Improvements in Machinery or Apparatus for Treating Yarn in
the Hank.
We, AUGUST MONFORTS, of München-Gladbach, Germany, Manufacturing
Engineer, and AUGUST BUCKMANN, of Odenkirchen, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
The use of machines as heretofore constructed for dressing or sizing yarn in
the bank, is attended by the disadvantage that the yarn does not become treated
uniformly partly because it lies for a long time upon the roller that carries it, and
partly because the parts that are wetted with the size are not changed with sufficient
rapidity.
This disadvantage is obviated by machinery or apparatus constructed according
to this invention.
The accompanying illustrative drawings represent a combined hank sizing and
wringing machine according to this invention.
Fig. 1 showing a section parallel to the driving shaft thereof,
Fig. 2 being a plan, and
Figs. 3 and 4 showing sections at right angles to the aforesaid driving-shaft.
Mounted on the frames A. A' of the machine is a driving shaft wo, which carries
driving-pulleys s and toothed wheels and ¹. The toothed wheel drives a
crank-shaft k through a toothed wheel. The crank-pin is prolonged in the
form of a bolt and serves to receive a roller a, which is connected to a toothed
wheel band over which the banks of yarn are laid. The toothed wheel b engages
in an internally toothed ring e fixed to the framing of the machine, and the roller a
is compelled, in addition to its motion about the axis of the crank-shaft d, to
rotate about its own axis, so that the various points of the periphery of the roller
describe hypocycloids.
In place of the internally toothed ring e there might be employed a toothed
wheel upon which the wheel would roll externally so that the teeth of the wheel b
would then travel in epicycloidal paths.
In sizing or dressing machines as heretofore constructed, the roller a is either
fixed to its pin or is simply arranged to be rotatable thereon, in which latter case
the hanks of yarn produce in it a very uncertain and irregular rotation about its
own axis. As the portions of yarn that are first immersed increase considerably in
weight-especially when heavy size or dressing is being used-these portions have
a tendency to remain in their low position; and the result is that the yarn comes
into contact with the size in a very irregular manner.
In consequence of the fact
that according to this invention the hanks of yarn in the size in the receptacle D
have imparted to them, in addition to the circular motion about the axis of rotation
of the crank d, also a simultaneous powerful positive movement around the roller
the size is stirred and caused to move in two different ways simultaneously. By
this means the deposition of the heavy constituents of the size upon the bottom of
the receptacle is prevented in a very effectual manner and a very uniform application
of the size is secured.
The apparatus shewn mounted on the frame A¹ is for squeezing the sized hanks
of yarn. This apparatus consists essentially of three rollers, g, h, anil i, whic
revolre about parallel axes. The roller g is mounted on a shaft k', which is carrie
on the frame A' and is driven through toothed wheels 2' 3 from the shaft. The
,

page_text: roller g is provided at its periphery with a semi-circular groove which serves for
the reception of the yarn to be squeezed. The roller is mounted on a stud on a
lever and is caused by a weight m to stretch the bank of yarn n, which passes
over and rests on the roller h. The roller i is surrounded by a caoutchouc ring
and is mounted below the roller g on a lever o; it can be pressed with any desire!
amount of force against the roller by means of an adjustable weight p.
order to squeeze hauks of yarn that have been charged with size on the roller u,
they are laid over the roller h, which is then depressed until the hanks can also be
placed around the revolving roller g. The liquid will thereupon be squeezed out
by the upwardly pressing roller i and flow back again to the deepest part of the
receptacle D.
In consequence of the round groove provided in the roller g, and of the rounded
roller i, tho space occupied by the hank of yarn between the rollers g and i is of
sickle-shape in cross section. This causes the hank of yarn to be uniformly
squeezed in an extremely effectual manner, which cannot be done either with
smooth rollers or with rollers provided with rectangular grooves.
By lengthening or shortening the time of revolution of the hank of yarn, more
or less liquid can be removed therefrom as desired.
By the use of the sliding weight p on the lever o the pressure upon the yarn can
be adjusted and regulated accurately at will, but the workman cannot increase this
pressure to such an extent as to damage the yarn.
Both the entire machine, and each of its two main constituent parts viz. that for
sizing and that for squeezing the yarn, are capable of being employed for washing,
mordanting, dyeing and bleaching.

