To all 'whom it 'may concern.; A Be it known that' l, HENRY H. CLOUGH, a citizen of the United States, and a sident of Elyria, in the county of Lorain 'and State of Ohio, have invented certain new and useful Improvements in Concrete Railway-Ties, of which the -following is a specification.

In the use of railwayties made of cement concrete, one difficulty experienced has been the tendency of the concrete to break or crack beneath the rail under the sudden blow caused by the rapid assao'e of heavy rolling stockalong the tracliifand While the stiem ing irons which are ordinarily embedded in concrete ties 'tend to` prevent'their being cracked and broken inthis manner, it is impracticable to wholly obviate the difficulty y means ot' such stiening irons without lusing an amount of iron which renders the 20 tie too heavy and too expensive for practical use.I f-

The object' of the present invention is to provide an improved vconstruction 1nconcrete vlrailway ties by which this liability of the concrete to break or crack under the sudden shock of the passing locomotive or train 1s`l overcome Wlthout unduly lncreasmgthe weight and expense of the tie,.and to this end the invention consists'in the matters herein set forth and particularl pointed out in the appended claims and wil be fully understood from the following description of the construction illustrated in the Aaccompanying drawings, in whichh Figure 1 is a top plan view of a concrete tie constructed in accordance with my invention.v Fig. 2y is a side elevation of a portion of said tie, showing the track rail in section. Fig. 3 is a transverse sectional detail taken on line 3 3 of Fig. 1. Fig. 4 is a perspective view of one of the metallic jackets which yis used to inclose that portion of the tie at each l end upon which the track is laid.

Ili'said drawings, 1 designates the body of a tie and 2 any suitable stiiening irons, such as twisted iron bars, embedded 1n the body of the concrete so as 'to' stiffen it.

3 are metallic strengthening casings or jackets which embrace the tie near itsends v and at points beneath the track rails 4, when' the latter are in place. These bands or jackets may conveniently be formed of malleable cast iron, and consist of a base plate or web 5 which extends across the bottom of the tie, and ofside plates or Webs 6 which are made integral with the bottom plate 5 and extend upwardly along the sides of the concrete tie body, vertical ribs 7 being provided on the outer faces of the side plates 6 to strengthen the latter and increase the length of base P'su port'oiered to the ra'il4.

nthe approvedconstruction shown, also,

each such casing or jacket is provided with a top web or plate 8 cast integral with the rest of the casing and forming a chair for the rail to rest upon. i This top plate is shown as projecting beyond the side plates 6 at each of its ends 9 so as toform an extended seat or bearing for the rail, and such projecting ends 9 are shownV as su ported centrally by said yribs 7 ofthe side-p ates 6. 'l-he sides of the top plates 8 are furthermore shown as widened at the opposite corners and aspro` vided with apertures 10 through which any suitable fastening devices 11 may be passed to secure the rail to the tie.'

In making the tie, a pair of such cas'ings or jackets 3 are placed in the mold in `roper position near each-end, witlrthestiiienlng irons 2 extending longitudinally through them, l The concrete mixture is then dumped into the mold and compressed or tamped closely into and around the said '.ackets and stiffening irons, so that after t e molding operation is complete and the concrete has set, all of the iron work, including the ackets 3, is firmly connected Withthe concreteand forms a substantial part of the tie structure. -In operation the metallic jackets 3 take the brunt of the blow caused by the sudden passage 'of the locomotive or train over the track and distribute it along the tie, thereby -so far relieving the intensity of the shock as to revent the concrete fromy being cracked or liroken beneath the rail, as yit is otherwise likely to be. A At the same time'theweight of the tie is not so greatly increase as to expensive to be employed..

claim as my invention:- A railroad tie comprising a concrete tie .body and'jackets inclosing said tie body at 'render the tie impracticable to handle or` tog 2 esem 1 points beneath the track rail and provided i my invention, ax my -signature n preswith top plates forming seats for the rails and ence of two subscribing Witnesses, this 29 day pro`ectng beyond the sides of the jackets, 01E-July, A. D. 1906.

sai projecting ends being supported by ribs lH. H. CLQUGH. 5 extending up the exterior sides of the jackets, Witnessesz substantially as and for the purpose set forth. y WTILLIAM THORNBURGH In testimony, that I claim the foregqlng as MARTHA B. CLOUGH.
