invention relates to' improved: apparatus for continuously spinning artificial filaments o'r threads.

. It object of the-invention to 'provide' an improved machine for continuously spinning, manipulating, and. treating artificial threads in which the section. of the: machine carryin the coagulating liquids which are generally the mostcorros'ive is soarranged with respect to tlieliquid after-treating section in which less corrosive liquids are used that there is little opportunity for spray from the coagulating bath: and the thread handling devices associated with the coagulating bath: to be carried over to the: thread as it is discharged trom theatter-treating liquid: section Arranged; intermediate the'coagulating bath and theafter-treatment section, there is provided in accordance'with the objects of this invention, a stretching: zone which forms at com ponentpart of what is hereinafter termedi the' forming section and in which the. thread. may be treated with any suitable plasti'cizing liquid, which in the case of. viscose may be hot'wateror hot dilute acid. These two distinct sections ot the machine: are soarranged that the discharge end of the liquid after-treatmentdevices is at the partthereof farthest from the forming. section and is beyond: the reachof operators employed along. the: coagulating; bath working face of the machine and conversely the forming section-01ithe machine is out of reach of operators employed along the after-treatment-working face of the machine.

A further object is to so arrange the sections of the machine-that the entire spinning: or treating unitof each: single and thread-producing. station. will -be 'readily and: conveniently accessible to=the operators assigned to the-respectiveworking faces of the machine. A further object is to provide" a. spinning machine having a compact liquid after-treatment section in which all ofthe after-treatingiliquids Qex'cluding; the stretching bath: which is herein. considered to constitute a forming liquid distinguished from an after-treating liquid) are: applied to-a' single continuous helix of the thread. The present in vention also provid'es fo'r drying?and/or'collectingi the after-treated yam in: a section providedat a different floor level than that of the coagulat ingand after-treating sections.

A further object is to provide: an arrangement and: system whereby. the driving, mechanism for the thread handling devices in boththespinning; and after-treatmentsections-is constructed and arranged as a compact unit ina housing;

forced into the space betweenthe jacket and the chine.

coagulating bath is removed, suitable openings l5 being provided in the pedestal all along the machine adjacent the top of the trough 5, and one or two suitable exhaust ducts being provided, such as at one or both ends of the machine, .and being connected to exhaust. fans. .Similarly a duct l6 extending the length of the machine is provided in the upper region of the hood-l1 comprising suitable sash .means Ala by which the spinning stations of the machine are readily accessible to the operators. The duct I6. is provided with openings l3 (preferably adjustablein any conventionalmanner) in. the base thereof facing the receptacle orreceptacles 19 for the plasticizing liquid. Theprovision of the upper exhaust duct l6 and that in the pedestal 9 assures that the foul air will be drawn, away from the operators while they are manipulating the. thread in lacing up the machine or tending to it at any other time. In addition, the provision of an inert gaseous medium under elevated pressure within the jacket l3 about the housing for the ,driving mechanism protects :this mechanism;fro m ,any foul, corrosive atmosphere that may hover about the coagulating section of the machine,

The driving godets of the, devices 1 are set at an acute angle to the longitudinal axis. of the machine .so that they are offset laterally and axially from each otherinistaggered relationship. The reelslZ are, similarly staggered so that, the threads proceed at an acute angle from the upper godets through their respective troughs .l Sto their respective after-treating reels. l 2. By thisar rangement, it is possible to obtain a long immersion through the stretch baths in troughs I 9 without having the receiving endsof the reels 12 beyond the reach of operators having average arm length; Preferably, .the troughs 19 are .I laced from three to five feet fromthefioorlevel. The troughs l9 may be supplied with liquid, such as hot water or hot dilute acid, by the downwardly extending branches 20 0f the feed pipe 2! and adjacent each end with the slotted partitions 22 forming overflow chambers at each end of'the trough which discharge in drains 23.

The reels l2 may be provided with a surrounding deflector or guard 24 for controlling the action of the liquids upon the threads" and substantially confining the'severaldifierent liquids applied-to their respective treating zones along the helix. This defiectoror guard may be 'of the same construction as'that shown in either of the copending applications of Stanley and Lowe, Ser. No. 504,664, fi1ed October 2, 194-3; andSer. No. 523,402, filed February 22, 1944; Headers 25' havingbranches 26 conduct the-severaltreating -15 main housing walls from a suitable duct Ha (Fig. 2) or ducts at one or both ends of themae The hollow pedestal constitutes a duct through which the foul air in the vicinity of the liquids to corresponding treating zones of the helix formed on the reels l2. Discharge pipes 21 connected to the extreme limits of each treating zone lead to troughs 28 which extend the length of the machine for receiving the discharge from the corresponding zones of all the reels l2. The

discharge from each of these troughs may be recirculated to the appropriate header, with or without first subjecting it to recovery, replenishment, or purification processes. The troughs 28 or any selected one or more thereof may be a replaced with headers connected to pipes 21 in An inert'or"" non-injurious gas, such as air,..preferably..dry, is

which case the removal of liquid from the re- .spective treatingzones may be assisted by suitablesuction pumps inserted in the respective headers, especially for operating in accordance withthe above-mentioned application Serial No.

