Year: 1856

page_text: LETTERS PATENT to James Hargraves, of the Woollen Works, Carlisle,
in the County of Cumberland, for the Invention of "IMPROVEMENTS IN THE
་་
APPARATUS USED FOR DYEING FABRICS"
Sealed the 30th May 1856, and dated the 25th March 1856.
PROVISIONAL SPECIFICATION left by the said James Hargraves at the
Office of the Commissioners of Patents, with his Petition, on the 25th
March 1856.
1, JAMES HARGRAVES, of the Woollen Works, Carlisle, in the County of
Cumberland, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN THE APPARATUS USED FOR DYEING FABRICS," to be as follows:-
This Invention has for its object improvements in apparatus used for dyeing
fabrics. Heretofore apparatus has been used for dyeing fabrics and yarns by
stopping out certain or determined parts of the fabrics by pressing surfaces,
allowing the dye liquor to get to the other parts of the fabrics or yarns not
pressed on, and in doing so it has been usual to employ frames, and between
corresponding parts of two such frames (in each case) a fabric or a layer of
yarns has been pressed, so that when several frames (held tightly together with
fabrics or yarns between them) have been introduced into dye liquor, the dye
has only acted on the impressed parts of the fabrics or yarns so held."
Now, my improvements consist of a peculiar combination of mechanical
parts of such like apparatus, in order that several such frames may be mounted
on and revolved with axes when placed in the dye liquor. For these purposes,
three strong plates, or it may be open frames, are used; two of them have axes
or necks formed on or fixed thereto; these two frames are connected together,

page_text: but at a distance apart, by screw bolts and nuts or other convenient means;
the third plate or frame is capable of sliding on the screw bolts, and by means
of screws of being set up from one outer plate towards the other, so as to press
a series of frames together, such frames, as heretofore, being provided with press-
ing surfaces, between which the fabrics are placed and pressed. A rotatory
motion is communicated to the combined apparatus above explained when in
the dye liquor, by means of a pinion taking into a cog wheel fixed on one of
the axes above mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Hargraves in the Great Seal Patent Office on the
11th September 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
IIARGRAVES, of the Woollen Works, Carlisle, in the County of Cumberland,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by IIer Letters
Patent, bearing date the Twenty-fifth day of March, in the year of our
Lord, One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign did, for Herself, er heirs and successors, give and grant unto me, the
said James Hargraves, Her special licence that I, the said James Hargraves,
my executors, administrators, and assigns, or such others as I, the said
James Hargraves, 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
APPARATUS USED FOR DYEING FABRICS," upon the condition (amongst others) that
I, the said James Hargraves, my executors or administrators, by an instru-
ment 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 James Hargraves, do hereby declare
the nature of the 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 thereof. that is to say :-

fabrics. Heretofore apparatus has been used for dyeing fabrics and yarns by
stopping out certain or determined parts of the fabrics by pressing surfaces,
allowing the dye liquor to get to the other parts of the fabrics or yarns not
pressed on, and in doing so it has been usual to employ frames, and between
corresponding parts of two such. frames (in each case) a fabric or a layer of
yarns has been pressed, so that when several frames (held tightly together with
fabrics or yarns between them) have been introduced into dye liquor, the dye
bas only acted on the impressed parts of the fabrics or yarns so held.
Now, my improvements consist of a peculiar combination of mechanical
parts of such like apparatus, in order that several such frames may be mounted
on and revolve with axes when placed in the dye liquor. For these purposes,
three strong plates, or it may be open frames are used; two of them have axes
or necks formed on or fixed thereto; these two frames are connected together, but
at a distance apart, by screw bolts and nuts or other convenient means; the third
plate or frame is capable of sliding on the screw bolts, and by means of screws
of being set up from one outer plate towards the other, so as to press a series
of frames together, such fraines, as heretofore, being provided with pressing
surfaces, between which the fabrics are placed and pressed. A rotatory motion
is communicated to the combined apparatus above explained when in the dye
liquor, by means of a pinion taking into a cog wheel fixed on one of the axes
above mentioned.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.

forming the same, I would have it understood that I make no claim to any of
the parts separately, nor do I confine myself to the precise details; but what
I claim is the combination of parts herein described.
In witness whereof, I, the said James Hargraves, have hereunto set my
hand and seal, this Eighth day of September, in the year of our Lord
One thousand eight hundred and fifty-six.
