Patents by Inventor Walter J. Sanborn

Walter J. Sanborn 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).

  • Belt noise/vibration control mechanism
    Patent number: 6033330
    Abstract: A tuned damping element is attached to an idler operating on timing belts of belt drive systems, in order to reduce the noise generated by these systems while simultaneously providing tension to the belts and providing the support and resiliency required for noise abated idler operation.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: March 7, 2000
    Assignee: Xerox Corporation
    Inventors: Chee-Chiu Joseph Wong, Walter J. Sanborn
  • Low noise active tracking mechanism
    Patent number: 5413536
    Abstract: A low noise active tracking pulley idler reduces noise and actively tracks belts entrained around it by storing up undesirable impact energy and using it to guide the belts positioned around it. The idler includes an idler that is an integral member and has two cylindrical end portions with a flexible middle portion between them.

  • Edge guide systems for belt tracking
    Patent number: 5316524
    Abstract: An apparatus for controlling the lateral alignment of a belt arranged to move in a predetermined path includes a first roll arranged to support a portion of the belt passing thereover. The first roll has first and second ends. A first centering assembly for the belt is located adjacent the first roll. The first centering assembly includes a first rotating member located adjacent a first end of the first roll and a second rotating member located adjacent a second end of the first roll. The first and second rotating members urge the belt to an equilibrium position on the first roll. In one embodiment, the first and second rotating members are rollers which may either be tapered or crowned. In a second embodiment, the rotating members are driven rollers which rotate towards each other. In a third embodiment, the two rotating members are endless tracking belts which rotate towards each other.

  • Low noise timing belt
    Patent number: 5215504
    Abstract: Low noise timing belts for use in belt drive systems include either perforations cut into their thin segments or spiral grooves cut into their thick segments in order to allow air pockets to escape in all directions during teeth engagement of belts and pulleys, thereby reducing the noise generated in the process.
