Improvements in Machines or Apparatus for Winding Yarns
and Threads.
1, HEINRICH DEUTSCH, of Kolingasse 6, Vienna, IX, Austria, Merchant, do
hereby declare the nature of this invention to be as follows :—
The object of this invention is to enable machines for winding yarn and threads
upon cards or reels to give a considerably increased output and to work almost
continuously. This object is attained by so constructing and arranging the
machines that during the winding of one row of cards or reels, another row of
cards or reels can be placed in position and that after the winding has been completed
the empty cards or reels can be brought into the working position by the same act
as that for removing the full cards or reels therefrom; winding-machines according
to this invention are also so constructed as to be adapted for quick and accurate
winding and to ensure the winding upon the cards or reels of a definite length of
thread, which can be varied according to requirements.
In the accompanying drawing,
Fig. 1 is a longitudinal section,
Fig. 2 a front elevation, partly in section on the line II-II, Fig. 1,
Fig. 3 a cross-section on the line 111-III and 3-3. Fig. 1,
Fig. 4 a cross-section on the line IV-IV, Fig. 1, and
Fig. 5 a sectional plan of a winding-machine constructed according to this
invention.
The driving-shaft A. of the machine is provided with a loose belt-pulley E and is
adapted to be rotated thereby through a friction-cone B which can be thrown into
gear by means of a lever C and is connected to the shaft A by a feather D. On
the shaft A there are secured a number of skew-wheels F the teeth of which are
cut at 45 to the axes of the wheels and gear into similar skew-wheels G secured on
the spindles H which are arranged horizontally and at right angles to the shaft A.
These spindles are bored longitudinally and carry on their front ends flyers I
provided with eyes 1 and 2 through which the thread is drawn.
The rotary motion of the driving-shaft A is also transmitted by means of spur-
wheels K and K to a shaft L, on which is a worm M that engages with a worm-
wheel N keyed on the cross-shaft L', and thus serves to rotate a cam O mounted
on the shaft L¹.
Against the cam O bears a roller R mounted on a cross-head S to which are
fastened two connecting-rods P and P' which are guided in a rectilinear manner in
the side pieces Q and Q1 of the framing. Cords U, guided over pulleys V, are
attached to the crosshead S at W, and carry weights T. As the cam O rotates,
the roller R being in contact therewith, is caused to move the connecting-rods P
and P backwards. As soon as the cam ceases to push the roller P backwards, the
weights Tserve to pull the connecting-rods P and P' forwards again.
If a grooved cam be employed instead of a face-cam it is clear that the parts T,
U and V can be omitted, because the roller R will then be constantly guided in a
constrained manner, by the cam itself and will serve to move the connecting-rods
both backwards and forwards. The connecting-rods P and P' are provided at
their front ends with a circular groove X¹ and a tooth X (Fig. 5) which fit
respectively on and in a tooth z and a groove 21 (Fig. 2) of discs a and a¹, which
are let into the side pieces Q and Q₁of the framing in such a manner as to be
capable of rotating therein. The discs a and a' can be rotated by means of a shaft g
2

page_text: which is actuated by means of a crank-handle è in which is mounted a spring-
controlled pin b that, by entering recesses in the side wall of the piece Q', serves to
lock the crank in corresponding positions. The discs a and a' are formed on their
adjacent sides with a wide grooved in which movable transverse pieces e and e
accurately fit. The pieces e and e' are formed at their ends with a circular
groove and a tooth which are respectively adapted to engage with the tooth z
and the groove 2 of the discs a and a¹. To the transverse pieces e and e¹ there are
screwed clamping-jaws h and ' between which are inserted the cards on which the
yarn or thread is to be wound.
When the yarn or thread is to be wound on reels,
the clamping-jaws and are replaced by spring-pins upon which the reels are
mounted.
The device for enabling only an exactly definite length of thread to be wound on
each card, comprises an inclined shaft which engages at one end by means of a
worm-wheel k with the worm M, and has loosely mounted on it at its other end a
pointer which is provided with handle m, and is pressed by means of a spring
towards or against a graduated disc n that also forms a bearing for the shaft i, so
that when the latter is rotated, the pointer is carried along with it and thus
indicates on a scale provided on the disc n the exact length of thread for oue
winding.
