Improvements in Apparatus for Treating Yarns or Threads with
Liquids.
I, Orio VENTER, Manufacturer, of Innere Klosterstrasse 13, Chemnitz, in the
Kingdom of Saxony, do hereby declare the nature of this invention to be as
follows
-
This invention relates to apparatus for washing, bleaching, mordanting or
dyeing textile threads o varns in the wound up condition, that is to say, in the
shape of bobbins, cops or similar bodies, in an open vessel, and more particularly
to the arrangement of the regulating float which is sometimes used in this kind
of apparatus The wound up textile material is placed in an open trough and
the liquid used for treatment is caused to pass through the same alternately by
pressure and by suction, the said liquid being contained in a receptacle situated
axially underneath the open trough mentioned above The liquid receptacle and
the trough are connected by a short tube which contains the upper end of a stand
pipe, situated in the axis of the liquid receptacle and having its lower end slightly
above the bottom of the same An upright tubular frame serving to cauy the
bobbins is mounted in the axis of the tough and extends through the bottom of
the same into the connecting tube
Across the upper edge of the trough is fixed a bridge-piece or beam provided in
the centre with a set-aciew adapted to press on the top of the said upright fiame,
in order to form a tight joint between the said frame and the bottom of the
trough To the top or upper flange of the upught pipe extending down into the
liquid reservoir are fixed a pan of vertical guide iods, so as to extend upward
into the tubular frame mentioned above and to guide the float situated between
the said guide iods, said float having the shape of an upright cylinder large
enough to fill the major portion of the space formed by the short connecting
tube and the tubulai fiame The lower end of the float is connected by a link
with a valve adapted to close the upper end of the stand and from the valve
extends downwards through the axis of the stand pipe a valve and connected near
the lower end of the same with a balance lever adapted to transmit the motion
of the float to a weighted bellciank lever which controls the position of a steam
valve or an air valve by an electio-magnetic or other suitable mechanism
The liquid vessel is closed on all sides, and connected at the bottom with a pipe
for charging it with liquid or for discharging the same
The float regulates automatically the valve mechanism during the interval
between the period, when the liquid is being forced through the material and the
period when the liquid is being sucked through the same
The construction may, however, be simplified, so that the float only serves to
automatically stop these functions In this case the valve 1od extending from
the float valve through the standpipe, has at its lower end another valve adapted
to close the lower end of the stand pipe when the float is in its highest position
If now the buoyancy of the float has been regulated by suitable weights, and the

page_text: liquid is pressed upward through the stand pipe, the inlet of the latter will be
closed after the float has arisen to a given height, and when the liquid is drawn
down into the liquid receptacle during the suction period, and the float conse-
quently descends, the float-valve will close the upper end of the stand pipe and
thereby stop the downward flow of the liquid The subsequent reversal of the
valves must be effected by hand This float valve or valve rod may be connected
with a bell or other device for indicating, when the standpipe has been closed
By arranging the float in the interior of the trough and of the short connecting
tube, as described, the waste space is diminished, and the same float may be used
for different troughs

Improvements in Apparatus for Treating Yarns or Threads with
Liquids
1, OTIO VENIER, Manufacturer, of Innere Klosterstrasse 13, Chemnitz, in the
Kingdom of Saxony, 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
-
This invention relates to apparatus for washing, bleaching, mordanting or
dyeing textile threads or yarns in the wound up condition, that is to say in the
shape of bobbins cops or similar bodies, in an open vessel, and more particularly
to the arrangement of the regulating float which sometimes used in this kind
ot apparatus The wound up textile material is placed in an open trough, and
the liquid used for treatment 18 caused to pass through the same alternately by
pressure and by suction, the said liquid being preferably contained in a receptacle
situated axially underneath the open trough mentioned above
In the accompanying diawings Fig 1 is a vertical section and Fig 2 a plan
of an apparatus embodying my invention, Figs and 4 represent details of
construction and Fig 5 a modification
The liquid receptacle 6 and the trough a are connected by a short tube which
contains the upper end of a stand pipe d situated in the axis of the liquid recep-
tacle A bell-shaped carrier e, on which the bobbin are mounted by means of
hollow spindles radiating from the same, is situated in the axis of the trough a
and extends downward through the bottom of the same into the connecting tube
The bobbin carile e is connected with the bottom of the receptacle a by means
of a packing ring and forms a hermetic Joint with the tube c
Across the upper edge of the trough is fixed a budge-piece or beam f provided
in the centre with a set screw gl adapted to press on the top of the said upright
canie e, in order to form a tight joint between the said cater and the bottom
of the trough. To the top or upper flange of the upright pipe d extending down into
the liquid reservoir are fixed a pan of vertical guide 1ods so as to extend upward
into the cane mentioned above and to guide the float h situated between the said
guide rods, said float having the shape of an upright cylinder large enough to
fill the major portion of the space formed by the short connecting tube and the
carlier e The lower end of the float is connected by a link with a valve
adapted to close the upper end of the stand pipe, and from the valve extends
downwards through the axis of the stand pipe a valve rod connected near the
lower end of the same with a balance lever and intermediate mechanism k¹³, m¹, m³,

