Definitions

  • This invention relates to machines for producing artificial threads and more particularly to a guiding mechanism to cause and control the lateral displacement of a thread wrapped one or more times around a wheel and to prevent the thread from riding on itself.
  • the rotary devices used prior to this invention consisted of a simple grooved wheel rotating on an axle. This device was not entirely satisfactory.
  • the thread coming from the coagulafing bath usually had a quantity of coag-, ulating bath liquid adhering thereto.
  • the retation of the device produced a spray of this liquid which was hazardous to the operator. Also, this spray was thrown on the parts of the machine whereby a destructive action was occasioned.
  • the cakes of artificial silk were also coniaminated by the reaction products of the coagulating bath liquor and the metal surfaces.
  • Another object of this invention is to provide a guide mechanism to cause the lateral displacement of a thread wrapped one or more times around a wheel constituting one part of a stretching mechanism and prevent the thread from riding on itself, comprising a roller rotatably mounted and having a smooth uniform body surface, one end of said roller provided with a flange and cooperating with a guard or housing.
  • a further object of this invention is to provide a guide mechanism to cause the lateral dis- 1 placement of a thread wrappedv one or more times around a wheel constituting one part of a stretching mechanism and prevent thethread from riding on itself, comprising a roller rotatably mounted and having a frusto-conical body, the surface of which is smooth, and means to collect the spray and/or drip, together with means to conduct said spray and drip to the coagulating liquor bath.
  • Figure 1 illustrates a front elevation of one modification of a set-up including the'lfeed wheel and the guiding mechanism comprising this invention.
  • Figure 2 is an end view of the set-up illustrated in Figure 1.
  • Figure 3 is a vertical section of one form of roller of the guiding mechanism.
  • Figure 4 is a front elevation of a modified form of a housing or guard.
  • Figure 5 is a front elevation of the housing or guard, the roller being removed.
  • Figure 6 is a modification of the housing on uard illustrated in Figures 1 and 2 together with a roller.
  • Figure 7 diagrammatically iflustrates a set-up employing a plurality of wheels for stretching a thread and guiding mechanisms cooperating with said wheels.
  • the reference numeral 1 designates a wheel which draws the thread 2 from the coagulating bath and constituting one part of a stretching mechanism, provided on one end with a flange 3.
  • This wheel is of the usual type found in bucket spinning machines and is mounted on the frame of the machine in the well-known manner (not shown).
  • the guiding mechanism constituting this invention.
  • This mechanism comprises a roller 4 loosely mounted on an axle 5, so that it may freely rotate.
  • the roller 4 may be made of any suitable material, such as glass, hard rubber, pyroxylin, bakelite, or a similar material. It may be solid or hollow. In the latter case, provision must be made for the mounting on the axle.
  • rollers In the drawings and especially in Figure 3, one form of a roller is illustrated which has given satisfactory results.
  • This roller is provided at one end, which is solid except for a bore 5' through which the roller is mounted on the axle 5, with a flange 6.
  • the other end of the roller is free and the portion adjacent thereto hollow.
  • the body 7 thereof is characterized by a smooth surface.
  • the body is frusto-conical in shape as illustrated in the drawings.
  • the axle 5 on which the roller is disposed is formed of any suitable material, preferably glass, and is rigidly and securedly mounted in a bearing 8 extending from the rear face 9 of the guard or housing 10, the latter being secured in any suitable manner, as by screws 11, to a block 12.
  • the guard 10 is circular in shape and may be provided with a circular boss 13 through which the axle 5 extends.
  • the ribs 14 extending from the face of the boss serve as spray collectors and divert the spray to the grooves 15 formed in the boss 13, and preferably adjacent the ribs 14, whereby free access to the axle by liquid may be had.
  • the housing or guard is formed with a flange 16 in which the flange 6 of the roller loosely fits.
  • the housing may be provided with means, such as a conduit 1'7, which communicates with said housing through the drain 18, whereby the liquid may be returned to the coagulating bath.
  • a gutter 19 may be provided which communicates with the drain.
  • the upper face of the block 12 may be formed with a recess 20 whereby it may receive the drippings from the wheel and post guide 21 hereafter described and feed them back to the coagulating bath.
  • Mounted on the block 12 is a bracket 22 which is formed with a post guide 21 for directing the thread on to the wheel .1 and which may be provided witha sleeve 21", if desired.
  • the post guide 21 may be disposed on the housing as in a bearing 23, as illustrated in Figure 4. Also, if desired, the drippings from the post guide may be conducted to the interior of the housing and thence to the conduit 17. With this in view the housing 10 (see Figure 4) is provided with a drainage passage 24 adjacent the post guide 21 through which the drippings pass to the interior of the housing.
  • the housing may be so constructed that these drippings are caught and conducted back to the coagulating bath and lubricate the axle.
  • Figure 4 one embodiment of such a construction is shown. It comprises a channel 25, formed in the periphery of the housing, communicating with a passage 26 extending to the boss 2'7 in which the axle is mounted. If desired, flanges 28 may be provided adjacent the channel 25 to aid in the catching and directing of the drippings to the passage 26.
  • the use of the post guide 21 depends on the direction which the thread 2 assumes in passing on the wheel 1. Thus, if the direction is substantially that illustrated in Figure 1 by the reference numerals 29 and 30, there is no need for the post guid'eand it may be omitted.
  • the thread 2 As it issues from the coagulating bath, is under tension.
  • the thread passes up behind the said post guide, around the wheel 1 as illustrated in Figures '1 and 2, thence around the roller 4, again around the wheel 1 and down into the funnel 31 from which it is fed into the spinning bucket (not shown).
  • FIG. 6 a guard or housing is illustrated in Figure 6.
  • This housing 10 surrounds approximately one-half the circumference of the flange. In all other respects this housing is similar to that described above. It constitutes a bearing for the axle and is provided with a drain 18 and conduit 17', whereby the spray may be conducted back to the coagulating bath.
  • the guiding mechanism is described in combination with a single wheel. It is, of course, obvious that a plurality of wheels may be used and such an arrangement is used when a stretching of the thread between said wheels is desired. It is to be understood that the disposition of the wheels 32 and 32 relative to each other is not essential to the successful operation of the apparatus.
  • the wheels 32 and 32' may be positioned in line, either horizontally or vertically, or at an angle to each other.
  • Figure '7 there is. illustrated a schematic arrangement of parts wherein a plurality of wheels is used to stretch the thread passing therebetween.
  • the wheels 32 and 32' may be similar in structure to the wheel 1 described above, and the guide mechanisms 33 and 33' similar to the guide mechanism 4 above described.
  • the thread passes on to the wheel 32' as indicated by lines 29 and 30.
  • a post guide there is no necessity for a post guide and it may accordingly be omitted in such a set-up.
  • the stretch of the thread between the wheels 32 and 32 is accomplished by imparting to the wheel 32' a peripheral speed greater than that of the wheel 32. This may be effected, if the wheels are of the same size,
  • smooth surface or equivalent as employed in the description and claims is intended to cover a plain surface which is not groovedand which is neither concave nor ing of the thread on itself, said guide mechanism comprising a roller rotatably mounted and havmg a frusto-conical body with a smooth surface.
