METHOD OF .EXTINGUISHING FIRES.
Patented June 12,1877.
UN TED STATES cHARLEs M. MARTIN,
PATENT QFFIGE.
OF NE YO K, N. Y.
IMPROVEMENT m METHODS OF sx'rmeuisume FIRES.
Specification forming part of Letters Patent No. 191,872, dated June 12, 1877 application filed March 7, 1877.
To all whom it may concern it known that I, GHARLEs M. MARTIN, of the city and State of New York, have invented a new and improved Method ofExtinguishing Fires; and I hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the acpanying drawing.
Heretofore many methodshave been innse for utilizing carbonic-acid gas in the. extinguishing of fires, 'ad vantage being taken of its well-known quality of not supporting combustion. The simple generation of the gas and its conduction in volume-to the point of combustion is liable to be seriously disturbed by any and all rapidly-movin g currents, which are necessarily incident upon all conflagration. The discharge of water impregnated with carbonicacid gas by means of pressure generatedby' the production of such gas by chemical reaction in the vessel containing the water is well known; but muchof the gas mechanically entangled in the stream projected, the expulsion being equal in all directions, escapes and passes off before reaching the fire to be extinguished, and hence is not utilized. In such instances two agencies combine toward effecting the extinguishment of the fire, viz: first, the'automatic propelling force of the created gas projecting the water and, second, by the limited quantity of gas remaining entangled in the stream of water thrown, serves to cut off the atmospheric air and retard combustion.
described in Letters Patent No.-182,508, dated September 19, 1876, and consisting of a mixture of calcium, chloride, alum, having a potash base, and water, whereby I am enabled by the former to project a stream of the latter compound, and in the event of an exhaustion of the former, the latter may still be automat ically used to a greater or less extent in the extin'guishment of the fire.
In the said drawings, A is a gas-generating device, provided with means for generating gas. I prefer to use such as are covered in {fingers Patent No. 137,330, dated April 1,
B is a tank to hold any chemical compound especially adapted to the extinguishment of fires by means of its compound ingredients. For instance, such as is shown and described in Letters Patent No. 182,508, dated September 19, 1876.
These two tanks arejoined by means of a pipe, 0, having one end connected with the gas-space of tank A, and the other end leading to the top of the tank B containing the chemical mixture.
At the bottom of tank B is a tap, a, fitted with a coupling to receive a hose, 0. The top of tank B is provided with a screw-cap and nipple, for the purpose of introducing the chemical compound.
It is evident that any gas-generator may be used, and any chemical nongaseous fire-extinguishing compound may be used without departing from the spirit of my invention. 7
claim as new, and desire to secure by Letters Patent, is-
The method of extinguishing fires herein described, consisting in projecting upon the fire an extinguishing compound having a low propulsive power, by means of a fire-extinguishing gas having ahigh propulsive power, substantially as and for the purpose set forth.
