发明名称 Double ended adjustable wrench
摘要 A double ended adjustable wrench for turning nuts, bolts, pipe and the like. The wrench is generally elongated in the manner of a conventional adjustable wrench, but the body of the wrench is made up of two substantially identical sections which are connected together for relative lateral movement toward and away from each other. The opposite ends of each section are appropriately shaped so that they cooperate with each other to define jaws which open and close as the two body sections move laterally. A mechanism is provided for movably connecting the two body sections together and for adjustably moving them relative to each other in order to open the jaws in a parallel manner a desired amount within predetermined limits. The jaws at one end are larger than the jaws at the other end, and at least one end of the wrench includes serrated jaws, so that a single wrench constructed in accordance with the principles of the invention replaces at least two if not three standard adjustable wrenches.
