  • Patent number: 6364297
    Abstract: An improved torsion bar and socket system for a motor vehicle is provided. The socket includes a main hexagonal shaped opening having a plurality of scalloped openings extending therefrom. The socket includes a contact wall that defines a portion of the main hexagonal opening and an extending wall extending therefrom at an angle. The contact wall is adapted to contact the torsion bar and either apply rotational force thereto or receive rotational force therefrom. The extending wall is formed tangent to a circular wall which is also tangent to another contact wall. The circular wall and extending wall form a scalloped opening which is used during insertion of the torsion bar into the socket.

  • Patent number: 4714037
    Abstract: A needle looper assembly for a lockstitch sewing machine wherein the upper thread is retrieved by a sewing needle extending through a work material, which sewing needle has an extensible hook portion for catching an upper thread and drawing the same down through the work material to a looptaker in the bed of the sewing machine. The needle looper assembly is supported on the end of a lever pivotally carried in the sewing machine bed to extend transversely thereof. The lever has the needle looper assembly attached to one end thereof, and may be actuated by a cam so as to drive the needle looper assembly to an elevated thread catching position or to a retracted thread releasing position. Retaining means are provided associated with the needle looper to permit an upper thread to be caught and held during passage through a work material and to be released when in a retracted position adjacent the looptaker.

  • Patent number: 4694763
    Abstract: A bed slide for a sewing machine having a frame fabricated of a synthetic resin material, the bed slide extending beyond the throat plate on both sides thereof, and thereby beyond the cavity accommodating the looptaker, and two embodiments of devices attachable to the synthetic resin material spaced from the cavity for slidably retaining the bed slide therein. The first embodiment, a headed stud having a transverse slot therein for receiving a turned back edge of the bed slide is retained in an aperture molded in the synthetic resin material, with a resilient member exerting a pull on the stud for imparting a drag to the bed slide and retaining the same to the bed. In the second embodiment, a Z-shaped member has its lower bar fastened to the sewing machine bed and its upper bar inserted between the bed slide and a turned back end thereof. A portion of the upper bar is bent downwardly to provide for a drag resisting free motion of the bed slide.

  • Patent number: 4651662
    Abstract: A sewing machine frame and cover construction and fastening means for securing a warped cover in place over a frame opening without imparting frame distorting stresses. To obviate imparting stresses to the sewing machine frame as result of clamping a warped cover thereto, surfaces are provided at locations on the frame and cover chosen so that the surfaces engage simultaneously in spaced localized areas when the warped cover is positioned loosely over the frame opening. Fastening means located within the localized areas of engagement of these surfaces clamp the cover securely in place without disturbing the warp.
