ABSTRACT:
A sewing machine presser foot is provided with a detachable sole plate connected to the spaced apart arms of a support member by means of a compressible pin assembly secured to the arms and projecting from the sides thereof. The sole plate is provided with inclined flanges on its upper surface and aligned openings beneath the flanges. When the sole plate is moved upwardly toward the support member the projecting ends of the pin assembly are engaged by the ramps and compressed toward each other to permit the projecting ends to engage in the openings in the sole plate upon release of the compressive force on said ends.
