RAILWAYFROG.

SPECIFICATION forming part of Letters Patent N o. 639,251, dated December 19, 1899. Application iile July 22, 1899. Serial No. 724,852. (No model.)

To all whom t may concern:

Be it known that I, CARL F. KREss, J r., 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 eX- act description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates that class of frogs which are built up of rails or rail-sections properly fitted together and connected by a solid chuck cast between them and through apertures in their web portions.

The objects of my invention are to provide a frog of the class described which shall be light and durable and built up of a minimum Iof parts capable of being readily constructed, fitted, and secured together, and which by its center construction provides for an increased width of wheel-bearing.

To these ends my invention consists in the novel construction, arrangement, and combination of parts hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, Figure l is a plan view of my improved frog. Fig. 2 is a section on the line :t x of Fig. l, and Fig. 3 is a section on the line y y of Fig. 1.

A and B designate two continuous T-wing rails bent as shown.

C is a guard-rail, and D is the cast chuck.

Cut in the head of the rail B are two wheelgrooves ff', whose edges aline, respectively, with the inner lines of the head of the wing portions of the rail A and with the inner line of the head of the guard-rail C. These two grooves leave between them a triangular center or apex portion d of the rail B,whose outer .straight face is planed and fitted to the inner planed face a of the central straight portionV of the rail A, the base-anges of the rail B fitting or overlapping the inner base-flangeof the rail A at the cent-er of the frog and overlapped upon tlie opposite side by the inner base-flange of the guard-rail C, which is bent to conform to the angle of the rail B, and has a broadened central head portion c opposite the portion inthe grooveintersectionbeingformed in part in the head of the rail B and in part in the head of the guard-rail, as seen in Fig.

2. The guard-rail has apertures c through its web portions, through which extend the connecting portions of the cast chuck, which fills the space between the webs of the several rails jand underlies and supports their heads, forming a solid floor for the frog. This chuck also extends between the rails A and B to each side of the center of the frog to points preferably about coincident with 6o the ends of the guard-rail, Hoor-plates F being provided to form the bottoms and guardwalls of the wheel-groove. These plates are fitted to the webs ofthe rails A, as shown in Fig. 3, and extend, respectively, from the groovesff to the ends of the chuck D. They are formed with inclines or risers (indicated at f2) for the purpose of raising the wheeliianges in passing over the frog. Similar inclines or rising surfaces f3 are provided in the 7o wheel-grooves of the guard-rail. The several rails, together with the Hoor-plates, are further united by bolts I-I, which extend through the rails and through holes cored in the chuckcasting.

It will be readily seen that the construction described reduces toa minimum the number of parts and provides a rigid and durable structure.

The formation of the rails A and B at their 8o central portions with the triangular-head portion b abutting the head of the rail`A provides, it will be seen, a considerably-increased width of wheel-bearin g and makes a neat frog center construction. 4 8 5 I do not desire to limit myself to the exact construction which I have described, as the same may be varied in detail without departing from the spirit and scope of my invention.

Having thus described myinvention, what 9o I claim, and desire to protect by Letters Patent, is-

1. The herein-described railway-frog composed of the two wing-rails having each a straight intermediate portion abutting a similar portion of the other rail, one of said rails having both wheel-grooves formed across its head, a guard-rail bent to conform to the grooved wing-rail, and having head-grooves which aline with the grooves in the wing-rail, roo and means for securing said rails together'.

2. The herein-described railway-frog cornposed of two wing rails having abutted straight portionsintermediate their wings,one of said rails having both Wheel-grooves formed aorossits head, a bent guard-rail having headgrooves which aline with respective grooves at the wing-rail, a east-metal chuck, and movable bolts extending through the said rails and ohuek.

3. A railway-frog composed of two wingrails, having eaoh a straight portion intermediate its two Wings, one of said rails having` both Wheel-grooves formed in its head and interseoting across its straight central portion, the latter having the head portion intermediate said grooves formed with a straight faee which abuts the similar face of the intermediate portion of the other rail, the bent guardrail, the east chuck filling the spaces between the wing and guard rails and cast through the perforations of one of the Wing-rails, and the bolts extending througlrthe rail-webs and east chuck.

4. The herein-described railway-frog cornprising the bent wing-rails A and B, having laterally-abutted intermediate portions, one of which has both Wheel-grooves of the frog out across its head, the bent guard-rail, the east ehnek, and the floor-plates between said ohnek and the rail A.

5. The herein-described railway-frog oomprising the laterally-abutted main rails, one of which has both the Wheel-grooves intersecting across the head, the bent guard-rail having` the risers, the intermediate east chuck, and the door and guard plates intermediate the ohuel; and the wing portions of the main rail on the opposite side from the guard-rail.

In testimony whereof I have affixed my signature in presence of two Witnesses.

CARL F. KRESS, JR.
