arl exact. desi-rlptiou as will enable any;

one skilled iu the arl to hit-h it :ip|n:rtain.-.l lo make and uw the same, reference being had lo the :wrompanying drawings, forming parl of this .qweilieatioin .\l.', invention relates lo :i railway tie und more |n|rlieularl \Y lo that ela:-.-: ol' lies com posed ol' :l holly portion of rement or couerele iut-using metallic reinlori-ement 'I`he ohjeel'of my invention is lo .so eouxlrucl the reinl'oreenielils that while they are comparatively imple the tie will he thoroughlyl reinforced .-o that il may lie handled like a wooden tie without danger of cracking the coulent or concrete.

.\nolhe|' ulijecl of my invention 'is lo provide improved means for securing the rails to the tie.

lu the neronunurving drawings, which illustrate one form of liemadq;v iu :wcordanec with my invention Figaro 1 is a side view lallowing the metallic reinforcements, Fi 2 is a longilmlinal central section througx the complete tie; Fig. 3 is a top plan view; Fig. 4 is a section on the line 4--4 of Fig. 2; ["i f. o is a section on the line 5-5 of Fig. 3 an( Fig. t is a section on the line (i of Fi r.

llike marks ol' reference refer to similar parta in tho several views of the drawings.

l0 reprcsenlsa uwlallie easing forming parl. of thc metallic reiuforceimrut of the tic and conforming substantially 'to thc outside dimensions of the tic. This easing l0 is preferabl made 0f what is known as expanded meta as shown in the drawin s. lt may, however be made of any. suitab e perforated metal. xlhe casin is but ali htly smaller than the outside imensions o the body 11 of cement or concrete in which it. is elnbedded so that, it will thoroughly protect the said body 11 of concrete against cracking. In order to further reinforce the tie the casing 1,0 is provided with a. number of partitions l2 as shown in Fig. 2. These partitionsi12 are alternately inclined from the upper to the lower w'alls of the casing 10 so as to divide the interior of the casing into a nurl'iber of irism shaped compartments. In order to sti l further reinforce the tie use a ir of reinforcing bars 13 which are laec in the lower portion of the casing 0 and also a pair of reinforcing bars 14 which are placed in the u per part of the easin 10. The central po on of these bars I-l is ent downwardl so as to make contact ,vilh the hars 18, as s own in Fig. 2 and the liars lil and 14 are secured togethx at their central parts in any suitable manner as for 'instance hy heilig wrap )cd by hoop wins 15 as shown in Fig. 2. he ends of the bars l ami 14 are also connected b the wir ln addition lo the casing 0 and bars 13 and I4 the body l1 of cement also incases lwo pairs of metallic upright! 16, one pair being placed adjaceutvto eacheud of the lie. Each pair of uprights 10 is joined at the lower ends by means of an integral cross-piece 17.

ln eaeh of lhe uprightx lt' is formed a Imre In which is square in crisis-motion and i.- slightlvtwisled. lhe twist hein ald'v about one quarter turn inthe en h of the Imre. 'lho bore is made of su icient length lo receive u spike 1li similar in sine -to the ordinary railway spike. I tiud that hy slightlv lwistin the hare of the upright lli the spike lli wili'nol be turned out of the boxe hy tho straight upward all ofthe rail. It may, however. lie reniov by a suitable lool h v means of which the spille may he given radial motion nl lhe same time it is turned upward. 20 represents the rail and l a lie plate placed between Athe ruil 2l) and the upper ends of the uprights 10. The spikes l!) may either be formed with a slight twist corresponding to the bore of the upright lt or they may he made straight and hy being heated when they are driven in the neem-sary twist may be imparted lo them. Having fully describml my invention, what l claim as now and desire lo secure by Letters Patent of the United States is:

1. [ifi a rJillway ti, the combinaticnwith a )er oral meta ic casi aulistantially to the exteriorno the til, 0f l pair of reinforcing rode ih the' lower grt of the casing, and a second pair of rein rcing roda ia the upper part of said ling said upper and lower in contact and connected at their central 2. In'a railway tie, the com ination with a perforated metallic casing conforming substantially to the exterior of the tie, a pair of reinforcingroda in the lower part of said casing, a second pair of prefcrcasing, a pair of rein orcin rods having their central portions bent downward] and connected to sait". first named rein rcing rods.

8. In a railway tiez the combination with a perforated metallic casi conforming subatantially to the exterior o the tie, of a seriea of op itely inclined perforated inetallic partitiona dividin the nterior of said rods in the lower part of said casing an a aecoiid pair of reinforcing rods in the u per part of said casing, aaid aecond ir o rods bent downwardly in their central ions :ind secured to said first pair of a.

In a railway tie, the combination with a body of concrete, of metallic' reinforcements therefor, a pair of metallic nprighta embedded in each end of the tie, each of aaid uprights being provided with a alightly twisted bore of angular cross-notion and spikeaadiipted to conform to the bore of said up .te 1and liloldthe raila by friction.

I. ii a railway ti'e, the combination with a body of concrete, of metallic reinforcements therefor, ii pair of metallic upri tx embedded in each end of the tie, ea of said :rights bei' ig provided with a alightl twist re of angular cron-acetico the lower end of each of laid pair of iiprights being connected by an integral cro.

ieee, and pikes iidapted to conform to the re of sai uprights 'and hold the rails by friction.

0. In ii railway ticz the` combination with ii perforated metallic casing conforming substantially to the exterior of the tie, of n series of op itely inclined rforated metallic partitions dividin the interior of said casing, a pair of rein orcing rods in the lower part of said casing, ii second pair of reinforcin rods in the upper part of said casing," said second 'ir of rods being bent downwardly in their central portions. and iicciii'cd to said first iiir of rods, a piiir of metallic u ri ite` ein ded in each end of the-tie,ea o 'said u rights being roiided with a slightly twist 4bore of iin ar croes section, .lower end of each o said pair Fof iipriglitii being connected by integral cross pieces, and spikes adapted to conform to the bore of said uprigbts and hold the rails by friction. v

In testimony whereof, I have hereunto set hnnd and axed my seal in the presence in oftlic twg subscribing witnesses.
