from Viscous or Semi-fluid Matters.
T, JULES HENRI DU VIVIER, of 61; Rue Blanche, Paris, France, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
It is known that viscous or semi-fluid matters may be drawn out in the form of
threads of various degrees of fineness depending upon the nature of the material
and dimensions of the drop.
My Invention has for its object the production in this manner and on a commer-
cial scale, of textile threads of indefinite length from all kinds of viscous or semi-
fluid matters and more particularly threads of artificial silk from viscous or semi-
fluid matters having a base of pyroxilin in solution in a suitable liquid.
In order that the invention may be more readily understood 1 will proceed to
describe the processes and apparatus I employ for the production of threads or
filaments of artificial silk from a certain compound or material forming the subject
of another application for Letters Patent of even date herewith. These processes
and apparatus comprise more especially (1) the formation of the threads (2) wind-
ing the thread upon a drum for drying (3) winding the thread on to bobbins (4)
doubling and (5) twisting.
I have illustrated the apparatus for performing these several operations, by way
of example, in the accompanying drawings, in which figure 1 is an elevation,
figure a plan; and figure 3 an end view, of the apparatus for drawing viscous
matters into threads. Figure 4 is a plan of a vessel provided with a stirrer used
when the baths through which the threads are to be passed are liable to form a
sedimentary deposit. Figure 5 is a front view, and figure 6 an end view, of the
apparatus for winding the thread upon a drum for drying. Figure 7 shews the
apparatus for winding the thread on to bobbins. Figure S is a front elevation of
the twisting machine, and figures 9 and 10 end views of the same. Figure I is
a plan, on a larger scale, shewing the mode of mounting the small bobbins in the
machine. Figure 12 shews a detail. The same letters and figures of reference
indicate like parts in all the figures.
Referring to figure 1, the apparatus for forming the threads or filaments, consists
of a container a for the matter from which the threads are produced, terminating at
its lower end in one or more nozzles haying orifices of very small diameter
through which the matter flows or is ejected in the form of a thread into a bath of
chemical composition contained in a vessel immediately beneath, the thread,
passing down beneath a guided therein and thence upwards to the guide c and
over the carrying roll into a second bath c of different composition
to the first, and so on in succession through the several baths cc cc being
finally deposited upon a tray y upon which it coils itself in readiness for 'drying.
The drawing represents the threads or filaments as passing through a series
of six baths, the apparatus being arranged in four independent groups, producing
four threads. The number and composition of the baths would however be varied
according to the nature of the thread under treatment.
The shafts which drive the carrying rollers of two parallel series are
made in two parts turning independently, their inner ends being supported in the
central bearings and they are driven by pulleys and bands m. The bath c₂
figure 4, differs from those shewn in figures 1, 2, and 3, in being provided with

