Abstract
564,834. Lifting - dogs. RIDDELL, A. G. Dec. 27, 1942, No. 18380. [Class 78 (iv)] In a plate-lifting device comprising a top piece adapted to be attached to the crane hook or lifting element and a body with limited vertical movement relative to the top piece and carrying a plate-gripping jaw connected to the top piece so that the jaws are closed by the weight of the body, the body is slotted to receive the plate and at its lateral edges is of channel formation to form guides for the links which operate the jaws. The Figure shows a body consisting of spaced U- shaped plates 1 pivoted to the jaw levers 4, pairs of which are arranged on the surfaces of the plates. The levers 4 are coupled by links 5 arranged between the plates 1 to the top piece A. The top piece may be secured to the body plate 1 by a pin to render the jaws inoperative in their open condition.
