COMBINATION BAIL-JOINT: SPLICING AND SUPPORTING PLATE; 7

Application filed December15, 1926. Serial N5. 154,895. 2

This invention relates to rail supporting devices andmore in particular to combina: tion rail-joint J splicing and supporting plates. k i I The primary .objectof this invention is to provide a combination rail-joint splicing and supporting-plate whichis so Constructed and proportioned as to prevent sagging of the ends of connected rails during the passage thereover of the locomotive and car-wheels of a train, thus relieving said rail-ends'o'f the tremendous strains they are subjected to and reducing the wear of said ends to a degree substantially equal to that of theless exposed portions of the rail. Another object of this invention-is the provision of a combination rail-joint splicing and supporting-plate which enables-the elimination of the bearing-plates commonly employed in railroad track construction for the purpose of increasing the bearing surface of said rails on the ties in order to prevent any crushing pressures thereon. Still another object is the provision of such a combination splicing and supporting device which permits the safe and efficient joining of rails with the minimum number of parts and with great saving in time and labor. Yet another object of this invention is to produce such a device which is well adapted for quantity manufacture by the usual processes of hot rolling and bending as they are performed in steel mills, in particular. Additional features and advantages of this invention will be dealt with in the course of the following description considered in connection with the accompanying drawing which forms a part of this application, and in which:

Fig. 1 is a perspective view of my combination rail-joint splicing and supporting plate, showing the connected rails in dot'an'd dash lines.

Fig. 2 is a cross-sectional View taken on line 22 in Fig. 1.

Fig. 3 is a similar view taken 011 line 3-3, Fig. 7

Referring to Fig. 1, the preferred construction of my combination rail-joint splicing and supporting-plate consists of the bearing-plate 1 and the two splice-bars 2. The bearing-plate comprises a sole-plate 3, of ample Width to accommodate the rails and the splice-bars, and having one of its longitudinal edges bevelled off, as shown at i, to facilitate the insertion of the bearingplate under the rail. Opposite said bevelled the rotation of the bolt.

Ad jacent the rib 5 is a longitudinalrflange 8 the top 9 of which is tapered outwardly to agree more or less with the bevelled edge 4: and for theldual purpose of reducing the weight of the plate vvand facilitating the drainageof rain-water.

the bearingplate is providedwith an mtegral, upwardlydirected, reinforcing r b The combination rail-joint s'plicing and supporting-plate and railsare secured' to the railroad ties by' means of spikes" 10, of the usual type, which are inserted in registering recesses and apertures 11 provided respectively in the edges of the lower flanges of the splice-bars 2 and in the sole-plate 3. Although these fastening means satisfy the ordinary tralfie and load conditions, if desired, and where the railroad service is especially heavy, additional recesses 12 may be provided in both longitudinal edges of the bearing-plate for the insertion of another set'of spikes 18. These additional recesses or apertures are not'visible in the farther side of the supporting-plate in Fig. 1,but are plainly shown in Fig. 2. Moreover, as shown in Fig. 3, the rigidity of. the complete joint construction may also be materially increased by providing midway. of each splice-bar a circular hole 14 in axial alignment with a square hole 15 provided in the sole-plate, for the insertion of a bolt 16 having preferably a square shank 17 adapted to lit in the square hole 15, thus preventing These bolts are secured in place by meansof nuts 18 which rest upon suitably bevelled washers 19. The splice-bars are fastened to the rails by means of the through-bolts 20 inserted through suitable and registeringv holes 21 provided in said parts.

My combination rail-joint splicing and supporting-plate may be made of suitable length to bear either on two or three ties.

. In View of the fact that these plates may be port the rails intheir entire length. 'Under certain circumstances this feature may prove very valuable where the rails of a track, owing to increased traflic or increased weight of the rolling stock, should prove too weal: towithstand such increased loads. In such cases the rails could be readily strengthened at relatively lowcost and expeditiously.

I do not wish to limit myself to the exact form of the parts herein shown and described, as it is evident that same may be changed withoutdeparting from the spirit of my invention as defined in the appended claims.

I claim:

1. In a rail joint comprising two abutting rail'ends, two splice-bars and holding down spikes, the combination of a substantially fiat sole-plate having two bevelled longitudinal edges and an integralupwardly directed stiffening rib positioned adjacent and par- "llel to one of said bevelled edges, saidsti'ffening rib having two steps on the inner side thereof, the lower step acting as an abutmentfor the base of the adjacent splice-bar and the upper step being disposed outwardly of saidfirst step to provideroomfor the insertion and extraction of said spikes.

2 In a rail joint comprising two abutting said sole-plate having at each side of the .cen-

ter-line thereof two rows of apertures adapted to receive said spikes, the inner'rovvs of spikes serving to secure together the splicebars to the sole-plate and the outer rows of spikes serving to hold the sole-plate to the rail-ties, said stiffening-rib being positioned intermediate an inner and an outer row of apertures.
