PROVISIONAL SPECIFICATION.
Improvements in Machines for Finishing Yarn in the Form of
Hanks or Skeins.
I, AUGUST MONFORTS, of Munchen-Gladbach, Germany, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a machine for brushing and stretching yarn in the form
of hanks or skeins, in which flat brushes are employed whose bristles pass between
the threads from outside and inside the bank or skein (hereinafter referred to as a
hank) whilst the latter is at rest, and brush the same for a long or short distance as
required, and then pass out again without dragging or carrying with them, or
damaging, the threads, which are laid or reeled crosswise or transversely over one
another.
After the brushes have passed out of the hank, the latter is unstretched by a
parallel movement of one of the yarn-carrying rollers, is moved forward by a rotary
movement of the same roller, and is again tightened and stretched by another
parallel movement of one roller, after which the brushes are again caused to enter
the bank.
A machine according to my invention is as follows:-
One of the yarn-rollers (hereinafter referred to as the stationary yarn-roller) is
mounted on the machine-framing and the other is mounted at the upper part of a
lever that is pivoted in the lower part of the machine. This lever is operated by means
of a cam which is fixed on a transverse shaft in the upper part of the machine
(hereinafter referred to as the cam-shaft) and which acts upon a roller carried by
the lever. The yarn-roller mounted on the lever is rotated by means of a pawl in
consequence of the movement of the lever as hereinafter described.
Two brushes are mounted (in such a manner that oue of them will be inside and
the other outside a bank placed on the aforesaid yarn-rollers) each in one of two
arms that receive from two eccentrics fixed on the cam shaft, a rocking-motion
about & pin, arranged at the end of the horizontal member of a bent lever which is
operated by a second cam on the cam-shaft so as to raise and lower the said pin, the
result being that each of the brushes describes an ellipse the shape of which is
determined by the last-mentioned cam.
The two eccentrics and the secondly mentioned cam are so adjusted as to causo the
brushes to describe the lower halves of their ellipses and to engage in the hank while
and as long as the latter is tight, whilst the brushes describe the upper halves of their
ellipses while the bank is slack and is being moved on and stretched.
The depression of a treadle connected with the yarn-roller lever causes that lever
to move away from the cam-shaft, and thus to move the corresponding yarn-roller
nearer to the stationary yarn-roller and also at the same time, (by raising the above-
Imentioned horizontal lever-arin, against whose under-side hears a roller operated by
the treadle) to move the brushes into their highest position, so as to allow of the easy
and convenient removal of the brushed and stretched hank from the yarn-rollers, and
of the placing of a fresh hank into position.

page_text: When the treadle is released, the yarn-roller lever and the treadle are returned, by
ineans of a counter-weight, into their initial positions, and the brushes move back
into their lower position.
The mode of working the machine is as follows:-
The driving is effected by means of the shaft that carries, as above stated, the two
cams and the two eccentrics. The yarn-roller levor with its roller is moved nearer
to the stationary-yarn-roller by means of the treadle, and the brushes are at the
same time raised to their highest positions by means of the roller operated by the
treadle, whereupon a hank is placed around the yarn-rollers. The treadle is now
liberated and as a result the bank is tightened and stretched and the brushes, being
no longer held up by the roller just mentioned, enter the threads of the hank.
When through the rotation of the cain-shaft, the can first herein before mentioned
again reaches the corresponding roller on the cam-roller lever, the brushes move
away from the bank. The pawl aforesaid rotates the yarn-roller ou the lever and
thereby moves the bank forwards to a corresponding extent, whereupon the hank is
again tightened and stretched. The series of operations is then repeated until the
hank of yarn has been sufficiently brushed and stretched.

Improvements in Machines for Finishing Yarn in the Form of
Hanks or Skeins.
1, AUGUST MONFORTS, of Munchen-Gladbach, Germany, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be performed
to be particularly described aud ascertained in and by the following statement:-
This invention relates to a machine for brushing and stretching yarn in the form
of hanks or skeins, in which flat brushes are employed whose bristles pass between
the threads from outside and inside the bank or skein (hereinafter referred to as a
hank) whilst the latter is at rest, and brush the same for a long or short distance as
required, and then pass out again without dragging or carrying with them or
damaging threads which are laid crosswise or transversely over one another.
After the brushes have passed out of the hank, the latter is unstretched by a
parallel movement of one of the yarn-carrying rollers, is moved forward by a rotary
movement of the same roller, and is again tightened and stretched by another
parallel novement of one of the rollers, after which the brushes are again caused to
enter the hank.
Figs. 1 and 2 of the accompanying drawings are respectively a side elevation and a
plan showing a machine constructed according to my invention.
g is a yarn-roller (hereinafter referred to as the stationary yarn-roller) mounted on
the machine-framing and g is another yarn roller mounted on a pin at the upper
end of a lever h¹ pivoted in the lower part of the machine at c. This lever his
operated by means of a cam d' which is fixed on a transverse shaft w (hereinafter
referred to as the cam-shaft) and which acts upon a roller r carried by the lever.
The yarn-roller g mounted on the lever h' is rotated by means of a pawl k² in
consequence of the movement of the lever h' as hereinafter described. 6¹³ are two
brushes arranged in such a manner that one of them will be inside and the other
outside a hank placed on the yarn-rollers g¹ g². These brushes are mounted on

