ABSTRACT:
An improved adjustable socket for use with a ratchet wrench drive handle to loosen or tighten bolts, nuts and other threaded workpieces, is comprised of a hollow cylindrical casing having a passive end adapted to receive a wrench handle protuberance, an opposing work end adapted to fit about a workpiece and a sidewall interconnecting such ends with one another and defining a cavity therebetween. A plurality of uniformly spaced apart through-openings are provided in the casing sidewall between the opposing ends thereof and a cylindrically shaped gripping member is pivotally mounted along a vertical eccentric axis thereof within each through-opening so as to be selectively moveable into and out of the casing cavity. In use, the adjustable socket is mounted onto a wrench handle and positioned about a threaded workpiece. An adjustment ring is then rotatably moved, say downwardly, so that a beveled surface thereof contacts a corresponding beveled surface of each gripping member and causes each gripping member to radially move inwardly into the casing cavity whereby a convex work face of each gripping member contacts the periphery of the workpiece. Upon application of torque to the wrench handle, each work face is continually urged into intimate gripping contact with the workpiece so as to drive it in a desired direction. Upon release/reversal of the torque force and upward movement of the adjustment ring, each gripping member is urged, via a biasing means, radially outwardly of the casing cavity so as to disengage from the workpiece.
