To all whom it may concern:

EDWARD W HARDEN, and MICHAEL DEMPsEY, citizens of the United States, re-

siding at Hamilton, infthe-county of Butler and State of Ohio, have invented certain new and useful Improvements in Railway-Frogs,

of which the following isaspeciflcation.

It is the object ofour invention to provide a new and im roved railwayfrog in'which: the arts whic would benormallysubjected to t e greatest wear from side-contact as well as pounding blows from the wheels of the vehicle passing thereover, shall becomposed of hard metal, for instance, hardened steel,

and so arranged that the continuity of the" tracks shall not be interfered with and so.

connected with the regular trackage that danger of derangement is avoided, and an improved construction provided, and it is the further object of our invention to so combine and arrange theconstruction mentioned that the j ointsin the frog-and preferably alsobetween the frog andthe continuation'of the trackagemay be protected from pounding stress; and theinvention will be readily understood from the following description and claims, and from the drawings, in which latter: I

vFigure '1 is a plan viewof our improved rallway frog. Flg. 2 isa vertical cross-section of the same on the line zz'of Fig. 1. Fig. 3 isa verticalcross-section of the same on the line yy of Fig. 1. Fig. 4-. is a verti-- cal cross-section ofthe same on the line 00-41:

of Fig. 1; and, Fig. 5 is a vertical cross-section of the same on theline w w of Fig. 1. j

A B O D represent stub-rails as part of the frog, between the inner ends 0f which'thei block E of the frog is located. This block,

' isof hard metal, for instance, hardened steel,

and for convenience we shall hereinafter refer to the sameas the hard-block. Ordinary continuation-rails]? GHQI of the'trackage are arranged to abut and be secured to the outer ends of the stub-rails, the outer ends of the said continuationrails being shown broken away. i

K and L are reinforce-rails at the outer portionsof the frog and in the form shown also act as riser-rails at thetoe endof the frog as shown at k 'l, and as wing or guard rails at the heel-end of the frog as shown at through the same.

j I g I I I jecting opposite the point, as shown at n, Be 1t known that we, WILLIAM H. RABBE,"

shown beveled," so thatthe joints p p may be i at an angle to the rotary axes of the wheels passing thereover. Bolts 10 pass through the parts. i '3 The point-part'of the hard-block is preferably spearesha ed, comprising the head Q and the shank ig, which latter at its outer or heel-end is formed with a riser-face g, the

rest of the spear-sha ed point-part however being preferably of the height of the rails so that the wheels may ride thereon and be su ported thereby. The inner ends of the stu rails A- B are shown beveled at their inner faces'asat a b, the shank also forming afillingblock between said stub-rails. Bolts 20 pass The hard-block as shown also comprises outer walls n 11?, shown as continuations of the sidegage-faces N N, between which and the toe the grooves R R for accommodating the flanges of the Wheels are located. The reinforce-rails are at their in ner faces provided with tapering recesses k Z for accommodating the side walls n n of I the hard-block, the hard-block adjacent said side walls also formin a filling block between said reinforce-rails, olts 30 securin the arts together. At the toe-end of said ardblock the reinforce-rails are respectively provided with slight curves k Z which, being slight and long, may be formed without drawing the temper from the rails, and at the heel-end of said hard-block they are provided with a spreading bend 76* Z for forming the wings 76 Z or-guard-rails, it being understood that these reinforce-rails at their heel-ends do not serve as supporting rails for the wheels but as guard-rails acting sidewardly against the flanges of the Wheels for directing said flangesproperly intothe grooves R R.

"Filling b o'cks S S are located between the Wing-ends of said reinforce-rails and the heel of said hard-block preferably s anning the joints a 1) between said hard-b ock and the stub-rails A B, bolts 40 holding the parts in place.

It will be noted that in our improved construction we provide a hardened wheel-supporting block against which the ends of the parted to them in manufacture which is destroyed upon the heating of the rails for the purpose of so bending the same. We avoid this objection in our improved construction and further provide a frog in which the joints are protected by riser-rails, and in our im proved construction we further protect the joints between the toe-ends of the stub-rails of the frog and the continuation-rails of the trackage joining therewith, by a combined riser and reinforce-rail, providing an especially strong and safe construction.

It will be understood that the riser portions of our improved frog act upon the outer portions of the treads of the wheels which are usually in practice of slightly greater diameter than those portions of the treads adjacent to the flanges of said wheels, owing to the wear which in practice takes place upon railway Wheels adjacent to said flanges occasioned by ridin on the regular trackage of the railway. Filling-blocks S S are shown between the rails C K and the rails D L.

It is of course obvious that changes may be made from the construction herein shown and described without departing from the spirit or scope of our invention.

Having thus fully described our invention what we claim as new and desire to secure by Letters Patent is:

1. A railway frog comprising a hard-block having a point thereon and a combined riser, reinforce and guard-rail at the side thereof said last-named rail having a downwardly sloping riser-face at its riser-end.

2. A railway frog comprising a hard-block provided with a point and opposing gagefaces adjacent thereto and a reinforce-rail at each side of said hard-block constructed as a riser-rail at its toe-end and as a wing-rail at its heel-end, each of said reinforce-rails having a downwardly sloping riser-face at its riser-end.

3. In combination, in a railway frog, a hard-block having a point and gage-face walls thereon, said gage-face walls extending beyond said point past the point of greatest convergence between said gage-face walls at the throat of said block, rails whose inner ends abut against said gage-face walls, and reinforce-rails spanning the oint between said first-named rails and gage-face walls, substantially as described.