page_text: arms a' a' that receive from two eccentrics el e fixed on the cam shaft wa rocking
motion about a pinz arranged at the free end of the horizontal arm
of a bent
lever h³ which is operated at the required times by a second cam on the cam
shaft w so as to raise and lower the said pinz the result being that each of the
brushes 6 6 will describe an ellipse the shape of which is determined by the form of
the cam e³.
The two eccentrics e' e and the cam are so adjusted as to cause the brushes b¹ b²
to describe the lower halves of their ellipses and to take into the hank while and as
long as the latter is tight, whilst the brushes describe the upper halves of their
ellipses while the bank is slack and is being moved onward and re-stretched.
'The depression of a treadle t connected with the lever h' causes that lever to move
away from the cam-shaft w, and thus to move the corresponding yarn-roller gt nearer
to the stationary yarn-roller g' and also at the same time, (by raising the horizontal
lever-arm h, against whose under-side bears a roller on the treadle t) to move the
brushes into their highest position, so as to allow of the easy and convenient
removal of the brushed and stretched hank from the yarn-rollers gl g, and of the
placing of a fresh hank into position.
When the treadle t is released, the lever h' and the treadle are returned by means
of a counter-weight G into their initial positions, and the brushes move back into
their lower position.
The mode of working of the machine is as follows:-
The driving is effected by means of the shaft w provided with the cams d¹ and e³
and the eccentrics ele. The lever with the roller g is moved nearer to the
roller g by means of the treadle t and the brushes b b are at the same time raised
to their highest positions by means of the roller whereupon a hank is placed
around the yarn-rollers, gg. The treadle t is now liberated and as a result the
hank is tightened and stretched and the brushes 6 b being no longer held up by
the roller enter the threads of the hank in which they are caused to travel by the
action of the eccentrics el e and came, and so brush the bank.
When, through the rotation of the cam-shaft w, the cam d' again reaches the
roller the brushes 616 are moved away from the hank and the pawl k² rotates
the yarn-roller g and thereby moves the hank forwards to a corresponding extent,
whereupon the hank is again tightened and stretched. The series of operations is
then repeated until the bank of yarn has been sufficiently brushed and stretched.
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 machine for brushing and stretching yarn in the hank, in which the hank of
yarn is arranged over two rollers, and when in a stretched condition and at rest is
brushed simultaneously from the outside and the inside, after which the brushes are
withdrawn, the bank is unstretched by a parallel movement of one of its supporting
rollers, and is moved forward by rotary movement imparted to the said roller so that
fresh portions of it will be brought into position to be brushed and is then again
stretched by another parallel movement of one roller, anbstantially as described.
2. In a machine of the kind referred to in Claim 1 for brushing and stretching
yarn in the bank effecting the to-and-fro motion of the brushes b and from the
driving shaft w by means of two eccentrics e and e and the up and down motion of
the said brushes by means of an eccentric e³ which is also mounted on the shaft w,
and which acts upon a lever h² on which is mounted the pinz to which are pivoted the
arms a' a that carry the brushes, substantially as described.
3. In a machine of the kind referred to in Claim 1 for brushing and stretching yarn
in the hank, effecting the rotary movement of the roller g* which is mounted in the
lever by means of a ratchet wheel on the roller g³, and a pawl the said pawl
during the parallel movement of the roller g' that unstretches the hank, causing the
ratchet to rotate and thereby rotate the roller g³ the movement of the lever
in

page_text: relation to the pawl being effected either by a cam mounted on the shaft w, or by
means of a trendle, the arrangement in the latter case being such that the brushes b¹
and b will be raised by the roller to their highest position, substantially as
described.
4. Machinery for brushing and stretching yarn in the hank, substantially as shewn
in and described and with reference to the drawings.
