IMPROVEMENTS IN THE MANUFACTURE OF FIBROUS MATERIALS AND IN MACHINERY THEREFOR
Year: 1884

page_text: I HUGH MENTEE WARD of No 1 Upper Frank Street Ballymacarrett in the
County of Down in Ireland Flax mill manager do hereby declare the nature of
the said invention for IMPROVEMENTS IN THE MANUFACTURE OF FIBROUS MATERIALS
AND IN MACHINERY THEREFOR to be as follows:-
My Invention is applicable to yarns of various kinds when produced by what
is known as the wet process of manufacture.
The treatment of such yarns according to my invention consists in drying them
when under tension upon the reel during or after the reeling thereof from the
bobbins thereby saving time and labour avoiding crumpling or bruising of the yarns
by twisting the hanks while wet and the breakage of threads by shaking and
stretching when dried in hanks according to the methods now and hitherto
practised.
For this purpose I apply directly and closely to the yarn a blast of air introduced
under strong pressure and at high velocity through a tube or tubes passing along
the reel and having a number of perforations or slots to direct the air blast against
the cuts or hanks or a part or parts thereof.
The blast of air is driven into and through the tube or tubes by means of
ordinary mechanical appliances and when desired or required to be heated may be
drawn from a hot air chamber or passed over steam pipes placed inside the perforated
or Blotted tube or tubes.

I HUGH MENTEE WARD of No 1 Upper Frank Street Ballymacarrett in the
County of Down in Ireland Flax Mill Manager do hereby declare the nature of
THE DRYING OF WET YARNS AND IN
my invention for IMPROVEMENTS IN
APPARATUS THEREFOR and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention is applicable to yarns of various kinds when produced by what is
known as the wet process of manufacture.
The treatment of such yarns according to my invention consists in drying them
by subjecting them to an artificial current of air while under tension upon the reel
during or after the reeling or winding of them upon the swifts from the bobbins
thereby saving time and labour, avoiding the crumpling or bruising of the yarns
by twisting the hanks, while wet, and the breakage of threads by shaking and
stretching when dried in hanks, according to the methods now and hitherto
commonly practised.
For this purpose I apply directly and closely to the yarn while stretched upon
the swifts as already mentioned a blast or current of air introduced under pressure
and at high velocity through a tube or tubes passing along the reel and placed
under and preferably behind the swifts and having a number of perforations or
slots corresponding with the pitch of the bobbins from which the yarn is being
reeled or wound in order to direct the air blast or current against the cuts or
hanks or a part or parts thereof as they revolve opposite and past such perforations
or slots.
I may cause the air tube or tubes to traverse along the reel or swifts in
correspondence with the movement of the bobbins as now commonly actuated
Or instead of forming perforations or slots in the air tube I may fit it with a
perforated or slotted slide which would be caused to traverse in correspondence
with the bobbins along the reel.
The traversing movement of the air tube or slide is effected by means of a rack
attached thereto and worked by a pinion attached to a worm wheel actuated by a
worm on the bell-wheel shaft which is extended downwards for the purpose. But
I prefer to make the swifts move laterally and to keep the bobbins and air tubes
stationary so that the layers of yarn are distributed over the swifts and the air
blast or current is directed upon the portions of the hanks most recently wound
upon the swifta,
In order to accomplish the traversing movement of the swifts I employ hinged
racks gearing into the ordinary traverse pinions and connected by looped levers
with the axles of the swifta.
These axles being free to move laterally through the worms as required, it is only
necessary after the completion of the hanks to lift the hinged racks out of gear
with the traverse pinions and move the swifts back to position, placing the hinged
racks into gear with the traverse pinions again before repeating the winding
operation.

page_text: The blast of air is driven into and through the tube or tubes by means of
ordinary mechanical appliances and when desired or required to be heated may be
drawn from a hot air chamber which I prefer or may be passed over steam pipes
placed inside the air tube or tubes.
And in order that my said invention may be more fully understood I shall now
proceed to refer to the drawings upon the sheet hereunto annexed the same letters
of reference indicating the same or corresponding parts of my apparatus throughout
all the drawings.
Fig. I is a transverse section of an ordinary reel for winding yarn into hanks,
one swift being shewn open as in operation to receive the yarn from the bobbins
and the other swift being shewn closed as for the removal of the hanks.
Fig. II is a front elevation of a similar reel with the closed swift turned on its
side in order to give a view of one of the air tubes behind it.
Fig. III is a top detailed view of the air tubes.
Fig. IV is a detailed view of the motion for traversing the air tube or slide and
Fig. V is a detailed view of the parts of the motion for traversing the swift.
a, is an open swift receiving the yarn and a¹, is a swift which is closed for the
removal of the hanks after winding; b, b, are the bobbins from which the yarns
are wound into banks upon the swifts a and a¹; c, c, are the air tubes having
perforations or slots c³, c¹, corresponding with the pitch of the bobbins b, b, and
through which the air blast or current is directed against each portion of the hanks
as the swift revolves over the perforations or slots; e, is the rack attached to the
air tube or slide and gearing with the bell-wheel shaft f, by means of the worm g,
the worm wheel g³, and the pinion h; 1, is the hinged rack gearing into the traverse
pinions, and m, m, are looped levers connecting the hinged rack l, with the axles
of the swifts which move freely through the worm n.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
.
1. The drying of wet spun yarns while under tension upon a reel by the aid of
an artificial current of air substantially in the manner herein before described and
shewn by the drawings hereunto annexed.
2. The use of an air tube or air tubes arranged with perforations or slots or
with a perforated or slotted slide and employed substantially in the manner and
for the purposes herein before described and shewn upon the drawings hereunto
annexed.
3. The combination and arrangement of parts constituting my improved drying
apparatus constructed and employed substantially in the manner and for the
purposes herein before described and illustrated by the drawings hereunto annexed.
