page_text: pressed firmly against the clamps a¹, but always care is taken, that a certain play is
left open.
The size of same depends upon the material to be treated, upon the liquor, upon
the pressure, under which the same stands, and upon some further circumstances,
under which the whole treatment of the material is effected. In order to be able
to choose this size at will and conveniently, there are screws, wedges or other
elements, which allow of the choice of the interval between the perforated plates
and the clamps according to need.
In order to keep the drawing clear, the devices are left out as they are very
simple indeed.
The same refers to the following arrangement
:-
It is evident, that it will appear judicious not to place the moveable frames
directly into the box G, but outwardly and independently from the same to fill a
further moveable box with the frames and after the filling to place into the
box G, which conditions must be fulfilled here, will be explained afterwards more
exactly, when describing the proceedings.
"
The whole arrangement of the apparatus is still in so far remarkable, as the
liquor, even after the reversing has taken place, always run through the motor in
the same direction. The reversing has therefore not the slightest influence upon
the direction of rotation of the motor axis.
The moveable frame b can be used for every bobbin. The same consists essentially
of four fillets 1 and 2, laid together in rectangle, which are rendered hollow on
their inner side correspondingly.
The fillets 1 are bored out in such a manner, that they take up the end of the
bobbins exactly, whilst the fillets 2 are cut out in such a way, that the bobbins,
laying in a double row next to each other completely fill out the empty space
between the fillets (Figure 3).
The fibre to be employed for preparing the bobbin is wound upon a hollow paper
spindle, into which a massive spindle g of hard wood, caoutchouc etc. diminishing
towards the front is placed. The latter spindle has a shoulder h, which is placed
in a corresponding groove i of the frame.
When a whole frame is armed with these bobbins, the same are so firm, that
they are not able to get out of their positions accidentally.
Two frames following each other, do certainly not differ, but the same are so
placed, that the bobbins next to each other are always placed against each
other.
These moveable frames cannot only be employed at the above described, but also
at nearly all apparatuses of the kind; they are in so far already exceedingly
suitable, because they allow of taking out single rows of bobbins, during a certain
process, without disturbing the others.
An alteration of these frames is in so far remarkable, as it aims at the establish-
ment of a wall of bobbins of only one row. Such a frame is prepared in such a
way that only one side is provided with bores, whilst the opposite side is cut out
corresponding to the points of the bobbins.
The new process of the applicant is based upon the observation, that, if an
action of a liquor, being under pressure, takes place upon a whole charge, only
then the highest uniformity in the action of the liquor upon the fibre can be
reached; if by motion of the single layers, forming this charge, an opportunity
is offered for exchange of maxima and minima of the single resistances of this
charge.
The single stages of the process run in the following manner :-
The bobbins properly inserted into the moveable frame are placed with the frame
into a hox G or into a box-shaped case, the exterior form of which is so as to fit
exactly into the box G.
This box-shaped case is composed of two side walls and the bottom, the two other
side walls being replaced by a stop ledge or two perforated plates arranged at
each side. This case, which is charged with the frame carrying the bobbins quite

page_text: in the same manner, as the box G, is then introduced into the latter so as to fit
exactly into it and then firmly closed by a cover.
The liquid is therefore allowed to flow through the bobbin arrangement quite in
the same manner, as through the box G charged with bobbins. The case has for its
purpose to permit taking the frames all at once out of the apparatus, which is not
the case when the box G is directly charged with the frames carrying the bobbins.
As according to the circumstances it may occur in treating textile fibres that it
is necessary to fix the amount of the vibratory motion of the frames the box G or
the box-shaped case should be provided with a device for increasing or reducing the
amount of the said vibratory motion.
For this purpose each stop ledge a¹ may be provided with two adjusting screws,
which are adjusted before the apparatus is put in activity, and against which the
frames will strike, when they are pushed backwards.
By advancing these screws the play of the frames would be reduced and by
unscrewing increased. The same purpose can be obtained by means of wedges.
In the latter case, that box is inserted exactly into the box G, so that the bath
can only get through the material itself. Then the necessary interval for the
motion of the frames is fixed by suitable regulating devices and the bath is allowed
to enter on one side of the charge interrupted however by the reversing for the
moment, and the liquor introduced from the opposite side.
This is continued so long until the action of the bath has reached the desired
stage.
If the bath strikes upon the one side of the charge, the latter is thrown backwards,
the material is pressed together under the strong pressure and a certain resistance
is offered to the passage of the bath.
'
In the moment of reversing, the whole material expands, the single frames
withdraw a little from each other and a complete transferring of maxima and
minima of the single-resistances takes place, when the bath again arrives.
The charge is again thrown back, pressed together and thus a new,
but very
uniform resistance is offered to the bath; this is evident, if one takes into
consideration, that the bath, striking rectangularly to the longitudinal axis of the
bobbin, presses the material stronger together, first on one side then again on the
other and grants the same, if also only for a short period, a stronger expansion.
The most essential advantages of the new process are, besides those already
mentioned, firstly, that the material to be treated can be placed into the apparatus
in an entire, closed charge, formed by niechanical arrangements; secondly, that the
material is not pressed together by spindles etc. in a mechanical manner, whereby a
really everywhere uniform resistance can never be obtained, but corresponding to
the circumstances, given by the position and quality of the single bobbins, whereby
the most complete action takes place in so far as a correspondingly greater pressure
of the material corresponds to an increased quickness of the bath; thirdly, that
the flow of the bath can be pressed through the material in opposite direction,
whereby, in connexion with the moveable frames, a perfect security for an every-
where uniform penetration of the material is warranted, as with the reversing of
the direction of the flow and pressure an exchange of the points of the greatest
and smallest resistance in every single bobbin goes hand in hand and also the
bobbins, which are in the centre of the charge, are uniformly acted upon.
Attention is particularly drawn to the simplicity and clearness of the whole
arrangement.

