摘要： A spring-biased plunger, preferably if not always assisted by fixed jacks, supports a workpiece to be mechanically operated on forcibly by a metalworking or like machine. The plunger is spring-urged upwardly, then supported in an upwardly adjusted position by clamping elements of a clamp device which are actuated toward one another in opposite horizontal directions by manually operated screw means. As thus clamped in a positive preliminary way, a wedge device, as coordinately operated through a toggle type member in synchronism with the clamp device, comes into action beneath the plunger to rigidly sustain the same.
