CONSTRUCTION OF RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 271,727, dated February 6, l83.

Application filed November 7, 1881. (No model.)

To all whom it may concern:

Be it known that I, DANIEL J. MILLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Construction of Railways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of railroads in which the cars are propelled by a cable or chain and it consists in an improved construction ofthe road-bed or tunnel in which. the cable travels, and a combined cable-support and'cable-lifter.

My improvement in shunting devices, heretofore described, being a separate invention, I reserve the same for another and separate application.

The object of my invention is to simplify the construction of road-bed, make itstronger and more durable, and also have the cable'supports (or carrying-pulleys, as they are usually called) so arranged that the cable can be raised sufficiently to be received into the gripper at any point on the road.

Figure l is a cross-section of track. Fig. 2 is a plan and section on line C 0' of Fig. 1. Figs. 3 and 4 are side elevations of combined carrying-pulleys and cable-lifter.

In Fig.1, T represents the tunnel; V, the opening through the surface of the street into the tunnel T. Z Z represent the track-rails; S S slot-rails for forming opening V. B B represent brackets for supporting slot-rails S S and track-rails Z Z, and also holding them firmly in place. G represents an iron girder, for which any form of iron may be used; or ordinary wood ties will answer the purpose, if necessary. W W represent brick wall for forming the tunnel, and serves as afoundation for iron-Work ot" the road. D D represent carrying-pulleys, which are also used as cablelifters. These pulleys are placed in frames H H, said frames H H provided with a rockshaft or hinge at t and having a positive rest at E B. As the cable is always moving in from gripper on the route.

one direction, it. has a tendency to keep the carrying-pulleys I) D in position. Two of these pulleys are connected by means of a chain or rod, N, at such points in the road as it may be necessary. to pick up a cable, butare used separately and without rod or chain N when used merely for carrying-pulleys for cable, although the pulleys may be used singly.

to raise the cable it it (the cable) should be 10st The line of cable when in gripper is generally from eight to nine inches above its regular line when running on the pulleys D I). Some grippers are so arranged that if they drop the cable there is no way of picking it up, but with my carryingpulleys the operator has only to step back of his car, reach through slot V with a small \vire having a loop on one end, andhook onto frame H at P, and, with a vertical lift, frame H will swing at t, and raise the cable to dotted line M, when it will run into the gripper.

What I claim as new is the combined cablesupport'or carrying-pulley and cable-1ifter,'by having said carrying-pulley set in a frame which is attached at one end by a hinge or rock-shaft that said frame may be vertically oscillated for the purpose of raising the cable that it may be received intothe gripper.

Brackets B B and tie G, when riveted together, are called yokes. These support the iron-work of the street, and it is important to have the slot V of uniform width and at a given distance from track rails Z Z. With roads constructed heretofore the yokes have been made of several pieces in order to adjust slotrails. This makes an expensive construction, as all the small pieces have to be manufactured separately, and adjusting work in the street makes a great amount of unnecessary labor. In manufacturing my yoke I purpose to have the tie G drilled for rivets R BER, and as all these ties are drilled from the same gage they are exactly alike. All brackets B B are cast from the same set of patterns, and holes for rivets It R It R drilled from one gage, using faces F F as workingpoints. When these brackets and ties are riveted together the faces F F will be uniform, thus saving a large percentage in construction of road-bed by dispensing with adjustment of slot-rails in the street and having positive points from which to work.

I have here represented slot-rails of differentshapes; but my invention relates to no particular form,as almost any shape may be used.

Brackets B B are cast with flanges A A A A, which forms a chair for stringers and trackrails Z Z. It has been customary to cast these chairs separately and bolt them to the'yoke, but to insure accuracy in work there should be as few pieces as possible, and I purpose to bolt slot-rail to the same casting that forms chairfor holding stringers and track-rails Z Z. By doingthe work in this mannerthe track will be-of uniform width and slot-rails in center of track, and in this way the road can be built much cheaper, as all adjustment is dispensedwith, excepting what is done with the wooden wedges on either side of stringers, and when the road is put together in this manner it is solid and cannot getout of place.

Brackets B B are cast with an extra flange,

L L, to support the side pieces, S S, of tunnel, and the yokes are placed from four to tire feet apart. I place planks or sheet-iron ot' aboutlhe length of distance between the yokes, with the ends of said planks or sheet-iron resting inside the flanges L L, thus inelosing the tunnel. hen putting the work together in the street the channel is excavated the width of the brick walls, and these walls laid the height of tie G, after which the yokes are placed in position and groove-rails put on and bolted to the yokes. The sidepieces are then putin place, which incloses the tunnel. Bya little lateral adjustmentot' the yokes to line up the slot the road is ready for track-rail and paving. With this construction each class of men have their work separate and can work to advantage, when with nearly all other constructions the iron-workers, masons, and finishers are obliged to do their work atthe same time, creating confusion and working to great disadvantage.

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

1. Theyoke composedot'girderG and brackets B B, on which lugs A A A Afor chair are cast, said brackets being firmly secured to girder Gr, all for the purpose specified.

2. The brackets B B, having chair-lugs A A cast on one end and slot-rail faces on the other, for the purpose'specitied.

3. The bracketB, forminga chair for stringer and track-rail and a support for slot-rail, combilled for the purpose specified.

t. Brackets B B, having projections or flanges L L, for the purpose specified.

5. In a cablcway, the combined cable-support and cable-raising pulley D, mounted and operated as and for the purpose set forth.

6. The two carrying'pulleys D D, mounted and hinged, when connected by a chain or rod, as shown, to insure their being simultaneously raised, for the purpose specified.

7. The combined carrying and cable raising pulley I) 1), provided with seat E E, for the purpose set forth.

In testimony whereof I atfix my signature in presence of two witnesses. I

DANIEL J. MILLER.