Before the machine is started, the handle m is rotated so as to bring the pointer /
over the zero-point of the scale. The threads to be wound are drawn through the
bores of their respective spindles H and through the eyes 1 and 2 of the corre-
sponding flyers I and then clamped fast between the jaws or in the pins
corresponding thereto according as the thread is to be wound upon cards or reels.
Similarly the transverse pieces e and e' are brought by means of the crank c into
the position shown in the drawings, and the friction-cone B is then thrown into
gear.
The driving-shaft A thus rotated causes the rotation of the skew-wheels F and G
and through these that of the spindles H, whereby the threads drawn through the
latter are wound upon the cards inserted between the clamping jaws / or upou the
reels placed on the corresponding pins. Since the motion of the shaft A also serves
to rotate the cam O, then, as soon as the eccentric acts upon the roller R, the
connecting-rods P and P¹ are moved back in the direction of the arrow (Fig. 1)
and the transverse piece el is carried along by the same
on account of the
engagement of their teeth x in the grooves f of piece e¹. By this means the
transverse piece el is guided or moved rectilinearly in the groove d of the discs a
and a and in the guides of the side pieces Q and Q', and it carries back with it the
clamping jaws or the reel-pius as the case may be and thus causes the thread to
be wound spirally around the cards or reels for a length corresponding to the length
of stroke of the cam O. On further rotation of the cam O the weights T pull the
connecting rods P and P' and through these the transverse piece e¹ together with
the clamping-jaws h or the corresponding pins forwards in the direction opposite to
that of the arrow, the guide-roller R continuing to bear against the cam O.
This to and fro movement of the transverse piece e', and the consequent advancing
and receding winding-motion of the thread upon each card or reel, continues until
the machine is stopped by the disengagement of the cone B from the pulley C, which
is effected as soon as the pointer lindicates on the divided dise n the desired length
of thread to be wound.
During this winding-operation, empty cards are inserted into the clamping-jaws h
of the transverse piece e, or empty reels are placed upon the corresponding pins.
After stopping the machine, the handle c is turned through 180°, and then its
spring-pin snaps into another hole. In consequence of this the axle g which has
two diametrically opposite flat sides and with it the two discs a and a¹ and the two
transverse pieces e and e¹, are rotated, the latter being carried round by the axle g,
whilst the discs a and a¹ keep the connecting-rods P and P' fixed in their position
by means of their teeth and grooves through the turn in the grooves Z¹
and on the teeth Z of these rods.

page_text: Thus by rotating the handle c the clamping-jaws with the inserted empty
cards or their equivalents, the pins with the empty reels placed thereon, are
brought into the proper position for winding, after which the pointer is turned
back into the zero-position and the machine is again set into operation.
During the winding of the cards or reels, the full cards or reels are removed
from the clamping-jaws or pins, and are replaced by empty ones, so that after the
completion of the winding-operation the clamping-jaws h or the corresponding pins
can be brought at once into the proper position for winding by merely turning the
handle c through 180°.

Improvements in Machines or Apparatus for Winding Yarns and
Threads.
1, HEINRICH DEUTSCH, of Kolingasse 6, Vienna IX, Austria, Merchant, 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 object of this invention is to enable machines for winding yarns and threads
upon cards or reels to give a considerably increased output and to work almost
continnously. This object is attained by so constructing and arranging the machines
that during the winding of one set of cards or reels another set of cards or reels can
be placed in position and that after the winding has been completed the empty
cards or reels can be brought into the working position by the same act as that for
removing the full cards or reels therefrom. Winding-machines according to this
invention are also so constructed as to be adapted for quick and accurate winding
and as to ensure the winding upon the cards or reels of a definite length of thread,
which can be varied according to requirements.
In the drawings filed with my Provisional Specification,
Fig. 1 is a longitudinal section,
Fig. 2 a front end elevation, partly in section on the line II-II of Fig. 1.
