Abstract
An improved hoisting hook or becket including an upper body member having an eye in the upper portion for receiving a cable, hook or the like for lifting the becket and any load attached to it, the body having spaced apart openings near the bottom edge, a lower U-shaped shank member having ends which are in a common plane and having openings near each of the ends, the openings in the shank and body being substantially equidistant and a pair of links each having parallel side plates and parallel horizontal upper and lower pins, the lower pins of each link being received in the openings in the shank and the upper pin of one of the hooks being received in the first opening in the body so that the shank is pivotal relative to the body, the second opening in the body having open communication through the top of the body member and providing means so that the upper pin of the second link can be slidably moved into and out of the second opening, the dimensions of the body, shank, hook and links being arranged such that there is normally a small space between the ends of the shank and the lower surface of the body and wherein the shank can be moved upwardly and laterally in the direction towards the body second opening. The second link can be swung out of engagement with the body to permit the shank to be opened. When a weight is placed on the hook the shank is moved downwardly relative to the body and in such position the second link cannot be disengaged from the body.
