Patent ID: 7926634

Claim:
A third rail power insulating system, comprising: A) an insulator assembly comprising supporting insulators, each of said supporting insulators comprise a sidewall, a base, base holes, first channels, channel holes, a first top wall, distal ends, and a second channel, said insulator assembly mounted onto a single molded pedestal that is part of a track guideway, said insulator assembly supports a contact rail assembly, which supplies power to a transit vehicle, said insulator assembly further comprises an insulator anchor bolt assembly, a base shim plate, a bolt assembly, a lubricating shim, and supporting insulator retaining clips, said insulator anchor bolt assembly supports and restrains said contact rail assembly and insulates it from ground and structure, said lubricating shim comprises a second top wall and lateral tabs, said lateral tabs fit within their respective said first channels when said second top wall is positioned upon said second channel; and B) a cover board assembly comprising a support bracket assembly, cover board assembly retaining clips, a side cover board, and a top cover board, said side cover board and said top cover board mounted onto said support bracket assembly, said cover board assembly is also mounted onto said contact rail assembly, said top cover board comprises an elongated plate having sufficient curvature to contour said support bracket assembly, said top cover board also comprises an elongated lip at a first predetermined distance outwardly from said side cover board defining a first water runoff and preventing a first water stream from making contact onto the contact rail assembly, said support bracket assembly has a general C-shape and comprises a lateral wall, a third top wall, a base wall, a protrusion, and at least one cutout defining a channel to allow a second water runoff and prevent a second water stream from making contact onto said contact rail assembly.
