Thread cutter for sewing machine

Image Number 7 for United States Patent #5609117.

Obtained is a thread cutter for a sewing machine which can further readily and reliably cut a needle thread, a looper thread or a chain loop by pushing down a knob without driving the sewing machine. In this thread cutter for a sewing machine, a long groove is formed in a needle plate which is positioned behind a presser foot, and a fixed blade is so provided that its cutting edge is along an edge of the long groove. A movable blade which is pressed against the fixed blade by a plate spring is mounted on a spindle, and the spindle is rotated to vertically move the movable blade when the knob frontwardly projecting from the sewing machine is operated. The thread or the chain loop is cut by the vertical movement of the movable blade in association with the fixed blade.
