I To .all whom t may concern/:I y

@Belit known l that `l, LAwnnNon ROLLAND lininoooin acitizen .-ot'fthe United States, re- .siding` `at Kelly` in the county ot' Socorro and `State oli" New lMexico, have invented certain `new `and useful improvements in lllailroad Ties,` ola-which the following is a specification, Ireference being had` to the aci co]npanying` drawings;

` This invention `relates tofrailway ties, and

lias'tor its object to provide a tie capable ot' being formed fromacompositionior imitation stone and provided with means for firmly securingl the rails tothe tie.

`llt; is another object o1 the invention to -providea railway tie composed of `a composition land provided `with substantial rail supporting means,.said supporting means including; means fil-'or holdingqa railfthereto, andmeansltor the `reception ofthe conventional form `ol? rail spike.`

It is a further object olithe inventionto provide `a rail tie o'li thischaracterincluding a metallic rail supporting i memberi provided `withwmeans `adapted to receive and-friction- ,ally engage a conventional form `ot `rail spike to hold said rail spi-ke in; engagement `with therrail, similar tothe wooden tie without requiring-1 the useol `wood orlike perishable material. i

VVit-h` these and other objects in view,the invention consistsin the improved construction; and arrangement oiiparts to be herein- `aiter, more` particularly described, 'l-'ully claimed and illustratedl in tlleiaccompanying drawings, in which Figure 1I is a Ilongitudinal sectionalA view not' a railway tie constructed in `.accordance `with .an enibodin'ient off the` invention;

`Figure 2 is a `sectional viewo one of the `rail supportingmeansand the spike holding 1 ineans 51 and Figure 3 is atop `plan View of one of the supporting, means,the spikesbeing shown 1n section, the. rail; indicated by dotted lines.

Referring' tothe drawings, designatesl a railroad tie of standard size composed oi concrete `or like composition, each end: portion of the tie being` provided with: rail supporting-members 6 and L7 `preferably constrncted vof metal, Each rail supporting` member comprises a base plate 8 relatively thick,I said plate being adapted to rest upon the top ot' the tie and is provided with a relatively large opening 9 and a small opening- 10. Depending from the lower face of the plate and formed integral with `the plate are side members 11 and 12, the lower edges oi said side members being concave 'for the `admission `oi' `concrete when the tie is formed. .Dependingsg` from and/formed integral with `the .lower face of the base plate 8 and invardlyiof` the ends of the base plate are end members 13 and 14, each of said end meni- 4lorsha-ving.;v a foot 15 andreiniorcing ribs 1G,.the t'eet 15 extending` outwardly of `the end members. Byl this `means a compartment 17 is formed for the reception oit concrete. `Portions `of `said concrete may be passed tln'oug'hthe openingv 9. Through the cooperation oij the projecting ends ofthe plate 8 `and 'the feet `15, additional compartments Vare formed ttor the reception of concrete, so that there is no possibility ot' the supporting, means being" disengaged from the tie. l Disposed inwardly of the end member 14 and` adjacent said end member isa wall 18, said wall cooperating with the end portions ci theside members and end member 14 to provide a* socket or compartment 19. vThe end portions of the longitudinal 'walls f-ormed by the end members' ltand wall 18 are provided with recesses 20, while extending centrally of the inner face oi the wall 18 an'dend member 1-1 are spacing ribs 21. These ribsare disposed inalinnment and centrally' olf the` socket. The socket 19 is intended to receive a pair lol' `resilient plates 22, each platebeingv relatively long and corresponding;` in width to the depth et the socket. The end portions 23 Aand 23a of 4each ot the resilient plates are extended at right angles to the bodyl portion et' the; plate and in parallel relation to` cach other, the distance between the outer face et the angularly disposed ends being' `slightly greater than the length et theisocket. :The end portions 234 and 23 `are arranged so that the extremities of said `end portions extend into the recesses '20 in the socket.' This positions the major portion ott each plate in confronting'` relation to the other.` Each spacing rib 21 is intended to engage the `central portion of one of the i plates, so as to provide a relatively small spacebetween the plates. This space is con- Isiderablyismaller than the thickness oli a rail spike. The recesses 2()` otx the socket also extend through the edges of the openings ot" the base plate 8. The lower ends o'l the recesses 20 are closed by stops 24e.

