Year: 1852

page_text: LETTERS PATENT to George Fergusson Wilson, of Belmont, Vaux-
hall, Managing Director of Prico's Patent Candle Company, for
the Invention of "IMPROVEMENTS IN THE PREPARATION OF MATERIALS
FOR AND IN THE MANUFACTURE OF CANDLES AND NIGHT LIGHTS."
PROVISIONAL SPECIFICATION left by the said George Fergusson
Wilson at the Office of the Commissioners of Patents, with his
Petition, on the 2nd November 1852.
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 PREPARATION
OF MATERIALS FOR AND IN THE MANUFACTURE OF CANDLES AND NIGHT
LIGHTS" to be as follows:-
This Invention consists of first separating the stearine of palm oil
from the oline, and acidifying and distilling the stearine, in place of
carrying on these processes on palm oil before separating, as heretofore.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Fergusson Wilson in the Great Scal
Patent Office on the 2nd May 1853.
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 Second day of November, in the year
of our Lord One thousand eight hundred and fifty-two, in the
sixteenth year of 1er reign, did, for Herself, 1er heirs and suc-
cessors, give and grant unto me, the said George Fergusson Wilson,
Her especial license that I, the said George Fergusson Wilson, my
executors, administrators, and assigns, or such others as I, the said
George Fergusson Wilson, 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 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 PREPARATION OF MATERIALS FOR
AND IN THE MANUFACTURE OF CANDLES AND NIGHT LIGHTS," upon the
condition (amongst others) that I, the said George Fergusson Wilson,
by an instrument in writing under my hand and scal, should particu-
larly describe and ascertain the nature of the said Juvention, 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):
This Invention consists of first separating the stearine of palm oil
from the oleine, and acidifying and distilling the stearine in place of
carrying on these processes on palin oil before separating, as heretofore.
And in order that my said Invention may be more fully understood, and

page_text: readily carried into effect, I will proceed to describe the means pursued
Heretofore it has been the custom to treat palm oil in its
natural state, by the well-known process of acidification by sulphuric
acid, and then to distill the same. I have found that it is very advan-
tageous to operate upon the harder parts of palm oil after the oleine or
more liquid part has been removed, in place of operating on the palm
oil in its crude state. In order to separate the oleine from the crude
palm oil I first heat it to about 212° of Fahrenheit by means of a coil
of steam pipe; I then let it cool gradually to allow crystallization to
take place. The palm oil is then subjected to pressure, which I prefer
to do by hydraulic presses, as is well understood when pressing palm
and other oils to obtain the stearine; I then acidify the stearine by
combining therewith sulphuric acid in like manner to that in which
crude palm oil has heretofore been acidified by the use of sulphuric
acid; I then cause the acidified stearine of palm oil to be distilled in
like manner to that in which acidified crude palm oil has before been
distilled by the aid of heated steam, as is now well understood; and I
would state that I make no claim to any of the above-named processes
separately. But what I claim is, the subjecting the stearine of palm
oil to the processes herein described.
In witness whereof, I, the said George Fergusson Wilson, have
hereunto set my hand and seal, this Twenty-ninth day of March,
in the year of our Lord One thousand eight hundred and fifty-
Witness,
