Improved Appliance for Dyeing and Bleaching Textile Staples,
Filaments, or Fibres on Tubes and Bobbins.
1, LEOPOLD KOENIG, Junior, of No. 6 Livland Street, St. Petersburg, Russia,
Spinning Mill Proprietor, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the method of dyeing and bleaching textile staples
filaments or fibres wherein these are wound upon perforated tubes or bobbins
which are slid over other perforated tubes communicating with a supply of the
dyeing or bleaching liquid, so that the latter is forced through the layers of the
filaments and thus effects the dyeing or bleaching thereof in a very uniform
manner.
According to my present improvement instead of making the perforated tube
or bobbin carrying the staple of such a size as to fit closely upon the perforated
supply tube as heretofore, I make the said tube or bobbin of larger internal
diameter than the supply tube with provision for fitting liquid tight on the upper
and lower parts of the latter so that a much freer passage is afforded for the
liquid and consequently a more effective action thereof on the staple is attained.
The improved construction is shewn on the accompanying drawing, which shews
the application to the dyeing or bleaching of rovings wound on bobbins ready for
spinning in fly frames.
a is the perforated supply tube fixed with its open end upon the supply pipe g
for the liquor, such tube being formed with a shoulder at the lower end and with
a threaded extension e on its upper closed end. Over this tube is fitted the
perforated bobbin ỗ on which is wound the roving. This bobbin is secured liquid
tight upon the tube, firstly by an internal circular shoulder f at the lower part,
which fits tight upon the shoulder of the tube, and secondly by a screw-nut c
which is screwed on to the threaded extension e and bears with the intervention
of a suitable packing ring d upon the upper end of the bobbin. Thus the liquor
passing through the perforated tube a fills the annular space intervening between
this and the bobbin and can thus penetrate freely through the entire perforated
inner periphery of this and into the roving.

I, LEOPOLD KOENIG, Junior, of No. 6 Livland Street, St. Petersburg, Russia,
Spinning Mill Proprietor, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to the method of dyeing and bleaching textile staples
filaments or fibres wherein these are wound upon perforated tubes or bobbins
which are slid over other perforated tubes communicating with a supply of the
dyeing or bleaching liquid, so that the latter is forced through the layers of the
filaments and thus effects the dyeing or bleaching thereof in a very uniform
manner.
According to my present improvement instead of making the perforated tube
or bobbin carrying the staple of such a size as to fit closely upon the perforated
supply tube as heretofore, I make the said tube or bobbin of larger internal
diameter than the supply tube, with provision for fitting liquid-tight on the upper
and lower parts of the latter so that a much freer passage is afforded for the
liquid and consequently a more effective action thereof on the staple is attained.
The improved construction is shewn on the drawing accompanying my provisional
specification which shews the application to the dyeing or bleaching of rovings
wound on bobbins ready for spinning in fly frames.
a is the perforated supply tube fixed with its open end upon the supply pipe 9
for the liquor, such tube being formed with a shoulder at the lower end and with
a threaded extension e on its upper closed end. Over this tube is fitted the
perforated bobbin b on which is wound the roving. This bobbin is secured liquid-
tight upon the tube, firstly by an internal circular shoulder f at the lower part,
which fits tight upon the shoulder of the tube, and secondly by a screw-nut c
which is screwed on to the threaded extension e and bears with the intervention
of a suitable packing ring d upon the upper end of the bobbin.
Thus the liquor passing through the perforated tube a fills the annular space
intervening between this and the bobbin and can thus penetrate freely through
the entire perforated inner periphery of this and into the roving.
It will be obvious that instead of leading the liquor through the pipe g tube a
and the roving from within outwardly, the liquor can also be made to pass in
the opposite direction, that is to say from the outside to within, by establishing
a vacuum or suction in the pipe g, the said devices being in that case immersed
in the liquor. In this case the above described annular space between the tube a
and bobbin 6 will act with equal advantage in causing a uniform distribution of
the sucking action throughout the roving. The liquor might also be made to
flow alternately in either direction, by producing alternately pressure and suction
in the pipe . By this means an exceedingly uniform action of the liquor on
the roving will be obtained.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what I
claim is:-
The herein described appliance for dyeing and bleaching staples filaments or
fibres while wound upon perforated tubes or bobbins, consisting of a perforated
tube or bobbin 6 on which the staple or filament is wound, and which is fitted
upon a perforated supply tube a in such a manner that an annular space is formed

page_text: between the two, which space is enclosed in a liquid tight manner, firstly, by the
bobbin 6 fitting with a shoulder f on a shoulder of the tube a and secondly by
a nut c screwing on to a threaded extension e of the tube a and fitting with
packing d against the top of the bobbin b, substantially as described.
