To all whom t may concern:

lowing is a specification. l0

My lnvention relates to thespinning, or

\twisting,process in manufacturing artificial silk from viscose, or like cellulose solution,

` according to what is known as the Topham system wherein, in the apparatus at present most usuall employed the viscose, or like cellulose so ution, is forced through small orifices in stationar nozzles into a setting .bath the resultant fi aments being passed together under guides in the bath and then over drawing rollers, known as goddets, and thence through funnels into rotating spinning boxes by the action 'of which spinning or twisting-of the filaments takes place between the ends ofthe aforesaid funnels and the points at which the filaments leave the drawing rollers, or goddets. The rate of spinning, or twisting, is therefore limited to the speed' at which the spinning boxes can be rotated. v t

The object of this invention is to effect the spinning, or'twisting, operation at a greater rate than has hitherto been attainable and I effect this .by causing supplementary spinning, or twisting,'to take place from both ends in opposite directions that is, in machines of the type aforesaid, between the point at which the viscose, or like cellulose solution, issues from the jet into the setting bath andthe point at' which the filaments, or thread, reaches the guide immersed in the bath, as well as between the drawingroller, or goddet, and the end ofthe funnel as aforesaid.v To effectv this 1.supplementary spinning, or twisting, I impart to/the spindles carrying the nozzles, rotary movement in a direction the reverse of that in-which the spinning boxes rotate. This rotation of the spindles is preferablyefected b y means of a small electric motorjn connection with each spindle.

I 4Will'describe, with reference to the accompanying.. drawings, an arrangement in accordance wlth mg invention, but itis to be understood that do not limit myself to the precise details hereinafter described with reference tothese drawings.

Figure l is a vertical section, Fig. 2 a plan, and 3 a side elevation of so much of an apparatus for the manufacture of artificial silkas is necessary to illustrate the application of my invention thereto. Fig. liis a sectional detail hereinafter referred to.

The apparatus illustrated is one in which the spinning, or twisting, devices are arranged 1n double lines, but it is to be 'understood thatmy invention is not limited to apparatus' arranged in that particular Wa i n the drawing A are the spindles carrying the nozzles athrough orifices in which the viscose, or like cellulose solution, is forced into the setting bath B. The guides in the bath,under which guides the filaments are passed from the npzzles a, are marked b. The drawing rollers, or goddets, above are-marked C, the rotating spinning boxes are marked D, and the funnels.i

through which the threads pass from the said drawing rollers or goddets, to the said spinning boxes are marked E. These parts are, or may besupported,and arranged, in connection with the various other parts of the apparatus illustrated, in the customary manner and therefore it is unnecessary for me to describe, or illustrate, them further than is needed to explain the application of my invention thereto.

According to my invention I-impart to the spindles A, carrying the nozzles a, ro-

.tary motion in a' direction the reverse of that imparted to the spinning boxes D; that is to say, if the spinning boxes D, be rotated ina counter-,clockwise direction the rotation of the spindles A, will be in a clockwise direction. l

For the purpose `of thus rotating the spindles A, I have illustrated,(see the section Fig. 4;).for each spindle, the rotor, or armature,'f, of a small electric motor, A affixed to the spindle, the stator, or field coils f2, of the motor, being, carried by the casing G, Vshown-as being connected to the part h I into which the inner end-'of the spindle A, opens to receive viscose, or llke cellulose solution, from the'supply pipe H, the said casing-G, being 'provided with a long ballbearing g for the spindle A.

The small motors for driving the spindles source as that which lsupplies the motors.

' I, which drive the spinning boxes.`

What I claim is 1. In the manufacture of artificial sil from viscose, or like cellulose solution, the step of spinning or twisting together in one direction a group of filaments substantially as they are formed, and leading lthe thus twisted filament `group to a collecting member rotated in the opposite direction to impart a further twist to the filament group.

2. In apparatus forspinning artificial silk from viscose, or like cellulose solution, a setting bath, a rotary spinning nozzle through which a plurality of jets of cellulose solution are introduced into the bath to form a group of filaments twisted together, in combination with a spinning box 'rotated in opposite direction to the spinning nozzle to impart a further twist to the filament group, and means for leading the filalnent group from the bath to the Spinnin ox.

3.- In apparatus for spinning artificial silk from viscose, orlike cellulose solution, a rotary spinning box, a rotary spinning nozzle, an electric motor for rotating the nozzle in a direction opposite to that of the spinning box, and guides for leading the twisted filament group from the spinning nozzle to the spinning box.

4. In apparatus for spinning artificial silk from cellulose solution, a palr of oppositelyI rotated twisting members for twisting together a group of filaments, a setting bath with which one of said members is associated, and means for guiding the filament group from one twisting member vto the other. f

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
