ABSTRACT OF THE DISCLOSURE An improved top feed arrangement for cooperation with a lower feed dog of a sewing machine, the lower feed dog cyclically engaging and disengaging the lower surface of material to be sewn in order to move that lower surface along a predetermined path through and past the sewing machine. The top feed arrangement comprises an upper feed dog carried by an arm that is linked to an oscillatory take-off from the primary drive means of the sewing machine. The arm is connected to those drive means at one end in a pivotal connection and the upper feed dog is carried at the other end of the arm. Biasing means bear against the arm at a location adjacent the upper feed dog. A lifter means, also responsive to the primary drive system of the sewing machine, periodically moves the upper feed dog in a direction away from the lower feed dog against the force of the biasing means. The linkage from the sewing machine drive to the top feed is housed in a recessed area removed from the work and an uncluttered large work area is provided.
