RAIL-ANCHORING MEANS.

Specification of Letters Patent.

Patented A11 28, 1917.

Application filed January 25, 1915. Serial No. 4,247.

To all whom it may concern:

Be it known that I, MILTON E. SMITH, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Rail- Anchoring Means, of which the following is a specification.

This invention relates to improvements in rail tie structures.

It is one of the objects of the invention to provide a sleeper supporting structure of maximum flexibility, and it is also a feature to provide such structure in a form which will maintain anchored rails in true gage relation.

In one embodiment of the invention the sleepers are in sections, preferably in alined relation, and means is provided for jointedly or pivotally connecting the alined or pairs of sleeper sections in such a manner as to afford maximum flexibility and reduction of the material used, and also, to maintain the rails anchored on said sleeper sections in true gage relation.

The invention also has to do with novel means for anchoring the rails to the sleeper sections, such means having incorporated therein a structure whereby alternation of the anchoring devices will structurally engage the rails in such a manner as to preclude movement thereof out of true gage relation.

A further object of the invention is to provide rail anchoring means wherein each device or anchoring entity only requires a single spike to hold such device in true position on the sleeper a novel feature of this phase of the invention having to do with alternation of spikes of the sleepers with respect to the sides of the rail engaged.

Other objects and features of the inven tion will be more fully described in connection with the accompanying drawings and will be more particularly pointed out in and by the appended claims.

In the drawings Figure 1 is a plan view of a rail tie structure embodying one form of my invention.

Fig. 2 isa sectional view on line 2-2 of Fig. 1.

Fig. 3 is a plan view of one of the sleeper sections, showing the same on an enlarged scale.

Fig. i is a perspective view of a rail chair plate.

Fig. 5 is a perspective view of a rail anchoring bar. FFig. 6 is an enlarged sectional view of Fig. 7 is a perspective view illustrating the application of the rail chair plate and anchoring bar to one of the rails.

Like characters of reference designate similar parts throughout the different figures of the drawings.

My invention includes companion pairs of sleeper sections 1 and 2, preferably although not necessarily formed of concrete, means being provided for connecting the sections of opposite rails in such a manner as to securely hold the sections in'fixed spaced relation.

As illustrated, each section has embedded therein a pair of yoke bars 3, extending longitudinally of the section and preferably provided with crooked or bent embedded terminals 4, to more securely anchor the yoke bars in the section. The remaining ends 5, of said bars, project from the inner end of each section in slightly spaced relation with respect to each other. To the projecting ends of said bars is attached, preferably by means of pivots 6, a gage link 7.

Now assuming that the rails are effectively anchored on the sleeper sections, it will now be seen that the latter are not only held from displacement in opposite directions from true gage positions, but that they are also afforded a limited degree of settling movement with respect to each other without imposing upon the sleeper structure any torsional or breaking strain. This is especially advantageous in cases where sleepers are constructed of concrete, and it will also be noted that a material saving is effected by reason of the fact that the sleepers are.

formed in sections and do not extend completely across the road bed. Heretofore in sleepers of this character, they have not been connected against displacement and therefore I consider this feature one of ex treme importance.

Next referring to the novel manner of anchoring the rail to the sleeper sections, 8 designates a rail chair plate on which the rails are directly superimposed. The plate 8 is provided with a rectangular spike opening 9 and also with an elongated fastener opening 10. The bottom of the plate 8 s grooved or recessed as indicated at 11. Be-

neath the plate and between the same and the sleeper section is interposed a rail anchoring bar 12. The bar 12 is preferably,

proportioned to fit in the groove 11 and lie flush with the bottom of plate 8. Bar 12 isprovided with a spike opening 13 which is adapted to register with spike openingv 9 when the parts are in the position shown in Fig. 7. A rail flange engaging lug'14e, preferably formed integral with bar 12, projects upwardly therefrom sufliciently to extend through opening 10 and overlap'one' flange 15, of rail 16.

Means are provided for initially anchor-- ing rail plates 8 to the sleeper sections,and

as shown, said means may comprise headed- T-shaped holders 17, having heads 18 beneath which the plate 8 is adapted to be forced into the position shown in Fig; 3.v I preferably employ four holders for each plate and the holders areshown embedded,

with respect to their lower ends, in the sleeper sectlons, the T-ends 17 servingto' effectively anchor the holder in the sleepers; It will be noted by reference to Fig; 1,

that the rail plates on each line of sleepers are alternately reversed in position-so as to cause lug 14 on one sleeper 860131011 130 face inwardly and to engage the outermost flange of the rail while the lug of another plate on another sleeper faces outwardly so as to engage the inner flange of the same rail. T husafter the rail anchoring devices, consisting of parts 8 and 12, have been anchored to the sleepers, they will function to structurally engage the rails on opposite sides thereof in such a manner as to not only rigidly hold the rails upon the sleepers and against any spreading displacement but also against any displacement from a true gage relation.

lVhen the parts 8 and 12 are in a rail holding position, the spike openings 9 and 13 will be in register and I preferably insert therethrough, and into the sleeper, a spike- 21, one for each anchoring device, and one only, this being also a feature of the invention. In cases where the sleepers are formed of concrete, I prefer to form the spike openings 22, in the sleepers, when the latter areprevent the spike from being pulledout when required. It will now be seen that the spike functions primarily to lock the bar 12 and the plate 8 in rail holding relation with respect toeacli other, a secondary function being to positively hold the free flange of the rail against any movement out of the fiXed lug 14 with which such spike acts in opposition.

It will now be seen that with the improved device" of my invention, the rails may be readily laid or taken up but that they will always be rigidly and securely held in position when once down. If for any reason there should be any clearance of an objectionable nature between the plates 8 and the sleepers, suitable shims may be driven there between or the heads 18 of the holders 17 maybe tapped so asto securely engage the plates 8. By reason of the presence of one spike'for each rail fastening device, it will. be seen that the plates 8 could not move longitudinally of the rail even though they mightbecome loose under the holders.

It is believed that the advantages and utility of the device of my invention will be fully understood from the foregoing description, and while I have herein shown and described one specific form of my inventi'on,-I do not wish to be limited thereto except-for such limitations asthe claims may import.

I claim:-
