ABSTRACT:
A unique and novel adjustable wrench including a fixed handle (10) and handle jaw (10C), a movable handle (12), pivoting about a dog (16) and assembled to a slide (18) by a pair of links (24). The wrench features parallel jaws and provides a significant mechanical advantage by multiplying and transferring the operator's force to an object to be held and/or turned. A set of unique holding plates (40 & 42), in the shape of an `U`, attached to fixed handle jaw (10C) and sliding jaw (18) by means of mounting bolts (44 & 46). Holding plates (40 & 42) may be removed and/or reversed, this enables the wrench to be adapted to various work situations including rough plumbing, soft metal, and reverse thread.
