SPECIFICATION forming part of Letters Patent No. 602,888, dated April 12, 1898.

Application filed May ll, 1897.

To aZZ whom it may conccrn: I

Be it known that I, JOHN ALEXANDER SOHMAHL, of Fairman, in the county of Marion and State of Illinois, have invented certain new and useful Improvements in Metallic Railroad-Ties; and I do 'hereby declare the following 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.

The object of this invention is to provide a metallic railroad-tie which will be comparatively light and the parts so disposed and braced as to present a strong and durable structure that will properly support the rails to withstand the jars which come upon the same in use. To this end the railroad-tie is made up, preferably, of galvanized iron bent to form bottom and side pieces, the edges of the latter being recessed to receive the rails, which are held in place by retaining plates or clamps and rest upon chairs which are bolted to the side pieces of the tie, a crosspiece being secured to the under side or bottom of the tie to assist in making a secure engagement with the road-bed.

Having the above objects in view, the inven tion consists in a metallic railroad-tie having upwardly-projecting side fianges at right angles to and integral with the bottom of the tie and which are recessed to receive the rails, retaining plates or clamps for holding the rails in engagement with the tie, means for bracing and preventing spreading and collapsing of the side fianges of the tie to each other, and a cross-piece which engages the road-bed to prevent movement of the tie.

In the following' specification I have entered into a detailed description of the different parts which constitute my invention, reference being had to the accompanying drawings and to letters 01' num erals thereon,which designate the difierent parts, and what I consider to be the novel features of construction are specifically set forth in the claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of a railroad-tie constructed in accordance with my invention. Fig. 2 is a tie from one'side piece to the other.

side elevation. Fig. 3, is a longitudinal sectional view, and Fig. 4 is a transverse sec- ,tonal view.

vReferring to the drawings by numerals and letters, 1 designates the bottorn of the railroadtie, fromV which the side pieces 2 2 exten'd upward at the edges thereof, presenting a metallic tie whichis practically U -shaped in crosssection. The metal of which the tie is made is preferably galvanized iron, as it possesses certain qualities which will add to the strength and durability of the tie. The side pieces 2 2 are provided with recesses 3 that receive the rails, and below said recesses, preferabl5T on theinner sides, are bolted angle-iron chairs 4, presenting a cross-piece upon which the rails rest, the said chair having dependin g end flanges through which the retaining-bolts pass. In order to hold the rails in positive engagement with the tie, I provide certain retaining plates or clamps, which consist of the plates 5 5, having bevel ends a, which overlie the baSe-fianges of the rail and bear thereon, the said plates being held securely in position by transverse bolts 6 6, which extend across the It will be observed that each side piece of the tie is provided with plates at opposite sides of the recesses therein which receive the rail, and the said plates are securely held by the bolts, which pass through the same near their opposite ends. i Upon the bolts 6 6,which secure the retaining-plates in place, are mounted tubes 7 of a length to bear between the re- ,taining-plates at opposite sides of the tie, said tubes forming'braces which prevent the side pieces from bending inward, the heads of the bolts and nuts on the opposite ends preventing a spreading movement of the side pieces with respect to each other.

In connection with a railroad-tie constructed as hereinbefore described I provide the same with a cross-piece 8, which is attached 'to the under side of the said tie at the central portion thereof and engages the road-bed to prevent movement of the tie thereon.

By forming the railroad-tie of galvanized iron it is not affeoted by rust, and will consequently be very durable, and, if desired, the

part thereof between the side pieces could be filled With rubble or composition to assist in holding it in place.

From the foregoing description, in connection With the accompanying drawings, it will be apparent that I provide a metallic railroad-tie which Will be cheap in construction and thoronghly braced to Withstand the pressure or Weight that will come upon the same, the devices or clamps for holding the rail in en gagement With the tie preventing any possibility of the rail spreading, while also bracing the side pieces of the tie.

The tubes 7 on the tie-bolts 6 afiord a means for clamping and holding the side plates absolutely in fiXecl relation to each other to pre- Vent rattling.

I-Iaving thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-- A railWay-tie formed of sheet metal With recessed, Vertical, parallel side flanges integral With the bottoln, in combination with through-bolts connect-img said side fianges, sleeves 011 said bolts intermediate said fianges, parallel rail-clamping bars on the throughbolts at the opposite ends of the sleeves and on opposite sides of the rail, intermediate the ends of the sleeves and the side flanges of the tie, and clainped by said sleeves and through-bolts against the side flanges of the tie, and angle-iron chairs having pendent, Vertical end fianges secnred to the sides of the tie, said chairs extending from one side to the other under the recesses in the side flanges in the tie, substantially as described.

In testiinony Whereof I have signed this specification in the prcsence of two Subscribing Witnesses.

JOHN ALEXANDER SCIIMAIIL.
