RAILROAD-GROSSI NG.

SPECIFICATION forming' part of Letters Patent No. 758,964, dated May 3, 1904.

Application filed August 22, 1903.

To all whom t may concern:

' Be it known that I, HADLEY E. GREEN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Railroad-Crossing, of which the following is a specification. l

My invention is an improvement in railroadcrossings, and has for its object a continuous crossing, obviating the injurious jar caused by the wheel jumping the fiangeway formed atthe crossing-juncture of two rails. This object is accomplished by providing at thel crossing a flange-rail which gradually takes the weight on the Harige and returns it again to the tread of the wheel after the ilangeway has been passed.

My invention consists in providing at a crossing .a triple system of rails-that is, the usual tread-rail, a guiding flange-rail, and between these two a flange-rail concave in crosssection and adapted to gr ually receive the flange of the wheel to support said flange as the tread jumps the fiangeway of the crossingrail and to gradually relievbitself of the weight of the iiange and return the weight t0 the tread oi' the wheel after the crossing has been passed.

My invention consists also in the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claim, and shown in the-accompa nying drawings, in which- Figure l is a perspective view of my crossing. Fig. 2 is a perspective view of a Hangerail. Fig. 3 is a cross-sectional view of the rails in position. Fig. 4 is a cross-section showing an additional strengthening-rail added. y

In the drawings, A represents the main or tread rail. At the crossing there is arranged adjacent and on the inside of the tread-rail a flange guide-rail B, the base of which contacts with the base of the tread-rail. Thesevare the usual T-shaped rails. Fitting snugly between these two rails, bearing evenly on'their bases Serial No. 170,443. (No model.)

and against their adjacent side portions, is the base C of the iiange-rail. This base carries a Yof the other two. There will .thus be formed a continuous flange-rail overlapping the broken main rails. As the wheels approach the crossing the iianges will ride on the concaved portion of the rail, and thus support the wheel while the tread is passing the flangeway of the rail crossed. As soon as the crossing is passed the inclination of the portion C will gradually throw the weight on the tread of the wheel. Inlconstructing this crossing the rails A, B, and C are secured by the same bolts, as shown at D.

When desired, a fourth strengthening-rail E can be bolted adjacent the rails A, as shown in Fig. 4..

It will be obvious from the above description and from the drawings that there will be no jar as the train passes the crossing.

Having thus fully described my'invention, what I claim as new, and desire to secure by Letters Patent, is

A railroad-crossing comprising the main and guide rails, aange-rail having the continuous base C, arranged between and supported by the bases of the main and guide rails, the longitudinal central raised portion C', having the intermediate portion O2, adapted to support the flange of a wheel, and inclining downwardly to the base oneach side of the intermediate portion, the said central portion having a concaved upper face adapted to receive the wheel-ange.