laying in a double row next to each other completely fill out the empty space
between the fillets (Figure 3).
The fibre to be employed for preparing the bobbin is wound upon a hollow
paper spindle, into which a massive spindle g of hard wood, caoutchouc etc.,
diminishing towards the front is placed. The latter spindle has a shoulder h, which
is placed in a corresponding groove i of the frame.
When a whole frame is armed with these bobbins, the same are so firm, that they
are not able to get out of their positions accidentally.
Two frames following each other do certainly not differ, but the same are so

other.
These movable frames cannot only be employed at the above described, but also
at nearly all apparatuses of the kind; they are in so far already exceedingly
suitable, because they allow of taking out single rows of bobbins during a certain
process, without disturbing the others.
An alteration of these frames is in so far remarkable, as it aims at the
establishment of a wall of bobbins of only one row. Such a frame is prepared in
such a way, that only one side is provided with boxes, whilst the opposite side is
cut out corresponding to the points of the bobbins.
The new process of the applicant is based upon the observation, that, if an
action of a liquor, being under pressure, takes place upon a whole charge, only then
the highest uniformity in the action of the liquor upon the fibre can be reached,
if by motion of the single layers, forming this charge an opportunity is offered for
exchange of maxima and minima of the single resistance of this charge.
The single stages of the process run in the following manner :-
The bobbins properly inserted into the movable frame are placed with the frame
into a box G or into a box shaped case, the exterior form of which is so as to fit
exactly into the box G.
This box shaped case. is composed of two side walls and the bottom, the two
other side walls being replaced by a stop ledge or two perforated plates arranged
at each side. This case which is charged with the frame carrying the bobbins
quite in the same manner, as the box G, is then introduced into the latter so as to
fit exactly into it and then firmly closed by a cover..

