To all whom it may concern:

Be it known that I, JAMES CLAYTON, of 12 Mlddleborough road, Coventry, in the county of Warwick, England, have invented new and useful Improvements" in Apparatus for Use in the Manufacture of Artificial- Silk and Like Threads, of which the following is a specification.

This invention relates pr ncipally to ap paratus whereby artificial silk, and like threads, are produced by precipitating mat-.

ter, such as a viscous preparation of cellu lose, such as viscose, (we will, for the purose of description, refer to it as viscose), into a setting medium, or bath, through. perforatlons n a nozzle to form a number of filaments which are twisted together to hitherto and whereby the spinning, or twistpositive gearing driving the the action of the pump ing, of the filaments into thread is eificiently effected as the filaments issue from the orifices in the forming nozzle into the setting medium, or bath. Attempts have before been made to effect the spinning, or twisting, of filaments of viscose as they issue from the forming nozzle, but the means hitherto devised for the purpose have not been suitable for practical application and have not been successful. It is necessary, in the apparatus to which this invention relates, that rapid rotation shall be imparted to the'hoh low stem, or spindle,'carryin the nozzle by hollow stem, or spindle, at some portion of its length between the two ends, and that the viscose shall be supplied at the end opposite to that at which the nozzle is fixed.

According to this invention, the stem, or spindle, is carried on a swinging frame,

capable of being turned in a bracket secured to the viscose supply.pipe,-so as to bring the nozzle into convenient position for inspection, or other purpose, and at'the same time put out of gear the wheels which trans-.

mit motion to drive the stem, or spindle. The pump is also so mounted on the said frame that it can be swung thereon to disengage the gear which drives it and so stop when desiredindependently of the swinging of the said frame, so that, while the frame can-be swung to' put the stem, or spindle, in and out of gear without affecting the driving of the pump, when desired both can be put into and out of ear simultaneously. The said frame carries the filter and the various parts are erforated for the passage of the viscose mm the viscose pipe to the pump and from the pump through the filter and frame to the stem, or s indle, and thence to the nozzle. The thread w ich is formed by the spinning,

of the stem, or spindle, and nozzle, is led over suitable guides to a winding reel, or the equivalent, provided with means for. driving it and preferably also with means for 1aying the thread as it is wound, and the said reel,

or the equivalent, is mounted so that it can, by any suitable device, be put out of gear with the driving means and removed and replaced by another reel, or the equivalent,

or twisting, of the filaments, by the rotation 65 as required. The driving means. for the'75 the stem, or spindle, and the reel, are geared together so that they have the required relative speeds, which can be altered ifvdesired by change wheels. The arrangepump,

ment is preferably such as to include a numher of devices as described, arranged in two rows back to back.

The following is a description (with ref-- erence to the aeeompanylng drawings) of a construction and arrangement of appara-,

tus in accordance with this invention, but

the invention is not limited to the precise details hereinafter described.

Figure 1 is an end elevation, Flg. 2 a

adjuncts removed), and Fig. 3 a transverse section, of theapparatus. Fig. 4 1s a sec tion of one of the rotatable nozzles and lts stem, or spindle, and means for supplyin viscose thereto, and of one of the pumps an the driving gear in connection with the said ump and stem, or-"spindle. This and the ollowin figures are drawn to a larger scale. ig. 5 is an end view of the frame carrying the pump and stem, or spindle, and Fig. 6 is a section showing a pum and stem, orspindle, in position in such ame and the supportin bracket. Fig. 7 is a longitudinal section s lowing the gear by which the stems, or spindles, are driven.

The arrangement illustrated shows two baths with six arrangements of nozzles and pumps in connection with each. but it 18 side elevation (with some of the pumps and to be understood that one bath, or any number of baths, and one pumand nozzle, or

any-number of pumps an nozzles, can be used with each bath.

On a suitable framework 1, are carried two setting baths 2, parallel with each other, and outward of these baths are standards 3, for a driving shaft 4, each shaft 4 carrying friction wheels 5, one for drivin eachstem, or spindle, of the squirting nozz es, as hereinafter described. Below this shaft 4 and its standards project brackets 6 carrying a pumpdriving shaft 7, geared at the end, preferably by change gear 8 (see Fig. 1) to the driving shaft 4. On this pump-driving shaft 7 are worms 9, one for each pump. A pipe 10 for the supply of viscose runs along each side of the machine and to each of these pipes 10, opposite each of the worms 9,

on the pump-driving shaft 7, are fixed continuations 11 of the bracket 6, these continuations having bearings by which a frame is carried, as shown clearly in Fig. 6,

- the sa-id'frame preferably consisting of two arms, 12 and 13, .and two cross-pieces 14 and 15. The said frame can be swung on, or in,- the said bearings as centers. In bearings, respectively in one of the said arms (that marked 13) and'in the bracket 11, secured to the viscose supply pipe 10, is carried the pump 16, so that it can be swung in these bearings as centers. The arms 13 each carry a filter 17. The upper cross-piece 14, between the arms 12 and 13, carries, in a clamp 18, one end of the casing 33, with a bearing for one end of the stem, or spindle, 19, terminating in the nozzle 20, through which the viscose is squirted into the bath.

