RAILWAY-FROG.

SPECIFICATION forming part of Letters Patent No. 411,86*?, dated October l, 1889.

I Application ledApi-il 22, 1889. Serial No. 308,118. (No model.)

To @ZZ whom it may concern,.-

le it known that I, 1WALTER C. MEEKER, a citizen of the United States, residing at .Iersoy City, Iludson county, New Jersey, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a spcoiication.

My invention relates to that class of railroad-frogs commonly known as spring-rail or main-line7 frogs; and it consists of the novel construction and combination of parts hereinafter fully described and shown.

As is well known, thc object of a springrail frog is to give practically an unbroken track for the main line, and this is accomplished by having one of the wing-rails of the frog movable and lying close against the point of the frog and held in position by means of a spring. In order to allow the said wing-rail to lie closely to the point of the frog, it has heretofore been necessary to remove that portion ot' the flange of said wing on the side next the point. The removal of said flange necessarily weakens the said wing-rail, and thus frequently causes them to break. This breakage of the wings has been 4the serious objection to the vuse of spring-rail frogs; but the frog herein described is provided with a spring-rail, which lies close against the point of the frog, but none of the flange is removed. Hence the norinal strength of the rail remains and the liability of breakage is obviated. I attain this by the peculiar construction illustrated in the accompanying drawings, in which Figure l is a perspective view of a frog as constructed in accordance with my invention with a bed-plate. Fig. 2 is a perspcc showing liangc turned up. Fig.' 3 is a crosssection taken on the line :o c of Fig. l. Fig. 4t is a side view of the outer side of the springrail, showing more distinctly the offset.

Similarlctters referto similar parts throughout the several views.

A A are the rails forming the point of the frog. B is the stationary wing-rail. These parts are riveted to a bed-plate D `in the forni of construction shown in the drawings, Fig. 1, although they may be held togetherin any other suitable manner and the bed-plate dis pensed with.

C is the movable or spring rail.

E E E are raising-plates.

The point-rails A and stationary win g-rail B are constructed in general in the usual manner of forming a frog. The movable or spring wing-rail C is, however, constructed in a novel manner. That portion which lies against the point of the frog is reduced in height, as at d., by compressing the web or neck, so as to form an offset c in the base or ila-nge at least equal to the thickness of the iiange of the point. Then the flange next the point is turned or rolled upward, so that it shall not project or extend beyond the line of the head, as shown at c in Fig. 53, thus allowing the head of the said spring-rail to lie closely against the point, and at the saine time maintaining the normal strength of the rail. The raising -plates are in thickness equal to the reduction in hei ght of the springrail,thus forming a truc and firm bearing for the spring-rail.

Longitudincl and upward movements of the spring-rail may be prevented by any of the various means employed in other styles of the spring-rail frogs.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1sn

l. In a railroad-frog, the combinatioinwith the fiogpoint, of a wing-rail having a portion of one of its flanges turned up to lie against the rail-web, adapting its head to lie against the point of the frog, substantially as described.

2. In a railroad-frog, a wing-rail reduced in height where it lies adjacent.- to the point of the frog and with its inner flange turned up ward, so that the head of said wing-rail may lie against the point of the frog, substantially as described.

3. In a railroad-frog, the combination, with the frog-point, of the stationaryv wing-rail, the movable wing-rail with the offset on its underside and upwardly-tu r'ned flange, and the raising plate or plates, substantially as described.

In testimony whereof I have sign ed my name to this specification in the presence of two sub scribing witnesses.
