IMPROVEMENT IN RAILRGAD-CHAIRS.
Specification forming part of Letters Patent N 0. 144,332, dated November 4, 187 3 application filed September 18, 1873.
To all whom it may concern: ing in form and size. The ends of the rails are Be it known that I, DAVID M. GRAHAM, of constructed with the slots 0, which, when the vansvllle, 1n the county of Vanderburg and rails are in position, together form an oblong State of Indiana, have invented an Improved aperture, corresponding with the apertures b Railroad-Chair, or J omt-Supporter, of which in the chair, so that when the chair is in posithe following is a specification: tion, with the ends of the rails B passedtherein My mvention relates to devices for securing the keys 0 D may be passed through the railway-rails in position; and consists in cerwhole, as indicated in Fig. l. g are niches in tain improvements and novel construction of the base of the rail, of the usual construction, parts, the rails at the joint being provided the same being formed to receive spikes, so with a chair or joint-supporter, which clamps that the rail can be rigidly fastened to the them, and by means of eys passed through ties, to prevent shoving or crawling of the specification thereof, Figure 1 is a top view of view. Fig. 4 represents the bottom of chair.
.Fig. 0 represents the keys.
' Fig. 4. The chair has also two mortises or obapertures and slots in the chair and rails, the rail. The chair or joint-supporter is adjusta latter are held firmly in place without any ble,be1ng made in two dlVlSlODS, as shown, rigid attachment to the chair, as heretofore.
In the accompanying drawing, which illustrates my invention anl forms a part of the pass within each other, forming alock beneath the rail in the chair. The keys 0 D, having the shoulders e f, are passed from opposite sides of the joint-supporter through the opening formed by the oblong aperture 1) in the chairand the slots 0 1n the ends of the rails,
rails with my invention applied thereto. Fig. is a side view of same. Fig. 3 is an end Fig. 5 r presents the ends of rails in position. v The object of this invention is to provide a chair or joint-supporter for the rails, by means of which the rails are securely held in position without any rigid attachment to the joint-supporter, and, at the same time, the rails are allowed to expand or contract without damage or displacement from the running of the cars. In the drawing referred to, letter A desighates the chair or joint-supporter, constructed to inclose an end of each rail at a joint, and to clamp the rail about the sides and base, as shown in Fig. 3. The said chair is made in two parts, the division being in the base, where the two parts a are beveled, and formed so that each extends within the other, as shown in Having thus described the construction and operation .of my invention, I will statewhat I claim in the following clause:
apertures 11 and beveled parts a, in combination with keys 0 and D, and slots 0 in the ends of the rails, substantially as and for the purpose set forth. I
