Improved Apparatus for Dyeing and otherwise treating Textile
Fabrics.
I, CÉSAR CORRON, of St. Etienne, Loire France, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
--
My invention relates to the construction of a machine for dyeing fabrics, wherein
these are kept extended to their full width during the dyeing, mordanting, washing
and other processes, instead of being folded or pleated.
Another peculiarity consists in using one and the same apparatus for dyeing, and
either mordanting, washing or brightening, or for simultaneously dyeing in two
different colours or two shades of the same colour.
Lastly, the fabric, while maintained stretched to its full width, is subjected to a
fulling operation by means of a compressing roller acting on the fabric.
For these purposes the apparatus consists of a tank in which are arranged three
horizontal rollers that serve to support, convey and keep stretched the fabric to be
dyed. The main tank by preference contains an inner tank in which the fabric is
folded together and which can contain a bath of a different nature from that of the
main tank.
Thus if the latter. contains the dye, the inner tank can contain the mordant,
washing or brightening liquor, or a dye bath different from that of the main
tank.
On each side of the main tank are pivotted upright rocking levers with balance
weights at bottom and carrying at their upper ends another roller to which they
impart an oscillating motion."
The rocking motion is imparted to the levers by connecting rods from cranks on a
shaft at the one end of the main tank, such shaft being driven by the main driving
shaft through suitable gearing; the connection of the rods with the rocking levers is
made adjustable so as to vary at will the extent of the motion of the levers. The
main shaft drives by means of pitch wheels and endless chains, pitch wheels loose
on the pivots of the rocking levers, which pitch wheels impart their motion through
other endless chains and pitch wheels to the roller carried by the rocking levers.
The main shaft also drives by means of other pitch wheels and chains, two of the
first named rollers that are submerged in the dye bath, and the third of these
rollers is driven from one of the other two also by pitch wheels and endless chain.
By this arrangement all three submerged rollers as also the upper oscillating one
receive rotary motion at the same speed in the same direction, so that the fabric
to be dyed, which is led over them has a uniform travel imparted to it thereby. -
The two ends of the piece of fabric being united together so as to form an endless
web, it is made to pass first from one of the submerged rollers at one end of the main
tank up over the oscillating roller which by its combined rotary and to and fro motion
delivers it in regular folds or laps into the inner tank, from which the fabric is drawn
by the second intermediate submerged roller and is delivered thereby to the third one
at the other end of the tank, which roller delivers it, underneath the bottom of the
inner tank back to the first one again.
'
The oscillating levers carry above the revolving roller, a second smaller one which
is pressed in contact with the revolving one, and thereby exercises a fulling action
upon the fabric passing between them. As the fabric is drawn from the inner tank
by the intermediate roller, it passes under the edge of a board, which has the effect of
smoothing it out as it is drawn from under the folds.
..
When it is desired to remove the folds of fabric from the inner bath, for the
purpose of renewing the latter when exhausted of colouring matter, a tray running on

page_text: wheels on the edges of the main tank is run under the oscillating roller, so that this
is then made to deliver the fabric in folds into this tray instead of into the bath. The
tray has a perforated or grated bottom through which the liquor can drain from the
fabric.
This tray also serves to receive the fabric after the dyeing process is completed.
In order to cause the rollers to exercise a laterally stretching effect upon the fabric
they are by preference provided with helical ribs extending in contrary directions
from their middles towards the ends, which by their rotation tend to stretch the cloth
towards each end. In some cases however the ribs may be arranged parallel to the
roller's axis instead of helically.
If in the above described apparatus, it is not desired to treat the fabric with two
different liquids, the inner tank may be replaced by an open tray or cage which
receives the folds of the fabric and allows the liquid of the bath to pass through it.
There may also be provided in the main tank one or more perforated tubes
extending across the bath underneath some part of the stretched fabric, through which
pipe or pipes steam is made to issue so as to act upon the fabric and the bath, and by
forming the perforations so that the steam issues from them in oppositely inclined
directions, or so that the steam jets are larger in the centre than at the ends, they
may be made to assist in stretching the fabric.
When treating pile fabrics with this apparatus it is preferred to take two pieces of
fabrics and place them with their pile faces against each other, so as to protect these
from the pressure of the rollers.

