3 Claims.
This invention relates to improvements in
steam, or steam and air, operated means for cir
culating liquids and for varying and reversing
the ?ow thereof in vats, tanks, containers and
5 similar vessels.
The object of the invention is to control the
circulation and direction of ?ow of the liquor in
a vat or tank without mechanical circulating gear
such as paddles, pumps or propellers.
10
According to the ‘invention the Vat or tank is
constructed with three ducts disposed at one or
both ends extending the full width and preferably
vertical.
The ?rst duct extends upwards from the level
16 or from below the level of the bottom of the ma
'terial in the vat or tank to above the level of the
‘top of the material, the second duct opens out
of the ?rst duct at or near the bottom thereof
and extending upwards into an elevated tank or
20 reservoir placed at a higher level than the vat
or tank and the third duct extends downwards
from the tank or reservoir to aposition below
the material in the vat or tank. A steam and air
injector and pipe with a longitudinal row of
25 nozzles or apertures and capable of being rotated
or oscillated about its axis is positioned at the
junction between the ?rst and second ducts
whereby according to the position of the perfo
rations or nozzles steam and ,air issuing into the
30 ducts will cause the liquor in the vat container to
circulate up either the ?rst duct over the top of
the material in the vat or tank, down through
the material to the bottom and thence back to
(Cl. 68-183)
bottom of the ducts showing the positionof the
apertured injector, steam and air pipe and .con
trolling ?ap when .the circulation of the liquid
.is up the ?rst duct.
Fig. 6 is a similar section showing the position
of the apertured injector, steam and .air pipe
and controlling ?ap when the circulation of the
liquid is in the reverse direction.
Fig. '7 is a transverse section showing the steam
and air injector pipe and the means of supplying
steam and air thereto.
Fig. 8 is a longitudinal section of a machine
showing circulating ducts at both ends, the
racks carrying the hanks and the cages being
formed as two separate units.

Fig. 11 is a section on line I l-l I ‘Fig. 9 show
ing the position of the securing means when plac- '
ing the stick in position.
Fig. 12 is a similar section showing the position
of the securing means locking the stick in posi
tion.
The machine may comprise .a vat or tank A, a
perforated grid a over and a perforated grid a1
under the goods and a rack ‘B to support the
sticks or rods b from which hanks or hose are
suspended or a cage of known construction to
30
contain the goods or loose material.
The vat or tank A is constructed with three
ducts D1, D2, D3 at one end as shown in Fig. 1
or both ends assho'wn in Fig. ‘8 extending the full
the bottom of the ?rst duct or circulate up the
35 second duct into the tank or reservoir, down the
width and a steam air injector D with a rotatably
third duct to the bottom of the vat or tank up
through the material therein and down the ?rst
tion of the ducts D1 and D2 capable of being
oscillated about ‘its axis to bring the perforations
d1 opposite the duct D1 or'D2 as desired. The
duct D1 opens at the top above the level of the
duct.
‘
A pivoted ?ap, damper or valve is preferably
4.0 ?tted at the bottom of the ?rst duct to close it
when the liquor is being circulated up through
the material and down the ?rst duct.
The invention will be described with reference
to the accompanying drawings in which it is
4
shown applied to a yarn dyeing machine in which
the yarn in the form of hanks is suspended from
sticks arranged transversely of the machine. In
these drawingsz-

Fig. 2 is a side elevation of the end ofthe ma
chine at which the ducts are arranged.
Fig. 3 is a plan of the same end of the machine.
Fig. 4 is an end elevation of the same end of
the machine.
55
Fig. 5 is a section on a larger scale through the
mounted perforated pipe d disposed .at thejunc
upper grid (1 ,andat or near the level of the liquor
Vat or tank A and opens at the bottom below the
level of the goods and the bottom grid al.
The duct D2 opens into the bottom end of the
duct D1 and extends upwards beyond it into .an
elevated tank E above the level of the liquor in
the vat or tank VA. The duct D3 extends down
wards from the elevated tank E below the ducts
D1 and D2 and joins the space in the vat or tank
A below the bottom grid a1 and the goods therein.
.A damper ?ap or valve F is pivoted at J‘ be
low the ducts D1 and D2 which is adapted to close
the duct ,D1 and join the two ducts D1 and D2
into one and enclose the perforated pipe at of the
steam air injector D within the ducts.
The duct ‘D1 is '?tted with a plate or flap G 65

