To' all wL'om it'may concern.:

Be-it known that I, JOHN W. CLARK', Jr., residing at Provo, in the county of Utah and' `State of Utah, have vinvented certain new and useful Improvements in Railway- Ties; and I do hereby declare thev following. to" be a full, 'clear, and exact description of the same, reference being had to the accompanyingdrawings, forming a part of :this specicatio-n, and to the letters of reference marked thereon.

This invention relates to railway ties and .has for its object to provide a metal tie with which ythe use of Wood or its equivalent may be greatly economized,l the strength vof the tie increased, and the advantages incident to the use of wooden ties, in so far as resiliency and adaptability-'forthe insertion of rail fastenings, be secured.

rlhe invention consists primarily in a railway tie having a metal bo'dy provided at itsends With chambers for the reception of blocks or sections of wood or equivalent .transverse planes material and with recesses or' openings in which the rails may be seated 'directly uponl the wood.

The. invent-ion further consists in a tie of. the character mentioned Jformed in sections which are loosely or pivotally connected together in such manner that the ends may ldrop independentlyso as to seat irmly upon the underlying road'bed wit-hout displacing or tilting the opposite end, whereby the rails may b e maintained in more accurate alinemerit and buckling prevented.

The invention further consists in certain noveldetails of construction and combination and arrangements of parts, all as will be now described a d pointed out particularly in the. appende claims.

Referring to the accompanying drawings,-Figure l is a perspective view of a tie' embodying the present improvements, one of the chamber closing end plates being removed; Fig. 2 is' a similar' view of a slightly modified construction, with both of the end plates in place; Fig. 3 is a detail perspective view of a torni of looseconnection between the ends of the tie which may be employed in lieu of that shown in 'and Figs. il, 5 and 6 are sectional views in through the end chambers of ties having different cross sectional shapes.

letters of reference in the several igures indicate the same parts.

igures and y The bodyA of the tie embodying the pres-- ent improvements is preferablyy formed up of sheet or plateinet'alfWit-h a substantially flat bottom vportion A and sides Biorming a trough-like structure which .may be of less height at the center than at the ends. At

the ends the trough-like structure is adapted vto receive blocks C of wood, fiber or equiva-l lent material which will substantially till the ends of the trough-.like body of the tie and be held ir'mly in lace therein by the sides ofthe trough and y overlying and end portions `to be noW described;

The rails are adapted to seat ldirectly upon the blocks C, and in order .to permit of this the sides of the trough are cut away, at points b corresponding to the bases of the rails, thus 'forming shoulders on the metal which will prevent lateral displacement of the rails. To upper edges of the trough-like body B are bent over the top of the blocks G as at B', and at the inner ends of the blocks an angle iron or plte D is provided for completely inclosing said ends of the chambers, it being understood that the angle irons D are preferably united to the sides and bottom ot' the trough-like body so as to formv a rigid structure. thus formed are open for the ready insertion and removal of the blocks C, but in use, said outer ends are intended to be closed by removable end angle iron cover plates E which may be conveniently held in place by a tongue e adapted to enter an opening or slotc and a top E adaptedto overlie the block between the flanges B and be secured by a spike driven into the blockthrough an opening c2. 1With this construction of tie the rails may be held in place by ordinary spikes inserted or driven through slots or recesses in the edges of the plates D nd E, whereby the tie will-be adapted for use in the ordinary manner, with the advantage that when worn on one side, `the blocks may be reversed in their chambers. Unless badly rotted, the blocks will last practically twice as long as they would if not reversible. l

In the preferred construction, the troughlike body of the tie is made-in two. sections which are so`connected togetherA that they will be held-against relatively longitudinal movement or independent upward movement at either end, but will be Jfree to drop at either end or rise at .the center should the conformation of the road bed be such as to give additional strength, the

rlhe outer ends of the chambers necessitate this end, when in course of construction or during the passage of loads over the railway. i

