TO ALL WHOM IT MAY CONOERN:

Be it known that I, JAMES WIXTED, of :Port Carbon, county of Schuylkill, State of Pennsylvania, have invented animprovement in Railroad Frogs; and I do hereby declare the following to be a. full, clear, and exact description ofthe same.

My invention consists in securing the steel points of frogs to the base-plates ol the same in the peculiar K manner fully described hereafter, s o that thepoint may be Jfirmly held in its place .without detracting from-the solidity and strength of the said plates. Y

In order to enable others skilled in the art to make and apply my invention, I will now proceed to describe the `mode of carrying the same into eiect` reference being had to the accompanying drawing, vwhich forms a part of this specification, and in whichr Figure 1 is a plan view of my improved frog.'-

i Figure 2, a vertical section on the line 1 2, g. 1. 1 Figure 3, a transverse section on the line 3-4, g.' 1, and Figure 4, a'transverse section on the line 5-6, tig. 1.

Similar letters refer to similar parts throughoutA the several views. As regards general form, my improved frog is similar' to those of the' usual construction, and consists cf the cast-iron plate A secured to the track by bolts or spikespassing through lugs a, as usual, ribs or rails I and b projectingvfrom the uppersur'ace, and forming a part of this plate, and theseribs being faced with steel in the ordinary manner. There is also between the ribs b and Z1 the usual angular projectio'ne, with a steel facing, f, forming a continuation of the steel point al'.

It is the peculiar manner of securing this steelpoint to which my invention especially relates.. Ordinary steel points are made of a dove-tailed forml atthe lower edge, and are adapted to a dove-tailed recess formed in the plate A,ia recess which tends to weaken the plate-at a point where the greatest strength is required. On referring to fig. 2 it will be seen that the plate A has no recess for receiving the point, the plate being simply k 'thicker at its 'narrow than at its broad end, so that uniformity of strength may be attained. The steel point d is placed on the thinnest portion'of the plate, its extreme point extending to the edge of the thickest portion, the rear of the widest end of the point being overlapped by the end of the steel facingf of the angular projection e, 4as seen in fig.

Itis most'important in all railroad frogs that the point should be so secured as to eifectu'allly resist all lateral strains,` a security d-ependent in ,ordinary frogs onthe recess `in the plate A, which recess cannot be' made withoutrendering the said plate defective as regards strength. To obviate this I'secure to the plate A wrought-iron or steel strips m m, oneon each side of the point d, by bolts, one strip fitting accurately between ea'chrib b and I1 and the point, so that the lateral strains imparted to the latter will be resisted by these strong ribs orrrails instead oi' being communicated to aplatc, A, so weakened by a recess as to superinduceits fracture.

I claim as my invention, and desire to secure by Iietters`Patent The steel point d, confined to the plate A of a frog, and between the rails or ribs b and b' of the same, by p the wrought-iron or steel strips m m, all substantially as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnessesg JAMES WIXTED.
