THOMAS W. TRAVIS, OF PHILADELPHIA, PENNSYLVANIA.

RAlLWAY-RAlL-SUPPORTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 224,808, dated February 24, 1880.

Application filed July 7, 1879.

To all whom it may concern Be it known that I,.THOMAs W. TRAVIS. of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Railway-Rail- Supporting'Deviees, of which the following is a specification.

I attain in the following manner, reference being had to the accompanying drawings, in

which-- Figure l is a side View, partly in section, of a portion of a railway-track with my improvements applied to the railway cross-tie for which Letters Paton t of the United States No. 214,208

were granted to me on the 8th dayof April,

A. D. 1879, Fig. 2 being a transverse section on the line 1 2, and Fig. 3 a transverse section on the line 3 4, Fig. 1.

A represents the rail, and B B flanged boxes similar to those shown in the aforesaid patcnt, these boxes containing clamps a, adapted to the flanges of the rail and having arms supported by wooden blocks bin theboxes ,wedgeshaped blocks in the latter acting on the arms ofthe clamps in a manner shown in Fig. 3.

Opposite boxes B are connected together by to said patent cost considerably-more than wooden cross-ties; and in order to construct or repair a road with my improved cross-ties at an expense but little it"any greaterthan would be incurred if wooden ties were used, I arvusual,.and support the rail at one or more points between the ties by means of a longitudinal girder, D. As shown in the drawings, this girder is made in the form of an arch, with strengtheningribs cl and projecting-lugs e 0, one on each side of the longitudinal center of thearch, the opposite ends of the girder restin g upon blocks f, ofwood or other elasticmaterial, adapted to suitable-sockets formed on the base-plates of the boxes B. By this means the rail is supported at three points, no as m, between each pair of boxes B, so that the latter can be set at a much greater distance apart than ordinary cross -ties without materially weakening the support of the rail, a less number of cross-ties being therefore used, and the expense of providinga road with the improved cross ties being correspondingly decreased.

I claim as my invention 1. The combination of a rail, A, and crossties or railsupportin g boxes B, with longitudinal arched girders for supporting the rail at one or more points*between said crossties or boxes, the ends of the girders resting at the bases of the boxes or cross-ties, as set forth.

2. The combination of the rail A and the boxes B, the girder D, and the elastic supporting-blocksf, as described.

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

THOMAS w. TRAVIS.
