T0 a/ZZ wtmlt it 'may concern,.-

Be it known that i, VAL'rnr. F. GARR, residing' in Milwaukee. in the county of Miln waulee and State of 'Visconsin. have invented new and useful improvements in Railway- Frogs, of which the 'following is a description. reference being' had to the accompanying drawings, which are a part of this speciication.

This invention relates to railwapirogs designed to prevent the jar to cars in passing' a railway-crossing.

The ilange construction of railway car wheels makes it necessary that in railwaycrossings each rail should be split or contain a groove across its head to permit of the 'flanges ot' the wheels on the other track passing' therethrough. lVithout means provided ior the contrary. this opening in the bearing-surface et' each rail-head causes the wheel traveling on the rail to pound against the tar side ot' the opening` which pounding' soon results in the destruction oi' the railway-fro z The most eliicicnt method in general use Vfor avoiding this pounding and its resulting destruction of the railway-'frog is to provide inclines or risers for each track in the path of the .vheel-lianges, which by reason et' the said [ianges riding thereon litt lhe wheel slightly, so as to transfer its bearing from the tread to the hange, and then these inclines or risers of the intersecting tracks cross each other on the same horizontal plane and iin-ally decline on the other side ot' the intersection, so that the carwheels are lowered and returned to their nor mal bearing with their treads on the heads of the rails. By this means the wheels of each track have a continuous bearing-surface with their treads held up out ot' engagement with the rail-heads containing the openings, and consequently there is no pounding and the lite ot' the railway-'frog is proloi-iged. As the railway-frog is by its very nature subjected to excessive wear and liability to derangement by constituting a common part for the intersecting; tracks and because of the dilliculties in firmly securing in position its comparatively delicate and inaccessible parts. it is notoriously one ot the most vulnerable parts of railway l construction and as at present constructed is the source of many accidents.

The railway-frog constructions by which the continuous bearing-surface for the car-wheels is preserved in the manner above mentioned usually involve numerous complicated parts which are required to be littcd and connected together and to the rail-sections; and is the object oi" the present invention to sinpliliy and materially improve upon such cc, .struc-- tions by providing an integral frog t for attachment to the intersecting rails and pcssessing nearly all ot" the necessary 'tentures to produce the desired results v-:ithout the liability ot' parts becoming loose.

A particular object ot' this invention is to provide a railway-frog in which one ot the rails is left intact and constitutes what is liuc wn asa through-rail, while the intersecting rail divided and mitered or scarted at its ends to lit against the through-raih hoth rails having their heads groovcd for the passage et the iianges oiE the crm-wheels and all parts beu ing rigidly bound together by means ot' ang-ld plates iitting st the webs ot the intersecting' rails and constituting integral r` and guards therefor. with chock-bloc within the crotehes ol the intersecting rai '1.

Ff ith the above and other objects in view the invention consists in the device7 its parts,y and combinations ol" parts, as herein set fortln and their equivalents.

Referring to the accompanying drawings, in which like characters oi referenceindicate the same parts in the several views, Figure l is a plan view o' a railway-frog constructed in accordance with this invention. Fig. 2 is a plan view otono otl the angle-plates Yforming a part thereof. Fig. 3 is a side elevation oi said angle-plate. e is a transverse sectional view ot' the railway-frog, taken ou the line e #L of Fig. l. Fig. is a similar view taken on the line 5 or Fig. L and e is also a similar View taken on the line t3 t3 ot 1g. i.

