ABSTRACT:
An adjustable jaw double ended wrench, where each set of jaws is gear operated. Each end wrench is adjustable, both individually and independently; the open end wrench driven by a spiral grooved shaft with beveled gears; the closed end wrench, linearly actuated by a direct driven spiral grooved shaft. At one end of the wrench is an adjustable open end wrench with a set of parallel jaws, useful in tightening or removing hex fasteners, such as hex and machine screw nuts, and cap screws. The other end, an adjustable closed end wrench for tightening or removing hex head cap screws, hex-head nuts, as well as for clutching other work. This wrench end is particularly well suited for use in areas that are blind to the user, especially in such applications as in automotive assembly and repair, ship inboard motor repair and numerous other applications of assembly and disassembly of items that may not be within the view of the user.
