The vise has a brake mechanism and an offset mechanism associated with one slide so that workpieces can be engaged and released sequentially. If the brake mechanism is not activated, the two movable jaws are moved simultaneously. With the brake mechanism engaged, one movable jaw is moved to position first and then the movable jaw having the brake and offset mechanisms connected therewith is subsequently moved into position. When the workpieces are to be released, the second movable jaw is first retracted the offset distance and then the first movable jaw must be completely retracted prior to any subsequent movement by the first movable jaw.

A head of a fastener is slid into a wider portion of the slot with the shank of the fastener extending out one of the narrow slot portions, to extend from a first of the two faces of the jaw. The second, opposite face may be used for clamping. The jaw plate can be reversed so that the shank of the fastener extends from the narrower slot in the other of the jaw plate faces, to permit using the first face for clamping. Either one of the jaw plate faces can be used for clamping a workpiece by reversing the jaw plate and having a reversible fastener in the mounting slot or slots to secure the jaw plate to a jaw or mounting member.

Abstract: A vise with first and second movable jaws slidable on elongate ways on a base. An actuator shaft extends longitudinally of the base and has first and second reversely threaded portions threadably engaged with the respective first and second movable jaws. A releasable retraining device cooperates between the base and the second jaw to restrain slidable movement thereof. The actuator shaft is axially floatable supported relative to the base and when rotated in one direction causes the first jaw to move in a first direction along the ways. The restraining device prevents slidable movement of the second jaw so that rotation of the actuator shaft causes the shaft to be axially displaced due to its threaded engagement with the second jaw, and this increases the movement rate of the first jaw due to its threadable engagement with the actuator shaft.
