ABSTRACT:
A nut wrench is constructed to function like a ratchet wrench by forming one of the two jaw members as a slideway which diverges from the gripping face of the other jaw member toward the front of the jaw, mounting on the slideway a slide member which has the second gripping face, and lightly spring-biasing the slide member rearwardly to a normal position. The parts are so proportioned that, when the wrench is engaged with a nut, reverse rotation of the wrench displaces the slide member forwardly until the span across the jaw members is sufficient to override the angles of the nut, after which the spring returns the slide member to its normal position.
