12 Claims. ((31.57-35) This invention relates to the art of twisting yarn and is concerned, more particularly, with an attachment for down twisters by means of which yarn may be impregnated with water or other moistening liquid during the course of the twisting operation.

It has long been the practice in the textile field to pass yarn being twisted through a bath of water or some other liquid that will wet the yarn so that the yarn is in a quite moist condition while the twist is being inserted therein. This has been done in the belief that yarn which is twisted while wet is improved in quality compared to the usual dry-twisted yarn. The presence of the water on the yarn causes the fibers to adhere more closely together, reducing the number of fibers shed from the yarn and resulting in a twisted strand which has improved strength and elasticity.

Various forms of apparatus are known in the prior art for wet twisting yarns. For the most part, they consist merely of a trough or some other elongated container for the moistening liquid mounted on an otherwise conventional twister frame, the yarn being maintained in contact with the liquid contained in the trough by means of a guide roller or red disposed within the trough and under which the yarn is passed. As a refinement, the use of a cover for the trough has been proposed, the cover being provided with appropriate slots to permit the free passage of the yarn.

The wet twisting of yarn on apparatus as just described is not without problems. Twist in appreciable amounts can be inserted in yarn only by two methods: that wherein the supply package is rotated and that wherein the receiving package is rotated. When rotated at moderate to high speed, yarn balloons outwardly under the influence of centrifugal force and is, therefore, in a constant state of agitation or vibration, even when restrained by suit-able guide eyes or pigtails. Since the yarn passes directly through the bath of moistening liquid, the amount of liquid adhering to the yarn is substantially in excess of that which can be easily absorbed. Moreover, the absorbency of the yarn when twisted is substantially less than when untwisted; in other words, liquid is squeezed out of wet yarn when twist is inserted therein. Consequently, there is a substantial surplus of liquid on the yarn while it is in a state of vibration or oscillation, and this surplus liquid is very effectively sprayed or scattered over the surroundings.

It would be prohibitively expensive to construct an entire twister from rustor corrosion-proof materials, such as stainless steel, and it would be both expensive and impractical to provide the machine parts with a protective coating and renew this coating from time to time. Thus, the presence of the surplus liquid on the machine parts causes the information of rust which will eventually destroy the parts and, in addition, increase the likelihood of the yarn becoming soiled during twisting.

Where the twister includes a number of positions arranged side by side as is customary, the volume of surplus water becomes substantial and this surplus water tends to Patented Mar. 10, 1959 acciunulate in pools on the floor of the mill around and beneath the twister where it is diflicult to remove and can also cause damage over long-periods of time, particularly in older mills with wooden floors. Furthermore, the constant spray of liquid is a source of unpleasantness for the operators attending the twister.

It is, therefore, the primary object of the present invention to provide an attachment for a conventional down twister machine, preferably having a number of positions arranged side by side, which attachment immerses a portion of the yarn path completely within a reservoir or container of moistening fluid and removes and collects substantially all of the liquid in excess of that capable of being absorbed by the twisted yarn.

A secondary object of the invention is the provision of an attachment of the type just described which is readily movable from an operative position at which the yarn passes through the moistening liquid to an inoperative position at which the attachment is accessible for purposes of threading-up.

A further object of the invention is to provide a down twister with an attachment having a series of guide rolls for feeding the yarn through a bath of the liquid and a housing for the rolls which permits the yarn to be easily threaded therethrough, but furnishes a high degree of protection for the surorundings from the dispersalv of fluid from the yarn.

Other objects and advantages will be suggested by the following detailed description of the two illustrative ern bodiments of a wetting attachment constructed in accordance with the present invention, when such description is read in conjunction with the accompanying drawings, in which:

Fig. 1 is a left side elevation somewhat in diagrammatic form of a down twister equipped with the attachment of the invention, in which the yarn approaches the twisting zone along an inclined path;

Fig. 2 is an enlarged front elevation of the attachment of Fig. 1, omitting the supply and take-up packages and with certain parts being cut away for purposes of clarity;

Fig. 3 is a right side elevation of thearrangement shown in Fig. 2 with one side of the housing removed to show the interior thereof;

Fig. 4 is a schematic View of the essential parts of the attachment of Fig. 1, showing the operative and in operative positions thereof in solid and dotted lines, respectively;

Fig. 5 is a front elevation similar to Fig. 2 of an alternative embodiment of the invention in which the yarn approaches the twisting zone along the axis thereof; and

Fig. 6 is a view of the alternative embodiment similar to Fig. 3, but with the yarn feed rolls and associated mounting omitted, the inoperative position of the attachment being indicated by dotted lines.

