RALWAY-CROSSING' SURFACE.

Application ined August 1s, 192e. serial No. 129,516.

The objectof the present invention resides in the provision of a railway crossing surface, whereby the crossing can be more readily and conveniently traversed by pedestrians, and vehicles, the surface being constructed in a novel manner whereby one or more sections thereof can be readily and conveniently replaced from time to time as the occasion may require.

rlhe nature and advantages of the invention will be better understoodwhen the fcllowing detail description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed. 4

1n the drawing forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a plan view of the invention.

Figure 2 is a sectional view on line 2 2 of Figure 1 looking in the direction of the arrows.

Figure 3 Ais a sectional view on line 3 3 of Figure 2 looking in the direction of the arrows.

Figure 4 is a sectional view on line 4 4 of Figure 1.

1n Figure 1 'we have illustrated a railway crossing wherein the rails are indicated at 1G and supported on ties 11.

rl`he present invention contemplates the use of a plurality of runners or beams 12 which may be constructed from any suitable material, preferably wood, and adapted to be supported upon the adjacent ties 11 and secured thereto in any suitable manner, the beams being arranged in spaced parallel relation between and at opposite sides of the rails as illustrated in Figure 1. The surface over which pedestrians and vehicles pass is preferably constructed of reinforced concrete, and made up in sections of a size to lie between the rails 10 and at opposite sides of the rails as shown.A 1n other words the surface is made up of a plurality of end sec tions 13 which are arranged at the opposite outer sides of the rails 10, and intermediate sections 14 of a size to lie between the rails, although these sections are spaced an appreciable distance from the rails proper as illustrated in Figure 3. The sections are of a depth to lie flush with the ground or surface 15 and are provided with openings to accommodate suitable means for holding said sections against displacement, and at the same time to allow any one or more of the sections of the entire surfaceto be replaced from time to time as the occasion may require. In other words each section of the surface is provided with a plurality of openings, each of which receives a metallic sleeve 1G, while projecting above each beam or runner 12 are a plurality of pins 17 arranged lto be received by the sleeves 16 embedded in the adjacent sections of the. surface. The sections of course can vary insize according to the type cf crossing to be made and also in accordance with the place where the surface .is to be used. The surface may be vperfectly fiat as shown or may be corrugated or otherwise roughened as desired without departing from the spirit of the invention. Furthermore the pins 17 are slightly smaller than the diameter of the sleeves 16 so that the sections of the surface can be freely placed upon the pins and removed therefrom as the occasion may require. If desired, the runners or beams 12 may be secured to the ties in the manner illustrated in Figure 4, namely byuse of screws 18. When these elements are used, the openings in the surface sections are suitably spaced apart to lie directly above the adjacent ties 11, inasmuch as the screws 18 are adapted to be passed through the openings in said sections as clearly disclosed in Figure 4. It will be noted that the openings in the sections are counter-sunk to allow the heads of the screws 18 to lie beneath the surface of the said sections, and when the screws are arranged in the manner shown in Figure 4, the ties 11, runners 12 and surface sections are all secured together as a unit, consequently the surface sections are held immovably in proper relation t0 each other. 1t might be stated that if desired the surface sections may be edged with angle iron.

lVhilc it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, we desire to have it understood, that we do not limit ourselves to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is:

1. A railway crossing surface comprising reinforced concrete sections adapted to be arranged between and at opposite sides of the rails flush with the surface 0f the ground, spaced parallel beams arranged at opposite sides of the rails and upon which said sections repose, and fastening devices rising from the beams andV engaging the sections for holding said sections against casual displacement and permitting said sections to be independently placed in position for use or removed from said beams.

2. A railway crossing surface comprising spaced parallel beams arranged at opposite sides of the rails and supported on the ties therefor, surface sections arranged between and at opposite sides of the rails and supported byV said beams flush With the surface of the ground, said sections having openings therein, and pins rising from said beams and adapted to be received by said openings to hold said sect-ions against casual displacement and permit said sections to be independently removed.

3. A railway crosing surface comprising spaced parallel beams arranged between and at opposite sides of the rails and supported by the ties therefor, reinforced concrete surface sections supported by said beams between and at opposite sides of the rails flush 4f... A railway crossing surface comprising a plurality of reinforced concrete sections adapted to be arranged between and at opposite sides of the rails, spaced parallel beams arranged at the opposite sides of the rails and upon Which said sections repose, said sections having openings formed therein, and fastening` elements passed through said openings and through the adjacent beam and secured t0 the tie of the rail, whereby all of said parts are held fixed relatively, said fastening elements including heads counter-sunk in the said sections.

in testimony whereof WeV affix our signatures.
