Improvements in or relating to Spinning and Twisting Machines.
I, WILLIAM NEUBAUER, of Bischweiler, Alsace, in the Empire of Germany,
Technical Director of the Elsassische Gesellschaft für Jutespinnerei und Weberei,
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:-
This invention relates to an improved spinning and twisting machine which
differs in principle from the known machines of this kind, and has in consequence.
many advantages.
In the known machines the flyers are so connected that they are also put in
rotation by the driving of the spindles.
In the improved machine only the flyers are put in action and revolve about
stationary spindles, the principal advantage derived is that any single flyer of
the machine can be put in or out of action independently from the others at any
time without trouble and the spinning of the yarn and the exchanging of a spool
at any time when such spool is full is easily operated so that the mechanism for
simultaneous exchanging of the whole of the spools of the machine can be dis-
pensed with. A further advantage of the improved machine is the especially
quiet working of the same as the flyers revolve upon a suitable bearing and are
safely guided by a tubular piece fitting upon the spindle, so that the disadvan-
tageous vibration of the spindles occurring in the known machines is entirely
avoided and consequently repeated dressing of the same often accompanied by
a necessary and expensive renewal of the bearings is also not here required.
Formerly also when removing the spools the flyers being generally screwed o
the spindles, had to be loosened by a wooden hammer which often resulted in th
breaking of a flyer arm or screw shank of the same; in the improved machint
in consequence of the loose mounting of the flyers on the spindles this disadvan-
tage is suppressed.*
Moreover the construction of the machine does not necessitate the use of straps,
bands or cords and consequently no attendance is required for such parts. The
flyers can be readily caused to rotate in the reverse direction independently of
the driving devices of the spinning machine, so that the spinning frame can
also be used for twisting.
In the annexed drawing Fig. 1 is a vertical section of a part of the machine
showing the improvements. Fig. 2 is a section on line x-x of Fig. 1. Fig. 3
is a view from the right of Fig. 1. Fig. 4 is a plan view of a flyer.
The construction of the machine is as follows:-The flyer a is similar to the
hitherto used flyers with the difference that on the flyer shoulder a disk b is fixed
provided with two holes c as near as possible to the flyer arm and the shoulder
(see Fig. 4); from each of these holes a slit d reaches to the edge of the disk for
the purpose of introducing the yarn, further the flyer is lengthened downwards
by a tubular stem f Fig. 1 which fits closely on to the stationary spindle and which
is so long that in the lowest position of the spool frame it still reaches two or

page_text: three centimeters into the wooden spool so that in this manner the revolution
of the spool effected by the winding of the thread is supported by the flyer.
The spindle s may be a round rod or a tube with a bearing point on its upper
end. The upper exterior diameter of the spindle fits into the inner diameter of
the flyer stem so far as the latter extends; from this point downwards, the
spindle has an exterior diameter the same as that of the flyer stem for the same
as the diameter of the bore of the wooden spool. The spindle is journalled
vertically in the two bearings 111 of which is arranged in the usual breast
beam and in the usual step beam. The spindle is lifted by the weight Q by
means of the lever H until the disk b of the flyer comes against a friction
plate composed of papier maché, leather or the like.
The driving of the flyers is effected by the shaft w which is driven directly
from the driving source by means of pulleys. On this shaft are iron disks g g¹ g²
arranged exactly the same distance apart as the spindles between which in round
guides of the cross piece T are the rods kkk movable forwards and backwards.
On each of these rods there is journalled a friction disc 2 movable upwards and
down-wards by means of an arm v; this friction disc is also pressed against the
respective plate g by the weight G rocking the rod k k¹ or by means of lever h.
In the cross piece T there is arranged for each bar k k¹² a guide or projec-
tion which however does not occupy the whole breadth of said cross-piece,
but leaves sufficient room for the front catch piece t arranged on the bars k k₁ k³
and provided with a notch for receiving the guide or projection q. In the work-
ing position disk 12 is prevented from being pushed away from the disk b by
the catch piece bearing against the guide or projection (Fig. 3 third position).
The weight levers H and h are joined together by means of a rod m so as to
move together. If by means of the pedal F fixed on the spindle underneath the
step beam, the spindle is pushed down, then the flyer also goes down and the
disk bis dis-engaged from the friction plate 2 and the flyer stops.
Also at that moment the upper lever arm his lifted by the rod m and thereby
the friction plate 12 is removed from the iron disk g. At the same time also the
catch pivoted on the step beam drops by its own weight and engages the pedal F
and holds the spindle and friction plate in their out of gear position until the
catch is again set free by the operator.
r
If the pedal F is pressed down by the catch p, weight G lifted, and disk 7 is
free, the bar k can be pushed back in its direction of length by means of the
lever D so that the notch of the catch piece t catches into the guide or projec-
tion because in this position of the projection the leather disk 2 is pressed
back so far that the flyers can be easily taken off.
This position of rest is shown on the middle spindle in Fig. 3.
If the flyer is again set in action, the bar k is pushed forward by means of
the lever D so far that the leather disk 12 comes into working position and the
catch piece t lying above the end of the guide or projection can be moved with
the bar and allows the catch p to come again into gear.
If the shaft w is in action then the disk g, the friction plate 12 and the flyer
plate bare put in action by releasing the catch p.
In order to doff or exchange the spool, the flyer is first stopped by the pedal,
then the friction plate 78 pushed backward by the lever D. In order that the
friction disc when in action cannot move away from the driving disc g, the
catch piece of the rod k is provided with a nose which has a hollow correspond-
ing and engaging with a guide g of the beam T when the flyer is out of action.
During working the nose of the catch piece comes against the guide and prevents
the friction disc from moving laterally
The proportional load of the weights G and Q is easily ascertained by first
calculating the pressure of the friction disc upon the driving disc g taking into
consideration the leverage and then making Q of such load that beside effecting
the same pressure upward it also lifts the weight of the spindle and the flyer,
and surmounts the friction in the two bearings 7 11.

page_text: In order to effect the operation of twisting with the spindles, the shaft w with
the disks g is moved a few millimeters towards the left, that is to say so much
that now the left side of the right driving disk is exactly the same distance from
the axis of the spindle as the right side of the left disk was from the same
spindle, then only the levers h with the weights G and the connecting rods m
are moved or mounted so as to operate on the opposite sides of the rods k k¹ k³.
The rod m may also be dispensed with, in which case, in taking away the
bobbin, the spindle s must be first pushed down by the pedal, then by means of
the lever D the bar is turned so far that the notch of the catch piece t will
engage the guide or projection 9, whereupon the rod k and leather disk 1 may
also be pushed back by means of the lever D. The purpose of the rod m is only
to effect the necessary turning of bar by means of the pedal F and make a
further movement (the turning of lever D by hand) unnecessary.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. An improved spinning and twisting machine in which the arrangement of
the flyer a and the spindles is such, that the spindle is movable in the axial
direction but does not revolve and is kept raised by a lever H charged with a
weight or equivalent means so that a friction disk b attached on the flyer a
touches a friction disk 72 so that a revolution of the flyer upon the spindle is
effected by the disk 2 whilst the spool in its revolution is supported by a
tubular stem f of the flyer serving also as guide for the same.
2. In an improved spinning and twisting machine as in Claim 1, the arrange-
ment of a flyer provided with a tubular guiding stem f fitting closely upon the
spindle, the plate 6 of the flyer being provided with two oppositely arranged
holes having slots d for the introduction of the yarn.
