RAILROAD-TIE.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed February 14, 1905. SerialNo. 245,572.

To all whom it may concern;

Be it known that I, JOHN G. SNYDER, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification.

My invention relates to improvements in railroad-ties, and one object is the provision of a railroad-tie which will be very durable or have a very long life, rendering the tie more desirable and economical, all matters considered, than the ties in general use.

Another object of my invention is the provision of a railroad-tie which will form a perfect support for the rails, allowing for the necessary expansion and contraction and which will provide a perfect cushion and noisedeadener for the rails, thus insuring a railroad-tie combining every requisite to render the tie thoroughly practical and efiicient in every particular.

To attain the desired object, my invention consists of a railroad-tie embodying novel features of construction and combination of parts, substantially as disclosed herein.

Figure 1 represents a vertical longitudinal sectional view of one end of my railroad-tie. Fig. 2 represents a plan view with one of the connecting and fastening plates removed; and Fig. 3 represents a plan view of several ends of the ties with a rail in position or, in other words, a plan view of the complete improvement.

In the drawings the letter A designates the hollow casing or jacket or shell of my tie, which is preferably made of metal, and particularly of steel, and this casing is formed near each end with the recesses B, which are formed by the vertical walls C, said walls being formed at their upper edges with shoulders D, in which are adapted to fit the securing-plates E, as will more fully appear.

The casing or shell is entirely filled with a substance, such as concrete or other suitable material F, which will form a perfect solid mass whichrests upon the ground, and this construction provides the bed or support G, upon which rests the recessed chair H, in the recess or seat or socket J in which are placed e lower zinc or deadening plate K and the intermediate lead plate K and the steel or the upper rail-supporting plate L, upon which rests the foot M of the rail, and the connecting-plates or securing-plates E are retained in 'place upon the chair and the walls of the tie by means of the vertical fastening-bolts N, the under side of the chair having kerfs N to secure the fastening-bolts from turning, and the plate E is provided with slots O, which permit the sliding of the plate into position upon the foot of the rail.

From the foregoing description, taken in connection with the drawings, it is evident that I provide a railroad-tie which although initially will cost more than the ordinary Wood tie will last for so long a time as to make it really cheaper than the ordinary tie; also, that the tie forms a perfect support for the rail and gives a cushion toinsure smooth and even riding and deadens all sound, and also that it can be easily transported and assembled and that its use will fill a long-felt want in a perfect manner.

If desired, I may also place a lead plate under the plates that clamp the rail to the ties, and I have found by experience that the best results are obtained by usinga one-inch steel plate, a half-inch lead plate, and ahalf-inch zinc plate; but these proportions may be changed.

I claim- 1. A railroad-tie consisting of a casing or shell having recesses or chambers near each end, a filling or mass of material in said casing forming a support and a bed under each chamber, a chair fitting in each chamber upon the said bed, and rails mounted and supported upon said chairs.

2. A railroad-tie consisting of a casing or shell having recesses or chambers, a filling or mass in said casing forming a bed for said chambers, chairs resting upon said bed and formed with recesses, a deadening-plate, an intermediate plate and a rail-supporting plate arranged in the recess of the chair,rails mounted on the rail-supporting plates and means for securing the rails in position.

3. A railroad-tie consisting of a metal casing or shell and a filling of suitable material,

metal chairs resting upon the filling, deadenengaging the foot of the rail and mounted ing' and supporting plates seated in said chairs upon the chair and easing. 1 and a rail on the supporting-plate.
