METALLIC SLEEPER FOR RAILROADS.
SPECIFICATION forming part of Letters Patent No. 404,043, dated May 28, 1889.
Application filedNovember 22,1888. Serial lie-291,538. (No model.) Patented in Belgium December 5, 1885, No. 71,102; in France January 5,1886,1l0.173,396; in England March 16, 1886, No. 3,699, and in Italy July 12, 1886,1I0. 20,243.
To all whom it may concern:
Be it known that I, PIERRE KOLGRAF, a citizen of Germany, residing at Brussels, in Belgium, have invented certain new and useful Improvements in Metallic Sleepers for Railroads, (which have been patented in Belglum December 5, 1885, No. 71,102; in France January 5, 1886, N0.173,396; in England March 16, 1886, No. 3,699, and in Italy July 12, 1886, No. 20,243 and I do hereby declare the follow- 1ng to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
In the accompanying drawings, Figure l is a cross-section of the metallic tie, showing one of the rail-chairs and part of a rail in side elevation.

Fig. 7 is a longitudinal vertical elevation of a tie and its railchairs, the rails being shown in cross-section. Fig. 8 is a plan view of Fig. 7. Fig. 9 is-also an enlarged plan View showing a further modification in the construction of the rail-chair. Fi 10 is a longitudinal elevation showing the arrangement of the tie and its chairs as applied to a macadamized or asphalt road-bed, and FIg. 1.1 is a top plan view of a tie and its rall-chairs of the construction shown in Figs.
7 9 and 10.
The object of this invention is to provide a metallic tie of simple construction and of greater strength than the ordinary U or T sleepers or ties heretofore proposed for railways.
The invention consists, essentially, in the construction of the tie and in the combination therewith of a rail-chair, substantially as hereinafter described, and as set forth in the claims, the essential feature of the invention lying in the cross-sectional form of the tie, and in combination therewith of a chair for the rails, acting as a brace for the tie.
Referring to the drawings, T indicates the tie, that is composed of two sections or bars of iron or steel having the form or substantially the form of a letter, Z, in cross section that is to say, the sections are formed of a Web, t from the upper and lower ends of which project flanges t and t in reverse directions, the flange t serving as a bed or bearing plate, while the flange It serves as a bedding-plate, to be embedded in the ballast of a track or the paving material of a roadway. The two bars or girders are or may be con nected together by means of bolts simply, and the rails may be secured thereto in any desired manner, the connection being so arranged as to hold the two bars at a proper distance from each other to form a good bearing for the rails on the upper flange, i.
In practice I prefer to provide a separate bearing or chair C, for the rails, which also serves to connect the two sections of the tie firmly together.
In Figs. 1 to 3 I have shown this chair as constructed with open lateralsides 0, open top a, and open bottom 0 the solid front and rear walls, 0 being connected by a transverse web, 0 Fig. 1, and with inwardly-projecting lugs or horns 0 for the foot of the rails,which seat upon the upper edge of the front and rear Walls, 0 The chair 0 is bolted to and between the tie-sections by means of bolts i as shown, thus providing not only a proper support for the rail R, but also a very strong connection for the two sections of the tie T. \Vhere the tie is employed in an ordinary ballasted or a macadamized road-bed and it is desired that the tread of the rails should be flush with said road-bed, I employ an auX- iliary rail, R, Figs. 2 and 4, that is bent outwardly, as shown at r, the web o of such rail bearing against the web of the main rail R and resting upon the foot 7" of such rail, as more plainly shown in Fig. 4. This rail B may be bolted to the rail R, if desired; but it has been found in practice that the usual con nection-such as the fish-plate connection of two sections of main and auxiliary rails-is sufficient to securely hold the auxiliary railsections in position, said rails being further supported by the ballast or other paving material of the road-bed in which they are embedded.
In road-beds constructed of concrete the I auxiliary rail may be dispensed with, as shown in Fig. 10, a gutter being formed along the inside of the rails R for the flange of the carwheels to run in. The chair shown in Figs. 4 and 5 has a vertical transverse web, 0 as shown in dotted lines in said Fig. 4. In Figs. 6 to 8 the lateral sides of the chair are somewhat modified in construction, said sides having an opening formed in them, instead of being entirely open, and the projecting lugs or horns being made broader to provide a greater locking-surface, while the chair shown in Figs. 9 to 11 has its four sides solid and its top and bottom open,the front and rear walls being connected or braced by a vertical transverse web, 0.
The rails B may be secured to the chairs 0 in any convenient manneras, for instance, by means of a split key, K, as shown.
By means of the described construction the ties T may be so embedded in the roadway or track as to leave the rails or the tread of the rails above the same; or the said ties may be so embedded in the roadway or track as to leave the tread of the rails R flush therewith,
thus doing away with the objectionable feature of projections above the road-bed.
The construction of the tie is also such as to offer a greater resistance to pressure or strain either vertically or laterally than the ordinary T or U ties, and also provides greater bearing-surfaces, as will be readily seen at a glance of Fig. 1.
Having described my invention, what I claim is- 1. A metallic railway-tie, T, consisting of two bars composed of alvertical web, and flanges t t, projecting at right angles thereto inopposite directions, and a chair, 0, interposed between said bars and bolted to the vertical web thereof, said chair being provided with lugs or horns c for the reception of the rail-foot, substantially as and for the purposes specified. 7
2. A metallic railway-tie, T, consisting of two bars composed of a vertical web, and
flanges t t, projecting at right angles thereto in opposite directions, and a chair, 0, interposed between said bars and bolted to the web thereof, said chair having open sides and top, a web, 0 connecting the front and rear walls, and lugs or horns c, for the rail-foot, substantially as and for the purposes specified. In testimony whereof I affix my signature in presence of two witnesses. I
