RAILROAD-FROG.

Specification of Letters Patent. Pat nted J an. 24, 1911.

Application filed July 17, 1909. Serial No. 508,141.

To all whom it may concern:

Be it known that we, JOHN HOSKYN and J OSEPH H. BIDDEMEN, citizens of the United States, residing at Buffalo county of Erie, and State of New York, have invented certain new and useful Improvements in Railroad-Frogs, of which the following is a full, clear, and exact description.

Our invention relates to railroad frogs and more particularly to reversible railroad frogs.

In producing our invention we have sought to provide a railroad frog in which it would be impossible for persons traveling over it to catch their feet in it and also to provide a device in the construction of which no bolts, screws or rivets need be employed. Moreover the device herein described is one which is reversible and therefore has double the wearing qualities of the ordinary nonreversible frog.

By means of the device herein described we have attained the advantages above set forth. Many other advantages than those herein set forth will be evident to those skilled in the art.

Referring to the accompanying drawings forming part of this specification in which similar letters of reference indicate corresponding parts throughout the several views and in which:

Figure 1 is a perspective of our frog showing it in place and connected with the rails and ties. Fig. 2 is an enlarged view of the wing rail end of Fig. 1 with the rails removed. Fig. 3 is a view partly in plan and partly in section of one-half of our frog and is taken on the line E-F of Fig. 2. Fig. 4: is an enlarged view of the tongue end of Fig. l with the rails removed. Fig. 5 is an enlarged sectional view taken on the line AB of Fig. 2. Fig. 6 is an enlarged sectional view taken on the line C-D of Fig. 2 and in addition thereto shows a section of a car wheel in place upon the tread area of our frog.

We will designate that part of our frog located at 20 as the throat. That part of Fig. 1 at the left of the throat 20 we will call the throat end and that part to the right of the said throat the tongue end. That part of the rail portion of our frog at the left of the throat 20 we will designate as the rail treads 6 and that part at the right of the throat the wing rails 6 The rail portion 6 composed of the rail treads 6 and the wing rails 6 is provided with guards 5 which are slightly beveled and which rise vertically from the extreme outer edge of the rail portion 6. These guards prevent the car wheel from leaving the track should its flange by any mishap leave the channel ways 7. The guards 5 are flared somewhat at their ends 8 and 9 and are preferably reinforced at their points. The rail treads 6 are of such a width that there is a suitable clearance space 17 (see Fig. 6) between the guards 5 and the outer edge of the rim of the car wheel 22. Should a car wheel when entering the frog by any chance have a tendency to ride upon the tops of the guards 5, the flared ends 8 and 9 would throw the wheel back in its place and the reinforcement at these ends would be ample to withstand the shock. The two sides of the tread area 21 of the tongue end 19 of our frog converge at the apex or point 10 (see Figs. 1 and 2).

As clearly shown in the several accompanying views the conformation of the upper and lower faces of our frog is identical thus making it possible to use either face as desired and adding thereby very greatly to the life of the frog. The rail portion 6 and tread area 21 of that face of the frog which is not in use form the base of the frog and the guards 5 of that face are let into the cross-tie (see Figs. 1 and 6) thus providing means which prevent lateral displacement of the frog. Each side of the throat portion of the frog (see Figs. 1, 2 and 6) is recessed at 12 and this recess is preferably provided with ribs or webs 13 for strengthening purposes. This construction reduces the weight of the frog and provides means for using spikes to assist in fastening the frog to the cross-ties. In a like manner the tongue portion 19 of the frog is cored out at 1d (see Figs. 2 and 5) and is provided with supports 15 for strengthening the upper and lower surfaces. At both ends of the frog we provide mortises or rectangular cavities 16 each of which is adapted to receive one end of an ordinary fish-plate and thus the rails to which the fish-plate is secured are locked in proper lateral relation with the frog.

By the use of our frog we provide a very smooth passage for the car wheels 22 from the rail portion 6 to the tread area 21 or vice versa and thereby the wear and tear on the frog as well as on the rolling stock is reduced to a minimum.

Having thus described our invention it will be apparant to those skilled in the art that it has many points of merit and advantage some of which may be mentioned. Thus when our invention is used no outer or inner guard rails are necessary and the cost of material and labor in supplying the same are done away with. Moreover in our device no wooden wedges need be used. Owing to the absence of all bolts, screws, rivets and nuts, there is no shake or rattle of our frog when in use and therefore it is less subject to wear and tear than the ordinary frog. Our device is simple to manufacture and when made of the best steel it is as solid, safe and durable as the rails themselves. The cost of manufacture of our device and the cost of installation is less than in the case with the frogs now in use. Our device is easily installed and can be put in place or changed in a very short time.

Because of the fact that our frog is reversible and double faced, there is always an extra frog ready for use and on the ground in case of accident or wear. Another advantage of our frog is due to the fact that the channel ways 7 as well as the guards 5 are beveled outwardly thus making it impossible for anyone to plug the frog and thereby cause the car wheels to jump the track and wreck the cars.

Having thus described our invention what we claim is:

1. As a new article of manufacture a railroad frog comprising a rail portion, straight guards integral with said rail portion and running parallel with the rails of said rail portion and flared at their extreme ends, and a tongue portion.
