the like.

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street
Manchester, both in the County of Lancaster and 323 High Holborn in
the County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the process for dyeing cotton yarn, slivers or roving,
described in Patent 17872 of November 6th 1890, and it has for its object an
improvement in the drying process which follows the dyeing, by the use of a
peculiarly constructed reel or spool.
As described in the former Patent No. 1787200 when the dyeing or bleaching of
the roving, or sliver, has been completed, the latter is formed into hanks and the
water removed by means of a centrifugal or squeezing machine, after which the
sliver may be dried in hanks and placed in cans or wound on spools, or it may be
wound off from the hanks into the spinning can frames after it has been freed from
water but whilst still damp, and not be dried until it is in the cans.
In the present improved process in contrast to the above, the dyed or bleached
yarn hanks, when the dyeing or bleaching is completed, are no longer coiled in
the cans in a dried or damp condition, but are wound whilst still quite wet, by
means of any suitable mechanical device on a reel which is peculiarly constructed
with a view to the subsequent drying process as will be hereinafter more
particularly described.
The roving is then dried on these reels and placed on the frame of a flyer, in
order to be then further treated.

The form of this reel is shown on the accompanying drawing, in which

Figure 2 a plan of the reel.

number of bars a made of any suitable material such as wood, vulcanite, papier,
maché or the like are arranged longitudinally on the outside of the spiral in such a
way that the spiral as shown in Figure 2 is passed through the inside of the bars.
For this object the bars a consist of two parts fitting longitudinally one upon the
other, and provided with grooves for receiving the wire spirals, and they are laid
from the outside and inside against the wire spiral and against one another in such
a way that they may be connected by means of glue, screws, rivets or the like, in
other words by means of any suitable means of fastening.
In choosing materials for making the bars care must be taken that they give the
reel sufficient rigidity whilst not allowing during their constant contact with
moisture their surface to become oxidised.
A reel made in the manner herein before described allows of any hanks of dyed
roving wound thereon to be rapidly and thoroughly dried, as in consequence of the
open or skeleton arrangement of the reel the air has unimpeded access to the
roving from both the interior and exterior of the reel. The winding of roving on

berein before described are employed, than is the case with the existing method of
winding the dried or damp hanks in cans.
Whilst under the old process for instance an operative could turn out under
favourable circumstances 100 kilogrammes, by the improved process hereinbefore
described he or she could on an average turn out 150 kilogrammes.

VUMILIE DIECIFICATION.
Improvements relating to the Drying of Dyed Cotton Yarns and
the like.
A communication by THEODOR SALZMANN, of Dornbirn, Vorarlberg, in the Empire
of Austria, Manufacturer.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 the process for dyeing cotton yaru, slivers or roving,
described in Patent No. 17872 of November 6th 1890, and it has for its object an
improvement in the drying process which follows the dyeing, by the use of a
peculiarly constructed reel or spool.
As described in the former Patent No. 178720 when the dyeing or bleaching of
the roving, or sliver, has been completed, the latter is formed into hanks and the
water removed by means of a centrifugal or squeezing machine, after which
the sliver may be dried in hanks and placed in cans or wound on spools, or it may
be wound off from the hanks into the spinning can frames after it has been freed

In the present improved process in contrast to the above, the dyed or bleached

cans in a dried or damp condition, but are wound whilst still quite wet, by means
of any suitable mechanical device on a reel which is peculiarly constructed with
a view to the subsequent drying process as will be hereinafter more particularly
described. .
The roving is then dried on these reels and placed on the frame of a flyer, in
order to be then further treated.
The form of this reel is shown on the drawing accompanying the Provisional
Specification, in which,
Figure 1 is an elevation, and
Figure 2 a plan of the reel.

suitable number of bars a made of any suitable material such as wood, vulcanite,
papier maché or the like are arranged longitudinally on the outside of the spiral
in such a way that the spiral, as shown in Figure 2, is passed through the inside
of the bars. For this object, the bars a consist of two parts fitting longitudinally
one upon the other, and provided with grooves for receiving the wire spiral, and
they are laid from the outside and inside against the wire spiral and against one
another in such a way that they may be connected by means of glue, screws, rivets
or the like, in other words by means of any suitable means of fastening.

page_text: In choosing materials for making the bars, care must be taken that they give the
reel sufficient rigidity whilst not allowing during their constant contact with
moisture their surface to become oxidized.
A reel made in the manner herein before described allows of any hanks of dyed
roving wound thereon to be rapidly and thoroughly dried, as in consequence of the
open or skeleton arrangement of the reel the air has unimpeded access to the roving
from both the interior and exterior of the reel. The winding of roving on the
bobbins is done much more rapidly when reels constructed in the manner
herein before described are employed than is the case with the existing method of
winding the dried or damp hanks in cans.
For winding the banks of roving on these improved reels a machine is employed
of similar construction to a winding machine (or warp winding frame). The reels
are placed directly on the spindles of this machine and receive from them a rotary
motion which allows the hanks of roving to be wound on the reels in tapering
layers, the thread guide mechanism being arranged accordingly. The reels when
filled are then dried and subsequently placed on the holding spindles of the middle
or flyer frame from which the roving undergoes the further spinning processes
generally employed in the cotton industry until it is converted into cops.
Whilst, under the old process, for instance, an operative could turn out under
favourable circumstances 100 kilogrammes, by the improved process hereinbefore
described he or she could on an average turn out 150 kilogrammes.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is-
1. In the process such as described in Patent No. 178720 for dyeing cotton yarn
or the like, the winding of the hanks of roving, after the dyeing, on revolving
skeleton reels with the object of enabling the air to have freer access, and of
thereby causing the roving to be more rapidly dried, substantially as bereinbefore
described.
2. With the object of carrying out the process described in Claim 1, the use of
reels formed of a cylindrical wire spiral 6 with bars a made of any suitable
material arranged on the said spiral, parallel to the axis of the reel substantially
as hereinbefore described and shown.
