Definitions

  • the present invention relates to the manufacture of silk threads or filaments or silk staple fiber or synthetic silk, or the like and more particularly to an apparatus for use in carrying out some or all of the steps in the manufacturing processes.
  • annular spun fiber cake the form which the material assumes after the setting bath, passing the godet wheel, and spinning box
  • a carrier which includes means for radially spraying liquids against the inner hard compact face of the cake and then causing such liquid to force its way through the cake by centrifugal action.
  • the outer periphery of the cake is unprotected and is free to swell outwardly under the developed centrifugal force.
  • the rotating of the cake during the treating operations causes it to assume an uneven shape, more generally that of an ellipse, with the consequent dense packing of threads at one location while at others there will be a variation due to less dense packing.
  • the general effect is non-uniformity of treatment. Furthermore confining the treating operations solely to the centrifugal flow of liquid through the hard cake makes it necessary to prolong the treatment unduly to ensure that the radial fiow of liquid overcomes the inherent resistance of the cake and completes each step in a thorough manner.
  • Some of the objects of the present invention are to provide an improved apparatus for use in the manufacture of artificial silk having particular reference to the treatment of the preformed fiber cake; to provide an apparatus wherein provision is made for decreasing the treating time of each step without sacrificing the eificiency of such step or steps; to provide an apparatus for use with fiber cakes wherein the treatment of the cake is carried out by a body of liquid moving along a face of the cake and transversely with respect to an applied centrifugal force; to provide an apparatus for use in the treatment of fiber cakes wherein a flow of liquid takes place lengthwise or substantially parallel to the axis of the cake while there is a simultaneous fio-w trans.- versely or radially of the cake; to provide an apparatus for use in the treatment of fiber cakes wherein provision is made for subjecting the cake to a direct and reverse flow of liquid while also maintaining a progressive flow of liquid endwise of the cake; to provide a novel apparatus for forming and treating a fiber cake; to provide an apparatus wherein provision is made for preventing deforming of a fiber cake during

  • one form of the present invention consists of a rotatable receptacle or bucket I0, the inner peripheral face ll of which is upwardly flared or tapered to conform substantially in size and shape to the outer periphery of the preformed fiber cake l2.
  • these cakes I2 are of annular, truncated shape.
  • the construction, as here shown, is such as to permit the cake l2 to enter the receptacle it so that it assumes a predetermined position with its outer periphery flush with the inner face ll oi the receptacle H1.
  • the inner peripheral face ll of the receptacle ID is provided with a plurality of grooves l3 which extend side by side in curved or inclined relation from the lower portion of the receptacle to a point in close proximity to the mouth or open end of the receptacle In.
  • the direction of the incline or curve of these grooves I3 is in the direction to form a path for liquid expelled or discharged by centrifugal force from the cake I2.
  • these grooves l3 will leave a common plane near the bottom of the receptacle and curve upwardly and circumferentially to the right as seen in Fig.
  • the grooves l 3 to terminate in a plane near the top of the receptacle.
  • the upper or outlet ends of the grooves l 3 not only terminate below the rim of the mouth of the receptacle but in juxtaposed relation to the outer periphery of acake operatively positioned in the receptacle.
  • the function of this construction is to provide a circumferential escape for the liquid discharged from the outer periphery of the cake I2, as otherwise the liquid backing up on this periphery would prevent the necessary leaching from taking place.
  • the grooves I3 have the function of causing the liquid to reenter the cake near the upper end thereof and pass through it in a direction reverse to that caused by the centrifugal action.
  • a hub I4 Coaxially located on the bottom of the receptacle I is a hub I4 which is made fast in any suitable manner to a driven shaft I5 operatively associated with any suitable source of power.
  • annular plate I6 is mounted in the receptacle in spaced relation to the bottom thereof by means of spacer blocks I1 and screws I8 or like fastening devices passing through the bottom of the receptacle and entering the plate I6.
