RAIL SHOEA AND BRACE.

SPECIFICATION forming part of Letters Patent No. 511,170, dated December 19, 1893. Application filed August 26, 1893. Serial No. 484.109. (No model.)

To at@ whom 25 may concern:

Be it known that We, ANDREW B. SNIDER and WILLIAM H. ROBERTS, of Bartholows, in the county of Frederick and State of Maryland, have invented a new and useful Im-` provement in Rail Shoes and Braces, of which "the following is a specification.

The object of our invention is to provide a rail shoe and brace for holding rail road rails on curves so as to better resist the tendency of the car wheels to displace the rails laterally from the centrifugal action ofthe train, and it consists in the peculiar construction of a plate made in one piece and provided with spike holes for connecting it to the ties as will be hereinafter fullydescrbed.

Figure l is a plan View of a portion of a railway track showing our invention applied. Fig. 2 is an enlarged section taken through the rail shoe and brace transversely to the rail, and Fig. 3 is a plan view of the rail shoe and brace alone.

In the drawings A represents a metal plate having atone end a seat for the base of the rail, which seat is formed by an overhanginglip a at one edge, and a shoulder Z7 on the other side, the shoulder being formed by an increased thicknessofthe plate about its.

middle. The bottom 'of the plate is perfectly dat, but has at its end opposite the overhang ing flange a downwardly projecting sharpedged flange c whose outer face is at right angles to the plane of the plate, and whose inner face is beveled or inclined. Near the flange c there is a spike hole d, and at the edge of the seat for the base of the rail there are two other spike holes` e e which open through the shoulder l) so as to allow the head of the spikes to overlap and bear upon the base of the rail. v

When this shoe or brace is to beapplied, it is adjusted to the tie with the sharp edged ange c buried in the cross tie on the outer bend of the rail, and spikes are driveny through the holes d and e e which serve at the same time to fasten the shoe to the tie,

`and secure the rail in the shoe, the two spikes in holes e e serving in connection with the overhanging flange a to firmly hold the rail to its place in the seat. When thus adjusted it will be seen that the lateral strain of the train on the rail in passing curves is borne not simply by the spikes, but also by the flange c which is embedded in the cross tie, and a solid resistance or brace is thus afforded to resist such strain.

lVe are aware that it is not broadly new to provide a rail road chair in which the base of the rail is secured on one side by an overhangingliange and on the otherside bya shoulder and spikes as shown for instance in' expired Patent No. 15,036, dated J une 3, 1856. We are also aware that a rail road tie plate has been provided with a sharpened rib or I tie, as shown, Vfor example,'in Patent No..

485,030, dated October 25, 1892, and we make no broad claim to these features. Our invention is distinctive in the fact that the plate is extended a considerable distance farther on one side of the'rail than it is on the other, and the spike holes are exclusively in this extended side of the plate. This gives a better leverage to the plate for resisting lateral strain, and thespike holes are also widely separated, so that if the wood becomes rotten around one of the spike holes, the stability of the others is not impaired. Furthermore the sharp flange c being on the extreme outer `edge of the plate it catches the wood of tie where it is not perforated or irnpaired in strength by penetration of the spikes.

Having thus described our invention, what weclaim as new, and desire to secure by Let- 1. The rail shoe and brace, consisting of a plate having on one side a simple, imperferate, hook shaped rail-base flange a, and having'on the other side a shoulder h forming a rail seat vbetween them, with spike holes e e at the edge of the shoulder and opening into the rail seat the said plate being extended upon one side horizontally and provided with shown and described.

the plate `upon the saine side ot' the rail with plate substantially as holes e e substantially as and for thepurpose described. 2. The rail shoe and brace consistinfr of a 5 plate havingon one side an overhangingftlange l ANDREW B' HDER a, a thickened middle portion with shoulder CZ, l XVILLIAM H, ROBERTS. an extended side with a downwardly proj ec`t mark ing sharp flange c at its edge, spike holes e e vWitnesses:

extending through the shoulder Z), and a spike 1o hole CZ arranged in the extended portion of LEONARD O. MOKINZIE, WILLIAM B. HOOD.
