` To all .whom it may concern:

Be it known that I, JAMESE. LEWIS, a citi- Zen of the United' States, residing at Steell ton, in the county of Dauphin, State of Penn'- 5 Sylvania, have invented certain new and use-` y ro Figure 1 is a p an view. Fig.l 2 is asection ``online 2 2, Fig. 1 Fig. 3 is a section on line 3 3, Fig. 1.` Fig. 4 is a section on line 4 4,

Fig. 1.

Tins invention reinas/tn that kind f mit '15 road-frogs in which a hard-metal bearing-l pielce is inserted on the inner side of the wingrai s.

The primary object of the invention is to provide` a fro of the kind in which Said in'- zo sert-piece sha1 be lcomparatively of consid#` erable length and `width and firmly held against longitudinal as well as lateral displacement. l Another object oi the invention is to pro- 2 5 -vide such a frog in which guttered carwheels vpassing thereover will not wear a groove in the surface of the wing-rail, as is the case with i'rogs of the ordinaryconstr'uction.

" 3o The lexact nature of the invention will appear from the following description.

y In the' drawings, 1 1 are the wing-rails; 2, the point of the frog; 8, the usual intervening 'iilling-pieces 44, the two track-rails converg- `3,5l ing to form the point, and 5 the two convergin track-rails converging at the opposite oriIIeel end of the Jfrog.

In carrying out my invention I cutaway the inner side oi each oi the wing-rails from a 4o point 6, Fig. 1, some distance back of the end oi the frog-point to the end of the said wing rails in advance of the frog-point, the ends of the vwing-rails to the rear of the frog-point being bent outwardly, as seen in Fig. 1, in the 4'5 usual way. I insert in the space formed by cutting away the side of the wing-rail ahardmetal bearing-piece 7, one endof which abuts against the shoulder 6, Jformed by the cutting away of the wing-rail. I also make in the inner side of the opposite end portion ofeach of the bearing-pieces an oiiset 8, having a shoulder 9 for the reception of the ends ofthe rails 5, respectively. The heads of these ends of the rails 5 are beveled, as seen in Fig. 1, so that their inner sides are in line with the inner sides of the bearing-pieces, respectively, which latterare in line with the inner sides of the respective wing-rails beyond the Shoulders 6. The rails 5 would ordinarily be separated by a iillingblock 10, so as to leave the necessary space between the ends of said rails for the passage oi the car-wheel iiange. The bottoms of said bearing-pieces 7 rest upon 'the top oi the Jfeet of the wing-rails and their outer sides against the .cut-away heads and the webs of said wing-rails, respectively, all as seen in Fig. 3. v

. In the. present instance for a purpose hereinafter explained the upper surface oi' each of the insert-pieces 6 are inclined from the heel towardthe point of the frog', beginning at the free end of said pieces 7 in a plane slightly below the level of the rails 5, as indicated by dotted lines in Fig; 2, thence gradually rising t0 a `plane above that of the frog-point and then just Abeyond the iront end of the latter descending gradually to the level of the point, as shown by full lines in Fig. 2. Ther 3. The object of making the insert bearingpieces extend above the level of the end of thev frog-point and then gradually descend to Isuch levelis to preserve said point from the wear or breaking down ,of the narrow end'thereoi, which would be liable to occur if the carwheels were permitted to come against said end when a train ispassing through said frog in a `direction toward said point. f

The wing-rails, insert bearing-pieces, iillingfpieces, frog-point, andthe rails-4 and 5 are firmly bound together by means of through-bolts 11.

It willl be seen by the construction described that there is a comparatively long and wide body of hard-metal insert extending forward and rearward oi the extreme end of the rog -.point, and these insert bearingpieces are iirmly held in place against longiroo ther, as is well known, after the wheels of cars have run for some time upon railroads said wheels become guttered--that 1s, a more or IOS less shallow groove becomes worn in the tread ofthe wheel, thus forming a false flange on the outer portion of the periphery of the wheel. This flange' is narrow, and consequently in the usual construction of frogs (in which the wing-rails and track-rails 5 are integral) as a wheel passes over a wing-rail toward the point ofthe frog the said false flange in time cuts or wears an oblique objection? able groove in the top of the wing-rail. With my construction the car-Wheel advancing toward the frog-point is, so to say, picked up. by the insertpieces 7 as it (the wheel) comes opposite the heel ortion of the frog by the said false ange riding upon the insertpiece. The periphery of the wheel riding upon said insert-piece and passing obliquely across the said insert-piece on the way to the frog-point does not wear a groove in said insert-piece, because the latter is of very hard metal-much harder than that of the usual wing-rails.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl'. In a railroad-frog, the combinationof the frog-point, the wing-rails having the inner sides of their heads cut away from a point back of the frog-point to the forward end of said rails, the hard-metal bearing-pieces inserted in the space formed by cutting away said rail-heads and having the lateral offsets at their free ends, and the track-rails having the beveled ends fitted to said offsets, the in' ner side of each of said wing-rails, bearingpieces and beveledy end of said track-rai s forming a continuous gage-line, substantially as and for the pur ose set forth.

2. In a railroa -frog, the combination of the frog-point, the wing-rails, having the inner Sides of their heads cut away from a point back of said frog-point, to the forward end of said rails, the hard-metal bearing-pieces inserted in the space formed by cutting away said rail-heads, and having the lateral offsets at their free ends, the track-rails having the beveled ends fitted to said offsets; the inner side of said wing-rails to the rear of'said bearing-pieces, the inner side of the latter, and

the inner side of the beveled end of said track- JAMES E. LEWIS.
