Abstract
A railroad crossing structure comprising one or more elastomeric pads which preferably have a flexible plate of a concave cross-section imbedded within them. The elastomeric pads are abutted together side-by-side and/or end-to-end to form the crossing, and the abutting edges thereof are formed with interlocking means to provide moisture-proof seams between them. The elastomeric pads are secured in place by means of rods extended longitudinally through them, with the ends of the rods being secured to anchor means.
Claims12
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.
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.
