Abstract

See full text

In a ratchet wrench of the type having a head which is manually rotatably shiftable for reversing the driving direction or torque-transmitting mode of a socket carried by the wrench and in which the head is also manually depressible to effect release of a socket carried by a drive stud of the wrench, an improved control bar or lever for rotating the head of the wrench to effect socket drive reversal. The control bar surmounts and is attached to the head for pivotal manipulation thereof. An integral end portion of the control bar extends radially beyond a bounding periphery of the head to provide increased torque forces and enhanced ease of manual annular shifting of the head and of the socket drive direction control components coupled thereof. A free end of the control bar is spaced from the wrench to permit depressing the head manually to effect the release of a wrench-carried drive socket.
