SPECIFICATION forming part of Letters Patent No. 588,951, dated August 31, 1897. I Application filed February 25,1897. SerialITo. 624,939. (No model!) To (all whom 01- may concern:

Be it known that I, RICHARD OADY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain newand useful Improvements in Railway-Switches, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to railway-switches and to means for operating the same; and the object thereof is to provide an improved switch-operating device which is connected with a railway-track and in operative connection with the usual pivoted switch bar or tongue, and which is'adapted to be operated by devices connected with the platform of a car.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a plan view of a railway-track and showing the rails of a side track or switch and the switch-operating mechanism which I employ; Fig. 2, a section on the line 2 2 of Fig. 1 and showing a car in place on the track, the car being also in section and provided with the device which I employ for operating the switch; and Fig. 3, an end View of said car and a cross-section of the rails of the track.

In the drawings forming part of this specification the separate parts of my improvement are designated by the same numerals of reference in each of the views, and in said drawings, reference being made to Fig. 1, I have shown at 5 the rails of a railway-track and at 6 the rails of a side track or switch, and in the practice of my invention I employ the usual pivoted switch bar or tongue 7, the free end of which is provided with a spring 8, which presses against and is connected with a post or support 9, which is secured between the rails of the main track, and which is adapted to hold the tongue or bar 7 in the closed position.

Pivotally mounted centrally of the main track and at a suitable distance from the switch bar or tongue 7 is a triangular switchoperating lever 10, the longer arm of which is provided with a pin 11, which moves in a transverse segmental slot 12, formed in a plate 13, which is secured between the rails of the main track, and secured at one end of said slot is a bar 14, provided at its inner end with a spring-arm 15, this bar and spring-arm being shown in dotted lines in Fig, 1, and said spring-arm is provided in the side thereof adjacent to the pin 11 with transverse notches or recesses in which said pin operates, and secured to said pin 11 is a rope, cord, or chain 16, and said rope, cord, or chain is passed around a pulley 1S, opposite the free end of the spring-arm 15, and around another pulley 19, opposite the free end of the switch tongue or bar 7, and is then connected with a depending pin 20, secured to the free end of said switch tongue or bar and passed down- Wardly through a slot 21 in the plate 13.

Arranged at each side of the end of the lever 10, opposite that with which the pin 11 is connected, are pins 22, which limit the movement of said lever, and I also provide devices which are connected with the car and by which the lever 10 may be operated, said devices consisting of a vertically-movable bolt or rod 23,"which passes through the platformof the car, and on which is mounted above said platform a spring 24:, and the rod or bolt 23 is provided with ahead 25, and the spring 24: holds the rod 23 in a raised position.

The lower end of the rod 23 is connected with a crank-lever 26, which is pivotally connected at 27 with a hanger 28, secured to the platform of the car, and one arm of said cranklever is also connected with a rod 29, which extends backwardly and is pivotally connected at 30 with one arm of a crank-lever 31,which is pivotally connected at 32 with a bracket or arm 33, which is connected with the'truck of the car, and one arm of the cranklever 31 is directed backwardly and pivotally connected at 34 with a vertically-movable rod 35, which passes through a keeper36 and by which the lever 10 is operated.

The keeper 36, through which the vertically-movable rod 31 passes, is formed on or hangers are springs 30, and said rod is free to move in the hangers 38, but cannot be detached therefrom, and the rod 35, which is connected with the crank 31, is thus capable of a slight lateral movement.

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.

If a car provided with the switch-operatin g apparatus herein described be moving on the main track in the direction of the arrow a and it is desired to operate the switch, all that is necessary is to depress the rod 23, which passes through the platform of the car, and the lever 10, which is slightly triangular in form, as shown in Fig. 1, and the sides of which are also preferably curved, as is also shown in said figures, may be operated so as to open the switch and allow the car to take the side track, this operation being accomplished by depressing the rod 23, which by reason of the crank- levers 26 and 31 and the rod 29 will depress the rod 35, so as to strike the side of the lever and force said lever into the position shown in dotted lines in Fig. 1, and the car can take the side track. I also provide a spring 40, which is secured to the plate 13, and which is designed to bear upon the end of the lever 10 to prevent the spring 8 from closing the switch before the car passes, and the spring-arm of the bar 14 also aids in this operation by hearing 011 the pin 11 of the lever 10.

It will thus be seen that I accomplish the object of my invention by means of a device which is simple in construction and operation and which may be easily applied to any form of a railway-switch.

Having fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a railway-switch-operatin g apparatus, the combination of a lever which is substantially triangular in form, and which is pivoted between the rails of the main track, and which is provided at the end opposite the switch, with a pin which passes downwardly through a slot formed in a plate with which said lever is pivotally connected, a cord which is secured to said pin, and passes around pulleys mounted between the rails of the track, and connected with the free end of the switch bar or tongue, and springs which operate in connection with said pin, substantially as shown and described.

2. In a railway-switch-operatin g apparatus, the combination of a lever which is pivoted between the rails of the main track, and which is provided at the end opposite the switch, with a pin which passes downwardly through a slot formed in a plate with which said lever is pivotally connected, a cord secured to said pin, and passed around pulleys mounted between the rails of the track, and connected with the free end of the switch bar or tongue, said lever being adapted to be operated by devices connected with the platform of the car, and said plate being provided with means for limiting the movement of said lever, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 12th day of February, 1807.

RICHARD CADY.
