Eric R. MacPherson 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: 9586443
    Abstract: A segmented tire apparatus includes generally arcuate tire segments each including a radial tread extending along an outer circumference of the respective tire segment. Each tire segment further includes a first group of semi-transverse treads extending from at least adjacent to the radial tread in a first direction and a second group of semi-transverse treads extending from at least adjacent to the radial tread in a second direction. Each one of the second group of semi-transverse treads is positioned in an offset but substantially aligned orientation relative to an associated one of the first group of semi-transverse treads. In an alternative embodiment, a segmented tire apparatus includes a plurality of tire segments mountable onto a rim, with a plate positioned between a first one of the plurality of tire segments and a second one of the plurality of tire segments.

  • Patent number: 8678054
    Abstract: A Segmented Tire Apparatus for improving the reliability and performance of irrigation systems. The Segmented Tire Apparatus includes a plurality of arcuate tire segments coupleable end to end to form a circular tire. Each of the arcuate tire segments has a plurality of treads which may be radial, transverse, or semi-transverse. Additionally the apparatus may be filled with a closed cell foam to provide stability and rigidity while inhibiting water from collecting on the inside of the tire.