Improvements in Machinery or Apparatus for Treating Yarn in
the Hank.
We, AUGUST MONFORTS, of München-Gladbach, Germany, Manufacturing
Engineer, and AUGUST BÜCKMANN, of Odenkirchen, Manufacturer, 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:
The use of machines as heretofore constructed for dressing or sizing yarn in the
hank, is attended by the disadvantage that the yaru does not become treated
uniformly partly because it lies for a long time upon the roller that carries it, and
partly because the parts that are wetted with the size are not changed with
sufficient rapidity.
This disadvantage is obviated by machinery or apparatus constructed according
to this invention.
The illustrative drawings filed with our Provisional Specification represent a
combined hank sizing and wringing machine according to this invention.
Fig. 1 showing a section parallel to the driving shaft thereof,
Fig. 2 being a plan, and
Figs. 3 and 4 showing sections at right angles to the aforesaid driving-shaft.
Mounted on the frames A A' of the machine is a driving shalt w, which carries
driving-pulleys s and toothed wheels and . The toothed wheel drives a crank-
shaft through a toothed wheel. The crank-pin f is prolonged in the form of

page_text: a bolt and serves to receive a roller a, which is connected to a toothed wheel b and
over which the hanks of yarn are laid. The toothed wheel b engages in an internally
toothed ring e fixed to the framing of the machine, aud the roller a is compelled, in
addition to its motion about the axis of the crank-shaft d, to rotate about its own axis,
so that the various points of the periphery of the roller describe hypocycloids.
In place of the internally toothed ring e there might be employed a toothed wheel
upon which the wheel b would roll externally so that the teeth of the wheel b would
then travel in epicycloidal paths.
In sizing or dressing machines as heretofore constructed, the roller a is either
fixed to its pin or is simply arranged to be rotatable thereon, in which latter case
the banks of yarn produce in it a very uncertain and irregular rotation about its
own axis. As the portions of yarn that are first immersed increase considerably in
weight-especially when heavy size or dressing is being used these portions have
a tendency to remain in their low position; ant the result is that the yarn comes
into contact with the size in a very irregular manner. In consequence of the fact
that according to this invention the hanks of yarn in the size in the receptacle D
have imparted to them, in addition to the circular motion about the axis of rotation
of the crank d, also a simultaneous powerful positive movement around the roller a,
the size is stirred and caused to move in two different ways simultaneously. By
this means the deposition of the heavy constituents of the size upon the bottom of the
receptacle is prevented in a very effectual manuer and a very uniform application
of the size is secured.
The apparatus shewn mounted on the frame A¹ is for squeezing the sized hanks
of yarn. This apparatus consists essentially of three rollers, g, h, and i, which
revolve about parallel axes. The roller g is mounted on a shaft k', which is
carried on the frame A' and is driven through toothed wheels from the
shaft w. The roller y is provided at its periphery with a semi-circular groove
which serves for the reception of the yarn to be squeezed. The roller his
mounted on a stud on a lever l and is caused by a weight m to stretch the hank of
yarn n, which passes over and rests on the roller h. The roller i is surrounded by
a caoutchouc ring and is mounted below the roller g on a lever o; it can be pressed
with any desired amount of force against the roller y by means of an adjustable
weight p. In order to squeeze hanks of yarn that have been charged with size on
the roller a, they are laid over the roller A, which is then depressed until the banks
can also be placed around the revolving roller g. The liquid will thereupon be
squeezed out by the upwardly pressing roller i aud flow back again to the deepest
part of the receptacle D.
In consequence of the round groove provided in the roller g, and of the rounded
roller i, the space occupied by the hank of yarn between the rollers g and i is of
sickle-shape in cross section. This causes the hank of yarn to be uniformly
squeezed in an extremely effectual manner, which cannot be done either with
smooth rollers or with rollers provided with rectangular grooves.
By lengthening or shortening the time of revolution of the bank of yarn, more
or less liquid can be removed therefrom as desired.
By the use of the sliding weight p on the lever o the pressure upon the yarn can
be adjusted and regulated accurately at will, but the workman cannot increase this
pressure to such an extent as to damage the yarn.
Both the entire machine, and each of its two main constituent parts riz. that for
sizing and that for squeezing the yarn, are capable of being employed for washing,
mordanting, dyeing and bleaching.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine or apparatus for treating yarn in the bank, a roller (a) adapte 1
to receive the banks of yarn and mounted so as to be capable of rotating on a
revolving crank-pin the said roller u having in addition to its circular motio.

page_text: about the crank shaft a compulsory or positive rotary motion about its own axis,
substantially as herein described for the purpose specified.
2. In a machine or apparatus for treating yarn in the bank the combination of
the rollers g and h, which receive and hold the hanks in a stretched condition, and
a convexly rounded pressing roller i, which enters the correspondingly concavely
rounded groove in the roller g, and squeezes in a uniform manner the bank of yarn
revolving in the said groove, substantially as described and shown.
3. In a machine for treating yarn in the hank the combination of a single roller a,
which receives the hanks of yarn, is mounted so as to be capable of rotating on a
revolving crank-pin and is positively rotated about its own axis, so that its
periphery possesses a cycloidal motion which is imparted to the hanks of yarn,
with the rollers g and h which receive and hold the hanks in a stretched condition,
and a convexly rounded pressing roller i which enters the correspondingly
concavely rounded groove in the roller g, and squeezes in a uniform manner the
hank of yarn revolving in the said groove, substantially as described and shown.
4. My improved machine for treating yarn in the hank constructed arranged
and operating as herein before described with reference to and shown in the
accompanying drawings.
