J. E. CONLEY FROG I Filed Dec. 51,

JOHN E. CONLEY, OF MEMPHIS, TENNESSEE.

'- FROG.

Application filed December 31, 1921.

This invention relates to railway frogs and has for its object to provide a new and improved device of this description. This invention has among other objects to provide means for converting an ordinary rigid frog into a frog that gives positive guidance to the wheels.

The invention has other objects which are more particularly set forth in the following description.

Referring now to the accompanying drawings Fig. 1 is a plan view showing a frog embodying the invention, wherein the ordinary rigid rolled rail frog is shown separated from the other parts;

Fig. 2 is a plan view of the device shown in Fig. 1 with the parts fastened together to form the complete frog;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2;

Fig. 4 is a sectional View taken on line l4t of Fig. 2.

Like numerals refer to like parts through out the several figures.

Referring to Fig. 1, I have shown the ordinary rigid frog at the center, made up of

rails

1, 2, 3 and 4. Such a frog is defective in that it does not give positive guidance to the wheels passing over it. In order to provide for this guidance I arrange the two sections 5 and 6. These sections are made to fit the rolled rail sections, and in forming the frog it is only necessary to bring them into proper relation and then hold the parts in this relation by the fastening devices 7 which are shown as bolts having the removable nuts '7 so that the parts can be assembled and disassembled as desired. These guard sections are each provided with a raised guide 8 which guide the wheels safely through the frog. These side sections are preferably provided with ribbed spike flanges 9, having the holes 10 for the spikes. By means "of this device I can easily and quickly convert an ordinary rigid rolled rail frog into a safe frog hav ing guiding means for safely guiding the wheels therethrough, and this can be done easily and cheaply. The side sections may Serial No. 526,150.

be of manganese steel or other material and are made to fit the rolled rail sections with out the necessity of machine work and without requiring the rail sections to be cut to lit the side sections 5 and 6.

In the claims I have used the term cast as describing parts of the frog and I use this term to include forged sections also, the essence of this invention being that these parts of the frog are not rolled or rail sections and are combined as set forth.

I claim:

1. A railway frog comprising a central rigid frog section and two side cast sections adapted to be connected with the central sec- 05 tion, the side sections having guides for the wheels integral therewith.

2. A railway frog comprising a central rolled rail rigid frog and two side cast sections adapted to be connected with the central sections, the side sections having guides for the wheels integral therewith.

8. A railway frog comprising three parts, a central part made of rolled rails, and two side parts of cast metal, the side parts fit- 75 ting the sides of the central part, and removable fastening means for holding all the parts together to form a complete frog, the side parts having guide rails for the wheels integral therewith.

4. A railway frog comprising a central rolled rail rigid frog, two side cast sections adapted to be connected with the central section, the side sections having guides for the wheels, and spike flanges integral therewith.

5. A railway frog comprising a central rolled rail rigid frog section, two side cast sections adapted to be connected with the central section, the side sections having guides for the wheels, spike flanges and reinforcing ribs all integral therewith.

6. A railway frog comprising a central rolled rail rigid frog section, two side cast sections adapted to be connected to the central section the side sections having at the top integral therewith guides for the wheels and at the bottom integral therewith spiked flanges, said spiked flanges bein enlar ed. at predetermined points and reen rcing ribs 190 connecting with said enlarged portions of for the Wheels and means for fastening the the spiked flanges. side sections to the central section.

7. A railway frog comprising a central Signed at Chicago county of Cook and 10 rigid frog section and two side sections State of Illinois, this 14th day of December 5 separate from the central section and eX- 1921.
