page_text: BERRY'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MILES
BERRY, of the Office for Patents, 66, Chancery Lane, in the County of
Middlesex, Patent Agent, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Ninth day of May, in the third year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Miles
Berry, Her especial licence, full power, sole privilege and authority, that I,
the said Miles Berry, my executors, administrators, and assigns, and such
others as I, the said Miles Berry, my executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein mentioned, should and lawfully might
make, use, exercise, and vend, within England, Wales, the Town of Berwick-
upon-Tweed, and in all Her Majesty's Colonies and Plantations abroad, an
Invention of "CERTAIN IMPROVEMENTS IN TREATING, REFINING, AND PURIFYING
OIs," being a communication from a Foreigner residing abroad; in which said
Letters Patent is contained a proviso obliging me, the said Miles Berry, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of the said Invention, and in what manner the same is to
be performed, and to cause the same to be inrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after the
date of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Miles Berry, do hereby declare that the nature of the said Invention, and the

page_text: manner in which the same is to be performed, are particularly described and
ascertained in and by the following description thereof (that is to say):-
The following is the description of the said Invention of Certain Improve-
ments in Treating, Refining, and Purifying Oils, as communicated to me by
my correspondent, a Foreigner residing abroad:-A description of the process
for treating, refining, and purifying (whale) oils, rendering them incongealable,
and to abstract from them two products, oleine and stearine. Process for
removing the smell:-I heat the oil in its primitive or rough or original state,
by the steam of water up to forty-five degrees of Reaumer. I add to it the
quarter of its weight of a clear solution of chlorine of soda, at fifteen degrees.
After a stirring or mixing of above twenty minutes, I leave it to repose for about
three days, in vats arranged or calculated for that purpose; after which time
it is decanted or poured of from the precipitate, and treated with an infusion
of acid of nutt galls or gallic acid, which unites with or seizes upon the
gelatine (which exists in all animal oils). I then stir briskly during fifteen
minutes. I stop a moment to add nitric acid, in the proportion of two ounces
per hundred pounds. I then stir again for some minutes, and the oil is then
transferred in this state to the vats to repose. Three days suffice for the
gelatine and other extraneous or foreign bodies to precipitate. The oil is
then free from smell, and purified from all impure matter. I pour it off
from the sediment to put into other vats, in order there to perform the third
operation.
Third operation. The separation of the oleine and the stearine.-One
part of acetate of alumine, one part of nitrate of potash, one part of chromate
of lime, of each two pounds per one hundred pounds. I dissolve these three
substances in water, in the proportion of five per cent. I mix these solutions
with the oil. I stir for twenty minutes. The action is such that at the
instant even several crystals of stearine are seen to separate themselves from
the oleine. After a day of repose it is poured into bags of felt, of a conical
shape. The oleine passes through, and the stearine is retained in the felt bags,
in the consistency of butter. This matter is afterwards submitted to a rather
strong pressure, in order to obtain it as hard as possible, This oleine is as
soft as olive oil, burns without smoke or smell, and may be very advantageously
used for greasing wools in cloth manufacture. Stearine is much used in the
arts.
In witness whereof, I, the said Miles Berry, have hereunto set their
hands and seals, this Ninth day of November, in the year of our Lord
One thousand eight hundred and forty.
MILES (L.8.) BERRY.
