ABSTRACT:
A sewing machine work feeding mechanism of the drop feed variety having a feed dog adjustably supported at one end of an elongated feed bar. The pivot end of the feed bar is supported between a pair of pintles by a trunnion pin. The trunnion pin is journalled in a threaded pivot pin which is supported within the feed bar by a threaded sleeve which is free to rotate within the pivoted end of the feed bar. The inclination of the feed dog with respect to the throat plate may be adjusted by turning the threaded sleeve against the threaded pivot pin, thereby changing the height of the feed bar with respect to the plane of the support pintles. The feed dog is attached to the feed bar by a feed dog carrier and a threaded stud which permits the height of the feed dog carrier to be adjusted relative to the feed bar, thereby allowing independent adjustment of the height of the feed dog above the throat plate.