While the improvement of the invention can be adapted to the various down twisters that are commercially available, it is shown, for convenience, in association with a down twister of the type sold under the designation of Model #10 Ring Twister by the Universal Winding Company of Providence, Rhode Island, the essential elements of such a ring twister, omitting supporting or frame members, driving components and the like, being indicated more or less in schematic fashion in Fig. 1. Usually, these twisters are of the gang type, having a multiplicity of positions arranged side by side, each adapted to insert twist in an independent strand of yarn. As these positions are identical, only one need be described for the purposes of illustrating the relationship therewith ofthe attachment. It will be understood, however, that the invention embraces a multi-position twister frame having an attachment for each position.

In Fig. l, a yarn supply package is given the numerical designation 11, the package being supported on a pin 12 which projects in a generally horizontal direction from a fixed portion 13 of the frame of the down twister. A member, which may take the form of guide rod or bar 14, is disposed forwardly of supply package 11 and a strand of yarn Y is withdrawn from the package over and around this guide bar after leaving the package. From the guide bar 14, the yarn passes in a generally downward direction to a feed roll assembly generally designated 16.

As can be best seen in Figs. 2 and 3, feed roll assembly 16 comprises a housing 17 aflixed to an angular bracket 18 forming a part of the framework of the down twister and a pair of feed rolls 19 and 20 mounted in spacedapart relationship on stub shafts projecting laterally of housing 17. Feed roll 19 is substantially larger in diameter than feed roll 20 and has a generally horizontal axis while the axis of the smaller feed roll 20 is slightly inclined upwardly from the horizontal. A drive shaft 22, rotated by means not shown, extends through the rear portion of housing 17 and is in driving engagement with the feed roll shafts by appropriate gearing located internally of the housing and not viewable in the drawings. The feed roll assembly also includes a knock-off arm or lever 23 mounted for rocking movement on the upper front corner of housing 17 and having a counter-balance weight 24 at one end and a yarn contacting roll 25 at the other. The strand of yarn Y is inserted through a guide eye or pigtail 27 projecting upwardly from the top of housing 17, wrapped several turns around both the feed rolls 19 and 20, and then passed over and around the roller 25. Rotation of driving shaft 22 rotates the feed rolls 19 and 20 which advance the yarn by virtue of frictional contact therewith. As long as tension exists in the yarn, the knock-off lever 23 is pivoted downwardly, or counter-clockwise as in Fig. 3, and the thread is advanced. In the absence of tension in the yarn due to thread breakage or the like, the knock-off arm pivots in the opposite direction and through mechanism (not shown) halts the rotation of shaft 22 and, consequently, the advancement of the yarn.

Spaced downwardly from the feed roll assembly 16 is a yarn guide eye or pigtail 28 projiecting forwardly from a fixed part 29 of the twister through which the yarn proceeds before passage to the ring-twisting assembly, generally designated 31. This assembly consists essentially of a yarn package 32 supported on a spindle 33 for rotation therewith, a ring 34 encircling the yarn package and having an upstanding circular track for a traveler (not shown), as is well known in the art, and a ring holder rail 35 for supporting the ring. The ring is lifted or lowered by conventional mechanism to traverse the yarn over the length of the package 32 or such portion of that length as is desired. Rotation of the package 32, of course, inserts twist in the yarn and winds the yarn on the package.

Up to this point, the description has been confined to components ordinarily provided on a down twister machine and these components do not form a part of the present invention, except in combination with the improvements which are about to be described.

Referring again to Fig. 1, there is provided below the feed roll assembly 16, a generally U-shaped trough 40 which may be suspended from the angular frame member 18 by means of an L-shaped hanger 41. down twister is a multi-position machine, the trough preferably extends the full length thereof so that a single trough may serve all of the positions on one side of the machine, and, in this case, the trough may be advantageously reinforced at spaced points along its length by an external rib or flange 42. In operation, the trough Where the erably is water, although any other liquid which will wet the yarn is suitable. Any well known means for automatically maintaining the liquid in the trough at a desired level may be employed if desired.

