(C1.` 23a-191') The invention relates to rail joints. The` members I terminate below the heads of One objectv of the invention is to provide a the rail so theeloadingon the rails will be transrail joint which is efficient in use and which is mitted lthrough the j web to the joint. V The adapted to prevent cracking of the rail web. bridge-plate c has ,a flat top-face I4 which fits Another object of the invention is to provide against thebottom-face of the rail flangesiedges 5 an improved rail joint which comprises splice- I5 which are flush with the edges of thebase bars and a bridge-plate having its lower side proanges and a central reinforcedk or thickened vided with reinforcement substantially coplanar portion I6, the bottom-face II of which is flush or iiush with the bottom faces of the members or substantiallycoplanar with the bottom faces l0 of the splice-bars which underlie the base flanges of the inturned; members I3v of the splice-bare 10 of the rail soV that both the bridge-plate and the Betweeni'ts reinforcement `I'I and edges I5 the Splice-bers may be uniformly Supported upon the splice-bars are inclined upwardly outwardly, ties. as at I8, kand the abutting faces of members I3 Aliether Object Of the invention iSztO prOVide arecorrespondingly inclined for wedging engagea rail jOint Which @OmpliSeS Splice-bars and a. ment.

The thickness of the reinforcement I6 of the bridge-plate and the combined thickness of the marginal portions of the bridge-plate and members I3 o-f the splice-bar, is substantially equal to the thickness of the usual tie-plate so that the joint will support the rails in alignment with the support furnished by the tie-plates on the ties between the joint. l

In the modification illustarted in Figs. "6 and 7, the invention is exemplified 'in a" rail-joint adapted to Support the ends of the rails when they meet between ties. vention the bridge-plate and the splice-bars are of the same construction hereinbefore described,

except that the splice-bars are -provided with`v` downturned anges 2|. Bolts 22 extend through low the bridge-plate and the rails. Thesplicebars comprise members Illa for engaging the web, members IIa for providing loading and Wedging engagement between the splice-bars and the base anges, members I2ab extending around the edges of the base flanges of the rail and the sidelr'nar'- gins of the bridge-plate, and members I3EL having wedging engagement withtheA side-margins of the bridge-plate. The flanges 2I, depending from the inner ends of, members |35; adapt lthe joint for supporting the rail-ends between, and independently of, adjacent ties. vThe bridgeplate in this construction isY also held against endwise movement by bolts 20.

In practice, `the splice-bars and bridge-plate can be formed of rolled stock. y The construction is one which provides' a -joint kof comparatively light weight, because it is possible to use lighter and shorter joints than those used instandard constructions. It is also possible to apply th rail joints to existing' tracks with the usel of itie-` plates which correspond Ain thickness to -the bridge-plate. While four bolts have been shown In this form of the in- A 2,220,179 bridgeplateyv avoids the necessity of forming for clamping the splice-bars to the rails, in some instances two are sucient, the length of the joint being varied according to the weight of the rails. t

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scopeof the appended claim, without departing from the spirit and scope o-f the invention. i

Having thus described the invention, what I claim` as new and desire to secure by Letters Patent is:

In a rail joint, the combination of rails each comprising a head, a web, and base flanges, splice-bars spanning the rails and comprising `members having vertically extending inner faces -for clampingagainst the sides of the rail webs, members having loading engagement with the iianges 2I and draw the splice-bars together'betop of the base flanges, members underlying the rails and members extending around the outer edges of the base flanges, the members of each splice-bar being integral, a bridge-plate l underlying and abutting against the bottom faces of the railsjthe underlying members of the bars having: their inner sides spaced apart and having wedging engagement with the bottom faces of the margins of ,the bridge-plate, the bridgeplate having increased thickness between the inner sides of, and terminating inwardly of the ends of', the splice-bars below the rails, clamping bolts extending through the splice-bars beneath the rails and outwardly of the endsof the bridge-plate for confining the bridge-plate against endwise movement, and bolts extending through the vertically extending members of the splice-bars.y and the webs of the rails, the underlying members being provided with downwardly extending flanges outwardly of and at the sides of the portion of increased thickness on the bridge-plate, andebolts extending through said flanges. f Y