in the drawings, 'Y represents one of the rails of a railway-crossing` which is lett intact and constitutes the through-rail, and 8 and 9. respccti..'ely.l regresent the two adyacent ends of the intcrsectii'ig rail. rlie ends olf' the sections and l) ot' the intersecting' rail are init/ered to the angle olwinterseigition ol the crossing' with their sectional contour such that tl1e \Y c iactlfyY lit against the irregular sides ol' the through-ruil L and conseipiontliv hear full against said through-rail throughout their end surface pair ot' angle-plates are provided to lit against the opposite sides ot the ruil intersection, und sind angle-plates are ijiracticallv identical, except that the),v are inade in reverse, so thut when applied to the opposite sides eiE the rail intersection the several partsof each stand directly opposite their counterparts ol 'the other, Each angle-plate comprises e, inain vertical portion ith which is shuped to the angle ot' the crossing' end is adapted to [it :re secting' rails bet veen their head and foot flanges in :i manner similar to :i fish-plate, the hearing-surlhce 'thereof being' providi-)d with peir oi parallel spaced 'lnng'es or heads ll to leave a clearsnce-spuce between the webs ol the rails and the upright portion l0. Une eld ol the angle-plate has e laterallv-extending' besriiig-surface 12 which is inclined from its extremity to a point und wajv thereo i", where itcontinues on a horizontal plane,and this b nu in'-.-'nn""ace cer. itutes the ri,L upon which the ilsnge ot the cnr-wheel rites to lift it and remove its trend roin the heed oit' the tract:- rail. At the outside edge of the l)e;u'iiig-sLii'- Vtace Yl2 is en upstandi n 717iange vi3, forming a ,guard ior the il; g'e oi the car-wiieel and causing the riser 12 to lie in e groove between the guard-lienge and the head ol the rail, the zuiproach to seid groove being;l Hering' by reason ot the end ol the guardllung'e 13 beine' tai'iering' ut M.

all ot' the associated parts of the frog ere bound together by bolts QLwhieh pass through the choclvbloelisq the webs olE the intersecting rails, the upright portions l() et the engl-epiates, and the lugs 20, the latter having' their outer sui-feces so slieped that the heads and nuts ot' the bolts 2l tit thereagsinst. T he choclebloek 1T is further secured in position by a bolt Q2 passing throue'h it and the webs ot' the intersecting rails. ,in this manner all of the parts are (nest rigg'idltv secured together, und erich hears upon and supports the others against the possibility of slipping out of their respective positions.

As the tread of the car-whee s may extend beyond the outer edge of the rail-head, each guard-hanne i3 is 'cut away at its inner end wl'iere it bears against the head et' the intersecting' rail to forni :i rounded wey 23, in which the edge ot' the wheel-tread may poss 'ithout engaging; the guard-flange.

Freni the foregoing' it will be seen that e railway-frog constructed in nceordunce r'ith this invention is adapted to receive the tlange of a csr-wheel zuj proaching it on either traclrailrf the iiange et the ear-wheel passing' onto the riser 12, guided thereto by 'oceans et the tapering edge i4 of the guard-flange 13 and riding' up the inclined portion of said riser to liit the tread of the csr-wheel 'from engagement with the head of the rail. "lhe cnr-whee then passes over the intersecting' rail upon its flange, which rides on the continuous su rtaces ot the riser, the bottoni portion ot' the groove l5 or lo, as the case ina); loe.l and the chockblock 1i', on which it is lowered by traveling down the declining surface et' said chochblockY until the tread again beers on the heed olf the rail.

The upright portion l05 the riser 2, und the guard-flange 13 being mede integral, there no possibility et' their becoming loose 'troni each other., and the two ongle-plates forrning' opposite sides of the'lirog with the other parts clamped therebetween by ineens et bolts Q1 passing entirely throur i the frog from one angle-plate to the other produces a most rigid structure, thoroug; lily bre-ced and supported at every point and not liable to hccorne loose or have its parts slipped from position, so that the mest desired objects for a railway-frog of this type are accomplished thereby.

Itis obvious that the railway-frog embodying this invention is not necessarily constructed ofthe form of rail shown, but that other forms of rails may be equally well adopted in its construction.

W'hile the frog member is herein termed an ,i

angle-plate, it 1s obvlous that 1t may and preferably does constitute a casting.