,
preferably curved above the top to direct the ‘approximately V shape, the upper ends of the
liquor when ?owing up the duct over the top of
the goods being treated in the vat or container.
The outlet of the duct D2 which extends upwards
into the elevated tank E is preferably curved to
extend above and over the top of the duct D3
in the bottom of the tank E.
The injector D is mounted external to the vat
or tank A axial with the perforated pipe d and
10 is connected to a steam pipe H and air pipe K the
admission of steam and air thereto being con
trolled by valves h and k. A bye-pass pipe H1
connects the steam pipe H with the air pipe K
through which steam may be passed direct to the
15 perforated pipe (1 for the purpose of heating the
liquor in the vat A.
The perforated steam and air pipe d is carried
in suitable bearings in the side walls of the vat
or tank A and is ?tted to a hand lever M ex
20 ternal to the vat, by which it can be rotated or
oscillated to bring the apertures or nozzles d1 into
a position to direct the steam or steam and air
issuing therefrom either into the ?rst duct D1
or into the second duct D2. The ?ap or damper F
2,5
is connected by a link f1 with the perforated
pipe (1 to close the damper when the perforations
d1 are directed into the duct D2 and to open it
when the perforations d1 are directed into the
duct D1. Indicating means not shown may be
30 provided at the end of the perforated pipe d to
show the correct position thereof, for causing the
liquor to ?ow up each of the ducts D1, D2.
In operation when it is desired that the liquor
should be circulated in a downward direction
35 through the material in the vat or tank A the
perforated pipe d is turned with the perforations
d1 to direct the steam and air up the duct D1 and
the damper flap F is moved to open the duct at
the bottom and the pivoted curved plate over the
40 top thereof is moved to a position to direct the
liquor passing up the duct D1 over the top of the
material in the vat.
The liquor is thus caused to travel up the ?rst
duct D1, over the top of the material, down
45 through the material and back again to the bot
tom of the duct D1, the circulation being thus
maintained downwardly through the material.
When it is desired to reverse the flow of the
liquor through the material in the vat or tank A
50' the perforated pipe (1 is rotated with the perfora
tions d1 into a position to inject the steam and air
into the bottom of the duct D2 and the damper
?ap F is closed making a continuous circuit. The
injected steam and air now causes the liquor to
55 flow up the duct D2 into the elevated tank or
reservoir E from which it falls through the third
duct D3 to the space below the bottom of the vat
or tank A. It then passes up through the mate
rial therein and circulates down the ?rst duct D1
60 to the bottom thereof and again up the duct D2
and back down the duct D3. By changing the
position of the perforated pipe (11 and the damper
flap F the circulation of the liquor is again re
versed.
Each end of a dye stick bis supported by a
65
bracket N affixed to the side of the rack B. Each
bracket N is formed with a recess n of the same
shape as the underside of the stick b. A locking
bar P carried by a hinged plate P1 is arranged
above the sticks which after the latter have been
inserted into the recesses n in their supporting
brackets N can be pivoted downwards to cause
the bar to engage the top edges of the sticks and
hold the latter securely in the brackets.
The sticks b employed are preferably of V or
75
legs over which the yarn passes being curled or
bent inwards to form a curved support for the
yarn and the locking bar comes into engagement
with these curved supports to lock the sticks in
position.
The underside of each locking bar P is formed
with a series of recesses p, two corresponding to
the end of each stick b into which the curved
upper edges of the stick enter when the bar P is 10
in its locking position.
rl‘he hinged plate Pl carrying the locking bar P
is operated by a curved arm R extending out
wardly through the side of the rack 13 and pro
vided with means by which it can be locked with
the plate P1 in its uppermost position, in its low
est position engaging the sticks or in an inter
mediate position between the uppermost and low
est positions.
Such locking means comprise a
transverse slot or groove r in the curved arm 20
adapted to be engaged by the edges of a recess 1'1
or by a projection on a plate or arm S pivoted on
the outside of the rack B.
When placing the sticks b in position in the rack
B after they have been inserted through the 25'
hanks of yarn, the locking bar P at one end of the
cage is moved to and locked in its intermediate
position and that at the other end is moved to
and locked in its uppermost position.
One end of each stick b is slid endways into the 30
brackets at the end where the locking bar P is in
its intermediate position when it will be loosely
held between the bar P and the bracket and the
other end of each stick is then lifted over the edge
of the bracket N at the other end of the cage, or
receptacle into the recess 11 in the bracket, the
locking bar being sufficiently raised over the
bracket to allow of this movement of the end of
the stick. Both locking bars are then moved into
their lowest position to lock the ends of the sticks 40
and prevent any movement of the latter.
The invention is applicable to any container,
vat, tank or similar vessel in which a reversal of
direction of circulation of the liquid therein is
required but it is particularly applicable for use in
dye vats or tanks such as are employed for dyeing
or treating yarn in hank form, hose and other
small articles.
What we claim as our invention and desire to
protect by Letters Patent is:——
