Abstract: A sewing machine presser foot includes a pin member pivotally supported in a pair of spaced lugs mounted on a sole member. The pin member has a strip between its journal ends, the strip extending through a groove provided through a stem member to be installed on a sewing machine bar. The groove has a cross-section of an ellipse having a pair of opposed walls across which the minor axis extends. The pin member is normally movable axiswise for its positional adjustment relative to the stem member. Upon pivotal movement of the pin member about its axis, edges of the strip come into frictional engagement with the walls of the groove, to thereby arrest axial movement of the pin member relative to the stem member. A slot is provided in the stem member, the slot being coextensive in length and communicating with the groove for the passage therethrough of the strip. One of the journal ends of the pin member has a knob or lever for rotation thereof.

Abstract: A sliding clasp fastener is disclosed which is provided with a stop means at an end thereof for limiting the reciprocal movement of a sliding member. This stop means particularly adaptable at a top end of the fastener is comprised of an arcuately shaped prong extending on the base side of fastener elements and substantially flush with the plane of these fastener elements for engagement with a flanged portion of the slider.
