JULIUS JONSON, OF NEW YORK, N. Y.

CONSTRUCTION OF TUNNELS FOR CABLE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 368,834, dated August 23, 1887.

Application filed February 8 1887. Serial No. 126.882. (No model.)

To CbZZ whom it may concern.-

Be it known that I, JnLius JoNsoN, of the city and county of New York, in. the State of New York, have invented a new and useful Improvement in the Construction of Tunnels for Cable Rail-ways, of which the following is a specification.

My invention relates to that class of railway structures in which there is a cable-tunnel of comparatively small size between the trackrails, and communicating with the surface by a narrow slot, which receives a connection between the car traveling on the surface, and mechanism for grasping the cable which moves in the tunnel. In such railways the trackrails are commonly supported by transverse frames or yokes at short intervals apart in their length, and at intervals in the line of the tunnel are pulley-vaults or sheave-pits, in which are arranged the pulleys or sheaves carrying a cable or cables.

The object of my invention is to provide a construction for such cable-tunnel and pulleyvaults that will permit of their being made v entirely or almost entirely of cast-metal plates which are substantially fiat or plane surfaces; and the invention consists in novel combina tions of parts which are hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a transverse section of a cable-railway structure embodying my invention. Fig. 2 is a horizontal section through the transverse yokes or frames and the side plates of the tunnel. Fig. 3 is a transverse section similar to Fig. 1, but taken through one of the pulley-vaults or sheave-pits. upon about the plane indicated by the dotted line 00 m, Fig. 3,-through one of the pulleyvaults or sheave'pits; and Fig. 5 is a plan View showing a cover or man-hole plate which closes a pulley-vault or sheave-pit and the means which are employed for supporting the same.

Similar letters of reference designate corresponding parts in all the figures.

A. designates the track-rails, and B the slotbars which are supported between them at suchadistance apart as to form the slot 1). The rails and slot-bars are supported at suitable intervals in their length by transverse frames or yokes, which are or may be of ordinary Fig. 4. is a longitudinal section form, and which are shown as consisting of up- I right stands or castings G, securely riveted or bolted at proper distances apart in the length of a transverse beam or girder, O, which may be in the form of an I-beam, as shown in Fig. 4.

The tunnelitself I have represented as composed of side plates, D, and bottom plates, D. All these plates are substantially flat, and they are provided with strengthening-ribs d on theirsurfaces, as shown in Figs. 1 and 2. The several plates D D are constructed so as to form rabbeted joints with lateral flanges c on the transverse yokes or frames, and the side and bottom plates are rabbeted or constructed to form rabbeted joints one with another, as shown in Fig. l, the side plates, D, being rabbeted at (P, so as to form suitable joints with the bottom plates. The side plates, D D, may extend-upward to the slotbars B, as shown at b.

The several plates D D of which the tunnel is composed, being made substantially flat and of cast metal, with strengtheningribs upon their surfaces, they may be arranged and secured together to form the tunnel E with the least possible labor, and without the necessity of leaving the street or excavation open for a long time in order to enable cement or masonry to become properly dried before being covered with earth. The plates being pro vided of proper size, they can be arranged in place and secured together to form the tunnel E almost as-rapidly as the excavation can be made, and in building the structure the least amount of interference with surface travel will be created. 7

In Figs. 3, 4, and 5 I have represented a pulley-vault or sheave pit such as will be constructed at suitable intervals in the line of the tunnel, and which is designated by the letter E. The ends of this pulleyvault or sheavepit E down to the level of the beams C may be formed solely by the transverse yokes or frames 0 O, as best shown in Fig. 4, and the longitudinal walls, or those walls of the vault which are lengthwise of or parallel with the track-rails A, may be formed by upper plates, D and lower plates, D, as is shown in Fig. 3. The plates D are here represented as secured at b, respectively, to one of the'slotbars B, and also to the transverse frames or yokes G 0, formed on opposite walls of the pulley-vault. The plates D D are provided on their surface with strengthening-ribs d, and one or both of them are bolted to flanges 0, projecting from the transverse yokes or frames 0 O, asis shown at thelefthand of Fig. 3. The lower plates, D, which form the longitudinal walls of the pulleyvault, are united. by rab beted and bolted or riveted joints d with the upper plates, D", as shown in Fig. 3, and the lower end plates, D", forming the lower portion of the end walls of the vault, may extend only to the transverse beams or girders C, as is shown in Fig. 4, and may be bolted or riveted at d to the plates D which form the longitudinal lower walls of the vault.

The bottom of the vault is formed by a plate, D which is constructed to form a rabbeted and bolted or riveted joint 61 with the longitudinal side plates, D and the end plates, D", which form the lower portions of the walls of the pulley-vault. Each pulley-vault has aman-hole at the street-surface, which is closed by a cover, F. This cover may be supported by transverse bars or bearers F, one of which is shown in Fig. 5 and both of which are shown in Fig. 4, and these transverse bars or bearers may extend from one of the slot-bars 13 to the track-rail A, which is upon the same side of the slot, and form an adequate support for the man-hole cover F. The space between each of the transverse bars or bearers F and the transverse yoke or frame 0 G which is nearest adjacent thereto may be closed by a plate, F which rests upon the top of the trans verse yoke or frame and also upon the ledge or shoulderf, provided on the adjacent bar or bearer.

It will be readily seen that I provide for constructing the pulley-vaults in the same simple manner as the tunnel proper, and the plates for both these purposes having been previously made in proper sizes and shapes,

maybe secured together and the structure' completed almost as rapidly as the excavation can be made.

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

1. In a cable-railway structure, the combination, with the transverse yokes or frames for supporting the rails and slot-bars, of a tunnel composed of substantially flat base and side plates ribbed upon their surfaces and secured together and to the said yokes or frames, substantially as herein described.

2. The combination, with the transverse yokes or frames for supporting the rails and slot-bars, of a tunnel composed of substantially flat plates ribbed upon their surfaces and forming rabbeted joints with the yokes or frames and with each other, substantially as herein described.

3. The combination, with the transverse yokes or frames for supporting the rails and slot-bars, of a tunnel and pulley-vaults at intervalsin the length thereof, both formed of substantially flat plates ribbed on their surfaces and forming rabbeted joints with the yokes or frames and with each other, substantially as herein described.

4. The combination, with the transverse yokes or frames supporting the slot-bars and rails, of the transverse bars or bearers F, extending between the slot-bars and one of the rails, the man-hole cover F, supported on and between said bars or bearers, and the plates F for sustaining the road-bed, supported on said bars or bearers and the adjacent yokes or frames, substantially as herein described.
