RAILWAY FROG.
APPLICATION FILED JAN 15.

FATTGRNEYS,
WILLIAM M. MITCHELL, or LOUISVILLE, KENTUCKY.
. RAILWAY-FROG.
- Specification of Letters Patent.
Patented Mar. 30, 1920.
Application filed January 15, 1920. Serial No. 351,550.
To all whom it may concern:
Be it. known that I, \VILLIAM M. MrroI-InLL, a citizen of the United States, residing at Louisville, in the county of- J efferson and State of Kentucky, have invented certain new and useful Improvements in Railway-Frogs, of which I declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specifica tion.
Ihis invention has relation more particularly to that class of railway frogs in which provision is made for preventing the rapid deterioration of those parts of the frog that are subjected to excessive wear, and the invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawing, and more particularly pointed out in the claims at the end of the specification.
While I have illustrated my invention as applied to a familiar type of frog commonly designated a stiff frog, it will be understood that my invention is equally applicable to spring rail or other familiar types of frogs.
Figure 1 is a plan view of a railway frog embodying my invention;
Fig. 2 is an enlarged view in vertical section on line 22 of Fig. 1;
Fig.3 is an enlarged view in vertical section on line 3-3 of Fig. 1.
In'the drawing, A, A designate wing rail sections, B, B point rails and C, C denote wing rail sections of the frog. Between the rail sections A, A are placed one or more N suitable filling blocks D, these blocks being formed with holes for the passage of the usual connecting bolts E. Similarfilling blocksD will be placed between the wing rails C, C and the point rails B, B, but the construction andarrangement of these filling blocks is so well known to those familiar with railway track structures that they need not be more fully described.
Between the inner ends of the rails A, A and of the wing rails C, C are placed the insert rail sections F that extend along the throat portion or flangeway of the frog and at such points thereof as are subjected to excessive wear, these insert sections F being preferably opposite the frog point These insert sections F are formed of a steel material harder than that of which the rails A, A and rails C, C are formed, the heads,
webs and bases of the inserts F being integral and corresponding in cross section to the rails A, A and C, G.
The frog point G is formed with its head, its web and its base integral and of a metal materially harder than the metal of which the pointrails B and B are formed, as the point G, like the insert sections F, F, are
the-parts of the frog subjected to the most excessive wear. As shown, the outer portion 9 of the point corresponds in cross section with the rail B, and the frog G is formed with a shoulder or ofi'set portion 9 against which will bear the tapered end 6 of the rail B.
Upon the outsides of the rails A, A, the insert sections F, F and the rails C, C are arranged the long fish plates or reinforcement plates H through which pass the bolts E that serve to connect the various parts of the frog together, these plates being provided at their threaded ends with nuts (and preferably also with lock nuts not shown) in the usual manner. The plates H set between the head and base flanges of the rails and of the insert sections F, the upper edges of the plates H conforming to the heads and base flanges of the rails and being preferably beveled, as at it, upon their outer surfaces.
By forming the insert rail sections F, F of a cross section corresponding to that of the rails A, A and wing rails C, C, these insert sections can be cheaply and readily made and when secured in position for use, afford an exceedingly strong and durable structure, protecting the parts of the frog about its throat'and where it is subjected to excessive wear and thus prolonging the life of the structure. the frog points G of a steel material harder than that of which the rails are formed and with its head, web and base integral, an extremely strong and durable construction is afforded.
So, also, by forming What I claim as new and desire to secure by Letters Patent is 2- 1. A railway frog comprising the combination with the wing and point rails and section corresponding in cross-section to the wing rails.
2. A railway frog comprising the combination with the wing and point rails and with suitable filling blocks between said rails, of insert rail sections of metal'harder than that of which the wing rails are formed, said insert sections being formed separate from the wing rails and being lo cated opposite the fla-ngeway of the frog, and reinforcement plates arranged outside said wing rails and said insert sections and bolts for securing the parts together.
3. A railway frog comprising the combination with the wing and point rails, of a frog point comprising an insert of metal harder than that of which the wing rails are formed, said insert being formed separate from the point rails and having its head, web and flange integral, and suitable filling blocks between said insert and said wing rails.
4. A railway frog comprising the com bination with the wing and point rails, of a frog point comprising an insert of metal ma- 7 terially harder than that of which the wing rails are formed, said insert being formed WILLIAM M. MITCHELL.
