Railroad crossing structure

Claim 2

A railroad crossing structure for use with a highway railroad crossing having a pair of spaced, substantially parallel rails, a plurality of elongated ties subtending and supporting said rails and being disposed transversely thereof, and means for securing said rails to said ties, said railroad crossing structure comprising: (a) an elongated elastomeric pad of a width proportioned to span the distance between said pair of spaced, substantially parallel rails, and having along at least one edge thereof a channel for receiving therein the flange portion of a wheel of a railroad car and for providing a drainage channel for water and the like; (b) a flexible plate of a generally concave cross-section imbedded within said elastomeric pad, said flexible plate having a deflecting action as vehicles drive over said railroad crossing structure which functions as a shock absorber to provide a vehicle smoother transition over said railroad crossing structure and to force the edge of said flexible plate towards said channel to break up foreign objects such as snow, ice and the like which may form or collect in said channel; and (c) tie down means for securing said elastomeric pad atop said plurality of ties, said tie down means comprising anchor means, the opposite ends of said flexible plate being coupled and secured to the respective ones of said anchor means.

Claim 3

The railroad crossing structure of claim 1, further comprising securement means affixed to the opposite sides of said flexible plate along the longitudinal edges thereof, said tie down means further comprising a pair of rod means extending longitudinally through said elastomeric pad and secured respectively to the opposite side edges of said flexible plate by means of said securement means, the opposite ends of said rod means being secured to the respective ones of said anchor means.

Claim 4

The railroad crossing structure of claim 1, further comprising a cylindrical channel on each of the opposite side edges of said flexible plate along at least a portion of the longitudinal length thereof, said tie down means further comprising a pair of rod means extending longitudinally through said cylindrical channels and having the opposite ends thereof secured to the respective ones of said anchor means.

Claim 5

The railroad crossing structure of claim 3, wherein said anchor means comprise a metal plate fixedly secured to each of the two ties disposed adjacent the opposite longitudinal ends of said elstomeric pad, the ends of said pair of rod means being extended through apertures formed in said metal plates and secured therein.

Claim 6

A railroad crossing structure for use with a highway railroad crossing having a pair of spaced, substantially parallel rails, a plurality of elongated ties subtending and supporting said rails and being disposed transversely thereof, and means for securing said rails to said ties, said railroad crossing structure comprising: (a) a pair of elongated elastomeric pads of a width proportioned to span the distance between said pair of spaced, substantially parallel rails, each of said pads having along at least one edge thereof a channel for receiving therein the flange portion of a wheel of a railroad car and for providing a drainage channel for water and the like; (b) a flexible plate of a generally concave cross-section imbedded within each of said elastomeric pads and having a cylindrical channel on each of the opposite sides thereof along at least a portion of the longitudinal length thereof, said flexible plates having a deflecting action as vehicles drive over said railroad crossing structure which functions as a shock absorber to provide a vehicle smoother transition over said railroad crossing structure and to force the edge of said flexible plate towards said channel to break up foreign objects such as snow, ice and the like which may form or collect in said channel; and (c) tie down means for securing said elastomeric pads atop said plurality of ties, said tie down means comprising anchor means, and rod means extending longitudinally through each of said cylindrical channels, the opposite ends of said rod means being secured to the respective ones of said anchor means.

Claim 7

A railroad crossing structure for use with a highway railroad crossing having a pair of spaced, substantially parallel rails, a plurality of elongated ties subtending and supporting said rails and being disposed transversely thereof, and means for securing said rails to said ties, said railroad crossing structure comprising: (a) a pair of elongated elastomeric pads of a width proportioned to span the distance between said pair of spaced, substantially parallel rails, each of said pads having along at least one edge thereof a channel for receiving therein the flange portion of a wheel of a railroad car and for providing a drainage channel for water and the like; (b) a flexible plate of a generally concave cross-section imbedded within each of said elastomeric pads and having a cylindrical channel on each of the opposite sides thereof along at least a portion of the longitudinal length thereof, said flexible plates having a deflecting action as vehicles drive over said railroad crossing structure which functions as a shock absorber to provide a vehicle smoother transition over said railroad crossing structure and to force the edge of said flexible plate towards said channel to break up foreign objects such as snow, ice and the like which may form or collect in said channel; and (c) tie down means for securing said elastomeric pads atop said plurality of ties, said tie down means comprising anchor means, and rod means extending longitudinally through each of said cylindrical channels, the opposite ends of said rod means being secured to the respective ones of said anchor means.

Claim 8

The railroad crossing structure of claim 5, wherein said anchor means comprise a metal plate fixedly secured to each of the two ties which are disposed adjacent the opposite longitudinal ends of said pads, the ends of said rod means being extended through apertures formed in said metal plates and secured therein.

Claim 9

The railroad crossing structure of claim 6, wherein the abutting edges of said pair of elastomeric pads are provided with complimentary interlocking means for releasably securing the abutting edges thereof together and for sealing the abutting edges so as to prevent water and the like from passing between and through the abutting edges.

Claim 10

The railroad crossing structure of claim 7, wherein the opposite edges of said pair of elastomeric pads which are adjacent the respective ones of said rails tightly abut against said rails and are formed with a generally V-shaped channel for receiving therein the flange portion of a wheel of a railroad car and for providing a drainage channel for water and the like.

Claim 11

The railroad crossing structure of claim 5, further comprising a plurality of said elastomeric pads disposed between said rails in end to end relationship, said rod means extending longitudinally through said pads in end to end relationship to secure said pads in place.

Claim 12

The railroad crossing structure of claim 9, wherein the abutting edges of said elastomeric pads all are correspondingly formed with complimentary interlocking means, whereby the edges of said pads abutted and secured together are sealed so as to be substantially moisture-proof.

Claim 13

The railroad crossing structure of claim 5, further comprising an elastomeric side edge pad disposed between the respective ones of said rails and the adjacent edges of the highway, said side edge pads being proportioned to fit tightly between said rails and the adjacent edge of the highway, said elastomeric side edge pads each having a flexible plate of a generally concave cross-section imbedded within it, said flexible plates having a cylindrical channel on each of the opposite sides thereof along at least a portion of the longitudinal length thereon, and tie down means for securing said elastomeric side edge pad atop said plurality of ties comprising plate means fixedly secured to the two ties which are disposed adjacent the opposite longitudinal ends of said elastomeric side edge pads, and rod means extending longitudinally through each of said cylindrical channels, the opposite ends of said rod means being secured to the respective ones of said plate means.

Claim 14

The railroad crossing structure of claim 11, wherein said plate means comprising said anchor means extend to overlap the corner edges of the highway along the sides thereof and are secured to the side of the highway, whereby cornering of the crossing and the highway is prevented.
