ABSTRACT:
A vise for clamping a work piece to a workbench. One jaw of the vise is permanently mounted to the work piece and the other is carried by the threaded shaft. A block member is mounted to the workbench spaced from one jaw a distance at least as great as the dimension of the largest work piece to be clamped between the jaws. A transfer mechanism carried by the block member includes a moveable female member adapted to be moved into and out of engagement with the threaded shaft. In the disengaged position, the shaft is freely slideable in the block member to permit rapid positioning of the shaft. In the engaged position, the shaft can be turned to powerfully clamp the work piece between the jaws.
