This invention relates in general to an improved hand tool, and in particular is directed to a novel-locking wrench. One object of the invention is to provide, in a wrench having relatively adjustable jaws and initial adjusting mechanism therefor, a locking device operative to releasably clamp the work 'between the jaws and simultaneously secure the adjusting mechanism against change of position. A further object of the invention is to embody the same in a "crescent" type wrench wherein the initial adjusting mechanism includes a rack on the movable jaw and a worm wheel turnably mounted in the handle, said locking device functioning to urge the worm wheel axially in the direction of closing movement of said jaw whereby to releasably clamp the work, in the wrench and set up high resistance to turning of said worm wheel. A further object of the invention is to produce a simple and inexpensive device, and yet one which will be exceedingly effective for the purpose for which it is designed.
