:union THE WESTINGI-IOU'SE AIR O'E PENN- AUTOMATIC CUT-OUT FOR TRIP-VALVES.
y To all whom 'it may concern:
Be it known that I, IlowAnnH. Dawson, a citizen of the United States, residing at New York, in the county ot' New York and State of New York, have invented new and useful Improvements in Automatic Cut-Outs for Trip-Valves, of which the following is a specification.
This invention relates to trip valve mechanism for air brakes, and more particularly to such mechanism yas employed on cars or trains that operate over two or more sect-ions of track subjectto dilt'erent conditions, such as partly in a tunnel or subway, partly outside upon the surface, and partly upon an elevated structure. In this class of service it may be desirable to use automatic trip valve devices for venting the train pipe and applying brakes, over one section of the road as for instance, in the subway or on the elevated structure, while it might not be desirable to have such trip valve mechanism operating over another section, such as outside surface lines, on account of the liability of ice, snow, or other obstruct-ions along the track, causing undesired and troublesome applications ot the brakes.
My invention has for its object to overcome this difficulty, and to provide lmeans for automatically cutting the .trip valve mechanism into or out ot operation, as the train passes from one section of: track where its use is desired, to another where its use is not desired, and vice versa. For this purpose, I provide a controlling device adapted to cooperate with the trip valve mechanism located upon a car or other vehicle ot' the train, and operating in one position to cut the said mechanisminto operation, and in another position to render said mechanism inoperative, the controlling device being governed by suitable contacts located along the track at the desired points.
In the accompanying drawing: Figure l is a diagrammatic view illustrating one form of such controlling device with one set of track contacts; and, Fig. 2,' is a similar view illustrating the other set of track contacts for causing the shifting of the controlling device.
As shown in the drawing, the controlling device com )rises a valve 3 for o eninfr or v 7 5 1 closing communication through a branch 113e Ll leadmfr from the tram bra-ke )ne l 7 i e: l a 5, to the trip valve mechanism, G, together Specification of Letters Patent.

with electro-magnets or solenoids, 7 and 8, and suitableV circuits and contacts for shitting the valve from one position to the other. The contacts, 9 and ll, are located in the circuit with the solenoid, 7, and cooperate with one set of track contacts, 13, located at the desired point er points alo-ng the'road, while contact, l0,vv is connected in the circuit with solenoid, 8, and cooperates with the other set of track contacts, l2.
The trip valvemechanism, (i, is usually provided with a trip lever, I4, adapted to engage a track contact usually connected with the signal or other syst-em in order to open a vent valve to discharge air from the train pipe and apply the brakes in case the .motorman should run past a signal set at danger. As these trip levers are exposed to dirt, Sno-W, ice, and other obstructions along the track, many undesired applications of the brakes would he liable to occur upon outside surface road conditions. At the point where the track emerges from the sub-V way or other protected section, a track contact, l2, is located and engages contact 10 to complete the circuit and energize the solenoid Sito shift the valve or controlling device to its cut-out position, thereby rendering the trip valve mechanism inoperative. Other track contacts 13, are located at the entrance to the subway or protected port-ion of the road, and engage with the other contact 9 or 11, carried on the car to energize solenoid 7 and shift the cont-rolling` device or valve back to its open position to cut the trip valvev mechanism into operation again. By this means, the safety and advantages afforded by the trip valve mechanism may be obtained throughout the protected sec tions of the road, while the diiliculties and troublesome delays caused by undesired op eration of trips and consequent brake applications along the exposed surface sections of the road will be avoided.
It will be apparent that. various forms of automatic controlling devicesv cooperating with suitable track contacts for cutting the trip val/ve mechanism into or out ot operation may be devised without departing Jfrom my invention. f
Having now described my invention, what I claim as new and desire to secure by Letters Patent, isz- 1. The combination with a train brake pipe and a trip valve mechanism for venting air therefrom to cause an application of brakes, of track contacts and an automatic controlling device, governed by said contacts for cutting said trip valve mechanism out of operatio 2. The combination with a train brake pipe and a trip valve mechanism Jfor venting air therefrom to cause an application of brakes, of an automatic controlling device' for cutting the trip valve mechanism into or out of operation, and track contacts for governing said controlling device.
3. The combination With a train brake pipe and a trip valve mechanism for venting air therefrom to`apply brakes, of a controlling valve for cutting out said trip valve mechanism, track contacts, and means governed by said track contacts for operating said controlling valve.
4. The combination with a train brake pipe and a trip valve mechanism for venting air therefrom to apply brakes, of a con-V trolling valve for cutting out said trip valve mechanism, electrical means for shifting said controlling valve, and track contacts for governing the electrical means.
5. The combination with a train brake pipe and a. 'trip valve mechanism for venting air therefrom to apply brakes, of a controlling valve for cutting out said trip valve 3 mechanism, a solenoid for shifting said. con-v trolling valve, track contacts, and circuits governed by said contacts for energizing said solenoid.
(3. The combination with a train brake 3 pipe and atrip valve mechanism for discharging air therefrom to apply brakes, of a controlling device for cutting said trip valve mechanism into and out oi operation, track contacts, and electro-magnetic means governed by said track Acontacts for actuating said device.
