ABSTRACT:
A wrench with torque augmenting means consisting of an output socket wrench which utilizes a ratchet arrangement and which includes an input cog that is adapted to receive an external drive tool. The input cog constantly rotates under the influence of the external drive tool and a camming surface formed on the arm of the input cog coacts with a cam follower surface on the drive plate of the output to move the drive plate. A spring within the housing of the apparatus connected to the drive plate will cause the drive plate to return to its initial position where the action of the camming surface of the rotating cog arm from the input cog can then repeat its function. Rotary movement of the output in one direction is accomplished during the oscillation of the drive plate by means of the ratchet positioned within the drive plate.
