ABSTRACT:
A clamping device adapted for use in combination with a vise to maintain a workpiece in fixed relation to the vise when being worked on. The clamping device includes a plate member which is forced downwardly on the workpiece which is being held between the jaws of the vise. The plate member is threadedly mounted to the opposing vise jaws through a pair of transversely opposed screw members. A pair of thumbscrews or lock washers threadedly engage the screw members and interface with an upper surface of the plate member to force it against the captured workpiece.
