RAILROAD TRACKAGE Filed Jari. 27, 1938 lNVENTOR l I FEEDER/C J CHEM/DL/N BY W Patented Nov. 29, 1938 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to a system of track construction for railroads, more particularly for use with scale model railroads. Heretofore the standard T-rail has been secured to cross ties with spikes or screw bolts. When small scale model railroads are constructed'these spikes and screws become so small that they are diillcult to handle and are inadequate to properly secure the track to the cross ties.

The object of my invention is to produce a new rail section and cross tie that will overcome all the above disadvantages and give a satisfactory railroad track that is inexpensively and conveniently constructed.

The foregoing and other features of my invention will now be described in connection with the accompanying drawing forming a part of this specification in which I have represented my rail system in a preferred form after which I shall point out in the claim those features whichI believe to be new and of my own invention.

In the drawing:

Figure I is a section of my rail.

Figure 11 is an isometric view of my cross tie.

Figure III is an enlarged detail showing how the rail is secured in the slot in the cross tie.

Figure IV is an isometric view of my track assembly.

In the carrying out of my invention I employ a T rail III the upper portion having substantially the proportional dimensions of the standard rail now in use in all railroads. Depending from the base II and integral with the rail is a web I2 approximately the same thickness of the web I3 of the T rail I0. I2, I provide an enlarged portion It.

In Figure I, I show this enlarged portion, shaped with barbs I5 on either side of the web I2.

Cooperating with my rail III I employ a plurality of cross ties 20. These ties are provided with two slots 2| having the same width as the On the lower edge of this web thickness of the web I2 and a depth substantially the length of the web extension below the base I I.

In Figure III, I show my rail III press fitted into a slot 2|, the fibers of the tie being deflected to permit entry of the enlarged end of 5 the rail l4 and when the rail is in its final position the fibers rebound above the barbs I5 to hold the rail firmly in the slot.

In Figure IV, I show an assembly of my track system. The rails III are spaced to a predeter- 10 mined gauge; the base II of the rail rests upon the upper face of the cross ties 20; the web I2 ils in slot 2| and held tightly in place by thebarbs While I have shown the enlarged outer edge I4 15 of the web I2 in the form of ablunt arrow head,

I do not wish to limit myself to that specific construction as any enlarged end would serve the purpose.

I wish it distinctly understood that my rail 20 track system is in the form I desire to construct it and that changes or variations may be made as convenient or desirable without departing from the salient features of my invention and I therefore intend the following claim to cover such 25 modifications as naturally fall within the lines of invention.

I claim:

In a small scale model railroad system, a track comprising a plurality of cross ties provided with 30 slots cut transverse the length thereof, a rail having a web projecting downwardly from the base of the rail and adapted to be forced vertically into the slots in the cross ties, said web having an enlarged end extending the entire length of the web, whereby the fiber of the tie having been longitudinally compressed temporarily while the rail is being inserted in the slot will return to normal, thereby gripping the rail and preventing its removal.
