Improved Apparatus for Drying Filaments, Threads, or Yarns that
have been Dyed or Bleached on Tubes or Tubular Bobbins or
Beams.
I, 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:-
:-
This invention relates to an improved apparatus for drying filaments, threads or
yarns that have been dyed or bleached on tubes or tubular bobbins or beams, and
which I will describe with reference to the accompanying drawing, in which Fig. 1
shews a vertical section of the apparatus and Fig. 2 a sectional plan of the same.
The apparatus consists of a hermetically closing casing A fixed on a cast iron
or other metal frame and provided at top with a removeable cover g. Centrally
in this casing is a revolving fans and round this are arranged a series of rotatable
spindles a on which are mounted hollow perforated cylinders or beams & carrying the
dyed or bleached filaments and brought to the apparatus directly from the dyeing
apparatus. The spindle of the fan e as also those of the cylinders or beams & pass
through the cast iron frame fin the lower part of which they are provided with bearings.
The framing falso contains the driving gear for imparting rotary motion to the fan
and tubes, the fan spindle being driven direct by a belt. and pulley o, while the
spindles a and tubes b are driven from the fan spindle by means of spur
gearing h, hh.
The action of the apparatus is as follows:-Heated air is forced by any suitable
suitable known means into casing A through the branch inlet c, and passes thence
through the layers of filaments and the perforated tubes or beams b as on the left hand
side of Fig. 1, or through the perforated hollow spindles p carrying the filaments
that project radially from the hollow cylinder b, as shewn on the right hand side; on
passing into the interiors i of these tubes, beams or cylinders, the air escapes
downwards together with the moisture carried therewith from the filaments through
the tubes that are connected to and revolve with the spindles a, and that constitute
extensions of the tubes or cylinders b; at the lower ends of the air and moisture
issue into the space d whence they are led off through a conduit l. For forming an
air-tight joint between the tubes or cylinders b and the tubes k, the former are
provided at their lower end with a caoutchouc packing, seating on an annular
projection m of the tube k, while at the upper end the tubes, beams or cylinders b
are closed air-tight by means of a cap n fitting over the threaded upper end of the
spindle a and secured by a screw-nut on the latter, as shewn. The tubes 6 being
thus hermetically closed at the upper ends, the whole of the hot air entering A under
pressure is forced to pass through the layers of filaments as above described, by
which means, and by the accelerative action of the fan e, the drying of the filaments
is effected in so rapid and perfectly uniform manner as has never before been
attainable. In addition to this, a great saving of labour and consequent expense, such
as was hitherto requisite on account of the numerous manipulations neccessary is
obtained.

page_text: By the employment of the above described means, a most porfect and uniform
drying of the filaments is obtained so as to render possible the drying of the most
delicately tinted goods without fear of their becoming spottey or stripey, as frequently
occurs with the existing methods of drying.
The apparatus can also be so arranged that the warm air saturated with moisture
escaping at d, is drawn off by suction or partial vacuum, if the nature of the drying
operation should requre it.
As will be readily understood, the apparatus may be inade of such a size as to
operate simultaneously upon a large number of the tubes b so that a much greater
quantity of goods can be dried at one time than was heretofore possible.

Improved Apparatus for Drying Filaments, Threads, or Yarns that
have been Dyed or Bleached on Tubes or Tubular Bobbins or
Beame.
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
ascertained in and by the following statement :-
This invention relates to an improved apparatus for drying filaments, threads or
yarns that have been dyed or bleached on Lubes or tubular bobbins or beans, and
which I will describe with reference to the drawing accompanying my provisional
specification, in which Fig. 1 shews a vertical section of the apparatus and Fig. 2
a sectional plan of the same. The apparatus consists of a hermetically closing
casing A fixed on a cast iron or other metal frame f and provided at top with a
removable cover g. Centrally in this casing is a revolving fan e and round this are
arranged a series of rotatable spindles a on which are mounted hollow perforated
cylinders or beams 6 carrying the dyed or bleached filaments and brought to the
apparatus directly from the dyeing apparatus. The spindle of the fan e as also those
of the cylinders or beams & pass through the cast iron frame fin the lower part of
which they are provided with bearings. The framing falso contains the driving gear
for imparting rotary motion to the fan and tubes, the fan spindle being driven
direct by a belt and pulley o, while the spindles a and tubes b are driven from the fan
spindle by means of spur gearing h h' h².
The action of the apparatus is as follows:-Heated air is forced by any suitable
known means into casing A through the branch inlet c, and passes thence through
the layers of filaments and the perforated tubes or beams bas on the left hand side of
Fig. 1, or through the perforated hollow spindles 2 carrying the filaments that project
radially from the hollow cylinder b, as shewn on the right hand side; on passing
into the interiora i of these tubes, beams or cylinders, the air escapes downwards
together with the moisture carried therewith from the filaments through the tubes k
that are connected to and revolve with the spindles a, and that constitute extensions
of the tubes or cylinders b; at the lower ends of the air and moisture issue into the
space whence they are led off through a conduit l. For forming an air tight joint
between the tubes or cylinders b and the tubes k, the former are provided at their
lower end with a caoutchouc packing, seating on an annular projection m of the
tube k, while at the upper end the tubes, beams or cylinders b are closed air-tight by
means of a cap n fitting over the threaded upper end of the spindle a and secured

page_text: by a screw-nut on the latter, as shewn.
The tubes 6 being thus hermetically closed
at the upper ends, the whole of the hot air entering A under pressure is forced to
pass through the layers of filaments as above described, by which means, and by the
accelerative action of the fan e, the drying of the filaments is effected in so rapid
and perfectly uniform manner as has never before been attainable. In addition to
this, a great saving of labour and consequent expense, such as was hitherto requisite
on account of the numerous manipulations necessary is obtained.
By the employment of the above described means, a most perfect and uniform
drying of the filaments is obtained so as to render possible the drying of the most
delicately tinted goods without fear of their becoming spotty, or stripey, as frequently
occurs with the existing methods of drying.
The apparatus can also be so arranged that the warm air saturated with moisture
escaping at d, is drawn off by suction or partial vacuum, if the nature of the drying
operation should require it.
As will be readily understood, the apparatus may be made of such a size as to
operate simultaneously upon a large number of the tubes b so that a much greater
quantity of goods can be dried at one time than was heretofore possible.
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 :-
Apparatus for drying filaments of all kinds, consisting of a bermetically closed
casing A with removable cap g, within which casing are a number of axes or spindles a
arranged round a central fan e and on which are mounted hollow perforated cylinders
or beams b that carry dyed or bleached filaments to be dried and wound either
directly on the hollow perforated beans b or on hollow perforated spindles, tubes or
bobbins p projecting radially from the hollow cylinders b, the said axes a together
with the cylinders b and the fan e having rotary motion imparted to them, while by
the air pressure or exhaust produced in the casing, the moist air as also the water
passing from the filaments are caused to flow off through the tube and channel
substantially as described.
