ABSTRACT:
A ratchet wrench with unitary floating pawl. The pawl has arcuate sides which rest against arcuate walls in the wrench body permitting rotation of the pawl in the body when a detented flat reaction bar slidably contained in the wrench body is positioned against one of two projecting pads on the pawl. The contacted projecting pad on the pawl restrains the pawl from rotation in one direction and the clearance of the second pad with the reaction ar permits the pawl to ratchet in the other direction. Sliding the detented reaction bar changes the direction of wrenching and ratcheting. An efficient, strong, thin-walled body for effective use in close quarters is the result.
