Abstract
A simplified, impulse-type pulling and installing tool for appliances such as electrical connector elbows is provided which in use generates a sharp impact force to facilitate quick, safe elbow manipulation even under electrical load, thereby reducing the probability of flashover. In preferred forms, the tool includes an elongated rod having workpiece-engaging apparatus adjacent one end thereof, with tubular hammer means telescoped over the rod and reciprocably slidable along a portion of the length thereof. The hammer includes structure defining a pair of hammering surfaces respectively located adjacent the opposed ends of the hammer, and the rod is moreover provided with anvil means secured thereto and oriented for engagement by the hammering surfaces when the hammer is slid along the rod. A pair of such hammering surfaces are provided, which are cooperatively oriented relative to the hammering means, so that fore and aft impact forces can be developed along the length of the rod as desired. In particularly preferred forms, the anvil means is secured to the rod within the bore of the hammer means, and presents a pair of opposed anvil surfaces respectively engageable by corresponding, internal hammering surfaces on the hammering means.
