PROVISIONAL SPECIFICATION.
Improvements in Winches Suitable for Passing Hanks or Bundles of
Yarn through Liquids.
I, THEODOR EUGEN SCHIEFNER, of XI Grillgasse 6, Vienna, Austria, Factory-
Manager, do hereby declare the nature of this invention to be as follows:-
A winch according to this invention suitable for steeping, mercerizing, or dyeing
lanks or bundles of yarn will allow the hanks or bundles of yarn to be placed
easily and quickly in position for treatment, and will, whilst in operation, bring
all parts of the yarn in a uniform manner into contact with the steeping, mer
cerizing, or dyeing liquid.
The winch, which is arranged in a trough, whose upper part can be lifted off and
whose lower part can be raised and lowered, rests at one end in a bearing that can
be turned down and that enables the hanks of yarn to be placed in position for
treatment by sliding them sidewise upon the winch. The winch also is provided
with bars which are arranged parallel to its axis and which, during the rotation
of the winch, rotate about their axes and thereby impart to the hanks of yarn
wound around them, a movement in the direction of the fibres.
The accompanying drawings represent a winch according to this invention;
Fig. 1 is a longitudinal section, and Fig. 2 a sectional end elevation thereof, whilst
Fig. 3 shows the tensioning device of the winch in cross section.
The
The shaft a of the winch rests at one end in three fixed bearings a¹, and at its
other end in a bearing a² which can be swung outwards about a horizontal pivot
bolt on the framing, so that after lifting off the upper part, and lowering the
lower part b, of the vat that contains the steeping or mercerizing liquid or the
dyeing bath, the bundles or hanks of yarn to be treated can be slipped upon
the winch from one side. The winch is driven by means of a belt pulley e.
winch is provided with two or more longitudinal bars d which are cach furnished
with journals and are arranged parallel to the winch shaft, and which are pro-
vided on their peripheries with a number of ribs over which the hanks of yarn
are stretched. These longitudinal bars revolve with the winch shaft a and are
simultaneously rotated about their own axes.
For this purpose there is on each axle d'a chain-wheel ³, which is connected
by a chain with a wheel, which is prevented from rotating and is mounted
loosely on the shaft a. By means of this double movement, the hanks of yarn.
whilst they are alternately dipped into the bath and drawn out again in conse-
quence of the rotation of the winch, are moved onward in the direction of the fibres,
so that the parts of the yarn in contact with the winch bars are continually
changed and therefore all parts are subjected to the action of the bath in a uniform
manner.
For stretching the hanks of yarn located on the winch or for shifting the bars &
in accordance with the width of the hanks or bundles of yarn there is provided
a shaft a', which is arranged concentrically to the shaft and moves the radially
movable bearings of the winch bars d simultaneously outwards or inwards by

page_text: means of pairs of bevel-wheels and right and left hand screw-spindles a", the
winch bars d always remaining parallel to the shaft a.

Improvements in Winches Suitable for Passing Hanks or Bundles of
Yarn through Liquids.
I, THEODOR EUGEN SCHIEFNER, of XI Grillgasse 6, Vienna, Austria, Factory-
Manager, 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: -
A winch according to this invention suitable for steeping, mercerizing, or dyeing
hanks or bundles of yarn will allow the hanks or bundles of yarn to be placed
easily and quickly in position for treatment, and will, whilst in operation, bring
all parts of the yarn in a uniform manner into contact with the steeping, mer-
cerizing, or dyeing liquid.
The winch, which is arranged in a trough, whose upper part can be lifted off and
whose lower part can be raised and lowered, rests at one end in a bearing that can
be turned down and that enables the hanks of yarn to be placed in position for
treatment by sliding them sidewise upon the winch. The winch also is provided
with bars which are arranged parallel to its axis and which, during the rotation
of the winch, rotate about their axes and thereby impart to the hanks of yarn
wound around them, a movement in the direction of the fibres.
The drawings filed with my Provisional Specification represent a winch according
to this invention.
Fig. 1 is a longitudinal section, and Fig. 2 a sectional end elevation thereof,
whilst Fig. 3 shows the tensioning device of the winch in cross section.
The
The shaft a of the winch rests at one end in three fixed bearings a', and at its
other end in a bearing a which can be swung outwards about a horizontal pivot
bolt a³ on the framing, so that after lifting off the upper part, and lowering the
lower part b, of the vat that contains the steeping or mercerizing liquid or the
dyeing bath, the bundles or hanks of yarn to be treated can be slipped upon
the winch from one side. The winch is driven by means of a belt pulley c.
winch is provided with two or more longitudinal bars d which are each furnished
with axles d and are arranged parallel to the winch shaft, and which are pro-
vided on their peripheries with a number of ribs d over which the hanks of yarn
are stretched. These longitudinal bars revolve with the winch shaft a and are
simultaneously rotated about their own axes.
For this purpose there is on each axle d¹ a chain-wheel d³, which is connected
by a chain with a wheel d³, which is prevented from rotating and is mounted
loosely on the shaft a. By means of this double movement, the hanks of yarn
whilst they are alternately dipped into the bath and drawn out again in conse-
quence of the rotation of the winch, are moved onward in the direction of the fibres, 4
so that the parts of the yarn in contact with the winch bars are continually
changed and therefore all parts are subjected to the action of the bath in a uniform
manner.
For stretching the hanks of yarn located on the winch or for shitting the bars d
in accordance with the width of the hanks or bundles of yarn there is provided 50

page_text: a shaft a', which is arranged concentrically to the shaft a and moves the radially
movable bearings of the winch bars d simultaneously outwards or inwards by
means of pairs of bevel-wheels and right and left hand screw spindles a³, the
winch bars d always remaining parallel to the shaft a.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A winch suitable for steeping, dyeing, or mercerizing bundles or hanks of
yarn, provided with bars d, which are arranged parallel to the driving shaft a
of the winch, over which the bundles or hanks can be stretched, and which, during
the rotation of the winch, are rotated about their own axes so as to give to the
hanks a movement in the direction of the fibres and thereby to cause all the parts
of the bundles or banks of yarn to come into uniform contact with the bath."
2. A winch according to the preceding claim, in which the winch bars d are
provided on their peripheries with a number of ribs 2 adapted to serve as supports
for the bundles or hanks of yarn and to move them during the rotation of the
winch-bars d.
3. A winch according to Claim 1, in which chain-wheels
are provided on
the axles of the bars d and are connected by chains with non-rotating
wheels d for the purpose of rotating the bars d about their own axes during the
rotation of the winch.
4. A winch suitable for passing hanks or bundles of yarn through liquids, con-
structed, arranged, and operating as hereinbefore described with reference to and
shown in the drawings.
