Abstract

Abstract A deck component for use in a highway railroad crossing. The component comprises a flat pad of molded, comminuted rubber dimensioned to lie with companion pads inside and outside the rails and spiked to the ties. Pad bearing is provided against the webs of the rails, as well as against the tie plates and the ties. The result is a stabilized crossing easily installed and of long life.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 245 words
For use in a highway railroad crossing including a pair of spaced rails, a plurality of rail-supporting ties, and a plurality of tie plates spiked to the ties and securing the rails thereto, each rail comprising a horizontal base, an intermediate vertical web, and a rail head; a deck component comprising: (a) a flat pad of molded, comminuted rubber, the pad being dimensioned to lie adjacent a rail with its undersurface supported on and bearing against the ties and its upper surface lying at an elevation, substantially parallel to tread surface of the rail head, to provide a smooth, traffic-crossing surface, (b) one lateral edge surface being contoured and dimensioned to form a foot and bear against substantially the entire web of each rail, (c) the undersurface perpendicular to said lateral edge surface and immediately adjacent thereto, said foot being contoured and dimensioned to provide an elongated surface adapted to bear against each adjacent rail base, (d) the undersurface parallel to and immediately adjacent each foot being recessed to provide a channel dimensioned and contoured to form a channel ceiling adapted to bear against the tie plate-spike assembly associated with the rail, thereby stabilizing the deck, (e) the upper surface perpendicular to and immediately adjacent said lateral edge surface being recessed to provide a channel dimensioned and contoured to receive the rail head, and when positioned between the rails to receive also wheel flanges, and (f) securing means for attaching the pad to the ties.
Claim 2
Dependent Claim 245 words
For use in a highway railroad crossing including a pair of spaced rails, a plurality of rail-supporting ties, and a plurality of tie plates spiked to the ties and securing the rails thereto, each rail comprising a horizontal base, an intermediate vertical web, and a rail head; a deck component comprising: (a) a flat pad of molded, comminuted rubber, the pad being dimensioned to lie adjacent a rail with its undersurface supported on and bearing against the ties and its upper surface lying at an elevation, substantially parallel to tread surface of the rail head, to provide a smooth, traffic-crossing surface, (b) one lateral edge surface being contoured and dimensioned to form a foot and bear against substantially the entire web of each rail, (c) the undersurface perpendicular to said lateral edge surface and immediately adjacent thereto, said foot being contoured and dimensioned to provide an elongated surface adapted to bear against each adjacent rail base, (d) the undersurface parallel to and immediately adjacent each foot being recessed to provide a channel dimensioned and contoured to form a channel ceiling adapted to bear against the tie plate-spike assembly associated with the rail, thereby stabilizing the deck, (e) the upper surface perpendicular to and immediately adjacent said lateral edge surface being recessed to provide a channel dimensioned and contoured to receive the rail head, and when positioned between the rails to receive also wheel flanges, and (f) securing means for attaching the pad to the ties.
Claim 3
Dependent Claim 42 words
The deck component of claim 1 wherein the ceiling of the channel in the undersurface is shaped in a stepped contour to provide adjacent ceiling segments of different elevation, one adapted to be adjacent the spikes and one adjacent the tie plates.
Claim 4
Dependent Claim 42 words
The deck component of claim 1 wherein the deck component is adapted for use as an outside-the-rail deck component and the channel in the upper surface is dimensioned and contoured to provide a vertical surface adapted to bear against the rail head.
Claim 5
Dependent Claim 27 words
The deck component of claim 1 wherein the securing means for attaching the pad to the ties comprises spikes penetrating the pad and driven into the ties.
Claim 6
Dependent Claim 25 words
The deck component of claim 1 wherein the pad has two contoured edge surfaces and is dimensioned to extend between the rails in a press-fit.
Claim 7
Dependent Claim 41 words
The deck component of claim 1 wherein each pad has a single contoured surface and is dimensioned to cooperate with a companion pad arranged side by side to form a composite pad dimensioned to extend between the rails in a press-fit.
