Improvements in or relating to the Mordanting, Dyeing, Washing,
and otherwise Treating of Spun Yarn or the like, and Apparatus
therefor.
I, JULIUS OTTO OBERMAIER of Lambrecht, Palatinate, in the Empire of
Germany, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable yarn wound in spools as it comes from
the spinning frame to be dyed, bleached and otherwise treated, without putting it in
rows on separate tubes, thereby avoiding the necessity of subsequently winding or
reeling it again on spools or into cops.
It has indeed been found that the apparatus hitherto used in which the yarn was
placed in the dye or mordant, wound on tubes, singly and fitted in rows, have not
in practice fulfilled all the requirement of the industry.
This invention, enables the yarn after it has been wound on spools or into cops
and prepared for packing in a box, to be submitted to the whole series of the usual
operations viz. to be moistened, treated with mordant, dyed, bleached, washed etc.,
by different liquids introduced for the purpose each in a special receiver or
chamber; the batch of spools not requiring even to be opened, while each spool is
even more thoroughly treated in a special dye than it could be by the old methods,
as it may be submitted to its action several times over if required.
It has been proposed before to take the cops one by one and place them upon
tubes or tube-carrying spindles which preparatory arrangement caused considerable
loss of time. This invention enables a large number of cops to be treated in the
different baths at once and thereby to repeat the bath and to multiply indefinitely
its effects, the cops being combined into a bundle, batch or block in the condition
in which they are to be packed into the box and being retained in this compressed
condition during the whole time of the treatment.
These bundles or blocks may be of any suitable shape. A block of this
description may be formed by means of two plates, either perforated or not, and
two bands or ties rigidly attached to those plates; also two perforated or non-
perforated end plates and lastly four longitudinal rods.
The formation of bundles of cops or spools by means of these devices is as
follows:-
Within a frame formed by the plates and bands is fitted an end plate which
constitutes the bottom of supporting plate. Upon this the cops are placed in rows
or layers so that their aggregate bulk nearly reaches to the upper cross bands.
Then a second end plate forming the cover is inserted underneath the bands and
the cops are compressed by means of a press whereupon the longitudinal rods are
introduced between the bands and the end plates. The whole bundle is now turned
over and again compressed and then another pair of rods inserted between the
second end plate and the bands. The cops are thus firmly compressed and form a
homogeneous mass of yarn without any hollow or 'empty space between them.
The packets formed in this manner are now treated in apparatus constructed as
follows:-
A cylinder is arranged concentrically with another cylinder so that an annular
space is left between the two. This space is closed at the top and connected at the
bottom with a suction or delivery pipe of a pump. Radial receivers or receptacles
are attached to the outer cylinder in such a manner that the cylinder wall forms
their bottoms, the cylinder being perforated at the corresponding points. The open
end of each receiver is closed by means of a bent piece or yoke provided with a
perforated plate.

page_text: The packets of cops are placed in these receivers and the liquid with which the
cops, spools or the like are to be treated is then introduced into the space between
the two cylinders by means of the pump. The liquid passes through the perforated
bottoms of the receivers (formed by the cylinder wall) and penetrates the bundles
of cops after which it flows out again through the perforated cover plates of the
said receivers and into a tank which surrounds both the cylinders and the receivers.
It then may if necessary be caused by the pump to pass through the cylinders and
receivers once or several times more.
It will be understood that the liquid instead of being forced through the
receivers may be caused to pass through them by suction.
But
It has been before stated that ready-made bundles of cops are placed in the
receivers for the purpose of being treated in the manner just described.
instead of preparing the bundles before-hand, the spools or cops may be placed into
the receivers singly and there combined and compressed into bundles, so that after
undergoing the required treatment they may be removed one by one. The first.
described method, of connecting them into bundles preparatory to the dyeing or
bleaching process is however preferred.
In a modified arrangement the receivers are connected with a hollow body of
triangular section.
In another arrangement the receivers may be attached to the suction or delivery
pipe of the pump singly, while in another arrangement all the receivers may be
directly connected to the force pipe of the pump.
After the cops have been thus treated in the apparatus above described,--each
receiver being supplied with one particular dye mordant or other liquid, which
may be caused to circulate through it any required number of times, the whole of
the apparatus i.e., the whole series of receivers is placed into a centrifugal drying
machine to be freed from moisture.
From the foregoing it will be apparent that this invention enables very large
quantities of yarn already wound upon spools or in cops, to be subjected to all the
usual dyeing, bleaching, washing and other operations and the whole process may
be completed without so much as touching the cops or spools after once forming
them into bundle. These therefore retain unaltered the desired shape or form and
the points of the cops especially are protected from any deformation.
It will be understood from the above description that the apparatus employed in
carrying out this invention are capable of many modifications the forms of apparatus
here described being merely examples; the main point of the process being that
the ready-wound cops or spools to be treated are arranged in rows and compressed
into bundles and thus bodily submitted to the action of the liquid or liquids, in
such a manner that the liquid in passing through each bundle can take no other
course than the one in which it comes into contact with each fibre of the bundle.

