ABSTRACT:
A chain of the trolley conveyor type has T-headed pins and links with slots at each chain joint for assembly and disassembly wherever desired. The slots of the center link are slightly restricted to prevent disassembly when not desired, as in handling the chain. Also, U-shaped center link bushings in which the pins are turnable and with which the pins may pivot for chain side-flexing provide a restriction to assembly and disassembly and particularly the latter so that unintended disassembly is prevented.
