Year: 1852

page_text: LETTERS PATENT to George Fergusson Wilson, of Belmont, Vaux-
hall, in the County of Surrey, Managing Director of Price's
Patent Candle Company, for the Invention of "IMPROVEMENTS IN
"
Sealed the 17th January 1858, and dated the 1st November 1852.
PROVISIONAL SPECIFICATION left by the said George Fergusson
Wilson at the Office of the Commissioners of Patents, with his
Petition, on the 1st November 1852.
I, GEORGE FERGUSSON WILSON, of Belmont, Vauxhall, in the County
of Surrey, Managing Director of Price's Patent Candle Company, do
hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MANUFACTURE AND TREATMENT OF Oma" to be as follows:-
This Invention consists of causing Lambung nuts (the product, it is
believed, of the aleurites triloba tree of botanists) to be crushed or
ground, and then pressed by hot or cold pressure between suitable sur-
faces, thereby obtaining the valuable products, oil and oil cake, which
may be purified by acids, alkalies, or alkaline salts, and then used
oil

page_text: by itself or mixed with other vegetable or animal oils, according as the
combined oils are to be used for burning or lubrication.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Fergusson Wilson in the Great Seal
Patent Office on the 30th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GEORGE FERGUSSON WILSON, of Belmont, Vauxhall, in the County of
Surrey, Managing Director of Price's Patent Candle Company, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of November, in the year
of our Lord One thousand eight hundred and fifty-two, in the sixteenth
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, ad-
ministrators, and assigns, or such others as I, the said George Fer-
gusson 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 law-
fully 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 AND TREATMENT
OF OLLS," upon the condition (amongst others) that I, the said George
Fergusson Wilson, by an instrument in writing under my hand and
seal, 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 George Fergusson Wilson, do
hereby declare the nature of the said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof (that is to say):
This Invention consists of causing Lumbang nuts (the product, it is
believed, of the aleurites triloba tree of botanists) to be crushed or
ground, and then pressed by hot or cold pressure between suitable sur-
faces, thereby obtaining the valuable products, oil and oil cake, which
oil may be purified by acids and alkalies or alkaline salts, and then used
by itself or mixed with vegetable or animal oil, according as the com-
bined oils are to be used for burning or lubricating. And in order that
my said Invention may be more fully understood, and readily carried
into effect, I will proceed to describe the means persued by mc.
The best manner with which I am acquainted of carrying out this
my Invention is as follows:- After separating the Lumbang kernal
from the hard shell by which it is enclosed, I crush it by passing it
under edge stones, or between rollers or other suitable crushing ma-
chinery. I then press it to separate the oil from the cake. I prefer
to effect this in the following manner :-I spread about an inch in
thickness of the crushed cake on a mat manufactured of cocoa nut
fibre; I place another mat above, and then press in a hydraulic press
for about twelve hours at the temperature of the air. I then crush
or grind the cake, and then press a second time in a press, heated
by steam pipes or otherwise to about 150 degrees of Fahrenheit;
or stamper presses may be used, as in the well-known linseed oil
manufacture.
When the oil that runs from the press is to be used for the purpose
of burning in lamps, I prefer to purify it by boiling it up by free steam,
with about two per cent. of sulphuric acid, much diluted (say twenty
of water to one of acid, or I mix it with equal weights of cocoa nut,
oleine, or with other burning oils, and purify the mixed oils as above.
For lubricating purposes I prefer to agitate the oil with a solution of
caustic potash in the proportion of about two per cent. potash to the
oil, or I mix it with other neutral oils or oleine and purify them,
together with the alkaline solution, as above; or it may be used as it
runs from the press, unpurified.
Having thus described the nature of my said Invention, and the

page_text: manner of performing the same, I would have it understood that what
I claim is, the manufacture of Lumbang oil as herein explained.
In witness whereof, I, the said George Fergussion Wilson, have
hereunto set my hand and seal, this Twenty-ninth day of April,
in the year of our Lord One thousand eight hundred and fifty-
three.
Witness,
JNO. G. ALCOCK.
