Title: The Innovations of Vaughn Terrey Hawthorne
Introduction
Vaughn Terrey Hawthorne is a notable inventor based in Lisle, IL (US). He has made significant contributions to the field of railcar technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
Hawthorne's latest patents include a "Dynamically stable, lightweight railcar support system." This invention features a freight railcar undercarriage constant-contact sidebearing arrangement that provides a load force transfer mechanism with a more direct or less redundant force transfer path between the railcar body and the sideframe and wheels of a truck assembly. This system eliminates the need for a bolster center plate structure for load transfer, carries all load forces through the side bearing assemblies, and fulfills the dynamic operating requirements of the American Association of Railroads standards. It also reduces the weight of the railcar while maintaining load-carrying capacity and is particularly adaptable to three-piece truck assemblies commonly used on freight railcars.
Another significant patent is the "Railcar truck bearing adapter construction." This invention provides an integrally cast bearing adapter arrangement in the pedestal of a railcar truck side frame. The side frame is cast with a pedestal jaw that operates as a bearing adapter to receive and grasp a bearing assembly outer surface at a horizontal diameter for an axle end. This design avoids the manufacturing and assembly tolerances from discrete component assemblies, thereby minimizing angular displacement between each mated axle and side frame.
