SPECIFICATION forming part of Letters Patent No. 379,181, dated March 6, 1888. i Application filed December 24, 1887. Serial No. 258,891. (No model.)

To all whom tmc/.y concern:

Be it known that I, D. DEAN READ, of Boston, county of Suffolk, State of Massachusetts,

'representing like parts.

My invention relates to an elevated-railway structure composed of trusses supported on suitable columns or uprights above and below the cars, which have trucks above and below eno-operating with rails on the upper and under trusses, substantially as shown in Letters Patent No. 373,605, granted to me November 22, 1887, to which reference may be had. i

The present invention consists, mainly, in details of construction of the trusses and rails by which angle-iron and rails of usual shape may `be employed throughout the structure without requiring the rolling of the special shapes, as in the structure shown in the patent referred to.

The present invention consists, mainly, in progiding the top flange of the'lower truss and the bottom flange of theupper truss with lateral arms, on which are supported railwayrails of the usualT shape, which rest on longitudinal supports between the said lateral arms, and, when required, may be stifened by secondary trus'sing.

The invention also consists in various other details, which will be hereinafter pointed out.

Figure l is a side elevation of a portion of portion of the upper truck; Fig. 9, aside elevation of a portion of the upper truck, and Fig. l0 a plan view oi' a portion thereof.

4The general arrangement of the structure, consisting of uprights or columns a, extended erate with the said columns to support the lower or main truss, d, andA upper truss,f, is substantially the same as in my patent hereinbel'ore referred to.

In the present invention the upper chord, d', (see Figs. 4, 5, and 6,) of thelower truss hassecured to it from point to point along its length transverse arms or cross-pieces g, which inV turn support at their ends longitudinal beams h, on which rest the rails i, which are of the usual T shape.

The crossl pieces g are provided at their ends with ears g', that engage the lianges of the rails z', which are securely fastened upon the beams h by clamp-pieces 7c, bolted to the said armsg between the rails and the central truss, d.

The outer ends ofthe cross-piecesg are supported by braces m, extending to the lower chord, di, of the truss, as shown in Fig. 4. Longitudinal pieces of angle-iron, n, are fast ened to the upper ends of'said braces, the

lower edges of which pieces ot' angle-iron cooperate with guard-wheels n/,connect'ed with braces n2, extending downward from the carbody andserving to prevent the cars from overturning in ease an accident should occur to the running-gear at the top of the car. The strips n also contribute to the support of the beams h and rails 1lV thereon.

The rails i are ofcomparatively narrow gage, and are not depended upon solely to afford sufficient stability for the running of the cars, which are retained in their upright position or prevented from overturning by the upper truss, f, (see Figs. 7 and 8,) the lower chord, f', of which is provided with crosspieces g2, having at their outer ends upturned projections g3, to which are fastened longitudinal beams 71,', on which are supported the rails i', which cooperate with the trucks or hangers at the top of the car-body, as shown in Fig. 2.

The arms g2 are strengthened by bracesm,"

extending to the upper chord of the upper truss, and the rails i arefastcned by clamps k', bolted to the said cross-pieces g2.

' The upper trucks or hangers may consist of double-flanged wheels o, (see Figs. 8 and 9,) journaled on yokes o', as shown in Figs. 9 and 10, swiveled upon rods o2, having an enlargement at the lower end, as shown in Fig. 9, by which they are fastened in suitable sockets connected with the frame-work at the top of the car.

The lower trucks consist of a framc,p, (see Fig. 6,) swiveled upon the car-body and provided with bearings p for the journals of the axles ot the wheels pt, which may have a single inner flange, as in the usual railway construct-ion.

The wheel-base aftorded by the lower track,- t', is suicient to support the cars, and may be depended upon aloneas shown in Fig. 3, at switches or places where it is desirable to discontinue or form a break in the upper truss, which affords additional stability in the main part of the track, so that the cars may run safely at high speeds.

Vhen required, the rails i and t" may be stiffened by secondary trussing, as represented at t, Figs. l, 4, 5, and 7, consisting of tie-rods fastened to the lower flange of the beams h and h.

The upper chord, d', of thelower truss may also support a longitudinal box or trough, a, composed of angle-iron, for the purpose of inclosing and protecting a propelling-cable, w, supported on friction-wheels w', having bearings in the sides ofsaid trough, and thelower chord of the upper truss may be provided with a box, o, also composed of angle-iron, as shown, in which is inclosed an electric conductor, c, which may be employed when the cars are propelled by electricity.

I claiml. An elevated-railway structure comprising a supporting-truss centrally located below the ears and having its upper member provided-with cross-pieces supporting longitudinal beams and T- rails thereomcombined with au upper truss provided with rails, the said upper and lower trusses co operating with cars having trucks above and below eo-operating with said rails on the upper and lower trusses, substantially as described.

2. An elevated-railway structure comprising a truss beneath the cars having on its upper melnber cross-bars and rails supported at the ends of said cross-bars, combined with a longitudinal trough supported on said truss between said rails, substantially as and for the purpose described.

In a railway structure, a truss centrally located with relation to the cars, having one of its chords provided with cross pieces and rails supported at the ends ofsaid cross-pieces, co operating with trucks connected with the car-body, and a longitudinal trough or boX supported on the said chord ofthe truss, substantially as and for the purpose described.

4. In an elevated-railway structure, a truss u centrally located with relation to the cars, having its upper member provided with crosspieces, combined with rails supported on said cross-pieces, and longitudinal strips of angleiron having their horizontal portion or flange connected with the under sides ot' said crosspieces and their vertical portion or flange projecting downward from said cross-pieces, substantially as and for the purpose described.

5. In an elevated-railway structure, a truss centrally located below the cars, having its upper member provided,with cross-pieces, and rails supported on the ends of said crosspieces, combined with braces extending downward and inward from the ends ot' said crosspieces to lower chord of the truss, substantially as described.

6. A truss and cross-pieces supported on the chord thereof, provided with upturned ends and rails supported on said cross-pieces and engaged by the upturned ends thereof, and clamps secured to the said cross-pieces between the rails and engaging the lower flanges ofsaid rails, substantially as described.