COMPLETE SPECIFICATION.
Improved Apparatus for Dyeing and otherwise treating Textile
Fabrics.
I, CÉSAR CORRON. of St. Etienne, Loire, France, Manufacturer, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
My invention relates to machinery for dyeing fabrics so arranged that they are
kept extended to their full width during the mordanting, dyeing, washing and other
processes connected therewith, instead of being folded or pleated. Another peculiarity
consists in the use of the same apparatus for dyeing, and either mordanting washing
or brightening, or for dyeing in two colours or shades at the same time. Lastly, the
fabric while stretched to its full width undergoes fulling by means of a compressing
reller acting on it.
The accompanying drawings represent apparatus according to my invention.
Fig. 1 is a side view, Fig. 2 is a plan, and Fig. 3 an end view; Fig. 4 is a
transverse section on M N of Fig. 1; Fig. 5 is a longitudinal section.
In a tank A are mounted three rollers B, C, D, to carry and traverse the fabric in
its full width. Within the tank A there is by preference a bath E in which the
fabric becomes laid in folds. The tank A may contain the dye and the bath B may
contain liquor for mordanting, washing or brightening, or it may contain a dye like
or not to that in A.
At each side of the tank A are counterweighted levers F carrying a wringing
roller G which turns while the levers F oscillate on their pivots c.
These parts are worked by gearing as follows.
The main shaft H carrying the fast and loose pullies P P¹ works by pinion a and
wheel b the countershaft which has crank discs m connected by rods to pins n
on the levers F, causing them to oscillate, the extent of oscillation of the wringing
roller being regulated as required by the position of the crank pins on the
discs m.

page_text: A chain wheel d on shaft H is connected by chain e to one side of a chain wheel f
of double width which is free on its axle, the other side off being connected by
chain g, to chain wheel h on the axis of the roller G. At the other end of the shaft H
are two chain wheels, the one o connected by chain p to wheel g which by chain ris
connected to wheels on the shaft of the drawing roller D; the other wheel ton H is
connected by chain u to a wheel on the shaft of the roller B which drives the roller C.
Thus the four rollers B, C, D and G are made to revolve all in the same direction at
the same speed, causing the fabric to travel uniformly as indicated by the arrows a in
Figs. 1 and 5.
Above the wringing roller G a roller K is mounted on the levers F with springs y,
pressing it on G for fulling the fabric when required. The wringing roller G by its
oscillation folds the fabric in the bath E whence it is drawn uniformly and passed
underneath through the dyeing tank, then raised by the wringing roller which folds
it afresh until the dyeing is completed.
A board or blade L resting on the fabric prevents its folds from being irregularly
dragged out. When it is required to remove the fabric for the purpose of renewing
or strengthening the bath, a carriage R with grated bottom is run under the wringing
roller to receive the fabric which is laid on it in folds.
The rollers B, C, D and G are arranged to keep the fabric extended to full width
while it is moved along the bath. This result is attained by imposing a lateral drag
on the edges of the fabric proportional to the strain tending to gather it towards the
middle. Figs. 6 and 7 shew on an enlarged scale a form of roller which answers this
purpose. On two end wheels are fixed staves carrying helical ribs a inclined to
opposite bands on each side of the middle so as to stretch the fabric from the middle.
In some cases fluted rollers as shewn in Figs. 8 and 9, may be used. When it is
not desired to have two separate baths the inner tank E may have a grated bottom.
Several perforated pipes M may be arranged under the fabric for injecting steam, and
these may be made to aid in stretching the fabric in width by graduating the per-
forations as shewn in Figs. 10 and 11 from a large size in the middle to smaller size
towards each end.
The holes described may, for the same purpose, be made inclined from the middle
outwards, towards the ends.
The apparatus described may be used to dye fabrics in width; when it is used for
dyeing velvet, two webs are placed together face to face so that the pile may not be
flattened down by the rollers.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. In dyeing apparatus, in combination with a dyeing bath and traversing rollers a
wringing roller mounted on oscillating levers so as to lay the fabric in folds, sub-
stantially as described.
2. The arrangement within the main bath of a secondary bath holding liquor for
mordanting, washing, brightening or second dyeing, substantially as described.
3. For stretching the fabric in width, the use of rollers with helical ribs inclined
oppositely from the middle.
4. The arrangement in the bath of perforated steam pipes, substantially as and for
the purpose set forth.
5. In combination with the wringing roller G the pressing roller K and its spring
bearings.
6. The combination of the wheels and chains for driving the rollers B C D G and
the cranks for working the oscillating levers F, substantially as described.
