Drying Fibrous or Textile Materials.
1, CARL BOHRINGER of Waldkirch, Baden, 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 stateinent :-
This invention relates to a novel method of, and apparatus for, dyeing, washing
and drying vegetable or animal fibre, yarns or other textile materials, in continuous
succession.
My said improved method which will be more readily understood from the
description hereinafter given of the apparatus employed for carrying the same into
effect consists in placing into the perforated basket of a centrifugal machine the yarn
or other material to be dyed, washed and dried in continuous succession, and then
connecting successively, by means of one and the same conduit, the interior of the
casing of the machine and its perforated basket containing the said material, with a
suitable source of colour, of water, and of air in such a manner as to cause, by
means of three three-way cocks properly adjusted, first the dye from the said source
of colour to enter, through the said conduit the interior of the casing and its enclosed
basket and fill the same, then to turn one of the three-way cocks and thereby cause
a circulation of the dyer's bath through the perforated basket, its onclosed material
the three-way cocks and their common conduit, then to employ the centrifugal
machine of the dyer's bath, then to turn again two of the said three-way cocks in
the proper positions and force washing water through the interior of the casing and
its perforated basket which with its contained dyed textile material is now revolved,
and finally increasing the rotary speed of the basket and by another adjustment of
two of the three-way cocks, cutting off the flow of water and forcing a current of air
through the interior of the machine so as to dry the dyed and washed material
therein.
For carrying into effect my said improved method of dyeing, washing and drying
textile materials in continuous succession I have designed the apparatus illustrated in
the accompanying drawing in which
Figure 1 is a vertical central section, and
Figure 2 a plan view of the same.
Referring to Figure 1 of the drawing, W designates a vertical shaft suspended by
means of the bearing in the yoke-shaped bracket A upon the casing K of a centrifugal
machine and carrying near its lower end the fixed bottom D of the basket T. The

page_text: lower part B of the vertical shaft W is made hollow and provided with lateral openings B
surrounded by the basket T which consists of the perforated annular inner wall D and
perforated annular outer wall D' both fastened upon the bottom disc D and receiving
between them at their upper ends the two halves or segments of the lid or cover D³. The
basket is enclosed in the casing K of the centrifugal machine which is provided with the
outlet H and with another opening connecting with one of the flanges of the three-
flange pipe E having the three-way cock H and being connected by its two other
flanges, respectively with the pipe F of a receptacle X containing the colour
(arranged below the machine and not fully shown), and with the suction pipe G of a
forcing pump P. The hollow part B of the shaft W connects with a pipe-conduit H
whose extension J (broken away in the drawing) establishes the connection with a
suitable source of water (not shewn). Within the conduit J are inserted two three-
flange pipes J and J of which the one, J', is provided with the three-way cock H'
and the other J with the three-way cock H and whose flanges not in line with the
conduit J, are connected, respectively, with the air-pipe L, and the forcing conduit G
of the pump P. It will thus be seen that according to the position in which the
three-way cocks H H H are adjusted, the basket T by means of the one conduit H
will be put in communication with the receptacle X for colour, or with the
suction pipe G of the pump for causing the dyer's bath to circulate, or with
the source of water or with the pipe L for drying air. The inner wall
of the basket T is provided with an upper non-perforated cylindrical extension the
end of which is fastened to a gland B2 upon the shaft W, thus forming the space R
around the latter, said space R being connected by holes B₁ with the hollow part
of the shaft W, and by the perforated part of the inner wall D' with the interior
of the basket T, and the two parts D2, D3 of the lid are also provided with two
segmental extensions D encircling the said extension of the basket T and allowing
of adjusting the lid in a vertical direction and then holding upon the material
to be treated in the basket in a fixed position by means of the collar D.

