PROVISIONAL SPECIFICATION.
Improvements in Clearing-apparatus, suitable for Yarn-winding
and similar Machines.
I, LOUIS DRACH, of Bühl, near Gebweiler, Alsace, Germany, Works-manager,
do hereby declare the nature of this invention to be as follows:-
For the purpose of removing, during winding, any impurities such for example
as husks, particles of straw, and knots that may occur in the yarns or threads to be
wound, it has hitherto been usual to pass the latter through or over thin velveteen,
or brushes. But these devices have the drawback that they do not sufficiently
clear the yarn or thread, and that they also remove therefrom good fibres, which
they accumulate so that the fluff thereby formed is carried away by a slight
increase in diameter of the yarn or thread, or by a small knot, and is carried on to
the bobbin. A further drawback attending their use is that the tension of the
yarn or thread cannot be satisfactorily regulated by these means.
Now the object of this invention is to obviate these disadvantages.
Fig. 1 of the accompanying drawings represents in cross-section part of a yarn-
winding machine provided with an arrangement of clearing-apparatus according to
this invention;
Fig. 2 shows in plan a portion of the arrangement represented in Fig. 1;
Fig. 3 is a cross section on the line of Fig. 2;
Figs. 4 and 5 are plans of modified forms of clearers; and
Fig. 6 represents a further modification.
From the cops
(Fig. 1), or from the reels on which the yarn to be wound is
situated, the threads pass through eyes C and over a bar D before reaching the
clearing-apparatus.
This apparatus comprises a number of clearers each consisting of two toothed
bars or cheeks G and H, whose sets of teeth engage to any desired depth with each
other and between which the yarn is passed through in a zig-zag path. The
toothed cheeks are placed nearer to or further from each other according to the
number, quality, and tension of the yarn. The cheek G may be cast in one piece
with the extension A, which serves for attachment to the winding-machine; whilst
the other cheek H may be adjustably connected to the cheek G or the extension A
by means of a hinge and screw-bolts or the like.
For the purpose of guiding the yarn between the teeth of the cheeks G and H,
the front and rear teeth are each provided with a heel F as shown in cross section
in Fig. 3.
N is a plate, semi-circular in outline in its upper part (see Figs. 1, 2 and 3) that
is secured, by screws or other suitable means, between each pair of clearers for the
purpose of facilitating the insertion of the thread into the toothed portions of the
corresponding clearers.
Each thread is passed through a clearer, and therefore there are as many such
clearers, which are bolted to an angle-bar E (Fig. 1), as there are to be threads on
one side of the winding-machine. The bar E is capable of being rotated by means
of an arm M, which bears upon a bar i carried by the thread-guiding board K.
To the thread-guiding board there is bolted a sheet-metal bar K' through whose
incisions the threads pass to the bobbins. As the thread-guiding board is raised
and lowered for the purpose of distributing the convolutions of the yarn over the

page_text: length of the bobbins upon which it is to be wound, the clearers are, by means of
the lever M, also raised and lowered at the same time therewith, so that the exit-
angle of the threads, and consequently their tension, remains the same.
The teeth of the cheeks G and H may be of metal or other hard material.
They may be of trapezium-shape as shown in Fig. 4 or in the form of rectangular
plates inserted in the cheeks as shown in Fig. 5: and there may be any desired
number of them arranged one behind another. Moreover each tooth may have a
small central recess as shown in Fig. 6, for guiding the yarn.
As the yarn moves past the sharp edges of the teeth, the impurities, such as
husks, particles of straw, and loose fibres, are scraped out, knots are removed, and
weak parts of the yarn are broken, so that in the subsequent warping and dressing
operations the yarn will not break so frequently. Furthermore, the tension of the
yarn can be accurately regulated by adjusting the engagement of the teeth. The
frequent cleaning necessary in the case of clearing-apparatus as hitherto
employed is obviated by my invention. Moreover, the wear and tear of the
apparatus hereinbefore described, and consequently the expense of keeping the
same in working order, is extremely small as compared with that of velveteen,
plush, or brushes.

