Title: Chain attachment structure

Abstract: A chain attachment structure interconnects the end of a chain to the takeup drum of a winch or hoist so that the chain load is applied directly to an integral part of the drum even if the chain is fully unwound. A recess extends inward from the periphery of the drum and includes a pair of spaced walls. A lug integral with one wall extends toward the opposite wall. The space between the lug and the opposite wall defines a path for inserting a chain link into the recess and over the lug. A keeper inserted into the path prevents removal of the link from the lug.
