Improvements in Spinning and Doubling Machines for Hemp, Jute,
Flax, and other Fibrous Material.
I, JACOB HEINRICH BEK, of Stockach, Baden, Germany, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to essential improvements in or relating to spinning
and doubling machines for hemp, jute, flax, tow, cotton, and the like, by which
owing to new means the out-put of such spinning and doubling machines is con-
siderably increased.
The means hitherto used for increasing the out-put consisted in increasing
continually the number of revolutions of the machines. For my purpose i.e. for
manufacturing principally strong threads, that is to say threads or yarns having
a thickness up to 3 m. m. and serving in particular for the manufacture of ropes,
the limit of what is admissible has been reached in proceeding in the known
manner.
In exceeding a certain number of revolutions of the flyer and of the bobbin
turning with the latter with the same speed not only the external appearance of
the spun yarn suffers (it becomes bristly), but as the bobbins are usually made of
wood, there is also a danger that both the bobbin as well as the large flyer will
burst
I impart therefore to my improved machine only a determined number of revo-
lutions which is subject to no disadvantages, but I increase its output by impart-
ing to the rope threads or to the doubled yarns, after they have left the automatic
nipper behind the drawing-in device a second twist in the same sense as the first
by means of a new mechanical arrangement within the machine, during one
revolution of the flyer. In consequence hereof I can cause the material to be spun
or to be doubled to pass through the automatic nipper with nearly double the
speed of that formerly employed which offers no inconvenience; but as by the new
second twist applied during one revolution of the flyer in the same machine, a
roving machine and a finishing machine are, so to speak, combined with each
other, the output of the machine is doubled and a yarn satisfying all require-
ments and having the same twist as in machines of older construction is notwith-
standing obtained, as the bobbin is actuated in such a manner that it only runs
at a speed coresponding to that at which the drawing-in device supplies its
material.
The arrangement on spinning and doubling machines, the working parts of
which are shown in longitudinal section in the accompanying drawing, serves to
carry out the new manner of working; it is constructed as follows:-
The feeding of the hemp-band A, the arrangements of the automatic nipper B
and of the flyer C behind the latter are those generally known. Within the fiver
there is arranged the new device effecting the second twist of the thread. This
device consists of a frame E which is locsely suspended by means of two arms.
At the left hand end the frame is held by the shaft of the flyer, at the right hand

page_text: by the right bobbin support which is guided by a cross-piece n arranged in the
flyer.
The weight of the frame and the manner of suspension is such that it always
hangs freely downward and never partakes of the rotation.
Guide rollers e carry the thread in the frame before it runs upon the exchange-
able bobbin F which is actuated from the disc f carried by the shaft of the flyer,
a spiral spring g arranged behind the other end of the bobbin pressing the latter
slightly against the disc.
The left bearing arm h of the frame is hollow.
Beside the shaft of the flyer there is provided a vertical shaft i carrying a
worm-gear in such a manner that a worm on the shaft of the flyer actuates an
upper wheel on the said shaft i a lower worm on which transmits its motion to
the wheel and by the shaft of the latter to the conveying spindle / supported
in the frame. This spindle is provided with a right handed and a left handed
screw thread intersecting each other and upon which the last thread-guide m is
arranged as a nut, moving to and fro when the flyer turns.
The above described arrangement works as follows:-
The band A of hemp &c., is led by the transporter a actuated by the gearing b
to the automatic nipper B, and enters the flyer C, the shaft of which is driven
from the lower main-shaft at the left hand by the belt c.
The drawing-in device D is actuated at the right hand by the belt d and the
thread passes therefrom over a guide roller e provided on the fiver C to the
frame E. As the flyer C rotates together with the thread round the station-
ary frame E a second twist in the same sense as the first is given at the stationary
fulcrum o when the thread enters the frame.
The finished twisted thread runs over the guide rollers of the hanging frame E
to the bobbin F rotated by the combined appliances f, g, above described only at
such a speed that the freely suspended part of the rope-thread is just held in a
stretched condition. Owing to the movement of the thread guide m upon the
conveying spindle 7 the thread is uniformly wound in the known manner.
The varn is thus flat roved by the automatic nipper and then spun in the
frame E in such a manner, that a yarn having its fibres uniformly laid one
beside the other is obtained. This gives the relatively strongest possible yarn,
an as the number of revolutions of the spindle is considerably inferior to that
of the flyer, the yarn will be smoother than usual.