  • the diameter of the plate I6 is such as to fit snugly at its designed location within the receptacle II).
  • a liquid supply pipe I9 is made fast at its lower end in the aperture of the plate I6 and rises coaxially within the receptacle II) to project above the top thereof.
  • This construction provides a passage for entering liquid downwardly through the pipe I9 into the space 20, and then outwardly or radially to the inner wall of the receptacle where, as here shown, it has an escape by way of a. plurality of substantially vertically disposed passages 2I through the plate I 6. That circumferential portion of the plate I6 which is provided with the passages 2I has a width substantially equal to the thickness of the cake 1 2 so that the discharge ends of the passages 2I will be juxtaposed with respect to the bottom annular face of the cake I2 when the latter is in treating position.
  • a cover plate 22 is provided which is apertured to fit over the pipe I9 and seats on a circumferential shoulder 23 formed by the top flange 24 of the receptacle I 0.
  • this cover plate 22 is made fast by screws 25 to a core 26 which fits about the pipe I9 and has its outer surface tapered to conform to the inner surface of the cake I2.
  • The'tapering diameter, however, of this core 26 is such that when the core is in position an annular space 21 will be formed between it and the opposed face of the cake I2 so that treating liquid discharged from the passages 2I will have a relatively restricted channel for flow along that face of the cake.
  • openings or slots 28 are provided through the plate 22 and are so located that their inlet ends are in abutting relation to the upper face of the cake I2. Also it will be noted that these openings or slots 28 are positioned closer to the inner periphery of the cake l2 than to the outer periphery thereof in order not to prematurely release the reverse flow of the treating liquid from the outer side of the cake to the inner side.
  • the rows of openings 28 are radially arranged circumferentially around the plate 22, and preferably the outermost opening of each row is of larger diameter than the innermost opening. This provides for a restricted discharge where there is a maximum volume of flowing liquid so that a larger portion of it is diverted and caused former figures though in this instance its upper circumferential edge is threaded as shown at 33 for the purpose of receiving a fastening ring 35.
  • the cake 35 is fitted with a core 36, after it has been formed in the spinning bucket, and the outer circumference of this core is tapered to conform to the inner periphery of the cake though of slightly less diameter throughout its length in order to have a loose fit within the cake. I'nis loose fit provides for an annular chamber 3! corresponding in function to the chamber 21 in the construction shown in Fig. 1.
  • One end of the core 36 is preferably formed with a flange 38 which serves as a support for the cake when transferringit from the spinning bucket to the processing receptacle 32.
  • This flange 38 is provided with rows of perforations II] which open'at one end against the juxtaposed face of the cake and at the other end communicate with the atmosphere through the aperture of the ring 38.
  • a tubular stem II is provided of a shape and size such as to pass readily through the axial opening ofthe core 36.
  • a flange 42 is provided of such a diameter as to seat against the opposite face of the cake from that with which the flange 38 contacts.
  • Circumferentially disposed about the inner portion of this flange 42 are one or more rows of perforations 43 so arranged as to open against the end of the seated cake 35.
  • the diameter of the flange 42 is also such as to fit snugly within the receptacle 32 and form a false bottom therefor which is supported in spaced relation to the bottom of the receptacle by means of an annular shoulder 44 or any other suitable spacing means.
  • and its flange 42 When the stem 4
  • this extends well through the core 36 in order to form a handle or gripping member 41 by which the cake and its supporting parts can be taken from one place to another.
  • is provided to serve as the initial core or supporting means for the cake 35.
  • the core 36 above described, is somewhat reduced in diameter to allow the sleeve 5
  • is tapered to conform to the tapered opening of the fiber cake but is of somewhat smaller diameter in order to have a loose fit thereon and provide an annular chamber 52 between the cake andthe sleeve through which the treating liquid rises freely to travel along the inner periphery of the cake.
