SPECIFICATION forming part of Letters Patent No. 505,478, dated September 26, 1893.

Application filed September 21, 1892. Serial No. 446,474. (No model.) Patented in France December ll 1887, No. 187,583l and in Belgium February 19, 1891. No. 93,823.

To all whom it may concern:

Be it known that I, ESPRIT PERRODY, mechanic, of Geneva, Switzerland, have invented new Improvements in Broad and Narrow Gage Railways, (for which I have obtained Letters Patent in .France for fifteen years, No. 187,583, dated December 1, 1887, and in Belgium, No. 93,823, dated February 19,1891 and I do hereby declare that the following is a full and exact description thereof, reference being made to the accompanying drawings.

This invention relates to improvements in the permanent way of railways, and includes also metal sleepers for roads having two gages.

The metallic sleeper constructed according to this invention possesses the following advantages, viz: it insures an unvarying distance between the rails constituting the road, it gives any desired inclination of the rails, the ballast remaining at the same time per fectly horizontal, it offers a resistance to sliding movement five times as great as that of the wooden sleeper, it renders it absolutely impossible for the bolts to become loose; and thus gives entire safety, it will last for a long time, and finally it oers a surface of support for the line of rails, and for each rail, twice as great as that afforded by the wooden sleeper.

The accompanying drawings illustrate in detail the improvements in question.

Figure 1 is a vertical section showing the end of a metallic sleeper, constructed to carry a rail and a point or switch. Fig. 2 is a vertical transverse section of the end of a sleeper fora single headed rail. Fig. 3 is a transverse section of the end of a sleeper for a doubleheaded rail. Fig. 4 shows in plan a bearing plate serving to connect the single headed rail with the sleeper. Fig. 5 shows in plan the general View of one of my sleepers for a railway with single headed rails. Fig. 6 is an elevation of the sleeper for a railway with double headed rails. Fig. 7 shows the gage or tie-bar of old railway metal which unites the two ends of the sleeper. Figs. 8 and 9 are respectively a transverse and longitudinal section of one end of the sleeper. Fig. 10 is a View in plan of a sleeper for single headed rails laid to form a road with two gages. Fig. 1l is an elevation of a sleeper for double headed rails for a road having two gages. Fig. 12 shows the gage or tie-bar. Figs. 13 and 14 are sections similar to Figs. 8 and 9 but vshowing the ballast in dotted lines.

My metallic sleeper is composed of two cast iron boxes A, A which are filled with concrete to resist crushing strains, and which suplport the rails. .These boxesA, A are connected together by an old rejected rail'B,

which serves as a gage-bar. This bar B enters each of the boxes and its ends are plunged in the Vpacking of cement which nils the boxes; to complete the bedding, the two ends of the bar are pierced with holes C, C into which pass bolts D, D; the heads and nuts of which forming projections are buried in the concrete and i resist removal. These boxes A, Aare of cast iron, steel or any other metal, rolled or cast, on which may be cast any sort of chair for the attachment of any kind of rail R. These boxes are say forty centimeters long and eighteen centimeters wide and deep, and rest on the ballast through the intervention of a wide fiat iron sole A3, about one centimeter thick, sixty centimeters long, and forty centimeters wide, which gives a surface of twenty-four square decimeters, that is to say, a bearing surface of fortyeight square decimeters for each sleeper.

For double headed rails the chair E is cast in one piece with the box on its upper surface at the desired inclination. For single headed rails a bearing surface a which gives the inclination is constructed on the box, which for this purpose is more raised at the outer side than at the inner side of the road. The weight of my sleepers is for single headed rails, say, one hundred and sixty kilograms, disposed as follows, one hundred kilograms of metal and sixty kilograms of concrete. My sleeper for the double headed rail weighs, say thirty kilograms of metal more, on account of the addition of the chair. These weights are at least two thirds less for narrow gage roads of one meter Width; in this case I employ as a gage-bar I-iron of seven or eight kilograms weight per meter. In my system I also make asleeper for the joints of rails, Fig. 14, made up of a sole 1.20 meters long and sixty centimeters wide. This sleeper,

which I call a triple sleeper, has two similar- IOO arrangement is designed to obviate com-l pletely the jolting shock given to each axletree which passes over the joints, which shock is so prejudicial to the rollingstock .and the permanent way and so unpleasant to travelers.

In my system I construct a sleeper (Figs.

10, 11, 12) made up of three boxes A A A2 and of a tie lor gage-bar B traversing the three blocks in one straight line.

stock of lordinary roads to be run over narrow roads, and narrow ygage and "ordinary` gage rolling stock to be included in th-e same train a-t any time when required, .an arrangement which is specially suitable for trains for military purposes.

The bolts F, F, pass through suitable washers which rest lon and confine the rail boxes in their proper positions. The nuts F F of.

said bolts are buried in the cement filling which prevents said nuts from turning and the bolts from loosening downward. l have g devised Ia bolt which could not be loosened` by t-h-e vibrations of the trains and yet could f be easily unfastened when after a certainv By avoidance of these shocks the locomotives are able to draw a load heavier by` This sleeper is designed for an ordinary line and -a narrow. gage line together, thus .allowing .the rolling time it might become necessary to change the rails. However I do not claim herein the construction ot such bolt and accompanying nut.

I claim as new and desire to secure by Letters Patent- 1. A metallic sleeper comprising two iron boxes for supporting the rails, said boxes filled within with concrete, a gage bar extending yinto said boxes and anchored within the bodies of concrete therein, substantially as set forth.

2. A metallic sleeper comprising two iron boxes for supporting the rails said boxes filled within with concrete, a gage bar extending into said boxes, and transverse bolts attached to said bar and embedded in the concrete,

substantially as set forth.

3. A metallic sleeper for-a double gage railroad consisting of three iron boxes for supporting the rails, said boxes lill-ed within with concrete, aigage bar extending into the outer boxes .and through the .intermedi-ate box and lanchored within the bodies of `concrete in said three boxes, substantially as set forth.

4. In a metallic substructure for railroad track-s, the combination of hollow iron supports for the .rails tilledwith concrete, Aproper cross connections betweenl said supports, bolts with nuts for fastening the rails to su-ch supports, such nuts being embedded in the 'concrete, substantially -as set forth.

In witness whereof I have hereunto set my hand .in presence of .two witnesses.
