This invention relates to sliding - jaw wrenches which employ a rack and pinion for adjusting the slidable jaw longitudinally upon the shank of the wrench. One object of the invention is to provide improved means for throwing the pinion into and out of engagement with the rack, so that both a quick and a close adjustment of the slidable jaw may be had. It is furthermore designed to provide an operating device for adjusting the pinion, and also to locate such operating device in convenient reach, and finally to house all of the movable parts of the device within the movable jaw. |
