THOMAS H. PERRY, OF BLOOMINGTON, ILLINOIS.

' RAILWAY-FROG.

SPECIFICATION forming partof Letters Patent No. 352,066, dated November 2, 1886.

Application filed March 12, 1886. Serial No. 195,009. (No model.)

To all whom it may concern:

Be it known that I, THOMAS H. PERRY, a citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented a-new and useful Railway-Frog, (for which I have not obtained Letthe following is a specification.

It is generally understood bythose who are conversant withthe construction and maintenance of railways that the tread of locomotive and car wheels wear next to their flanges three to four inches wide by from naught to three-quarters inch deep, (more or less, according to service,) and wearing the treads into a groove shape, leaving a flange. something similar to its gageflange, formed Such wheels are usually called guttered, andthis outeror guttered flange, falling below the bearing-tread, comes in contact with the members of a-T- rail frog at their crossing points. This contact is in such manner an increment of forces that constitutes an extraordinary element of destruction, and is destructive, toa great de 'gree, of the frog and the railway equipment operating it. Heretofore T-rail'railway-frogs have been constructed without appliances or of a mechanism that overcame in the best manner this destructive effect of the outer flange of a guttered wheel.

My invention relates to improvements in T-rail railway-frogs, and the object of my im provements is to overcome the destructive effect of the outer flange of a guttered wheel at its point of crossing the several members of a T-rail frog. I attain this object by the mechanism illustrated in the accompanying drawings. v I

Figure 1 is the top view of a Trail frog, and showing a guttered wheel tread relative thereto. Fig. 2 is a top, View as the frog ap- Figs. 3 and 4 are vertical sections of the improvements on the line 1 2 and 3 4., respectively; and Figs. 5 and 6 are vertical sections'of the improvements on the line 5 6 and 7 8, respective1y.

- Similar letters refer to similar parts throughout the several views.

a a are the T-rail members'that form the point of a T-rail frog.

b b are the wing-rails.

, c is the outerflange of a guttered wheel.

d d are the lines traversed by the outer' flange incither direction, and show the points of impact e with the several frog members.

F is a filling-block, cast or forged of hard metal,0r a combination of metals, fitting neatly in filling the acute angle of the diverging frog ing, and by'which the guttered wheel-flange is carried up to and over the frogs face in clearance of any impact at the points .6 of the frog members a a.

M is a metal block, neatly fitted and secured to the outer vertical face of the wing-rails b b. In itsmanner of construction and effective operation it is similar to the filling-block F-z'. 6., it gives to the wingrail a width of wheelbearing tread and in supporting the guttered flange to'the crossing point on a plane level with the frogs face. These blocks have the inclined-face approaches as an easing, similar to the filling-block F, and by which the .guttered flange is carried up to the frogs face and over the points of impact 6 of the wing-rails b b without a shock.

I am aware that prior to my invention T- rail frogs having various devices for their strength and durability have. been constructed. I therefore do not claim such a combination, broadly; but

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

1. The combination, in a frog, with the Wingrails, of the re-enforcing blocks located on the sides of the same, substantially as set forth.

2. The combination, in a frog, with the wing-rails having-the re-enforcing blocks, of the members a aand the filling-block between them, substantially as set forth.
