CHARLES DELORMEND EMILE BROCl-ION, OF TROYES, FRANCE.

, METAL RAILWAY-SLEEPER.

SPECIFICATION forming part of Letters Patent No. 429,607, dated June 10, 1890.

Application led December 2, 1889. Serial l.\Tc|.332,290. (No model.)

To all whom it may concern:

Be it known that we,CHAELEs DELORME and EMILE BROCI-ION, citizens of the Republic of France, and residents of Troyes,France, have invented certain new and useful Iniprovementsin or Relating to Metal Railway- Sleepers, of which the following is a specifi-V cation.

The improved metal sleeper constituting the object of this invention is represented in the drawings accompanying this specification, in which drawings- Figure 1 is an elevation, and Fig. 2 aplan, of the sleeper with portions of rails attached. Fig. 3 is a transverse section on the line AB of Fig. l. Fig. 4 is another sectional view on the line C D of Fig. 1. Figs. 5 and 6 are perspective detail views of parts of the sleeper.

, On examining the iigures it can be seen that the metal sleeper consists of two distinct parts, the body E and the base F; The body E is of iron or steel of 1-shaped or channeled section, the upper surface of which forms the bed or seat of the rails, while the vertical webs form the sides of the sleeper. The base F is also constructed of, preferably, rolled iron or steel, and is formed with two longitudinal parallel grooves G G', into which fit the lower edges of the two vertical webs o the body E of the sleeper.

Beyond the grooves G G at each side of the sleeper, extends the base F, so as to form two longitudinal edges, which support the weight of the rails, whereby the sleeper, when once iixed in position, will be solidly bedded and held in a vertical position.

It can be easily understood that by the webs of the body E being retained in the grooves G G of the base F the rigidity of the body is considerably increased. The webs of the body E, by being so retained in the grooves G G, cannot become spread apart or closed toward each other, while at the same time the sleeper retains sufficient elasticity.

Among the many forms of sleepers hitherto devised are some which are madewith a view to economy; but these have been deficient in rigidity, and those which possessed sufficient resistance were of no practical value, because, owing to their complicated nature and great weight, they were too costly.

The simplicity of construction combined with the lightness of our sleepers lessens their cost to an extent not hitherto attained.

The body E of the sleeper is attached to the base F by means of rivets or bolts l-I, which serve at the saine time to hold the clips or chairs of the rail. So constructed our sleeper is of great strength; but taking intoaccount the transverse strains which are to be met more particularly at the curves of the track by the bolts or rivets joining the two parts of the sleeper, the body E and base Fv act to diminish that strain, and thereby afford greater security. To attain this object, we make the base F longer on bot-h sides thanrthe body E,

as is shown in Figs. l, 2, 3, 4, and G, and we.

divide by two longitudinal cuts the said proj ectin g portion. The two symmetric parts R include the grooves G G', andthe part S is between the two parts R. The two parts R are thrned up to a right angle against the ends of the wings of the body E, which 'fitup to a certain point of their height into the upturned parts of the grooves G G. In the same way the rivets or bolts H, and also the base F, assist with the ends R raised against the body F. to hold the latter transversely,whereby the bolts or rivets H are to a corresponding extent relieved. The part S is bent downward to a right angle to the base in such a way as to enter the ballast, and thus afford all the required anchorage to secure the sleeper in position. The edges ot' the raised parts R on both sides of the grooves G G also contribute to retain the sleeper in position, as these parts are also bedded in the ballast.

Our sleeper can beused for supporting rails of any section.

At X in Figs. l, 2, and 3 we represent, as an example, a iiange-railheld upon our sleeper by means of the chair-clips or jaws I, of iron, steel, or any other suitable metal. -This chair is fixed upon the upper surface of the sleeper by means of the same rivets or bolts I-l as serve to join together the bodyE and base F of the sleeper. The flange M of the rail is placed in the chair I, and is held there by a key L, which may be provided with a hole N, into which a pin may be placed for the objectof preventing any displacement of the key L.

As it is sometimes necessary to maintain the rail upon the sleeper by means of clamps, spikes, or screws, as is shown with the rail Y IOC in Figs. l and 2, we place into the empty space in the interior of the sleeper, at its ends, a block P of Wood, which we fix in position by the rivets or bolts H, employed to hold together the two parts of the sleeper, and we form holesQ in the upper surface of the body E, so as to leave a passage for the woodscrews or clamps, which serve to attach the rail to the sleeper. These wood-screws, spikes, or clamps fit solidly into the wood P and maintain in position the rail as perfectly and satisfactorily as if Wooden sleepers Were used.

It is evident that the Vdimensions and the metal of which these sleepers consist can be varied according to requirements, and also dii'erently-shaped rails could be lixed upon our sleepers, and also that there may be used any kind of chairs or clips other than those before described for securing flanged rails in position.

Ye claiml. In a railway-sleeper, the combination, with the channel-shaped body having the downwardly-turned sides extending' from end to end, of the substantially fiat extended base having the longitudinal grooves for the downwardly-extending sides of the body exi-ending from end to end of the ties, whereby distortion is prevented, substantially as described.

2. In a railway-sleeper, a base, such as F, longer than the body E, the parts projecting beyond the ends of the body being divided into three parts R R S, the first two, including the prolongation of the grooves Gr G', being turned up toward the ends of the webs of the body E,which webs fit into the grooves G G of the said base, while the third part Sis bent downward to a right angle to the base, in order to iit into the ballast, substantially as herein specified, and illustrated in the accompanying drawings.

3. In a railway-sleeper, the combination, with the body having the downwardly-turned sides, of the base having the independent grooves for said sides and the extended ends bent upward and forming stops against which the ends of the body abut, substantially as described.

4. In a railway-sleeper, the combination, with the channel-body and independent base, of an internal wooden block, a chair 'for holding the rail in position, and the boltor rivet passing through the chair, body, block, and base, whereby all the parts are held rigidly in position, substantially as described.

5. In a'railway-sleeper, the combination, with the channel-body and independent base, of a wooden block fitted in said channel and between the body and base, and a bolt or `rivet passing through the body, block, and

base for holding the parts rigidly in position, substantially as described.

In testimony that We elailn the foregoing as our invention We have signed our naines, in presence of two witnesses, this 14th day of November, 1889.
