, IMPROVEMENT IN'EXTINGUISHING? FIRES meulLomesgq Specification forming part of Letters Patent No. [73,987, dated February 22, 1876 application filed i January 20, 1876. i

To all whom it may concern I 'Be it known that I, STEPHEN, S. NEWTON,

, of Binghamton, in the county of Broome and apart of this specification.

The invention relates to the combination, with a supply-pipeand nozzle, or a series of supply-pipes and discharging-nozzles, arranged in the various rooms of a building, 'of an air-tight tank containing a supply of water and alkali, a bottle or other vessel containing acid, a valve for discharging the contents of the bottle into the airtight water-tank, and a device which shall be put into operation automatically by an increase of temperature of the air in the building, to open the valve of the acid bottle orreceiver, whereby carbonic-acid gas is generated inthe water-tank and deliv-.

, cred with the water through the dischargingnozzle. i

Having thus set forth the nature of my invention, I will proceed to describe different i 1 methods which I have adopted forca-rrying it into practice.

In Figure 1, A AKA .represent a series of supply-pipes, arranged in or upon the walls of a building, with one or more nozzles or sprinklers, a, in each room, or in as many rooms as may be desired. Under onearrangement each of these nozzle'sisto be provided with one of the usualcheck-valves, held closed "by means of an easily-fusible solder. As the construct-ion and operation 0t this class of valves is fully understood,no specific description of them needfbe given; but inpractice I prefer to use one patented to me in Letters Patent dated December 21, .1875. B is a water-tank, provided with an opening, B, through which to fill it, or it may be filled by means of a force-pump. Inpractice I prefer-the latter method. 0 is a receiving and supply tank, connected with tank B by a pipe,

11, having a cock, b. O is a pipe leading from in fire-extinguishers.

0 D is the acid bottle or receiver,.provided with an opening, d,'into the tank B. D is a valve-stem, carrying a valve, ti at its lower end, and working in a stnffing-hox, d ,'at the upper part of the bottle or acid receiver. d is an opening into the bottle. E is a lever, fulcrumed at c, and connected to the valvestcm D at c. F is an air-cylinder. F is a piston-rod,-carrying at the lower end a piston, F whichfits air-tight Within cylinder F. The piston-rod is secured to lever E, at e, by means of a set-screw,f.' f is a spiral spring surrounding the end of piston-rod F, one end of the spring resting against the lever E, the other end pressing against any suitable support. F is an air-pump.

proportion of soda to be varied according to i circumstances, butabout that commonly used the pipes A A A the valves of thenozzles being securely closed, until the piston]? and piston rod F are forced upward and the valve d 'is thrust firmly into the opening d. The

bottle is then filled with acid. As the pistonrod F is forced up the springf is'compressed. The tension thus produced by thisspring must be such as to insurethat it will overcome the p friction of the piston in the cylinder and elsewhere, and the weight. of the acid upon the valve, so that when the air-pressure within the pipeand upon the under side of the piston F is released, the spring will force the:

piston down,thus raisingvalve d, and peri .mitting the acid to enter and mix with the al- 11; isevident kaline water in the tank B.

that whenever-the temperature of the room in which oneof the nozzles is located is raised sufficiently to release easily-fusiblesolder, this opening of the valve al will takeplace, as will be readily understood without furtherexplanation.

' I do not wish to be limited to the use of the PATENT OFFICE the supply-pipe to tank 0. (l is a cock in pipe G cis a valve closing the end of pipe I The operation of these devices is as follows: I

Air is then forced into particular acid-bottle hereshown, nor to this As the purpose and operation of the receiving-tank (J, pipe 0 and the cock and valve attached thereto are fully set forth in my patent of December 21, 1875, it is not necessary to describe them in thispatent.

What I claim is The combination of the following elements, namely a series of supply-pipes and discharging-nozzles, which are closed by an casily-fusible solder, a tank containing an alkaline solution, an acid-bottle, an-airpump for compressing air within the supply-pipe, and a piston connected with the acid-bottle and with the supply-pipes, substantially as set forth, whereby, when the air-pressure'within the supply-pipes is released, the acid will be discharged into the alkaline solution.

In testimony that I claim the foregoing as my own I atfix my signature in presence of two witnesses. v
