ABSTRACT:
A presser foot for a sewing machine includes a shank detachably connected to a sewing machine presser foot bar. The shank has a transverse slot formed at the bottom thereof and a lug provided with a slit extending rearwardly from the back thereof. A lever is pivotally connected to the lug. A plate bridges both the lug and the lever to hold opposite ends of a torsion spring positioned in the slit of the lug to urge the lever by its biasing force. A rod is connected at its base to the lower end of the lever and movably extends through a longitudinal bore to project into the transverse slot of the shank until a stopper of the rod touches the edge of the bore. A presser foot shoe has a pair of supports for supporting a shaft extending transversely of the shoe and adapted to be received in the transverse slot and retained therein by the forward end of the rod closing the open side of the transverse slot. The shank is formed with a vertical groove at one side thereof for receiving the presser foot bar therein and has a colored plate arranged on the front thereof to prevent reflection of rays thereon.
