Rotary Apparatus for Preparing for Dyeing and for Dyeing Combed
Wool in Bobbins.
We, LÉON HARMEL, JULES HARMEL and ALBERT HARMEL, Manufacturers, all of
Val-des-Bois, Commune de Warmeriville, near Reims (Marne) in the Republic of
France, do hereby declare the nature of this invention to be as follows :-
Our invention relates to apparatus for mechanically dyeing wool in bobbins as it
comes from the combing process, and also for subjecting it to all the preparatory
operations for that purpose, such apparatus having for its essential feature the
connection of the bobbiu-cylinders with perforated bottoms to one or more rotating
frames revolving in a vat containing dyeing liquor or other liquids.
For this purpose according to one arrangement, we provide in the vat or tank a
horizontal shaft to which a slow rotary motion is imparted by a worm and worm-wheel
or other gearing, and which is provided with radial arms that carry at their ends the
lateral trunnions of cylindrical receptacles, having perforated bottoms upon which the
bobbins of wool are placed so as to partly fill the receptacles, and upon the upper
surface of the bobbins are introduced perforated covers, that are held in position by
means of side bars passing up boyond the top of the receptacle, where they are provided
with handles, a più or rod being passed through holes in the receptacle and bars
for retaining the cover in place. These receptacles being suspended by their trunnions
on the arms of the rotating shaft, and their centre of gravity being situated below the
trunnions, they are made to maintain a vertical position as they revolve with the shaft,
so that in dipping into the liquid in the vat the receptacle becomes filled therewith in
the space above the cover, so that on the vessel being raised out of the vat, this body
of liquid is made to percolate through the bobbins and perforated bottom and fall back
into the vat, such operation being repeated at every revolution.
According to another arrangement the receptacles are fixed rigidly to the arms of
the revolving shaft so that their ends are presented in the direction of rotation, that is
to say in positions at right angles to the radial arms. The perforated bottom is
situated some distance within the one end, and the removable cover some distance
within the other end, being held in place by a screw and intermediate spring. On

page_text: rotation being imparted to the shaft in one direction or the other by worm or other
gearing, the receptacles are moved round in the liquor with the one or the other of
their open ends presented in the direction of motion so that the liquor percolates
through the contents thereof, until the wool is sufficiently acted upon. If necessary,
the shaft is rotated first in one direction and then in the other so as to cause the liquor
to penetrate alternately in both directions.
In connection with the vat in either of the above arrangements is a tank in which
the dye or other liquor is prepared, and from which it is conveyed when required, into
the vat either by steam or other pressure acting upon the confined liquid so as to force
it through pipes into the vat, or by pumps, injectors or other means.
According to one arrangement for this purpose, the tank communicates at bottom
through a valve with a pipe leading at one end to a discharge cock, for emptying the
tank when required, and at the other end to a closed recipient, whoso upper end
communicates with a steam pipe, and whose lower end communicates with a vertically
rising pipe leading into a horizontal pipe leading on the one hand over the dyeing vat
and on the other hand over a trough leading over the tops of a series of the preparing
tanks and capable of communicating with each through a valve. The recipient also
has a branch pipe connected with the bottom of the dyeing vat.
When the bobbins have been placed in their receptacles in the vat as above described,
and the preparing tank is charged with liquor, the latter is put in communication with
the closed recipient, which, when full, has steam admitted to it so as to discharge its
contents into the vat, this operation being repeated as often as necessary.
After the bobbins have been subjected to the action of the liquor for the required
time, the communication between the dyeing vat and the recipient is opened, so as to
allow the liquor to flow back into the latter, steam being then admitted to the recipient
so as to cause the liquor to flow into the before mentioned trough which conducts it to
one or other of the preparing tanks.

