  • Patent number: 6409160
    Abstract: A spring assembly having a coil containing a core and methods and apparatus for manufacturing same are disclosed. The coil includes a core between reduced portions of the coil. One device for manufacturing the coil includes a coiling machine having an insert device operable with a coiler. The coiler is programmed to form coils of appropriate diameter along the length of the coil, including a diameter sufficiently large to contain the core and two diameters sufficiently small to retain the core in the coil. The insert device transfers the core to the coil after the first small diameter is formed and before the second small diameter is formed. The coil with the core contained between the two small diameters is thereby manufactured in a unified automated process.

  • Patent number: 6220586
    Abstract: A multiple torsion spring assembly according to the present invention may be provided with a coiled helical torsion spring. The spring has first and second end coils, and a plurality of intermediate coils between the first and second end coils. The first end coil inner diameter is less than the inner diameter of the intermediate coils. The second end coil inner diameter is less than the inner diameter of the first end coil. The spring may be used to control a throttle return of a throttle body. Methods of manufacturing spring assemblies are also disclosed.

  • Patent number: 6006449
    Abstract: A shoe having a preassembled spring assembly incorporated into the sole thereof is provided. The spring assembly includes a pair of plates having a plurality of apertures formed therein. The pair of plates define an upper plate and a lower plate in which the apertures formed in the upper and lower plates are axially aligned when the upper plate is disposed directly above the lower plate. A plurality of spring members are disposed between the upper and lower plates. The spring members are axially aligned with the plurality of apertures. A mechanism for retaining the spring members between the upper and lower plates is also provided. The mechanism for retaining is designed for retaining the upper and lower plates at a predetermined distance.

  • Patent number: 5368283
    Abstract: A torsion spring assembly particularly adapted for use in closing the throttle valve of an automotive throttle body. The assembly includes two bushings formed with sleeves adapted to telescope into the end portions of a torsion spring. As an incident thereto, the bushings automatically interlock with one another to hold the bushings and the spring in assembled relation.
