APPARATUS FOR EXTINGUISHING FIRE. IN RAILWAY-CARS.

SPECIFICATION forming part of Letters` Patent No. 267,667, dated November 21, 1882.

' Application led June 28, 1882. (No model.)

To all whom it may concern:

Be it known that we,'MARCUs BROGKWAY and CHARLES N. WATTS, of Jamestown, in the county of Chautauqua and State of New York, have invented new and usefullmprovements in Apparatus for Extinguishing Firein Railway-Gars, of which the following is a specification.

This invention has for its object to provide means whereby the fire` in car-stoves can be quickly extinguished, in case of an accident to the train, to prevent the lire of the stove from igniting `the surrounding woodfwork of the car, and also to provide means whereby the lamps can be extinguished at the same time.

Our invention relates more particularly to a device in which the compressed air provided for operating the air-brakes is utilized in accomplishing these results; and our invention consists principally in combining with a carstove a water-reservoir holding a sufficient quantity of water to extinguish the fire in the stove, and connected with the tire-pot of the stove by a suitable conduit, and to which airpressure can be applied from the brake-pipe, so as to drive the waterfrom the water-reservoir into the tire-pot of the stove when the fire is to be extinguished; also, in combining with the. brake-pipe and water-reservoir an intermediate airlreservoir capable of holding a suflicient volume of air under pressure to drive the water from the reservoir into the stove; also, of mechanism whereby the air-pressure is applied automatically to the water-reservoir when the running-gear assumes an improper position with reference to the car-bodyfor instance, by one or more wheels leaving the rails; also, of mechanism whereby the airpressure can be applied to the lamps so as to extinguish the light; and, finally, of various details of construction, as will be hereinafter fully set forth.

1n the accompanying drawings, consisting of two sheets, Figure 1 represents a sectional elevationof our improved extinguisher. Fig. 2 is a sectional elevation of one end of a railway-car to which our improved extinguisher is applied. Fig. 3 is a fragmentary cross section of the car,

Like letters of reference refer to like parts in the several figures.

A represents the'iioor of an ordinary railway-car; A the roof, A2 the sides, and A3 one of the ends, of the car.

B represents one of the trucks, of any ordinary construction, and b the pipe through which compressed air is supplied to the brakecylinders in a well-known manner.

C represents the car-stove, and l) a waterreservoir arranged `near the stove and connected with the lire-pot thereof by a pipe or conduit, c. The latterconnects with the lower endv of the water-reservoir D, so as to permit all the water contained in the latter to bedis# charged through the pipe cinto the fire-pot of thestove. The reservoir D is provided in its top with an opening, d, which is tightly closed by a removable screw-cap, d', or Ysome -other suitable device, and through which the reservoir can be filled with water. The reservoir is also provided with a water-gage, d2, which renders the height of water in the same visible, and a faucet, d3, whereby the water canbc drawn olf, when necessary.

E represents an air-reservoir, arranged pret'- erably below the water chamber D, andconnected with the brakepipe b by apipe, c. The latter is provided with a stop cock, e', below the reservoir E.

j' represents a check-valve, seated in th'e end of the pipe c within the reservoir E in suchV a Inanner that the valve will be lifted from its seat by the compressed air passing from the pipe into the reservoir, and will automatically seat itself and prevent the escape of the compressed airfrom the reservoirifthepipeeshould become injured, so as to permit the escape of the air therefrom, or if the stop-cock c should be inadvertently opened.

g represents a pipe which connects the airreservoir E with the water reservoir D, and which terminates in the latter above the water level, `to prevent the water from passing into the air-reservoir E and to deliver the air-pressure upon the surface of the water.

H is a three-way cock, arranged in the pipe g, between the reservoirs D and E, for controlling the admission of the compressed air from the air-reservoir E to the water-reservoir D.'