Fig. 3 a cross section partly on the lines III-III and partly on the line 3-3
of Fig. 1.
Fig. 4 a cross section on the line IV-IV of Fig. 1 and
Fig. 5 a sectional plan of a winding machine constructed according to this
invention.
The driving-shaft A of the machine is provided with a loose belt-pulley E and is
adapted to be rotated thereby through a friction-cone B, which can be thrown into
gear by means of a lever C and is connected to the shaft A by a feather D. On
the shaft A, there are secured a number of skew or helical wheels F the teeth of
which are cut at 45° to the axes of the wheels and gear into similar skew or helical
wheels G secured on the spindles H, which are arranged horizontally and at right
angles to the shaft A. The spindles H are bored longitudinally and carry on
their front ends, flyers I provided with eyes 1 and 2 through which the thread is
drawn.
The rotary motion of the driving-shaft A is also transmitted by means of spur-
wheels K and K' to a shaft L, on which is a worm M, that engages with a worm-
wheel N keyed on a cross-shaft L' and thus serves to rotate a cam O secured on
the shaft L.
Against the cam O bears a roller R mounted on a cross head S to which are
fastened two connecting rods P and P¹, which are guided in a rectilinear manner in '

page_text: side pieces Q and Q₁ of the framing. Cords U, guided over pulleys V, are attached
to the crosshead S at W and carry weights T. As the cam O rotates, the roller R,
being in contact therewith, is caused to move the connecting-rods P and P
backwards against the action of the weights T, which, as soon as the cam ceases to
push the roller R backwards, serve to pull the connecting-rods P and P¹ forwards
again. If a grooved cam be employed instead of the face-cam O, it will be obvious
that the parts T, U and V can be omitted, because the roller R will then be
constantly guided in a constrained manner by the cam itself and will serve to move
the connecting-rods both backwards and forwards.
The connecting-rods P and P₁ are provided at their front ends each with a
circular groover and a tooth x (Fig. 5) which are adapted to fit respectively on
and in a circular tooth or projection 2 and a groove z¹ (Fig. 2) formed on and in the
corresponding disc a or a¹ these discs being let into the side pieces Q and Q' of the
framing in such a manner as to be capable of rotating therein. The discs a and a¹
can be rotated by means of a shaft g, which is actuated by means of a crank-
handle c and is provided with a spring controlled pin b, which by entering one or
other of two diametrically arranged recesses in the side wall of the piece Q', serves
to lock the crank-handle c in corresponding positions. The discs a and a¹ are each
formed on its inner side with a wide groove d in which movable transverse
pieces e and e¹ accurately fit. The pieces e and e' are formed at their ends with
circular grooves and teeth f1 (Fig. 5) which correspond respectively to the
grooves and the teeth z of the discs a and a¹ and are respectively adapted to
engage with the teeth and the grooves al of the connecting-rods P and P.
To the transverse pieces e and there are screwed clamping-jaws h and h¹
respectively between which are inserted the cards on which the yarn or thread
is to be wound. When the yarn or thread is to be wound upon reels, the
clamping-jaws h and are replaced by spring-pins upon which the reels are
mounted.
The device for euabling only an exactly definite length of thread to be wound on
each card, comprises an inclined shaft which engages at one end by means of a
worm wheel with the worm M, and has loosely mounted on it at its other end a
pointer which is provided with a handle m and is pressed, by means of a spring,
towards a graduated disc n (which forms a bearing for the shaft i) and against a
conical portion of the said shaft, so that when the shaft i is rotated, the pointer / is
carried along with it by means of friction, and thus indicates on a scale provided on
the disc n the exact length of thread wound upon each card or reel.
Before the machine is started, the handle m is rotated so as to bring the pointer /
over the zero-point of the scale. The threads to be wound are drawn through the
bores of their respective spindles H and through the eyes 1 and 2 of the corre-
sponding flyers I and are then clamped fast between the jaws or on the pins
corresponding thereto, according as the thread is to be wound upon cards or reels.
Likewise, the transverse pieces e and e' are brought by means of the crank handle c
into the positions shown in the drawings, and the friction-cone B is then thrown
into gear with the driving pulley E.
