FIRE-EXTINGUISHER FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 383,004, dated May 15, 1868.

Serial No. 238,920. (No model.)

To all whom it may concern.-

Be it known that 1, GEORGE WV. OBORN, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Fire-Extinguishers for Railway-Oars, of which the following is a specilication, reference being had to the accompany ing drawings, in which Figure l is a sectional elevation of a car with my invention applied as in use. Fig. 2

f is a detail view of the tank, aircylinder, and

connecting-pipes. Fig. 3'is a section on line 3 3, Fig. 2; and Fig. 4 is a detail view.

The invention consists in connecting the stoves and lamps with a tank containing a tireextinguishing composition, the tank being in turn connected with the air-brake drum or cylinder by a valved pipe, so that when a car is derailed compressed air will be allowed to low from air-brake cylinder or drum into the tank and force the composition therefrom into the stoves and lamptlames and extinguish the ires and put out the lamps; and the invention consists in the various combinations and constructions, as will be hereinafter' fully described and claimed.

A represents a car of the passenger type, in the opposite ends of which are two stoves, B B, of any of the various styles.

C C represent the car-trucks, and D the airbrake cylinder or drum, from which a short pipe, d, extends, the said pipe having a valve, d', provided with a crank, d2.

E is the tank for containing the extinguishing composition, preferably in Huid form.V The tank E is located, as shown in the drawings, in the car above the window at about the center, and is connected with the pipe d by the pipe e.

F is a pipe extending longitudinallyoi` the car and having two depending branches, ff, one at each end, communicating with the in terior or respace of the stoves B. The pipe F is also provided with short tubesf, leading to the lampsNin the top of the car. The pipe F is connected with the tank by the short pipe e', having a spring-valve, e2, adapted to be operated by the force of the compressed air en tering the tank, and forcing the fluid out of the tank through said pipe e into the pipe F, and thence to the lires and lamps.

G are rock-shafts mounted on the underside of the car above the trucks, and each provided with a crank, g, betweenv its ends, extending toward the center of the car, and with oppositelyextending cranks g' at its ends.

H is a valvevoperating rod connected at its ends to the cranks g, and between its ends to the crank d2 ofthe valve d, so that when either rock-shaft g is turned it will pull the rod and open the valve d to admit the compressed air into the tank E.

J are the triggers depending from the cranks g', and extending down between the wheels of the trucks to points just above the rails, so that when a truck jumps the track the triggers will strike the rails and be forced upward, thereby rocking the shaft G and operating the rod H and the valve d', as above set forth.

In order that the rockshafts may be oper ated from within the car, should occasion require, one or more of the cranks gare provided with hand-lifts G', which extend up through the door of the car, and by pulling which the rockshafts will be turned to draw the valverod H.

L is a section of hose connected with the tank E, so that should the car take ire from the lamp the tire may be extinguished by pulling on the hand-lift G. The compressed air will force the Iire-extingnishing liquid from the tank E through the said hose.

It will be understood that the tank E may be located in any suitable part of the car, and that I do not limit myself to the exact mechanisni shown in the drawings, as the same may be varied somewhat without departing from the spirit of my invention.

Any suitable chemical re extinguishing material may be used in the tank.

Having thus' described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a iireextinguisher for cars, of a compressed-air receiver with a tank for containing a tireextinguishing material,and having an outlet and an outward-open ing spring-pressed valve therein, and a pipe leading from the compressed-air receiver to IOO 2. The combination, in a fireextinguisher for cars, with the air-brake system applied thereto, of a tank for containing a {ire-extinguishing material and provided with an olit- 5 let in its bottom, an outward-opening springseated Valve therein, a pipe connecting the upper part of the tank with the compressedair supply of the brake system, and a valve in said pipe, substantially as set forth.

1o 3. rlhe combination, in a tire-extinguisher for cars, with air-brake mechanism, ofthe fireextinguishing mechanism, a valved pipe leading from the airbrake cylinder to the lire-extinguishcr, the rock-shafts G, having cranks [5 g and end cranks, g', the triggers J, depending from cranks g down between thewheels of the trucks, the hand-lifts G', extending p through the floor of the car, and the rod H, connected at its ends to cranks g and between its ends 2o to the valve in the said valred pipe, substantially as set forth.

4. In a tire-extinguisher for cars, the combination of the air-brake mechanism, the tank E, having the outlet cin its bottom, thedownward-opening valve e2 therein, a spring for 25 closing said valve against the pressure of the normal contents of said tank, the pipe F, eX- tending from end to end of the car and having branches leading to the stoves and to the lamps, and a hose connected directly to the 3o tank, with a pipe for conducting the compressed air from the brake mechanism into the top of the tank, whereby the extinguishing material will be forced by the full power of the compressed air through the pipes to the 35 Stoves and lamps or through the hose, substantially as set forth.

GEORGE W, OBORN.