For the purpose of drying the threads or filaments,
they are coiled upon a drum p, as shewn in figure 5, the tray g being for
this purpose supported upon a carriage operated by a leading screw, the
thread k, before being coiled upon drum p, being led past guide pins s, to remove
kinks, and then between two guides by which it is laid in an even spiral on
the drum, the guides being supported by, or travelling with, the carriage. The
drum and screw receive rotary motion from pulleys vand bands ay.
The drum when filled is removed from the framing and placed in a drying
chamber suitably heated, after which the dried threads or filaments are wound
off the drum on to small bobbins (figure 7) for which purpose one journal of the
drum is mounted in a forked bearing 1 and the other journal is coupled with the
pulley, which is driven from a band 2 which in turn drives the bobbin z by
pulley 3 and band 4. Two or more of the dry threads are next wound together
upon a single bobbin which is then transferred to the twisting machine repre-
sented in figures 8, 9, 10, by which the threads are twisted together, the degree
of torsion being capable of regulation according to the nature of the thread and
the purpose to which it is to be applied. The machine is driven by a cone pulley b
by which three different speeds may be given to shaft 7 upon which is keyed a
large pulley 8 that drives shaft 9 at an increased speed, the motion being thence
transmitted to shafts 10 by crossed bands I passing round pulleys 12 whereby
different angular velocities may be obtained. Upon each shaft 10 is mounted a disc
13 carrying one or more bobbins 14 perpendicular to the shaft 10 and rotating
therewith so that the threads as they are drawn off become twisted before passing
through the guide 15. The upper set of discs 13 are similarly driven through the
intermediate pulleys 16. The swifts 23 on which the threads are wound to form
hanks are driven from shaft 17, cone pulleys 18 and 19, crossed band 21, shaft 20,
cone pulleys 22 and 24. Or, the threads may be wound directly on bobbins. 25
mounted in brackets 26 fixed to the framing, the bobbins 25 being centred between
bearings 27, 28, pressed together by springs 29; 30, and rotated by a mandrel
driven from shaft 17 by a belt running on the cone pulleys 31 and 32.
pulleys 18, 19, 22 and 23, enable the speed, and the cone pulley 12 enables the
degree of torsion of the threads, to be varied. 33 are clutches for throwing any
part out of action without stopping the entire machine, for the purpose of joining
up a broken thread or replacing a bobbin. The shafts 10 of the twisting devices
are made hollow to contain liquid which may, if desired, be projected or sprayed
upon the thread as it leaves the bobbin by means of a jet nozzle 34 (figure 12)
inserted in the end of shaft 10.

It will be understood that the details of construction, dimensions, and form, of
the apparatus may be varied without in any way departing from the invention.
The apparatus may also be applied for the manufacture or preparation of all kinds
of textile threads.

Improvements in Apparatus for the Manufacture of Textile Threads
from Viscous or Semi-fluid Matters.
JULES HENRI DU VIVIER of 61 Rue Blanche, Paris, France, Manufacturer, 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:-
It is known that viscous or semi-fluid matters may be drawn out in the form of
threads of various degrees of fineness depending upon the nature of the material,

page_text: My Invention has for its object the production in this manner and on a commer-
cial scale, of textile threads of indefinite length from all kinds of viscous or semi-
fluid matters and more particularly threads of artificial silk from viscous or semi-
fluid matters having a base of pyroxilin in solution in a suitable liquid.
In order that the invention may be more readily understood I will proceed to
describe the processes and apparatus I employ for the production of threads or
filaments of artificial silk from a certain compound or material forming the subject
of another application for Letters Patent of even date herewith. These processes
and apparatus comprise more especially (1) the formation of the threads (2) wind-
ing the thread upon a drum for drying (3) winding the thread on to bobbins (4)
doubling and (5) twisting.
I have illustrated the apparatus for performing these several operations, by way
of example, in the drawings accompanying my provisional specification, in which
figure is an elevation, figure 2 a plan, and figure 3 an end view, of the apparatus
for drawing viscous matters into threads. Figure 4 is a plan of a vessel pro-
vided with a stirrer used when the baths through which the threads are to be
passed are liable to form a sedimentary deposit. Figure 5 is a front view, and
figure 6 an end view, of the apparatus for winding the thread upon a drum for
drying. Figure 7 shews the apparatus for winding the thread on to bobbins.
Figure S is a front elevation of the twisting machine, and figures 9 and 10 end
views of the same. Figure is a plan, on a larger scale, shewing the mode of
mounting the small bobbins in the twisting machine. Figure 12 shews a detail.
The same letters and figures of reference indicate like parts in all the figures.
Referring to figure 1, the apparatus for forming the threads or filaments, consists
of a container a for the matter from which the threads are produced, terminating at
its lower end in one or more nozzles having orifices of very small diameter
through which the matter flows or is ejected in the form of a thread into a bath of
chemical composition contained in a vessel c immediately beneath, the thread,
passing down beneath a guide & therein and thence upwards to the guide e and
over the carrying roller downwards into a second bath c' of different composition
to the first, and so on in succession through the several baths c c c c being
finally deposited upon a tray g upon which it coils itself in readiness for drying.
The drawing represents the threads or filaments as passing through a series
of six baths, the apparatus being arranged in four independent groups, producing
four threads. The number and composition of the baths would however be varied
according to the nature of the thread under treatment.
The shafts which drive the carrying rollers of two parallel series of baths are
made in two parts turning independently, their inner ends being supported in the
central bearings and they are driven by pulleys and bands m. The bath c,
figure 4, differs from those shewn in figures 1, 2, and 3, in being provided with
stirrers operated by pulley o. For the purpose of drying the threads or filaments,
they are coiled upon a drum p, as shewn in figures 5 and 6, the tray g being for
this purpose supported upon a carriage 7 operated by a leading screw, the
thread, before it is coiled upon drum p, being led past guide pins 8, to remove
kinks, and then between two guides by which it is laid in an even spiral on
the drum, the guides being supported by, or travelling with, the carriage. The
drum and screw receive rotary motion from pulleys v and bands a y.
The drum when filled is removed from the framing and placed in a drying
chamber suitably heated, after which the dried threads or filaments are wound
off the drum on to small bobbins (figure 7) for which purpose one journal of the
drum P is mounted in a forked hearing 1 and the other journal is coupled with the
pulley, which is driven from a band 2 which in turn drives the bobbin = 'by
pulley 3 and band 4. Two or more of the dry threads are next wound together
upon a single bobbin which is then transferred to the twisting machine repre-
sented in figures 8, 9, 10, by which the threads are twisted together, the degree
of torsion being capable of regulation according to the nature of the thread and
the purpose to which it is to be applied. The machine is driven by a cone pulley (

