RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 767,144, dated August 9, 1904.

Application filed May 5, 1904. Serial No. 206,589. (No model.)

To all whom it may concern:

Be it known that we, WILLlLAM E. GRUMBINE, residing at Baltimore, in the State of Maryland, and CHARLES E. BECK, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, citizens of the United States, have invented new and useful Improvements in Railway-Switches, of which the following is a specification.

Our invention relates to new and useful improvements in railway-switches and means for operating the same; and its object is to provide a simple device which can be readily placed upon a railway-car and by means of which the tongue of a switch can be shifted in a desired direction without the necessity of stopping the car during its approach toward the switch.

Another object of the invention is to provide means whereby the operating mechanism can be held out of operative position.

With the above and other objects in view the invention consists of a switch-tongue having a spring-pressed pin normally projecting therefrom adjacent the point thereof. This pin is adapted to be shifted laterally by a shoe which is secured to the lower end of a vertically-movable stem arranged in the front platform of a car and adapted to be rotated by means of an operating-lever provided therefor. A latch is located in this lever for locking the stem in raised position. Springwings are located on the shoe, so as to provide resilient means for operating the pin and tongue.

The invention also consists in the further novel construction, combination, and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, and in which- Figure 1 is a plan View of the switch of a track, said track being shown provided with a slot at the center thereof for the reception of a plow or grip and the switch-operatingshoes being shown in position adjacent the tongues. Fig. 2 is an enlarged longitudinal section through the switch-tongue. Fig. 3 is a section through the portion of a car and showingthe operating mechanism partly in sect1on. Fig. 4: is a horizontal section through a portion of the operating-lever of the meoh' spring-strip 8, which contacts with the lower end of a pin 1 and serves to hold said pin normally projected from the upper face of the switch-tongue. Secured to the front platform of a car is a bracket 5, in which is slidably mounted a stem 6, the lower end of which is secured to an ear 7, projecting upward from a shoe 8. The front end of this shoe is pointed and has oppositely-curved wings 9 projecting therefrom and formed, preferably, of spring metal. The downward movement of the stem is limited by contact with the bracket 4: of an enlarged portion 10. of the stem. This enlarged portion is preferably angular and is slidably mounted within a lever 11, which is arranged upon the platformand is slidably mounted on a base-plate 12. Stop-pins 13 are located at opposite sides of the base-plate for the purpose of limiting the lateral movement of the lever. A springpressed rod 14: is slidably mounted within the lever and has an arm 15 projecting upward from the lever whereby the rod can be drawn longitudinally within the lever, so as to contract the spring 16, which is located upon the rod. The rod is adapted to be held by said spring normally in engagement with a recess 17, formed within the enlarged portion of the stem 6. A loop or handle 18 is formed at the upper end of the stem for the purpose hereinafter more fully described.

WVhen it is desired to shift the tongue l'of the switch by means of the mechanism located upon the car, the rod 14 is drawn away from the stem 6 and if in engagement with the recess 17 will release the stem and permit it to fall by gravity with its enlarged portion 10 resting on the bracket 4. Lever 11 is then swung against one of the stop-pins 13 and the stem is caused to rotate therewith, thus bringing the point of the shoe in position to contact with one side of the pin 4:. As the car goes forward this pin will be shifted laterally by the shoe, and the s pring-wing 9, which is contacted by the pin, will give sufliciently to allow theshoe to pass the pin without injury thereto. The car will thus move in thedirection desired, and the wheels thereof upon contacting with the pin 4 will depress it. The pin is returned to its normal position after the wheels leave it. When it is desired to remove the shoe from operative position, it is merely necessary to draw the stem 6 upward by gasping the handle 18. Rod 14 will auto v fsaatically engage the recess 17 when it regis firs therewith, and the stem will thus be supported in raised position. Where the apparatus is used upon a track having a slot between therails thereof, similar mechanism may be employed for shifting the tongue located within the slot. In Fig. 1 we have shown a tongue 19 in the slot and a shoe in position for shifting it simultaneously with the tongue 1.

In the foregoing description we have shown the preferred form of our invention; but we do notlimit ourselves thereto, as we are aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and we therefore reserve the right to make such changes and alterations as fairly fall within the'scope at one end of the stem, oppositely-disposed Spring-Wings extending from and integral with the shoe, and means for locking the stem in adjusted position. i

3. Switch-operating mechanism, comprising a vertically-movable revoluble stem, a lever for rotating the stem, a stem-lockingdevice within the lever, a shoe connected to the stem and spring-wings integral with the shoe.

4:. Switch-operating mechanism, comprisinga vertically-movable revoluble stem, a shoe at one end thereof, oppositely-disposed spring- Wings upon the shoe, a lever inclosing and adapted to operate the stem, and a springcatch within the lever for engaging and looking the stem.

5. Switch-operating mechanism, comprising a base-plate, stop-pins thereon, a lever slidably mounted on the base-plate, a springpressed rod slidably mounted within the lever, a recessed stem slidably mounted within and revoluble with the lever, a shoe at one end of the stem, and oppositely-arranged curved spring-wings upon the shoe.

6. The combination with a switch-tongue having a spring-pressed pin projecting therefrom; ofmechanism for operating said tongue comprising a revoluble stem, a shoe at one end thereof, oppositely-arranged spring-wings upon the shoe and adapted to contact with the pin, a lever for rotating the stem, and a stemlocking device within the lever.

In testimony whereof we afiix our signatures in the presence of witnesses.
