Application filed Novenber 4 7b 5 7Z whom it may concern.-

it known that 1, Swan A. Swanson, a v citizen of the Unitel States, residing at Kellettville, in the county of Forest and State of Pennsylvania, have invented certain new and useful Improvements in li-aib road-Bail Fastenings, of which the follow ing is a specificatio My invention relates to new and useful improvements in railroad rail fastenings and the primaryobject of the invention is to provide a device of this nature which will prevent rails from moving with relation to one another or with the railroad ties. 1

Another important object of the invention is to provide a device of the above nature including means for maintaining the ends of ails in their proper relationship to one another. 1

Another object of the invention is to provide a device of the above nature with which the rails may be readily assembled, which is strong, durable, can be manufactured at a minimum cost, and is highly eiiicient in practice.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the accompanying drawings forming a part of the description and wherein like numerals are employed to designate like parts throughout the several views,

Figure 1 is a top plan of my invention' applied to a section of a track,

Fig. 2 is a vertical section taken on the line 22 of Fig. 1.

Fig. 3 is a longitudinal section through one of the ties, and rails associated there-v with, on the line 33 of Fig. 1. n

Fig. 4 is a top plan of one end of one of the ties with the rail removed therefrom,

Fig. 5 is a fragmentary vertical section through the same, and

Fig. 6 is a perspective view of one of my improved spliced bars.

In the drawings, wherein is shown, for the purpose of illustration a preferred embodiment of my invention, the numeral 7 designates a section of a railroad track, including the usual rails 8. .My improved tie 9 forming a part of this invention is adapted to be interposed between the usual ties at spaced intervals along the track, and I desire it understood that my invention may be applied to curved tracks, just as efi'ectively Specification of Letters Patent.

Patented Apr. 20, 192( 1919. Serial No. 335,676.

as it can be associated with straight tracks. One end 10 of each tie 9 is enlarged or provided with a relatively wide tread surface and these enlarged ends are alternately arranged upon opposite sides of the track as more clearly shown in Fig. 1 of the drawings.

As more clearly shown in Fig. 3 of the drawings, the upper face of my improved tie is recessed longitudinally as at 11 to provice the tie with a pair of oppositely aranged undercut portions 12 adapted for the reception of the outer rail flange of each rail, and consequently. will prevent any out ward movement of the rails. It is to be noted that each rail joint 13 of the rails is made upon the enlarged end of each tie 9. This arrangement-will materially assist in maintaining the ends of the rails in proper relationship the rail flanges are engaged in the relatively wide undercut portions 12. Inward movement of the rail upon the relative narrowest portion of the tie is prevented by fastening elements 14 such as spikes being driven into the recessed face 11 of the tie to engage the inner flange of the rail. The enlarged end 10 of each tie is, provided with'a longitudinally extending recess 15, which is V-shaped in cross section, the ends of the recess extending beyond the undercut portion 12 and the longitudinal edges of the rail flanges. The ends or": the recess incline in opposite directions from the bottom of the recess to the upper face of the tie, as more clearly shown in Figs. 3 and 5,'and it will be noted that the recess 15 is arranged directly under the free ends of the rails, for a purpose which will presently appear. I

The ends of each pair of rails which are arranged above the recess 15 in the tie, are joined by splicebars 16 which are arranged upon opposite sides of the webs of the rails and secured thereto through the medium of fastening elements such as bolts 17. Each splice bar is equipped with an outwardly extending flange 18 which overlies one of the rail flanges, the outermost splice bar flange being received in theundercut portion 12 of the enlarged end 10 of the tie. The outer edge of each splice bar flange, intermediate its ends, is provided with a depending V-shaped tongue 19 for reception and snug engagement within the recess 15, to prevent the rails from moving transversely across the tie. As the union 13 of the rail ends is made equi-distant from the ends'of the splice bars, and the tongues 19 are arranged intermediate the ends of the splice bars, it will be seen that they engage the edges of the rail flanges where they meet and consequently assist in maintaining the rails in their proper relation when united. The inner splice bar 18 is held rigid and in its proper position through the medium of spikes 20 or the like being driven into the recessed face 11 of the tie to engage the splice bar flange.

Although the sides of the V-shaped tongues 19 snugly engage the sides of the recess 15 when they are locked in position, nevertheless the splice bars may be readily removed from the rails upon removal of the fastening elements, as the tongues 19 may be moved up along the inclined ends of the recess 15 and longitudinally of the tie.

The foregoing description and accompanying drawings have reference to what might be considered to be the approved or preferred form of my invention. I desire it to be understood that I may make such changes in the construction, combination" and arrangement of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the ap pended claims.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent, is 1- 1. The combination with a tie having a V recess therein, of a pair of rails, splice bars joining the ends of said rails, and each of saidbars being provided with means to be snugly received in said recess to prevent the rails from moving transversely upon the tie.

2. The combination with a tie having a longitudinally extending recess therein, of.

a pair of rails, splice bars joining the ends of said rails, and each of said bars being provided intermediate its ends with V a tongue to be received in said recess, and said tongues being arranged to overlap the edges of the rails forthe purpose set forth.

3. The combination with a tie having an undercut extending transversely of the tie, said tie being further provided with a longitudinally extending recess, of a pair of rails having their outer flanges engaged in said undercut, fastening elements engaging the inner rail flanges, splice bars engaging opposite sides of said rails, and a tongue on each plate for engagement with said recess.

4. The combination with a tie having an undercut extending transversely of the tie, said tie being'further provided with a longitudinally arranged V-shaped recess extending upon opposite sides of said unuercut portion, of a pair of rails having their outer flanges engaged in said undercut, fastening elements engaging the inner rail flanges, splice bars engaging opposite sidesof said rails, and a ii-shaped tongue on each plate for engagement with said recess.

5. In combination with a tie having an undercut extending transversely of the tie, said tie being further provided with a lon gitudinally extending recess, of a pair of rails having their outer flanges engaged in said undercut, fastening elements engaging the inner rail flanges, splice bars engaging opposite sides of the rails, one of said bars being engaged in said undercut, "and a tongue on each bar for engagement with said recess.

6. The combination with a tie having a longitudinally arranged recess therein, said. recess being V-shaped in cross'section and having its ends inclined from the bottom of the recess to the upper face of the tie, of a pair of rails, splice bars therefor, and a V-4 shaped depending tongue on each bar snugly engaging said V-shaped recess to prevent longitudinal and transverse-movement of the rails upon the tie.

In testimony whereof I aflix my signature in presence of two witnesses.
