v' IMPROVEMENT IN ELEVATED RAILWAY-S.`

Be it known that I, JAMES M. HANNAHS, of Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Elevated Railways, of which the following is a specification, reference being had to the accompanying drawings, in which-` Figure 1 s a side elevation, mounted on a series of single columns Fig. 2, an end view of the same 5 Fig.3, an end view, showing the waysvelevated; Fig. 4, an end view,mounted on two rows of columns; and Figs. 5, 6, and 7- are views of part-s detached.

M v invention relates to lelevated railways for cities, towns, parks, and like places; and consists of broad parallel girders, constructed, arranged, and supported, in connection with a railway-track, in a novel manner, upon a single or double row of columns, to form an in'- closure for the trac-k .and cars, as hereinafter explained. v I

In the drawings, A represents the metallic supporting-columns; B, the girders; C, the rails; D D D, cross-bars; E, floor or stringers; F, metallic cross-plates on arms of supporting-posts; H, flanged plates or an gie-irons riveted to the girders I, bolts for securing the girder-sections together; K, truss-rods; L, tension-rods or cables M, co1umns;`N, holsters; P, arched girder; a, base of supporting-columns; b, braces for side arms of c In the construction of this railway metallic columns A, made of suitable size and strength, with a broad. base, are placed on a stone or other suitable foundation. .When a single central row is used each column is provided with horizontal arms d, extending at right angles to the line of the columns, and at a proper height from the street,so as not to be anobstruc- They are made strong, 'and lnay be furtherstrengthened by braces b,'as shown, and

are' long enough to support a railway-track on On each of theseeachside of the columns. arms there are fastened plates F, bybolts or in any secure manner, and upon them are arranged two parallel lines of girders, B B,

with their ends meeting on the plates, and rmly secured to them. These girders have broad flanges on their under sides, and propart of Letters Patent No. 106,056, dated August 2, 1 870; 4reissue No. 6,1 50, dated V.November 24, 122174,: application filed `October 23, 1874.

. ject upward nearly to the top of the car-wheels,

as shown yin Fig. l, land theyare placed far enough apart to form an iron inclosure for a railway. These girders are also connected together by cross-bars D, which are placed at a proper distance apart to support a door`or the y track.

In one form of' the track the rails are bolted to the inner sides of the girders with a flange turned inward, as shown vat Figs. 2 and 7, and in the form shown at Figs. 2 and 3 the 'rails are bolted or spiked to the arms and cross-bars near the base-ilange fof the girders. To sup.- port and strengthen these girders when made of light material, l make va suspension-truss as follows: Connecting-plates H H, provided with flanges turned up, are bolted to the upper edge at the ends of each girder, as shown i-n Figs. 1, 5, and 6. They are drawn together by the bolts I, and these bolts, when tightened, serve to connect the girders .rmly,.so `as to form a continuous rigid line. Theplates on the two ends of each girder are then lconnected by truss-rods K, passing under the`cross-bars D, and arranged as shown in Fig. l. vThese rods may be tightened by any ordinary Lor suitable means.` As the girders are rigidly/connected' by the plates H, it will be seen that if one el' the truss-rods breaks the girder which it is 4mainly designed to .support will still be held securely at its ends by means of its connection, through the plates H H,'with the next girder and truss-rod. 0r, should agirder be broken or disconnected from' the plates H, vit would still be upheld by the truss-rods acting as suspension-cables.. These `gi-rders may also be further supported by tension-rods or cables L L,'stretched from or near the topsof `the columns M, which rise above the` main columns A, to cross-bars D under the girders, as shown at Fig. 1. The -girders maybe'further ysupported by holsters NN, restringen, or supported on, themain column A, and extending on eitherside at right langles to i't, and parallel with 'the girders, .as :shown by the dotted lines m, Fig. 1. These holsters have cross-bars D" bolted to the undersides of their ends,so `as to extend under `the main 'girders As the rails on which th'e-cars-runare placed next to yor near the innervslles of the girdcrs,

is obvious thatjth ese upwardproiecting gird- "--fl^ers,"fbesides furnishing theimmediate support of the railway, will also, by reason of their high sides, form an iron iuclosure, which will prevent the cars from. running oli' on either side, and form a guard or guide to keep the v cars on the track, as theears are made to t into the inclosur'e as closely asthey can he and avoid rubbing against the girders.

VVhe-n desired for usewin narrow streets, two rows of columns maybeQarranged as shown in l Fig. 4. In this case they are .placed along theouter edge of the opposite sidewalks, the columns opposite to eachother being connected byanarched vgirder, P, and chord f, connected with suitable tie-rods g, as shown in Fig. 4. The gir-ders B B and track are arranged 0u these arches substantially the same as when arranged on the side arms of single columns.

What I claim as new, and desire to secure by Letters Patent, is-- 1. The upward-projecting girders B B, sup- .ported upon elevating posts or arches, in combinatlon wlth the rails C, and arranged to form aninclosure to guard and support the cars, and prevent them from running o", substantially as specified.

2. An elevated railway mounted on a single column, or double row of columns, and consisting of the trussed girders B B, with the rail C attached,when constructed and arranged substantially as herein described.

3. In combination with girders Bv B, connecting-plates HH and the truss-rods KK,when constructed and arranged substantially as herein described, and for th'epurpose set forth.
