'RAILWAY-FROG.

.,IPECIFICATION forming part of Letters Patent No. 332,734, dated December 22, 1835.

Application filed July 30, 185. S

T0 all whom, it may concern:

Beit known that I, WILLIAM J. MORDEN, a -citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a specification, to wit:

This invent-ion relates to railway-frogs; and it consists in certain peculiarities of the coustruction and arrangement of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now prcceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure l is a plan view of a frog constructed as I design it. Figs. 2 and 3 are perspective views of parts thereof, and Figs. 4 and 5 are cross-sections upon the lines x x and y y, respectively.

A represents a frog-point, cast, swaged, forged, or otherwise formed in one piece, with a base, a, projecting upon both sides, as shown in Figs. I and 3. This base is herein shown as formed in one continuous piece upon each side, with notches in its edges at proper intervals to receive the spikes, which confine it firmly to the cross-ties of the road-bed. As the object of this base is to form a solid bearing for the point, a means of firmly securing it in position, and a support for the wingrails, it is obvious that its real value is only upon the ties, and it may be made cheaper and lighter by being cut away between, as indicated by the dotted lines in Fig. 3. The wing-rails B B are bent in proper shape, and at one end secured to the rails of the main track and siding in the usual manner by lishplates and bolts b b, or in any other way found most desirable. These wings are secured iirmly together at or near the throat of the frog by plates c c', shaped to conform to the inner and outer sides of the rails, as in Fig. 4, and bolted through their shanks in the manner usual in similar cases. The wings B B are not secured to the ties, but lie loosely upon the base a, one upon each side of the solid point, and at their rear ends are connected by a cross-bar, d, passing beneath or through the point, to prevent the wings from jumping from their seat, as will be at once understood.

The operation is as follows: One of the wings lies normally in close contact with the point, as represented in Fig. l, and the other is by its connection held away from the point a sufficient distance to allow the passage of the wheelflanges. Should a car approach upon the other track in either direction, the iianges of the wheels strike the wing and throw both of them over, thus always allowing the wing over which the wheels are to pass to lie close to the point and give a solid bearing for the wheels, and prevent the pounding upon the thin end of the point, which so soon destroys it. The wings swing freely from their jointed ends, and their length, together with the short distance moved, prevents any injury to the joint by this motion. The wings are firmly supported upon the base a and move freely to and from the point, as occasion requires, and the base, being formed solid with the point, makes a strong connection free from liability of accident, and very simple and inexpensive in construction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a railway-frog, the solid point A, having projecting base a c upon each side, formed in one continuous piece with the point, and having notches a u, the said base a a forming a support for the movable wing-rails B B and of sufficient width to allow said wings to move freely, substantially as shown and described, and for the purpose set forth.

2. In a railway-frog, a frog-point formed in one solid piece with an integral base projecting upon each side, in combination with a pair ot' wing-rails secured at one end to the track-rails, and having their opposite ends connected together and resting upon the pointbase upon each side of the point, to and from which they are freely moved by the passing wheels, substantially as and for the purpose set forth.

3. In a railway-frog, a solid frog-point having a projecting base or support formed therewith upon each side, in combination with the wing-rails secured at their forward ends to the trackrails andlying loosely upon thebase upon each side ofthe point, and two bars connecting them, one at or near the throat and one at their rear ends beneath or through the heel of the point, .whereby the wings are readily moved to and from the point,to secure a double bearing for the wheels, substantially as shown and described.

y 4. The point A, formed in one piece with the projecting base a, upon each side, having notches at proper points for spiking to the ties, in combination with thewings B B, resting loosely upon the point-base on Veach side 15 of the point and connected at the throat of the frog by bars c c,shaped to fit the rails, and at the rear ends by a bar, d, passing under or through the point, to prevent the wings from jumping, substantially as and for the purpose 2o set forth.

In testimony whereof I afx my signature in presence of two witnesses.
