RAILROAD-SWITCH.

Specification of Letters Patent.

Patented Nov. 10, 1914.

To all whom it may concern:

Be it known that I, EDWARD ENGLE, a citizen of the United States, residing at Pittsburg, in the county of Crawford and State of Kansas, have invented new and useful Improvements in Railroad- Switches, of which the following is a specification.

This invention relates to railway switches, the primary object thereof being the provision of a switch constructed so that, when the switch is closed, the main line is unbroken, thus permitting the passage of roll-. ing stock therefrom without danger of splitting the switch or pounding the rails at the breaks therein, which latter are present in switches of ordinary construction.

A further object of the invention is to provide movable switch points which are adapted to .carry the wheels of the rolling stock from the main line track, over the inner rail, and onto the siding, with the assistance of a movable frog member.

A still further object is the provision of means for bracing the movable frog member so as to prevent lateral displacement thereof due to the'stress thereon caused by the rolling stock when passing onto the siding.

Another object is to provide means for guiding the movable frog member during its movement so that the same will move smoothly into operative position without danger of vertical displacement thereof.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a plan view showing the switch closed; Fig. 2 is a side elevation thereof. Fig. 3 is a plan View showingthe switch open. Fig.4 is a transverse sectlonal view taken on the line llff of Fig. 1. Fig. 5 is a partial transverse sectional view taken on the line 55 of Fig. 3. Fig. 6 is a transverse sectional view taken on the line 6-6 of Fig. 3. Fig. 7 is a longitudinal sectional view taken on the line 7-7 of Fig. 1. Fig. 8 is a fragmentary side elevation of one of the movable switch points, showing its pivotal connection to the switch rail.

In the drawing, 1 and 2 designate the main track rails and 3 and 4 the rails of the siding. The rail 1 is provided with a frog section 5 which is in direct alinement therewith and is closely connected thereto with- Application filed September 6, 1912. Serial No. 718,959.

1 out interruption. the inside of the rail 5 a fixed frog member 6 is formed having an angular extension 7 in alinement with.

the rail 4 forminga continuation thereof.

A movable frog member-8 has one end pivotally connected totheend of the rail 1, as at 9, and has its tread surface 10 inclined upwardly, as at 11, to the elevated horizontal portion 12 thereof. This member is out away at 13 so astoreceive the frog section 5 of "themain line rail 1 and forms thereby a reduced ball or tread portion 14, which latter is adapted to overlie the. frog section '5 and the fixed frog member 6 so as to .aline with the portion 7 thereof, the tread surface at the end of the portion 14: being beveled downwardly to meet the tread surface 15 of the said portion 7 of the fixed frog member when in this position. A beveled enlargement'lG formed on the upper surface of the frog member 6 is provided with an'inclined active face 17 adapted to engage the portion 14 of the movablefrog member when in operative position and the switch is open, to brace the said movable member upon lateral stress thereon due to the passing of the rolling stock onto the siding.

An attaching member 18 is secured to the inner face of the movable frog member 8 and is provided with a reduced tongue 19,

which is slidably mounted within a horizon- 23 secured to the said plate 21. v A connecting rod 24is pivotally connected at one end tothe attaching member 18, as at 25,. andis pivotally connected atits otherendtoithe] crank arm 26 formed on one end of the transmission shaft 27, the said shaft being journaled in suitable bearings 28 mounted upon the cross ties. A switch throwing lever 29 is secured to the upper end of a ver tical operating shaft 30 rotatably mounted on one of the cross ties adjacent to the opposite end of the shaft 27 This lever 29 is provided with avertically movable locking member 32 adapted to engage in one of the locking notches 33 or 34 so as to prevent r0- tation of the said shaft 30. A lateral extension 35 of the said shaft is provided with an upturned pintle 36 to which is pivotallyattached one end "of the connecting rod 37,.

' means of suitable bolts 4-? and are pivotally connected to said crossbar by means of the bolts 48. The end of the connecting rod 37 which is attached to the lateral extension 35 of the operating shaft 30 is provided with a laterally extending pintle 5L9, which has pivotally connected thereto the outer ends of athird connecting rod 50, Whose opposite end is pivoted to a crank arm 51 car ried by the adjacent end of the shaft 27. Motion is thus imparted to the said shaft upon operation of the shaft 30, so as to throw the movable frog member 8 simultaneously with the throwing of the switch points, 41 and 4:2. The said switch points 41 and 42 are provided with elevated tread portions 52 and 53, respectively, the tread surface adjacent the pivoted ends of the said switch point being inclined upwardly thereto, as at 54 and 55. The webs and base flanges of the switch point are recessed longitudinally, as tit-56 and 57, for the reception of the main linera-ils, the elevated tread portions thereof being adapted to overlie the. said main line rails, in order that the rolling stock; may be carried over the main line rail, with the] assistance of the movable frog member 8, the ends of the tread portions of the switch point being beveled downwardly, at 58 and 59, to meet the tread surface of the main line rails 1 and 2.

In operating the switch so as to open the same and permit the train to pass onto the siding, the operating ever 29 is thrown so that the locking member 32 will, engage in the notch 33. The movable switch points I are thus; thrown into engagement with the main line rails, andthem'o'vable fr gmm her is swung over the frog section 5 of the main line rail due to engagement with the tension 5 of the main line rail 1.

upper surface of the fixed frog member 6 and its angular extension 7,the portion 14: of the said movable frog being al s o in engagement with the active face 17 0f the enlargement or stop member 16. As the train moves onto the siding, the outside wheels thereof will tend to force the movable frog member laterally, but its tendency will be restrained by the said enlargement l6 and also due to the engagement of the body portion of the said member with the frog ex- In order to close the switches, the locking member 32 is lifted out of engagement with the notch 33 and the lever 29 is thrown so that the said member will engage in the notch 34, the movable switch points and the movable frog member being thrown clear of the main line rails during this operation, thus leaving the said main line rails free for the passage of rolling stock thereover.

What is claimed is: In a railway switch, the combination of a main line rail, a siding rail including alining portions terminating adjacent to the sides of the main rail, a supporting plate connected with said rails and forming a base for the same, a, movable frog member pivoted to one of the siding rail portions and being horizontally movable upon the said plate and having an elevated tread portion adapted to overlie the main line rail in registration with the other portion of the siding rail in operative position, means by which said movable member may be rendered either operative or inoperative, a longitudinally extending tongue provided upon the base of the movable frog member at the free end thereof for engage ment with the supporting plate, and a guide bracket mounted upon the upper face of the supporting plate and having an offset extension overlying the said tongue for frictional engagement with the upper face of the same. 1

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