M ETALL IC RAl LROAD-Tl E V SPECIFICATION forming part of Letters Patent No. 351,498, dated October 26, 1886.

Application filed April 13, 1586. Serial No. 198,709. (No model.)

ful Improvementin Metallic Railroad-Ties, of

which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification,

v in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved tie, showing parts of two rails secured to it, the ends of the tie being broken away. Fig. 2 is a side elevation of a part of the same, and part being shown in section through the broken line 00 m, Fig. 1. vation of the same, takent-hrough the line yy, Fig. 2,"and showing a part of a rail in side elevation. Fig. 4 is a sectional side elevation of one of the rail-holding blocks.

The object of this invention is to provide metallic railroad-ties constructed in such a manner as to hold the rails securely from spreading, and which shall be simple in construction and strong and durable in use.

The invention consists in the constructionand combination of the various parts of the tie, as will be hereinafter fully described.

A are two parallel bars, whichmay be pieces of old railroad-rails or bars rolled expressly for this use. In the latter case the adjacent sides of the heads of the bars A can be omit ted, so as to form between the said bars a Fig. 3 is a sectional en'd ele-' .formed a hookprojection, O, of such a shape as to overlap and fit snugly upon the baseflange of a railroad-rail, D, as shown in Fig. 5 2. Four of the blocks B are used on each tie, two for each rail, and which are so arranged that the projections of each pair of blocks will engage with the opposite flanges of a rail. The blocks B are secured in place in the ties by bolts E passing through them and through the bars A. Two of the blocks B viz., the outer blockat one end and the inner block at the other endare secured in place in the bars B at the shop where the ties are made.

The other blocks B are left loose. In setting the ties the said ties are placed upon the ground and the rails are arranged in place. The ties are then moved longitudinally to bring the hook projections of the permanent blocks into place upon the flanges of the rails. The other blocks are then moved into place, and'are secured by the boltsE. \Vith this construction the rails will be held securely in place, and the spreading of the rails will be 6 prevented.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent A metallic railroad-tie constructed substan- 7o tially as herein shown and described, and consisting of two parallel bars, A, having a channel between them, the blocks B, fitted into the said channel and provided with hook projections 0, to fit upon the base=fianges of the rails, 7 5

and the bolts E, securing the said blocks to the said bars, whereby railroad-rails can be readily secured to the said ties and will be held securely in place, as set forth.
