REI NFORCED-CONCRETE TIE.

Speetcatton ot Letters' Patent.

I'utennted Apr. .10, 1010.

Application tiled lay lll. 1909. Serial No. 496.001.

To ull whom if 1m: n/ ronrfrn.'

Bc it known that l. (n.\nnn.n:s li. llonnnnzx, a citizen of the United States. residing at Chicago, ill the county of ('oolt' and Stute nnf Illinois, lnave invented a new and not-ful lnui provement in Reinforced(ioni-rete 'l`ie-, of i which the following is a slweiticatou.

My object. generally `lated. ito provide ln improved enmitluetion nl' conn-rete lic. l0 which shall be economical to nnnannufacture, 0f construction, and hi rlnly useful in accomplishing tlne purpose o constructions of this t pe. l

Spec cally stated, nny objects are to iro- 'l Vide l construction of tie which shall a ord the resiliency desired, witlnonnt sacriticiug rigidity 0f structure; to provide n forlnn of member which, inn itself, shall beollapsn le into compnet connditionn. there o tinltallation.,4 and which, when ineased in to form the strengthening means .fthe tie, shall serve very etlectnnally as a for the concrete; and to pro- Vide improved means for supporting the rail the tie and on the reinforcing member.

In the aceompln ing drawings. in which I have illustrated t ne preferred ennlmdinnnent.

of my invention-Fi ered is a plain view of 80 l section. of track Fiormed with ties connstracted ln accordance with my invenntionn.

Fig. 2 is s view inn snide elevation of one ot' the similar ties illustrated in Fig. l, the rails being shown in section. Fig. 3 is an ennlarged sectional view of one end of one of the three similar tics illustrated .in Fig. -l, the section being taken as indicated at. the line 8 on Fig. l and viewed in the direction of the arrow. Fig. 4 is an enlarged section t0 teken st the line 4 on Fig. 2 and viewed in the direction of the arrow. Fi r. 5 is a perspective view ol' one of two nnnnilar molds preferably ennnployed in connut-.tion with each tie for forming its amr-rete heads. Fig. t' is l. perspective view of thc reinforcing nnnennnber for the tic, plates eoi'nlwratinng witln this reinforcing nnnennber and nueanns for smearing the rails to the plates, these parts being ,shown in disassembled but related connlntion; and Fig. 7, a sectional view of one-of the lates with a rail fasti-.ned tlnereonrby snot ner form of fastening means. i.

The reinforcing member, or frame, for the concrete, in its pret'errtxl ennlmdinnent.. is

the rod 8 being screw-threaded at insoppo- '15 formed of three rods 8, t) and tti extending generally in parallel relation to euch other,

site ends as represented at l1 and l2. he opposite ends of each of the rods t) annd l0 are detlected as indicated at 13 and 14, their 63 extrennnities` terminating in eyes l5 which surround the ends of the rod 8 as represented, nuts 16 screwinn v upon the opposite ends of the rod 8 and t"bearing against the cvcs 15, preferably with sutlicnent force to f5 slightly spring the rods t) and l0 between their ends away from tlne rod 8, thus atording a ri id reinforcing frame Ixnsaessinng tram ua ities. The pnvotal connection of the r s t) and 10 with the rod 8 afforded by 7C tlne provision of the eyes 15, enables the frame to be collapsed and folded into con-"f dition for ease of shipment.

'llne position tlne rods occupy with relnn tionn to each other when the rods t) and l0 75 :nre turned nt their ivotal connnnectionnsn with tlne rod 8 for exten mg them tothe position they occupy in use, in-n tlunt represented inn Fig. t3, inn which poation they cnperatc ucar their op osite ends with metal plates 80 t7, can-h of which contains parallel gmovea. 18 ou its upper surface for receiving the rode` t) nnd'lU, as illustrated iu Fi 4, these plates preferably being so forme( as to nfford longitudinally extenda ribs lt) on their bottom surface@ prewentnng shoulders 20. At each end portion of tlnc reinforcin nncnnbers are braces 2l and 229 each of whic n is adjustable on the rod 8. The upper ende of the braces 2l extend into a rtm1-.8,23 90 inn the plates 17 near one end nerrof, and the up nen 4ende of the braces 22, which are formed with undercut portions 24 .mening toward tlne ends of the neinnforcing frame, extend through openings 25 inn the plates to- 95 ward their opposite ends. 'llnese brutes. which are provnded for tlne pnrlxme of al` i'ordinng rigidity to tlne struetnue annd abutnnennts for wen ge keys, as hereinafter described, inn aswnnnlnling the plates witlntlne re- "l" inferi-ing frannne, nre. ad'usted upon tlne rod 8 to a position in whit-i they rigidly him' a ainnst this rod and' forcibly beur against t ne walls of the innings in the platea into wlnictn the extent inn which nmition they l muy be he. d as by nuits 215 and 27 screwing on the rod 8.

