Stephen W. Simons has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10778051
    Abstract: A rotor fabrication method is provided. The rotor uses pre-fabricated conductive rotor bars in which the ends have been shaped and sized to fit within corresponding end cap receptacles. After assembly, the structure is compressed, thereby achieving mechanical and electrical coupling between the conductive rotor bars and the end caps. Locking members disposed at either end of the assembly maintain the desired level of axial compressive force on the structure.
    Type: Grant

  • Publication number: 20170229932
    Abstract: A rotor fabrication method is provided, along with the resultant rotor assembly. The rotor uses pre-fabricated conductive rotor bars in which the ends have been shaped and sized to fit within corresponding end cap receptacles. After assembly, the structure is compressed, thereby achieving mechanical and electrical coupling between the conductive rotor bars and the end caps. Locking members disposed at either end of the assembly maintain the desired level of axial compressive force on the structure.

  • Patent number: 4807860
    Abstract: A motorcycle front fork assembly is disclosed in which a hollow damper rod is connected at its lower end to lower end of a hollow fork leg which telescopically receives an upper hollow fork tube and with a piston at the upper end of the damper rod engaging the interior surface of the fork tube. A float is positioned within the fork tube to float on the fluid within the fork tube. A float tube in which the float is positioned can be provided above the damper piston rod and including a fluid regulation valve. At least one compression port can be provided for fluid communication between a compression chamber defined between the fork leg and the damper rod below the lower end of the fork tube and a valve provides one way communication from the interior of the damper rod to the compression chamber during extension of the stroke of the fork assembly. The valve can include a slide that can close off or open a replenishment hole and a fluid passageway in the slide which is spring biased closed but can be opened.
