ABSTRACT:
A tool for safe, manual shifting and manipulation of energized lines is provided which finds special utility in mines or other close areas where conditions of moisture and the like make it mandatory that electrical equipment be handled with great care. The tool includes an elongated, insulative rod having, adjacent one end thereof, a pair of spaced, opposed, fixed, hook-like, spiral, cable-engaging fingers. In use, the fingers are placed astride an electric cable or the like and the rod is rotated axially so that the fingers pass under and cooperatively engage and capture the cable therebetween, thus permitting easy shifting and movement of the cable. Particular features of the tool include the complete elimination of any mechanical moving parts, and the special configuration of the cable-engaging fingers permitting easy lateral shifting of a cable without fear that the cable will become disengaged and fall free of the tool.