In carrying into effect my improved method of dyeing, washing and drying
textile or similar material in continuous succession I proceed as follows-After
having filled the basket T with the material to be treated the lid D is brought
down upon the latter and held in place by the collar De closing upon the
extension D and fastened by means of a set-screw. The three-way cocks H'H'
and Hare then adjusted, so that by means of H³, the suction pipe G of the
P is in open communication with the receptacle X containing the colour and
by means of H and H³, the forcing conduit G¹ of the pump P is in open connection
with the conduit H, and, thus, with the hollow part of the shaft W, whereupon the
pump P is set at work to draw the colour from the receptacle X through cock H' and
pipe G and force it through pipe G1, cocks H2, H3, and conduit H into the hollow
part B of the shaft W. The colour enters the space R through the holes B' and
thence penetrates into the basket T through the perforated wall D) of the latter,
impregnates the textile goods therein contained, and enters through the perforated
wall D, the space formed by the casing K, the outlet H' being at this time kept
closed by means of a plug, valve or other suitable means. When the colour has
risen to be in a level with the lid D³, the three-way cock H¹ is turned so as to
close the communication between the receptacle X and the pump P and to open
connection between the latter and the interior of the casing K which adjustment
of the cock H¹ will cause a circulation of the dyer's bath to take place through
the suction pipe G and through the same conduits and cocks just referred to. The
impregnation of the material with the dyer's bath being completed, the pump P
is stopped and the three-way cock H' turned again now to bring the interior of
the casing K in communication with the pipe F and thus to allow the dyer's bath
to flow back by means of its own gravity into the receptacle X. This being done,
the outlet H is opened and the three-way cock H¹ turned to cut off the com-
munication with the casing K, while the three-way cock H³ is now turned so that
the source of water only is connected with the hollow part of the shaft W through
pipes J and H and thus water only is allowed to enter the basket T. The water

page_text: being thus introduced and the basket T being slowly rotated by means of a belt
(not shown) and pulley P³ upon the shaft W, the dyed material in the basket will
be penetrated and washed by the water which will flow off through the perforations
of the wall D2 and then leave the machine through the outlet H. When the water
is coming out of the outlet H in a perfectly pure state, the flow of water is cut
off by turning the three-way cock H³ to close the extension of the pipe J connected
with the source of water, and the three-way cock_H' is turned to open the com-
munication between the conduit H and the pipe L connected with the source of
drying air. By these means, the basket T and its contents are now receiving a
continuous current of drying air only which will penetrate the material in the
basket T the latter being at this time rotated with greater velocity so that the
material within the same is dried rapidly under the combined action of the centri-
fugal force and drying air passed through the basket. Said air may also be taken
in a heated state from any convenient source.
Instead of causing the dyer's bath to flow back into the receptacle X as herein
described, the said bath after use may also be allowed to run out through the
outlet H¹.
By suspending the shaft W by means of an upper bearing C I attain the result
characterizing my present invention inasmuch as this arrangement enables me to
establish from below a momentary successive communication between the hollow
part B open at the lower end of the shaft and the sources of colour, water and air.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
First. The method substantially as herein described of dyeing washing and drying
vegetable and animal fibre, yarns and other textile materials in continuous succession,
said method consisting in first connecting with a receptacle containing the liquid
colour, the basket of a machine containing the said materials and provided with a
cominon inlet conduit controlled by a system of three-way cocks, by a proper adjust-
ment of the latter and a forcing pump, until the said basket and the space within the
casing surrounding the same is filled with the liquid colour to a level with the basket's
lid then adjusting the three-way cocks so that the pump will cause a circulation of the
dyer's bath to take place through the basket, the three-way cocks and common conduit,
then emptying the basket and centrifugal machine of the dyer's bath, then adjusting
the three-way cocks so that washing water only is forced through the basket now
slowly revolved, and finally adjusting the three-way cocks in such position as to cause
drying air only to pass through the common conduit and the basket which with its
dyed and washed contents is at such time revolved with greator velocity, substantially
as and for the purpose specified.
Second. In an apparatus for carrying into effect the improved method of dyeing
washing and drying vegetable and animal fibre, yarns and other textile materials in
continuous succession as herein described, the combination, with a centrifugal machine
having a vertical shaft W suspended by means of a bearing Cand having the hollow
part B open at the lower end and provided with the lateral holes B', of the perforated
basket T the conduits H and J having the three-way cocks Hand H³, the air pipe L
connected with the cock H2, the forcing conduit G¹ connected with the cock H2; the
forcing pump P, the conduit G the three-way cock H' in the three-flange pipe E, and
the pipe F of the receptacle X arranged at a lower level than the centrifugal machine
substantially as and for the purpose specified.