  • with radially disposed holes 53 which are arranged to open against the inner periphery of the cake to serve as passages for a drying medium when the core 36 is removed therefrom.
  • a construction which includes a novel and original device for use as an adjunct of the spinning operation which forms the fiber cake.
  • This device consists of a cup 66 having an annular bottom-6
  • the contour of the cup 60 corresponds generally to the shape which the formed fiber cake is to assume and when the cup 60 is located within the ordinary spinning bucket the fiber filaments are spun directly into it instead of into the bucket as in the usual practice.
  • the upper circumferential edge 64 of the cup is of greater diameter than the correspondingly downwardly tapered edge so that the latter is spaced from the receptacle 62 throughout its length.
  • the lower circumferential edge 65 of the cup 66 is of step formation to conform to the configuration of a stepped ring 66 which is located within and fits about the bottom corner of the receptacle 62. The edge 65 then seats in the ring 66 so that the annular chamber 63 is provided which is closed at its top and bottom.
  • a tubular core 61 is provided of a size to fit loosely within the opening f the cake 60, so that its lower end seats against the flange 6!.
  • This construction provides a passage 68 axially through the core 61 and communicating with the space 16 formed between the bottom 6
  • This loose fit of the core 61 in the cake provides the passage 69 along the inner face of the cake by means of which the entering treating liquid finds a path of least resistance to fiow around the cake and produce the novel surface treatment of the invention.
  • the treating liquid has free access to the lower or bottom face of the cake 35 by means of ports ll arranged circumferentially about the bottom 6
  • the discharge of this liquid from the cake takes place by way of ports 12 formed in the flange 13 of the core 67, it being observed that the flange 73 also serves as a cover for the cup 62 and seats thereon through the medium of a packing ring 14.
  • An annular clamping ring 15 is arranged for threaded engagement with the rim of the receptacle 62 and serves to hold the core 6'! with its fiange 13 in place as well as the cake during the processing operations. While the general direction of flow of the liquid is upwardly and endwise of the cake it is also caused to travel transversely outwardly of the cake due,
  • the wall of the receptacle 62 is preferably provided with relief passages 11 near the upper end of the passage 63 and communicating therewith so that any excess liquid will find an escape by way of these passages I1.
  • the bucket I6 is provided with a plurality of vanes 18 located on the bottom thereof in a circumferential arrangement between the outlet of the liquid supply bore and the circumferentially arranged passages leading to the bottom of the fiber cake.
  • Each of these vanes is of such a shape as to impel the entering liquid radially outward toward the aforesaid passages and thereby increase its velocity so that it enters the passages with a pressure greater than the normal pressure of the liquid travelling downwardly through the bore.
  • the vanes are so arranged that they strike the liquid the moment it emerges from the liquid supply bore and prior to the time it has any flow by centrifugal force, thus exerting a positive impelling force not dependent upon rapid rotation of the bucket.
  • This increased velocity is an important feature of the invention since it makes it possible to obtain the necessary initial velocity with a relatively low rotating speed of the bucket.
  • This low speed of rotation materially reduces the cost of manufacture because parts can be used which ordinarily would not stand the wear and tear of highspeed rotation.
  • the liquid supply bore is of tapered construction with the smaller diameter at the inlet end and the larger diameter at the outlet end.
  • the effect of this taper is to counteract the tendency of the liquid under centrifugal force to back up into the bore and its effect is to produce a reacting force such as will increase the pressure instead of diminishing it as would be the case in a bore of uniform diameter.
  • the cake is completely submerged in a body of liquid moving progressively upwardly and inwardly of the cake toward the discharge outlets to quickly and effectively wash or treat the cake in the desired manner.
  • the grooves in the inner wall of the receptacle serve to relieve back pressure which would otherwise exist at the outer periphery of the cake and this liquid entering the grooves travels upwardly to discharge against the upper portion of the outer face of the cake and flow inwardly across the body to the outlet passages.
