`Lotte/rs Patent No. 83,880, dated November 10, 1868; aatedcted October 28, 1868.

rMPRovED RAILWAY-RAIL.

FMH-

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, J Anus POTTER, of Portland, in the county of Cumberland, and State of Maine, have invented a new and useful Improved Railroad; and I herebyA declare the following to be a full, clear, and exact description thereof, which will enable others to make and use my invention, reference .being had to the accompanying drawings, forming part of this specification, in which- Figure 1, plate 1, is a side view of a portion of a railroad with the whole rail.

Figure 2 is a side view of the chair and base, show ing the manner in which the chair receives the joints of the base.

Figure', a sectional end elevation of iig. 1.

Figure 4', a washer for the bolts, to present a fiat bearing-surface for nuts. v

Figure 1, plate 2, is a top view of railroad with Adivided' rail: f

Figure 2, a side view of same.

Figure 3, aview of portion of top of chair, showing the slot for the reception of the securing-bolt.

My invention relates yto an improved method of constructing a railroad, and the following references to the drawings will serve to illustrate the same.

I use two kinds of rails, one whole, (see a,) and another divided, (see l1.) Yo are sleepers d, chairs; c, the base forthe rail or cap.

I will rst describe the chairs, and the manner of placing and securingthe same. These are bolted to the sleepers by screw-bolts f, inserted in the open space g,

and passing down into thcsleepers, and entering nuts h, placed in apertures in thel sleepers, as illustrated.

' These receive the screw-bolts, and thus bind thechairs to the sleepers. The' sleepers are further secured by means of"braces it. These braces are connected with the sleepers by means ofthe feet j, and with screw-bolts.

and nuts, in the saine manner as the chairs d.. The brace t, presses against the side of the rail by the feet k, as seen in ng. 3, plate 1. It, moreover, has the horizontal part, l, passing through a slet in the chair, and so constructed on the other side as to form the part, m. Through this is the screw-bolt n, with its base pressing against the outside of the chair. By turning the bolt n in the proper direction, the part, 7:, is brought close against the rail, the part, l, slipping through the chair. The foot j has a slot, o, to allow the brace to be adjusted to the rail, and thc foot is then secured by its bolt. Thus the brace fi is pressed rrnly against one side of the rail a.

e is the base for the'rail to rest on, and has the lip p to receive the other side ofthe rail, when tightened by the screw-boite, as first described. The bracefi binds both rail and base; t binds only the base, e.

The method of uniting the ends of the various rails' of this form of construction is ras follows: The clamp q overlaps the ends of the rails, and has bolts, fr r lr, passing down through the base, e, and there secured with nuts; alsoboltss s, Ste., passing horizontally through the rail, and secured with nuts on the oppo.

site side. At one-third the distance of the rails length, they are again bolted with a smaller clamp, in

the screw n, as before described, when the rails are held by lip p and the brace. At the joints of the divided rails, the clamp-bolts vare placed, down through the base, e, with nuts at the bottom ends. Horizontally through the'two parts of the divided rail are then inserted bolts w.

A is a washer, to hold the head of a bolt, being composed of two parts, 1, 2, with a disk of rubber, 3, being made to protect the boltheads, and to prevent entire rigidity when such is not desired.

4, plate 1, is a washer, placed under the rail, in the concavity thereof, to make a flat surface to receive the nuts of bolts.

The adjustable foot j may be secured to a stone sleeper, by simply reversing the bolt, and soldering it into the stone, and placing the nut over the adjustable foot and slot.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The chairs d, when secured to the sleepers c, as described, bybolts fand braces 'i i', as and for the purposes set foith.

2. The base, e, in combination with braces i i', part, m., and screw-bolt 11, as and for the purposes set forth.

3. The construction of the brace i t with projection m and slotted base j j', operating as described, on the rail and chair'.

4. The method of attaching the whole rail a to the chair, by means of base, e, braces i i', and clamps s fr t, constructed and combined as herein set forth.

5. 'The combination of the divided* rail l) with,A the.

base, e, chair d, clamps e yw, and braces 'i t, as and for the purposes set forth.
