CERTAIN IMPROVE- MENTS IN TREATING OIL OF COLZA AND SIMILAR OILS."
Year: 1852

page_text: LETTERS PATENT to Alexandre Deutsch, Manufacturer, of Paris,
in the French Empire, for the Invention of "CERTAIN IMPROVE-
MENTS IN TREATING OIL OF COLZA AND SIMILAR OILS."
PROVISIONAL SPECIFICATION left by the said Alexandre
Deutsch at the Office of the Commissioners of Patents, with
his Petition, on the 23rd December 1852.
I, ALEXANDRE DEUTSCH, do hereby declare the nature of the said
Invention for "CERTAIN IMPROVEMENTS IN TREATING OIL OF COLZA AND
SIMILAR OILS" to be as follows:-
I introduce oil of colza or other similar oil into a pan or boiler
placed over a fire, or surrounded by a steam jacket, or otherwise
heated, and I heat or boil the oil for several hours. A scum or
spongy foam collects on the surface of the oil, and the heat is continued
until this scum diminishes and subsides to the bottom of the boiler.
The application of heat is then discontinued, and the oil is left to
settle for a day or two, and then drawn off. Oil of colza or other
similar oil thus treated is better adapted than before such treat-
ment for being employed in the manufacture of wool, and for the
lubrication of machinery. It may be used alone, or with the addi-

page_text: tion of a solution of caoutchouc or other substances, according to
the purpose for which it is required.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Alexandre Deutsch in the Great Seal
Patent Office on the 16th June 1853.1
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
ALEXANDRE DEUTSCH, Manufacturer, of Paris, in the French Empire,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of December, 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 Alexandre
Deutsch, Her special licence that I, the said Alexandre Deutsch,
my executors, administrators, and assigns, or such others as
I, the said Alexandre Deutsch, 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 ex-
pressed, 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 "CERTAIN
IMPROVEMENTS IN TREATING OIL OF COLZA AND SIMILAR OIs," upon
the condition (amongst others) that I, the said Alexandre Deutsch,
by an instrument in writing under my hand and seal, should parti-
cularly 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 Alexandre Deutsch, do hereby
declare the nature of the said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof (that is to say):
My Invention relates to the preparation of an oil or oils suit-
able for oiling wool in the processes of combing, carding, and spin-
ning, by treating oil of colza or any of the varieties of rape oil,
or oil extracted from the seeds of plants of the genus Brassica, in
manner herein-after described.
I place the oil of colza or any of the varieties of oil above men-
tioned in a pan or boiler, which I prefer to be of copper. The pan
is heated by a fire placed under it, or in any other suitable manner,
until the oil begins to boil, and the fire is regulated so as to
keep the oil in a regular state of ebullition for three or four hours,
more or less. A quantity of spongy scum or impurity separates
from the oil, and after a time this scum acquires a black or dark
brown colour, and begins to subside, and the oil becomes clear and
transparent, and of a green colour. The fire is then removed, and
the oil is allowed to settle for one or two days, more or less, and
the clear green oil is then drawn off. If the oil has not acquired
a green colour, it is an indication that the process has not been
well performed, or that the oil employed was of inferior quality. Oil
of colza and rape oil thus treated may be advantageously employed
for the oiling of wool in the processes of its manufacture, and they
may also be employed for the lubrication of machinery. When oil
treated according to my Invention is to be employed for the lubri
cation of machinery, and it is desired to diminish its fluidity, a
solution of caoutchouc obtained by boiling caoutchouc in oil of colza
or rape oil, may be added to the oil, which should be heated and
well stirred to effect a uniform mixture. The oil may also be
rendered less fluid by mixing it with tallow or other solid grease.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I wish it to be understood that
what I claim is,—
The manufacture or preparation of an oil or oils suitable for
being advantageously employed for oiling wool in the processes of
its manufacture, and also adopted for the lubrication of machinery

page_text: by treating oil of colza, or any of the varieties of rape oil, or oil
extracted from the seeds of plants of the genus Brassica, in manner
herein-before described.
In witness whereof, I, the said Alexandre Deutsch, have here-
unto set my hand and seal, this First day of June, in the
year of our Lord One thousand eight hundred and fifty-
three.
Witness,
THO. TAYLOR,