Carried by the upper surface of the base plate El, adjacent the end member 13 is a rail clamp 25, said rail clamp having the usual undercut beveled face 26 adapted to engage the base of t-lie rail. The clamp 25, however, is stationary.

1n the formation of the tie, that is, before the composition has been deposited in the mold of the tie, a pair of tie rods 27 are extended longitudinally of the tie, the ends of each rod being extended in angular relation to the major portion of the rod and through openings 28 provided in the feet 15 of the end members 14 of each supporting member. Nuts 29 are threaded on the ends of the tie rods to hold them in engagement with the. supporting members. Itis of course obvious that the tie rods are embedded in the tie, and in addition to the resistance offered by the concrete, serve to prevent spreading of the rails by preventing movement of the supporting members toward the ends of the tie.

When the tie is constructed, the supporting members are placed so that the clamps 25 thereof are disposed one adjacent the end of the tie and the other inwardly of other end of the tie. In other words, both ofthe clamps 25 extend in the same direction. rlhe purpose of this is to permit the rails to be lirmly braced and guarded against spreading, it being the intention t-o place one .tie with the clamps 25 facing in one direction and the adjacent tie with the clamps 25 facing in the opposite direction so that each tie alternates, thus providing a rigid structure for firmly holding the rails. The jaw of each clamp is intended to engage the base of the rail A in the usual manner. This positions the opposite side of the base of Athe rail closely adjacent the socket member and the resilient plates 22. The spaces on each side of the guide ribs 21 and between the resilient plates are intended to receive a conventional form of railroad spike B. In view of the fact that the space between the plates is considerably smaller than the spike, and the plates though resilient are not flexible, the spike B may be driven home the same as if the spike was inserted in a wooden tie.

The confronting faces frieti-onally engage the spike and hold it more. securely than itk would be held in a wooden tie. The

spacingl ribs 21 protect the plates from being` moved away from each other at their central portion and through the cooperation of the ends of the plates which are disposed in .the recesses 20, two sockets are substantially not cause movement of the spike. In addition to this, the side thrust of the tiain which is toward the ends of the tie is directed against the clamp Q5, the strain from the clamp being indirectly transmitted to the tie rod and the tie.

From the foregoing it will be readily seen that this invention provides a novel form of railway tie capable of being foi-ined from any composition used in the formation olf imitation stone. The tie is also provided with metallic rail supporting means capable of using the conventional forni of rail spikes. In addition to this, the tie includes means for preventing spreading of the rails without causing the strain to be applied to the conventional form of spikes used as part ol the fastening means for the rails, and wherein the fastening means are init-affected b v the disiiitegrating forces which render the present type of rail fastening means inellcient.

`What is claimed is:-

1. A railway tie embodying a composition body, a metallic rail supporting member enibedded in each end portion of the tie, `ach rail suppoi'tiiig member consisting of a. nietallic shell adapted to receive a portion ol the composition, a rail clamp carried by one. end portion of the shell, the other end portion of the shell being provided with a socket, resilient plates extending longitudinally of the socket in spaced relation to each other and the adjacent walls of the socken.

and rail spikes clamped between said platesl within the socket.

2. A railway tie comprisingl a composition tie or body member, a metallic supporting shell embedded in each end portion of the tie, said shell including a base plate, walls depending from the lower surface and inwardly of the edges of the plate, certain ol said walls having anchoring feet, one end portion of the shell having a rail clamp, the opposite end portion having a compartment formed therein, spacing ribs projecting from the longitudinal walls of the compartment and centrally of the compartment, recesses formed in the corners of the compartment. and a pair of resilient plates having angular ends, said plates being disposed in the socket in confronting relation, the ends of said plates being disposed in the recesses, and rail spikes driven between said plates on each side of the guide ribs for securing the rails to the shell.

In testimony wheieof I hereunto allix my signature.
