The invention relates to a wrench, and more particularly to the class of quick adjusting wrenches. The primary object of the invention is the provision of a wrench in which the adjusting screw, may be entirely disengaged from the toothed rack on the shank of said wrench, whereby the movable jaw may be freely slid upon said shank for the quick adjustment of the movable jaw, so that subsequent thereto accurate adjustment may be had for the gripping of a nut or other part to be turned by the wrench. Another object of the invention is the provision of a wrench in which its movable jaw may be freely slid on the shank of the wrench and accurately adjusted for the gripping of the work to be turned by the wrench. A further object of the invention is the provision of a wrench in which a locking pin is arranged, whereby the adjusting screw may be engaged with and disengaged from the toothed rack on the shank of the wrench for the quick and accurate adjustment thereof. A still further object of the invention is the provision of a wrench which is simple in construction, thoroughly reliable and efficient in operation, and inexpensive in manufacture.
