantFiled: January 31, 1977Date of Patent: June 27, 1978Assignee: American Can CompanyInventor: Sydney Johnstone Wallace
