Improvements in Roving, Spinning, Twisting, and like Machines.
We, ROBERT PRAUSE, General Manager, and ALOIS HEEL, Spinning Manager, of
the "Ersten österr. Jutespinnerei und Weberei," the former of Spinngasse, No. 404, :
Vienna XI, Austria, and the latter of Neupest, Budapest, Hungary, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in spinning and twisting machines where- .
by, in consequence of, first, the special construction or arrangement of the flyers and
the bobbin-stands, and secondly, the disengaging devices with which the flyers are
severally provided, and the doffing and tension arrangements of the bobbin-stands,
there are secured a considerably higher efficiency both as regards the quantity and
as regards the quality, of the resulting product, and also a considerable saving in
power. These improvements, which can be readily applied to existing spinning-
machines and can be employed for both roving and finishing frames, in dry spinning.
and wet spinning, and also for twisting or doubling, render practicable, in addition to
an 'increased production, in consequence of a greater speed of revolution, and a
saving in power and lubricants, both a lower degree of twist in the yarn and a finér
spinning of even low-quality textile fibres, and also a more rapid removal of the'.
bobbins, whilst in case of breakage of the threads, neither a loss of power nor of.
material is incurred.
A twisting or doubling-machine according to this invention is illustrated in the
accompanying drawings, in which Fig. 1 is half a vertical cross section and half an
end view thereof; Figs. 2, 3, and 4 are an end elevation and two longitudinal sections
showing the arrangements for doffing and for throwing the flyers out of gear;
Fig. 5 shows one of the flyers to a larger scale; and Figs. 6, 7, and 8 are views of
the drag or tension device.
As shown, the flyers a are arranged entirely separate from the spindles and the
bobbins b.
Each flyer consists of a stepped pin or flyer-head a¹ in the lower enlarged portion"
of which are screwed the two flyer legs, whilst the pin or head itself carries the
wharl a³ between two bearings a², of which the upper is adjustable. The bearings a²
are mounted in a forked arm.c¹. All the arms c¹ are fixed to an angle bar c extending
the whole length of the machine. The flyer is prevented from falling out of the
bearings by means of the wharl 3, and the lubrication of the bearings a² is effected
by means of oil-grooves a of which the one in the upper bearing is protected from
dust by means of a cap a³.
The thread coming from the drawing apparatus passes through the hole in the
flyer-head on to one leg of the flyer and through its eye at on to the bobbin b.
The wharl a³ is driven by means of a pulley d, which is keyed upon a driving
shaft and next to which is arranged a ring. f which is fixed on a carrier f¹ and
upon which the wharl cord is pushed when it is desired to disengage the flyer a.
Rib-like projections d² cast on the driving pulleys d serve to facilitate the passage
of the cords on to their respective rings.

page_text: Each of the disengaging devices comprises a fork g secured to a pivoted lever g¹,
which is connected at one end to an adjustable spring g² tending to hold the fork
in the position of engagement or.to: restore it thereto, and which is connected at
its other end by means of a rod g³ to a corresponding pedal-lever 94, by operating
which the wharl-cord is pushed on to the ring f, so as to disengage the flyer.
In order to keep the flyer out of engagement for a lengthy period, there is
provided a catch h which prevents the pedal-lever g₁ from moving back and which
is pivotally suspended in such a manner that when the pedal-lever is at rest, i.e.,
in its highest position, the catch.lies in an inclined position against a projection 95
in the foot-plate, and when the pedal-lever is depressed, the catch falls in con-
sequence of its own weight, and the projection 95 enters and engages in a notch
formed in the lower end of the catch h.
The bobbin-stand comprises a shaft k, which extends the whole length of the
machine, and upon which is fixed for each flyer a four-armed bobbin-carrier m.
The carrier m is formed in two parts and into four holes made in it at right angles
to each other there are screwed pins or spindles m¹, which carry the bobbin-plates b¹
and the bobbins b. For the purpose of moving the whole bobbin-stand up and
down, the shaft k rests upon rods m², which are movable vertically in bearings m
and can, by means of chain-pulleys n¹ mounted on a shaft n, be raised and lowered
in the ordinary manner through the intermediary of lever mechanism operated by a
heart-shaped cam o or the back drawing-roller shaft.
In order to enable the bobbins to be rapidly removed or changed when the bobbin-
stand is lowered, there is mounted loosely on the end of the shaft ka wheel p,
having a four-sided hub p¹ which is prevented from rotating but is capable of moving
in a vertical slot p² in the framing of the machine. On the shaft k there is fixed a
crank q having a projection q¹ carrying a spring-pin q2, which, during the rotation
of the crank engages in one of the holes 23, of which there are four, that are
provided in the periphery of the wheel in positions corresponding with the bobbins
placed upon the carriers m. When one row of bobbins is full and the machine has
been stopped, the pin q2 is drawn out of the hole and then the crank is rotated
through 90° until the pin engages in the next hole.
