To ctZZ wtomt may concern/:

Be it knownfthat I, CARL F. KRES'S, Jr., of

Johnstown, in the county of Cambria and` State of Pennsylvania, have invented a new and useful Improvement in Railway-Frogs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention has relation to certain new and useful improvements in railway-frogs of that type which are constructed from a number of rails or railsections with a metal chock cast in place between the meeting or adjacent end portions of the rails.

The invention is designed to provide a frog of this type constructed from girder-rails in which the rails themselves form the entire wearing portions or surfaces of the frog, the

cast-metal chock serving to unite the rails and form a perfect support for their head portions without forming any part of the Wear-surface. It is also designedto provide a solid durable structure composed of girderrails, which can be readily built up and in which the wing rails are readily removable,

With these objects in view the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims, reference being had to the accompanying drawings, in which-n Figure l is a plan View of a fr'og constructed in accordance with my invention. Fig. 2 is a similar view `with the parts separated from eachother; and Figs. 3, 4, 5, 6, and 7 are sections on the lines 3 3, 4 4, 5 5, 6 6, and 7 7, respectively, of Fig. l.

The letters A and B designate the two point rails; C and D, the two wing rails; E, the cast-metal chock, and F the securingbolts. These rails are all girder-rails, the

, rails A and B being sidebearing tram-rails,

and the rails C and D guard-rails.

The two point-rails are each planed or cut away on their inner sides to bring their head and web portions together to form the usual point, as shown in Figs. 3 and 4. From the points e to their inner ends their tram portions are planed out, as shown at c', and their base-danger are also partially cut away (see Fig. 3) on the tram sides.

l The two wihg rails are each bent Vin the usual manner at the point c, opposite the center of the frog. From the point CZ to, a

point CZ' somewhat beyond the center of the frog the innerside of cach of these rails is cut away on a line coinciding with the lon-V gitudinal center of the-frog, this cut being madethrough both the top and foot portions of the rail, thereby gradually and finally en? tirely removing the guard portions h, a portion of the licor of the iangeway,and also the inner flange of the foot. At the point d an outward oifset is made into the, floor of the langeway, and from this offset the cut is made obliquely through said iioor to theend 4of the rail. When the rails are assembled,

the partiallyremoved guards of the wing rails iit together to form the point t', and the flangeway-iioors abut each other at the center of the structure and also t the sides of the head portions of the point-rails, the offsets at the point d making an opening lc, which forms a gate through which is poured fluid metal to formv the cast chock E. The web portions of the rails A and B are formed with openings p for the cast metal toiiow through, and thus unite them solidly together. Before pouring this metal suitable core-rods are placed in position through the rails to form openings through which in the nished structure are passed the bolts F. These bolts serve to secure the win g rails solidly but removably in place. The cast metal entirely iills the spaces between the rails at the center of the structure and forms a support for the head portions of the severed rails. It forms, however, no part of the wear-surface of the frog, its only exposed portion being where it fills the small gate-opening 7c.

It will be seen that the frog thus constructed is one of great strength, having throughout the equivalent cross-section of two rails.

Vhile I havev shown therails A and B as being side-bearing girder tram-rails, they may just as well be guardmails, in which case the cut-s made from the points a would remove theentire guard portions from these points. The rails C and D may also be tram-rails, in which case the trams would be cut in substantially the same lines as the guards in the construction shown. Hence do not wish to limit myself to the particular construction and combination which I have herein shown and described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

I. In a railway-frog,thc combination with the girder-rails abutted to form the point of the frog, and cut away at their inner end portions at their outer sides, of the girder wing rails, having a portion of their heads removed at their inner sides on lines coinciding with the longitudinal center of the frog and abutting each other, and other portions cut obliquely to abut the cut-away faces of the head portions of the point-rails,and a central chock cast to said rails, substantially as described.

2. In a railway-frog, the combination with the two girder-rails abutted at their heads to form the point of the frog, of the two girder wing rails cut away at their inner sides on two different lines, whereby the floor of their lfiangeways or grooves abut each other at the centralportion of the frog, and also abut the sides of the point-rails, together 'with a central chock cast to said rails, substantially as described.

' 3. In a railway-frog, composed of girder-` rails and a metal chock cast to said rails, the

the point-rails cut away at their inner end portions at their outer sides, of the wing rails having the floors of their fiangeways partially removed,.and 'abutted at their central portions and at their guard-forming ends having said iioors abutting the sides of the pointrails, a cast-metal chock -uniting said pointrails, and removable bolts holding the Wing rails to the chock, substantially as described.

5. In a railway-frog, the combination with the girder pointrails A and B, having portions of their heads removed at their outer sides, of the girder wing rails having the inner portions of their heads removed on a straight line from the points d to d', and on an oblique line from the point d to the guardforming end of the rail, the cast-metal chock and the removable bolts for securingthe wing rails to the said chock, substantially as described.

6. A railway-frog composed of girder-rails and a central metal chock cast to said rails, said rails having their head portions fitted and abutted to form the entire wear-surface of the frog, and the castfmetal chock filling the entire space between and underneath the abutted portions of said raiis, substantially as described.

In testimony whereof I liaveafxed my signature in presence of two witnesses.
