To aIZZ whom it may -cortccrnf` Be it known that I, MONTGOMERY WAD- DELL, of New York, inthe county vofy New yYork and State of New York, have invented certain new and useful Improvements in A paratus for Forming Filaments, whereof t e 'In the drawings, Figure I represents a' View, partly in longitudinal section through thevspinning-trough and partly in side elevation of the spinning-tube and its standard, of an apparatus embodying my invention in one of its simpler forms where only a single trough is employed. Fig.V II is an enlarged vertical longitudinal section through the s inning-tube and standard, showin in section the adjacent end ofthe trouv' III is a transverse section throu h tbe stan ard on the line III III of Fig. Il? Fig. IV is a fra mentary vertical section taken on the line IV of Fig. II. Fig. V is a longitudinal section through the spinning-troughs, in

an amplified form, of apparatus where two` troughs re employed, certain features, how.- ever being equally applicable in the case of a singfe trough. Fig. l I is a plan View of the ost of the features of improvement relate to anapparatus in which the spinneret is rotated as it delivers the viscose to the coagulating or so-called settingj solution in order to twist the individual filaments spil-'ally together as they pass` through the settingbath and are coiled 'uponthe winding spool or roller. n .e

Referring to thejsimple type shown in Fi s.

I and II of the drawings, 1 'represents t e' trough adapted to contain the setting solution, said trough being preferably provided with a drip-box 2 at the end adjacent to the spinning device 3, in which any escaping viscose can be' received when the-spinneret is turnedout of its operative position. The

`spinningdevices comprises-an elongatedtube 4, adapted to be projected in an inclined position .into one end of the spinning-trou h, said tubevha'ving an enlarged forward or ischarge end5, upon which the spinneret 6 containing numerouslfine orifices, is secure by means of a screw-cap 7.. The tube 4 has secured to it a pulley 10 and is rotatively mounted'in bearings 8 9, which are respectivelyr supported by arms 11 and 12, which converge to a vertical standard 13. This standard 13, which constitutes both the 'sup. port for the spinning-tube andthe duct for supplying viscose thereto, is secured at its lower extremity to a horizontal base-piece 14, which is pivotally mounted at 15 uponl f the bracket 16. Both the base-piece 14 and the standard 13 `are hollow, the standard being of flattened cross-section, as indicated in Fig. III. The channel 17 in the base-piece 14 leads to a vertical channel 18 in the lower portion of the standard .13; but at a short distance from the lower end thereof the channel has a ltransverse ofi' set leading to an clon-.

gated vertical channel -19, which' extends near the top ofthe standard 13. This chan-l nel 19 has a fiat and relatively wide cross-section, as shown in the sectional view of Fig. III, so as to afford an extended interior surface. nel 19 a second lateral offset leads to the channel 20, `which continues upwardly `through the. arm 11 to. an annular duct 22,

formed in the bearings g8 and surrounding the exterior' of the Spinnin -tube 4. An orifice 23 is formed in said tu e at the region surrounded by the duct, so that the interior of the tube is in constant communication wit the annular channel 22.

At the upper extremity of the chan# A' iiltering-diaphra m 21 of any material i ordinarily employed or the filtration of -vis-- cose or similar substances is arranged vertically Within the elongated flat channel 19 of filtration, thus permitting the travelof the.

viscose through the 4filtering-diaphragm Without requiring excessive pressure. A Web 24, .which unites the standard 13 and horizontal base-piece 14, affords bearing for the flanged pulley 25, having a band which drives thepulley 10. The shaft of said pulley 25 is actuated by means of a friction pulley 26, which in -turn is driven from -the main drivingpulley 27. (See Fig. I.) The Winding IOO roller or spool 28, mounted above the settingtrough, is driven by means of a pulley 29 fromaxis ofoscillatory movement of thestandard 13 and its base-piece 14.`

The details of the connections are shown in vertical section in'Fig. IV. The bracket Y16.

provided with a deep vertical slot 40, the wall 41 ofwhich at one side affords bearing for a set-screw 42. The opposite Wall 43 is perforated with a channel 44, whose end adj acent to the slot is coned, as shown at 45. The other end of said channel is provided with a screw-threaded connection to receive Athe supply-tube 46;leadin from the reservoir of viscose. At the end o the base-piece-14 is a cylindrical plug 47, having a coned end 48, adapted to fit' snugly and move freely in the correspondingly-coned orifice 45. An axial channel 49 is formed in the coned end of the plug and extends upward to a point somewhat beyond the longitudinal center thereof, where it communicates with the channel 17 of the base-piece 14. The width of the slot 40 is such as to permit the plug 47 to be inserted therein and then slipped laterally into positionin. the coned or eing held in place by means of the set-screw 42. The arran ement ermits the standard to be tilted bac into t e position indicated by the dotted lines in Fig. I, and when'thus tilted ordrawn back the nozzle will be vertically above the'drip-box 2, while of course the friction-disk by which the pulley 25 is driven will be removed from contact with its driving-disk 26, so that the spinning-tube will cease to revolve. In the instance shown the necessary friction is afforded by the weight ofthe spinning-tube and its standard, but obviously modifications of this method may be empleyed. The viscose supplied through the base-piece and standard` after being filtered through the diaphragm 21 is led into the annular duct 22 and thence through the orifice 23 into the inclined tube 4, being finally discharged through the spinneret 6 into thesetting-bath, where it forms a group of fibers twisted to ether,`which are led below'the surface o thev bath through the surface of the guide-fingers 31 to the take-u spool 28. The spool 28 is of) such diameter and so mounted with relation to the trough 1 as to at all times maintain some portion of the. take-up surface beneath the level of the llquid in t e trough, thus continually moistening the Wound filament with the solutionv and protracting the action thereof as far as ossible. This arrangement enhances uniornity .and homogeneousness A of the produc In the arrangement shown i; V and 'different character from the initial setting solution in the delivery-trou h. In this in-v insure that some portion of the peripheryI of ce 45, the parts VIit will be noted'that twospinnerets are arranged to deliver into the same trough and also that a supplemental trough is` employed, which may containasolution of stance the filamentsare' con ucted beneath .the guide-rod 39 and thence u ward throughthe'adjustably-mounted -gui e-ngers 34 tothe periphery ofthe take-up

spools

36 and 37. 'Iwo pairs of said spools are shown 1n Fig, VI, each spool being removably mounted upon the horizontal shaft 35, which is so arf ranged with reference tothe trough 50 as'to the windin -s oolshall at all timesbe below the level o t e liquid in said trough.l The guides 34 can be turned so as to deliver filaments to either 'the spool 36 or the spool 37, and `this transfer can be made While the spools are actually running, so that as 'soon asone spool is filled 1t can be removed independently of its fellow and an empty one substituted in itsplace. The process of spinning and winding may thus proceed continuously. It will be noted that the inclined osition of the spinning-tube permits the delivery of the filaments in a direction nearly horizontal, so that they can be drawn for a relativel long distance through the spinning-troug without abrupt change of direction. This nearl horizontal direction of travel also` afford1 filaments as they pass to the spool. Where, as in some instancesthe filaments are delivered vertically downward into the, Spinnin solution these advantages are lacking, and hence one feature of my improvements con'-` sists in the .described arrangement of the tube in an inclined position as distm v guished from a vertical one.

Having thus claim- A 1. Thel combination of a rotatable spinning-tube and spinneret; an oscillatory standard therefor; a main spinning-trough; and a drip-box adjacent to said main spinning-trough; whereby when the' standard is' oscillated to throw the spinneret out of its operative position, said spinneret will be su orted above said drip-box, substantia y-as set frtli.
