Patented. Nov. 29, 1921.

Application filed May 31, 1921. Serial No. 474,024.

To all whom it may concern Be it known that I, NIooLA A. Con'rnsn, a subject of the King of Italy, residin at Bovey, in the county of St. Louis and btate of Minnesota, have invented certain new and useful Improvements in Railroad- Frogs, of which the following is a-specification, reference being had therein to the accompanying drawing.

This invention relates to railroad frogs and has special reference to a separable frog, the parts of which may be taken out and renewed when worn, the principal object of the invention being to provide a more practical form of frog than at present known, and one which may be conveniently repaired and more readily handled than the one-piece solid frog now in common use.

Other objects and advantages will appear in the further description of the invention.

Referring to the accompanying drawing forming part of this application in which like reference characters indicate like parts:

Figure l is a perspective view of one of the improved frogs, completely assembled;

Fig. 2 is a reduced perspective view of the foundation portion of the frog with the rail sections removed therefrom;

Fig. 3 is a perspective view of one of the angular rail sections which is cooperatively engaged with the foundation section;

F ig. 4 is a similar view of one portion of the frogpoint;

Fig. 5 is a similar view of the other portion of the frog point;

Fig. 6 is a transverse section on the line 6-6, Fig. 1;

Fig. 7 is a transverse section on the line 7-7, Fig. 1;

Fig. 8 is a transverse section on the 1m 8-8, Fig. 1;

F ig. 9 is a transverse section on the line 99, Fig. 1.

1 represents the cast metal base or fundation of the frog, which, in general, is of the usual shape employed for such purposes. Upon the upper face of the base and cast integral therewith is the centrally disposed Y-shaped member 2 and the V-shaped member 3. Upon the ends of the bifurcated portion of the Y-shaped member are upwardly projecting enlargements 4 which form continuations of the heads of the angular or wing rail sections 5, when in position. The if-shaped member 2 is cut-away upon either side thereof as at 6 for the reception of tin projecting base or flange of the rail sections when applied thereto and the upper face of the base portion is chamfered or recessed for the reception of the base of the rails so that the rail sections when properly assembled in the base are virtually embedded therein and suitable spikes may be employed for holding them in position.

The point of the frog comprises two pieces of rail sections 7 and 8, the former carrying the entire portion of the extreme end of the point, as indicated at 9, the innermost extremity of which is notched as at 10 for the cooperative reception of the chain fered end 11 of the portion 8 so that when assembled within the frog foundation, one portion upon either side of the V-shaped member 3 they will unitedly form the complete switch point. The upwardly projecting members 2 and 3 preferably extend upwardly approximately the height of the or dinary foot block so that in this form of frog no foot block is necessary in providing safety as required.

I have shown a plurality of through bolts 12 which may be arranged as desired for firmly uniting the various parts of the frog, and, if necessary, fish plates indicated at 13 may be employed. 7

From the foregoing it is evident that l have provided a form of separable frog, portions of which may be conveniently renewed or repaired as desired, and one that may be readily taken apart for transporting, or; the foundation of the frog made a permanent fixture and the rail parts thereof repaired or renewed at will. the benefits derived therefrom being obvious.

Having; thus described my invention, what I claim and desire to secure by Letters Patent, is: I

A separable frog of the character described comprising in combination a base separable parts of the frog, substantially as portion having a Y-shaped upwardly exdescribed. 10