As can be best seen from Figs. 2 and 3 there is associated with each of the feed roll assemblies 16 a yarn guiding and enclosing unit generally designated 43 which is located on the side of the feed roll assembly adjacent feed rolls 19 and 20. In the embodiment of Figs. 2 and 3 the yarn is caused to pass through a circuitous path having generally the shape of an isosceles triangle standing on one corner and to this end the unit 43 includes three horizontally disposed, cylindrical yarn guiding members 44, 45 and 46, respectively, located at the vertices of the triangle. Guide member 44, forming the lower vertex of the triangle, is located within the interior of trough 40 so that yarn passing there-around is immersed in the fluid contained in the trough; guide member 45, forming the upper vertex, is located at a point spaced somewhat above and slightly forwardly of guide member 44; and guide member 46, forming the final vertex, is located between and forwardly of a plane passing through the axes of the other two with the forward extent of its periphery in approximate alignment with the front edge of trough 40. The particular shape of the respective guide members is capable of some variation, although a particularly satisfactory configuration is indicated in Fig. 2, where the lower guide member 44 has flaring ends, the upper guide member 45 tapers inwardly from both ends towards the center, and the center guide member 46 is of uniform diameter except for a center groove of reduced cross-section. The first of these configurations permits a good deal of latitude in the position of the yarn thereon so that the yarn can freely assume the most favorable position; the second permits some latitude while urging the yarn to a centralized position; and the third centralizes the yarn and keeps lateral vibration to a minimum While the yarn is Within the unit 43. All of the guide members should be formed of a wear-resistant material and a well known ceramic, sold under the trade name Alsimag has been found suitable.

Each of the units 43 includes a housing surrounding and enclosing the guide members 44-46 and a major portion of the triangular yarn path defined thereby, and this housing may be constituted by two side members 49 and 50 formed generally in the same triangular shape as but larger than that of the yarn path. The shape of the side members is not critical and other shapes could be used, provided that they are larger than the dimensions of the path. However, the space required for the housing is at a minimum when the side members have the same shape as the yarn path and a smaller trough can be utilized. For ease in the assembling of the units, all of the guide members are advantageously mounted on the same side member 49, as shown, by means of bolts 51, one for each member, corresponding internally threaded bosses 52 being provided on the exterior of the side member to engage the end of each bolt. The other side member is held in place by means of a knurled nut 53 engaging a bolt 54 projecting from the first frame member through an aperture provided in the other frame member.

The yarn guiding and enclosing unit 43 is disposed slightly to one side of the feed rolls 19 and 20 of feed roll assembly 16 and, consequently, the yarn, if threaded directly from roll 25 to the unit, must approach the latter along a path making an acute angle with a vertical 1 plane through the axes of the yarn guide members 44 and 45. To permit the yarn to enter the unit, the lower front portion of the side member that is adjacent to the feed rolls, i. e., side member 49, is deformed as compared to the other side member. Thus, the lower front portion may be separated from the lower rear portion thereof by a slot 56 and bent inwardly, as at 57, best seen in Fig. 2,

is filled with a supply of a liquid, which may be and pref- 15 or a suitable opening (not shown) may be provided there in. To obtain additional clearance for the yarn, the lower rear portion of the side member 49 may be offset laterally and outwardly, as at 58, from the remainder thereof.

The front and rear walls of the housing are formed integrally with the side members 49 and 50 as flanges projecting inwardly from appropriate edges of the side members. Thus, the front wall 53 projects inwardly from the front edge of side frame member 49, while the back wall 60 projects inwardly from the rear edge of side frame member 50. The association of the front and the rear Walls with particular side members is not essential and, again, may be varied as desired. While the front and rear walls could be of such lateral dimensions as to extend completely between the side members, threading-up is facilitated if their width is selected so that they terminate just short of the opposite side member, leaving a slot between the edges of the walls and the opposite side member through which the thread may be passed. Where such slots are provided, the top and bottom ends of the front and rear walls are preferably inclined upwardly and downwardly, respectively, so as to guide the thread into the slot.

