Be it known that we, JOHN A. Rosanne, of Trenton, in the county of Mercer, und Stute ofl New Jersey,

and JOHN MeMURTRY, of Lexington, in the county oi Fayette, and State of Kentucky, have invented a' newl and improved Railroad Choir; and we do hereby declare that the fellowingis-a full, clear, and exact descrip.- tion thereof, which will enable others skilled in the art. to make and use the same, reference being` had to the accompanying drawings, forming part of this specification, similar letters of referenectheren indicating likepurts. l

The object of this invention is. to obtain a chair for connecting the ends ol' railroad rails in such a intmer that they will be held firmly in position,and bia-protected from the action of the cur-wheels, and prevented from being hammered down und 'flattened as thel wlic'elsvpass over them, and .woin out betale the remainder of' the rails, a contingency due mainly to the working of the ends of the rails vcrlically-underthcweight of thecars,

and which is attended with great expense in the way of rcrolling or repairing' the rails 4find makingjgoo'd the i increased wear of machinery and Arollingr stock. 'In the accompanying drawings- No'. 1 in 'Figure l. represents a transverse vert-ical section of therst modification of our invention. lwhich will be ilrst described.

A A represents s longitudinal -'section of u'sleepor or cross-tic, v"and -the remainder of thel ligure a. trans- .verse vertical l.section of the rail, the chair, andthe lower lportionpt" n cnr-wheel, Blheing vthe Aruil and D the car-wheel. Gis a solid hlockof cast iron or st eeL-or, 'other'equirsleutl material-. This block is made long' 'enough 'to rest on two sleepers,or cross-ties, and may belinda' of suilicient length to' rest on three ormore, if

it is thought desirable. The side of the block .whieli is next to the'railsis cast o fn curved form corresponding with the curvature ofthe side of. -the rail's, so 'that the twomay be adjusted closely or snugly to each other. The upper surface of the block is ou allev'elwith or slightly above thduppor surface of the rails, so that the car-wheels, (the rim ortread of which, in llordin'nrywheels, i's'do'uble the" width ofthe head of therails, and, 1in the driving-wheels of locomotives, wider-still ihpassingalong thei'rdils, 'will cause the ex'tra width of the wheels to roll over and bear upon the, upper surfscefof .the `lilockQ-which should bcmadeof equal strength with the rails-themselves. E representada-plete'ofwrouht or rolled iron or'stecl, or other equivalentmaterinl, wheh'is wrought or r'olled so as V to be dfa ctirved 'form on 'one side, mirresponding with the curvature of the side of the rails, against which it is snugly iitted entire side opposite to'tho block C. 'l'hore are four bolts 7i, which' pass transversely throughv the plate E, thc rail B, .and the block C, and bind them lirmly together, the

. holes through the rails to. admit said bolts being elongated, so as to allowfor lthe expansion und contraction of 'the metal in the rails and choir resulting fromchanges of temperature. Tha Arails are fastened to the crossties in the usual manner, by spikes i, And the block C is kept in position held to the cross-'ties by u. hor

or slab of hard wood, K, of equal. lengthwith-or longer than the block lagain-etzwhieh it is ltted` und which is firmly spiked to the .two cross-tiesouwhich the i;loclrrestsl-v The-upper surface .of thel bleek C,when the sanie is n nade of cast ironyip cust'with achillto resist-wear. v. l

No. 2 in iig.' 1 represents the second modicaton of our-invention, und only diL-rs from No. 1 in the same figure inthe form of' the lower 'partefr the hloelc C, and in the manner in which it is fastened to the sleepers or cross-ties. The blocki-G, in this moditicationyhns a bose, f, which extendsits whole length, and is itted into vrecesses or grooves out 'across the-sleepers on which tho-block' rests, the -lower surface of the hase f being the bearing surface ofthe b leclr. The-busefin thisl modiention'-nilswers `the same purpose as the tlanges gg, shown inNo. 2, Figure 8, lwhi'ehgrll be hereafter described. And the block C in this modification, as well as that-shown nt No. 8, tigiil, is spikedtothe sleepers or cro'ssfties with "the ordinary railroad spikes, insteodl'of being fastened by a slab 'of wood. i No. 8 in iig. 1 represents the third,modification of our invention, vand 'only di'ess from No. 2 in the same ligure inl the fact that the bns'ej of the'liloclrl'is cast of a width suillcicnt to.extend under and support the rails B, which rest upon it. Thil'bse, es well ns that vin the second modification, is fitted into recesses or grooves cut across the sleepermand'nnsvrcrs the ,purpose of t-he flanges g g, shown in No. 2, tig. -3.

