Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
DONALDSON, of Haslingden, in the County of Lancaster, "Woollen Printer,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twentieth day of November, in the ninth year of Her reign, and
in the year of our Lord One thousand eight hundred and forty-five, did, for
Herself, Her heirs and successors, give and grant unto me, the said James.
Donaldson, Her especial license, full power, sole privilege and authority,
that I, the said James Donaldson, my executors, administrators, and assigns,
and such others as 1, the said James Donaldson, 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 expressed, should and
lawfully might make, use, exercise, and vend, within England and Wales and
the Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS
IN THE PROCESSES OF SCOURING, BLEACHING, AND WASHING WOOL, COTTON, SILK AND
OTHER FIBROUS SUBSTANCES, BOTH IN A RAW OR MANUFACTURED STATE;" in which
said Letters Patent is contained a proviso that I, the said James Donaldson,
shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be enrolled in Her

page_text: 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
James Donaldson, do hereby declare that the nature of my Invention,
and the manner in which the same is to be performed, is particularly
described and ascertained in and by the following explanation thereof (that
is to say) :-
My improvements in the processes of scouring, bleaching, and washing
wool, cotton, silk, and other fibrous substances, consist in the employment or
use of a novel compound or mixture of materials to be substituted in the
place of urine and other matters now commonly employed in such processes, as
I have found, from practical experience, that the improved compound being
the subject of this Invention is much more efficient in its scouring or cleansing
qualities. My improvements are to be effected by the use of the compound
produced according to the following formula:-Boil twenty pounds of
potatoes in three gallons of water, and crush them into a paste, then put in
thirty pounds of soda ash gradually, then introduce two gallons of spirits of
ammonia, and stir the ingredients well together; and when well mixed add by
degrees sixty pounds of common salt. This will make about one hundred-
weight of the scouring or bleaching compound, which, when well mixed, must
be spread in a shallow vessel similar to a brewer's cooler, for the ready action
of the atmosphere, thus allowing the oxygen to dissipate the spirit. This com-
pound may be made in large quantities, if preferred, and stored for use, as it
does not deteriorate in quality either by age or exposure; and in some cases, if
thought necessary, a small quantity of lard or other grease may be added to
prevent the crystallization of the ingredients.
Having now described the nature of my Invention, together with the
manner of carrying the same into practical effect, I would remark, in con-
clusion, that I claim as my Invention the employment or use of the above-
described composition in the processes of scouring, bleaching, and washing
wool, cotton, silk, and other fibrous substances, both in a raw or manufactured
state.
In witness whereof, I, the said James Donaldson, have hereunto set
my hand and seal, this Nineteenth day of May, in the year of our
Lord One thousand eight hundred and forty-six
JAMES (L.s.) DONALDSON.
