ELEVATED RAILROAD.

SPECIFICATION forming part of Letters Patent No. 859,758, dated March 22, 1887.

Application filed April '3], 1886.

To ctZZ 1071,0727, it may concern:

Be it known that I, Rnynoiins T. Wnrrn, a citizen of the United States, residing; at Boston, in the county of Suffolk and State of Massachusct-ts, have invented a new and useful linprovenientin Elevated Railroads, of which the following is a specification.

My invention relates to certain improvements in elevated railroads to be supported upon a single line of columns or posts; and the invention consists in the construction and arrangement of parts, as hereinafter fully described, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side elevation of an elevated railroad and car embodying my invention. Fig. 2 is a transverse section of an elevated railroad and end View of the car drawn to a large scale. Figs. 3 to 10 are detail views of various parts. Fig. 11 shows a modilieation of the track and bogiefiaine. Fig. 12 is a vertical section showing the means for securing the columns or posts in the ground. Fig. 13 is aplan View of the switch end. Fig. 14 is a side elevation of the same, partly in section. Fig. 15 is a vertical section of the switch, taken on line :0 at of Fig. l i.

A represents the columns or posts, upon the top of which is secured the main girder B, which is composed of two wrought iron plates, a. a, secured together by transverse plates 0 I) (see Figs. 3 and at) at intervals of, say, fifteen inches apart; but they do not extend the full depth of the plates (6 a, (which latter are curved on their upper edges.) The plates D Z) are all of the same depth, so that their upper edges are on a level with each other, and to which the main rail 0 is secured.

D D are box girders supported from the columns or posts A by brackets E, and also from the main girder B by intermediate brackets, E. On the top of the box-girders D are secured flat rails F.

a: 10, Fig. 2, are plates secured to the outside of the girder B, and form a i'ootway, so that a person can walk along to examine the track.

Serial No. 199,6F2. (No mrdel.)

The truck or bogie frames that carry the car G consist of a flat plate, H, fronrwhich depend two brackets, I, provided at their lower ends with bearings for the axlej of the main wheel J, and above the plate H is a circular track, K, supported by brackcts'from the plate H.

On each corner of the plate H is provided a guide or steady wheel, L, that runs against flat rails 7t 7t, secured to the inside of the boxguidcs D, and also a small roller, M, that runs under the bottom of the girder D.

N is a circular plate secured to the under side of the car G, and provided on its under side with springs in m, that bear on the track K, and also with rollers n n, that are free to travel in the circular track K when the load of the car is so great as to cause the springs in m to yield suiliciently for them to conieinto contact.

From the upper surface of the plate N pro jects a flange, 1), in the center, that forms a complete circle, and also on the upper surface, at its edge, there is a flange, g, which does not pass entirely around the plate, an opening be ing left in that part of the flange toward the end of the car.

The truck-i'ran'ie is secured to the car by means of a bolt, V, so that the frame is free to turn in any direction.

1? represents a draw-bar, as shown in Fl 10, provided at its inner end with a circular opening, Q, which is of such size as to fit over and work around the central flange, 1), on plate N, so that when the plate N is secured to the bottom of the car the draw-bar P will be held in place, and the lateral play of the bar will be limited to the space between the ends of the flange The outer end of the draw-bar is provided with any suitable coupling, It.

S S are wheels secured to the sides of the car by bolts passing through plates T and hoods U. These wheels are to assist in carrying the weight of the car. The wheels L, as shown in Fig. 9, have a metal body, 1', with a bearingsurface, s, of wood, made tapering toward the center of the wheel, so as to be firmly held by the ring t, which is secured to the body aby bolts to. I also cover these wheels with hoods, so as to protect them against snow. As each truclrframe is carried by one main wheel, J, and is also provided with the four wheels L, that bear at each corner against the box-girders D, and is also provided at each cornerwith rollers M, that run under the girders D, it will be impossible for the main wheel to leave the track, while at the same time it can pass around curves of very short radii, and the car itself is kept from swaying from side to side by reason of the wheels S running on the rails F; and, further, as the draw-bar I? is secured to the flange p, the draft is from the center of the truck-frame and not from the end of the car, as is usual.

In Fig. 11 I have shown a modification, in which the wheels 8, that travel on the rails F, are secured to the truck-frame and not to the car itself. Consequently the box-girders D are not so much above the main rail as in Fig. 2. Otherwise the parts are the same. The wheels S S are also shown in dotted lines in Fig. 5.

The columns or posts A are secured in the ground in the manner shown in Fig. 12, in which IV represents the ground; X, a wood or metal pile driven therein to about a depth of, say, eighteen feet; and Y is a metal plate let down, say, about eight feet from the surface, and upon which the post A is plaoed,with the pile, which projects above the surface, say, ten feet in the center. The space between the pile and post is then filledin with concrete Z, and concrete Z is placed around the outside of the post for, say, eighteen inches.

Figs. 13 and 14 show the switch, 0 being the main rail, which at 0" branches off in two directions, 0 C the portion of the rail at C being made similar to an ordinary frog. The box-girders D follow the same line or inclination as the rails (3 O and at the j unotion D of the two inner box-girders D there is a post, A to which their ends are secured. The upper end of the post A is made round and carries the switch D which is made of the shape shown and of the section shown in Fig. 15.

On the top of the switch isaplate, F, of the full width of the switch and corresponding in thickness with the rails F on the girders D.

The end. of the plate F projects beyond the switch and is out 01f at an angle, so that it will come in contact with the rails F. The switch is secured to the post A in the manner shown in Fig. 14, in which the rear end, D is made with a recess that fits over the top of the post A*, and is secured to it by a bolt, D. The projection D at the lower rear end. of the switch is made circular, so asv to tit and work handle of the crank f is turned in one direction or the other, so will the switch be thrown to one side or the other to guide the ear onto the desired track.

A small roller or wheel, h, is secured to the under side of the switch, and runs on a girder,

i, secured between the two girders B B. By

means of this roller h the switch is moved very easily, as it acts as a fulcrum, the weight of the switch being equal, or nearly so, on each side.
