page_text: LETTERS PATENT to Albert Sauvée, of 22, Parliament Street, West-
minster, in the County of Middlesex, Civil Engineer, for the Inven-
tion of "IMPROVEMENTS IN THE APPARATUS USED FOR DYEING MATERIALS
EITHER WOVEN, SPUN, OR IN SKEINS OR HANKS."-A communication from
abroad by Monsieur César Corron, Dyer, of Saint Etienne (Loire),
France.
Sealed the 19th February 1875, and dated the 1st September 1874.
PROVISIONAL SPECIFICATION left by the said Albert Sauvée at the
Office of the Commissioners of Patents, with his Petition, on the
1st September 1874.
I, ALBERT SAUVÉE, of 22, Parliament Street, Westminster, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN the Apparatus USED FOR DYEING
MATERIALS, EITHER WOVEN, SPUN, OF IN SKEINS OR HANKS," to be as
follows:-
The apparatus which is the object of this Invention consists in an
ordinary dyeing vat, on which are fixed frames supporting a series of
rollers, to which are suspended the materials (skeins or hanks of
yarn, etc.) to be dyed. To these frames an up-and-down motion and
L

page_text: a horizontal to-and-fro motion are given. The up-and-down motion is
produced by means of parallel and vertical cords attached to the frames.
These cords pass over various sets of pulleys and are united at one
point. At this point the up-and-down motion is imparted to the frames.
by means of a rack and pinion, or any other suitable appliance. By this
and
arrangement, without fixed guides of any kind, the frame moves up
down in a vertical line.
The horizontal to-and-fro motion is produced either by means of cords
attached to the frame or by means of rollers fixed to the bottom part of
the frame and rolling on the edge of the vat.
Instead of the part of the manipulation called wringing, and also the
mechanical drying by means of passing the material between two fixed
cylinders, another mode of drying is employed, which consists in passing
the materials between two cylinders, which can be brought more or less
close to each other. The cylinders having been separated or opened all
the skeins or other materials, suspended to a roller, are placed between
them and the cylinders raised towards the roller, so that more than half
the length of the skeins hangs under the cylinders. These are then
closed and lowered, thus pressing out the liquid from this part of the
skeins, which are then turned end for end on the roller, and the above
process is repeated.
One man can give the horizontal motion to all the frames of one vat
at the same time, or even, by means of suitable connections, to the
frames of several vats.
To render the treatment of the smaller materials to be dyed more easy
large vats, divided transversely by water-tight partitions, are employed,
so that each compartment may have a different kind of dye. By this
means a saving in room and cost of establishment is made.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the First day of September, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs, and successors,
5 give and grant unto me, the said Albert Sauvée, Her special licence
that I, the said Albert Sauvee, my executors, administrators, and
assigns, or such others as I, the said Albert Sauvée, 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 "IMPROVEMENTS IN
THE APPARATUS USED FOR DYEING MATERIALS, EITHER WOVEN, SPUN, OR IN SKEINS
OR HANKS," a communication to me from abroad. by Monsieur César
Corron, Dyer, of Saint Etienne (Loire), France, upon the condition
(amongst others) that I, the said Albert Sauvée, my exccutors or admi-
nistrators, by an instrument in writing under my, or their, or one of
their hands and scals, 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 Albert Sauvée, do hereby declare
the nature of the said Invention, and in what manner the same is to
bo performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Sheet of Drawings
hereunto annexed, and to the letters and figures marked thereon (that
is to say):-
The apparatus which is the object of this Invention consists in an
ordinary dyeing vat D, above which are suspended the movable frames C
supporting a series of rollers B, from which hang the materials (skeins
or hanks of yarn, etc.) to be dyed. To these frames an up-and-down
motion and a horizontal to-and-fro motion are given. The up-and-down
motion is produced by means of parallel and vertical cords e, e, attached
to the frames at d, d. These cords pass over various sets of pulleys
P, P¹, P¹, and are united at one point. At this point the up-and-
down motion is imparted to the frames by means of a rack and pinion p,

page_text: or any other suitable appliance. By this arrangement, without fixed
guides of any kind, the frames move up and down in a vertical line.
The horizontal.to-and-fro motion is produced either by means of cords
attached to the frames, or by means of rollers n fixed to the sides or
bottom part of the frames and rolling on the edge of the vat.
Instead of the part of the manipulation called wringing, and also the
mechanical drying by means of passing the materials between two
fixed cylinders, another mode of drying is employed, which consists in
passing the materials between two cylinders, which are brought more
or less close to each other. The cylinders having been separated or
opened, all the skeins or other materials, hanging from a roller, are placed
between them and the cylinders raised towards the roller, so that more
than half the length of the skeins hangs under the cylinders. These
cylinders are then closed and lowered, thus pressing out the liquid from
this part of the skeins, which are then turned end for end on the roller,
and the above process is repeated.
One man can give the horizontal motion to all the frames of one vat,
or even by means of suitable connections to the frames of several vats.
To render the treatment of the smaller materials to be dyed more
easy large vats, divided transversely by water-tight partitions, are
employed, so that each compartment may have a different kind of dye.
By this means a saving in room and cost of establishment is made.
In witness whereof, I, the said Albert Sauvée, have hereunto set
my hand and seal, this Twenty-seventh day of February, in
the year of our Lord One thousand eight hundred and seventy-
five.
Witness,
H. J. ALLISON.
