PETER NELS MADSEN, OF SOUTH CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO LEO LA BEAU, OF CHICAGO, ILLINOIS.

RAILWAY-RAIL.

Specification of Letters Patent.

Application filed April 17, 1913.

Patented Nov. 1 8, 1913. Serial No. 761,658.

To all whom it may concern Be it known that I, Pn'rnn N. MAnsnN, a citizen of the United States, and a resident of the city of South Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Railway-Rails, of which the following is a specification.

My invention relates to railway rails and mountings therefor and the object of this improvement is to provide a railway rail and tie-plate arranged to hold a rail and prevent its turning thereon.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which- Figure 1 is a view, in perspective, of a portion of a railway rail and tie plate embodying my invention, and Fig. 2 is a transverse section of the same.

The preferred form of construction as illustrated in the drawing comprises a railway rail having the ordinary head portion 3 and shank 4t. The flanges 5 and (l of the rail are provided one thicker than the other and forming a beveled under surface of the rail. The lateral edges of the base flanges 5 and 6 are parallel and vertically straight.

A tie-plate 7 is provided with a groove corresponding to the cross-section of the flanges of the railway rail and of such a size and shape as will fit the flanges of the rail and prevent its turning thereon. Perforations are provided in the tie-plate 7 for conventional spikes 8 to prevent the rail from being raised vertically out of the groove in said tie-plate. The tie-plate is also provided with points 9 on its under side to prevent creeping of the tie-plate.

The railway rail and tie-plate as described herein is especially adapted for use on curves and where there is great side strain on the rail. The groove in tie-plate 7 is of such a size as to receive the flanges 5 and 6 of the rail substantially as indicated and in a manner to prevent the rail from turning on the tie-plate. The rail and tie-plate are designed to be set so that the greatest side strain will be applied in the direction of arrow 10 indicated in Fig. 2.

\Vhile I have illustrated and described the preferred form of construction for earrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modificatimis as come within the scope of the appended claim.

Having described my invention what I claim as new and desire to secure by Letters latent is:

In combination, a railway rail having base flanges with 'ertieally straight lateral edges, the lateral edge of one flange being considerably thicker than the lateral edge of the other flange and the under side of the rail being inclined dmvnward toward the thicker edge of such rail; and a tie plate having a groove therein snugly fitting the flanges on said rail and the inclined under side of said rail, substantiallv as described.

In testimony whereof. I have signed my name to this specification in the presence of two subscribing witnesses.
