Richard S. Parr 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).
Abstract: A vehicle tire may have a tread with a circumferential groove defined by side faces of two circumferential ribs. The side faces may have a number of radially extending paddles formed by a pair of walls. A ratio of the length of one wall to the other may be at least 1.2.
Abstract: A tire includes a tread and a narrow, wavy, circumferential groove disposed on the tread, which extend around the tread in a circumferential direction. The narrow, wavy, circumferential groove has a first axial position associated with a minimum axial displacement, a second axial position associated with a maximum axial displacement, and the narrow, wavy, circumferential groove follows a serpentine path between the first and second axial positions. The narrow, wavy, circumferential groove has a first depth and a second depth, the first depth being a minimum narrow, wavy, circumferential groove depth and the second depth being a maximum narrow, wavy, circumferential groove depth. The narrow, wavy, circumferential groove follows a serpentine path between the first and second depths. The first depth of the narrow, wavy, circumferential groove and the second depth of the narrow, wavy, circumferential groove is between 0.10 mm and full tread depth.
Abstract: Various methods and apparatuses for creating a visual effect on a rubber article are disclosed. In one embodiment, a rubber article having a visual effect is provided, the rubber article comprising: a surface having at least one surface feature; and wherein the at least one surface feature comprises a plurality of linear elements creating a camouflage-shaped appearance.
Abstract: A tire includes annular beads, a body ply extending between the annular beads, and a circumferential belt disposed radially outward of the body ply. The tire further includes a circumferential tread disposed radially outward of the circumferential belt. At least three circumferential grooves divide the tread into two outer circumferential ribs and two inner circumferential ribs. A plurality of rib sipes are disposed on at least one circumferential rib. The tire includes a plurality of curvilinear spline sipes, wherein each curvilinear spline sipe has multiple inflection points. At least one curvilinear spline sipe is disposed on an outer circumferential rib and at least one curvilinear spline sipe is disposed on a different circumferential rib. A localized depth of the at least one curvilinear spline sipe disposed on the outer circumferential rib varies in proportion to the distance from the rib sipes that intersect the at least one curvilinear spline sipe.
