RAILROAD-TIE.

H z SPECIFICATION forming part of Letters Patent No. 579,520, dated March 23, 1897.

I Application filed $eptember 26, 1896. Serial No. 607,077. (No model.)

.To alt whom it may concern.-

Be itknownthat'I, ROBERT PIMCRAE, a

citizen of the United States, residing at St. Albans, ,in the county of Kanawha and State of West Virginia, have invented certain new "and useful Improvements in 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.

. My invention relates to railroad-ties, the object of the same being to provide a metal: lic cross-tie for railroads which is cheap in construction and more durable than the ordinary wooden tie now commonly employed.

The invention consists of a metallic crosstie, -T {shaped'incross-section, the upper flanges thereofbeing braced and supported at points just beneath the securing-points .of the rails to prevent longitudinal displacement of the tie or a bending of said flanges. On the top surface of the tie, a short distance from each end thereof, suitable rail-securin g means are provided.

The invention also consists in other details of construction and combinations of parts, which will be hereinafter more fully described and claimed.

In the drawings forming part of this specification, Figure 1 represents a perspective view of a tie constructed according to my invention with rails shown secured thereon. Fig. 2 is a vertical longitudinal section. Fig. 3 is a cross-section on the line so or of Fig. 2. Fig. 4 is a detail perspective of one of the rail-securing devices with the track-rail removed. Fig. 5 is a bottom plan view of the tie with bracing-plates thereon.

Like numerals of reference indicate like parts in the different views.

My improved tie 1 is constructed of metal,

T-shaped in cross-section, with the upper flanges 2 2 thereof suitably braced or supported by the plates 3 3, riveted, bolted, or otherwise secured to the upright portion l of said tie and to each other. Said plates 3 3 are located at points just beneath the rails 5, and serve the function of preventing the bending of the flanges 2 and the longitudinal displacement of the tie 1. The said plates are L- shaped in cross-section and are bolted, riveted, or otherwise secured to each other and to the upright portion at of the tie.

On the upper surface of the flanges 2 2, at

points adjacent to the outer ends of the tie, are rail-securing devices 6 6, the same being arranged in pairs, as clearly shown, and bolted or otherwise secured to the top surface of the tie 1. The same consist of blocks 7 7, formed with solid bases 8 and with inwardly-extending flanges 9 9, the same being cut away, as shown at 10, to permit the passage of the base of the rails 5 therein, and the members of the pairs are so located relatively to one another that the web of the rail is clamped on both sides. By this construction it will be seen that the rails 5 are adapted to be inserted into place Without the employment of spikes,

and that when once in place they are heldeach other, whereby longitudinal displace ment of the tie and bending of the upper flanges are prevented.

2. A metallic railroad-tie,T-shaped in crosssection, and bracing or supporting plates L- shaped in cross-section, bolted, riveted or otherwise secured to one another and to the upright portion of said tie, whereby longitudinal displacement of the tie and a bending of the upper flanges are prevented.

8. A metallic railroad-tie,T-shaped in crosssection, having rail-securing devices secured to the upper surface thereof adjacent to its outer ends, the said rail-securing devices consisting ofblocks arranged in pairs having inwardly-projecting flanges thereon and cutaway portions at theirlower ends between which the bases and webs of the rails are adapted to fit, and bracing or supporting plates secured to the upright portion of said tie and to each other just beneath the said railsecuring devices, for preventing longitudinal displacement of the tie and a bending of said flanges, substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ROBERT P. MORAE.
