IMPROVEMENTS IN, THE PREPARATION AND DYEING OF YARNS OR THREADS
Year: 1860

page_text: LETTERS PATENT to Joseph Goddard, of Stockport, in the County of
Chester, Dyer, for the Invention of "IMPROVEMENTS IN, THE PREPARATION
AND DYEING OF YARNS OR THREADS."
Sealed the 10th July 1860, and dated the 13th January 1860.
PROVISIONAL SPECIFICATION left by tho said Joseph Goddard at the
Office of the Commissioners of Patents, with his Petition, on the .13th
January 1860.
I, JOSEPH GODDARD, of Stockport, in the County of Chester, Dyer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
PREPARATION AND DYEING OF YARNS OR THREADS," to be as follows:-
My Invention relates principally to the preparation of such yarns as aro
known as "doubled" yarns to be dyed black, whereby I am enabled to pro-
duce or impart a greater lustre to the yarns during the subsequent process of
polishing and finishing.
The improvements consist, first; in boiling the yarns (generally in the hauk)
in plain water, after which they are steeped in a solution of catechu (also com-
mercially known as "cutch" or "gambia") and sulphate of copper mixed in
suitable proportions for about eight hours or more. They are then to be passed
through lime water, and afterwards through a solution of sulphate of iron, then
through lime water again, and next through a decoction. of logwood and fustic,.
to which is added a solution of sulphate of iron. After the yarns have passed

page_text: through, they are then passed through the mixture of logwood, fustic, and sul-
phate of iron; they are passed through lime water again, and through logwood
and fustic again, and through the mixture as before, and lastly, through a
solution of soap and water, and dried, and if required, polished and finished as
usual.
By-thus- treating the yarn with the solution of catechu and sulphate of
copper before dyeing, they are rendered capable of receiving a better lustre in
polishing, and of retaining the dye better, being more permanent and of an
improved color and general appearance.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Goddard in the Great Seal Patent Office on the 12th
July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
GODDARD, of Stockport, in the County of Chester, Dyer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth January in the year of our Lord One
thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Goddard, Her special license that I, the said Joseph Goddard, my
executors, administrators, and assigns, or such others as I, the said Joseph
Goddard, 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 THE PRE-
PARATION AND DYEING OF YARNS OR THREADS," upon the condition, amongst
others, that-I, the said Joseph Goddard, by an instrument under my hand
and seal, 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 after immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Goddard, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say :-
My Invention relates principally to the preparation of such yarns as are

page_text: "
known as "doubled yarns to be dyed black, whereby I am enabled to pro-
duce or impart a greater lustre to the yarns during the subsequent process of
polishing or finishing.
The improvements consist, first, in boiling the yarns (generally in the hank)
in plain water, after which are steeped in a solution of catechu (also commonly
known as "cutch," "scutch," or "gambia,") and sulphate of copper mixed in
suitable proportions, for about eight hours or more; they are then to be passed
through lime water, and afterwards through a solution of sulphate of iron, then
through lime water again, and next through a decoction of logwood and fustic,
to which is added a solution of sulphate of iron. After the yarns have passed
through it, they are then passed through the mixture of logwood, fustic, and
sulphate of iron; they are now passed through lime water again, and through
a solution of logwood and fustic, and through the mixture as before, and finally
through a solution of soap and water, and dried, and if required, polished and
finished as usual.
By thus treating the yarns with the solution of catechu and sulphate of
copper before dyeing they are rendered capable of receiving a better lustre in
polishing, and of retaining the dye better, and more permanent, and of an
improved color and general appearance. The proportions of the ingredients
forming the first solution is, for every twenty pounds of yarn is of gambia or
catechu about twelve pounds, sulphate of copper two pounds, and twenty
pounds of water, the proportions of the dyeing liquor being about the same
as usual.
Having now described the nature of the said Invention, I wish it to be
distinctly understood that I claim the preparing and dyeing of such yarns as
are known as "doubled" yarns, or other descriptions of yarns requiring to be
dyed black by the aforesaid means, the whole of which is herein-before described,
set forth, and fully explained.
In witness whereof, I, the said Joseph Goddard, have hereunto set
my hand and seal, this 11th day of July, in the year of our Lord
One thousand eight hundred and sixty.
JOSEPH GODDARD.
