Abstract
Abstract A device for connecting wire rope to a chain and comprising a wedge means adapted to be inserted into the center of one end of the wire rope for receiving the strands of the wire rope along the outer periphery thereof, said wedge means and rope strands receiving a socket member therearound whereby the rope strands are securely clamped between the wedge and the socket member, and a connector means threadedly engageable with the socket member and having pin means engageable with one link of the chain. The threading of the connector applies force against the wedge to increase the clamping pressure against the wire rope strands. The threaded end of the wedge provides a release means for easily removing the wire rope from the wedged connection.
