RAILWAY-SWITCH.

To all whom it may concern: I

Be it known thatI, GRovER O. PHINNEY, a citizen of the United States, residing at Marble Falls, in the county of Burnet and State of Texas, have invented certain new and useful Improvements in Railway- Switches, of which the following is a speci fication.

My invention relates to improvements in railway switches, and has for its leading object the provision of an improved triple switch.

The further object of my invention is the. provision in a triple way railway switch of improved means for returning the various switch points to such position as to leave the main line open when the retaining bars for throwing the switch points of the sidings are released. I 7

Other objects and advantages of my improved railway switch will be readily apparent by reference to the following description taken in connection with the accompanying drawings, and it will be seen that I may make any modifications in the specific structure shown and described within the scope of my claims without departing from or exceeding the spirit of the invention.

Figure 1 represents a plan view of a trackway including my triple switch, the main line being shown as open. Fig. 2 represents a similar view showing the switch thrown to send the train into one of the sidings, and Fig. 3 represents asectional view on the line 3-3 of Fig. 1.

In the drawings, the numerals 1 .and 2 designate the parallel portion of the track which will be termed the main line in the following specification, said portions 1 and 2 having the diverging sections 3 and 4 which form the outer rails of the branch tracks or sidings the various rails being supported by the customary ties 5.

Mounted upon the road bed and in alinement with the rail 1 is a rail 6 while disposed in alinement with the rail 2 is a rail 7, these rails together forming the continuation of the main line. Disposed parallel to the rail 3 is a rail 8 adapted to form the inner rail of one of the branch tracks, while extending parallel to the rail 4'is a rail 9 forming the inner rail of the other branch track or siding. These rails are formed at their intersections with the customary grooves 10 to permit of the passage of the flanges of the car wheels while the rails 8 Specification of Letters Patent.

and 9 intersect in thefrog or point-11. To

cause the cars to run from the main rails 1 and 2 to therails 6'and 7, I pivot at the ends of the rails 6 and 7 the switch points 12, while pivoted at the end of the rail 8 is a'switch point 13 and pivoted at the end of the rail 9 is a switch point 14, the points 13 and 14 being normally disposed sufiiciently inward from the rails of the main line to allow a free passage of the wheel flanges. i

A transversely extending rod 15 has its ends secured in the rails 3 and 4 and has its intermediate portion-slidably engaged in apertures 16 formed in the various switch points thereby preventing upward movement of the same. A spring 17 is wound on the said rod 15 and has its ends secured to the ends of the switch points 13 and 14, said spring serving to draw the points inward toward eachother. To limit said inward drawing of the switch points, I secure to one of the ties the abutment block 18 projecting upward between the ends of the points 13 and 14, which limits the inward movement of said points.

To enable me to so shift the various switch points as to cause the .train to pass onto either siding as desired, I connect the point 12 of the rail 6 and the point 13 by the bar 21 connected to the operating switch stand 22, while I connect the point 14 and the point 12 in alinement with the rail 7 by the bar 19 leading to the switch stand 20. It will thus be seen that the shifting of the bar '21 will move the switch points to cause the 2 onto the siding formed by therails 3 and 8 while the shifting of the bar 19 will so move the points as to causethetrain to go on the siding formed by the rails 4 and 9. When "the points are shifted in either of these directions, the upwardly projecting abutment block 15 .will prevent inward movement of the switch points 13 and 14. Upon shifting of the bar 21 the switch points will then be in a-position,to allow the train to pass vupon'the siding formed by the rails 3 and 8, and upon movement of the bar 19 the train is permitted to pass upon the siding formed by the rails 4 and 9.

way switch will be readily apparent and it will be observed that I have provided an im-,

proved controlling device for said switch in switch points pivotally supported between the rails and having their ends slidably mounted on the rod, a spring connecting the points and wound on the rod, and an abutment block projecting between the rails for limiting the inward movement of the switch points.

2. The combination with a railway trackway including a main line and diverging sidings', of a rod connecting the various rails, switch points having one end pivotally secured in alinement with certain of the rails and having their ends slidably engaged on the rod, a spring wound on the rod and having its ends secured to two switch points of diflTerent pairs, an abutment block interposed between'sai'd connected switch points, said bars connecting the various switch points in pairs for shifting the same to open the sidings, whereby shifting of either pair of switch points will stretch the spring and the contracting force of the spring will reshift the points upon releasing of the bar to open the main line.

In testimony whereof I aflix my signature,

in the presence of two witnesses.
