page_text: LETTERS PATENT to Joseph Ormrod Ramsbottom, of Bury, in the County
of Lancaster, Spinner and Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS POR STIFFENING, DRYING,
STRETCHING, AND FINISHING COTTON AND SILK WOVEN FABRICS.
Sealed the 19th October 1866, and dated the 21st April 1866.
PROVISIONAL SPECIFICATION left by the said Joseph Ormrod Rams-
bottom at the Office of the Commissioners of Patents, with his Petition,
on the 21st April 1866.
I, JOSEPH ОBMROD RAMSBOTTOM, of Bury, in the County of Lancaster,
Spinner and Manufacturer, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR STIFFENING,
DRYING; STRETCHING, AND FINISHING COTTON AND SILK WOVEN FABRICS," to be as
follows:-
My Invention is designed for the purpose of effecting the process of stiffening,
drying, and finishing woven silk or other fabrics in one machine, and consists
in a novel arrangement, combination, and adaptation of mechanism for the
purpose, which is so construced that during the passage of the piece through
the machine the fabric will become stiffened, stretched, dried, and finished at
one operation, instead of being submitted to these processes at séparate
times.

page_text: The improvements consist in the arrangement and combination of a trough
containing stiffening material, and a series of delivery and feed rollers, and a
roller to apply the stiffening material with a large steam cylinder or drum,
such as is now well known and commonly used for the purposes of drying and
finishing, and also in the application of a double series of pins to the periphery
of the steam cylinder by which the fabric is stretched. The fabric passes
between feed rollers over the stiffening roller, which rotates in a trough con-
taining shellac and spirit, and thereby receives the required amount of
stiffening material; the selvedges of the fabric are then pressed by means of
small rollers or bowls on to the double row or series of pins, which are mounted
on ribs or bars encircling the steam cylinder; these ribs or bars have space to
slide laterally, and are caused to move by guide rollers or bowls from a
minimum width at the point of supply to a maximum width at the point of
delivery, and to return again during the revolution of the cylinder to the mini-
mum width before commencing entering the selvedges again. Thus the fabric
in passing over the roller and applying stiffening material is stiffened, and on
being taken over the revolving steam cylinder it becomes dried by the heat,
and stretched by the expanding and contracting double series of pins, and in
which finished state it is delivered on to a roller from the pins at their widest
stretch.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Ormrod Ramsbottom in the Great Seal Patent
Office on the 20th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
ORMROD RAMSBOTTOM, of Bury, in the County of Lancaster, Spinner. and
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of April, 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 me, the
said Joseph Ormrod Ramsbottom, Her special license that. I, the said
Joseph Ormrod Ramsbottom, my executors, administrators, and assigns, or
such others as I, the said Joseph 'Ormrod Ramsbottom, 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

page_text: Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR STIFFENING, DRYING, STRETCHING, AND FINISHING COTTON AND SILK WOVEN
FABRICS," upon the condition (amongst others) that I, the said Joseph Ormrod
Ramsbottom, 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 Joseph Ormrod Ramsbottom, do
Bereby declare the nature of the 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 Drawings (that is to say) :-
My Invention is designed for the purpose of effecting the process of stiffening,
drying, and finishing woven silk or other fabrics in one machine,, and consists
in a novel arrangement, combination, and adaptation of mechanism for the
purpose, which is so constructed that during the passage of the piece through
the machine the fabric will become stiffened, stretched, dried, and finished
at one operation, instead of being submitted to these processes at separate:
times..
trough
The improvements consist in the arrangement and combination of a
containing a stiffening material, and a series of delivery and feed rollers, and
a roller to apply the stiffening material with a large steam cylinder or drum,
such as is now well known and commonly used for the purposes. of drying
and finishing, and also in the application of a double series of pins to the
periphery of this steam cylinder by which the fabric is. stretched. The fabric
passes through feed rollers over the sizing roller, which rotates in a trough
containing shellac and spirit, and thereby receives the required amount of
stiffening material; the selvages of the fabric are then pressed by means
of small rollers or bowls on to the double row or series of pins, which are
mounted on ribs or bars encircling the steam cylinders; these ribs or bars
have space to slide laterally, and are caused to move by guide rollers or bowls.
from a minimum width at the point of supply to a maximum width at the
point of delivery, and to return again during the revolution of the cylinder to
the minimum width before commencing entering the selvages again. Thus
the fabric in passing over the roller applying the stiffening material is stiffened,
being taken over the revolving steam cylinder it becomes dried
by the heat, and stretched by the expanding and contracting double series of
and

page_text: pins, and in such finished state it is delivered on to a roller from the pins at
their widest stretch.
:
In order that the Invention may be better understood and explained in
detail I have hereunto attached a Sheet of Drawings made upon a scale of
about one inch and a half to the foot, similar letters of reference being marked
upon corresponding parts of the apparatus.
Fig. 1 represents a side elevation of the improved machinery for stiffening;
stretching, and drying fabrics in one operation; and Fig. 2 represents a front
elevation of the same."
../
In Figs. 1 and 2, a, a, is the framing of the machine on which the brackets or
stands supporting the "gudgeon" b which forms the axle of the large revolving
drum care secured; the steam pipe d admits steam through the "gudgeon" 6
and the pipe e, e, into the hollow jacket or casing f of the drum c; on the
surface of this drum c the projecting rims or bands g supplied with the points
pr pins i, i, are caused to slide in a lateral direction by means of the adjust-
able guide rollers h, h; the trough or receptacle k, in which the stiffening
material is contained, being suitably situated at one end of the machine and
secured to the framing 1; upon this framing also the stiffening and guide
rollers m, m are supported, by which the pieces of piled fabric are conducted
on to the machine. The operation to which the fabric is submitted whilst
passing through the machine will be understood by the following description:
The piece is conducted by the rollers m, m, over the stiffening roller m³, by
which means the back of the piece receives a constant and regular supply of
stiffening, after leaving the stiffening roller m¹ it passes under the rollers n, n,
which force or depress the selvages of the same on to the pins or retaining points
i, i; these points being connected to the rims or bands 9, 9, encircling the
steam cylinder are caused as the drum c revolves to slide by means of the
guide rollers h, h, in a lateral direction upon the surfaces of the cylinder.
Thus at the point of supply when the selvages of the fabric are first placed
upon the pins, the rims or bands are at their minimum width, and are caused
by the guide rollers h, h, gradually to recede from each other as the cylinder
revolves to a maximum width at the point of delivery, when the piece is passed
from the machine on to the receiving roller in a stiffened, stretched,
and dried state, the rims or bands 9, g, being caused to contract during the
remaining revolution of the cylinder, so as to assume their original position for
receiving the fabric from the sizing roller.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim the general arrangement and construction of apparatus

page_text: for simultaneously stiffening, drying, and stretching woven silk or other
fabrics, as herein;before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, I, the said Joseph Ormrod Ramsbottom, have
hereunto set my hand and seal, this Thirteenth day of October, in
the year of our Lord One thousand eight hundred and sixty-six.
JOSEPH ORMROD RAMSBOTTOM. (L.8.)