I represents an air-pipe extending from the casing o t' the three -way cock H through the car, preferably near the roof thereof, and provided with branch pipes k, which open in a downward direction into the chimneys of the lamps L, whereby the ear is lighted7 so that an aircurrent issuing from these branch pipes will reverse the air current in the lamps and extinguish the lights. The principal passage m of the three-way cock H is designed to communicate with the two parts of the pipe g on opposite sides of the three-way cock, and the lateral passage a of the three-way cock is, designed to communicate with the air-pipe I. In the normal position of the threeway cock H, which is represented in Fig. 1, the communication betweenthe air-reservoir E and the waterreservoir D and the air pipe I is broken, and the three-way cock maybe heldin this position by a suitable spring or weight, if necessary.

O represents an arm attached to the plug of the three-way cock, and p represents a rope or chain which extends from the end of the arm 0 downwardly through the car-iloor and to the truck or running gear, to which the chain is securely attached in such manner that the chain will permit all ordinary vibrations ofthe truck or running-gear without changing the position ofthe arm O, but that when the truck or running-gear changes its position with reference to the car-bod y considerably-as, for instance, when the running-gear leaves the track-such change of position in the runnin g-gear or truckframe will cause a pull on the chain p and draw the arm O downward until theplug ofthe threev way cock assumes a position in which the passages m and n of the three-way cock establish communication between the air-reservoir E and the water-reservoir Dand pipe I.

In making up a train of cars provided with our improvement, the Water-reservoirs D are iirst filled with water to theproper height and then 'tightly closed. After the cars have been coupled together and the compressed air has been admitted from the locomotive to the brake-pipe b, the stop-cocks e are opened, whereby the reservoirs E are charged with p compressed air under the pressure which exists in the brake-pipe. The pressure of the air is readily determined by pressure-gages, with which the air-reservoirs E may be provided. -Ai'ter the reservoirs E have been so charged, the stop-cocks are closed and the apparatus is ready for operation.` It' from any cause the truck or running-gear to which the chain p is secured should assume an abnormal position with reference to the car-body, the three-way cock H is opened, and the compressed air contained in the reservoir E is admitted to the reservoir D above the waterlevel, whereby the-water is quickly forced out ofthe reservoir D through the pipe c and into the lire-pot of the stove, whereby the lire is extinguished. A portion of the air contained in the reservoir E passes at the same time through the pipe I and its branch pipes Ic into the lamps, so as to extinguish the lights. In this manner the fire and lights are quickly extinguished in case of accident, and the danger ot' the cars taking dre from the stove or lamps is thereby avoided.

. It is obvious that in case of danger the fire and the lights can be extinguished by simply pulling on the chain p, so as to open the threeway cock H.

We claim as our invention- 41. The combination, with a car-stove and a pipe or vessel containing compressed air, of a water-reservoir having its discharge-pipe connecting with ear-stove, and means whereby the compressed air can be admitted to the waterreservoir, so as to force the water from the same into the stove for extinguishing the fire, substantially as set forth.

2. The combination, with a car-stove, a water reservoir having its discharge pipe connected with said stove, and a pipe or vessel containing air under pressure, of an airreservoir adapted to receive and hold a sufficient volume of air to expel the water from .v

3. The combination, with a car-stove, a water-reservoir having its discharge-pipe connected with said stove, and a pipe or vessel containing air under pressure, of an air-reservoir adapted to hold a sufficient volume of air toaexpel the water from the water-reservoir, and means whereby the compressed air is automatically admitted to the water-reservoir when the truck or running-gear assumes an abnormal position with reference tothe carbody, substantially asset forth'.

4. The combinatiomwith a car-lamp, of a vessel containing compressed air, a conduit leading from said vessel to the lamp, a valve whereby the flow of air from the vessel to the lamp is controlled, and means whereby the said valve is connected with the truck or runninggcar ofthe car and whereby the air is automatically admitted to the lamp, so as to extinguish the light when the truck or running-gear assumes an abnormal position with reference to the car-bod y, substantially as set forth.

5. The combination, with a car-stove and the brake-pi pe b, of an air-reservoir., E, waterreservoir D, connecting-pipe g, provided with a cock, H, water-discharge pipe c, and cord or rope p, whereby the cock H is connected with the running-gear or truck of the car, substantially as set forth.