As can be seen from Fig. 3, the yarn emerges from the guiding and enclosing unit 43 on its way to the twisting zone of the down twister through the lower front portion of the unit. In order that the yarn may pass the front wall, flange 59 is cut away in this region. This may be done, for example, by narrowing the width of flange 59, as at 63, and providing a complementary narrow flange 64 in this region only on the opposite side frame member 50. The narrow flanges 63 and 64 preferably terminate at their extreme lower ends within the lateral confines of trough 40 in order that the surplus liquid shaken off of the yarn while in the unit may be directed back into the trough 40. Where the term lateral confines is used in this specification and the appended claims with reference to the fluid-containing trough, it is to be interpreted as that area between a vertical plane extending through the foremost projection of the trough and a vertical plane extending through the rearmost projection of the trough, the longitudinal axis of the trough being considered as extending lengthwise thereof. The term confines" as applied to the trough is used to describe that area limited by the front and rear walls, the end walls, the bottom wall and the upper edges of the front and rear walls of the trough, that is, the area actually within the trough.

It is thought that the threading up of the guiding and enclosing unit and its function in the operation of the down twister will be virtually self-evident from the preceding description. By virtue of the angled top and bottom edges of front and rear walls 59 and 60 and the shape of the guide members 4446, the yarn when merely wrapped around the unit between side walls 49 and 50 is guided automatically into the interior thereof and will be correctly centered on the guide members. In passing under and around the guide member 44, it is immersed in the wetting fluid in trough 4d and an excess of the fluid will adhere to the yarn. Most of this excess will be squeegeed off the yarn in passage over and around guide member 45 and will flow back into the trough. The yarn will normally be in a state of vibration, at least in the last leg of its triangular course, so that more of the surplus liquid will be thrown off and directed back into the trough. As indicated in Fig. 3, in this embodiment of the invention, the yarn leaves the unit 43 and approaches the twisting zone along a path that is slightly inclined with respect to the axis of the ring twisting assembly.

The way in which the guiding and enclosing unit 43 is supported in proper relationship with trough 4t) and feed assembly unit 16 is subject to considerable modification. For example, it will be apparent that the guiding and enclosing unit could be fixedly supported from angularframe member 18. In such an arrangement, how- 6 ever, the presence of trough 40 hampers the insertion of the yarn in and around the unit. For this reason, it is preferred that the unit be mounted for. swinging vertical movement to and from an operative position at which the lower end thereof is positioned within the confines of trough 40 from and to an inoperative position at which the unit is spaced bodily from trough 4th and is readily accessible for threading. To this end, as is best depicted in Figs. 3 and 4, one of the side members, preferably side member 49, as shown, is pivotally attached at. spaced points thereon by means of short bolts to one end. of each of two arms 66 and 67, respectively, the other ends of which are attached for swinging movement to shafts 68 and 69 supported by a bracket 70' fixedly secured to the framework of the twister. The arms 66 and 6'7 may be of angular configuration to clear other operative components of the machine and each other. The lower ex.- tent of unit 43 is determined by means of a stop provided on bracket 70 which is contacted by arm 67, and, to permit precise adjustment of the depth to which the lower end of the unit is immersed within the fluid in tank 40, the stop preferably takes the form of a collar 71 mounted eccentrically on bracket 70 by means of a short bolt 72. A releasable dctent may be employed to temporarily hold the arms in unit 43 in the inoperative upper position and a spring biased button 73 engaging an opening or depression 74 in a tongue 75 projecting upwardly from arm 66 has been found quite satisfactory.

Some workers in the field prefer that the moistened yarn approach the twisting zone along a substantially straight path rather than along a slightly inclined path, as shown in the previously described embodiment, to thereby minimize wear on the yarn in passage through guide 28, and an alternative embodiment of the invention designed with this object in mind is illustrated in Figs. 5 and 6. The discussion of the conventional parts of the down twister will not be repeated in connection with these figures and Where it is necessary to refer to parts which are the same as those shown in the figures illustrating the previous embodiment prime designations will be employed. As before, the liquid with which the yarn is to be moistened is contained in a trough 40' supported from the angular frame member 18' and the yarn Y approaches the wetting attachment over and around the stop motion roller 25'. The alternative embodiment, however, difiers from that previously described in that the guiding and enclosing unit 99 employs only two guide rollers 100 and 101, the former being disposed within the confines of trough 40' and the latter being disposed above and forwardly of the extreme front edge of trough 40-. The yarn, after leaving the stop motion roller 25', passes under and around the lower guide member 100, over and around the upper guide member 101 and down along a straight path aligned with the twisting axis. In so doing, the yarn passes through a circuitous path having generally the shape of a triangle with the upper and lower guide members at two of the vertices of this path. Since the yarn moves straight down from upper guide 101, a third guide is unnecessary. The lower guide member 100 is tapered inwardly from its ends with the point of minimum diameter located closer that end adjacent the feed roll assembly, while the upper guide member 101 is tapered inwardly from its ends toward the center and has a groove atthe center.

