Abstract

A rugged sturdy workpiece positioning mechanism that effectively and efficiently positions and holds at least two workpieces for further operations is provided. The mechanism includes a main support which is slidably connected to a first workpiece and a housing assembly which is affixed to the main support and extends above and engages the second workpiece. The housing assembly includes two side plates, a cam with a handle rotatably attached to the sideplates, a ratchet to lock the cam into a fixed position and a load bearing surface actuated by the cam and slidably received between the side plates. The edge of the cam abuts the load bearing member. When the cam is rotated in a predetermined direction, the distance between its axis of rotation and the load bearing member increases driving the load bearing member downward. The load bearing surface engages the workpiece and forces the second workpiece into a desired position relative to the first workpiece. Once the joining operation is completed, the mechanism is slidably detached from the workpieces.
