This invention relates to the rigging of wires, particularly telephone wires, between two elevated locations specifically two telegraph poles or a telegraph pole and a location on the upper part of a building. The telephone wire to be rigged is fed around the pulley of a pulley block. The block is attached to the end of the sash line which emerges from the pole top and the block carrying the loop of wire hoisted to an elevated position. The free end of the wire is then fixed to the other elevated location for example the side of a house and the wire drawn tight to its working position. By manipulation of the other end of the sash line and the wire the pulley block carrying the loop of the wire is guided into the top of the pole, down through the interior of the pole and out through the access aperture in the lower part of the pole. The wire is then secured in the pole, the loop is severed and the appropriate electrical terminations made. |
