Patent ID: 7024971

Claim:
A wrench comprising a pair of jaws disposed on a handle, the jaws being spaced to define an opening for a workpiece, a first one of the jaws defining a stationary workpiece engaging surface adjacent the opening, and a plate defining a second workpiece engaging surface adjacent the opening, the plate being movably mounted to a second one of the jaws to allow selective movement of the plate relative to the stationary workpiece engaging surface between: a) a first state in which the plate is immobile with respect to the first jaw so that rotation of the handle in a first direction causes the plate and the first jaw to grasp the workpiece between the respective engaging surfaces and turn the workpiece in a first direction, and b) a second state in which the plate is movable with respect to the first jaw so that rotation of the handle in a second, opposite direction causes the plate to move in multiple directions with respect to the first jaw to enable the respective engaging surfaces to slide over the workpiece, thereby allowing the workpiece to remain stationary, the plate being mounted for the selective movement between the first state and the second state in response to rotation of the handle.
