IMPROVEMENTS IN THE MANUFACTURE OF SOAP
Year: 1853

page_text: LETTERS PATENT to George Fergusson Wilson, of Belmont, Vaux-
hall, Managing Director of Price's Patent Candle Company, for
PROVISIONAL SPECIFICATION left by the said George Fergusson
Wilson at the Office of the Commissioners of Patents, with his
Petition, on the 10th October 1853.
I, GEORGE FERGUSSON WILSON, of Belmont, Vauxhall, Managing
"Director of Price's Patent Candle Company, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
SOAP" to be as follows:-
In the manufacture of soap cocoa nut oil has in some cases been
employed, but its more general use has been retarded by its smell being
perceivable in the soap, particularly when being used. Now my In-
vention consists of refining cocoa nut oil so as to deprive it of its
peculiar smell, or for the most part to do so before using it in the
manufacture of soap; for this purpose I prefer to subject the cocoa
nut oil, or its stearine or oleine, to the action of an alkaline agent,
and having deprived it of smell or refined it, I employ the product in
the manufacture of soap, in place of using cocoa nut oil in its crude
state, and the stearine of cocoa nut oil separated from the oleine by.
pressure may with advantage be used without further refining.

filed by the said George Fergusson Wilson in the Great Seal
Patent Office on the 10th April 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GEORGE FERGUSSON WILSON, of Belmont, Vauxhall, Managing Director
of Price's Patent Candle Company, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of October, in the year of
our Lord One thousand eight hundred and fifty-three, in the seventeenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said George Fergusson Wilson, Her special licence
that I, the said George Fergusson Wilson, my executors, administra-
tors, and assigns, or such others as I, the said George Fergusson
Wilson, my executors, administrators, and assigus, 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 "IMPROVEMENTS IN THE MANUFACTURE OF SOAP," upon the
condition (amongst others) that I, the said George Fergusson Wilson,
by an instrument in writing under my hand and seal, should particu-
larly 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 George Fergusson Wilson, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and-ascer-
tained in and by the following statement thereof (that is to say):
In the manufacture of soap cocoa nut oil has in some cases been
employed, but its more general use has been retarded by its smell being
perceivable in the soap, particularly when being used. Now my In-
vention consists of refining cocoa nut oil so as to deprive it of its peculiar
smell, or for the most part to do so before using it in the manufacture

page_text: of soap; for this purpose I prefer to subject the cocoa nut oil, or its
stearine or oleine, to the action of an alkaline agent, and having
deprived it of smell or refined it, I employ the product in the manu-
facture of soap, in place of using cocoa nut oil in its crude state, and the
stearine of cocoa nut oil separated from the oleine by pressure may
with advantage be used without further refining.
Having thus stated the nature of my said Invention, I will proceed
to describe the manner of performing the same.
To each ton of cocoa nut oil when melted I stir in nine gallons of
a solution of caustic soda, specific gravity 1150, and raise the tempe-.
rature to about 150° Fahrenheit, which I prefer to do by steam in an
external casing to the vessel employed. The oil is then allowed to cool
and settle for about twelve hours, and it will then be ready for use in
the ordinary manner of soap making when using cocoa nut oil. If
the cocoa nut oil has been subjected to pressure, and the stearine only
is to be used, it may be subjected to similar alkaline treatment, but
generally it does not require more purifying than may be obtained by
boiling it with free steam for about an hour; the stearine may be then
used in the ordinary manner of soap making.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that
what I claim is, employment of purified cocoa nut oil, and also of
stearine of cocoa nut oil, in the manufacture of soap.
In witness whereof, I, the said George Fergusson Wilson, have
hereunto set my hand and seal, this Eighth day of April, in the
year of our Lord One thousand eight hundred and fifty-four.
