I, ALFRED WYSER, of Aaran, in the Republic of Switzerland, Dyer, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object an apparatus for mercerizing yarn, particularly
cotton yarn, in which the hanks of yarn are arranged on an adjustable reel which may
be axially rotated in a vessel or receptacle, annular pipes being arranged on the walls
of the vessel, which pipes are provided with small openings towards the centre of the
vessel so that the finishing or mercerising liquid or water may be ejected or sprinkled
on to the banks of yarn through the said openings in these pipes.
The apparatus it shown in the accompanying drawings as an example,
Figure 1 being a vertical section ;
Figure 2, a horizontal section on the line x-y, Figure 1;
Figure 3, a vertical section of the vessel without the reel;
Figure 4, an elevation of the reel alone.
a is a preferably vertical cylindrical vessel, the bottom of which carries a footstep b
for receiving a vertical shaft c which is mounted at the top in a bearing b¹ in the
removable cover al of the vessel. Outside the vessel the shaft c has a belt pulley c¹
or other means of driving it. The shaft has at its upper end close under the cover a¹
of the lid, a threaded part d and is surrounded by a sleeve e on which hinge pieces e¹
are mounted. On the hinge piece e¹, links e² are mounted which are attached to the
vertical reel spindles et also by means of hinges or hinge pieces es. A nut d¹ provided
with a hand wheel is mounted on the threaded part d of the shaft c, which nut
carries in a groove turned in it a ring provided with hinges d'. Links 3 extend
from these hinge pieces d² to the uppermost hinges of the reel spindles or bars et. A
vertical pipe f having a nozzle or mouthpiece f is attached to the sides of the
vessel a and from said pipe there branches a number of horizontally placed annular
pipes which are provided with small openings towards the centre of the vessel.
Finally the vessel a has also a discharge pipe g.
The reel device may together with the removable lid a¹ be withdrawn from the
vessel a.
If hanks of yarn be placed on the reel bars e and the nut d¹ screwed down,
the uppermost links d³ have a tendency to come into a horizontal position, the reel
bars are thereby somewhat raised and by means of the links e² lift the sleeve e
until the latter bears against the shoulder of the threaded piece d. The reel bars et
can then rise no further and on the nut d¹ being further screwed down the reel
bars e will be pressed apart so that the yarn is stretched.
The reel device contained in the vessel a in Figure 1 is shown in this stretched
condition. In order to remove the yarn again from the reel device, the nut d¹ is
screwed upwards. It thereby draws up with its ring the topmost links d³, the reel
bars et follow and the sleeve e with the links e² are pushed downwards so that the
reel bars e¹ are approached to one another. When the diameter of the reel device
has thus been made smaller, the yarn may be removed. Figure 4 shows the reel
device in such a position. When the yarn has been stretched on the reel device it
is again inserted in the vessel, the nozzle f¹ is connected with a pipe bringing the

the liquid spurts out of the openings of the pipes f2 on to all parts of the yarn. The
nozzle is then connected with a water pipe and the mercerizing liquid and its
residue are rinsed from out of the yarn. The liquid accumulating at the bottom of
the vessel may be discharged through the pipe g.
The most essential advantage of the apparatus herein before described consists in
that the yarn is exposed to no stretching and no movement, whilst it is possible to
mercerize the finest kinds of yarn as well as the so called Grant wheel (cotton hanks
reeled crosswise) without breaking the thread, that is to say the yarn remains entirely
flawless.

