page_text: LETTERS PATENT to Osmund Williams, of Dursley, in the County of
Gloucester, for the Invention of "AN IMPROVED MIXTURE OR LIQUID FOR
EXTINGUISHING FIRE, APPLICABLE ALSO FOR PREPARING OR SATURATING VARIOUS
KINDS OF MATERIALS AND FABRICS, FOR THE PURPOSE OF RENDERING THE SAME
NON-INFLAMMABLE."
Sealed the 31st December. 1861, and dated the 5th July 1861..
PROVISIONAL SPECIFICATION left by the said Osmund Williams at the
Office of the Commissioners of Patents, with his. Petition, on the 5th:
July 1861.
I, OSMUND WILLIAMS, of Dursley, in the County of Gloucester, do hereby
declare the nature of the said Invention for "AN IMPROVED MIXTURE OR LIQUID
FOR EXTINGUISHING FIRE, APPLICABLE ALSO FOR PREPARING OR SATURATING VARIOUS
KINDS OF MATERIALS AND FABRICS, FOR THE PURPOSE OF RENDERING THE SAME
NON-INFLAMMABLE," to be as follows:-
This Invention consists in mixing with hot water by preference the following
ingredients, matters, or substances, in the following proportions:-To every
thousand gallons of water I mix about two thousand pounds of the soda of
commerce; six hundred and sixty pounds of the alum. of commerce, five
hundred and seventy pounds of roach alum (or mineral salt), one thousand

page_text: seven hundred and fifty pounds of common salt, two hundred and fifty pounds
of borax, thirty gallons of oil of vitriol, and seventeen pounds of chloride of
zinc. The borax, vitriol, and chloride of zinc do not require to be used in the
manufacture of the mixture to be employed for extinguishing fire, but are only
intended to be used in combination with the other above-named ingredients in
the manufacture of the mixture to be employed for preparing or saturating
timber, paper, and other inflammable substances, and also woven and felted
fabrics and tissues. The liquid used for the extinguishing of fire is as fluid in
the coldest weather in winter as in the warmest weather in summer. The
specific gravity of the above ingredients when mixed with one thousand gallons
of water, in addition to the extra weight of the water, is nearly five thousand
pounds, thus ensuring the certain deposition of the mixture when thrown
on a burning mass, and effectually extinguishing same in a short space
of time.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Osmund Williams in the Great Seal Patent Office on the
4th January 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, OSMUND
WILLIAMS, of Dursley, in the County of Gloucester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of July, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Osmund Williams, Her special licence that I, the said
Osmund Williams, my executors, administrators, and assigns, or such others
as I, the said Osmund Williams, 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 MIXTURE OR LIQUID FOR EXTINGUISHING FIRE, APPLICABLE ALSO
FOR PREPARING OR SATURATING VARIOUS KINDS OF MATERIALS AND FABRICS FOR THE
PURPOSE OF RENDERING THE SAME NON-INFLAMMABLE," upon the condition
(amongst others) that I, the said Osmund Williams, my executors or
administrators, by an instrument in writing under my, or their, or one of

page_text: their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per:
formed, 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 Osmund Williams, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, that is to say:
This Invention consists in mixing with hot water (by preference) the
following ingredients, matters, or substances, in the following proportions :-
To every
thousand gallons of water I mix about two thousand pounds of the
soda of commerce, six hundred and sixty pounds of the alum of commerce,
five hundred and seventy pounds of roach alum (or mineral salt), one thousand
seven hundred and fifty pounds of common salt, two hundred and fifty pounds
of borax, thirty gallons of oil of vitriol, and seventeen pounds of chloride of
zinc. The borax, vitriol, and chloride of zinc do not require to be used in the
manufacture of the mixture to be employed for extinguishing fire, but are
only intended to be used in combination with the other above-named
ingredients in the manufacture of the mixture to be employed for preparing or
saturating timber, paper, and other inflammable substances, and also woven and
felted fabrics and tissues. The liquid used for the extinguishing of fire is as
fluid in the coldest weather in winter as in the warmest weather in summer.
The specific gravity of the above ingredients when mixed with one thousand
gallons of water, in addition to the extra weight of the water is nearly five
thousand pounds, thus ensuring the certain deposition of the mixture when
thrown in a burning mass, and effectually extinguishing same in a short spaco
of time.
Having now fully described and set forth the nature and object of the said
Invention of "An Improved Mixture or Liquid for Extinguishing Fire, appli-
cable also for Preparing or Saturating various Kinds of Materials and Fabrics,
for the Purpose of Rendering the same Non-inflammable," together with the
best means I am acquainted with for carrying the same into practical effect, I
would remark, in conclusion, that I do not intend to limit or confine myself to
the precise proportions of the above-mentioned ingredients, matters, or sub-
stances herein described; and I hereby declare my Invention to consist in, and
I claim combining into a mixture water, soda of commerce, alum of commerce,
roach alum (or mineral salt), common salt, borax, oil of vitriol, and chloride

page_text: of zinc, and the use and application of said mixture for extinguishing fire, and
for rendering materials and fabrics non-inflammable, as above stated.
In witness whereof, I, the said Osmund Williams, have hereunto set my
hand and seal, this Thirtieth day of December, in the year of our
Lord One thousand eight hundred and sixty-one.
OSMUND WILLIAMS. (L.s.)
