ABSTRACT:
A protective pivot pin assembly for chains, and especially conveyor chains, and a chain assembly incorporating that pin assembly. The pin includes a collar telescoped over one end and retained by a retaining ring or other securing member. The collar has a recess which receives the retaining ring therein when the collar is urged against the ring by chain links assembled on the pin. When extended, the combined widths and thicknesses of the links hold the collar over the ring to protect the ring and prevent removal of the ring and premature disassembly of the chain. When entirely relaxed, the chain may be collapsed, allowing the collar to be slid back and the ring to be manually removed.
