ABSTRACT:
A shears coupling, particularly for interconnecting two load supporting members, such as a looped cable and a chain, by the aid of a mating coupling member, comprises a pair of two-armed levers which are rotatably interconnected by means of a common pivot. Each lever has an arcuate shank, which is located substantially in the same plane as said common pivot and has a free end which, when the shears coupling is in its closed operative position, overlaps the free end of the other arcuate shank for forming a substantially closed eye. The other arm of each lever has at least one lug, which projects, preferably radially, with respect to the pivot and is provided with a through opening, which substantially registers with the respective openings of the other lugs in said closed position. The levers are locked in the closed position of the shanks by means of a pin or bolt which is introduced through said openings and interconnects the shears coupling with the mating coupling member, which has a number of similar apertured lugs which have been interlaminated with the lugs of the shears coupling, by passing through all said openings.
