AN IMPROVED MACHINE FOR THE CLEANSING OF TEXTILE AND FIBROUS SUBSTANCES
Year: 1856

page_text: LETTERS PATENT to Louis Dartois, of 39, Rue de l'Echiquier, Paris, in
the Empire of France, and of 4, South Street, Finsbury, London,
Middlesex, for tho Invention of "AN IMPROVED MACHINE FOR THE CLEANSING
OF TEXTILE AND FIBROUS SUBSTANCES."
Scaled the 28th April 1857, and dated the 21st November 1856.
PROVISIONAL SPECIFICATION left by the said Louis Dartois at the Office
of the Commissioners of Patents, with his Petition, on the 21st
November 1856.
I, LOUIS DARTOIS, of 39, Rue de l'Echiquier, Paris, in the Empire of
France, and of 4, South Street, Finsbury, London, Middlesex, do hereby
declare the nature of my said Invention for "AN IMPROVED MACHINE FOR THE
CLEANSING OF TEXTILE AND FIBROUS SUBSTANCES," to be as follows, that is to
say:
This improved apparatus for cleansing textile and fibrous substances consists
of a suitable frame or standard, having at each end two cylinders placed one
over the other, the axes of which work in bearings on a slotted guide frame or
support, which allows the pressure of the cylinders to be adjusted according
to the nature of the article to be treated; the two lower cylinders are
grooved, if necessary. The material to be treated is formed into skeins or
otherwise, and fed into the groove of one pair of cylinders, by which it is

page_text: submitted to the compressing action of the upper cylinder, the pressure being
regulated by a weighted lever. The material then passes into a twister, com-
posed of a number of bobbins placed in a suitablo frame, which is made to
revolve by a wheel gearing, After this operation the twisted material passes
between the second pair of cylinders, put in action by a winch handle or other
means, and then into a funnel, and as it egrosses passes over a roller into a
suitable receptacle. On the axis of the first lower cylinder is a large spur
wheel, receiving motion by means of intermediate gearing from a pulley driven
by any motive power. A suitable vessel is placed under the apparatus to
receive the liquid extracted from the material.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Louis Dartois in the Great Seal Patent Office on the
20th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, Louis
DARTOIS, of 39, Rue de l'Echiquier, Paris, in the Empire of France, and of
4, South Street, Finsbury, London, Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of November, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Iler
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Louis Dartois, Ifer special license that I, the said Louis Durtois, my
executors, administrators, and assigns, or such others as I, the said Louis
Dartois, 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
tern of years 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 "AN IMPROVED
MACHINE FOR THE CLEANSING OF TEXTILE AND FIBROUS SUBSTANCES," upon tho
condition (amongst others) that I, the said Louis Dartois, by an instrument in
writing under my hand and seal, should particularly describe and ascertain the
nature of my said Invention, and in what manner the same was to be per:
formed, 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 Louis Dartois, do hereby declare thọ
nature of the said. Invention, and in what manner the same is to be performed,

page_text: to be particularly described and ascertained in and by the following statement
thereof, reference being had to the annexed Sheet of Drawings, and to the
figures and letters marked thereon, that is to say:-
The Invention consists of an improved construction of machine for cleans-
ing fibrous substances from grease and other impurities before or after being
dyed. This object is effected in a continuous manner and more expeditiously
than by the ordinary means. In the Drawing herein-after described the
same letters refer to parts which are similar.
Figure 1 is a side elevation, and Figure 2 a plan of the improved machine.
A is the framing; B, B', aro metal or wooden cylinders; they may be
formed with a semicircular groove in the middle of their length. C, C¹,
metal or wooden cylinders covered with fibrous or compressible materials;
D, twister, in which is engaged the chain E, formed of a certain number of
skeins crossed one over the other, which chain after having passed over the
small cylinder F, through the funnel G, between the cylinders B, C, and
been pressed by the two cylinders B', C', finally egresses from the machine,
passing over the small cylinder H; I, I, represent the driving pullies;
J, K, L, M, N, O, cog wheels; P, Q, bevil wheels; R, R, are the spindles
of the twister, through which passes the chain formed of skeins of fibrous
substances to be cleansed; the spindles may be fixed or moveable, and
their number may be varied. S represents a lever; T, two sliding plummer
blocks; U, lever connecting rod; V, weight, which may be varied so as to
increase or diminish the pressure on the cylinder B'. This arrangement for
pressing the materials may also be applied to the cylinder C. X, recipient,
placed under the whole of the machine to receive the liquids compressed out
of the fibrous materials during the process; Y, crank handle, fixed on the axis
of the cylinder C, serving to draw the substances to be cleansed under tho
cylinders. The machine may be put in action any suitable motive power
applied to the driving pullies. The materials are put into basins placed in
front and independent of the machine. The two cylinders B, B', may be
free from pressure, and the cylinders C, C', may have on their circumference
a semicircular groove for the substances under treatment to pass through.
The method of working the machine is as follows:-The chain of fibrous
materials to be cleansed is conducted over the roller H between the cylinders
B, C, whence it passes through the twister D, between the cylinders B, C,
and thence through the funnel G upon the roller F. The chain then egresses
from the machine into the recipient X.
Having now described the nature of my said Invention, and in what manner
the same may be carried into effect, I wish it to be understood that I do not

page_text: confine myself to the precise details herein laid down, but what I claim is, the
construction of a machine for cleansing fibrous or textile materials as herein-
before described, and referred to in the accompanying Sheet of Drawings.
In witness whereof, I, the said Louis Dartois, have hereunto set my
hand and seal, this Sixteenth day of May, in the year of our Lord
One thousand eight hundred and fifty-soven.
Witness,
GOSSET LEBRUN.
LIS DARTOIS. (L.S.)
