RAILWAY- FROG.

SPECIFICATION forming part of Letters Patent No. 288,65?, dated NovemberV 20, 188?,

i Application filed April l0, 1,882. (No modil.)

To all who/it it may concern:

Be it known that I, VILLIAM J. MORDEN, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a specification.

My invention relates to an improvement in that class of railway-frogs in'which the different rails are held together by bolts passing through the connecting-pieces and the rails.

In the frogs of this class heretofore employed great trouble is experienced from the loosing andthe ruiming off of the nuts of the bolts, caused by the striking of the flanges of the car-wheels, and by the continual jar to which t-he frog is subjected from passing trains and the object of my invention is to obviate this difficulty, which I do by dispensing with the use of nuts on bolts, and using a plate or plates, which are tapped to receive the threaded ends of the bolts which pass through the rails and connecting-pieces and are screwed into said plates.

In the accompanying drawings, Figure 1 is a perspective view of a frog to which my improvement is applied. Fig. 2 is a crosssectional view of the same. Fig. 3 is a detailed view of the plates and bolts, shown in perspective; and Fig. 4 is a modification of the same. l

Similar letters of reference refer to like parts throughout the several views.

In the accompanying drawings, A repreresents a frog to which Vmy improvement is applied, and which is composed of the side rails, BB, and center rails, B B, connected by U -forined plates C, secured thereto by bolts b, which pass through the U-formed plates and rails, and are screwed into a plate or bar, D, which is of sufficient length to take all the bolts, and thus bring a greater bearing-surface against the rails and U-formed plates, and at the same time dispensing with the objectiona'ble nuts which have heretofore been used.

It is obvious that instead of one' long plate D, several shorter ones, as represented :in Fig.

4, may be used with the same result.

The plates D may be made of iron, steel, or any other material which will serve the purpose. i I am aware of lLetters Patent No. 173,012, dated February 1, 1876, and No. 190, 863, dated May 15, 1877, granted to Ibbotson and Talbot, and that it is the well-known practice to apply tapped-out plates outside of the shbars. I do not claim the same, broadly.

What I do claim as my invention, and desire to secure by Letters Patent, is-

A railway-frog consisting of the side rails, B B, center rails, BB, the U-forlned troughplates C, bars D, and bolts b b, the side rails and center rails being connected by the troughplates, which are secured thereto by means of 6F,

the bolts that pass through the plates and rails and into the Abars D, substantially as and for the purposes described.

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