PROVISIONAL SPECIFICATION.
Improvements in the Method of and Means employed for Bleaching,
Dyeing, and otherwise Treating Flax, Hemp, and other Fibres.
I, ADAM MOMEEKIN of The Cogry Flax Spinning Company, Cogry Mills,
Doagh, Ireland, Mill Manager do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in the method of and means employed
for bleaching, dyeing, cleaning, drying and otherwise treating, flax, hemp and
other fibres, previous to their being spun into yarn, and whilst in the form of
"
rove and on the bobbin or tube.
"
According to this invention the "rove" is built or wound onto bobbins or tubes
which are perforated and, through such perforations the bleaching or other liquor
or hot air is forced from the inside by pressure which is supplied by a force pump
or other device, or the bobbins or tubes carrying the rove to be treated, can be
placed in a closed tank which communicates with a source of pressure by which
the rove is impregnated with bleaching or other liquor or hot air.
In like manner after bleaching or other treatment the rove can be washed or
otherwise cleaned by forcing through it water, or other neutralizer so as to free it
from all trace of acid which if. left in would be injurious to the material.
Separate pumps may be used for the different sorts of liquor, or one pump can
be made to communicate by a suitable arrangement of pipes, with the tanks
containing the several varieties.
Vulcanite, metallic, or other suitable bobbins or tubes, may be used for carrying
the rove, which may be built thereon in the form of a cop.

COMPLETE SPECIFICATION.
Improvements in the Method of and Means employed for Bleaching,
Dyeing, and otherwise Treating Flax, Hemp, and other Fibres.
I, ADAM MCMEEKIN, of The Cogry Flax Spinning Company, Cogry Mills,
Doagh, Ireland, Mill Manager, 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 improvements in the method of and means employed
for bleaching, dyeing, cleaning, drying, and otherwise treating flax hemp, and
other fibres, previous to their being spun into yarn and whilst in the form of "rove
and on the bobbin or tube.
According to this invention the "rove" is built or wound onto bobbins or tubes,
which are perforated, and through such perforations the bleaching or other liquor
or hot air is forced from the inside by pressure, which is supplied by a force pump
or other device, or the bobbins or tubes carrying the rove to be treated, can be
placed in a tank which communicates with a source of pressure, by, which the rove
is impregnated with bleaching or other liquor or hot air.

page_text: In like manner after bleaching or other treatment, the rove can be washed or
otherwise cleaned by forcing through it water, or other neutralizer, so as to free it
from all trace of acid, which if left in, would be injurious to the material.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings
in which:-
Fig. 1 is a side elevation of improved apparatus for treating flax, hemp, and
other fibres whilst in the form of rove "and on the bobbins or tube.
Fig. 2 is a plan view of Fig. 1.
<
Fig. 3 is a sectional end elevation of Fig. 2.
"
According to this invention the "rove "is built or wound onto bobbins or
tubes 1.1 of the ordinary shape, but perforated as at 2.2 and through these
perforations 2.2 and through the " rove on the bobbins or tubes the bleaching,
or other liquor, or hot air is forced from the inside by pressure which is supplied
by a force pump or other device.
The improved apparatus for treating the rove in the manner hereinbefore
described, consists of a tank 3, having a central pipe 4, on each side of which are
short branch pipes or outlets 5.5 on which are rubber or leather washers or
collars 6. 6. At each side of the pipe 4 is a rail 7 carried on guide rods 8.8 fixed
to the side of the tank 3, and such rails 7 can be moved nearer to or further from
the pipe 4 by means of the screwed rods 9.9 which are turned by the hand
wheels 10. 10 outside the tank 3. On the rails 7. 7 and opposite to the outlets 5.5
short plugs or studs 11. 11 on which are the rubber or leather washers 12. 12.
The bobbins or tubes 1. 1 are placed on the short branch pipes, or outlets 5.5 so
that the latter enter the centre holes of such bobbins, or tubes, and the opposite
ends of such bobbins, or tubes rest on the moveable supports 13. 13 (see Fig. 3)
and the rails 7.7 are then moved towards the centre pipe 4 until the plugs 11.11
enter the centre holes of the bobbins, or tubes, and the latter are held between the
pipe 4, and the rails 7.7 and the washers, or collars 6. 6 12. 12 by being pressed
tightly against the ends of the bobbins, or tubes no liquor or hot air can escape
except by way of the perforations 2.2 and so through the " on the bobbins,
or tubes.
rove
"
The pipe 4 is connected, at one, or both ends, to a force pump by which the
liquor, or hot air is forced through the perforations 2.2 and rove and the liquor
then falls into the tank 3 and can be withdrawn either by way of the discharge
pipe 14 which communicates with the cistern containing the bleaching liquor, or by
the pipe 15 to the cistern for water or other neutralizer, the pipes 14. 15 being
provided with valves so that they may be " open or "shut" as required.
"
Separate pumps may be used for the different sorts of liquor, or one pump can
be made to communicate, by arrangement of pipes with the tanks containing the
several varieties.
rove
*
"
Vulcanite, metallic or other bobbins or tubes may be used for carrying the
" which may be built thereon in the form of a cop and it will be evident
that the fibres whilst in the form of rove afford facilities for efficacious
bleaching, dyeing and otherwise treating the same as compared with like operations
performed on yarns as the fibres in the latter case are more condensed and not so
susceptible to the action of ingredients used nor to the speedy and thorough
permeation effected on fibres in rove.
Having now particularly described and ascertained the nature, and object of the
said invention, and in what manner the same is to be performed I declare that
what I claim is :-
1. The bleaching, dyeing and otherwise treating flax, hemp, and other fibres in
the rove by means substantially as herein described.
2. The improved apparatus herein described and illustrated wherein is comprised
a tank having a central, or main supply pipe 4 and branch pipes or outlets 5

page_text: provided with rubber, or other sealing washers such as 6 and adjustable rails 7. 7
all combined and for purpose of operating on fibres whilst in "rove" for purpose
set forth.
