lb all whom it may concern:

Be it lmon'n'- that l, JOHN R. Devine, a citizen or' the United States, and resident of lllaultega'n, in the county of Lake and State 5 or' Illinois, bave invented a new and useful improvementin Metallic Railway-Ties, of which 'the following a specification.

,lily iure .tion pertains particularly to rnetellic rai ay which may be employed :is substitutes for 'the Wooden 'ties now in counnon andthe priinaryebject ef the inrentien' is te provide gaf-fiile lpossessing greater durability and ,capelbllof more succes, "i lly fulfilling its functions than any tie Vlicretotbre known; its use obriating the necessity of fish-plates and the *meansof fastenings now employed, .thus greatly enhancing the safety and eliiciency of the track- Way.`

The invention is illustrated in its preferred enibodin'ient in,y the accompanying drawing, in whichliigure l represents. :i broken plan sec# tional View of a railroad-track built in ac- 25 eordance with my improvement, the section being` taken as indicated at line l-l oi Fig. il; and 2, represents a vertical sectional View taken on tbe line 2-2'o`Fig. l.

In the construction shown A and B repre sent the ends of abutting rails of a track; (l, (Il, rail-bearings forming a portion ot' iny improved tie; D, a tie-rod joining the re1l-l bearings C, C1. l

Each of the rail-bearings C, G1, comprises preferably a downwardly dished circular base c, and' a rectangular shaped bead-portion surznountingthe base, which is provided with the longitudiinil inverted shaped channel rl, extenciling entirely through the heedpnrtion, forming jews e, el. The channel d is formed to receive the base and main portion of the web ci' the rail; the jaws e, e, 'extendingover the base or" the Tail as shown, providing a seat for tbe'rail. The abuttingrails nieet preferably in the ylongitudinal center et' the T-shaped channel. rllhe bear! v This lining is preferably a thin sheet all material `which may be .treated to withstand mbistnr' 12nd which may be readily 'bent to conform to one of the rail sides or web and the top el; the corresponding bottom iange ot' the rail'. Into the space on the ether side of the rfiil, l; place the block or ineniber g, prefe'rnbly thicker than "the member ,f; it is of course et angl torni 'te centorin yto adjacent side or the Mb and t of ilange et the rail. This block or i embcr g, is also preieably treated in a solution to enable it to withstand the effects ci' Weather. Gne end `of the block or member g, is tapered somewhat, as indicated at 71, to enable its being easily driven into place; the .member acts a Wedge to effect a close joint between the rail and the bearing.

Extending longitudinally of and prefer? face of the member g, which is adjacent to the web of the rail is a strip ofcopper it, which will come againstthe web et the rails t-o forni an electrical connection when deis a boss or extension j, which is provided with a hole or socket to receive the downn wardly bent ends of tie-rod D. The ends el' the tie-rod l), are each provided with a hole as at 7:, (see Fig. 2) which, when the tie-rod D, is in place, registers with a i'ransvcrse opening i-n the boss y', so that a belt er Cotterpin Z, may be passed through the boss and the ends of tie-rod l), tlius lockingthe latter in place against displacement. 'lbe bearing -nieinbers C, C1, are luis linked tei' inte pairs, thus binding the opposing bearings oi' tbe two rails tngether against any independent increment transversely of tbe one rail-support to settle Without all'ecting the other rail-support injuriously. The advantage of this feature -vfill be evident, when it is recalled that in the use ef the ordinary rigid tie, when one end ai the `tie settles, the other is thrown up, so lil-st aroclting action ings ay@ pl-efambly slipped@ the mils imm is produced, which soon the 1nthe ends thereof, the rails being provided Jury l0 Ill@ Pwd-09d 1 m with a sullicient number te give the desired I, prefer to provide the bottoni ol tne tsupport. The channel d, is made slightly larger than the base and web of the rail. Into the space between the top of the base and one side of the web, l prefer to place :i lining' j", of any suitable sounfl-deadenling material such as wood-liber, or the like.

with a boss or lug m, formed integral with the bearing (sce Fig. 2). The purpose of this lug m, is to prevent creeping of' the rail, and the lug takes inte a small depression er notch chipped er otherwise put into the unably -secured in a suitable manner to tine sursired. Integral with one side oi tbe bearing, l

track. The conne ion is such as to permit A shaped channel of the supports or bearings derside of the base of the rail. This notch can easily be chiseled into the rail while the track is being laid, as the notch need only be slight vto accommodate the lug or boss m, thus 4providing what may be termed an vanticreepmg mechanism.