Improvements in Clearing apparatus, suitable for Yarn-winding
and similar Machines.
I, LOUIS DRACH, of Bühl, near Gebweiler, Alsace, Germany, Works-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:-
For the purpose of removing, during winding, any impurities such for example,
as busks, particles of straw, and knots that may occur in the yarns or threads
to be wound, it has hitherto been usual to pass the latter through or over thin
velveteen, or brushes. But these devices have the drawback that they do not
sufficiently clear the yarn or thread, and that they also remove therefrom good fibres,
which they accumulate so that the fluff thereby formed is carried away by a slight
increase in diameter of the yarn or thread, or by a small knot, and is carried on to
the bobbin. A further drawback attending their use is that the tension of the
yarn or thread cannot be satisfactorily regulated by these means.
Now the object of this invention is to obviate these disadvantages.
Referring to the drawings filed with my Provisional Specification,
Fig. 1 represents in cross-section, part of a yarn-winding machine provided with
an arrangement of clearing-apparatus according to tbis invention;
Fig. 2 shows in plan a portion of the arrangement represented in Fig. 1;
Fig. 3 is a cross section on the line of Fig. 2;
Figs. 4 and 5 are plans of modified forms of clearers; and
Fig. 6 represents a further modification.
From the cops B (Fig. 1), or from the reels on which the yarn to be wound is
situated, the threads pass through eyes C and over a bar D before reaching the
clearing-apparatus.
This apparatus comprises a number of clearers each consisting of two toothed
bars or cheeks G and H, whose sets of teeth engage to any desired depth with each
other and between which the yarn is passed through in a zig-zag path. The
toothed cheeks are placed nearer to or further from each other according to the

page_text: number, quality and tension of the yarn. The cheek G may be cast in one piece
with the extension A, which serves for attachment to the winding-machine; whilst
the other cheek H may be adjustably connected to the cheek G or the extension A
by means of a hinge and screw-bolts or the like.
For the purpose of guiding the yarn between the teeth of the cheeks G and H,
the front and rear teeth are each provided with a heel F as shown in cross section
in Fig. 3. N is a plate semi-circular in outline in its upper part (see Figs. 1, 2,
and 3), that is secured, by screws or other suitable means, between each pair of
clearers for the purpose of facilitating the insertion of the thread into the toothed
portions of the corresponding clearers.
Each thread is passed through a clearer, and therefore there are as many such
clearers, which are bolted to an angle-bar E (Fig. 1), as there are to be threads on
one side of the winding-machine. The bar E is capable of being rotated by means
of an arm M, which bears upon a bar i carried by the thread-guiding board K.
To the thread-guiding board there is bolted a sheet-metal bar K¹ through whose
incisions the threads pass to the bobbins. As the thread-guiding board is raised
and lowered for the purpose of distributing the convolutions of the yarn over the
length of the bobbins upon which it is to be wound, the clearers are, by means of
the lever M, also raised and lowered at the same time therewith, so that the exit-
angle of the threads, and consequently their tension, remains the same.
The teeth of the cheeks G and H may be of metal or other hard material.
They may be of trapezium-shape as shown in Fig. 4 or in the form of rectangular
plates inserted in the cheeks as shown in Fig. 5; and there may be any desired
number of them arranged one behind another. Moreover, each tooth may have a
small central recess as shown in Fig. 6, for guiding the yarn.
As the yarn moves past the sharp edges of the teeth, the impurities, such as
husks, particles of straw, and loose fibres, are scraped out, knots are removed, and
weak parts of the yarn are broken, so that in the subsequent warping and dressing
operations the yarn will not break so frequently. Furthermore, the tension of the
yarn can be accurately regulated by adjusting the engagement of the teeth. The
frequent cleaning necessary in the case of clearing-apparatus as hitherto employed
is obviated by my invention. Moreover, the wear and tear of the apparatus
hereinbefore described, and consequently the expense of keeping the same in
working order, is extremely small as compared with that of velveteen, plush, or
brushes.
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. For cleaning yarns or threads in yarn winding and similar machines, clearing-
apparatus comprising stationary toothed bars or cheeks (G H), whose teeth engage
with one another adjustably in such a manner that the yarn or thread which is
passed between them in a zig-zag direction, will not only be freed from impurities,
but will also be subjected to the desired tension, substantially as herein described.
2. Clearing apparatus for use with yarn winding and similar machines, con-
structed, arranged and operating as hereinbefore described with reference to and
shown in the drawing herein referred to.
