Abstract
A chain assembly for easy removal and replacement of a module for supporting and carrying objects along a path parallel to chain movement. The chain has a pin link with a hollow pin adjacent an extended pin. A module having cylindrical shaft and perpendicular plate is inserted into the hollow pin so that a hole in the plate fits over the extended pin. The module is secured to the chain by insertion of a cotter pin into a hole at the end of the extended pin.
Claims19
A chain assembly having a plurality of adjacent roller links joined together by a plurality of pin links, each pin link having a first pin plate rigidly attached to first and second pins for insertion through separate adjacent roller links and each pin link having a second pin plate for securing adjacent roller links onto said pins while allowing movement of said roller links in the plane perpindicular to the pins, wherein at least one pin link has a hollow first pin, wherein said hollow first pin has larger diameter than said second pin, and a support means inserted in said hollow first pin for supporting objects and for carrying objects along a path parallel to chain assembly movement, the support means comprising a pintle for insertion into said hollow first pin, carrying means connected to said pintle for carrying objects and the support means further comprising a module pin plate rigidly attached to the pintle for securing said pintle to the at least one pin link having the hollow first pin.
A roller chain having at least one link adjacent pin links in a chain, said at least one link comprising:
- a first link plate having a plurality of holes;
- a second link plate having a plurality of holes;
- a plurality of bushings rigidly attached at opposite ends to the first and second link plates severally at the holes of the link plates;
- at least one of the bushings comprising a large bushing having a diamater larger than diameters of other bushings in the chain;
- at least one pin adjacent the large bushing having a length longer than pins in adjacent pin links, said pin extending laterally from the chain and means on an extended end of the pin for securing a carrier to the chain, and a carrier having a plate with an opening for receiving the extended pin and having a carrier pintle extending outward from the plate laterally of the chain and having means to secure the plate and the carrier pintle to prevent rotation with respect to the chain.
