RAILWAY CROSSING.

Application filed December 14, 1925. Serial No. 75,375.

[ all whom it may concern.-

Be it known that I, ASA GIL ERT FARMER, a citizen of the-United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented a' new and useful Railway Crossing, of which the following is a specification.

This invention relates to railway crossings and is designed primarily for use in lieu of the planks ordinarily provided between the rails: of the track and adjacent the outer sides thereof so that vehicles and pedestrians can travel across the track on a level with the tops of the rails.

Boards and *similar means heretofore used have been objectionable because they readily work loose, will splinter and injure the tires of vehicle crossing the track and because they soon become worn. I Iowever such devices have been used because they can be easily removed when desired to repair the track at the crossing.

It is an object of the present invention to provide a crossing made up of castings so shaped as to fitproperly against and between the rails, means being provided whereby these castings are strengthened so as to resist the heavy loads to which they are subjected.

A further object is to provide the cross ing sections with means for engaging the ties thereunder for the purpose of holding the sections against transverse creeping while in use and possible displacement of the rails.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise en'lbodin'lent of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure l is a top plan view of the crossing members positioned relative to the rails of the track, only a few of the surface studs on the members being shown.

Figure 2 is an end elevation of the crossing, the rails being shown in section.

Figure 3 is a vertical transverse section though the crossing members and the rails.

rails and side members i to be placed again Figure 4 is a bottom plan view of a portion of oneof the members of the crossing,

Figure 5 is an enlargedvertical section t-hrougha port on of one of the members.

Referring to the figures by characters of reference 1 designates track rails secured in the usual manner-upon ties 2. The crossing constituting the present lnvention in cludes ame1nber-3 to be placed betweenthe the outer sides of the bases of the rails.

Each of. these members is preferably in the term of a metal casting having supporting flanges 5 at the sides andvends thereof whereby each member assumes substantially the form of an inverted box. The top surface tends downwardly there-from between the sides thereof the lower edge being in a plane lower than the flanges 5. These partitions are adapted to be seated within grooves 8 provided in the topsurfaces of the ties and so located that when the parts are assembled the crossmg members will be heldagainst creeping laterally and thrusting against the sides of the rails.

The space inside of each of the crossing members is divided by obliquely disposed intersecting reinforcing ribs 9 the lower edges of which are in the same plane as the lower edges of the flanges 5. Each space within each member blocked off by these ribs 9 is provided with intersecting reinforcing fins 10 terminating in the angles formed by the ribs 9. These fins as well as the ribs 9 are integral with the crossing mcn'ibers. Adjacent each corner of each of the members 3 and 4 is an aperture 11 and similar apertures can be readily located along the longitudinal edges of the members, as shown at 11. These openings are designed to receive spikes 12 or other suitable fastening meansengaging the ties and whereby the crossing members are held securely in their proper positions between the rails. 7

By providing the arrangement of ribs 9 and fins 10 as shown and described, the crossing members can obviously support very heavy loads and'there is therefore no danger of these members collapsing. When it is desired to remove any one of the Inemupon the ties of a railway, intersecting re inforcing means integral with said member and surrounded by the flanges, and means integral with and projecting below the flanges of the member for engagement with the ties to hold the member against lateral creeping.

2. A railway crossing member including a top having side and end flanges adapted to rest upon the ties of a track, and means integral with said member and pro ec-ting;

therebelow for engaging the ties to hold the member against lateral creeping.

3. A railway crossing member including a top having depending side and end flanges, means carried by said member and extend ing therebelow for engaging the ties beneath the member to hold said member against lateral creeping, and means engaging said member forbinding the flanges upon the ties.

4:.A railway crossing member including a top having depending side and end flanges, means carried by said member and extend ing therebelow for engaging the ties beneath the member to hold said member against lateral creeping, intersecting reinforcing portions depending from the top of said member and between the flanges.

5. The combination with the ties and rails of a track, of a crossing member interposed between and abutting against the rails, said member including a top having depending side and end flanges resting on the ties, said ties having grooves therein, means depending from the top of the member and projecting below the flanges for engagement within the grooves to hold the member against lateral thrusting against the rails, and means for fastening the member to the ties.

6. The combination with the ties and rails of a track, said ties having grooves therein, of a crossing member at one side of each rail including a top, side and end flanges depending from the top, said flanges constituting means for engaging the ties to support the top substantially flush to the tops of the rails, means integral with said member and projecting therebelow adapted to be seated within the grooves to hold the member against lateral thrusting against the rails, intersecting reinforcing portions integral with the member and surrounded by the flanges, and means for fastening the member to the ties.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

ASA GILBERT FARWER.
