IMPROVEMENTS IN THE MANUFACTURE OF EFFERVESCENT BEVERAGES
Year: 1862

page_text: LETTERS PATENT to William Mangham, of Prospect Place, Wandsworth.
Road, in the County of Surrey, for the Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF EFFERVESCENT BEVERAGES."
Sealed the 23rd January 1863, and dated the 28th July 1862.
PROVISIONAL SPECIFICATION left by the said William Maugham
at the Office of the Commissioners of Patents, with his Petition, on
the 28th July 1862.
I, WILLIAM MAUGHAM, of Prospect Place, Wandsworth Road, in the County
of Surrey, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF EFFERVESCENT BEVERAGES," to be as follows:-
This Invention has for its object improvements in the manufacture of
effervescent beverages. For these purposes phosphate of soda (say, six drams)
is dissolved in about half a pint of water and is when in close vessels rendered
effervescent by carbonic acid gas which is combined with the solution either
by mechanical means or by decomposing a carbonated alkali in the liquid,
say, 2 scruples of sesqui-carbonate of soda or bi-carbonate of potash, a dram
of tartaric acid or citric acid being to effect the decomposition mixed with the
solution of phosphate of soda. Or such beverages may be produced by mixing
phosphate of soda (2 drams) and a carbonated alkali preferring sesqui-carbonate
of soda (2 scruples) and dissolving the same in water in an open vessel, and
then applying thereto a suitable acid, such as tartaric or citric acid
(a dram). The quantities above mentioned may be to some extent varied.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MAUGHAM, of Prospect Place, Wandsworth Road, in the County of Surrey
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of July, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Maugham, Her special licence that I, the said William
Maugham, my executors, administrators, and assigns, or such others as I, the
said William Maugham, my executors, administrators; and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF EFFERVESCENT BEVERAGES," upon the condition
(amongst others) that I, the said William Maugham, my executors or adminis-
trators, 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 William Maugham, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following"
statement thereof, that is to say :-
I dissolve phosphate of soda, preferring that commonly called phosphate or
rhombic phosphate of soda, at the rate of six drams troy, to half a pint
of water, and to render this liquor aërated it is only necessary to pass it into
a sufficiently strong and properly closed vessel, and then to charge it with
carbonic acid gas under a sufficient degree of pressure which may be varied
so as to be greater or less at the will of the manufacturer. I consider it
unnecessary to describe any particular form of apparatus for effecting this
object as the machinery employed for making soda water or other aërated
waters is all that is required to complete the operation in view, the pressure
being regulated by a pressure guage. I do not confine myself to the above

page_text: strength of solution of phosphate of soda in water. The water thus aerated
is then to be drawn off into proper bottles closed with corks tied down, and
wired as is well understood. Or to a solution of phosphate of soda of the
above named strength or of greater or less strength placed in bottles sufficiently
strong, I add two scruples of sesqui-carbonate of soda or of bi-carbonate of
potash and then from about half a dram to 35 grains of tartaric acid or citric
acid, corking the bottles rapidly with well and previously fitted corks before
decomposition has had time to take place between the carbonated alkali and
acid so that the solution may be under pressure of the carbonic acid, thus
liberated and retained in the bottle. This method is not so effective for
rendering the water effervescent as the method first described. Or I mix
together in a powdered state two drams of phosphate of soda and two scruples
of a carbonated alkali, preferring sesqui-carbonate of soda. When required.
to be taken in an effervescent state, it is only necessary to dissolve this mixture
in water, and then to add thereto from half a dram to 35 grains of tartaric acid
or citric acid. These ingredients for portability may be enclosed in separate"
papers as Seidlitz powders are sold.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood, that what I claim is the
employment of phosphate of soda in the manufacture of aërated water.
In witness whereof, I, the said William Maugham, have hereunto set
my hand and seal, this Twenty-eighth day of January in the year
of our Lord, One thousand eight hundred and sixty-three.
W. MAUGHAM. (L.8.)
