PROVISIONAL SPECIFICATION.
Improvements in or relating to Dyeing Apparatus.
I, JULIUS OTTO OBERMAIER, of Lambrecht, Rheinpfalz, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to apparatus for steeping, dyeing, washing &c. yarn wound
in spools or into cops as it comes from the spinning frame.
The apparatus is especially intended to be used for carrying out my process for
dyeing yarn described in my former Patent No. 15000º.
A trough or reservoir serving to hold the dye is connected to a pump provided
with a suction and forcing pipe. A vessel which really forms the dyeing apparatus
is placed in the interior of the said trough. The vessel can be made either with
a square or rectangular base and can if desired be rigidly connected to the
reservoir. A second reservoir is provided in a more elevated position for receiving
the dye.
The dyeing vessel is divided by longitudinal & transverse partitions into a
number of square compartments. The central space between the longitudinal
partitions is closed at the top and bottom and is provided with an inlet at the
bottom for the delivery pipe of the pump. The transverse partitions are provided
with a central opening extending from top to bottom. The square shaped com-
partments are intended to contain the frames or blocks described in Patent
No. 15000. The said frames or blocks are placed vertically into the compart-
ments and rendered tight at the top and bottom by means of fibrous material and
covered in by a lid.
Central openings in the partitions are adapted to receive wedge shaped pieces for
the purpose of preventing the liquor from passing between the adjoining blocks or
between the blocks and the partition and the outer wall. The walls of the blocks
as well as the longitudinal walls of the vessel are provided with perforations.
After having placed the blocks in the said vessel the pump is started and forces
the dye or other required liquid through the delivery pipe into the central space.
From here it passes through the perforated walls and then forces its way through
the yarn contained in the blocks; it is prevented from passing between any of the
blocks and the walls of the vessel and finally escapes through the perforations in
the outer walls of the vessel into the reservoir from which it flows again into the
pump to be forced as before through the yarn.
As a modification, the transverse partitions may be dispensed with and the blocks
are then placed closely side by side in the vessel. In this arrangement it is only
required to render the two end blocks water tight with the outer walls so that the
dyeing liquor from the central space is again as in the previous case forced from
the centre towards the exterior.

page_text: I, JULIUS OTTO OBERMAIER of Lambrecht, Rheinpfalz, in the Empire of
Germany, 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 statement :-
This invention relates to apparatus for steeping, dyeing, washing etc. yarn wound
on spools or into cops as it comes from the spinning frame.
The apparatus is especially intended to be used for carrying out my process for
dyeing yarn described in my former Patent No. 15000 of 1892.
A tank or reservoir S serving to hold the dye liquor is connected to a pump P
provided with a suction and forcing pipe. A vessel B which really forms the
dyeing apparatus placed in the interior of the said tank. The vessel B can be
made either with a square or rectangular base and can if desired be rigidly con-
nected to the reservoir S. A second reservoir is provided in a more elevated
position for receiving the dye liquor.
The dyeing vessel or vat B is divided by longitudinal partitions a, cd and
cross-partitions ef, gh, ik into a number of square compartments m (Figure 1).
The central space D between the longitudinal partitions a b, cd, is enclosed at
the top and bottom, and provided at the bottom with an inlet R for the delivery-
pipe of the force-pump P. The two outer cross-partitions ef, ik, are each divided
into two parts by a central opening, extending from top to bottom. The square
compartments m are intended for the frames or blocks, described in Patent
No. 15000, and as shown in Figure 1. The said frames or blocks are placed
vertically in the said compartments, tightly packed above and below and closed at
top by a tightly fitting cover, under pressure.
The central vertical openings in the two outer cross-partitions are adapted to
permit the insertion of vertically wedge-shaped pieces (Figure 1), of the form
shown in Figure 3, between each pair of frames or blocks placed in adjacent
compartments, so that the said blocks can be wedged up tightly against the central
cross-partition gh, on the one side, and the outer or end wall of the dyeing vat B ;
at o Figure 1, on the other side. The longitudinal outer walls of B as well as the
two longitudinal partitions a b, c d are provided with numerous perforations for the
passage of the dye or other liquor.
After the frames or blocks have been placed in the compartments m, wedged
tightly up against each other therein, and otherwise packed and covered in tightly
in the manner described, within the dyeing vat B, the pump P is started and forces
the dye or other liquor employed through the delivery-pipe R into the central
chamber D, through the perforations in the partitions a b, c d and through the
frames or blocks in the cells m, permeating the yarn therein contained (inasmuch
as the upper and lower sides and the two ends are tightly packed against its
passage) and so through the perforations in the longitudinal walls of the dyeing
vat Binto the tank S, whence it is drawn again by the pump, and forced again
through the yarn; and thus the operation is repeated as long as necessary.
As a modification shown in Figure 2 the transverse partitions ef, g ħ and ik may
be dispensed with and the blocks are then placed closely side by side in the vessel B.
In this arrangement it is only required to render the two end blocks water tight
with the outer walls o as shown in Figure 2 so that the dyeing liquor from the
central space D is as in the previous case forced through the frames or blocks and
the yarn therein from the centre towards the exterior.

page_text: 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 ;-
1. A dyeing apparatus in which the frames and blocks are placed vertically in
compartments formed by partitions such as a b, c d, ef, gh, ik, in a vessel or vat
such as B and are permeated from the inside outwards by the dye or other fluid
forced into the intervening space in the dyeing apparatus the packing of the
frames or blocks against the walls of the vessel B and between one another being
effected by wedge-shaped pieces substantially as described and illustrated in the
accompanying drawings.
•
2. The modification of the apparatus described in Claim 1 consisting in an
arrangement wherein the cross-partitions ef, gh, ik are dispensed with and the
frames or blocks are set close against each other so that they only require packing
sideways against the walls of the dyeing apparatus B, which also secures their
fitting tightly against one another substantially as described and illustrated in
Figure 2 of the accompanying drawings.
