RAILROAD'GRADE-CROSSING CONSTRUCTION. f

' l i Application filed March 2, 1925. Serial No. 12,608.

To all whom it may concern:

Be it known that I, CLEM DRENNoN, a citizen of the United States, residing at Edwardsville, in the county of Wyandotte Y utility of devices of this character. i

VVit-h these and other objects in view, th invention consists in certain'novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is a transverse section of the im# proved device together with the side elevation of one of the ties and a pair of the rails in transverse section.

Figure 2 is a plan view of the parts shown in Figure 1. Y

Figure 3 is a sectional detail on the line The improved device is constructed in three sections, an intermediate section supported on the ties and between the rails, and lateral sections supported on the ties eX- ternally of the rails.

The intermediate section includes spaced supporting members 10, preferably of portion of I beams bolted or otherwise attached to the ties between the rails, one of the ties being represented at 11 and the rails at 12. Bearing upon the supports 10 is a metal plate 13 with downturned side edges 14, the latter spaced from the confronting faces of the balls or treads of the rails 12.

The supports 10 are so proportioned that the upper surface of the plate 13 is located below the upper lines of the treads of the rails 12. The iange 14 is extended above the upper line of the plate 13, and even with the upper lines of the balls or treads of the rails 12.

The upper portions of the supports 10, v

at the ends are cut away at an angle, as shown in Figure 3, and the adjacent portions of the plate 13 bent down over the cut away portions as shown at 16 in Figure 3, to form inclined approaches to the bodypf the plate from either direction, Stop strips 17 are attached to the outer parts of the inclined portions 16 of the plate 13, as shown in Figure 3.

Disposed upon the plate 13 and its inclined margins 16 is a layer of asphalt or the like, and indicated at 18, the extensions 15 and the strips 17 operating as stops to confine the asphalt in position and prevent-Y ing it from spreading.

Attached -to the lower outer faces of the fianges 14 are strips 19 preferably of hard wood, and extending beneath the balls or treads of the rails 12, and operative to prevent foreign matter from passing between the rails and flanges.

The lateral portions of the improved device are alike so that the description of one will suffice for both, and consist ofy supporting members 20, preferably of I beams, and attached to the ties 11 externally of the rails 12. Bearing upon the beams 2O are plates 21 with downturned edges 22and 23.

The supports 2O are so proportioned that the upper surfaces of the plates 21 are located below the upper line of the balls or treads of the rails 12, and attached to the outer faces of the turned down portions 22 and 23 are stop strips 24 and 25, while like stop strips 26 are supported at the ends of the plates 21, the strips operating to confine lthe asphalt covering 27.

The bearing surfaces 18 and 27 are in alinement with the upper lines of the treads of the rails 12, as shown, and present an even uniform surface unbroken except for l ,A y l 1,550,519v

UNITED STATES the relatively narrow space between the flanges 14 and the balls or treads of the rails,

for the passage of the flanges of the car' tion of the ordinary asphalt pavement.'

With a device thus constructed, the crossing is no different from the roadway at each side of the crossing.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be un derstood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle o'f the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is l. A grade crossing comprising supports adapted to bear upon railway ties adjacent to the rails, plates bearing upon the supports and with downturned edges, stop ribs directed above said downturned edges and extending above the upper lines oit' the same, anda layer or' cementitious material dispose l on the plate and confined at the edges by said ribs.

2. A grade crossing comprising supports adapted to bear upon railway ties adjacent to the rails, plates bearing upon the supports and with downturned edges, stop ribs directed above said downturned edges and extending above the upper lines of the same,

a layer of cementitious material disposed on the plate and confined at the edges by said ribs, and a guard strip attached to one downturned edge of each strip and extending beneath the tread of the rail.

3. A grade crossing comprising supports adapted to bear upon railway ties adjacent to the rails, plates bearing upon the supports and with downturned edges, stop ribs directed above said downturned edges and extending above the upper lines of the same, a layer ot cementitious material disposed on the plate and' conlined at the edges by said ribs, a guard strip attached to one downturned edge ol' each rib and extending beneath the tread of the rail, and a strip of ,yieldable material attached to the guard