4Conveniently7 the connection between the two sections of a tie is in the form of a hinge orpivotal connection known as a rule joint. As shown in Fig.v l the joint is formed by 4l'iearings' F, F on the two sections through which a bolt or. pintlef mayl be passed, as will bereadily understood, While shoulders f vlimit the pivotal movement in one direction, as shown in Fig-1. As a modification of the form of joint shown in Fig. l, that shown in Fig. 3 maj7 be adopted, the end of one section being telescoped into the end of the other section, andthe side walls B connected by a 4transverse bolt G, the arrangement of the parts being such as to permit of the movements described in 'connection with Fig. l.. The bottom of the outer section may be out away below the bolt sufficiently to permit either end to swing downwardly and thevend of the inner section form the stop to prevent upward swinging movement.

4In Fig.' 2 the tie is shown rigid from end 'to end, and-in this instance the chambers forto useythus, as shown at the left end of Figs. l and 2, one side of the opening is substantially straight vwhile the' other sid'e is curved, so as to receive a rail base having on one side a curved conformation which will give additional rigidity to the rail, and lock the rail'andv tie together against relative' longitudinal movement without 'increasing the strain on lthe retaining spikes or.A fastenings. I y

While in Figs. land 2 the cross sectional shape of the chambers at the ends of the tie is substantially rectangular it will be under stood that said chambers may be of any preferred or cesired shape in cross section.; thus, as shown in Fig. 4t, the cross section is in the form of a trapezoid, the two side walls I inclining inwardly from the base. In Fig. 5 the end' chambers are of semi.-cylindrical form, the top surface l. eing` ':urved as atll, and in this instance where additional bearing surface. for the rail is desired, the blocl: maybe cut down as indicated by the dotted line in Fig. (l, the 'cross sectional shapel is rectangular" but the side walls Llare located a 'much greater distance apart than in Figs. l and. and thetop plate Z i'sheld beneath the overlying` shoulde or flanges Z of the side walls L l ln all of the illustrations it will be understood that the rail seats directly uponthe wooden blocks held in the chambers at the ends of the tie, v.and 4,in theprefered construction the pressure is transmitted down wardly through the said blocks to the bottom plate of the tie. In other words, the side walls of the tie are relieved lof downward'pressure from the rail-base, by being 'cut away on each side at 4as before ex! plained. v

ViThile the spikes holding the rails to the blocks will Aafford all of the' strength which is usuallysecured b v such fastening devices', the present invention contemplates the utilization` of the'shoulders formed by the side walls on each side,of the rail opening as a means whereby lateral movement of the rails 'will be effectuallyprevented even though there should vbe some looseness between the.

ends of the block and the ends of the chambers.

In lieu of wooden blocks it will be understood that the invent-ion contemplates .the

use of blocks of other materiahsuch for-.in-v stance, 'as iber or compressed paper, and-it will be understood in the claims that where awooden block is specified such other material is considered as the full equivalent thereof.

'In laying tracks, long ties extending across from rail to raill` may be alternated with short chamber sections with their contained blocks under each rail.

. Having thus described my invention, what I claim and desire to Isecure by Letters :Patsy ent of tie' United States` is:

l. A metal railway tie bedarf' formed 'of sheet metalwith a iiatbase and upturned sides constituting a trough like structure,`

the end portions of said sides being bent in wardly to form chambers forthe reception of wooden blocks, and angle iron plates for closing the ends of the chambers and overlying` th-e blocks between the int-urned portions of the sides, said plat-es being provided with openings for the ,reception of spikes for holding both the plates and rails on the block. i

Q; A metal tie for railways formed of sheetI metal with a substantially fiat/bottom, upwardly extending side walls of `great-er height at thc ends than at the center, the end portionsof said sidewalls being turned inwardly to form chambers for the reccp- 'tion of wooden blocks, said chambers each vhaving a 'trai'isverse opening 'in the top of the same for the A'recejtion of the rail bases, and the ends of said lianges adjacent said openings forming shoulders for limiting the lateral movement of the rails and angle plates for closing the ends of the chambers and overlying 'the blocks between, the inturned portions of thesides ofthe tie.
