ABSTRACT:
A quick-adjust wrench utilizes a sliding jaw which slides with a casing which straddles the wrench shank and captures therein a pawl which rides in a groove extending longitudinally in the shank. A rocker rocks against the pawl when the wrench jaws try to expand, forcing the pawl into its groove in the wrench shank with great force, securely lodging the jaw with respect to the wrench shank to prevent further expansion. This mechanism provides the wrench with infinite and instant adjustability and a very positive, play-free action.
