RAILWAY- RAI L PAD.

' SPECIFICATION forming part of Leners Patent No. 382,803, eared May 1s, 188s,

Application filed December 15, 1887. Serial No. 257,945. (No model.)v

To all whom it may concern:

Be it known that we,l HART J. FACKEN- THALL and LEwIs WALLACE,'both\of Philaand Improved Railway-Rail Pad, of which the following is a full, clear, and exact descrip.- tion.

Our invention relates to an improvement in railway-rail pads, and has for its object ,to provide a means whereby the noise incident to the passage of a train over the rails will be avoided, and wherein the life of a rail will be lengthened, likewise that of the rolling-stock, and wherein the wear and tear upon bridges and trestle-work will be reduced to a minimum.

The invention consists in the novel construction of an elastic pad for railwayrails, and in the combination of the'pad with the rails, as will be hereinafter fully set forth, and pointed out in theclaims.

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

Figure l is a perspective view of the pad, and Fig. 2 is a transverse section through a rail and a pad applied thereto.

It is the prime object of this invention to provide a means whereby the rails of a railgitudinal edges, a, of the block in its normal condition are beveled, and that portion of the block intervening the aforesaid beveled edges is concaved in Cross-section vupon the upper face, which concavity extends from end to end,

as shown at b in Fig. 1. Centrally and longi- A tudinally the concaved face b of the block a rectangular rib, D, is produced integral with the body, the sides d and ends d of which rib are preferably inclined from the body upward,

the surface of the rib being concave, as ,illus,A

trated at d2. The highest points of the rib D are in alignment with the outer longitudinal edges of the block, an'd the said rib is preferably made of shorter length than the body,

as shown in Fig. 1. We do not, however,

confine ourselves to the aforesaid dimensions,

as the'rib may extend from end to end, being made short only for economy of material. The base E of the block is perfectly fiat.

In operation a pad or block is placed transversely the ties C and the rail longitudinally thereon.

`flat. It isevident that the block also augments the clinging of the rail to the tie, as by means of the suction attendant upon the use y When the said rail is spiked down ,n to the tie,the upper longitudinal edges of the block are widened and the surface of the-rib When the spikes become of vthe rubber block thesaid block clings fast to the tie and likewise to the rail.

yHaving thus described our invention, ywhat We claim as new, and desire to secure by Letters Patent, is

1. The combination, with a railroad-rail and its t`1`e,of an intervening elastic pad provided with al flat" under face, aconcave upper face, and a central longitudinal rib, as and for the purpose herein set forth.

2. The combination, with arailroad-railand its tie, of an intervening elastic pad provided with a flat under face, a concave Vupper face, beveled longitudinal edges, and a central longitudinal rib having a concave face, the side edges whereof are of a height equal to the side edges of the body, substantially as shown and described.

3. As an improved article of manufacture, an elastic pad for railway-rails, consisting of a block provided with a flat under surface, beveled upper longitudinal edges, a concave upper face, and a central longitudinal rib having a concave upper face the side edges whereof are equal in height to the side edges of the block proper, substantially as and for the pur- 1o pose herein set forth.
