  • Patent number: 4195830
    Abstract: A material guiding device for feeding material to a stitch-forming area of a sewing machine which has a rail guide over which the material is placed for guiding movement from a charging point to the stitch-forming area, comprises a braking weight which has a bottom recess of a size to receive the rail guide with the material thereon so as to permit engagement of the weight over the material so as to move with the material during the feeding operation and to provide a braking action thereon. The construction includes a deflector adjacent the stitch-forming area which deflects the weight into a braking weight return track in the form of a slide or chute which has an opening adjacent the stitch-forming area and is inclined downwardly to a delivery end which is remote from the stitch area at the charging point for the material so that a weight may be returned automatically to a place at which it may be applied to a material at the charging point.
    Type: Grant
