IMPROVED RAILWAY-CHAIR.

@Ligt Stimme infermi tu in time @titers ahnt ath making part at tigt :stmt` To ALL WHOM IT MAY CONCERN: i Be it known that I, JOHN H. DOWNING, of Salem, in the county of Essex, and State of Massachusetts, havel invented a new and useful Improvement in Railroad-Chairs and Rails; and I do hereby declare that the fl- 4lowing is a full, clear, and exact description thereof, which will enable others skilled invf the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification;

Figure 1 is a cross-section of my improved double-lap rails and chairs.

Figure 2 is a top view of the same.

Figure 3 is a modihcation of the rail.

Similar letters of reference indicate corresponding partent This invention relates to an improvement in the construction of railroad-rails and chairs, and consists in forming the rails in two parts, to lie side by side, with lap-joints combined with `narrow chairs, having single heads placed on each side ofthe rail to clamp thetwo parts together firmly at the joints, and fasten them to the ties, as hereinafter more particularly shown and described.

The rail is made in equal longitudinal sections a a, joined vertically. 'I he sections lap to form break-joints, as shown in tig 2. They are held togetherlandlsecured to the ties by narrowsingle-headed chairs A, which are placed with their heads c on opposite sides ofthe rail. bearing on and clamping the base rmly, with one spike only at each end of the chair. The spike-hole, at the head of. the chair, is made at an angle wthrthe bottom, to drewA the head against the rail, and thus the two single-headed chairs, bearing on opposite sides, will clamp and bind the sections a a'together irmlyfdispens-ing with wedges used with` the ordinary double-headedchair. The spike-hole at the other or smaller end of the chair is made straight, as shown in fig. 1.

In laying rails, a singlefrow of chairs, with their headset' on one side, are fastened first by spiking in the straight hole, and the rails being then laid in place against the heads, the chairs-with heads on the opposite side are fastened by spiking rst through the hole at the head, which, boing set at an angle, binds the Whole together irmlywithout employing a. wedges' A common rail may be united at the ends with -a. scarf-joint, as shown in g. 3, and be fastened with my 'single-headed chairs to be perfectly secure. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The single-headed chair Afin combination with a'sectional'railroad-rail, arranged as and for the purpose shown and described.
