ABSTRACT:
A clamp having slip plane positioning enables a clamp nose and an attached pressure foot which are initially non-permanently attached to the clamp arm to be brought into a final predetermined coordinate position before the clamp nose is fixedly attached to the clamp arm. The clamp nose has the pressure foot mounted at one end. An open-ended slot is formed at the other end of the clamp nose and slidingly engages opposed side walls of one end of the clamp arm. In one embodiment, a fastener threadingly extends through a portion of the clamp nose surrounding the slot into engagement with the clamp arm to non-permanently attach the clamp nose to the clamp arm. In another embodiment, aligned bores and slots are formed in adjoining surfaces of the clamp nose and the clamp arm and receive fasteners therethrough to non-permanently mount the clamp nose on the clamp arm. The clamp nose and the pressure foot attached thereto are positionally adjusted with respect to the clamp arm at final assembly to bring the pressure foot into a predetermined coordinate position before the clamp nose is fixedly secured to the clamp arm.