Improvements in Spinning and Doubling Machines for Hemp, Jute,
Flax, and other Fibrous Material,
I, JACOB HEINRICH BEK, of Stockach, Baden, Germany, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to essential improvements in or relating to spinning
and doubling machines for hemp, jute, flax, tow, cotton, and the like, by which
owing to new means the out-put of such spinning and doubling machines is con-
siderably increased.
The means hitherto used for increasing the out-put consisted in increasing

page_text: continually the number of revolutions of the machines. For my purpose i.e. for
manufacturing principally strong threads, that is to say threads or yarns having
a thickness up to 3 m. m. and serving in particular for the manufacture of ropes,
the limit of what is admissible has been reached in proceeding in the known
manner.
In exceeding a certain number of revolutions of the flyer and of the bobbin
turning with the latter with the same speed not only the external appearance of
the spun yarn suffers (it becomes bristly), but as the bobbins are usually made of
wood, there is also a danger that both the bobbin as well as the large flyer will
burst.
I impart therefore to my improved machine only a determined number of revo-
lutions which is subject to no disadvantages, but I increase its output by impart
ing to the rope threads or to the doubled yarns, after they have left the automatic
nipper behind the drawing-in device a second twist in the same sense as the first
by means of a new mechanical arrangement within the machine, during one
revolution of the flyer. In consequence hereof I can cause the material to be spun
or to be doubled to pass through the automatic nipper with nearly double the
speed of that formerly employed which offers no inconvenience; but as by the new
second twist applied during one revolution of the flyer in the same machine, a
roving machine and a finishing machine are, so to speak, combined with each
other, the output of the machine is doubled and a yarn satisfying all require-
ments and having the same twist as in machines of older construction is notwith-
standing obtained, as the bobbin is actuated in such a manner that it only runs
at a speed corresponding to that at which the drawing-in device supplies its
material.
The arrangement on spinning and doubling machines, the working parts of
which are shown in longitudinal section in the drawing accompanying my Pro
visional Specification, serves to carry out the new manner of working; it is
constructed as follows:-
The feeding of the hemp-band A, the arrangements of the automatic nipper B
and of the flyer C behind the latter are those generally known. Within the flyer
there is arranged the new device effecting the second twist of the thread. This
device consists of a frame E which is loosely suspended by means of two arms.
At the left hand end the frame is held by the shaft of the flyer, at the right hand
by the right bobbin support which is guided by a cross-piece n arranged in the
flyer.
The weight of the frame and the manner of suspension is such that it always
hangs freely downward and never partakes of the rotation.
Guide rollers e carry the thread in the frame before it runs upon the exchange-
able bobbin F which is actuated from the disc f carried by the shaft of the flyer,
a spiral spring g arranged behind the other end of the bobbin pressing the latter
slightly against the disc.
The left bearing arm h of the frame is hollow.
Beside the shaft of the flyer there is provided a vertical shaft i carrying a
worm-gear in such a manner that a worm on the shaft of the flyer actuates an
upper wheel on the said shaft i a lower worm on which transmits its motion to
the wheel k and by the shaft of the latter to the conveying spindle 7 supported
in the frame. This spindle is provided with a right handed and a left handed
screw thread intersecting each other and upon which the last thread-guide m is
arranged as a nut, moving to and fro when the flyer turns.
The above described arrangement works as follows:
The band A of hemp &c. is led by the transporter a actuated by the gearing b
to the automatic nipper B, and enters the flyer C, the shaft of which is driven
from the lower main shaft at the left hand by the belt c.
The drawing-in device D is actuated at the right hand by the belt d and the
thread passes therefrom over a guide roller e provided on the flyer C to the

page_text: frame E. As the flyer C rotates together with the thread round the station-
ary frame E a second twist in the same sense as the first is given at the stationary
fulcrum o when the thread enters the frame.
The finished twisted thread runs over the guide rollers of the hanging frame E
to the bobbin F rotated by the combined appliances f g above described only at
such a speed that the freely suspended part of the rope-thread is just held in a
stretched condition. Owing to the movement of the thread guide m upon the
conveying spindle 7 the thread is uniformly wound in the known manner.
The yarn is thus flat roved by the automatic nipper and then spun in the
frame in such a manner, that a yarn having its fibres uniformly laid one
beside the other is obtained. This gives the relatively strongest possible yarn,
and as the number of revolutions of the spindle is considerably inferior to that
of the flyer, the yarn will be smoother than usual.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:-
1. Spinning and doubling machines wherein the yarn has imparted to it
during one revolution of the flyer two separate twists in the same direction,
namely in addition to the ordinary twist imparted at the entrance of the yarn
into the flyer, a second twist imparted at a fixed central point o round which the
flyer turns, the yarn being led from such point over a stationary frame E to the
bobbin, substantially as described.
2. In a spinning and doubling machine such as is referred to in the first claim,
arranging the bobbin F between a frictional disc carrier f on the flyer spindle
and a spring g which presses the bobbin against the disc, whereby the speed of
rotation of the bobbin is regulated according to the delivery of the yarn from the
flyer, substantially as described.
3. In a spinning and doubling machine such as is referred to in the first claim
the arrangement of the transport spindle for winding the thread regularly on
to the bobbin, whereby it has imparted to it the requisite rotary motion by means
of worm and worm wheel gear mounted in the frame E and receiving motion from
the flyer spindle, substantially as described.
4. Spinning and doubling machinery for imparting two consecutive twists to
the yarn, arranged and operating as herein described with reference to the
drawing.
