IMPROVEMENTS IN THE PROCESS OF DYEING TEXTILE FABRICS
Year: 1872

page_text: LETTERS PATENT to Joseph Richardson of Brookfoot Dye Works,
near Brighouse, in the County of York, Dyer and Finisher, for the
Invention of "IMPROVEMENTS IN THE PROCESS OF DYEING TEXTILE
FABRICS."
Sealed the 11th February 1873, and dated the 12th August 1872.
PROVISIONAL SPECIFICATION left by the said Joseph Richardson at
the Office of the Commissioners of Patents, with his Petition, on
the 12th August 1872.
I, JOSEPH RICHARDSON, of Brookfoot Dyc Works, near Brighouse,
in the County of York, Dyer and Finisher, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE PROCESS OF DYEING TEXTILE
FABRICS," to be as follows:-
Heretofore in the dyeing of textile fabrics it has been customary to
make or prepare a bath in a "dyc vessel" of dye liquor as near the
strength or colour or shade of colour as experience will enable the dyer
or operative to effect. The fabrics are then introduced for the purpose of
being dyed, when after due time they are examined, and if found not

page_text: to be of the proper colour or shade required they have to be taken out
of the bath for the introduction of other or more colouring matters, and
then the fabrics again introduced, and so on, to any number of times,
always removing the goods for alteration or addition of dyeware to the
bath or dyc vessel until the proper colour or shade is obtained.
Now my improvements consist in preparing, dissolving, or mixing
colouring matters, dyowares, acids, and alkalies in a separate vessel or
feeder (by preference placed at a higher level) and provided with a pipo
and stop tap so that additional liquors may be supplied to the dye vessel
(when required) while the fabrics are in the vessel and in motion or
being dyed, thereby avoiding the loss of time and labour in removing
the fabrics for the introduction of additional dyewares, as is now .the
practice.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Richardson in the Great Seal Patent Office
on the 12th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
RICHARDSON of Brookfoot Dye Works, near Brighouse, in the County
of York, Dyer and Finisher, send greeting.
•
WHEREAS Her most Excellent Majesty Queen Victoria, by Her'
Letters Patent, bearing date the Twelfth day of August, in the year
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Richardson, Her special
licence that I, the said Joseph Richardson, my exccutors, adminis-
trators, and assigns, or such others as I, the said Joseph Richardson,
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, usc,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN THE PROCESS OF DYEING TEXTILE FABRICS," upon the condition
(amongst others) that I, the said Joseph Richardson, 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

page_text: 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 Joseph Richardson, 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 and accompanying Sheets of Drawings, that
is to say:
:
Heretofore in the dyeing of textile fabrics it has been customary to
make or prepare a bath in a “ dye vessel" of dye liquor as near the
strength, or colour, or shade of colour as experience will enable the
dyer or operative to effect. The fabrics are then introduced for the pur-
pose of being dyed, when after due time they are examined and if found
not to be of the proper colour or shade required they have to be taken
out of the bath for the introduction of other or more colouring matters,
and then the fabrics again introduced, and so on, to any number of times,
always removing the goods for alteration or addition of dyeware to the
bath or vessel until the proper colour or shade is obtained.
.
Now my improvements consist in preparing, dissolving, or mixing
colouring matters, dyewares, acids, and alkalies in a separate vessel or
feeder (by preference placed at a higher level) and provided with a pipe
and stop tap so that additional liquors may be supplied to the dye vessel
(when required) while the fabrics are in the vessel and in motion or,
being dyed, thereby avoiding the loss of time and labour in removing
the fabrics for the introduction of additional dyewares, as is now the
practice.
In order that this Invention may be more clearly understood I herein
give reference to the accompanying' Sheets of Drawings marked with
figures and letters of reference, the same letter referring to the samo
part in the various views or figures.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation, and Fig. 2 is a front elevation of an ordinary
dye vessel with my improvements applied thereto.
A is the said vessel in which the fabrics are to be dyed, and B is a.
separate vessel placed (by preference) at a higher level in which the
colouring matters, dyewares, acids, and alkalies are prepared, dissolved,

page_text: or mixed in the same manner as heretofore was done in the ordinary
dyc vessel. This vessel is provided with a pipe C extending into the
bottom part of the dye vessel; and D is a stop tap for regulating
the flow or supply of the dye liquor to the dye vessel that portion
of the pipe marked E being perforated to effect an equal distribu-
tion of dye liquor. F is a pipe and tap for supplying water to the
vessel B. It will be readily understood that if whilst the fabrics are
being dyed and in motion it is found necessary to introduce extra
colouring matter by simply turning the stop tap D any quantity may be
allowed to flow into the dye vessel through the perforations in the
pipe E, this pipe being so placed that the colouring matter in issuing
therefrom shall infringe upon the side of the dye vessel, and thus
become intimately mixed with the colouring matter previously contained
in the vessel before it is taken up by the fabrics. By mcans of this
apparatus I am enabled not only to avoid the loss of time consequent :
upon the frequent removal of the fabrics, as in the present practice of
dyeing, but also to regulate the quantity of colouring matter introduced
with the greatest nicety.
Having thus fully described the nature of my said Invention, I
would have it understood that I do not claim the whole of the parts 2
herein shewn and described, but what I claim as my Invention is, the
preparing in a separate vessel any drugs, dyewares, or colouring matters
required for dyeing, and conducting the same or introducing them to the
dye vessel whilst the goods or fabrics are in motion or during the
operation or process of dyeing them.
In witness whereof, I, the said Joseph Richardson, have here-
unto set my hand and seal, this Tenth day of February, in the
year of our Lord One thousand eight hundred and seventy-three.
