The vise includes a pair of U-shaped brackets, secured to the underside of the table top, and a pair of tubular beams slidably received in the respective brackets. Each of the beams is selectively indexed to its cooperating bracket, thereby providing a "coarse" adjustment. A fixed rear vise jaw is disposed on top of the beams, transversely thereof; this rear vise jaw is secured to the brackets and abuts against the lower portion of the longitudinal front side of the table top. A movable front vise jaw is mounted on top of the beams, transversely thereof, and may be moved in a non-parallel relationship with respect to the fixed rear vise jaw for clamping tapered workpieces therebetween.

Abstract: A self-centering fixture makes use of an air actuated motor which is drivingly rotated in one direction. The fixture has a pair of levers pivoted to a base. As the motor is actuated, a cam positioned between the longer arms of each lever rotates and acts to move the longer arms apart. Thus, on the other side of the pivot, jaws on the shorter arms move towards one another to grasp the workpiece. The workpiece is released by reversely activating the motor. Since the cam is counteracted by springs which pull the long ends together, the jaws open.
