SPECIFICATION forming part of Letters Patent No. 528,474, dated October 30, 1894.

Application filed March 20,1894. Serial No. 504,432. (No model.)

To all whom it may concern:

Be it known that I, NATHANIEL O. GOLD- SMITH, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Spring-Frogs, of which the following is a specification.

The object of my invention is to make a more reliable and durable spring frog. This 1s .accomplished by employing a continuons rail for the main track and a section of the head being cut out at the point of cross over, the head beveled at each end of the notch and the web of the rail bent so as to bring the same centrally under the beveled points.

The various features of my invention are set. forth in 'the description of the accompanying drawings making a part of this specilication, in which- Figure l, is a top plan view of my improvement in position for use. view of the continuous rail. Fig. 3, is a side elevation of the main rail and a section attached to the wing rail. Fig. 4, is a section on line w, 0c, Fig. 1.

A represents the main track rail. t-ion of thehead at the central portion is cut awzay and beveled at the ends to form points a,

B represents the point of the rail frog forming a continuation of the side track rail B. c, represents the web of the rail at this central point of the cross way, which is bent so as to bring it centrally under'the extreme points a., b.

lrepresents the stationary crossing wing rai C, represents the spring wing rail.

E, represents a solid lling block for uniting the main rail A, to the side rail B.

The spring rail C is connected to the main rail A, by a fish bar joint D.

F, represents a strengthening bar bolted to the outside of the web spring rail C, in front of the -sh bar joint D.

H, represents the ordinary springs attached Fig. 2, is a top plan A Ysecto the friction plate and'frog in the usual manner.

Attempts have been made to use a continuous main rail and a section of the head out out to form points a, b, but the points in such cases are at one side and not vertically over the web of the rail, and have quickly broken down and become dangerous.

I construct my device as follows: I bend the web C, in the position shown in Fig. 2, then cut away a section of the head on the beveled lines leaving the centralportion of the head to form the points, and thus obtain the requi-v site strength and durability. The headof the wing rail C, is inclinedat the points I, J so as to allow the over-lapping section of the wheel tread riding on the rail C, to go on and od the same Without blow or jar.

Having described my invention, I claim- 1. In a spring frog a continuous main rail A, having a section of the head cut away and the web c, bent to come centrally under the points ct, b, formed by cutting away the head of the main rail substantially as specified.

2. In aspring frog thecontinuous main rail A, having a section of the head cut away with the web c, bent to form avertical support for the points a, b, in combination with the stationary wing rail B, and the spring wing rail C, substantially as specified.

3. The combination with the continuous main rail A, having bent web c, forming the vertical supports for the points a, b, of the stationary rail D, a solid filling E, said parts being secured together by through bolts substantially as specified. r

4.. In a spring frog, a main track rail having its continuous web bentto lie directly under two points formed by beveling its head at an angle substantially as specified.

In testimony whereof Ihave hereunto set my hand.

NATHANIEL O. GOLDSMITI-I.
