Abstract

Adjustable socket (10) for rotatively driving bolts and nuts including a plurality of jaws (18) mounted on a rotatable driver (16) for quick action adjustment between fully opened and fully closed positions upon rotation of an adjuster (22) no more than one revolution. Each jaw has an inclined camming surface (28) that is slidably engaged by a jaw positioner (20) upon axial movement thereof in response to rotation of the adjuster so as to provide radial adjustment of the jaw positions. A spring (30) biases the jaws in an outward radial direction into engagement with the positioner. In one embodiment, the jaw positioner comprises a sleeve (20) which preferably has apertures (62) that receive the jaws, and the adjuster has a 360` helical locking surface (26) that cooperates with a 360` locking surface (24) on the driver in an axially opposed relationship to provide locking action and jaw adjustment. Another embodiment of the socket includes a unitary sleeve having a jaw positioner end that slidably engages the camming surfaces on the jaws and an adjuster end that is rotatably adjustable to adjust the jaw positions under the control of axially engaged locking surfaces on the driver and the adjuster end of the sleeve. Combined radial and axial jaw movement upon adjusting prevents jamming in both embodiments.
