SPECIFICATION forming part of Letters Patent NO. 756,317, dated April 12, 1904.

Application filed July 6,1903. Serial No. 164,272. llo model.)

To all inlwm it may concern.-

Be it known that we, LOUIS Batman and MICHAEL J. Bunznn. citizens of the United States, residing at Pittsbur in the county of f 5 Allegheny and State of Pennsylvania, have inments in Railway Construction, of which the following is a specification.

In the accompanying drawings, which make part of this specificatiomFigure 1 is aplan view of our invention, a central portion being removed. Fig. 2 is a cross-section of the tie, taken on the line 2 2 of Fig. 1. Fig. 3 is a longitudinal section taken on the line 3 3 of Fig. 1.

Our invention relates to railway appliances and more particularly to railway-ties and railfastening devices.

It is the object of our invention to provide a substitute for the common wooden ties, which, owing to the growing scarcity of suitable wood and their increasing cost, must give \vaytoasuperiorand permanent article. We have devised atie which is not only cheaper by eifecting a great saving in maintenance, but one which, with its rail connections, is practioallv indestructible. Our tie bein thoroughly waterproofed will not be afl'ec by frost, and the parts are so strongly united 30 that they will not become broken or separated. Vl-"e also give the rails a suitable elastic bed, which not only makes the train less noisy and less injurious to the rolling-stock, but also prevents to a large degree the pounding action of the ear-wheels from being transmitted so suddenlyto the concrete portion of the ties, the resultbeing that the ties will not be cracked or broken.

Referring to the drawings, Arepresents the tie as a whole. having beveled sides and ends, as shown in Figs. 1 and 2. which retain the tie more securely to the ballast. The corners of the tie are rounded, since angular corners are liable to be broken in ballasting. The bodies of the ties are made of s] -cement concrete or other lastic material w ich will set or become her and each tie has embedded therein when formed a steel channel-plate B, having the bottom b and the downwardly- 5 extending sides or flanges b. The plate has ventedordiscovered new and useful Improve- 3 D ,usual manner.

numerous holcs 1/, which allow the conrrrto to pass through, so as to'iic or bind the tie into a more solid and more hcnnuinrnronsnines than would be thc case if the ronrrvto were unconnected along the vnllrr surface of an 'llw plnto ll extends nearly the whole length of thc tic.

Beneath each rail and rcstin on the tirnro layers F of compressed cork or wood libor covered by steel cap-plates (l, having! llnngrd edges bent so as to protect the mines of the layers F.

The layers F may be seated in recesses in the concrete, if desired, to provrni the edges of the ln 'ers from squeezing out beneath the cap-plates (i.

The rails E lie directly on the plates (l and are secured thereon by spikes ll, whose brads h engage the tops of the rail-flanges in the The spikes are driven down in lead or other soft-metal sockets J, having hcndsfcngnging the under side of the bottom I: of the plate B to prevent their withdrawal. The lead sockets have one or more bends j on their outside. As the concrete lits closely to the whole external surface of the sockets, the

letter will by means of the beads be held securely in the concrete.

The sockets have longitudinal openings of a size to make a very tight lit with thespikes when the are driven in. The lead Will flow so as to pack tightly about the spikes and to stick tenaciously to the same.

The concrete we prefer to use is made of slag and cement; but we do not desire to be limited to this composition, as other plastic hardening compositions may be used.

Having described our invention, wc claim 1. In railway construction, a plastic matc- -ial,soft-nictal sockets therein, rails, and spikes driven into the said sockets to secure the rails to the plastic material.

9.. In railway construction, a plastic matcria-l, sofmnetnl sockets therein having exterior bends interlocking with the plast c material. and means in said sockets and in engagement with the rails to hold the latter in place on the plastic material. I

3. In railway construction, a plastic material, p nn tnl plate embedded therein, a soft '9 706,617 l1 metal socket having means engaging said plate to prereut its movement, and spikes in the sockets and in engagement with the rails to held the latter in place on the plastic material.

$1. In raihva construction, a plastic materiaL compressed elastic wood on said material, metal cap-plates on said wood, rails on the cap-plates soft-metal sockets in the plastic material and spikes in the sockets and in en gagemrnt with the rails to hold the latter in place on the cap-plates.
