ABSTRACT:
A guide clamp is disclosed which includes a clamping jaw at one end of a guide bar. An opposing shifting jaw is slidably carried on the guide bar to permit a workpiece to be embraced by the jaws. The guide bar is a flat, rectangular channel member open at the undersurface which engages the workpiece surface. The jaws, extended below this undersurface engage the opposite sides of the workpiece, such as a board, with the shifting jaw being shiftable and lockable in the channel at a jaw-engaging position and with the clamp jaw being shiftable in the channel a short distance by lever action to lock the clamp onto the workpiece. When so mounted and locked upon a workpiece, the guide clamp may be used as a clamp, a marker guide or a tool guide. Suitable guideways to guide and hold tools, jegs and the like may be provided on the guide bar.
