ABSTRACT:
A hand tool, such as a screw driver, with a handle connected to the tool element thereof so that when the handle is turned in one direction, there is a positive driving action but when it is turned in a reverse direction, the handle is free to rotate relative to the tool element. The connection is made by means of a coil spring mounted on a driver shaft member and a driven shaft member, which are connected non-rotatably to the respective handle and tool element. The shaft members are in axial alignment but relatively rotatable, and a coil spring or helix is disposed concentrically around their aligning axes in frictional engagement with both members so that when one member is rotated relative to the other in one direction by the handle, the spring more firmly engages the shaft members to connect them together, to drive the tool element, and when the direction of rotation of the handle is reversed, the axially-aligned shaft members are released by the spring to permit relative free rotation of such members, and, thereby, free reverse movement of the handle relative to the tool element.
