Year: 1867

page_text: LETTERS PATENT to Joseph Jones, of Little Bolton, in the County of
Lancaster, for the Invention of "AN IMPROVED CHEMICAL MIXTURE OR
COMPOUND FOR EXTINGUISHING FIRES AND DESTROYING EXPLOSIVE FIREDAMP
IN COAL MINES."
Sealed the 28th January 1868, and dated the 30th July 1867.
PROVISIONAL SPECIFICATION left by the said Joseph Jones at the Office
of the Commissioners of Patents, with his Petition, on the 30th July
1867.
I, JOSEPH JONES, of Little Bolton, in the County of Lancaster, do hereby
declare the nature of the said Invention for "AN IMPROVED CHEMICAL MIXTURE
OR COMPOUND FOR EXTINGUISHING FIRES AND DESTROYING EXPLOSIVE FIREDAMP IN
COAL MINES" to be as follows:-
I take oxides of manganese, iron, soda, potash, carbon, or any other oxides;
muriatic or chloric acid, or such substances of which these are composed or
produce; caustic liquor, iron, or any other caustic; ammonia, lime, or any.
other alkali mixed in a suitable quantity of water. I select one or more of
the said substances in quantities of each as circumstances may require for
extinguishing any particular kind of fires, such as cotton or other mills, or
buildings, oil warehouses, gunpowder magazines, and for destroying explosive
firedamp in coal mines.
For extinguishing fire in cotton or other mills I take the proportions as
follows: About three parts of oxides, seven parts of muriatic or chloric acid,
two parts of caustic, eight parts of ammonia, lime, or other alkali, one and a
Price 8d.1

page_text: half pounds of that mixture in two gallons of water; these proportions are
sufficient for an ordinary fire. But for destroying firedamp steam must be used
instead of water, and indeed steam may be used for ordinary fires instead of
water where it can be conveniently had. The said proportions may be varied
according to the intensity of the fires to be extinguished or the damp to be
destroyed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Jones in the Great Seal Patent Office on the 30th
January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
JONES, of Little Bolton, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of July, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Jones, Her special license, that I, the said Joseph Jones, my
executors, administrators, and assigns, or such others as I, the said Joseph
Jones, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time, and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED CHEMICAL MIXTURE
OR COMPOUND FOR EXTINGUISHING FIRES AND DESTROYING EXPLOSIVE FIREDAMP IN
COAL MINES," upon the condition (amongst others) that I, the said Joseph
Jones, my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Joseph Jones, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
I take cyanides and oxides of manganese, magnesium, iron, sodium,
potassium, carbon, or any other oxides or cyanides, muriatic acid, chloric

page_text: acid, sulphuric acid, nitric, carbonic, acetic, or any other acids, caustic liquor,
caustic soda, caustic lime, iron, copper, potass, or any other caustics,
ammonia, lime, soda, carbon, potass, or any other alkalies, or what these
separately or together are composed of or produce whether they be gases,
liquids, or solids, mixed in a suitable quantity of water; I select one or more
of the said articles in quantities of each as circumstances may require for
extinguishing any particular kind of fires, such as cotton or other mills,
buildings, or materials, oil warehouses, gunpowder magazines, Greck fire, fires.
of sulphur and sulphurous in the process of melting metals, and for destroying
explosive firedamp in coal mines, or for preventing combustion of the various
aforesaid inflammable materials. I keep the aforesaid articles separate from
each other and from water by means of separate vessels, distinct compart-
ments, or by any other means till used or required for use.
For extinguishing fires in cotton or other mills I take the proportions as
follows: I use about three parts oxides and cyanides, seven parts acids, two
parts caustics, eight parts of ammonia, lime, or other alkalies, I mix about
one pound and a half of that mixture in two gallons of water; these pro-
portions are about enough for an ordinary fire. But for destroying firedamp
steam must be used instead of water, and indeed steam may be advantageously
used for ordinary fires instead of water where it can be conveniently had.
The above-mentioned proportions may be varied according to the intensity of
the fires to be extinguished or the firedamp to be destroyed, and the chemical
mixtures before enumerated may be used by themselves without the admixture
of water or steam when desired.
In witness whereof, I, the said Joseph Jones, have hereunto set my hand
and seal, this Twenty-fourth day of January, in the year of our Lord
One thousand eight hundred and sixty-eight.
