CHARLES J. BRBANK, OF ENID, OKLAHOMA,

RAILWAY-TRACK.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed Apr14, 1908. Serial No. 425,235.

To all whom it may concern:

Be it known that I, CHARLES J. BURBANK, a citizen of the United Statesresiding at Enid, in the county of Garfield and State of Oklahoma, have invented certain new and useful Improvements in Railway Tracks; and I do hereby declare the following to be a full, clear, and exact description of the invention7 such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to railway tracks and particularly to tracks designed for the running of motor vehicles having the ordinary construction of rubber tires.

The object of the invention is to provide a more economic construction of roadway or track on which such vehicles may be run, the intention being that motor cars shall be operated over this track to take the place of street cars or inter urban service.

The invention consists primarily in constructing the rails as well as the ties of concrete or other suitable composition instead of steel.

The invention also consists in the features of construction and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawing, illustrating the preferred embodiment of my invention: Figure l is a plan view of a section of track constructed in accordance with my invention. Figure 2 is a cross section thereof, and Fig. 3 is a longitudinal section.

In carrying out my invention, I first prepare a foundation l of broken stone about six inches in depth and extending below the rails 2. Said rails are preferably made of mixed concrete composed of Portland cement, sand and crushed stone formed in molds or in any other suitable manner. The body of said rails are preferably reinforced with metal rods 3 and each is provided with a flange 4 at its inner edge leaving a broad tread surface 5 on which the wheels of the vehicles are adapted to run. The foundation of broken stone is built vup to the surface of the road at each side of the rails as shown in Fig. 2. The treads of the rails are preferably arranged substantially on a level with the roadway while their flanges project upward therefrom. Cross ties or braces 6 are laid at the same time as the rails and are prefer ably made integral therewith. The foundation of broken stone need not extend below the cross ties as the weight of the passing vehicles will come wholly upon the rails. Said ties are also made of mixed concrete similar to that used in making the rails and they are also reinforced with metal rods '7. The ties are preferably arranged in the hori- Zontal plane of the rails, as shown. The ends of the reinforcing rods in the ties are extended into the bodies of the rails whereby said ties and rails are held more securely together.

In order to anchor the track to the road bed, as may be desirable in many cases, concrete posts 8 may be run down for a suitable distance from the track into said road bed. These posts or extensions are also preferably made integral with the rails and are located at proper intervals as may be required by the formation of the ground over which the track is built.

It will be observed that while the construction of railway track described herein is much cheaper to lay than the ordinary steel rails, it satisfactorily fulfils all the requirements for the purpose for which it is designed.

While I have illustrated and described herein the preferred embodiment of my invention, I do not limit myself as to details which may be changed without departing from the spirit or sacrificing the advantages of my invention.

I claim:

l. A railway track having composition rails and composition posts extending from said rails down into the road bed for the purpose specified.

2. A railway track having rails made of composition and laid upon a foundation, and composition posts extending from said rails through said foundation and into the road bed for the purpose specified.

3. A railway track comprising composition rails and composition ties both reinforced by inetal rods running longitudinally thereof.

et. A railway track comprising composie tion rails and composition ties7 the latter being reinforced with metal rods running longitudinally thereof and having their ends extending into the bodies of said rails.

5. A railway track comprising composition rails having their treads arranged substantially on a level with the roadway and flanges extending upwardly from said treads, and composition ties arranged in the horizontal planes of the treads of said rails whereby said ties do not project above the roadway, said ties being reinforced withl metal rods running longitudinally thereof and having their ends extending into the bodies of said rails.

6. A railway trackv comprising composition rails, composition ties, and composition posts extending from said rails down into the road bed for the purpose specified certain of said posts being arranged at the juncture of'said ties and rails.

71 A railway track comprising composition rails and composition ties both reina forced by metal rods, the reinforcing rods in said ties having their ends extending into the bodies of said rails, and composition posts extending from said rails down into the road bed for the purpose specied.

In testimony whereof, I affix my signature, in presence of two witnesses.
