ATTORTEY metal MILEDEN S. MONDAY, OF CAREY, OKLAHOMA t METAL RAILWAY-TIE.

Specification of Letters Patent.

Patented May 14, 1918.

Application filed January 4,1918. Serial No. 210,315.

.7 '0 all whom, it may concern Be it known that I. llhmaoex S. Mummy, a citizen of the United States, residing at Caney, in the county of Atolra and State of Oklahoma, have invented certain new and useful Improvements in Metal Railway- Ties, of which the following is a specifica tion.

This invention relates to railway ties, ani it relates especially to an improved form f tie.

one of the objects of this invention is to provide a metal tie that is comparatively light and inexpensive, while being strong, igi-gid, durable and perfectly eflicient.

.tnother ohjcetis to provide a tie of this character that may he formed either by pressing it from blanksol' sheet metal or by casting it inte 'rally.

Another olnect is to provide means to render impossible the spreading of rails secured on ties of this character.

Another object is to absorb the shock or jar caused by the travel of rolling stock along. the rails that are supported by my improved ties; and,--

Another object is to combine means for retaining the shock. absorbers in place and for staying the sides of the tie so as to prevent collapsing of the tie when it is subjected to an exceedingly heavy load or severe shock.

Other objects and advantages ma become apparent to persons who read the ollowing details of description in connection with the accompanying drawings in whieh,-

Figure 1 is a top plan view of the tie with fragments of. two rails secured thereon Fig. 2tis a sectional view taken along the line 22 of Fig. 1

Fig. 3 is an end view of the tie with a fragment of a rail secured thereon; and

Fig. 4 is a perspective view of portions of the tie.

Referring to, these drawings in detail, in which similar reference characters correspond to similar parts .hroughout the several views:-,

' The main body of the tie is preferably in the form of a channel beam, or U-shaped in cross section, the height and width being approximately equal. The horizontal lower sido'll of the tie joins the vertical sides 12 at right angles. and wide horizontal flanges 13 a e formed on the uppo r edges of the sides 12 and extend in opposite directions therefrom. Each end portion of each llange 13 is provided with a depression or rail seat 14 and with shoulders 15 at opposite sides of each rail seat.

Combined partitions and braces or struts flange 17 and through corresponding ap-' ertnres 19 of thebody 10. for securing the members It; in spaced relation within the body 10, so its to form a housing for a cushioning member or shock absorber 20. The member 20 is preferably of wood for the sake of minimizing in the cost of production, and also for the sake of resiliency. This member is cubical and is. therefore. easily and economically obtained by sawing :3. rectangular beam of \vood inlo proper lengths. The grain of the wood may be either horizontally or vertically disposed. and the blocks may he a little higher than the depth of tho body ll) at the seats l4 so that the rail may primarily and normally rest on the blo k independently of the seats 14; but when an exceptionally heavy load is placed on the'rails. the seats 14 supplement the blocks 20 in supporting the rails and their load. liar-h housing formed. by the elements l2 and 16 effectually confines its block 20 in registry with the rail seats 14, while the shoulders 15 prevent lateral movement or spreading of the rails at their bases.

In order that the rails may be securely retained between the shoulders 15, I pro vide combined alultments and keepers 21.

each of which is formed integrally and comprises a flange 22' and a rail-engaging element 23. the latter comprising a surface24 which engages the base-flange of the rail,

also a surfaee'Qfi, which engages or abuts against the web of the rail. The members 21 are each secured to 0% of the flanges 13 by means of a bolt 26 that extends through an aperture of this member and through an aperture 27 in the flan 18.

Each tie comprises eig t of the members 21, four at each end portion; and for securing a rail to one end of the tie, t wo complemental pairs of these members are em ployed In securing a rail to one of these ties, the

base flange of the rail is placed on the block lork :20, so that liainlnel-ing" :20 and is therehy held slightly spaced ali ve the seats H, while the edges of the ba e flanges are between and against. (or only .-|li;, rhtl y spaced from) the shoulders 15; the members 21 are then plaoed in the respective position shown in Fig. l; and the hohs 26 are then placed, and the nuts thereof a re tightened until the memher '31 are tightly secured on the tlangtw 13. In thus tiglnening the holts 2n. the outer edges of the flanges It are drawn upward, their inner edges hein; held rigid h the hloek 12th .'-:o that these outer edges may touch or nea1'| touch the hastof the rail. Now when an exceedingly heavy weight on the rail eon:- presses the hlock J0. it also depre se the outer edges of the flanges lit. so that the latter eoiiperate with the liloek "30 in proriding a cushion seat for the rail. It will he seen that the inherent spring aetion of the flanges 1Z5 cooperates with the metnlrer 2| for eontinualtv holdingthe rail on the of the blocks h the rails is efl'eetually o'n'iated, and no rattling or jarring will occur as when ties of ordinary construction are used.

Zach member 31 is provided with a shoulder :25 which cut'iperates with the Sl'tOllltlUl'S 1.3 for preventing lateral nun'ement 0f the contiguous haw flange. Iaeh flange 22; lie llat against the contiguous vertical portion 1; and prevents turning of the member :21 around its holt 2t and cooperates with the memhers lti for holding the block it) in proper relation to the tie and rail.

What I t-laim as Ill V invention is:

1. A metal tie. oniprisiug a ehannel healn having opposed outwardtv extendingllangcs diaspowed to form rail seats. and a rail securing member holted to each flange at the end\' of the rail seat. thereof. said lnemher (-omprising' a depending portion to engage the inner fare of a side wall of the channel heam. and an inner element to extend over the hase flange of the rail and engage the web thereof.

2. metal ti c mprising a channel heam ha ring opposed outwardly extending flanges disposed to form rail seats. a resilient blne k within the channel beam to support the rail. hraces Ftt'ttttd to oppo ite vertical walls of the channel heain and in contact with 0pposite side of thtyhluek. and a rail securin; :nemher liolted to ea -h flange at the end of the rail seat thereof and eomprising' a depending portion to engage the inner face of a side wall of the ehannel beam and a side of the hloek. and an inner element to extend over the hase flange of the rail and engage the weh thereof.

In testim ny whereof I a tiix my signature in [)ltHt'ltt'e of two witnesses.
