16 Claims.

The object of the present invention is to provide a railroad crossing structure that has peculiarly eflicient Wear and weather-resisting qualities, and involves units or parts which can i be readily manufactured and easily assembled.

An embodiment of the invention that is at present considered the preferable one, is illustrated in the accompanying drawings, wherein:--

Figure 4 is a detail sectional view on the line 44 of Figure 1.

Figure 5 is a bottomplan view of one of the tread bars.

Figure 6 is a top plan view of a portion of the same.

Figure 14. is a side elevation of the same.

Figure 15 is a cross sectional view on an enlarged scale and on the line l5-l5 of Figure 14.

In the embodiment disclosed, a section of a standard railway is illustrated, comprising the ties or sleepers 16 supporting the rails 1'7. At the crossing the ties have mounted thereon carrier bars. These bars are of channeled formation, and as shown, are of two types. The bars of one set are designated generally by the reference numeral l8, and one is shown in detail in Figures 13, 14 and 15. As therein shown, the bar is of channeled formation, comprising a bottom wall 19 and upstanding side walls 20, the latter having inturned bearing flanges 21. Holes 22 through the central portion of the bottom wall 19, are adapted to receive spikes 23 or other suitable fasteners by which the bars 18 are secured to the ties, these spikes being readily driven and accessible through the space between the inner edges of the flanges 21.

The said bars 18 are placed on every second tie at the crossing, and on the intermediate ties are located other carrier bars 24. One of tehse bars is shown in detail in Figures 10, l1 and 12. It is of metal channeled formation, compris- Q0 ing a top wall 25 and depending side walls 26, the latter having along their lower edges inturned flanges 2'7 constitutin the supporting feet. The top wall 25 has upset from the material thereof sets of outstanding ears or lips 28, the intermediate portions of which are preferably depressed, as shown at 29. These carrier bars 24 are secured in place by spikes or other fasteners 30 driven through openings 31 in the top walls and entering the ties on which said carrier'bars 7 are placed.

Supported on the two sets of

carrierbars

18 and 24 transversely thereof and therefore longitudinally of the rails and between said rails, are what may be termed tread or roadway bars. These are designated generally 31. The detail structure of one of these bars is shown in Figures 5, 6 and 7. Each is of channel formation and consists of a top or bearing wall 32, which may be suitably roughened on its upper face, as illus- 8 trated in part at 33 in Figure 6, and also in Figure '7. Depending from the side edges of this top wall 32 are side supporting walls 34 terminating at their lower ends in inturned supporting flanges 35 that constitute feet which rest upon the

bars

18 and 24. It will be noted by reference to Figures 5 and 7 that the flanges 35 are cut away at intervals and as shown at 36, the length of the spaces thereby formed being slightly greater than the length of the lips 28 of the supporting bars 24. These lips 28 are elevated sufficiently above the top wall 25 of the bars 24 to permit the sections of the flanges 35 to pass beneath said lips, as shown in Figure 3.

It will be evident then that if the

carrier bars

18 and 24 are secured on the ties 16, the tread bars 31 can be placed side by side thereon, the lips 28 entering through the spaces 36. The tread bars then have only to be moved a short distance longitudinally to cause them to be interlocked 10 or held by said lips 28. A roadway across the space between the rails is thus produced and held assembled.

In order to prevent any low hanging elements of the cars engaging the ends of the tread bars and perhaps tearing them loose or otherwise injuring the crossing and to prevent any longitudinal displacement of said tread bars, guard plates 37 are located at the ends of the crossing. These plates are of suitable fiat metal with their main no portions upwardly inclined and having outer horizontal flanges 38 that rest upon the adjacent tie to which they are fastened by suitable bolts or spikes 39. The upper end portion of each plate has a downturned flange 40 (see Figure 9), and this flange is provided with outturned lugs 41 that enter the open ends of the tread bars.

It will be evident that this is a structure that can be made of units of formed metal and that these units may be readily placed in position and assembled into a crossing or like structure. When assembled the parts are all effectively interlocked so that they will retain their position. Being of metal they will withstand weatherconditions and trafiic more successfully than ordinary wood plank or the like usually employed for crossings.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
