ABSTRACT:
An improved vise includes a base, a journal housing, and fixed and movable clamping jaws. The housing includes passageways for a worm gear and a clutch means. By appropriate manipulation of a control for moving the movable jaw, an actuator within the housing may be rotated so as to effect the engagement and disengagement of the clutch means with the worm gear. When the clutch is engaged, the vise may be tightened in the usual manner of rotating the control. When the clutch is disengaged, the movable jaw may be moved quickly by the longitudinal movement of the control without rotation.
