page_text: We, JEAN CHARLES SPACH and FRÉDÉRIC ALBERT SPACH, of Rothau, Alsace,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct a machine for enabling any kind of
thread to be wound either on cards, plates or tubes in spirals of smaller. or greater
length and which are in very exact juxtaposition. These two conditions are realised
in our system with threads of different thickness by means of a very easy adjust-
ment, whereas, hitherto, it has only been possible to obtain them with complicated
and costly machines, in which the adjustment is difficult. Our system has further
the advantage of allowing very great speed, inasmuch as only continuous rotary
movements are used; a product of very good appearance is, therefore, obtained
very economically.
The following is a description of the arrangement of the machine, which as above
stated, while being of very simple construction and only requiring very simple
adjustment, permits, 1st, of the variation of the length of the path of the thread,
that is to say, the length of the card, plate or tube covered by the same; 2nd, of the
regulation, with great precision, of the distance between the adjacent threads
according to the thickness of the thread to be wound.
The card, plate or tube which is to receive the thread is mounted on an inclined
shaft, having a rotary movement on its axis and also a movement round a fixed
central shaft, situated in the same plane as itself.
For this purpose the inclined shaft is rigidly connected to a sleeve, having a
counter-weight, which sleeve turns freely on the central shaft and is put in motion
by a pulley and a band, and the inclined shaft has a pinion keyed on its lower end,
that is the end opposite the card, plate or tube, which pinion gears with a toothed
wheel mounted on the central shaft. It will thus be seen that the rotary
movement will be transmitted to the inclined shaft carrying the card, plate
or tube.
On the side of the card, plate or tube, at the height of the point of intersection
of the two shafts is placed an eye through which the thread passes, and which can
be moved in a plane perpendicular to the fixed shaft with the object of adjustment,
as will be explained further on. This eye is mounted on the end of an arm,
pivoting round its other extremity.

page_text: The parts being thus arranged, if the movable shaft be put in motion, its two
movements of rotation combined will produce a winding, of which the length will
be determined by the projections of the point representing the eye on the movable
shaft in its two extreme inclinations.
In order to vary this length, it will be understood that it will suffice to move
the eye laterally as above stated, the length of winding becoming greater as the
eye is moved farther away and vice versa.
On the other hand, the space covered will have more or less spirals and these
will be consequently closer together or farther apart from one another according to
the number of teeth of the two gear wheels, for the. number of spirals produced
during the path will be equal to the number of revolutions which the movable
shaft will make on its axis, during the time that it makes one revolution round the
fixed shaft; there will be two spirals if it makes two revolutions, three spirals if it
makes three revolutions, and so on.
.If the relation of numbers is not represented exactly by an entire number, the
difference will produce the advance of the thread, and each thread will be so much
more apart from the next one as this difference is greater.
It is therefore necessary to be able to vary this difference at will, according to
the thickness of the thread, so as to be able to always obtain an exact juxta-
position.
We obtain this result with presicion and with great facility by giving a very
slow movement of rotation to the central gear wheel, which we have supposed up
to the present to be fixed, and with this object it is supplied with a worm wheel
driven by an endless screw.
It is preferable that the numbers of teeth of the two gear wheels should be prime
numbers, so that the same teeth of the pinion do not always gear with the same
teeth of the wheel, thus diminishing the wear. This will also produce the advance
of the thread, as will be understood, but in invariable quantity for a pair of given
wheels, and this will not, therefore, permit of regulating the machine for all
thicknesses of thread. We may, however, only employ this means in cases where
it will be sufficient.
All the moving parts are enclosed in a casing.

