  • Patent number: 4140307
    Abstract: The invention relates to a work support device in the form of a vice for rigidly supporting a work piece and enabling adjustment of the position of the workpiece to any desired angular position. The vice includes a pair of conventional vice jaws or a jig for holding the workpiece. The jaws or jig are mounted for rotational movement about a first axis when released from a locked position and also for tilting movement through 90.degree. with respect to the first axis. This movement is achieved by mounting the jaws or jig on a ball of a ball and socket arrangement wherein the socket is slotted to enable said tilting movement. The socket arrangement is mounted for rotation, when released from a locked position, in a plane normal to the plane of rotation of the jaws or jig. Thus by a combination of rotational movement of the jaws or jig and the socket arrangement as well as tilting movement of the jaws or jig the workpiece may be disposed in any angular orientation and locked in said position.
