Abstract
A two sided ratcheting driving tool. Each side has a rotatable receptacle constrained to rotate in only one direction by interengaging teeth formed in the receptacle and in its housing. A leaf spring urges the receptacle into the engaged position with respect to the housing. In one direction, the receptacle is locked 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 overcome the spring and disengage from the housing. Thus, conventional, intermittent one way rotation is assured. The receptacle has a square hole formed therein, for receiving a tool. The tool comprises a square block cooperating with the square hole of the receptacle, and has two oppositely oriented blades, sockets, or other tools. Direction of operation is reversed by using a different one of the oppositely oriented tools. No adjustment of a lever is required. The novel wrench is unencumbered by complicated internal parts, but still often reversibility and interchangeability of tools.