The' bases of the rail-supports or railbearings, may be of any desired diameter, suited to the conditions of the road-bed. In forming the track, the rail-supports are slipped upon the rail-bases and suitably spaced and secured by means ot' the wedges. 'lhe wedges may be secured against` working loose by means of nails a, extending throughv a perforation which may be 'provided in the walls of the rail-support or bearing and taking into the wedges or blocks g; and as the point of the n'ail encounters the langeof the rail when being driven into place, it will bend to. one side, thus firmly holding the nail and block. -After the bearings or ties are properly located, the material of the. roadbed is thoroughly tamped in to till thespace in the hollow base of each rail-support, and the bases of the rail-supports are buried lin the road-bed, so-that the supports are thoroughly anchored. Because of the symmetry of each support, there is no more tendency for the support to work in one direction than in another', with respect to the roadb/ed, so that the tendency of the ties always isto keep their proper positions. Of course, in the supports or bearings Vintermediate of the ends of the rails, the wedge blocks g,

neednot be .vf-provided with the metallic or copper plate or strip, as this is only needed at the juncture of two rails. .V

Itis obvious that in my. improved construction no fish-plates and bolts are required for joining the ends of therails, and

no spikes are required for securing-the rails at their bases. lt thus appears that a fruitful source of loss and danger is removed by the use of my invention, and Athe cost of maintenance of the road is very materially decreased. Moreover, the whole construction is designed to'prevent undue relaztive movement of the parts and to deaden the sound incident to the passage of a train. It will be readily/,understood that with my improved'tie, the time and labor required to lay a track will be materially lessened.

It will be understood that changes in details of construction within the spirit of my invention may be made, and I do not wish to be understood as limiting myself to the exact construction shown and described, but

What I Wish to claim as my invention and .secure by Letters Patent, is 4 l. A tie comprising a rail-support having a body-portion provided with an inverted Tshaped channel, a hollow symmetrical base diverging outwardly and downwardly from the body-portion, means integral with said body-portion and taking into the channel to impinge against the rails to prevent creeping, and means whereby a pair of the supports are yieldingly linked together.

2. A tie, comprising a rail-support having a body-portion provided with a rail-receiving channel, a convex base integral with and extending downwardly from said body-portion, means integral with said support and taking into the channel and adapted tov impinge against the raiis to prevent creeping,

land mechanism removably connected with said supports whereby a pair may be yieldingly linked together. Y

3. A tie, comprising a rail-support having a body-portion provided with an inverted T-shaped channel, a hollow symmetrical base diverging outwardly and downwardly, a boss integral with said body-portion and provided wth a socket, a tie-rod whose ends take into the sockets of oppositely placed supports, and mechanism adapted to take through the boss and the ends of said rod whereby a pair of said supports are yieldingly linked together.

4:. A rail-support coinprisinga body-portion provided with a rail-receiving channel,

a boss extending into said channel and tak-l ing against the base of the rails, and a liollow symmetrical base integral with and diverging outwardly anddownwa'rdly from said body-portion.

5. A tie, comprising a rail-support having a body-portion provided with an inverted T- sha ed channel, an extension on one side of sai' body-portion provided with a socket, a hollow symmetrical base divcrging outwardly and downwardly from Asaid bodyportion, and a tie-rod whose ends take into the 1sockets of oppositely arranged supports where they are yieldingly locked in place.
