T Q; all whom/t may. concern:

',gBeL it known that l, JOHN FRANKLIN LEWIS, a citizen of the UnitedStates, residing-at Kansas City, in the county of Wyanhave invented a' useful Railway-R ail Chair, of which new and the following is a specificatmn. This,l invention relates to railway rail chairs-'and its-Objectis to lprovide simple yand e rails can be supported upon the ties vor sleepers and secured thereto.

A still further object is to provide bracing means of novel form for use upon curves or 1 5 wherever the rails are subjected to lateral or side ressure.

A sti further object ist'o provide a com,- bined chair and brace which 1s simple, duran `ble and efficient in construction and which -20 can be readily placed in position.

With- 4these and vother objects in view the invention consists of certain novel features `of construction and combinations of parts lwhich willbe hereinafter more fully described the claims.

'In the accompanying drawings is shown the preferred form of the invention.

In saiddrawings: Figure- 1 is aplan vi'ew of the chair and brace embodying the present thereon; Fig. v2 is a longitudinal section through the chair and brace, 4the rail being shownin transverse section; and Fig. 3 'is a detail view of one end portion of the chair. characters of reference, 1 designates the base plate con- -stitutinv the chair proper .and this plate is 'designe vto be fastened to a tie 2 by means of .spikes as ordinarily. The plate is thickened at the center and provided'in its face with a broad rail receiving groove 3 one wall of which is undercut as shown at fi so as to lap the inner base flange of a rail and prevent it from tilting outwardly when to a side pressure. A part of the 3 extends above t e adjoining base flange of the rail as shown at 5 and constitutes an abutment-for the urpose hereinafter disclosed. The rail,

upper which has been indicated at 6, is held within the groove 3 by means of spikes 7 which ex-l tendthrough the plate 1. These spikes are ,so located that the heads thereof will lap the base flanges of the rail 6 and hold said rail 55 firmly within the groovel 3.

Along straight stretches of road the fasiail be1ng shown in position l Y tening means above described willbe found sufficient to hold the rails securely in place but where the rails are dis osed along curves l they are preferably provi ed with braces for l the purpose of preventing them from tilting l and slpeading apart when subjected to the side t i of a 'car when roundlng a curve. Each of these braces is formed preferably ina single casting and' comprises a body 8 shaped' tot snugly u on one ofY the base flanges an l against t e'web of the rail, the upper end of the body bearingagainst the lower faceof the rail head. A- shoulder 9 extends transversely along the lower face Vof the brace-and is desi ned to bear a ainst the abutment 5y so that a ter the brace as once been placedin position vthe shoulder and abutment serve to old it against displacement. Webs 1() are edgesthereo anda bolt opening 11 is formed in said body andfis 'designed to register with van openingl12in the base plate 1.y This o ening 12 is disposed to receive an angular bolt 13 the threaded portion of which projects through the opening 11 and between the Webs 10 andis `a apte to be engaged by a nut such as shown at 14. By serewin this nut onto the bolt lthe brace will be mly clam ed upon the plate 1 and the shoulder .9 he d positively against the abutment 5. The brace-will obviously resist any lateral pressure which may be exerted a ainst the rail and therefore the spreading o the rails will -be effectually prevented. The bolt opening 12 is referably counterbored as at 15 to receive t e head of the bolt and permit the'plate 1 to rest flat upon the tie. Not only does the brace 8 serve to uphold the rail against lateral pressure but also co crates with the fasteners 7 for the purpose o securinv the rail within the groove 3.

at is claimed is 1. A rail chair comprising a base plate having .a rail 'receivin groove in the upper face thereof, one'wal ofthe groove being disposed to lap one base flange of a rail, the

a portion of sai perpendicu ar wall being extended upward to constitute anabutment, a brace dis osed to lap the roove and bearing u on .t e extension, sai shoulder disposed to bear against the abutment, and means extending through the extension and brace for securing the brace upon the extension.

ust or pressure exerted by the wheels formed inte ral with the body at the side other wall of said roove being 1perpendicular, V

brace`-having a 2. The combination with s l eeen-ie ing a groove in one face thereof, one Wall of the A groove being other Wal] being un ercut; of a rail inserti-- 5 ble' downward into l y engagementwith erpendicular and the the groove and into the undercut Wall of the groove and against the perpendioularwall,

an extension upon th e'base and above said perpendioulai. Wall, said extension consti- 10 tutlng an abutment d flange of the rail, a br isposed above the base ace bearing against the a base piate havi rail and u on the extension, saidfbmcehave ing a shou der bearing against the affm-txiierit,

and means extending through-the base" plate
