Signal bond plate

摘要

A signal bond plate system for electrically bonding onto a railroad rail comprising: first and second conductive plates, first and second wires; and first and second conductive washers; a boltlike attachment means attaching, in order, the first conductive plate, the first conductive washer, a web of the rail, the second conductive washer, and the second conductive plate; the conductive plates each having an inside surface proximal to the web of the rail and an outside surface distal to the web of the rail; each wire having a wire first end and a wire second end; each conductive plate having a conductive plate first end and a conductive plate second end; the first wire first end is attached to the first conductive plate near the first conductive plate first end at a first attachment point; the first wire second end attached to the rail; the second wire first end attached to the second conductive plate first end at a second attachment point; the second end of the second wire attached to the rail; the first cover plate attached to the outside surface of the first conductive plate; and the second cover plate attached to an outside surface of the second conductive plate.

主权项

1. An apparatus for making electrical connection to a railroad rail comprising:
a first conductive plate and a first conductive washer; an attachment device attaching, in order, the first conductive plate, the first conductive washer and a first side of a web of the rail; wherein the first conductive washer is in electrical contact with the first side of the web of the rail, the first conductive plate is in electrical contact with the first conductive washer and the first conductive plate is in electrical contact with the rail via the first conductive washer; and wherein the first conductive washer has a conductive washer inner surface substantially complementary to a side of the rail as defined by a head of the rail, the first side of the web of the rail, and a foot of the rail; and wherein the first conductive washer has a conductive washer outer surface substantially complementary to an inside surface of the first conductive plate.
