US Patent:

20130233935, Sep 12, 2013

Filed:

Mar 4, 2013

Appl. No.:

13/783735

Inventors:

Tom HABEL - , US
David J. LAWRENCE - Greer SC, US
Ernest J. ALLISON - Hartwell GA, US

International Classification:

E01B 9/68

US Classification:

238264

Abstract:

A gauge-plate insulator for positioning between and mounting to two rail-spacing members that in turn extend transversely between and mount to two parallel rails to mechanically interconnect but electrical insulate the rail-spacing members and thus the parallel rails. The insulator includes a plate, front and rear mounting holes extending vertically through the plate, and a tongue extending downward from the plate along its lateral midsection from front to back. In typical embodiments, the insulator includes elongated platforms surrounding the mounting holes and arranged perpendicular to the tongue, and the insulator is of a one-piece monolithic construction made of a material selected for mechanical strength and electric insulation. And in some embodiments the insulator includes a tented top surface, ribs extending perpendicular to the tongue, and/or multi-level platforms.
