To all whom it mag concern: 7
Be it known that 1, CHARLES J. HURLEY, a citizen of the United States, residing at Sharon Hill, in the county of Delaware and State "ofPennsylvania, haveinvented cer tain new and useful. Improvements in Electrically-Controlled Train-Stopping Mecha nism, of which the following is a specification.
My invention relates to improvements in electrically controlled train stopping mechanism, the object of the invention being to provide improved mechanism on railway circuit is closed and the block not occupied.

ga A further object is to provide improvements of this character which will operate with block signaling mechanism, and not interfere with the ordinary train signaling systems in use.-
\Vith these and other objects in View, the invention consists in certain novel features of. construction and combinations-and arrangements of parts, as will be more fully hereinafter described. and pointed out in the claims. V
In the accompanying drawings; Figure 1,
A is a viewpartly in side elevation and partly movable plunger adapted to open the valve 2' and normally held in its lowered position 755 by means of a coiled springs. Part 2 illustrates diagrammaticallyan air brake valve,

but may also represent some means for communicating a signal to the engineer in the cab, and I would have it. understood that when I refer to train controlling mechanism l employ this language broadly to mean either brake applying means or sig naling means vfor the engineer.
5, is a vertically movable plunger which is mounted to slide in brackets 6 on support 1, and is normally held-in its lowest position by means of a coiled spring 7. The lower end of this plunger 5 is provided with a shoe 8 adapted to be elevated by a cam track 9, which latter in the electric circuit with the block. It may also be an electric circuit with any ordinary block signaling system of the closed circuit type. The upper end of plunger 5 is recessed as shown at 10 to receive a trip 11, said trip pivotally connected to an upwardly projecting lug 12 on plunger 5 by means of a pin 13, and the trip normally held in vertical alinement with the plunger by means of a small coiled spring 14:.
15, is'a bracket support fora horizontally movable pin 16, which projects into a recess 17 in trip 11, and is normally held in this position by meansoit' a spring 18. 19 is an electro-magnet which when the shoe 8 en gages the cam track 9, if the electric circuit of the block isclosed, will be magnetized so asto draw a. pivoted armature 20 toward the same. This armature 20 is connected by a link 21 with the pinlG, so that thepin 16 will be drawn out of the recess 17. One wall of this recess li' is in the form of a cam illustrated at 22, and the upper end of the cam wall 22, will cause the trip l'l to. pivot and move inwardly into the path of plunger 3, the lower end of the atter being notched as illustrated at to receive the end of the trip and be moved upwardthereby. When the pin. 15 is drawn out of the recess 17 by the electro-magnet 19, plunger 5 will be moved upward without engaging plunger 3, hence not operating the train stopping means. It will therefore be noted that if no train is on the block ahead, the normally closed circuit of the block will, when shoe 8 rides on track 9, energize the magnet. 19, causing it to draw back pin 16, and allowing the plung r 5 to move up withoiit stopping the train. If, however, a train occupies the block ahead, the circuit will be open, the magnet l9'will not be train controlling menus on the support, of n energized, the pin 16 will be in the recess 17 so as to pivot the trip 11, when plunger 5 moves upwardly causing the trip to engage in the notch 23 in plunger 3, and operate the train stopping means.
Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself'to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
Having thus described my invention, what I claim'as new and desire to secure by Letters Patent is:
1. -In a mechanism of the character-described, the combination with a support and train controlling means thereon, of a vertically movable plunger, a pivoted trip on the plunger, a cam track, a shoe on the plunger adapted to engage the cam track, and electric meansin circuit with said plunger and track, and adapted to control the movement of said trip whereby the trip may or may not operate the train controlling means, substantially as described.
2.-In a mechanism of the character described, the combination with a support and train controlling means thereon, of a vertically movable plunger, a pivoted trip on the plunger, a cam track, a shoe on the plun er adapted to engage the cam track, a movable pin adapted to be engaged by said trip to cause the same to rotate on its pivot so that it will engage the train controlling means, and an electro-magnet in circuit with said plunger and track and ada ted to move said pin out of engagement w1th the trip, substantially as described.
3. In a mechanism of the character de' scribed, the combination with a support and train controlling means on the support, of a vertically movable plunger, a shoe on the plunger, a cam track engaged by said shoe to move the'plunger vertically, but out of alinement with the train controlling means, a pivoted trip on the plunger, a pin adapted to be engaged by said trip to cause the same to rotate on its pivot so that it will engage the train contro ling means,-ancl an electromagnet for moving said pin, substantially as described.
4. In a mechanism of the character described, the combination with a support and vertically movable lunger, a shoe on the plunger, a cam tract engaged by said shoe vertically movable to move the lunger vertically, but outof alinement wit 1 the train controlling means, a pivoted trip on the plunger, a cam recess in said trip, a bracket on the support, a sliding spring-pressed pin in said bracketprojected into said cam recess of the trip to move the trip into position to engage the train controlling means, and an electro-mag net for moving said pin out of said recess, substantially as described.
5. In a mechanism of the character described, the combination with a support and train controlling means on the support, of a lunger, a shoe on the plunger, a cam trac to move the lunger vertically, but out of alinement wit the train controlling means,
of said recess, said train controlling means engaged by said shoe havin a notch in its lower end, and the u per end of said trip beveled whereby w en the trip is pivoted by the pin, it will move into the notch in the'train controlling means, substantially as described.
6.'In a mechanism of the character described, the combination with a support and train cont-rollin means on the support, of a vertically mova le plunger, a shoe on the plunger, a cam track engaged by said shoe to move the plunger vertically, but out of alinement with the train controlling means, I
a pivoted trip on the plunger, a cam recess in said trip, bracket on the support, a sliding spring-pressed pin in said bracket projected into sztid cam recess ofthe trip, an electro-magnetfor moving said pin out of said recess, sald train controllingmeans having a notch in its lower end, and the upper end of said trip beveled whereby when the trip is pivoted by the pin, it will move into the notch in the' train controlling means, springs normally holding said train controllin means and ,said plunger in their lowere d. positions, anda spring normally holding the trip in alinement with the plunger and out of the path of the train controlling means, substantially as described.
