JOHN PHILIP SCOTT, OF NEW YORK, N. Y.
CH'EMICAL EIRE-EXTINGUISHER.
SPECIFICATION forming part of Letters Patent No. 357,292, dated February 8, 1887.
Application filed July 7,1885. Serial No.170,857. (No model.) Patented in England September 15, 1855, No. 10,938; inBelgium September-'18, 1885, No. 70,243, and in France September 21, 1885, No. 171,263.
To aZZ whom it may concern.-
Be it known that I, JOHN PHILIP Soorrr, a citizen of the United States, and a resident of New York city,'in the county of New York and State of New York, have invented certain new and useful Improvements in Chemical Fire-Extinguishers, (for which I have obtained Letters Patent in England September 15, 1885,
No. 10,938; in Belgium September 18, 1885,
No. 70,243, and in France September 21, 1885, No. 171,263,) of which the following is a specification.
The object of my invention is to produce a chemical fire-extinguisher that shall be certain and quick in its operation and free from the various defects inherent in those in common use. For this purpose I place the antiphlogistic material, D, in a receptacle. (Shown at A in the accompanying drawings.) This receptaclc is made of glass or similar brittle material so thin, and consequently fragile, that the weight of the whole, if dropped about twelve inches (more or less) upon any ordinary substance-as a wooden floor or,tablewould a fire is once started therein it may spread very rapidly. In such cases a person naturally throws the fire-extinguisher directly at the flames, and in abale of loose cotton or lace even the thin bottle described above may fail to break in time for the most satisfactory results. For such cases I surround the bottle A with a ring, E, of iron or some other hard substance, which, being attached to the bottle by means of stays or guys e, of wire or cord, and held in position by the aid of light springs 6', will, when the bottle is thrown or dropped, come in contact with the bottle A and cause it to break at once, however soft the spot it may strike upon.
The material of which E is made may be of any form or proportion, and secured to the bottle in any manner; but I prefer the form and fastenings described above. K
The stays or fastenings e are made of wire, and so hooked and secured that the ring E may be removed, and they and the bottles packed' separately for transportation; and when arranged for use the rings may be attached to the bottles by simply twisting or tying the fastenings together.
The bottles should be kept thus prepared in the rack, ready for instant use.
v The extreme fragility of the bottle A renders it liable to be broken by the expansion and conversion into gases of itscontents,
caused by very slight changes in temperature, and in any ordinaryroom such bottles would burst and their contents be wasted. To obvi ate this difficulty I insert in the stopper B of the bottle a small open tube or safety-valve, O, which permits the escape of the surplus gas as generated slowly by slight changes of temperature, while the bore or vent c of the tube 0 is made so small that a sudden change. of several degrees in the temperature of the surrounding atmosphere-as in case of a fire commencing-will generate gas faster than the vent 0 can relieve the pressure thereof, and the receptacle will burst, although no one may be at hand to throw it, thus making an automatic or self-acting fire-extinguisher. The tube 0 might be incorporated or made in the material of A, but I find the stopper the most convenient place for it.
The tubeOis bent back upon itself at c and enlarged at 0 near the outer end.
In the accompanying drawings, Figure 1 is a vertical sectional view of a chemical fire-extinguisher with my improvements. Fig. 2 is a plan view showing the metal ring and connections. Fig. 3 is a detail of part of Fig. 1.
The same letters refer to the same parts throughout.
The neck of the flask A is enlarged for the reception of the stopper B and its cement,
forming a shoulder at a, so that on inserting the stopper it will hold it in such position that the mouth of the tube G will be flush, or nearly so, with the mouth of A, so that the bulb c and bend 0 may be bedded in the cement and protected thereby.
1. The combination, with a frangible receptacle adapted to contain liquid fire-extinguishing material, of a tube extending into the in- 3. In a chemical fire-extinguisher, the fragile receptacle A, containing the material D I and having the ring E, springs e, and guys 0' 15 so connected as to insure the breakage of A,
as herein shown and set forth.
Signed at New York, in the county of New York and State of New York, this 6th day of July, A. D. 1885.

terior of the receptacle and provided with a I twist or curl, wherebya circuitous communication is afiorded between the interior of the receptacle and the external atmosphere, substantially as set forth.
2. In a chemical fire-extinguisher, the general combination of the receptacle A, having a shoulder, a, the stopper B, the tube 0, with Vent 0, bulb 0", and bend a, and the material D, the whole constructed and operated subst antially as and for the purposes herein shown and set forth.
