page_text: LETTERS PATENT to Nathaniel Lloyd, of the City of Manchester, in
the County of Lancaster, for the Invention of "IMPROVEMENTS IN
DIVINA COLORING MATTERS ON PREPARED FABRICS OR YARNS."
Sealed the 23rd July 1872, and dated the 24th January 1872.
PROVISIONAL SPECIFICATION left by the said Nathaniel Lloyd at
the Office of the Commissioners of Patents, with his Petition, on
the 24th January 1872.
I, NATHANIEL LLOYD, of the City of Manchester, in the County of
Lancaster, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN FIXING COLORING MATTERS ON PREPARED FABRICS OR YARNS," to
be as follows:-
My Invention or discovery relates to the fixing and brightening of
colors dyed, padded, or printed on prepared cloth or yarn, with the
extracts of madder or garancine, or the artificial alizarine of commerce.
To prepare my goods I pass them when they are intended to be dyed
through oil, or a combination of oil and soda, or oil and ammonia, or oil.

page_text: and potash, as usual in preparing for Turkey red, and after the oil is
fixed and the goods mordanted in the usual way, I dye them in a bath
containing an excess of the coloring matter, which enables me to dye
them in a very much shorter time than at present; but the dye not
being then fixed, I afterwards expose them to the action of steam, which
causes the color to adhere to the goods, and they are then ready for the
usual brightening operations.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nathaniel Lloyd in the Great Seal Patent Office
on the 24th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHANIEL
LLOYD, of the City of Manchester, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of January, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Nathaniel Lloyd, Her special license
that I, the said Nathaniel Lloyd, my, executors,, administrators,
and assigns, or such others as I, the said Nathaniel Lloyd, 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 FIXING COLORING, MATTERS ON PREPARED FABRICS OR YARNS," upon the
condition (amongst others) that I, the said Nathaniel Lloyd, 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 Nathaniel Lloyd, do hereby
declare the nature, of my said Invention, and in what, manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
My Invention or discovery relates to the fixing and brightening of
colors dyed, padded, or printed on prepared cloth or yarn, with the
extracts of madder or garancine, or the artificial alizarine of commerce.
To prepare the goods I pass them when they are intended to be dyed
through oil, or a combination of oil and soda, or oil and ammonia, or oil
and potash, as usual in preparing for Turkey red, and after the oil is
fixed and the goods mordaunted in the usual way, I dye them in a bath
containing an excess of the coloring matter, whereby a great saving of
time is effected. To fix the color I then expose the goods to the action
of steam in any convenient way, after which operation they are ready
for the usual brightening operations.
Having now described the nature of my Invention, I desire it to be
understood that I claim,-
First. Dyeing prepared cloth or yarn with the extracts of madder or
garancine, or the artificial alizarine of commerce, in a bath containing
an excess of the coloring matter.
And, secondly. Submitting prepared cloth or yarn after being dyed,
padded, or printed with the extracts of madder or garancine, or the
artificial alizarine of commerce to the action of steam to fix the colors.
In witness whereof, I, the said Nathaniel Lloyd, have hereunto set
my hand and seal, this Twenty-second day of July, in the year
of our Lord One thousand eight hundred and seventy-two.
Signed, sealed, and delivered by the
before-named Nathaniel Lloyd, in
the presence of