The upper and lower guide members and most of the circuitous path of the yarn is enclosed by a housing formed by side members 103 and 104. The guide members are attached to side member 104 by bolts 105 penetrating apertures provided for that purpose in the side member 103 and secured by nuts 106. Both side frame members may be locally depressed as at 107 and 108 to receive the ends of the guide members. The front and rear walls of the housing are formed by flanges projecting inwardly from corresponding edges of the side frame members. Thus, the front wall 110 is constituted by a flange projecting inwardly from the corresponding front edge of said frame member 104, while the back wall 111 is constituted by a flange projecting inwardly of the back edge of side frame member 103. Both flanges terminate just short of the opposite side wall so as to define slots through which the yarn may be passed into the interior of the housing. Also, the top and bottom edges of the front and rear walls are inclined downwardly and upwardly, respectively, as in the preceding embodiment for the same purpose. In the region of the lower front portion of the housing through which the yarn emerges on its way to the twister zone, front wall flange 110 is shortened as at 113 and a complementary short flange 114 is provided on the lower front edge of the opposite side frame member 103. The extreme lower front portion of side frame member 103 is deformed to permit the introduction of the yarn into the housing, as by being properly cut away or bent inwardly as at 115.

The alternative embodiment is so constructed that the guiding and enclosing unit 99 may be detached bodily from its support. For this purpose, the forward ends of two arms 117 and 118 are pivotally attached to a bracket 119 having two spaced apart offset portions 120 and 121. Each of the offset portions has an aperture extending therethrough. One end of each of two bolts 123 is attached to side member 104, the member being held between a small collar 124 fixed to the bolt adjacent the end and a nut 125 threaded on the end. The bolts project inwardly of the side member 104 in a horizontal direction. At the other end of each bolt is a splitspring head 126 projecting exteriorly of side member 103 to an extent fixed by stop collar 127 spaced inwardly of the split head. The split head can collapse sufficiently to pass through the apertures in the offset portions of bracket 119 and expand on the other side to resiliently engage the bracket. Side member 103 can also be removed over the split heads of the bolts.

The rear end of arms 117 and 118 are mounted for swinging movement on shafts 130 and 131 supported from the framework of the machine by a bracket 132. Clearance between the arms and fixed parts can be obtained by forming the arms with slight bends as shown. A spring biased button detent '73 can be used as before to retain the arms and unit in upper inoperative position by engagement with an opening or depression 74' formed in a tongue 75 projecting upwardly from arm 118. A stop to limit the downward movement of the arm and unit may be provided as before.

The operation of the alternative embodiment is generally the same as that of the form originally described. While the unit is temporarily in its elevated inoperative position, the yarn below guide roll 25 can be wrapped vertically around the unit 99 and will be guided there: into by the inclined ends of the front and rear wall flanges. Once inside the unit, the yarn will automatically align itself properly on the guide members 100 and 101, by virtue of their tapering design, as soon as it is placed under tension. As the yarn passes under guide 100, it is immersed in the fluid in trough 40 and an excess of fluid adheres to the yarn as it progresses upwardly to guide member 101. The yarn, of course, is under tension as it slides over and around guide 101 and most of the surface fluid will be rubbed off. Any excess fluid that might be shaken off below guide 101 is intercepted by the walls of the housing and conveyed back to the trough.

It has been found that the attachments described herein function most effectively in removing excess moisture so that the yarn on the receiving package is in condition for use and no further drying steps are necessary.

The terms front, rear, left, right and the like are used herein for convenience only and are obivously relative to the position of the viewer. For this reason, the invention is not to be restricted to the precise relationship called for by these terms. Furthermore, the improvement as a whole is subjectlto modifications in the particular design and engineering details illustrated in connection with the exemplary embodiments.