The full bobbins, which have thus been brought into a horizontal position, can
now be readily removed, and in the meantime a row of empty bobbins have been
brought into a vertical position under the flyers and are filled with yarn by the
restarted machine during the operation of changing the full bobbins for empty ones.
The empty bobbins, which are brought, during the next quarter rotation of the
bobbin-stand, downwardly into a vertical position, are held firmly upon the bobbin-
pins by means of a device by which at the same time the braking of the bobbins
for the purpose of regulating the frictional resistance can be effected.
This device comprises a cord which can be placed in a groove 62 in the bobbin-
foot with more or less tension along a greater or smaller part of its periphery, the
cord being fixed at one end to a projection 63 on the bobbin-plate 61 and at its
other end to a sliding-piece r¹, which can be adjusted by hand and is rotatable
about the bobbin-pin m¹. This sliding piece has a spring tooth 2, which, when the
sliding piece is rotated, can engage with teeth 3 provided on the bobbin-plate and
so fix the sliding piece.

We, ROBERT PRAUSE, General Manager, and ALOIS HEEL, Spinning Manager, of
the "Ersten österr. Jutespinnerei und Weberei," the former of Spinngasse, No. 404,
Vienna XI, Austria, and the latter of Neupest, Budapest, Hungary, 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 improvements in spinning and twisting machines whereby,
in consequence of, first, the special construction or arrangement of the flyers and the
bobbin-stands, and, secondly, the disengaging devices with which the flyers are
severally provided, and the doffing and tension arrangements of the bobbin-stands,
there are secured a considerably higher efficiency both as regards the quantity and
the quality of the resulting product, and also a considerable saving in power. These
improvements, which can be readily applied to existing spinning-machines and can
be employed for both roving, yarn, and like frames, in dry spinning and wet spinning,
and also for twisting or doubling, render practicable, in addition to an increased pro-
duction in consequence of a greater speed of revolution, and a saving in power and
lubricants, both a lower degree of twist in the yarn (when used in yarn-frames and a
finer spinning of even low-quality textile fibres, and also a more rapid removal of
the bobbins, whilst in case of breakage of the threads, neither a loss of power nor of
material is incurred.
A twisting or doubling machine according to this invention is illustrated in the
drawings filed with our provisional specification in which
Fig. 1 is half a vertical cross section and half an end view thereof;
Figs. 2, 3, and 4. are an end elevation and two longitudinal sections showing the
arrangements for doffing and for throwing the flyers out of gear;
Fig. 5 shows one of the flyers to a larger scale; and
Figs. 6, 7 and 8 are views of the drag or tension device.
As shown, the flyers a are arranged entirely separate from the spindles and the
bobbins b.
Each flyer consists of a stepped pin or flyer-head a¹ in the lower enlarged portion
of which are screwed the two flyer-legs; whilst the pin or head itself carries the
wharla between two bearings a², of which the upper is adjustable. The bearings a²
are mounted in a forked arm c¹. All arms c¹ on one side of the machine are fixed to
an angle-bar e extending the whole length of the machine. Each flyer is prevented
from falling out of its bearings by means of the wharl ; and the lubrication of the
bearings 2 is effected by means of oil-grooves of which the one in the upper
bearing is protected from dust by means of a cap a³.
The thread coming from the drawing apparatus passes through the hole in
the flyer-head on to one leg of the flyer and through its eye a on to the
bobbin b..
Each wharl, a³ is driven by means of a pulley d, which is keyed upon a driving
shaft d¹ and next to which is arranged a ring f which is fixed on a carrier f¹ and upon
which the wharl-cord is pushed when it is desired to disengage the flyer a. Rib-like
projections d² cast on the driving pulley d serves to facilitate the passage of the
cords on to their respective rings..
Each of the disengaging devices comprises a fork g secured to a pivoted lever g',.
which is connected at one end to an adjustable spring g² tending to hold the fork in
the position of engagement or to restore it thereto, and. which is connected at its
other end, by means of a. rod g³, to a corresponding pedal-lever g*, by operating which
the wharl-cord is pushed on to the ring f, so as to disengage the flyer.

