ABSTRACT:
A work clamp for clamping a workpiece to a work table with a clamp member which extends and retracts to and from clamping position with a compound motion having components parallel to and normal to the table in a manner such that extensile movement of the member occurs both parallel to the table to a position over the workpiece and toward the table to clamp the workpiece against the table, and retractile movement of the member occurs both away from the table to release the workpiece and parallel to the table to clear the workpiece for removal from and placement on the table.
