ABSTRACT:
An apparatus for increasing the range of movement of a clamp assembly of a sewing machine in two directions, one being opposite the other. The apparatus generally comprises a first tripping member interconnected and movable with the clamp assembly of the sewing machine and having a first tripping portion which is engageable with a first limit switch of the sewing machine. A second tripping member is interconnected with the first tripping member and has a second tripping portion which is engageable with the second limit switch. Generally, the second tripping member is movable relative to the first tripping member between first and second positions. The first position corresponds with the second tripping portion being positioned within a tripping zone for tripping the second limit switch, and the second position corresponds with the second tripping portion being positioned out of the tripping zone such that the first and not the second tripping member will trip the first limit switch.
