ABSTRACT:
Apparatus for tensioning a cable employed for repairing deformed yieldable structures in which one end thereof has a generally U-shaped configuration. The legs of the U-shaped end is joined by a slotted cross piece to receive in locking engagement therewith a cable to be tensioned. Extending from the U-shaped end is an integrally formed threaded rod. A threaded impact tube receives the rod in threaded engagement therewith. The free end of the impact tube is suitably notched to receive a conventional air operated impact wrench. Between the U-shaped end and the impact tube is an abutment member that has a suitable opening to receive a rod. The abutment member engages a fixed upright post or bar. When the impact wrench rotates the impact tube, the impact tube engages the abutment member to maintain a fixed location longitudinally while rotating about its axis. As a consequence thereof, the rod is drawn into the tube and the U-shaped end applies a tension to the cable attached thereto. In addition thereto, the abutment member is formed with oppositely directed, aligned pivot pins, which are received for pivotal movement within suitable openings in horizontal members of the upright post so that the abutment member can pivot about a vertical axis.
