A communication from FELIX HIPPOLYTE MONMON, of Montreuil (Seine), in the
Republic of France, Civil Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
This Invention relates to an improved composition of matter to be used as a fire
extinguisher, and to which I give the name of "The Universal Extinguishing Fluid."
In the manufacture of this composition, I proceed by preference as follows:
In a closed boiler or retort of suitable form and material is heated a mixture of say
twenty pounds of vegetable charcoal with say twenty five pounds of commercial
sulphuric acid. The gaseous products of this operation consisting principally of
Sulphurous Anhydride and Carbonic Anhydrido, are carried from this retort through
a closed washing tank which may be heated to any required degree, and thence pass
into a closed receiver provided with rotary beaters and charged with say one hundred
and fifty pounds of liquid ammonia and about sixty gallons of water. In this receiver,
the flow of the gas and the action of the beaters are maintained for about four hours,
after which a quantity of about one hundred pounds of chloride of sodium is added to
the liquid, and the introduction of the gas and the action of the beaters are continued
for about four hours more. The resulting product which constitutes the extinguishing
fluid is then drawn off into suitable receptacles and stored for use.
This fluid may be applied to the fire either by simple aspersion (if close approach is
practicable,) or by projecting it thereon enclosed in its receptacle which, in this case,
should be of such a description as to open on its fall or burst under the action of the
beat. When the approachable distance too great to permit of its being so applied,
it may be thrown by a pump of any suitable construction, or otherwise projected on to
the fire.
It will be understood that the above mode of generating the sulphurous anhydride
is only indicated as an example, and may be replaced by any other known process, and
that in general the relative proportions of the ingredients are necessarily modifiable
according to their purity or density or to the degree of concentration desired in the
product. It will also be understood that the apparatus herein described may be
modified at will or replaced by any other arrangement of like nature.

jected on to the fire.
It will be understood that the above mode of generating the sulphurous anhydride
is only indicated as an example, and may be replaced by any other known process, in some
of which the carbonic anhydride is absent but may be added if required, and that in
general the relative proportions of the ingredients are necessarily modifiable accord-
ing to their purity or density or to the degree of concentration desired in the product.
It will also be understood that the apparatus herein described may be modified at will
or replaced by any other arrangement of a like nature.
Having now particularly described and ascertained the nature of the said invention,
as communicated to me by my foreign correspondent, and in what manuer the same
is to be performed, I declare that what I claim is :-
A fire extinguishing compound, obtained by saturating with sulphurous anhydride
(with or without addition of carbonic anhydride) a solution of ammonia and chloride
of sodium, substantially as herein set forth.
