UNiED STATES GEORGE ALBERT PENROSE, THOMAS FLORISTON PENROSE, AND VILLlA-M R. WARE, OF MEREDITH, ARKANSAS.

METALLIC RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 617,600, dated .Tammy 10, 1899.

Application led-J une 29, 1898.

To all whom t may concern.-

Be it known that we, GEORGE ALBERT PEN- ROSE, THOMAS FLoRIsToN PENROsE, and WIL- LIAM R. WARE, of Meredith, in the county of Woodruff and State of Arkansas, have invented a new and Improved Metallic Railroad- Tie, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved metallic railroad-tie which is simple and durable in construction cheap to manufacture, and arranged to hold the raill securely in place without the use of spikes, and to fasten the ends of adjacent rails together without the use of'iish-plates and like devices. Y

The invention consists of novel features i and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figurel is a perspective view'of the improvement as applied. Fig. 2 is a perspective view of one of the sections of the tie.

Fig. 3 is a plan view of part of the improvement with the rails inV section. Fig. 4 is a transverse section of the improvement on the line 4 A of Fig. 1, and Fig. 5 is asimilar view r of the same on the line 5 5 of Fig. l.

The improved railroad-tie is made in two longitudinal sections A A', iitted upon one another by suitable tongues and grooves, so as to render the sections interlocking, said sections being made hollow at their inner faces to render the tie as light as possible. The sections A A are fastened together by transverse bolts B, as is plainly shown in the drawings, it being understood that longitudinal movement of the sections is prevented by the interlocking tongues and grooves. The bases of the rails C rest on the top surfaces of the sections A A', and said rails are secured in place on the sections by sets of lugs D D on the section A and lugs D2 D3 on the section A. The lugs D and D2 are arranged in such a manner as to engage opposite sides of one rail, and the lugs D and D3 are similarly lo- Serial No. 684,733. (No inodel.)

As shown in the drawings, the lugs D2 extend over the corresponding base portion of the rail and up along the web and al portion of the under side of the head of the rail to prevent lateral as Well as longitudinal shifting of the rail when the two sections A and A are interlocked and fastened together bythe bolts B. v

In making the railroad-track the sections A are first placed in position, the sections A' being disconnected therefrom and slightly drawn apart to permit of placing th'e rails C on the top surface of the sections between the corresponding sets of lugs D D2 and D D3. The sections A' are now shifted longitudinally to bring the sets of lugs in close contact with the Opposite sides of the rails, and as the interlocking tongues and grooves are now in register with each other the two sections are moved transversely together, so as to interlock the same and to permit of inserting the bolts B through the now registering apertures in the sections A and A.

The railroad-ties on which the ends of adjacent rails C rest have their lugs D D and D2 D3 formed with extensions D4, and the lugs and extensions are apertured to permit of inserting bolts E through the said lugs and extensions and through apertures in the webs of the rail ends. Thus, as shown at the left in Fig. l, the extension D4 ofthe lug D2 is brought opposite the lug D, and the bolt E passes through the said extension, the rail, web, and the lug D,while theextension of the latter is opposite the lug D2, and the bolt E passes through the extension Of the lug D and the lug D2. A similar arrangement is illustrated at the right in Fig. 1, in which the extension for the lug D3 is opposite the lugv D and the bolt connects the three parts, while the extension of the lug D is opposite the lug D3 and the plate engages the said extensionlug and the web of the rail.

arrangement described the lugs D D' and D2 D3, with the extensions, securely -hold the rails in place, so that spikes or like fastening devices are not required, and where the ends of the adjacent rails engage the tie no fish- Thus by the 95 IOO plates are required for fastening the ends together, as the construction of the lugs, with the bolts and extensions, forms a fastening device for uniting the ends of the rails and at the saine time holds the rails down in position on the tie.

The hollow sections are preferably provided on the inside with longitudinally-extending ribs A2 and transverse ribs A3, preferably made to interlock at their ends to strengthen the sections and to assist in the interlocking, as previously explained.

The under side of the tie-sections A A is preferably concaved, as shown in Fig. 5, to permit of securely holding the tie in place on dirt-ballast railroad-beds.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. A railroad-tie made in longitudinal sec tions each formed with a pair of lugs arranged in such a manner as to engage opposite sides of the rails, the lugs extending over the corresponding base, Web and under side of the head of the rail, and each lug being provided with an extension, and bolts passing through the lugs, extensions and Webs of the rails, substantially as shown and described.

2. A metallic railroad-tie made in longitudinal hollow sections adapted to be fastened together, and each formed with longitudinal and transverse internal strengthening-ribs, 1

substantially as shown and described.