page_text: by which three different speeds may be given to shaft 7 upon which is keyed a
large pulley 8 that drives shaft 9 at an increased speed, the motion being thence
transmitted to shafts 10 by crossed bands 11 passing round pulleys 12 whereby
different angular velocities may be obtained. Upon each shaft 10 is mounted a disc
13 carrying one or more bobbins 14 perpendicular to the shaft 10 and rotating
therewith so that the threads as they are drawn off become twisted before passing
through the guide 15. The upper set of discs 13 are similarly driven through the
intermediate pulleys 16.
The swifts 23 on which the threads are wound to form
hanks are driven from shaft 17, cone pulleys 18 and 19, crossed band 21, shaft 20,
cone pulleys 22 and 24. Or, the threads may be wound directly on bobbins 25
mounted in brackets 26 fixed to the framing, the bobbins 25 being centred between
bearings 27, 28, pressed together by springs 29, 30 and rotated by a mandrel
driven from shaft 17 by a bolt running on the cone pulleys 31 and 32.
pulleys 18, 19, 22 and 23, enable the speed, and the cone pulley 12 enables the
degree of torsion of the threads, to be varied. 33 are clutches for throwing any
part out of action without stopping the entire machine, for the purpose of joining
up a broken thread or replacing a bobbin. The shafts 10 of the twisting devices
are made hollow to contain liquid which may, if desired, be projected or sprayed
upon the thread as it leaves the bobbin by means of a jet nozzle 34 (figure 12)
inserted in the end of shaft 10.
The cone
It will be understood that the details of construction, dimensions, and form, of
the apparatus may be varied without in any way departing from the invention.
The apparatus may also be applied for the manufacture or preparation of all kinds
of textile threads.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what I claim,
as improvements in apparatus for the manufacture of threads of artificial silk or
other material from viscous or semi-fluid matters, is :-
-
1st. The apparatus for forming and drawing the threads through baths, substan-
tially as described and illustrated in figures and 4.
2nd. The means for drying the thread and winding it upon bobbins, as described
and illustrated in figures 5, 6, and 7.
3rd. The twisting machine whereby the thread is wound in hanks or upon
bobbins, substantially as described and illustrated in figures 8, 9, 10, 11, 12.
