Year: 1866

page_text: LETTERS PATENT to John Charlton and Henry Charlton, of the City of
Manchester, in the County of Lancaster, Calenderers and Finishers, for
the Invention of "IMPROVEMENTS. IN STRETCHING WOVEN FABRICS DURING
more DungreeRS OF STIPPENING AND SIZING THEM."
Sealed the 7th August 1866, and dated the 10th February 1866.
PROVISIONAL SPECIFICATION left by the said John Charlton and Henry
Charlton at the Office of the Commissioners of Patents, with their
Petition, on the 10th February 1866.
We, JOHN CHARLTON and HENRY CHARLTON, of the City of Manchester, in
the County of Lancaster, Calenderers and Finishers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN STRETCHING WOVEN FABRICS
DURING THE PROCESSES OF STIFFENING AND SIZING THEM," to be as follows:-
Our Invention consists in the application of grooved rollers between the
sizing and drying processes for the purpose of stretching the woven fabrics
transversely or in the width during the said operations, and also in passing
the fabric between a plain bowl or roller and one of the said grooved rollers

page_text: previous to its passing between the grooved rollers, by which process we gain
an improved method of feeding the grooved rollers for the purpose of stretching
or extending the cloth or fabric in the width.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Charlton and Henry Charlton in the Great Seal Patent
Office on the 9th August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
CHARLTON and HENRY CHARLTON, of the City of Manchester, in the County of
Lancaster, Calenderers and Finishers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of February, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said John Charlton and Henry Charlton, Her special license that we, the
said John Charlton and Henry Charlton, our executors, administrators, and
assigns, or such others as we, the said John Charlton and Henry Charlton,
our 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 STRETCHING
WOVEN FABRICS DURING THE PROCESSES OF STIFFENING AND SIZING THEM,"
upon the condition (amongst others) that we, the said John Charlton and
Henry Charlton, our executors or administrators, by an instrument in
writing under our, or their, or one of our or 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 we, the said John Charlton and Henry Charlton, do
hereby declare the nature of our said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Figures on the accom-
panying Sheet of Drawings, and to the letters of reference marked thereon
(that is to say):

page_text: Our Invention consists in the application of grooved rollers between the
stiffening or sizing and drying processes for the purpose of stretching the
woven fabrics transversely or in the width during the said operations, and also
in passing the fabric between a plain bowl or roller and one of the said grooved
rollers previous to its passing between the grooved rollers, by which process we
gain an improved method of feeding the grooved rollers for the purpose of
stretching or extending the cloth or fabric in the width, whether the sizing
process is used or not.
On the accompanying Sheet of Drawings Fig. 1 is a vertical section of a
sizing machine provided with a plain bowl and grooved rollers, and Fig. 2 an
outside view of one end of the rollers drawn about full size. In Fig. 1, a
represents the framework of the machine; b, the size trough; c, d, the sizing
rollers; e, a plain bowl; f, g, the grooved rollers; h, the gearing by which
they are driven; i, one of the screws for raising and lowering the upper
grooved roller; j, k, guide rollers; 1, the fabric; and m, one of the drying
cylinders. When the machine is at work the fabric to be. sized and dried
passes over the guide roller j, between the sizing rollers c, d, between the top
sizing roller and the plain bowl e, between the grooved rollers f, g, and then
over the top grooved roller f and over the guide roller k to the drying cylinders.
By raising or lowering the top grooved roller the projecting rings of both of
the grooved rollers are entered more or less in the grooves, so that the fabric
can be more or less stretched, and when these grooved rollers are u: "in
connection with a plain bowl the stretching operation is performed in
efficient manner. In some cases the fabric from the sizing rollers c, d, i
partly over the plain bow! e when stretching is not required, and then bet..een
the said bowl and the bottom grooved roller g to the guide roller k, the fabric
in this instance being marked n.
'ry
es
We do not confine ourselves to the exact arrangement of the plain bowl and
grooved rollers as shown in Fig. 1, as they may be placed at any desired distance
from the sizing rollers, either by making the framework wider or placing them
in a separate frame.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we claim the application of grooved rollers between the
stiffening or sizing and drying processes for the purpose of stretching the
woven fabrics transversely or in the width during the said operations, and also
the passage of the fabric between a plain bowl or roller and one of the said
grooved rollers previous to its passing between the grooved rollers, by which
process we gain an improved method of feeding the grooved rollers for the

page_text: purpose of stretching or extending the cloth or fabric in the width, whether
the sizing process is used or not.
In witness whereof, I, the said Henry Charlton, for and on behalf of
myself and the said John Charlton, have hereunto set my hand and
seal, this Seventh day of August, in the year of our Lord One thousand 5
eight hundred and sixty-six.
Signed, sealed, and delivered by the
within-named Henry Charlton, in
the presence of
E. J. HUGHES,
Patent Agent,
Manchester.