-- inwardly and downwardly sloping trough 29 may be disposed beneath the several troughs 28 and preferably extends to a point beyond the discharge ends of the reels l2.. A trough 39.sloping toward one end, or from the middletoward both ends, of the machine serves to discharge any drainings from the trough 29. The reels #2 are preferably removably supported at both. ends, being coupled for driving at their inner ends and rotatably to a series of posts 3i which are capable of being swung outwardlyon their pivots 32 for removin the reels and of being locked in reel-supporting position by the latches 33, Reels 82 are preferably driven at higher peripheral speed than the devices I so that apredetermined amount of stretching occurs asthe threads pass through the troughs IS.

The threads proceed substantially vertically downwardly from the discharge ends of the reels I! either to centrifugal collecting buckets 34 through the traversing funnel guides 35 as shown in Figure 1a (where alternate threads are directed by godets 3B and 31 to the opposite row of buckets). orthey proceed (as illustrated in Figure 1') to any suitableform of dryin means such as the heated casing 38 in which the respective thread is advanced in the formofa helix about two

canted drums

39 and 49, at least one of Which is driven, and then to a collecting device, such as the winding machine 44 If desired, the winding machine maybe replaced by a cap-twisting or ring-twisting device.

-As shown'in the drawing, the bath for coagulat ing the filaments or threads is preferably narrow and this is necessary in order that an operator standing at the coagulating bath Working face of'the machine can readily reach over the bath to pass the threads through the stretching troughs l9-and place them on the receiving ends oi' the reels [2. As shown in Figures 3 and 4, the connections to supply the spinnerets 9 with spinning material extend through apertures 42 in the outside wall 43 of the trough 5 for the coagulating bath. A bearing 44 of suitable material, preferably resistant to corrosion by the coagulating material is secured in the aperture, such as by welding, so that its axis is inclined in a horizontal plane at a small acute angle, preferably less than 25, tothe normal to the length of the machine.- The rounder 45 preferably is made of a c-orro-= sion-resistant material; such as stainless steel tubing or piping, and. :has'an approximately rightangle bend'at 46 sp'aced a short distance from the wall 43 of the coagulating loath trough. The portion' of the rounder extending through the wall 43 isprovided with a shoulder 4'1 and is clamped within'a sleeve 48 (which is rotatable :within the astern? bearing 44) by the nut to engaging a threaded portion of the rounder. A hand-wheel 50 positione'd outside the. trough is fixed upon the 'sle'evesothat it can-be used to rotate the-rounder and thus swing the spinneret into andout of the trough. A washer 51 of resilient material, such as soft rubber or synthetic rubber, is provided so that it is forced by hydraulic pressure againsta suitable seat or face 52 formed on the bearing 44, thereby sealing the joint against leakage. A hollow region 53 may be formed in the bearing-member 44 and may be provided with a suitable drainage connection 53a (Figure l). The sleeve :18 may beprovided with grooves 54- to prevent any liquidleaking from the bathfrom proceeding beyond the region 53 provided with suitable drainage. An L connection 55 connects the tube 56 which receives the spinning material from the pump 5? to the rounder, a ball and socket joint being provided at '58 topermit rotation of the rounder 45 relative to the L 55. A spring pressed pin- 59 mounted in the bracket Bil maintains the L 55 firmly in engagement with the rounded end of rounder d5.

The rounder 45- has a long straight portion extending from the bend it which merges at 45c with a portion which curves back so that the spinneret 6 at the endof the rounder directs the filaments or thread produced thereby in an upward direction. This curved portion is bent at 45o-so that it lies in a plane approximately parallel to the Wall 43 of the trough when disposed in spinning position. It will be seen from Figure 2 that when the rounder is swung into inoperative position, the spinnerct is directed downwardly over the waste or draining trough 5! which may be provided with removable waste trays 62'. Preferably, the width of the inner web 63 of the bracket 50 is so correlated with the disposition of the spokes 54 of the handwheel 5% that the upper and lower edges of the webit serve as detents to limit the rotation of the handwheel to dispose the spinneret in operating position and in inoperative position over the waste trough 6 i. It will be seen from Figure 4 that the rounders are so constructed and arranged as to permit immersion of the spinneretto a great depth, swinging the spinneret to a'point near the bath surface for lacing up the machine and swinging the spinneret to a point over the waste trough, without interfering with each other and the walls of the trough in spite of its narrowness and depth. In Figure 2, the dottedline [1-2; shows the extreme limit of movement of the rounder away from the wall 43 of trough 5'.

In' starting the spinning operation, the operator turns the handwheel so until the spinneret is at or near the surface of the coagulating bath, threads up the thread handling device 1 and as the thread is taken up thereby he lowers the spinneret to the bottom of the trough 5, and then takes the thread from the device i through one of the stretch baths to the corresponding reel l 2. An operator on the other working face of the machine takes the thread as it is discharged from the reel i2 and drops it to the floor below where another operator receives it and laces up whatever coilecting and/or drying devices ar there. There is no necessity for the operators to carefully synchronize their activitie in that each sectionof the machine can continue to function while waiting fort-he operator in the next section in advance to send the thread on-its way to the next section.

vA. screen Stand a plate 6? separate the bath trough 5v from the drainin trough 6i, The: plate is adiustably mounted so that the depth of the coagulating bath may be controlled readily;