Apparatus for mercerizing or Finishing Yarn.
I, ALFRED WYSER, of Aaran, in the Republic of Switzerland, Dyer, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
This invention has for its object an apparatus for mercerising yarn, particularly
cotton yarn, in which the banks of yarn are arranged on an adjustable reel which may
be axially rotated in a vessel or receptacle, annular pipes being arranged on the walls
of the vessel, which pipes are provided with small openings towards the centre of the
vessel so that the finishing or mercerising liquid or water may be ejected or sprinkled
on to the hanks of yarn through the said openings in these pipes.
The apparatus is shown in the drawings accompanying the Provisional Specification
as an example,
Figure 1 being a vertical section ;
Figure 2, a horizontal section on the line x-y, Figure 1;
Figure 3, a vertical section of the vessel without the reel;
Figure 4, an elevation of the reel alone.
a is a preferably vertical cylindrical vessel, the bottom of which carries a footstep b
for receiving a vertical shaft c which is mounted at the top in a bearing b¹ in the
removable cover a¹ of the vessel. Outside the vessel the shaft c has a belt pulley c¹
or other means of driving it. The shaft has at its upper end close under the cover a¹
of the lid, a threaded part d and is surrounded by a sleeve e on which hinge pieces e¹
are mounted. On the hinge piece e¹ links e² are mounted which are attached to the
vertical reel spindles et also by means of hinges or hinge pieces e³. A nut d¹ provided
with a hand wheel is mounted on the threaded part d of the shaft c, which nut carries
in a groove turned in it a ring provided with hinges d². Links d³ extend from these
hinge pieces 2 to the uppermost hinges of the reel spindles or bars e¹. A vertical
pipe f having a nozzle or mouthpiece fi is attached to the sides of the vessel a and
from said pipe there branches a number of horizontally placed annular pipes f² which
are provided with small openings towards the centre of the vessel.
vessel a has also a discharge pipe g.
Finally the
The reel device may together with the removable lid a¹ be withdrawn from the
vessel a.
If hanks of yarn be placed on the reel bars e and the nut d¹ screwed
down, the uppermost links d³ have a tendency to come into a horizontal position, the
reel bars et are thereby somewhat raised and by means of the links e² lift the sleeve e
until the latter bears against the shoulder of the threaded piece d. The reel bars e

being further screwed down the reel bars e
will be pressed apart so that the yarn is stretched.
The reel device contained in the vessel a in Figure 1 is shown in this stretched
condition. In order to remove the yarn again from the reel device, the nut is
screwed upwards. It thereby draws up with its ring the topmost links d³, the reel
bars et follow and the sleeve e with the links e² are pushed downwards so that the reel
bars et are approached to one another. When the diameter of the reel device has
thus been made smaller, the yarn may be removed. Figure 4 shows the reel device
in such a position. When the yarn has been stretched on the reel device it is again
inserted in the vessel, the nozzle f¹ is connected with a pipe bringing the mercerising
liquid, the reel is caused to rotate by means of the belt pulley c¹ and the liquid
spurts out of the openings of the pipes f2 on to all parts of the yarn. The nozzle fl
is then connected with a water pipe and the mercerising liquid and its residue are
rinsed from out of the yarn. The liquid accumulating at the bottom of the vessel
may be discharged through the pipe g.
The most essential advantage of the apparatus hereinbefore described consists in
that the yarn is exposed to no stretching and no movement, whilst it is possible to
mercerise the finest kinds of yarn as well as the so called Grant reel (cotton hanks
reeled crosswise) without breaking the thread, that is to say the yarn remains entirely
flawless.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is
1. An apparatus for mercerising yarns, characterised by the arrangement of an
adjustable reel revolubly mounted on its axis in a vessel which is provided with a
sprinkling device, substantially as described.
2. An apparatus for mercerising yarn or yarns having an adjustable reel revolubly
mounted on its axis in a vessel provided with a sprinkling device, the supports of the
reel device being hinged both to a sleeve surrounding the spindle and also to the reel
bars and the upper part of the spindle being threaded on which threaded part a nut
provided with a hand wheel is mounted which carries in a groove a ring of hinge
pieces which are connected with the uppermost hinges by means of links, substan-
tially as described.
3. An apparatus for mercerising yarns having an adjustable reel which is mounted
revolubly on its axis in a vessel provided with a sprinkling device, said sprinkling
device consisting of annular pipes lying on the walls of the vessel and connected
with a main pipe, said device being provided with small openings facing towards the
middle of the vessel, substantially as described.
