IMPROVEMENT INV FIRE-EXTINGUlSHERS.

Specification forming part of Letters Patent No. 165,627, dated Octoberlll, 1875; application tiled March 18,12%. ,A

To all whom it may concern Be it known that I, PHILANDER M. DOUGH- TY, ot' Louisville, in the county of Jei'erson and State of Kentucky, have invented certain new and useful Improvements in Fre-Extinguishers; and I do hereby declare that the following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompany ing drawings and to the letters Vot` reference marked thereon, which form a part of this specication..

The nature of my invention consists in the construction and arrangement of a chemical nre-extinguisher, as will he hereinafter more fully set forth.

In the annexed drawing, Figure l is a longitudinal section of my reeextingnisher, and Fig. 2 is an enlarged section ofthe lid of the tank with the devices attached thereto.

` Arepresentsthe tank ofmy fire-extinguisher, constructed ol'anysuitable material and of any desired form and dimensions, whether portable or to be mounted on wheels. The bottom B ot' the tank is made funnel-shaped, andtrom its center extends the outlet-pipe C through the side of the tank. In this pipe is arranged a A stopcock, a, and a exible hose, D, with nozzle, is connected thereto in the usual manner.

The upper end of the tank is entirely open, and

provided with a lid or cover, E, which may be hinged or otherwise jointed to the tank on one side, and, when closed, is fastened thereto by any suitable means. The upper edge of the tank and lower edge of the lid are constructed to receive and hold packing b, ofrubber or other material, so that when the lid is closed a perfectly gas and water tight joint will be formed. By means ofthe lid E the ent-ire upper end of the tank A maybe thrown open, so as to facilitate thelling and reillingof the tank in whatever place the same may be. To the under side of the lid E are attached two bottles or receptacles, G G, ot' any suitable material, for containing the acid and soda. rlhe lower ends ot' these bottles are open and provided with flaring mouths, whichvare closed by Stoppers H H, made of rubber or other suitable material,'and each provided with a metallic disk,

d, on its upper or inner side. On the outer or lower side ot' each stopper H is an eye, e, through whichpasses the end ot' a rod, la, the other end of said rod passing through the eye on the' A other stopper. vFrom the center of therrod h another rod,I, extends upward through a central tube, m, attached in the lid E. To the rod l is fastened a tube, n, which is open at its upper end and surrounds the tube m, the upper end of the exterior tube n pressing against a packing-ring,p, when the stoppers are in place. On the upper end of the rod I is a knob, J, between which and the upper end of the tnbem is a spiral spring, s, surrounding the rod I, which spring holds the Stoppers tightly in their respective bottles. The bottles Gr G are lilled when the lid E is thrown open, and the stoppers then putin their place. The tank A is lled with water and the lid E closed, when the machine is ready for operation.

When it is desired to use the machine it is only necessary to press down upon the knob J, when the rod h will at once remove the stoppers from the bottles; and said stoppers being, by their eyes e, hung on said rod, they will turn and hang in the position indicated by dotted lines in Fig. 2. The soda and acid are thus simultaneously precipitated into the water, and generating carbonio-acid gas, so that by opening the stop-cock a the water and gas will be forcibly ejected from the tank.

It will be observed that the three elementswater, soda, and acid-are kept entirely separate until needed for use, which is ot great importance for many reasons. The water, being alone in the tank, will not corrode the stop-cock a, no matter how long it stands therein,which is always the case when the soda is held in a more or less perfect solution in the water. Gold water will not properly dissolve the sodaJ 5; hence the full ett'ect can never be obtained. By precipitating the soda and acid at one time into the water, the acid will heat the water and also create an agitation therein, thereby taci l-itatin g the dissolution ofthe soda, so that the full efiects of the soda and acid are obtained..

A latch, L, may be arranged on the lid to lock the rod I, to prevent the accidental removal ot' the stoppers H. I

rlhe object of the funnel-shaped bottom is to concentrate-the pressure, so that the liquid cnn be thrownrto a greater distance by the use 'of'said bot-'tom than by any other kind.

' obtained in other machines, owing to its coming Ainto contact with the bulk of' the soda, thereby producing-the greatest possible commotion, thus sending the acid, as also the soda,

Y Vinstantaneouslyin' every directionthrough allY parts of the machine, producing the best results possible to. obtain.

` Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. 'Iphe tank A, provided with funnel-shaped bottom B and outlet-pipe G, with stop-cock a, as and for the purposes herein set forth.-

2. The combination of the stoppers H, with eyes e, rods h I, tubes m n, packing p, knob J, and spring s, all constructed substantially as and for the purposes herein set forth.

3. .The tank A, in combination with the hinged cover E, provided with bottles for the soda and acid, the said cover being arranged to open and uncover the entire top of the tank, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.
