page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of April, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and.grant unto us, the
said George Fergusson Wilson and William Walls, Her special licence that
we, the said George Fergusson Wilson and William Walls, our executors,
administrators, and assigns, or such others as we, the said George Fergusson
Wilson and William Walls, our 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 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 "AN IMPROVE-
MENT IN DYEING TURKEY RED," upon the condition (amongst others) that we,
the said George Fergusson Wilson and William Walls, by an instrument in
writing under our hands and seals, or under the hand and seal of one of us,
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, on behalf of
myself and the said William Walls, do hereby declare the nature of the said
Invention, and in what manner 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 employing oleic acid in the process of dyeing
Turkey red, in place of the oils heretofore used; and we prefer to employ for
this purpose oleic acid which has been distilled, and as pure as may be.
Having thus stated the nature of our said Invention, we will proceed to
describe the manner of performing the same.
In the treating of oils and fatty matters, both animal and vegetable, for the
purposes of manufacturing the same into candles and for other uses, much
oleic acid is produced, and it is, as compared with the oil now used in the
dyeing Turkey red, a low-priced product, and we have discovered that it can
be used in substitution of the oil now employed in such dyeing process, and
that oleic acid appears to have peculiar properties which are advantageous in
the dyeing of Turkey red. The treating of yarns and fabrics when dyeing
Turkey red by the use of olive oil being well known, it will not be necessary
to describe the same here; and it will only be requisite to state, that in the use
of oleic acid according to our Invention, in place of or in combination with

page_text: the oils now used, the oleic acid, whether obtained from animal or vegetable
oils or fats, should be as pure as may be. For this reason we prefer to use such
oleic acid as has been distilled by the use of heated steam, as is now well
understood; but this is not essential; and in employing oleic acid for these
purposes it is to be employed in like manner to olive oil, and a workman
accustomed to dyeing yarns and fabrics Turkey red by the aid of olive oil will
readily employ oleic acid in this process of dyeing, and he will not require
further description of the process.
In witness whereof, I, the said George Furgusson Wilson, have here-
unto set my hand and seal, this Thirtieth day of September, in the
year of our Lord One thousand eight hundred and fifty-four.
Witness,
JNO. ALCOCK.
