CHAIR FOR RAILROADS. l

Specification of Letters liatent N 0,

scription thereof, reference being had to the accompanying drawings, making part of thls specification, in wh1ch Figure 1, 1s a cross vertical section taken in the plane of the junction of the rails;

Fig. 2 a side elevation of the rails in the chair; Fig. 3, a section taken in the central longitudinal plane of the rails; Figb a plan of the rails, chair and sleeper.

The same letters indicate like parts in all the figures.

The object of my said invention is to secure the junctions of the sections of rails so as to insure the retaining of them in line, and to this end my said invention consists in the employment of a chair with lips to extend over the web or base of the rail, and

with a grooi e or other suitable receptacle for a cross wedge which is to be used in combination therewith, and which is to be driven across the longitudinal plane of the rail and just under the base of the proximate ends of two sections so as to force the webs of the said rails up against the two lips of the chair, and at the same time to form a base for them to rest on, whereby I am enabled to keep the proximate ends of the sections of rails in line and on the same level, and avoid that hammering actlon whlch 1s so 1n ur1ous to rails, and all the other difiiculties consequent upon the use of imperfect modes of securing the ends of rails in chairs.

In the accompanying drawings (A) represents the chair, which may be secured. in any suitable manner to the sleeper or cross tie (D)- This chair is formed with lips (b, b) to extend over the web (0, c) or base of the rails (B) while the under surface of the web or base rest-s on the flat surface of the chair between the lips. I prefer so to form the under surface of the lips (b, b).

that they shall fit the upper surface of the web (a, c) of the rails. The upper surface of the base of the chair, on which the base of the rail rests is formed with a groove (0?) at right angles with the longitudinal plane the two lips (I), b) ofthe chair and slotting 26,492, dated Dec mbrao; 11859.1 :1, w
