ABSTRACT:
A selectively removable block and pusher assembly is provided for a feed chain comprising a plurality of links. At least some of the links are provided with a pair of parallel spaced pins extending transversely therefrom from which the block and pusher assembly is removable. Each block and pusher assembly comprises a block and a pusher removably attached to the block. The block includes a first pair of parallel, spaced bores extending therethrough parallel to its transverse axis for receiving the pins extending from the links, and a retaining member positioned in the block for releasably retaining circumferential grooves formed adjacent the free ends of the pins. The retaining member comprises a flexible and resilient U-shaped spring clip having a pair of spaced legs received in a second pair of spaced bores in the block and an intermediate portion which releasably retains the circumferential grooves in the pins.