page_text: In order to keep the flyer out of engagement for a lengthy period, there is provided
a catch h which prevents the pedal-lever g from moving back and which is pivotally
suspended in such a manner that when the pedal-lever is at rest, i.e. in its highest
position, the catch lies, in an inclined position, against a projection g5 on the foot-
plate, and when the pedal-lever is depressed, the catch falls in consequence of its own
weight, and the projection g³ enters and engages in a notch forined in the lower end
of the catch h.
The bobbin-stand comprises a shaft k, which extends the whole length of the
machine, and upon which is fixed for each flyer a four-armned bobbin-carrier m. The
carrier m is forined in two parts and into four holes made in it at right angles to
each other there are screwed pins or spindles m¹, which carry the bobbin-plates b
and the bobbins b. For the purpose of moving the whole bobbin-stand up and down,
the shaft rests upon rods m², which are movable vertically in bearings m³ and can,
by means of chain pulleys n¹ mounted on a shaft n, be raised and lowered in the
ordinary manner through the intermediary of lever-mechanism operated by a
heart-shaped cam o driven by the back roller-shaft (see the right-hand side of
Fig. 1).
In order to enable the bobbins to be rapidly removed or changed when the bobbin-
stand is lowered, there is mounted loosely on the end of the shaft k a wheel p, having
a four-sided bub p¹ which is prevented from rotating but is capable of moving in a
vertical slot p2 in the framing of the machine. On the shaft k there is fixed a
crank q having a projection q¹ carrying a spring-pin q2, which, during the rotation
of the crank, engages in one of the holes p³, of which there are four, that are
provided in the periphery of the wheel in positions corresponding with the bobbins
placed upon the carriers m. When one row of bobbins is full and the machine
has been stopped, the pin q2 is drawn out of the hole and then the crank is
rotated through 90° until the pin engages in the next hole.
The full bobbins, which have thus been brought into a horizontal position, can now
be readily removed, and in the meantime a row of empty bobbins have been brought
into a vertical position under the flyers and are filled with yarn by the restarted
machine during the operation of changing the full bobbins for empty ones.
The empty bobbins, which are brought, during the next quarter rotation of the
bobbin-stand, downwardly into a vertical position, are held firmly upon the bobbin-
pins by means of a device by which at the same time the braking of the bobbins
for the purpose of regulating the frictional resistance can be effected.
This device comprises a cord r which can be placed in a groove 62 in the bobbin-
foot with more or less tension along a greater or smaller part of its periphery, the
cord being fixed at one end to a projection 63 on the bobbin-plate b¹ and at its other
end to a sliding-piece r¹, which can be adjusted by hand and is rotatable about the
bobbin-pin m. This sliding-piece has a spring tooth r², which, when the sliding
piece is rotated, can engage with teeth provided on the bobbin-plate and so fix the
sliding piece.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In roving, spinning twisting and like machines, apparatus comprising flyers a
arranged separate from the spindles and the bobbins and having stepped heads a¹
each held by means of a wharl in a forked bearing-arm c¹, and a bobbin-stand which
comprises a rotatable shaft k and four-armed bobbiu-carriers m fixed thereon and the.
movement of which relative to the flyers is effected by raising or lowering the shaft k
by means of rods m² which are operated by the back roller-shaft by means of a shaft n
and chain-pulleys n¹.
2. In apparatus of the kind specified in the preceding claim a flyer-disengaging device
comprising a fork g which is acted upon by a spring 92 and can be adjusted by a
pedal-lever g and which is adapted to guide the corresponding wharl-cord from the

page_text: driving pulley d on to a fixed ring f, the pedal-lever being held firmly in its depressed
position by a falling catch h.
3. In apparatus of the kind specified in Claim 1, a doffing-device comprising a
wheel p mounted loosely on the shaft and prevented from rotating, and a crank q
fixed upon the said shaft for the purpose of rotating the same and provided with a
spring-pin q², which, on the rotation of the crank into positions corresponding to the
working position of the rows of bobbins, engages in holes in the wheel p and so holds
the shaft firmly after each quarter rotation, in consequence of which each row of full
bobbins can be removed and changed for empty ones whilst a row of empty bobbins
are being filled.
4. In apparatus of the kind specified in Claim 1, a tension-device which also serves
to hold the bobbins firmly upon the downwardly directed bobbin-pins of the .
bobbin-carriers m and comprises a sliding-piece 71 which is provided with a spring
tooth adapted to engage with teeth on the bobbin-plate and which is rotat-
able in relation to the bobbin-pin m¹ and serves for tightening a cord r, which is
fixed at one end to the bobbin-plate and at the other to the sliding piece, and
which can be pressed with more or less tension against the bobbin-foot.
5. Roving, spinning twisting and like machines constructed, arranged, and
operating substantially as hereinbefore described with reference to and shown in
the drawings annexed.
