Manufacturing Chemist, do hereby declare the nature of the said Invention
for CERTAIN IMPROVEMENTS IN DYING," to be as follows:-
J
My Invention consists in the use of nitrate of soda, sulphate of soda,
chloride of sodium, sulphate .of magnesia, sulphate of lime, and chloride
of calcium in dying cotton with logwood, quercitron bark, Sapan wood, peach
wood, Lima wood, and other dye woods of the same description. Either of the
above-named salts by itself, or a mixture of two or more of them, may be used
with any of the dye materials named above. The salts may either be put
into the dye bath at the same time as the other materials, or they may be
mixed with the dye woods beforehand.

filed by the said Frederick Albert Gatty in the Great Seal Patent Office
on the 4th April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
ALBERT GATTY, of Accrington, in the County of Lancaster, Manufacturing
Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the. Tenth day of October, in the year of our Lord.
One thousand eight hundred and fifty-six, in the twentieth year of Her
reign; did, for Herself, Her heirs and successors, give and grant unto me,
the said Frederick Albert Gatty, Her special license that I, the said Frederick
Albert Gatty, my executors, administrators, and assigns, or such others as I,
the said Frederick Albert Gatty, 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
"CERTAIN IMPROVEMENTS IN DYING," upon the condition (amongst others) that
I, the said Frederick Albert Gatty, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
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 Frederick Albert Gatty, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement:-
My Invention consists in the use of nitrate of soda, sulphate of soda,
chloride of sodium, sulphate of magnesia, sulphate of lime, and chloride of
calcium in dying cotton with logwood, quercitron bark, Sapan wood, peach
wood, Lima wood, and other dye woods of the same description.
In carrying my Invention into effect, I find that one pound of either of the
above-named salts, or a mixture of two or more of them, placed in the vat with
fifteen pounds of any of the above-named dye materials, produces a good
result; the quantity of the salts may, however, be varied, as an excess produces
no bad effect. Instead of mixing the said salts with the dye materials in the

page_text: vat, as described above, they may be previously mixed with the dye materials.
The process of dying is carried on in the ordinary manner.
Having now described the nature of my Invention, and the manner of
performing the same, I declare that I claim the use of the above-named salts,
either separately, or a mixture of two or more of them, in dying with the
dye materials named above.
In witness whereof, I, the said Frederick Albert Gatty, have here-
unto set my hand and seal, this Third day of April, in the year of
our Lord One thousand eight hundred and fifty-seven.
F. A. GATTY. (L.S.)
