page_text: LETTERS PATENT to Benjamin Murgatroyd, of Bradford, in the
County of York, Dyer, for the Invention of "IMPROVEMENTS IN
WASHING OR SCOURING WOOL, ALPACA, AND MOHAIR, AND FABRICS
PROVISIONAL SPECIFICATION left by the said Benjamin Mur-
gatroyd at the Office of the Commissioners of Patents, with his
Petition, on the 22nd December 1853.
I, BENJAMIN MURGATROYD, of Bradford, in the County of York, Dyer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN WASHING OR SCOURING WOOL, ALPACA, AND MOHAIR, AND FABRICS COM-
POSED ENTIRELY OR PARTLY OF THOSE MATERIALS," to be as follows:-
My Invention consists in the use of potash in combination with
saponaceous substances. The compound may be formed by mixing

page_text: potash with any of the soaps ordinarily used for washing and scouring.
One method I adopt is to add potash to oleine, or substances of that
immediate class, so as to combine with the fatty matter and leave an
excess of alkali.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benjamin Murgatroyd in the Great Seal Patent
Office on the 21st June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
BENJAMIN MURGATROYD, of Bradford, in the County of York, Dyer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twenty-second day of December, in
the year of our Lord One thousand eight hundred and fifty-three, in
the seventeenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Benjamin Murgatroyd,
Her especial licence that 1, the said Benjamin Murgatroyd, my execu-
tors, administrators, and assigns, or such others as I, the said Benjamin
Murgatroyd, 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 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 "IMPROVEMENTS IN WASHING OR SCOURING WOOL, ALPACA,
AND MOHAIR, AND FABRICS COMPOSED ENTIRELY OR PARTLY OF THOSE MATE-
RIALS," upon the condition (amongst others) that I, the said Benjamin
Murgatroyd, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 Benjamin Murgatroyd, do
hereby declare the nature of my said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say):-
My Invention consists in the use of potash in combination with
saponaceous substances. The compound may be formed by mixing
potash with any of the ordinary soaps used for washing and scouring.
A method I prefer is to add potash to olcine, so as to combine with the
fatty matter and leave an excess of alkali.
The proportions may be varied to some extent, but I find a compound
to answer well, composed of twenty parts by measure of potash liquor,
of the strength of twenty Twaddle, and one of oleine. The potash liquor
I heat to about one hundred and twenty degrees Fahrenheit, and add
the oleine by degrees, with frequent agitation.
Having thus described the nature of my said Invention, I desire it
to be understood that I claim as secured to me, under the above in
part recited Letters Patent, the use for the purposes above set forth of
potash in combination with saponaceous substances, in such proportions
as to leave an excess of alkali.
In witness whereof, I, the said Benjamin Murgatroyd, have
hereunto set my hand and seal, the Twentieth day of June,
in the year of our Lord One thousand eight hundred and fifty-
four.
BENJAMIN MURGATROYD. (L.S.)
