Improvements in Yarn or Thread Winding Machines.
I, FERDINAND BOSSHARDT, of the firm of F. Bosshardt & Co. of 4, Corporation
Street, Manchester, in the County of Lancaster, Patent Agent, do hereby declare
the nature of this invention which has been communicated to me from abroad by
Julius Salzmann-Däniker, of St. Gallen, in the Republic of Switzerland, Mill-
owner, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to machines for winding bobbins, or cops, spools and the
like. The thread is laid by a winder on a rotating spindle, the bobbin whilst being
formed acts on a feeler mechanism in such a manner that when the desired thickness
of bobbin is attained a shaft having arms which carry the said spindle is connected
with and set in motion by a suitable driving arrangement. The said spindle with
the completed bobbin is thereby moved in a circle around the shaft carrying it as
well as moved forward by the feeler and the bobbin itself moved to the end of the
said spindle by a sliding collar employed thereon. After the said spindle has
again taken up its former position the winding of another bobbin commences.
With the feeler is also connected a knife which comes in action when the feeler is
forced back by the bobbin, in order to cut off the thread of the bobbin wound
previously but still remaining on the spindle which is then stripped off the spindle
by the one just wound.
On annexed drawing

Fig. 8 is a similar view with position of parts corresponding with Fig. 6.
On the base plate A° of the machine is screwed fast the casting A having
bearings for the shaft a which by means of two arms a¹, a¹, carries a second shaft b.
This shaft 6 carries the loose and fast strap pulleys R, R', respectively, and the
crank disc b with crank pin 2. Through the rod ³, pin 60 and lover 6' the
shaft (Figs. 1 & 2) and winder care set in operation by the crank dise b¹,
the spring serving to ensure a regular motion. The crank disc effects with
its periphery also the rotation of the pulley d' covered with leather, or a rubber
ring d and is pressed against the latter by means of a spiral spring a' attached to
the arm a'. The pulley is positioned on a short shaft (Figs. 3 & 6) the
continuation d of which forms the spindle for the winding of the bobbin and which
shaft is carried by the arms, d³, d³, formed on the boss fastened on the spindle e
(Figs. 4 & 6). The hollow spindle is mounted in the support A³ of the casting A
and carries a toothed wheel e', a portion of its teeth being removed as shown in
Fig. 2. The toothed wheel e and with it the shaft e is set in rotation by the
toothed wheel, on the shaft f which is actuated by means of the strap pulley f
independently of the motion given to the other parts of the machine. The spindle
is bored out, as shown in Fig. 4, and lined with brass bushes e for the reception of
a shaft g which carries the arm g¹ having a stripper g' placed on the spindle d. On
the spindle e are also placed two collars & h', (Figs. 4, 5 & 6) which are fastened
to the shaft g by means of pins 2, the latter pass through slots in the spindle e
(Fig. 5, and dotted in Fig. 4) so that the shaft g will revolve with the spindle, but

page_text: will also permit of being slid in the same. For this purpose is employed loosely
on the spindle e between the two collars & h', a sliding piece i which is prevented
from rotating by two pins ¹ gliding on the support A³ (Figs. 2 & 4) and which is
connected by means of the connecting rods i, 2, (Figs. 3, 5 & 6) and the levers i³, i³,
to a shaft, positioned crosswise to the spindle e. The displacement of the sliding
piece and that of the shaft is effected through the toothed wheel.e' which on
rotating oscillates through the crank rod and lever 1, 2, the shaft 20 with its
levers ³, 3.
Ordinarily, that is to say, during the winding of the bobbin, the described
revolution of the spindle e and displacement of the shaft g do not take place, but
the wheel runs in the gap.of the wheel el, as shown in Fig. 2, and leaves the
latter as well as the part which receives motion therefrom at rest. This position
of the wheel e¹ is determined by a feeler, the abutment k of which lays itself
against the bobbin o wound onto the spindle d, see Fig. 7, and is carried by
levers on the shaft l. The abutment k on the shaft is pressed against the
bobbin by the spring (Figs. 1, 2 & 7), the pin of the shaft / being positioned
in front of a stop on the wheel e' (Fig. 5), which stop e ensures the position of
the gap in the wheel e relative to the wheel f', as the crank disc b', under the
influence of the spring a², is pressed against the pulley das already described and
thereby has a tendency to turn the spindle e and the wheel e' in the direction of
the arrow (Figs. 2 & 7). Now if the abutment k is pushed back, see Fig. 7, owing
to the increased diameter of the bobbin the shaft with its pin is turned and
thereby the stop pine of the wheel e¹ liberated, which latter will give way to the
pressure of the disc which causes the teeth of the latter to come in gear with
those of the wheel f¹. On the lever k¹ is also arranged a knife pin such a manner
that the spindle d, see Figs. 3 & 7, is positioned between this knife and the abut-
ment . If the abutment is thus pressed back by the bobbin the knife p must also
move against the spindle d.
The working of the machine as far as described is as follows:-
The thread from the spool m through suitable eyes n, n, arrives at the winder c¹
and is wound into a bobbin by the spindle d. If the latter has received its proper
thickness, the wheel e¹ is brought into gear with the wheel f' owing to the abut-
ment k being pressed back and to the rotation of the shaft as specified (Fig. 7).
The wheel e with the spindle e then rotates and the spindle with the bobbin is
projected between the abutment k and knife and describes a circle (Fig. 8), whilst
the shaft g is advanced and the stripper g' pushes the bobbin on the spindle forward
into position shown in Figs. 4 & 6. After the completion of the described circle,
the pulley d returning forces the disc back into its former position and the
spindle passes again between the knife p and abutment k, which latter has advanced
and brought into the course of the stop pin e the pin, which causes the gap in
the teeth to be positioned underneath the wheel f¹ and thus effect the stoppage of
the wheel e. The winding of another bobbin may then be commenced, which
remains connected with the one previously wound and pushed forward; the thread
forming the connection is then cut by the knife p on the return movement of the
abutment k, each bobbin being stripped off the spindle by the one adjacent and
permitted to drop into a suitable receptacle.
For the purpose of stopping the machine automatically, in case the thread breaks,
the same is provided with a stopping motion as follows:-
On the shaft turns loosely the lever r carrying the strap fork r, which lever is
connected with the bar t guided at sand furnished with the knob t¹ a spring t²
drawing the strap fork and bar t to the left. On the stud which secures the
knob is arranged to rotate loosely the collar u formed with a nose u' in which is
fastened a pin u with guide eye u. When the machine is in motion the strap fork
is moved to the right by means of the knob t¹ and the bar with its projection to
hooked into s; should the thread break, the pin u², supported by the thread, falls,
see Figs. 1 & 7, and thereby brings the nose u' on the collar in the course of the
pin 6º, previously described in reference to the crank disc b', whereby the nose to
t

