ABSTRACT:
A compact ratchet mechanism for box end or similar wrenches comprises a driver ring with cam teeth on one face, a driven ring rotatably confined in the driver ring and having the wrench configuration in its interior, and a pawl ring rotatably supported on the driven ring. The pawl ring has cam teeth cooperating with the driver cam teeth, and the pawl ring and driven ring have shorter interfitting teeth. The cam teeth have sufficient rise to hold the shorter teeth engaged when the driver ring is rotated one way, and to allow the shorter teeth to disengage when the driver ring is rotated the other way.