lnn forming n tie in accordance with tlne. preferred ennnlmdinnennt of any invention, l employ two nnnolds 28 formed of sheet nnnctul, l

each of which is designed to receive the concrete for forming one of the two heads 29 of the tie. Each mold has portions of' the metal forming its opposed upper edge portions lientl inwardly to form seats 30. lt will be understood that preliminary to the moldin of the concrete for forming the heads. llie reinforcing frame with the plates 17 connected thereto as descrilwd, is positioned in the opliosed molds to extend into the latter at its opposite ends. ns clearlv illustrated in Fig. l, to canse the plates 1,7 to rest upon the seats 30 and thi` ends of the rods formin extend close. to t e ends of the molds, this frame, by reason of the seating of its rods t) and 10 in the inves 18 in the plates 17, being maintain inl suspended condition in the molds. 'llie concrete for forming the heads 20 may then he filled into the molds to incase the end-portions of the frame and the braces 2l and 22, aiid preferably extend over the edges of the plates as re iresented. The plates I7 thus exposed at tllie up ier surface of the tie form supports for wot en shims 3l, u )on which latter it is desi ied that the rails beseated cross-wise o the heads 29, and fastened to the plates in any desirable way.

The forni of means for fastening the rails to the )lates which l prefer to eniplov are those i nstrated in detail in Fig. 6. These means comprise a removable and replaceable abutment clip 32 for one side of a rail, designed to engage with its supporting plate in a uianner to resist strains exerted against it. and a second clip 33 for the other side of the rail adapted to be forced into elpee and rigid enga nient with the rail as hy wcdging means iereinafter referred to. 'llie .abutment clips :l2 are of general Boihape affording opiositely extending undercut lugs 34 and with the surfaces of the opposed cd -portions of these clips arranged in step relation as represented, whereby when t ie clip is inse d'inio an opening 3u in the plate 17 ad'a t to the o iening 23 and rests at one o its undercut ugs upon the flange of a rail, as for inxtance the flange 37 of the nil 38, or upon the flange ofa fl. iplate auch as that repieaented at 80, it will interlock with the top and bottom surfaces of thia plate, as re ruicnted of the clip illustrated in Fig. 8. crtiona of theabutment clips 82 are thus canned to extend below the platee 17 into au openlnglin tbe concrete, which may be formed the o f molding the beads 29, or .in any other suitable way. The clips 88 are each w iol-ined with a bead 40 alcrding a raile e me. ...e uw ion a ma an a eprosar t at ita lower end 'with a roun ed, n per surface' as indicated at 45 these clips adapted to be inaertell the reinforcing frame to` into openings 46 in the plates 17 and therein tui-nei to cause the cross-bars to extend transversely of the ilates. 'llie clips 33 are bodily movable ongitudlnally of the plates in the oienings 46 as through the inedinin of wedge-bars 47 en 'ng with the shouldered portions 42 ofutlicse clips and the undercut portions 24 of the braces 22, to cause the flanges 4l to be moved toward the rail and turned down and a inst those flanges of the rail, such as the anges 48, which opfpose the flanges 37. The arrangement o the step surfaces on the edges of the cli is 32 a jacent to their lugs 34 and 35 is sucli as to permit of adjustment of the rails upon the plates l itndiaally ot the tie, this bein accompli ed by inverting the clips in t e o icnin 36.

lt will be noted that w iere t e fish-plates for connecting together abutting, rails, span the ties. the rail-securing clips on the ties thus spanned overlap the flanges of the shplates which. in turn, niet u n the flanges of the abutting rails, thus tli: clips enga ing with the flsh-plates need di'er from clips adapted to engage directly with the flanges o the rails in size onl to cause their iaiLtlange-engagin slioiil ers to projeet a suflicient distance a vo the lates, the principle of operation of these ipa being identical.

While l have shown and described a particular forni of means for securin the rails to the plates 17, l do not wish to understood as liniitin my invention to the eniployment of a'uci means, as an other suitable form of rail-fasteners may employed without de rtii from the spirit of my invention. ms, or example, the faatenia means may be in the form of clips 40 an 50 bolted to the plates 17 to enga 'e with the opposite flanges of the rail as c early illusfruted iii Fig. 7.

The form of mold which I refer to ein; ploy for formin the concrete reads 29 have their outer en -portions flaring, aa represented at 5l, with inwardl extending flan s 52 along their up r rportions, the atter serving to rein orce t concrete,

and-tho flarin v rtioii of the mold alchiing to the nulli l concrete -lieads widened ends which present a broad bearing surface of the heads on tbe ballast: of the roadbed, at tlioae points where resistance to downwardly directed strains ia moat-needed. It will be understood that the ase of a inold of the character described ia not indiapenlible to the forinin of a tie embodying in iinprovenien tiugh it is highly deaira le to ein loy suc a mold.

connecting the heads 20 through the m inni of a reinforcing fraaie formed of the roda 8, 9 and 10, a d rec of flexibility is adorded to' the tie whici closely approximates tlnu, of the wooden tie.
