Description
TED STATES PATE i OFFICE,
CHARLES J. STROSACKER, OF MIDLAND, MICHIGAN, ASSIGNOR TO THE DOW CHEMICAL COMPANY, OF MIDLAND. MICHIGAN, A CORPORATION OF MICHIGAN.
FIRE-EXTINGUISHIN G COMPOUND.
No Drawing.
SAGKER, a citizen of the United States, and'a" resident of Midland, county of Midland, and
- State of Michigan, have invented a new and useful Improvement in Fire-Extinguishing Compounds, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
The fire extinguishing properties of carbon tetrachlorid (COL) are Well known, and have resulted in the extensive use of this medium for the purpose stated, particularly for putting out fires of highly combustible materials, such as gasolene and the like. The carbon tetrachlorid, for convenience of use, is ordinarily placed in a cylindrical container provided with a piston adapting the device to be used as a squirt-gun whereby a stream of the liquid may be discharged onto the blaze, such liquid immediately vaporizing so as to form non-combustible fumes.
which will extinguish the fire much more effectively than water. It is of course essential to the successful use of the tetrachlorid I in this connection that it remain liquid at all temperatures which may be encountered in use, the underwriters having arbitrarily set such temperature at F.
Inasmuch as the tetrachlorid solidifies at a A ficulties.
The object of the present invention is to provide a fire extinguishing composition including carbon tetrachlorid, which will fulfil the foregoing requirements, and to this end said composition includes the ingredients hereinafter described and specifically pointed out in the claims.
The following description sets forth in detail one approved combination of ingredients embodying my invention, such dis- Specification of Letters Patent.

Application filed June 6, 1916. Serial No. 101,965.
closed means constituting, however, but one of various ways in which the principle of the invention may be used,
I have found that the addition of a small quantity (5% to 10%) of mono-halogen derivative of methane, proves entirely satis factory in all of the particulars indicated above, particularly monochlor-methane or methyl chlorid (CH CI), and monobrommethane or methyl bromid CH Br). These ingredients are both gaseous, at ordinary temperatures, the former boiling at a point considerably below zero and the latter at a point a few degrees above; both, however, are readily soluble in the liquid carbon tetrachlorid, and do not readily boil off.
As an example, I should state that the addition of approximately nine (9) per cent, by volume, of such monochlor-methane, or methyl chloridas it is also termed, will suffice to reduce the freezing point of carbon tetrachlorid. when admixed therewith, to 50 F.; while the admixture of a similar amount of monobrom methane will prove equally efi'ective in securing the desired result. Either of the named ingredients will readily mix with the tetrachlorid, and have, so far as observed, no detrimental effect on the latter either in respect to its fire extinguishing properties or otherwise.
It should also be noted, that both of the foregoing derivatives may be added to the carbon tetrachlorid, instead of only one, the aggregate amount of the admixture remaining approximately the same as before.
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the materials employed provided the ingredients stated by any of the following claims or the equivalent of such stated ingredients be employed.
I therefore particularly point out and distinctly claim as my invention 1. A fire-extinguishing compound including carbon tetrachlorid and a relatively small quantity of a mono-halogen derivative of methane admixed therewith,
2. A fire-extinguishing compound including carbon tetrachlorid and a relatively small quantity of monobrom-methane admixed therewith.
3. A fire-extinguishing compound including carbon tetrachlorid and approximately five to ten per cent., by volume, of monosmall quantity of monochlor-methane and brom-methane admixed therewith. monobrom-methane admixed therewith. 10
