Description:

The patent includes a quick-adjust movable jaw, and a pivoted, rotating handle. The objective is to combine functions of a "monkey wrench" and "speed wrench."

A known brass example may be a prototype; the adjustment means for the movable jaw differs from the options shown in the patent drawings.