Wool in Bobbins.
We, LÉON HARMEL, JULES HARMEL and ALBERT HARMEL, Manufacturers, all of
Val-des-Bois, Commune de Warmeriville, near Reims (Marne) in the Republic of
France 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 :-
Our invention relates to apparatus for mechanically dyeing wool in bobbins as it
comes from the combing process, and also for subjecting it to all the preparatory
operations for that purpose, such apparatus having for its essential feature the
connection of the bobbin cylinders with perforated bottoms to one or more rotating
frames revolving in a vat containing dyeing liquor or other liquids.
For this purpose according to one arrangement shewn in end view by Fig. 1 and in
longitudinal section by Fig. 2 we provide in a vat or tank Fa horizontal shaft A to
which a slow rotary motion is imparted by a worm wheel and worm G driven from
pullies H' or other gearing, and which is provided with radial arms B that carry in
bearings a at their ends the lateral trunnions b of cylindrical receptacles C having
perforated bottoms c upon which the bobbins of wool are placed so as to partly fill the
receptacles, and upon the upper surface of the bobbins are introduced perforated
covers c' each of which is held in position by means of side bars d passing up beyond
the top of the receptacle where they are provided with handles, a pin or rod e being
passed through holes in the receptacle and in the bars d for retaining the cover in place.
These receptacles, being suspended by their trunnions 6 on the rotating arms B and,
the centre of gravity of oach being situated below its trunnions, maintain a vertical
position as they revolve with the shaft, so that in dipping into the liquid in the vat F
each receptacle becomes filled with liquid in the space above the bobbin cover c², so
that on the receptacle being raised out of the vat, this body of liquid percolates through
the bobbins and perforated bottom and falls back into the vat, such operation being
repeated at every revolution.
According to another arrangement shewn in longitudinal and transverse section
respectively by Figs. 3 and the receptacles Care fixed in rings n to arms on a
shaft B' caused to revolve by a wheel O and pinion Q on a shaft R driven by
pullies H H. Thus the ends of the receptacles are presented in the direction of
rotation. The perforated bottom c of each is situated some distance within the one
end, and the removable cover c¹ some distance within the other end, being held in
place by a screw T and intermediate spring S. On rotation being imparted to the
shaft B in either direction the receptacles Care moved round in the liquor with the
one or the other of their open ends presented in the direction of motion, so that
the liquor percolates through the contents thereof, until the wool is sufficiently acted
upon. If necessary the shaft is rotated first in one direction and then in the other so
as to cause the liquor to penetrate alternately in both directions.

page_text: In connection with the vat in either of the above arrangements is a tank in
which the dye or other liquor is prepared, and from which it is conveyed, when
required, into the vat either by steam or other pressure acting upon the confined
liquid so as to force it through pipes G'into the vat F or it may be by pumps injectors
or other means.
According to the arrangement for this purpose shewn in Fig. 3 the tank H com-
municates at bottom through a valve y with a pipe G' leading at one end to a discharge
cock I for emptying the tank when required, and at, the other end to a closed
recipient N the other end of which communicatos through a cock 5 and branch pipe 4
with a steam pipe V and the lower and communicates by an ascending pipe 1 and
valve X with a horizontal pipe leading on the one hand, Y, over tho dyeing vat F
and on the other hand, Z, over a trough M over a series of the preparing tanks H
and capable of communicating with each through a valve. The recipient N also
has a branch pipe W connected with the bottom of the dyeing vat F which is also
furnished with a perforated steam pipe U.
When the bobbins have been placed in their receptacles in the vat as above described
and the preparing tank is charged with liquor, the latter is put in communication with
the closed recipient N from which air escapes by a cock G. When N is full, steam is
admitted to it so as to discharge its contents into the vat F this operation boing
repeated as often as necessary.
After the bobbins have been subjected to the action of the liquor for the required
time, the communication between the dyeing vat F and the recipient N is opened, so
as to allow the liquor to flow back into the latter, steam being then admitted to the
recipient so as to cause the liquor io flow into the trough M. which conducts it to one
or the other of the preparing tanks H or to a discharge.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we claim in
respect of apparatus for preparing for dyeing and for dyeing combed wool in
bobbins, is :-
1. In combination with a liquor tank and a horizontol revolving shaft and its arms,
vessels mounted on trunnions on these arms and containing between perforated
bottoms and covers the bobbins to be treated, arranged and operating substantially as
described with reference to Figs. 1 and 2.
2. In combination with a liquor tank and a horizontal revolving shaft and its arms,
vessels fixed on these arms and containing, between perforated bottoms and covers subject
to spring pressure, the bobbins to be treated, arranged and operating substantially as
described with reference to Figs. 3 and 4.
3. In combination with a liquor tank in which vessels containing bobbins revolve
in manner referred to in the preceding claims, tanks for preparing liquor with an inter-
mediate recipient and steam and liquor pipes with suitable cocks and valves arranged
