Winship Stinson Reed, III 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).

  • Bristle sub-assemblies having parallel pairs of bristles; and methods of making same
    Patent number: 6478925
    Abstract: An apparatus for forming bristle sub-assemblies includes a vertically oriented slot, which is formed by two endless belts. A wheel disposed above the slot pushes a bristle string into the slot. The bristle string has a plurality of bristles connected to a base string in two rows. The bristle rows can be horizontally oriented, so that all of the bristles are co-planar in a horizontal plane, or they can be angularly oriented with the base string at the vertex of the angle. When the bristles are pushed into the slot, they bend to adopt a new, substantially parallel orientation. An ultrasonic heater heats the bent bristles to re-set the thermoplastic material from which the bristles are made so that after cooling, the parallel orientation is maintained.
    Type: Grant

    Date of Patent: November 12, 2002
    Assignee: E.I. du Pont de Nemours & Company
