ABSTRACT:
A drag link feeding mechanism for a sewing machine having its feed stroke adjusting element in the form of a ring nested within and mounted on a supporting ring which in turn is easily and simply attached to the web of the sewing machine frame. This allows the mechanism to be simple and mechanically compact so that movements of force are minimized and work loads imposed on the mechanism by heavy fabric are taken up by large bearing surfaces.