We, JEAN CHARLES SPACH and FREDERIC ALBERT SPACH, of Rothau, Alsace,
Manufacturers, 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 construct a machine for enabling any kind of
thread to be wound either on cards, plates or tubes in spirals of smaller or greater
length and which are in very exact juxtaposition. These two conditions are
realized in our system with threads of different thickness, by means of a very easy
adjustment, whereas hitherto it has only been possible to obtain them with
complicated and costly machines in which the adjustment is difficult. Our system
has further the advantage of allowing very great speed, inasmuch as only con-
tinuous rotary movements are used; a product of very good appearance is therefore
obtained very economically.
Fig. 1 of the drawings annexed to this specification, represents a vertical section
of our machine.
Fig. 2 is a plan view of same.
The following is a description of the arrangement of the machine, which as above
stated, while being of very simple construction and only requiring very simple
adjustinent, permits, 1st, of the variation of the length of the path of the thread,
that is to say, the length of the card, plate or tube covered by same; 2nd, of the
regulation with great precision, of the distance between the adjacent threads
according to the thickness of the thread to be wound.
The card, plate or tube A, which is to receive the thread is mounted on an
inclined shaft B, having a rotary movement on its axis and also round a fixed
central shaft C situated in the same plane as itself.
For this purpose the inclined shaft B is carried by a sleeve D having a counter-
weight E, which sleeve turns loosely on the central shaft, and is actuated by the
pulley F and a band, and the shaft B has a pinion G keyed on its lower end, that
is the end opposite the card, plate or tube, such pinion gearing with the toothed
wheel H mounted on the central shaft. It will thus be seen that the rotary
movement will be transmitted to the shaft B carrying the card, plate or tube.
On the side of the card, plate or tube, at the height of the point of intersection
of the two shafts, is arranged an eye or guide I, through which the thread passes,
and which can be moved in a plane perpendicular to the fixed shaft, with the
object of adjustment, as will be explained further on. This eye or guide is.
mounted on the end of an arm J, pivotting round its other extremity.
The parts being thus arranged, if the movable shaft be put in motion, its two
movements of rotation combined, will produce a winding of which the length will
be determined by the projections of the point representing the eye or guide upon
the movable shaft in its two extreme inclinations.
In order to vary this length, it will be understood that it will suffice to move
the eye or guide laterally as above stated, the length of winding becoming greater
as the eye is moved farther away and vice versa.
On the other hand, the space covered will have more or less spirals, and these
will be consequently closer together or farther apart from one another according to

page_text: the number of teeth of the two gear wheels G and H, for the number of spirals
produced during one path will be equal to the number of revolutions which the
movable shaft will make on its axis during the time that it makes one revolution
round the fixed shaft; there will be two spirals if it makes two revolutions, three
spirals if it makes three revolutions, and so on.
If the relation of numbers is not represented exactly by an entire number, the
difference will produce the advance of the thread, and each thread will be so much
more apart from the one next to which it is placed as this difference is greater. It
is, therefore, necessary to be able to vary this difference at will, according to the
diameter or thickness of the thread, so as to always obtain an exact juxtaposition.
We obtain this result with precision and with great facility by giving a very
slow movement of rotation to the central gear wheel, which we have supposed up
to the present to be fixed, and with this object it is provided with a worm wheel
driven by an endless screw.
It is preferable that the numbers of the teeth of the two gear wheels should be
prime numbers, so that the same teeth of the pinion do not always gear with the
same teeth of the wheel, thus diminishing the wear. This will also produce the
advance of the thread, as will be understood, but to an invariable extent for a
given pair of wheels, and this will, therefore, not permit of regulating the machine
for all thicknesses of thread. We may, however, only employ this means in cases
where it will be sufficient.
All the actuating mechanism is enclosed in a casing.
It will be readily understood that the details of construction of our machine may
be varied without departing from the nature of the invention.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The improved machine for winding any kind of thread on cards, plates, or
tubes, such machine being constructed and operating substantially as specified.
2. The improved machine for winding any kind of thread on cards, plates, or
tubes, consisting essentially in two shafts, of which one is inclined and is caused
to rotate round the other, while at the same time revolving on its own axis,
substantially as described.
3. In machines for winding any kind of thread on cards, plates, or tubes, the
means for actuating the inclined shaft B, consisting in a pulley F driven by a cord
or band and turning loosely on central shaft C, the shaft B being carried by such
pulley and provided with a pinion engaging a wheel on the central shaft C,
substantially as described and shown.
4. In machines for winding any kind of thread on cards, plates, or tubes,
imparting a slow rotary motion to the central gear wheel H, for the purpose of
producing a differential movement serving to regulate the spacing of the threads
on the cards, plates, or tubes, according to the diameters of such threads, sub-
stantially as specified.
5. In machines for winding any kind of thread on cards, plates, or tubes, the use
of a laterally adjustable thread guide serving to regulate the length of the card,
plate, or tube, to be covered by the thread, substantially as specified.
