Abstract
666,943. Wrenches. GORDON, W. Jan. 13, 1950, No. 924/50. Class 61 (iii). In a wrench comprising a movable jaw provided with a socket member slidable on the toothed shank 1 of the fixed jaw 2 and adjustable thereon by a worm 5, the socket is wedge-shaped, fitting loosely on the shank and provided with an arched leaf spring 12 housed between the back of shank 1 and the rear of the socket member 6 for holding the worm in engagement with the teeth. One end 12a of the spring is fixed in a recess in the inner surface of the wedge-shaped socket, the other end 12b being slidable in a second recess therein. In operation tilting of the jaw tends to tighten the grip on the nut. Quick adjustment of the jaws is made by tilting the movable jaw in the opposite direction against the action of the spring.
