Elm ra HURRY C. BUNNELL, OF WESTPORT, NEW YORK.

ARTIFICIAL-STONE RAILWAY.

Specification of Letters Patent. Patented Apr. 16, 1 918 Application filed February 18, 1918. Serial No. 217,833.

To all whom it may concern Be it known that I, HonRY G. BUNNELL, a citizen of the United States, residing at VVestport, in the county of Essex and State of New York, have invented certain new and useful Improvements in Artificial-Stone Railways, of which the following is a specification.

This invention relates to a rail formed of cement or concrete and designed to be laid on ties for the purpose of forming a railway for the use of automobiles, autotrucks or other forms of motor vehicles, either passenger or freight. The rails so formed will be especially useful in providing a durable trackway for heavy auto trucks employed for the hauling of produce or for logging use.

The invention consists in the novel features of construction hereinafter pointed out, shown in the accompanying drawings, and pointed out in the claim.

In the drawings:

Figure l is a plan view of a portion of a railway constructed from my rails, with a turn-out.

Fig. 2 is a vertical cross section through one of the rails.

Fig. 3 is a perspective view of one of the rails.

In the drawings 1 designates a concrete or cement rail provided with vertical side flanges 2, thereby forming along the longitudinal center of the rail a depressed treadway 8 in which the auto wheel runs. The rails, which may be of any desired length and weight, have drainage openings 4; fitted with metal cross bars or rods 4*. The rail 1 has also horizontal side flanges 5 and is reinforced with suitable wire netting 6. It is also strengthened by longitudinally eX- tending rods 7 which project from one end of the rail, as shown in F ig. 3.

At the end of the rail opposite the extending rods longitudinal bores 8 are formed which receive the extended portions of the rods carried by an abutting rail.

These rails are laid'on ties 9 in the usual way and secured by angled plates 10, spiked to the ties and extending over and bearing on the'flanges 5 of the rails.

One great advantage in rails of this character is that they are adapted to retain on the track the standard truck wheels now employed without requiring any change in the wheel construction or the application of any attachment to the wheel; a further ad vantage is that they are cheaper than metal rails; andmoreover they can be molded at or near theplace of'use so that it is unnecessary to ship them great distances. They can be placed in quickly up and down gra es for temporary use,-especially where construction Work is going on and trucks are being employed either for hauling dirt or'materials. They present a smooth firm roadbed forthe truck wheels andprevent miring in mud during bad weather or in low and swampy places.

What I claim is: v

A motor vehicle railway formed of concrete slabs, each slab forming a rail section and having a central depressed tread portion, vertical side flanges, and horizontal side flanges, tie rods extending from one end of each slab or rail, the opposite end having longitudinal bores, a wire netting reinforcement embedded in the rails and along its base portion, and angled plates adapted to be secured to a tie and to clamp the horizontal side flanges.

In testimony whereof I aflix my signature.

HORRY C. BUNNELL.