page_text: becomes disengaged, the bar t drawn to the left by the spring * and the strap
moved onto the loose pulley R.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
1st. A machine for winding bobbins, consisting of a mechanism for the winding
of thread on a rotating spindle in combination with a feeler arrangement and with
mechanism for moving the bobbin spindle from and to the feeler as well as
mechanism for the forward movement or stripping off of the bobbin (between the
movement of the bobbin spindle from and to the feeler) whereby the bobbin and
the feeler at given times are positioned apart from each other and in the meantime
the bobbin is displaced on and stripped off the epindle, after having been completed,
owing to the feeler being forced back relatively and the consequent disengagement
of the respective mechanism.
2nd. In an automatic bobbin winding. machine: The mechanism for the winding
of the bobbin consisting of a crank disc (1), wherefrom motion is derived for the
winder and of a pulley d. for the rotation of the bobbin spindle d, in which
mechanism the shaft of the disc b', pressed against the pulley d¹ by a spring, as
well as the shaft of the pulley d¹, are arranged to oscillate on the shaft and
spindle a&e respectively.
3rd. In an automatic bobbin winding machine: For the purpose of moving the
bobbin spindled from and to the feeler k, k, l, and stripping off the completed
bobbin, a wheel e¹ on the spindle e having a gap and rotated by means of the
toothed wheel in combination with the disengaging parts 1, 12, of the feeler k, k, l,
and with the pulley d' carried by the said spindle e and the disc 6' pressed against
the pulley d¹ by the spring a², for the purpose of retaining the toothed wheel e',
under ordinary conditions, by means of the fecler disengaging parts in such a
position that the gap in the wheel brings the driving wheel out of gear, whilst
on forcing back the feeler by the completed bobbin and thereby disengaging the
toothed wheel e¹, rotary motion is imparted to the latter from the disc band
the toothed wheel e' is brought in gear with the driving wheel fl.
4th. In an automatic bobbin winding machine: A knife (p) connected to the
feeler and forming the counter part of the feeler abutment k, which knife on
the feeler being forced back by the bobbin cuts in the meantime the bobbin
thread.
5th. In an automatic bobbin winding machine: The hollow spindle e carrying on
the one side, by means of the arms d, the pulley and on the other side the
toothed wheel e, in connection with the shaft having a stripper g³ and arranged
to be slid in the spindle e through its rotation (for instance by means of the wheel e¹,
rod, and lever,,, ) in order to effect, simultaneously with the oscillation of
the bobbin spindle d on the hollow spindle e, the displacement of the bobbin.
r
6th. In an automatic bobbin winding machine: The motion of selfactingly
stopping the machine when the thread breaks, consisting of a bar t connected to
the strap fork ŕ and under the influence of a spring. in combination with a thread
guard supported by the thread and having a nose u¹, which when the thread
breaks comes into the course of a pin 60, whereby the bar t is disengaged and by its'
spring caused to slide and guide the strap onto the loose pulley.