The driving-shaft A thus rotated, causes the rotation of the helical wheels F
and G and through them that of the spindles H, whereby the threads drawn
through the latter are wound upon the cards inserted between the clamping-jaws
or upon the reels placed on the corresponding pins. Since the motion of the
shaft A also serves to rotate the cam O, then, as soon as the said cam acts upon
the roller R, the connecting-rods P and P¹ are moved back in the direction of the
arrow (Fig. 1), and the transverse piece e¹ is carried along by the same on account
of the engagement of the teeth of the rods P and P¹ in the grooves f of the
piece e. By this means the transverse piece e¹ is guided or moved rectilinearly in
the grooves d of the discs a and a' and in the guides of the side pieces Q and Q,
carrying back with it the clamping-jaws h or the reel-pins, as the case may be, and
thus causing the thread to be wound spirally around the cards or reels for a length
corresponding to the length of stroke of the cam O. On further rotation of the

page_text: cam O the weights T pull the connecting-rods P and P' and, through them, the
transverse piece e', together with the clamping-jaws h, or the corresponding pins,
forwards in the direction opposite to that of the arrow, the guide-roller R continuing
in contact with the cam O.
This to and fro movement of the transverse piece e¹, and the consequent advancing
and receding winding motion of the thread upon each card or reel, continues until
the machine is stopped by the disengagment of the cone B from the pulley C, which
is effected as soon as the pointer indicates on the divided disc n that the desired
length of thread has been wound.
During this winding-operation, empty cards are inserted into the clamping-jaws h
of the transverse piece e, or empty reels placed upon the corresponding pins.
After stopping the machine, the handle c is turned through 1810, and then its
spring-pin snaps into the oppositely arranged recess in the piece Q. In
consequence of this, the axle which has two diametrically opposite flat sides, and
with it the two discs a and a¹ and the two transverse pieces e and e', is rotated, the
pieces e and e¹ being carried round by the axle g and the discs a and a¹ keeping the
connecting-rods P and P' fixed in position by means of their teeth fi and grooves f,
which turn in the grooves and on the teeth of the said rods. Thus by rotating
the handle the clamping-jaws h, with the inserted empty cards or their
equivalents, the pins with the empty reels placed thereon, are brought into the
proper position for winding, after which the pointer is turned back into the zero-
position and the machine is again set into operation. During the winding of the
fresh set of cards or reels, the previously wound cards or reels are removed from
their clamping-jaws or pins, and are replaced by empty ones, so that after the
completion of the winding-operation then taking place, the clamping-jaws h, or the
corresponding pins, can be brought at once into the proper position for winding
the fresh set of cards or reels by merely turning the handle c through 180°.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed 1 declare that what
I claim is :-
:-
1. In a machine for winding yarns or thread on cards or reels, an axle g and
discs a and a', which are adapted to engage with the connecting-rods
and P¹ and
can be rotated in the latter, in combination with transverse pieces e and e¹, which
are capable of being moved in the said discs and, when the axle g is rotated, of
being rotated therewith, the said transverse pieces carrying two sets of clamping-
jaws h and h' for the insertion of the cards to be wound, or two sets of spring-pins
for the reception of reels, and being arranged to be brought, by the rotation of the
axle g, alternately into engagement with the connecting-rods Paud P¹, so that
during the winding of the cards in one set of clamping-jaws or the reels on one set
of spring-pins, empty cards can be inserted in the other set of clamping-jaws or
empty reels placed upon the other set of spring-pins, and, after the winding-
operation is completed, can be brought into the working-position by turning the
axle g, substantially as herein before described.
2. For the purpose, in a machine for winding yarns or threads upon cards or
reels, of exactly fixing the length of yarn or thread to be wound on in each case or
of indicating the length of yarn or thread wound, of a graduated disc n and a
pointer arranged to work over the same and loosely mounted on a shaft i so as to
be driven by frictional contact therewith, substantially as hereinbefore described.
3. My improved machine or apparatus for winding yarns or threads on cards or
reels, substantially as described and shown.
