PERMANENT WAY FOR ONE-RAIL RAILWAYS. No.175,0Z8. Patented. March 21,1876.





n Specification forming part of Letters Patent No. 175,028, dated March 21, 1876 application `filed November 30, 1875.

.To all whom it may concern Be it known that I, ALBERT G. BUZBY, of Philadelphia, Pennsylvania, have invented an Improved Permanent Way for One-Rail Railways, of which the following is a specification:

My improved track is adapted to cars and locomotives having double-angedbearing or driving wheels adapted to a central rail, and

steadying-whe'els adapted to outer rails; and the object of my invention is to construct an economical and substantial track for cars and locomotives of this class-an object which I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in Which- Figure l is a transverse section; Fig. 2, a

Y. plan view of the track; Fig. 3, a view of one l'orm of bearing-rail; and Figs. 4, 5, 6, and

7, sections illustrating modifications of the track.

In Fgsfl and 2, A and A1 are continuous beams, and constitute the rails, or serve as foundation tor the rails, adapted to the steadying-wheels otl the cars, and D is acentral beam, to which are secured the single rails, adapted to the double-flanged supporting or driving wheels. The three beams are maintained at a proper distance apart from each other by distance or brace pieces a a, and are secured together by bolts b passing through beams and distance-pieces, or by bolts d, ar-

ranged near the distance-pieces and passing If desired, the outer beams A and A1 may be furnished with simple dat bars of iron or light rails, for the steadying-wheels of the 1ocomotive or car.

'When iron has to be used in the' place of wood for constructing my improved track I adopt the plan shown in Fig. 4, in which the track is composed of three H-beams, A2, A3, and A4, secured together and maintained in their proper lateral positions by distancepieces a a', consisting of light castings or of wood. In this case the outer beams may be lighter than the central beam. In place of the H-beams, ordinary railroad-.rails may be secured together in the manner described, the central rail being the heaviest.

Inapplying this plan as a girder for elevated railways or viaducts, I make the central beam or rail much deeper than the outer rails, as shown in Fig. 5,' so that when the whole is properly secured together it will constitute a substantial girder, to which additional strength may be imparted by any suitable system of trussing or truss-rods.

Fig. 6 shows a modification ot' Fig. 5. In this case the outer rails consist ot simple angle-irons, the central rail o't' a deep beam, and distance-pieces of wood or iron, adapted to the rail and beam, and secured in a manner too clearly shown in the drawing to need description.

In either of these plans the central rail may be higher than the side beams.

The modification shown in Fig. 7 consists of four iron beams with distance-pieces, the central distance-piece being made preferably of wood, and serving as a bearing for the central rail of the track.

It will be observed that my improved track is self-contained, the beams and distancepieces constituting a substantial structure, capable ot' ei'ectually withstanding the lateral strains which the central rail receives from the doubletlanged wheels of the locomotive or car.

I claim as my invention- 1.- A one-rail railroad-track, in which .two continuous beams for steadying-rails anda central beam or beams for the bearing-rail arecombined with and secured to transverse distance or Ybrace pieces, all substantially as described.

' 2. The within-described girder for one-rail railroads, the said girder consisting of a deep central beam and two lighter beams or bars,

'combined with distance-pieces, all 'substantally asshown. Y

In testimony whereof I have signed my .name to this speciiication in the presence of two subscribing witnesses. v