COMPLETE SPECIFICATION.
Improvements in or relating to the Mordanting, Dyeing, Washing,
and otherwise Treating of Spun Yarn or the like, and Apparatus
therefor.
I, JULIUS OTTO OBERMAIER of Lambrecht, Palatinate in the German Empire,
do hereby declare the nature of this invention and in what manner the same is to
be perforined, to be particularly described and ascertained in and by the following
statement:
The object of this invention is to enable yarn wound in spools as it comes from
the spinning frame to be dyed, bleached and otherwise treated without putting it in
rows, on separate tubes, thereby avoiding the necessity of subsequently winding or
reeling it again on spools or into cops.

page_text: It has indeed been found that the apparatus hitherto used in which the yarn was
placed in the dye or mordant, wound on tubes singly and fitted in rows, have not in
practice fulfilled all the requirements of the industry.
This invention. enables the yarn after it has been wound on spools or into cops
and prepared for packing in a box, to be submitted to the whole series of the usual
operations viz. to be moistened, treated with mordant, dyed, bleached, washed etc.,
by different liquids introduced for the purpose each in a special receiver or chamber;
the batch of spools not requiring even to be opened, while each spool is even more
thoroughly treated in a special dye than it could be by the old methods, as it may
be submitted to its action several times over if required.
It has been proposed before to take the cops one by one and to place them upon
tubes or tube-carrying spindles, which preparatory arrangement caused considerable
loss of time. This invention enables a large number of cops to be treated in tho
different baths at once and thereby to repeat the bath and to multiply indefinitely
its effects, the cops being combined into a bundle, batch or block in the condition
in which they are to be packed in the box and being retained in this compressed
condition during the whole time of the treatment.
These bundles or blocks may be of any suitable shape.
As shown in Fig. 1 of the accompanying drawings a block of this description
may be formed by means of two plates a a, either perforated or not, and two bands.
or ties rigidly attached to those plates; also two perforated or non-perforated
plates c c (Fig. 2) and lastly four rods d.
The formation of bundles of cops or spools by means of these devices is as
follows:-
Within a frame formed by the plates a a and bands bb is fitted a plate e which
constitutes the bottom or supporting plate. Upon this the cops are placed in rows
or layers so that their aggregate bulk nearly reaches to the upper cross bands b..
Then a second plate e forming the cover is inserted underneath the bands b and the
cops are compressed by means of a press (Fig. 3), whereupon the rods d are
introduced between the bands and the plates c. The whole bundle is now turned
over and again compressed and then another pair of rods d d are inserted between
the second plate c and the bands b. The cops are thus firmly compressed and form
a homogeneous mass of yarn without any hollow or empty space between them.
The packets formed in this manner are now treated in apparatus constructed as
shown in Figs. 4 to 8.
The arrangement illustrated by Figs. 4 and 5 is as follows;-A cylinder A is
arranged concentrically with another cylinder B so that an annular space g is left.
between the two. This space is closed at the top and connected at the bottom with
a suction or delivery pipe of a pump R. Radial receivers or receptacles C are
attached to the outer cylinder C in such a manner that the cylinder wall forms their
bottoms, the cylinder being perforated at the corresponding points. The open end
of each receiver is closed by means of a bent piece or yoke provided with a
perforated plate.
The packets of cops are placed in these receivers C and the liquid with which
the cops, spools or the like are to be treated is then introduced into the space g
between the two cylinders by means of the pump P. The liquid passes through
the perforated bottoms of the receivers C (formed by the cylinder wall B) and
penetrates the bundles of cops, after which it flows out again through the perforated
cover plates of the said receivers C and into a tank D which surrounds both the
cylinders A and B and the receivers C. It then may if necessary be caused by
the pump to pass through the cylinders and receivers once or several times more by
taking the course indicated by arrows in Fig. 5.
It will be understood that the liquid instead of being forced through the
receivers C may be caused to pass through them by suction.
It has been before stated that ready-made bundles of cops are placed in the
receivers C for the purpose of being treated in the manner just described. But
instead of preparing the bundles beforehand, the spools or cops may be placed into

page_text: the receivers C-singly and there combined and compressed into bundles, so that
after undergoing the required treatment they may be removed one by one.
The
first described method, of connecting them into bundles preparatory to the dyeing
or bleaching process, is however preferred.
Figure 6 is a modified arrangement of the receivers C wherein they are connected
with a hollow body of triangular section.
In another arrangement shown in Fig. 7 the receivers C are attached to the
suction or delivery pipe of the pump singly. The arrows indicate the direction of
the flow of liquid, while in another arrangement shown in Fig. 8 all the receivers C
are directly connected to the delivery pipe of the pump. The mode of operation
will be readily understood from the inspection of the drawings and the arrows
therein.
After the cops have been thus treated in the apparatus above described, each
receiver being supplied with one particular dye mordant or other liquid, which may
be caused to circulate through it any required number of times, the whole of the
apparatus .e. the whole series of receivers C is placed into a centrifugal drying
machine to be freed from moisture.
From the foregoing it will be apparent that this invention enables very large
quantities of yarn already wound upon spools or in cops, to be subjected to all the
usual dyeing, bleaching, washing and other operations and the whole process may
be completed without so much as touching the cops or spools after once forming
them into bundles. These therefore retain unaltered the desired shape or form
and the points of the cops especially are protected from any deformation.
It will be understood from the above description that the apparatus employed in
carrying out this invention is capable of many modifications the forms of apparatus
here described and illustrated being merely examples; the main point of the
process being that the ready-wound cops or spools to be treated are arranged in
rows and compressed into bundles and thus bodily submitted to the action of the
liquid or liquids in such a manner that the liquid in passing through each bundle
can take no other course than the one in which it comes into contact with each
fibre of the bundle.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,―
The treatment of yarn formed beforehand into spools or cops wound crosswise
with liquids gases or other agent for mordanting dyeing bleaching washing or other
like purpose the same consisting in placing the ready wound yarn in a receiver or
box of any suitable form or size pressing it on one or more sides and forcing or
drawing the liquids or gases through the compressed yarn so that they can take no
other course than that which brings them into contact with the fibres thereof in
the manner substantially as described.
