Introduction
William D. Pilesi is a notable inventor based in Monroeville, PA (US). He has made significant contributions to the field of railroad technology, holding a total of 6 patents. His innovative designs focus on improving the efficiency and durability of concrete railroad ties.
Latest Patents
One of Pilesi's latest patents is the Concrete Railroad Tie Turnout Assembly. This invention features concrete railroad ties that incorporate steel plates cast directly into the concrete. The design allows for the top surface of each steel plate to be even with the top surface of the concrete tie. Fasteners for the rails can be welded to any location within the steel plate, providing flexibility in the positioning of rail fasteners. This innovation reduces the amount of concrete needed in a turnout by optimizing the length of the steel plate.
Another significant patent is the Concrete Railroad Tie Two-Piece Insulator Spacer and Fastening System. This system secures a rail to a concrete railroad tie using a two-piece insulator spacer. It enhances the resistance of the insulator spacer to crushing deterioration caused by laterally-directed compressive forces during service. The insulator spacer consists of an upper member and a post member, with the post member made from a composite material that provides electrical insulation.