page_text: adapted to transmit the motion of the float to a weighted bell-crank lever which
controls the position of a steam valve or an air valve by an electro-magnetic or
other suitable mechanism
The liquid vessel 18 closed on all sides and connected at the bottom with a
pipe for charging it with liquid or for emptying the same
The adjustable stops m', m³ forming part of the intermediate mechanism turn
the lever to the night or to the left, in other words, they reveise its position
according as the float rises or falls, and cause it to close the electric contact n'
orn, Fig. 4, which contacts form part of alternative electric circuits including
electro-magnets o¹ and o One of the said magnets is adapted to operate on the
steam valve p and the other on the vacuum valve 9, so that by closing one circuit
or the other, either the steam valve or the vacuum valve may be opened
The stops mm² are preferably so arranged, that the level of the liquid in the
open trough a varies only between the lines and y, Fig 1.
In some cases it is required to work with compressed an or other suitable gas,
instead of steam, for which purpose I have provided a valve r adapted to be
inserted into the electric circuit instead of the steam valve p
The valves g, P
and are mounted on a short pipe S Figs 1 to 3, connected with the receptacle
by a valve t, and with the tube by a valve u
The valve u is always closed, as long as the float hiemains in action, but when
at the end of the operation the whole of the liquid has been drawn from the
trough into the reservoir b, the valve connected with the float closes the
stand pipe d
The material mounted in the trough a may now be washed with water by
connecting the branch pipe with a water supply pipe and opening the valve u,
whereby the water is allowed to flow through the pipe into the bell-shaped
bobbin-care e, thence through the hollow spindles adiating from the said
carriei e into the bobbins and the trough a, fiom which it escapes through the
discharge tube 2¹ When the supply of water through the branch v has been
stopped, the water still remaining in the tube z and belle must be forced out
through the trough a and discharge pipe z¹, by admitting steam on compressed an
In the apparatus represented by Figs 1 and 4 the operation commences by
admitting steam oi compressed au through the pipe to the liquid contained
in the receptacle b, whereby the liquid is forced through the bell e, hollow spindles
and bobbins into the trough a When the level of the liquid in a, and conse
quently also the float h, has reached its highest position, the reversing
gear 1, m, m, will reverse the lever 1, thereby closing the steam valve p and
opening the vacuum valve g, in consequence of which steam or air will flow from
the receptacle b out through the tube 6, and liquid will return from the trough a
into the receptacle 6, until the valve has been closed by the float
The diagram Fig 4 represents the position of the reversing mechanism, when
the rod has risen and opened the steam valve p.
In some cases, where the material mounted in the trough a requires only a
short treatment, the mechanism for automatically reversing the flow of the liquid
may be omitted, and the function of the float & limited to the automatic closing of
the pipe d. In this case, illustrated by Fig 5, the valve rod k extending from
the float valve through the standpipe, has at its lower end another valve 10
adapted to close the lower end of the standpipe &, when the float is in its highest
position If now the buoyancy of the float h has been regulated by suitable
weights, and the liquid is pressed upward through the standpipe, the inlet of
the latter will be closed, after the float has risen to a given height, and when the
liquid is drawn down into the liquid receptacle during the suction period, and
the float consequently descends, the float valve will close the upper end of the
standpipe and thereby stop the downward flow of the liquid The subsequent
reversal of the valves must be effected by hand This float valve or valve rod
may be connected with a bell on other device for indicating, when the standpipe
has been closed.

page_text: As a rule, the float h will be adapted to close the foot valve w, when the liquid
in the trough a has risen to a given level, in order to prevent an overflow of the
trough
As illustrated by Fig 5, the float h may be surrounded by a tube h¹ extending
into the trough a, so that the liquid in the same cannot fall below a given level y,
in case the valve 218 leaking, and that consequently the vain lying beneath
the level will never be touched by atmospheric air during the process of dying
By arranging the float in the interior of the trough and of the short connecting
tube, as described, the waste space is diminished, and the same float may be used
for different troughs
Having now particularly described and ascertained the nature of the said
invention and in what manner the same 18 to be performed, I declare that what
I claim is:-
1 Apparatus for treating yarn, such as cops, bobbins, &c, with liquids in an
open vessel, having the characteristic feature that the regulating float h 18 situated
in the interior or axis of the bell-shaped carrier e supporting the material to be
treated, in order to save space, without increasing the weight or expense, substan-
tially as described
2 In apparatus for treating yains with liquids, the combination of a trough a
having a float situated in the interior of the bell canying the goods, with a liquid
receptacle situated beneath the said trough and connected with the same by a
short axial tube and, if requned, with an upward extension of the said tube, to
prevent the liquid from falling below a given level, substantially as described
3 Apparatus for treating yains with liquids, constructed and adapted to operate
substantially as described
