Torque clutched reversible ratchet wrench

Abstract

A two sided or headed ratcheting driving wrench. Each side or head has a rotatable receptacle constrained to rotate in only one direction by interengaging teeth formed in the receptacle and in its housing. Both sets of teeth may be pointed or rounded. In one direction, torque locks the receptacle to the housing, and thus drives a tool such as a screw driver blade or a socket. In the other direction, torque causes the receptacle to disengage from the housing. Thus, conventional, intermittent one way rotation is assured. The receptacle and its surrounding chamber formed in each tool head are dimensioned and configured to assure engagement between receptacle and head when placed under torque in one direction. The wrench has a lever or handle which has a significant portion of its length offset from linear to allow for working in tight quarters. The receptacle has a square hole formed therein, for receiving a driven tool. The driven tool comprises a square block cooperating with the square hole of the receptacle, and has two oppositely oriented blades, sockets, or other tool elements. In another option, the square block is separate from the driven tool, to allow for versatility. In a further option, a fastener is formed integrally with the receptacle. Optionally, the drive system has provision for limiting torque acting on the driven fastener. Direction of operation is reversed by inverting the wrench. No adjustment of a lever is required.
