Abstract:
A wrench comprisinga pair of jaws disposed on a handle, the jaws being spaced to define an opening for a workpiece, a first one of said jaws having an elongated hole disposed therein,a pair of plates respectively mounted on the jaws, each of the plates including a workpiece engaging surface adjacent the opening, anda pin mounted on a first one of the plates, the pin and the hole being arranged to enable selective relative movement of the plates between:a) a first position in which the pin is not disposed in the hole and the plates are immobile with respect to each other so that rotation of the handle in a first direction causes the plates to grasp the workpiece between the engaging surfaces and turn the workpiece in the first direction, andb) and a second position in which the pin is positioned in the hole and the first plate is pivotable with respect to a second one of the plates in a direction defined by the elongated hole so that rotation of the handle in a second, opposite direction causes pivoting of the first plate and allows the engaging surfaces to slide over the workpiece, thereby allowing the workpiece to remain stationary.
