IMPROVE- MENTS IN APPARATUS TO BE USED IN DYEING, BLEACHING, AND OTHER PROCESSES IN WHICH GOODS ARE OPERATED UPON IN THE PIECE
Year: 1852

page_text: LETTERS PATENT to Henry Thomson, of Clitheroe, in the County
of Lancaster, Calico Printer, for the Invention of "IMPROVE-
MENTS IN APPARATUS TO BE USED IN DYEING, BLEACHING, AND OTHER
PROCESSES IN WHICH GOODS ARE OPERATED UPON IN THE PIECE."
Sealed the 11th May 1853, and dated the 24th November 1852.
PROVISIONAL SPECIFICATION left by the said Henry Thomson
at the Office of the Commissioners of Patents, with his Petition,
on the 24th November 1852.
I, HENRY THOMSON, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS TO BE USED IN DYEING,
BLEACHING, AND OTHER PROCESSES IN WHICH GOODS ARE OPERATED UPON IN
THE PIECE to be as follows:-
"
My improvements relate to a novel method of conveying bands
of piece goods through dyes, bleaching matters, or other substances.
The peculiar feature consists in passing a band of the goods to be
operated upon over a roller or rollers (or other apparatus capable
of being turned) in such a manner that it shall be wound in a spiral
form, the two ends being joined together. The goods, however,.

page_text: are not wound tightly upon the apparatus, but are allowed to loop
down so as to present loose portions to the action of the dye or other
matter; by which means endless bands of the goods are obtained
of considerable length.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Henry Thomson in the Great Seal
Patent Office on the 21st May 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
HENRY THOMSON, of Clitheroe, in the County of Lancaster, Calico
Printer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twenty-fourth. day of November,
One thousand eight hundred and fifty-two, in the sixteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Henry Thomson, Her especial license that I, the
said Henry Thomson, my executors, administrators, and assigns, or
such others as I, the said Henry Thomson, my executors, adini-
nistrators, 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 "IMPROVE.
MENTS IN APPARATUS TO BE USED IN DYEING, BLEACHING, AND OTHER
PROCESSES. IN WHICH GOODS ARE OPERATED UPON IN THE PIECE," upon the
condition (amongst others) that I, the said Henry Thomson, by an
instrument in writing 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 and immediately after the date of the said Letters Patent.
NOW KNOW YE, that -I, the said Henry Thomson, do hereby.
déclare the nature of my said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascer
tained in and by the following statement and accompaning Drawings
(that is to say):
-
My improvements relate to a novel method of conveying bands
of picce goods through dyes, bleaching matters, or other substances:
The peculiar feature consists in passing a band of the goods over a
roller or rollers, or other apparatus capable of being turned, and in
such manner that it shall be wound in a spiral form, the two ends
being joined together so as to constitute an endless rope. The
goods, however, are not wound tightly upon the apparatus, but are
allowed to loop down, so as to present loose portions to the action of
the dye or other matters. By this means endless bands of goods
may be obtained of considerable length by joining together any
practicable number of pieces. The form of apparatus to be em-
ployed will be varied to a certain extent according to the process to
which my Invention is to be applied. I have, however, to this my
Specification appended a Drawing, showing the improvement as ap-
plied to a dyeing copper, which illustration will serve as an example
for all competent persons. Figure 1, is a longitudinal section of
the apparatus, and Figure 2, a transverse view, also in section. The
dye copper a, is provided with a partition b, which does not however
extend to the bottom, but terminates with a pipe at c, into which
pipe steam may be admitted in order to heat the dyeing matters.
In place of the usual winch, there is a cylinder d, having rotary mo-
tion communicated to it by any convenient means, and above. is a:
roller e, the axis of which is mounted in slots so as to allow it to
press by its weight upon the surface of the cylinder d. A rail g,
provided with projecting parts h, extends along the copper, and at
cach end thereof is mounted a guide roller i. The pieces of goods
to be operated upon are stitched together in the usual manner; one
end is drawn between the cylinder d, and roller e, passed under the..
steam pipe c, and carried upwards on the other side thereof so as to
pass again between the. cylinder and roller. This operation being
repeated until the whole length constituted by the pieces of goods
has been passed onward, a series of spiral coils will have been

page_text: formed, each one being separated from the others by occupying a
position between two of the projecting pins h. These coils, however,
are not distended between the upper and lower portions, but a
number of loose folds are allowed to accumulate in the copper,
as shewn in the drawing. This arrangement having been com-
pleted, the two ends of the combined pieces of goods are passed re-
spectively under and over the guide rollers i, i, and joined together
by stitching or other suitable means. Upon rotatory motion being
now therefore communicated to the cylinder d, the goods will be
passed through the copper with an endless spiral motion, which
may be continued until the requisite operation has been completed.
In order to prevent the goods, when passing over the cylinder d,
from lapping around it, I apply a revolving angular roller %, which
receives rotatory motion by a strap placed upon the axis of the
cylinder d. I have in the foregoing description alluded particularly
to a dye copper. It will be evident, however, that the same system
may be adopted for dunging, soaping, chymicing, washing, or other
similar operations in which endless bands of goods may be operated
upon, and that the modifications required for such adaptations will
be readily arranged by all competent persons.
Having thus described and ascertained the nature of my said
Invention, and the manner of carrying the same into effect, I desire
it to be understood that I claim as secured to me the arrangement
of piece goods in an endless spiral form for the purposes above set
forth.
In witness whereof, I, the said Henry Thomson, have hereunto
set my hand and seal, this Fifth day of May, in the year of
our Lord One thousand eight hundred and fifty-three.
