Abstract
A tool for turning a screw, nut, bolt or other rotatable workpiece includes a bottom housing carrying a workpiece engageable part and, above the housing, a handle engageable by the hand of a user. The handle is axially and angularly shiftable relative to the housing and is angularly connectable to the housing through both a torque spring and through sets of angular stops on the housing and on the handle which stops are brought into and out of engagement with one another as the handle is shifted axially relative to the housing. The tool may be used as an ordinary screw driver or wrench whereby hand torque is transmitted directly from the handle to the housing, as a torque measuring tool whereby hand torque is transmitted from the handle to the housing through the torque spring, and as a preloaded tool whereby a given amount of torque is loaded into the tool prior to application to the workpiece and then, after application of the tool to the workpiece, is released and used to rotate the workpiece without the handle being rotated by the user.
