An improved upper roller feeding mechanism for a sewing machine which mechanism is contained entirely within the head of the frame of the sewing machine and wherein the roller is driven by a drive mechanism supported by the frame which includes a rotary shaft and means for converting the rotating movement of the shaft into an oscillating movement. A one way clutch is utilized to translate the oscillating motion into incremental rotary movement which is in turn transmitted to the roller.