. Figure-2 is a side view` or elevation, freni the outside of the track,y of the modifications ksho-wn at No. 2 undV No.3ing.1.4

A A. are transverse sections of the two sleepers or cross-ties on which the chair rests; B B are the rails; C C is the castiron block, indicated by the samelette'r in fig. 1; f is the base,.fitted into recesses or grooves cut across the sleepers; h h are the-bolts aude' the spikes.' There. are projectionjjver thesleepers at each end of the outside of the block CC, which are notched to receive the spikes, and thereby hold the bleek niore securely in its position.4 The joint. formed bythe railsB B is at or near the ini'ddle of. the block C C, as. lshownlbythe vertical broken lines in the ligure. The upper surface of the block should be sulliciently high, when compared 'with the upper surface of the rails, toreeeive the full weight of the cars when passing over it, 4.but not so high as to-produee a jar when the wheelspas's on to the block. The difference shown in the figure between the height o'f the iipper surface of the block C C and of the rails B B is'. owing to the fact that the height of"the block is graduated ,tothe bevel of the rim ol' the car-wheels, the tread of whicln'nt their outer edge, is higher than next the flange, as shown in g. L To guard against rthe jai-which would take place it" the block C C should be slightly tooihigh, when compared with the rails, there is a curved depression at each end of the upper surfaee'of the bloek, asshown in the drawing, but no great inequality of height between the block and the rails )vonldhe allowable. 4Itwill thus be seen vthat, in our improvement, when the car-wheels pass over the ends er joints of the rails, the weight of the cars Vwill be supported by the block C C. the wheels rolling over and bearing upon the upper surface of said block, and that the ends of the rails will thereby be protected from being hammered and Worrncut by the ear-wheels. I i

4The only chaiige required n'flg. 2, to-rnake it correctly representthe side View or elevation Jt" thc modification shown at No. l in iig. 1'woulrl be to omit the base f, the projectionsjj, and th'e'spikes iz', ,and to indicate Yon then drawing the slab ofrwood K.' 4 v f v In casting the block C C it may be found in practice that tocore it on the outeror inner surface, or both, betweeny the bolt-holes, willmake a better casting, withoutdiminishing its strength, and the weight-of n letal in the bloek/ will thereby be reduced. i e i V Y No.''and`No. 2, in iig. 3e represent the lonrth and fifth modifications oi'l our invention. Thef di'er fromY the three former modifications mainly in the fact that C C, instendA of being castron blocks, represent, inig., 3, plates niadeof rolled or wrought iron o r steel, or other equivalent materih'l, of equal strengthlwith the nil.- and long enough to rest on two or more sleepers-or cross-ties, the vupper surface, of saidl plates beingon level with or slightly above the upper surface of .the rails,'so that theextra. width of the car-wheels will rollover and `bem-.Wen said plates as the whels poss along the rails. The' side of' the' plate C nextthe 'rails is .rolled l with curved surfaces,`to fit thehead and'base of the rails, but alphollow space is left oppg'isitefthel central-,or mostV depressed part of the. rails, to fill which would onlyadd to the Aweight of the platewithont materially increasingr its strength. i i i; i Y' n frneplate C, inlNo. 1, 3, isrolled ,with a base,f, of equal length with theplntepnnd of' a width sucient to extend under and support `the rails B. In the same modification there is also n. plate, 'Ef of wrought.. or rolled iron o1" steel,` or. other equivalent material, which is rolled with a-curved surface, to it the side o the rails opposite the plate'G. The two plates and the rails are firmly bolted together by four boltl'7i, as in the modifications previously described. And the plate is spiked to the sleepers or cross-ties by vthespilies 1,'

The, plate C, in ,No.VZ-igJS, isrolled with a basehf, of equallength with thejplate, but only wide enough e to extend under one-half of the bottom of the rails B. .The plate E in this modification is rundev of wrought y orrolled iron oristeeh'orother equivalent material, and is rolled with a curved surface, corresponding with the i curvature of the side ofthe rails, and 1s adjusted snuglythereto-on the side opposite the. pluteC. Theplate E' is valso'r'olled withabasgf, of equal length withthe platetand of suicient width to extend under one-half of thel bottom of the' rails. On the inner edges of the basff of each of these' two Vplates .there erover-tical or pendent flanges g g, which-together lit into recesses or f roove#` cutliacross the sleeper'sion which the plates rest. "When the plates Gand E are iny their proper position, thevz'ails between them, the anges g gi will abut closely against the'opposite sides of the recesses or grooves in the lsleeper-si. but there is space` enough left between the flanges theinselves to allow ol' the plates being plncedfin position or, removed without inconvenienee from the flanges fitting too tightly in the grooves. Therplates and rails `are bolted together, and the plates spiked to the cross-ties, in this modification', as in those proviouslyidescribed'.

The flanges g g of the plates Gand E eli'ectua'lly prevent any lateralvniovemont of the chair. And it will hr. observed that, 4from that fact, and by reason of the'cnr-,wheels rolling upon fthe .upper surface of the plate C, andfrom the general construction and strength of the chair, nearljall the strain 'caused by the passage of trains is withdrawn' from the boltsh,'while in what ale'kuownA ai fish-bar joints'the entire Intl-ain comes upon the bolts, thereby loosening them and rendering the joints inei'lieient.A 4 .y A y Figure. Ai'rprssents a sideview or elevation, from the outside ofthe track, Voi'- the modification. shown in No. 2 of fig. 3, like parts being indicated by similar lettere o1 reference; oinrittingfthe angeg from the drawing it will' represent a like elevation of the modification shownl in Nolfloffg, The upper surface of the plate C C'hasy'acurved depression at each end, similar te, though .notuso greatrns, that of the block` C C in g.,.2. The depressions of'the latter are made in the casting, while those oi' the .former muy be niade hy pplyingthe plate, for a. few minutes, to the grindston'e. The elevations in digs. 2 'nd-4 so far resemble each otherns vto render any'further explanation of the latter unnecessary.A ButJbere is onevaluable feature of our improvement which deserves to be mentioned, namely', that it maybe applied to rails the. -ends of whit-hiero a ready'partially worn, which will obviate the necessity of rerolling or monding them. l l
