ABSTRACT:
A gripping device including a fixture having a working surface and at least one hole. A stop rises above the working surface of the fixture. A threaded fastener is provided to screw into the at least one hole in the working surface of the fixture. A gripping member is provided such that a work piece can be held in a stationary fashion between the gripping member and another element such as a stop. The gripping member includes a conical bore and an elongated bore. The elongated bore is a through bore in that it extends through the entire thickness of the gripping member. The conical bore extends through only a portion of the thickness of the gripping member. The fastener extends through both the conical and elongated bores. The elongated bore is offset towards the gripping face of the gripping element thereby enabling the gripping member to travel to an from the work piece a greater distance than gripping members employing a centrally located circular through bore. In addition, the elongated bore restricts the travel of the gripping member in a direction transverse to the direction of travel to and from the work piece.
