Abstract
An upper feed mechanism positively driven in four directions above the work supporting surface of the machine for concommitantly advancing work along a predetermined feed path. The upper feed mechanism includes an upper feed dog carried on the presser arm of the machine. In the usual manner, the presser arm has a presser foot hinged at one end thereof. The opposite end of the presser arm is slidably pivoted relative the machine frame such that the presser arm, presser foot and upper feed dog mechanism may be conjointly moved sidewise as a modular assemblage thus permitting operating access to the sewing area of the machine.