The stem, or spindle, 19 of the nozzle 20 carries around it, preferably near the ,midpart of its length, a quick-threaded worm 21, which engages with a worm-wheel 22, carried on a spindle 23, mounted in bearings 24 (preferably ball bearings) carried by a casing 25, which is secured to the lower cross-piece between the aforesaid arms 12 and 13. The said worm-wheel 22 has formed on, or fixed to, it a friction wheel 26 which, when the frame is swung toward the bath, bears against the corresponding friction wheel 5, carried by the driving shaft 4. When the pump 16 is swung toward the bath, the worm-wheel 27 of the pump engages with one of the worms 9 carried by the pump-driving shaft 7 and then viscose is pumped from the viscose pipe 10, through a perforation in the said pipe and through a perforation 28 (Fig. 6) in the bracket 11, which carries the aforesaid frame, through the erforations 29, to the pump 16, and there rom through a perforation 30 in one of the arms and through the filter17, and therefrom through a perforation 31 in the upper cross-piece 14 of the frame into a chamber 32 in a piece 41 rease in the casing 33 which piece carries the adjustable bearing for one end of the stem, or spindle, of the nozzle, and thence by the lateral perforations 34, in the said bearing of the stem, or spindle, into the longitudinal perforation 35 in the stem, or spindle, which thus communicates at one end with the said chamber 32, and, at the other end, with the nozzle 20. The stem, or spindle, 19 which carries the nozzle may be carried in bearings in its casing in any suitable way,'for example, as shown in Fig.4, the end of the casing nearest the nozzle 20 may have a ball-seating 36, secured to it, and another ball-seating 37 secured to the stem, or spindle, 19, antifriction balls being interposed between these seatings, andthe end of the stem, or spindle, 19, at which the viscose enters may be made with a conical seating 38, into which enters a correspondingly coned end 39 of a screw 40, perforated to a sufiicient extent to form a continuation of the perforation 35, in the stem, or spindle, to the chamber 32, through the transverse perforations 34, the said screw 40 being screwed through the piece 41 in the end of the casing 33 of the stem, or spindle, so that the bearing can be readily adjusted.

Between, and above, the baths2the framework of the machine carries standards 45 with bearings in which a reel-driving shaft 46 is mounted, this shaft 46 being driven by gearing 47 and 48 (connected by the inclined shaft 49) from one of the driving shafts 4 from which one series of the rotary nozzles and stems, or spindles, and pumps derive motion as aforesaid. Extending outward from each side of the upper end of .each of the standards 45, which support the ing connection with the driving gear, and

remain stationary. The driving is effected by making the extensions from alternate standards 45 in the form of hollow casings, as shown in Fig. 3, and carrying a short spindle 5.6 at the outer end of each such casing. Secured to this spindle 56, inside the casing, is a chain-wheel 57, driven by a chain 58 from a chain-wheel 59 of a series of such wheels on the shaft carried by the e standards as aforesaid. The ends of the said short spindle which project from the casing each carry a friction, or gear, wheel 60 driving two adjacent reels by contact, or engagement, with friction, or gear, wheels 61 on the axes of the said reels. The driving frame, a perforated bearing piece'opening shown at 62) may be operated in proximity with each reel for properly laying the of the reels atone side is effected through I. an intermediate wheel so that the reels on the respective sides rotate in opposite directions.

Any suitable thread-layers (such as those thread-being wound thereon. The thread layers 62 are shown as being caused to swing by means of an eccentric 66 on the inclined shaft 49, the said eccentric being connected by a strap and rod 67 to a bar 68 to which the said thread-layers 62 are connected in any suitable manner.

The arrangement described for winding directly onto reels may be varied, for instance the thread may be wound onto bobbins driven as described withregard to the reels, or the thread may be coiled in suitable receptacles, by a coiling arrangement, or be otherwise dealt with to prepare it for subsequent treatment.

The various parts which it is desirable to protect from acid and to shield so as to avoid danger of accident to operatives may be inclosed in any suitable casings, either as indicated in the drawings, or in any other suitable manner, and open where necessary to allow gearing to engage.

Trays may be arranged in any suitable position (as at 63 for-instance) to catch any viscose which may drop from the-nozzles, or be expelled therefrom, when they are out of the bath, and in getting the devices into working order before the nozzles are introduced into the bath.

'At 64 are shown the fast and loose pulleys and band-shifting arrangements for starting and stopping the apparatus at each side.

5 are stops for preventing the frames turning too far and for supporting them when the nozzles are raised from the baths.

The invention may be applied to one, or any'required number, of squirting nozzles, baths, pumps, and reels, in series, arranged in any convenient positions.
