SWITCH-OPERATING DEVICE.

To all whom it may concern.

Be it known that I, Tnorms H. LORD, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented a new and useful Switch-Operating Device, of which the following is a specification.

This invention relates to railway switches of that type designed to be operated by mechanism on a car approaching the switch.

The object of the invention is to provide depressible members adjacent opposite portions of the track at a point removed from the switch, said members being attached to the tongue so as to shift it and thus either open or close the siding, there being separately operated actuating shoes carried by the car for bearing upon these depressible members.

Another object is to provide separately movable actuating shoes designed to be operated by a single lever upon the car, said lever when swung in one direction actuating mechanism for shifting one of the shoes into operative position and, when swung in the opposite direction, serving to shift the other shoe.

WVith these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention is shown.

In said drawings :-Figure 1 is a side elevation of the apparatus embodying the present improvements, the positions of the parts, when one of the shoes is depressed, being indicated by dotted lines. Fig. 2 is a plan view of the switch and ,the mechanism connected to it. Fig. 3 is an enlarged section on line AB Fig. 1, the car mechanism being shown in elevation. Fig. 4 is a perspective View of the pivot portion of the lever and the guide therefor.

Referring to the figures by characters of reference A designates the rails of the main line, B the rails of the siding and C the pivoted switch tongue which is of the usual or any preferred construction. A cross-bar 1 is connected to the switch tongue and extends under both of the rails A, the ends of the bar pivotally engaging cranks 2. Each crank constitutes part of a rod 3 extending longitudinally beneath one of the rails A, the ends of the rod being journaled within Specification of Letters Patent.

hangers t and each rod being provided at that end thereof farthest removed from crank 2 with a crank 5 preferably located perpendicularly to the plane occupied by the crank 2. These rods 3 are preferably arranged within trenches 6 extending below the rails A, there being slots 7 in the tops of the trenches at those ends thereof farthest removed from the switch. Projecting into these slots are inclined contact arms 8 arranged outside of but close to the rails A and mounted upon the upper ends of stems 9 which are pivotally mounted on the cranks 5. The contact arms 8 are inclined up wardly and toward the switch so as to permit the actuating device hereinafter described to ride upwardly upon said arm without shifting it too violently. The various parts herein described are so arranged that when the tongue 0 is in one of its positions one of the contact arms 8 is elevated while the other arm 8 is in its lowest position. In other words, the two contact arms move downwardly alternately, the depression of one causing the switch tongue to shift in one direction while this movement of the switch tongue can be reversed by depressing the other arm. A guide flange 10 is arranged along the outer wall of each slot 7, and the free end of this flange is preferably flared laterally so as to guide the actuating means into contact with the contact arms.

The mechanism utilized for operating the contact arms is designed to be carried by a car D and consists of side hangers 11, each of which is braced by an inwardly extending web 12. A shaft 13 is journaled in the upper portion of one of these hangers and is provided at its ends with inner and outer crank arms lat and 15 respectively, there being a coiled spring connecting the crank arm 1 with the car structure as indicated at 16. An actuating shoe 17 is pivotally connected to the lower portion of the hanger 11 011 which shaft 13 is mounted and one end of this shoe is connected to the crank arm 15 by means of a link 18. The other end of the shoe is preferably formed with an upturned end 19 designed, when said shoe is actuated in one direction, to move against the contact arm 8 in the path thereof and force it downwardly to shift the switch.

A guide standard 20, preferably formed of spaced segmental plates as indicated in F 4, is mounted on the car structure, and fulcrumed within this standard is a secondary lever 21 the lower end of which is connected to crank 14 by means of a link 22. The upper portion of this lever is provided with a laterally extending lug or projection 23 disposed in the path of a main lever 2% fulcrunied within the standard 20. The lower end of this lever is connected by the link 25 to a crank arm 26 formed at the inner end of a shaft 27 journaled in the upper portion of the other hanger 11. A crank arm 28 is formed at the outer end of shaft 27 and is connected by a link 29 with a shoe 30 fulcrumed upon the lower portion of the hanger 11, said shoe being similar to the shoe 1'? hereinbefore described. A coiled spring 31 is secured to the web 12 of the hanger in which shaft 27 is journaled and said spring is attached to the lower portion of the main lever 24. It will be apparent therefore that the two springs cooperate to hold the main lever normally pressed against the stop lug 23 of the secondary lever 21.

If the switch tongue C is in the position shown in Fig. 2 and it should be desired to direct the car along the main track and not on to the siding, the operator on the car approaching the switch draws the main lever 2 1 toward him. Said lever will thus be moved away from contact with the lug or projection 28 and the lower end of said lever will pull on the crank 26 through the link 25 and thus cause the shaft 27 to be partly rotated. The outer crank 28 will therefore be elevated and will pull on one end of the shoe 30 through link 29. The other end of the shoe will be pushed downward so as to lap the outer face of the adjoining rail A, and when the car arrives at a predetermined position upon the track this depressed shoe will move against the inclined contact arm 8 and force it downwardly. The rod 3 will thus be partly rotated and the crank 2 at the switch end thereof will pull the tongue C laterally so as to close the siding. This operation will of course elevate the other contact arm 8. While said shoe 30 is being forced clownwardly the other shoe 17 remains practically stationary, because its actuating lever 21 is not operated. Should another car be ap proaching the switch and should it be desired to direct it on to the siding, the operator pushes forward on the main lever 24 so as to force it against the stud or projection 23. Movement will thus be transmitted to the secondary lever 21, and this in turn will transmit motion to the shaft 13 through link 22 and the crank arm 1 1. The crank arm 15 will therefore actuate the shoe 17 through the link 18 and said shoe will therefore be brought into position to contact with and depress the other arm 8 so as to shift the tongue 0 laterally and open the siding. During this movement of the shoe 1'? the other shoe 30 will be slightly elevated be cause the crank arm 28 and link 29 are normally arranged at such an angle to each other that when the-crank arm 28 is drawn downwardly the only movement imparted to the upturned end 19 of the shoe is in an upward direction to a slight extent. The springs 16 and 81 of course serve to automatically return the various parts to their initial positions subsequent to the actuation. of the switch.

It of course to be understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention. In order to pr-vent secondary lever 21 from swinging in one direction a stop projection is foaned within the standard and projects into the path of said lever, said projection however being of such size as to permit the main lever 24: to pass it.
