Improved Machine for Sizing and Dressing Hank Yarn.
BERNHARD COHNEN, Grevenbroich, Germany, Manufacturer and Machine Maker,
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:-
On an axle a two stars b b are keyed, on which are attached six other axles by
means of pedestals. (Fig. 1 & 2.)
These axles carry the rollers c, c₂ C, C₁ C, Co. In connection with each roller is
another roller f, which is fastened on the arms J, J2 J3 J. J. Je The rollers f can
be moved from and to the rollers c. (Fig. 1 & 2.)
The hanks are laid on the pairs of rollers c, f2, Cz fa, C₁ f₁, Cz fs, c. f, and now the
springs h stretch the hanks so, that the turning rollers c set the hanks also in motion
and now the chain d drives ca fa, ca f₁, c₁ f₁, c, fs, cofe, but the chain is conducted so,
that the c, f, is not turned. (Fig. 1.)
The yarn is changed on the roller pair c, f₁, to do this the roller f, is lifted
towards the roller c, and if the roller c, would be turned the loosened yarn would
be destroyed because, it would run round the rollers c,. During the time the
workman is changing the yarn on the pair of the hanks on ca fa, c. f, are running
through the size while the superfluous size is pressed out by the pressing roller r,
on the roller pair c. f. (Fig. 1.)
During the same time the yarn is loosened on c, f, and c. f. by brushes or other
means. (Fig. 1.)
During the time the yarn is changed the whole system stands still only the roller-
pairs with the yarn on them except the pair c, fi, are turned the yarn on the roller
pairs c, f, and c, fa is sized and the pressing out and loosening apparatuses work.
(Fig. 1).
When the yarn is changed and the roller pair c₁ f, is set in order, the whole
system is turned so that the pair c, f, occupies the
ff, that of c. f. c. f. that of cf cf, that ofthe place of of, c. f, that of
c. f. (Fig. 1.)
pair c, f, occupies the place of c, f, with the sized and loosened yarn on it.
Immediately this roller pair is not turned so, that the yarn can be changed, while
f now c₂ f, is set in motion. (Fig. 1.)
The
The whole system is kept on its place by a bolt e Fig. 2 the chain is turning the
five roller pairs. The power to turn the five roller pairs in action round is greater
than that one to turn the system. The chain is constantly in motion.
he bolt, e, is loosened from the star b the roller pairs stop and immediately the
As soon as
chain begins to turn round the system for another pair of rollers that is the sixth
part of the circumference. The bolt stops the system by itself on the right
lace (f).
Having now particularly described and ascertained L

page_text: Invention, and in what manner the same is to be performed, I declare that what
I claim is:
A hank sizing machine which has a certain number of roller pairs corresponding
with the operations of sizing, pressing out and brushing the hank yarn.
The machine so constructed, that while the whole system is stopped, the roller
pairs for sizing, pressing out and loosening the yarn are in action while the pair, on
which the yarn is changed, is not in motion.
After moving the whole system forward the roller pair with the fresh yarn comes
into the size and is set in motion immediately. The roller pair which was in the
size comes to the pressing out roller, that one which was on this roller reaches the
loosening apparatuses while the roller pair which was on the loosening apparatuses
is set out of motion and brought to the place where the yarn is changed.
