  • Patent number: 4329934
    Abstract: A needle holding device for a sewing machine having a needle with a cylindrical shank having a flat edge surface extending along the shank includes a needle bar for supporting the needle, a needle holder mounted to the needle bar and a holding screw to fasten the needle to the needle bar. The needle bar is formed with a vertical groove defined by a horizontal wall and an inclined wall which are adjacent to each other to define a wedge-shaped space. The needle holder has a vertical circular hole having an inner periphery and a transverse hole extended into the vertical hole. When the needle holder is mounted to the needle bar the inner periphery of the vertical hole and the wedge-shaped space of the needle bar groove form a wedge-shaped chamber into which the shank of the needle is inserted. The holding screw fastens the needle upon insertion into the needle bar when the flat edge of the shank is positioned against the horizontal wall of the groove.