page_text: The liquid is therefore allowed to flow through the bobbin arrangement quite
in the same manner, as through the box G charged with bobbins. The case has
for its purpose to permit taking the frames all at once out of the apparatus, which
is not the case, when the box G is directly charged with the frames carrying the
bobbins.
As according to the circumstances it may occur in treating textile fibres that
it is necessary to fix the amount of the vibratory motion of the frames the box G
or the box shaped case should be provided with a device for increasing or reducing
the amount of the said vibratory motion.
For this purpose each stop ledge a' may be provided with two adjusting screws,
which are adjusted before the apparatus is put in activity and against which the
frames will strike when they are pushed backwards.
By advancing these screws the play of the frames would be reduced and by
unscrewing increased. The same purpose can be obtained by means of wedges.
In the latter case, that box is inserted exactly into the box G, so that the bath
can only get through the material itself. Then the necessary interval for the
motion of the frame is fixed by suitable regulating devices, and the bath is allowed
to enter on one side of the charge, interrupted however by the reversing for the
moment, and the liquor introduced from the opposite side.
This is continued so long until the action of the bath has reached the desired
stage.
If the bath strikes upon the one side of the charge, the latter is thrown back-
wards, the material is pressed together under the strong pressure, and a certain
resistance is offered to the passage of the bath.
In the moment of reversing, the whole material expands, the single frames with-
draw a little from each other and a complete transferring of maxima and minima
of the single resistances takes place, when the bath again arrives.
The charge is again thrown back, pressed together, and thus a new, but very.
uniform resistance is offered to the bath; this is evident if one takes into considera-
tion that the bath, striking rectangularly to the longitudinal axis of the bobbin,
presses the material stronger together first on one side, then again on the other,
and grants the same, if. also only for a short period, a stronger expansion.
The most essential advantages. of the new process are, besides those already
mentioned, firstly, that the material to be treated can be placed into the apparatus
in an entire closed charge, formed by mechanical arrangements; secondly, that the
material is not pressed together by spindles etc., in a mechanical manner, whereby
a really everywhere uniform resistance can never be obtained, but corresponding
to the circumstances given by the position and quality of the single bobbins, whereby
the most complete action takes place in so far as a correspondingly greater pressure
of the material corresponds to an increased quickness of the bath; thirdly, that
the flow of the bath can be pressed through the material in opposite direction,
whereby in connexion with the movable frames, a perfect security for an every-
where uniform penetration of the material is warranted, as with the reversing of
the direction of the flow and pressure and exchange of the points of the greatest
and smallest resistance in every single bobbin goes hand in hand and also the
bobbins, which are in the centre of the charge, are uniformly acted upon.
Attention is particularly drawn to the simplicity and clearness of the whole
arrangement.
The characteristic feature of the above described invention is based upon the
fact, that contrary to the hitherto used methods for dyeing yarn in a copped
condition, the liquor passes across the bobbins in a direction perpendicular to the
longitudinal axis which amongst others admits the employment of impermeable
shells of any shape.
This property renders the new process particularly fit for dyeing charged warp-
beams; the Figures 6 to 9 of the drawing accompanying this Complete Specification,
show the manner in which this may be carried out.

page_text: The Figures 6 and 7 represent in longitudinal and cross section the box in
which the warp-beams are submitted to the action of the colouring matters; these
boxes are introduced in the manner shown in the Figures 1 and 2 of the drawings.
K are the warp-beams carrying on the front ends threaded shoulders E (see
detail Figure 8, section % of Figure 7). To these shoulders may be applied the
fittings necessary for the warping operation. The frames H are provided at G'
on two sides with recesses in such a manner, that the said shoulders of the warp-
beams can move therein. In the apparatus shown in the drawing there are 4 warp-
beams arranged in a frame, and after this has been done a frame-piece R (see
Figures 7 and 9 which is a section on the line X of Fig. 7) entering also the recess,
is applied as a closure. The next row is arranged in a displaced manner with
respect to the first (see Figure 1). After the box has been charged in such manner
with several rows of warp-beams a wedge L is inserted between the frame and the
one of the suitably sloped walls of the box so as to obtain a perfect tightening of
the frames on the walls. Before the wedge has been inserted the frames can
easily be introduced and withdrawn.
This manner of tightening may be applied also to the frames fitted with bobbins.
Having now particularly described and ascertained the nature of the said inven-
tion, (communicated to me as aforesaid) and in what manner the same is to be
performed, I declare that what I claim is :-
1. Process for treating textile fibres in form of bobbins with a liquor,
characterised by the arrangement of bobbins, inserted in rows into movable frames,
which, pressed together by the liquor, being under pressure, and striking now from
one and then from the other side, are however entirely discharged from pressure,
when the direction of the motion of the liquor is changed, and are enabled to freely
expand, substantially as set forth.
2. For carrying out the process protected by Claim 1, an apparatus characterized
by the arrangement of a box (G) easy of access for the liquor from the opposite
direction, in which the frames, freely movable and fitted with the bobbins, swing
to and fro between two latticed plates, under the influence of the liquor being under
pressure, substantially as set forth and shown in the accompanying drawing.
3. For carrying out the process protected by Claim 1, a movable frame (6) which
carries the bobbins on spindles, which are embedded with shoulders in corre-
sponding grooves of the frame, whilst the frame itself is worked out in such a
manner, that the bobbins placed therein completely fill same, substantially as set
forth and shown in the accompanying drawing.
4. The application of the above described process to the dyeing of charged
warp-beams in such a manner, that the warp-beams symmetrically arranged in
boxes are penetrated by the liquor from one side to the other perpendicularly to
the longitudinal axis, substantially as set forth and shown in the accompanying
drawing.
5. In the apparatus characterised by Claim 4 the more perfect tightening of the
frames on the walls of the box by means of a wedge inserted between the frame
and the one of the walls correspondingly sloped substantially as set forth and
shown in the accompanying drawing.
