ABSTRACT:
A vise structure has a control handle cooperating with a two-part guide rod means, including respective inner and outer rods mounted telescopically relative to each other. The handle is rotatably supported on the frame and has a limited longitudinal movement thereon. In one longitudinal position, the handle is coupled only to the inner rod for rotation in unison; and the inner rod is linked to a pair of pivotably-mounted vise jaws arranged to move towards and away from each other transversely of the vise structure. In a second position of the handle, both the inner and outer rods are rotated for movement of the pivotably-mounted vise jaws and, respectively, for longitudinal movement of a transversely-arranged elongated vise jaw from one end of the structure to its other end. In a third position of the handle, only the outer end is rotated for movement of only the elongated vise jaw. The vise structure is adapted for a work bench and is arranged to clamp various irregularly-shaped work pieces therein.
