RAILNAY-FROG.

Bo it known that I, Jon E. GRAHAM, a citizen of the U nil rd. States, residing at Salem, in the county p Ronni oke and State of Virginia, helye invented a newand'nseiul .Rnilwny-Frog, 01 which the following is specification. I

This in vention relates to rziilwayirogs.

The objects of the invention are to simplify the con struction and increase the efficiency 01 such devices, to

dispense with the employment of guard-rails opp 'isi'te the frog-point, to prevent springing or displacement of the frog-rails which ordinarily results from the side thrust and pressure of the engine and cor wheels, to ret-gtin the frog-rails within the irog even in case of breakage of the former, to reduce the side thrust of the wheels against the llO -llElTlg(S, to prevent the wheel-flange from striking the frogpoint, to compensate for any wear of the frog-flanges which would reduce the cfliciency oi the device, toprocludc any deflection of the frog-point relatively to the frog, nnd linslly, generally to improve and strengthen device of this character.

With the above and other objects in view, as will appear as the nature of the invention i s better understood, the sanle consists in the novel construction and comhi' nation of parts" a railway-frog, 215 will he hereinafter fully descrihed and claimed.

In the accompanying drawings, forming a part of this specification, and in which the characters of reference indicate corresponding parts, there is illustrated one form of CFQlHXlllnQflil oi the invention capable oi corrying the saine into practical operation, it heing under-- stood that the elements therein exhibited may he varied or changed as to shape. proportion, and exact manner (xf nsseiiiblage without departing from the spirit thereof, and in these dra rings- Figure 1 isa view in plan, exhibiting a frog constructed in accordance with the present invention; Fig. 2 is view in elevation, partiy in section, showing the cooperative relation between the frog-mils, frog, and a carwheel when the latter is traveling over the ports; Fig. 3 is a perspective detail vicwof thc frog with its parts separated, Fig. 4 is a sectional dot-nil View of a slightly- .nioditicd form oi the invention.

Referring to the drawings, 1 and 2 designate a pair of frog-rails, and 3 a irog-p0int. These parts may he of the usual or 'any preferred construction, and thcrrlhrc need no detailed dcscrip tion.

The present invention resides in the novel construu tion of the frog proper, the same being shown in detail in Fig. 8 and comprising two frog-blocks -l and 5, and. a spacing-block 6. Eocirof the frog-blocks is a counterpart of the other, and a. description of one Will tlnzreiorc svrvc for both. The block may be either rolled or cast, as may he preferred, and is provid ed on. its lower outer specification of Beissusd Letters Patent.

side with a base-flange T, at its upper outer sidewith. wheel-flange 8, on its inner side with a rail-tread seat 9,

and adjacent to the wheel-flange with a wheel-rim tread 16. The block is formed on proper lines and curves to cause the wheels to be switched irom one t1 ack to another in the usnai manner and generally conforms to the lines of an ordinary frog. When the two irog-blocks are assembled, as shown in Fig. 1, the wheelflonges converge toward each other in the direction of the frog-point,-tl1ereby causing the entering end 01' the frog to present on incline l ov'i A ge face to the side of the car or engine wheels, which will operate to shiflrthe samegradnally'and smoothiy onto the 1-og-point,ji:he

entering ends of the w reel-flanges being slightly curved away from. the frog-rails, thus to prevent. any impact between the sides of the wheels and the flanges on the 7 0 initial entry of the former into the frog. Oi course, it will be understood that the opposed faces of the two frog-blocks are oppositely curved, thus to secure the proper shifting of the car-wheels from one of the frograils to the other on either side.

The spacing-block 6 is preferably shaped to conform accurately to the opposed faces 11 and 12 of the frogblocks, and the three parts are held combined by bolts 13, in this instance three in number, which pass through the ,body portions of the frog-blocks and of the spacingblock, suitable bolt-0penings 14 being provided for this purpose.

As shown in Fig. 2, the under side of the frog members closely impinge and inclosc the bases 15 of the frog-rails, and to secure this result the under face of the spiicinghlock is angnlarly or revcrsely inclined, as shown at 16, to [it against the upper sides of the inner portions of the bases, while the under face of each of the frog-blocks is upwardly inclined, as at l7 to bee upon the upper faces of the outer porticms of the bases. in providing the inclined pmrtions l7 there is iorlned a longitudinal shoulder l8 on the outer side oi each of the blocks, and these shoulders bear against the outer edges of the bases and operatic positivciy to chimp them together and to hold thorn from niovenian t while the spacing-block also cooperates Lu pr any in word increment of the frog-rails ielstiveiy to each other.

In order to prevent any lateral shitthig of the frogpoint 3, one end oi the spacing-lolockls provided with a 1D! triangular vertically-disposed,grooye or recess 19, in which the tcrniinn-l oi the frog-point rests, as clearly shown in Fig. l.

As shown in Figs. l-zunl 2, the whecla'iin treads incline slightly toward t'm' ccnter oi the frog, hihthe' ltlf upper laces oi the frog-mil trends are horizontal; 1 t, as shown in Fig.4, both the wheel-rim treads and the upper feces of nit lrog rails may be inclined, thus con- To increase the liie oi the frog and to compensate for wear of the flanges 8, liners or tillers 20 may he eniployed, which will be disposed between theinner faces block when its flange'heeomes worn is rendered unneeessary, therehy effecting large saving to railway rompanics. 4

It will he seen [mm the foregoing description that hy the provision ol' the wheel-flanges 8 on the frog-blocks the empli'iynient of the ordinary guard-rails is rendered unnecessary and that these wheel-flanges, or rather guanhfianges, will operate positively to cause the rarwheels to he shil'ted from one o[ the frog-rails to the other. lly reasonol' the rail-trind seats 9 a solid hearing is provided for the uuderiates or the frog-rail treads, and, further, these are eaused to present, in combination with the \vheela'im treads l0 a, praetieally flat surface OV'LTI which the wheels will travel. Owing to the manner in which all the parts are eonstructed and eomhined there will he no possibility of a frog-rail heeoining separated from the frog proper; nor for the same to take place with Llliyllogjhdlll; so long as the bolts 13, which pass through fthe [rog- |)lli(l\'S, frog-rails and spacing-him. remain in position. I

By eonstrueting the trog-hloeks and spacing-block in the i'nanner deserihi-d these parts may he combined with rails in common use without requiring an y change. in their structural arrangement, thereby adapting the d eviee for ready adoption when desired Having thus desd-rihed my invention, what I claim l as new and desire to secure by Letters Patent is:
