DEVICE FOR OPERATING RAILWAY-SWITCHES.

SPECIFICATION forming part of Letters Patent No. 571,006, dated November 10, 1896. Application filed February 17, 1896. Serial No. 579,636. (No model.)

To all whom it ntay concern.-

Be it known that 1, JOHN A. MARSH, of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in a Device for Operating Railway-S witches, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to improvements in a device for operating railway-switches and it consists in the novel arrangements, construction, and combination of parts, as will be more fully hereinafter described, and set forth in the claims.

The object of my invention is to construct a device by which to operate a switch either way by means of a device secured to the front end of the car, and which is operated by the motorneer or operator of the car.

The device is detachably secured to the car for the purpose of only using one attachment for the entire car instead of providing one at each end thereof.

Another feature is, if at any time the car is to be turned in for repairs, a new oneis then substituted. It maybe that this car has no switching device, so then one from another car is taken off and placed on the substitute; and so with the attachment, should it become broken through accident, it can be easilyreplaced with a new one without much time or difficulty. It is constructed simple and complete, cheaply manufactured, and can be easily manipulated.

Referring to the drawings, Figure 1 is a perspective view of a street-car, showing my invention applied thereto. Fig. 2 is a vertical sectional view of my complete invention, showing the foot-operating device. Fig. 3 is a vertical sectional viewtaken on the line AA of Fig. 2. .Fig.4 is a top plan view of the switch or frog with the wheel of my invention in position for operation. Fig. 5 is a top plan View of the attachment. Fig. 6 is a view of one side of the wheel. Fig. 7 is a view of the other side; and Fig. 8 is a vertical sectional view of the same, taken 011 the line B B of Fig.7. Fig. 9 is a vertical sectional view of the upper operating portion of my device to an enlarged scale. Fig. 10 is a top plan view of the fastening device by which the attachment is secured to the car. Fig;11 is a perspective view of the socket portion of the fastening device, which is firmly held to the car, and in which the attachment is held.

In the drawings, 1 is an ordinary railwaycar to which my invention is applied.

2 indicates my complete invention, which consists of a shell or tube 3, in which is operated a rod or tube l, by which the wheel 5 of the switching device is operated.

To the bottom of the rod or tube 4 is provided a fork 6, in which is held the wheel 5, for the purpose aforesaid. Said wheel is provided with a depression or cut-out portion 7 at one of its sides for the insertion of a spring 8, and which is supported by the shaft 9 on which the wheel 5 operates.

The wheel 5 is shorter in diameter in crosssection than the distance between the prongs 10 of the fork 6, which is for the purpose of allowing the said wheel 5 to adjust itself to the switch according to its position, and the spring 8 is for the purpose of supporting the wheel and keep it rigid and to one side of the fork G, as shown in Fig. 2.

To the rod or tube 4 is secured a collar 11, which is held thereto in any desirable manner, and rests upon a spring 12, located in the shell 2 for the purpose of raising the wheel and its supportings when the switch has been operated, after it has been operated or pressed down by the foot-lever 13, located upon the platform of the car, said lever passing through the floor 0f the platform, and is secured to an arm 14, which passes around the rod ortube 4, and which lowers the wheel when the lever is pressed upon.

The wheel 5 has on its one side anincline cl, which extends from its extreme outer circumference e to the edge of the depression 7, in which the spring rests. On the other side of said wheel is a flange or hub f, which forms a direct right angle g, which is to ride upon the track 15 when the device is lowered to operate the switch.

. Vithin the depression or bore 7 is a hub 7 which forms part of the wheel 5 and acts as a support for the spring 8.

- To the upper portion of the shell 2 I provide a device 16, by which the tube or rod 4 is turned, and it consists of a collar 16, which is provided on its flange with two slots 17 On the top and extending within isasimilar col- Fig. 4.

turn therein.

Upon the top of the collar 18 is an car 20, in which is hinged a lever 21. This lever is for the purpose of turning the rod or tube 4, in order to place the wheel 5 in position to opcrate the switch according to the direction so desired, and when this is done the lever is lowered and placed in the slot 17, thereby locking the same and keeping the wheel in the placed position. I

To the rod or tube at I provide a feather or key 20, which slidesin a keyway or groove 30, formed in the collar 18, for the purpose as before mentioned.

The collar 16 is firmly held to the shell 2 by a set-screw 22 or any other means well known to the trade.

To both ends of the car 1 and firmly secured thereto are steel castings 23, which are provided with. a dovetailed tapered groove 24:, in which is inserted a male dovetailed steel casting 25, which is firmly secured to the shell 2 of my device. These are for the purpose of holding my device to the car and disconnecting it when so desired. In order to handle the same to remove or replace it, I provide said shell with handles 26. (See Figs. 1 and 3).

In changing my device from one end of the car to the other I first disconnect the pin 27 from the foot-lever 13, and I then raise the lever 13 from the arm 14,. I then disconnect the pins 28, which pass through the male and

female fastenings

23 and 25, and then raise the device therefrom by means of the handles 26.

In placing my device upon a car the upper portion is so set as to have the wheel 5 on a slight angle, as shown by dotted lines at min In this manner it will operate the switch no matter how close it is to the rail, and likewise when it is in position, as shown at y, which has just operated the switch in order to travel upon the track 31.

The operation of myinvention is as follows: hen the operator of the caris desirous of running his car over the straight track, he turns the lever 21, so as to place the wheel in the position as shown in Fig. 1 and at 00in Fig 1t. He then presses his foot upon the foot-lever 13, which brings the wheel in contact with the rail, when it strikes the switch, and because of its angle and incline it presses between the rail and switch thereby opening the same. hen the switch is in position for a straight run and it is desired to make the curve, the handle 21 is turned to the other side, which brings the wheel in the position as shown at 1 in Fig. 4, and likewise opens the switch, as therein shown, permitting the car to switch over the curve. Just as soon as the foot-pressure is released the tendencyof the spring 12 forces the device upward in its normal. position, which is entirely out of the way of any obstruction. If at any time the wheel should be a little out of place, the action of the spring 8 allows the wheel to adjust itself to the correct location.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1.
