' 1s claims. (ol. 242-43) This invention relates to winding machines and particularly to improvements in -machines for winding packages, cops, cheeses, bobbins and the like of different forms or shapes, for example, packages of either cylindrical or frusta-conical shape and in some cases shaped generally cylindrically or conically with tapered ends.

In the following specication and claims the term package is used in a general sense to apply to any form of wound mass of strand material and the term "yarn is employed to indicate material either of a textile nature or otherwise.

One object of the present invention is to provide means in the winding machine for maintaining the reciprocating thread-guideln close relation to the surface on which ythe winding is performed while preventing it from making contact therewith as it traverses to-and-fro longitudinally thereof.

Another object of the invention is to provide an adjustable bail adapted to bear aga surface of the package and arranged to form a track or guideway for the reciprocating threadguide to maintain the latter in close relation to the package surface without contact therewith.

Another object of the invention is to provide an automatically-adjustable thread-bail adapted to bear against the surface on which the winding is performed and self-adjusting to conform to said surface whether the latter be parallel with or at varying angles with respect to the axis of the package.

Another object of the invention is to provide a winding mechanism with a reciprocating thread: guide having an oscillating motion in addition to its reciprocation and provided with an elongate thread-slot in which the yarn plays back and forth to distribute the wearon the guide.

Another object of the invention is to provide a Winding machine having the features herelnbefore mentioned and adapted for winding relatively soft packages of various forms or shapes with greater precision and having improved stability over those previously produced on mav chines of the present type.

Further objects of the improvement are set forth in the following specication which describes a preferred form of construction of the invention, by way of example, as illustrated by the accompanying drawings. In the drawings:

Fig. 1 is an end elevational View of `a winding machine of conventional type embodying the improvements of the present invention;

Fig. 2 is a partial side elevation of the same lshowing the winding spindle, traverse-frame,l reciprocable thread-guide and other essentia1 elements of the machine; y

Fig. 3 is a fragmentary view of the winding spindle and traverse-frame viewed in the direc- Fig. 5 is a similar plan view showing a-cylindri cal form of Winding mandrel with the4 threadbail adjusted to cooperate therewith.. y

Referring particularly to Figs. 1 and 2, the winding machine herein illustrated is generally of well-known constructionas comprising a main frame 2, a rotary Winding spindle 3 journaledin bearings at the top of the frame, and a camshaft 4 arranged parallel with the spindle and journaled in bearings on the lower part of the frame. A swinging traverse-frame 5 of conventional form having a main horizontalportion 6 with depending legs, one of which is shown and designated l, is pivoted on the cam-shaft 4. The traverse-frame 5 supports the reciprocable thread-guide I0, to be later described, to adapt the latter to move outwardly away from the winding spindle 3 during the growth in diameter of the package. The traverse-frame 5 is balanced by a counterweight kII depending below its pivotal axis and its swinging movement is controlled by a dog I2 of usual construction arranged with its upper portion sliding in a tapered groove in an arcuate quadrant I4 attached to the main frame 2 by a' stud I5. A finger-lever I3, shown fragmentarily in Fig. 4, provides means for releasing the' dog I2 from th quadrant I4 to permit manual adjustment of the traverse-frame 5 toward the winding spindle 3 at the start of a winding operation. ,c

The quadrant I4 is pivoted on the stud I`5-qand provided with an upstanding portion I6 formed with a detent-shoulder I1 adapted to interengage parts not herein shown and described 1n detailv as they may be of any usual form as well known to those versed in the present art.

'Ihe starting lever 23 also carries a rearwardlyextending arm 22 mounting a brake-shoe 23 adapted to engage with the tapered periphery of a brake-disk 24 fast on the spindle 3, see Fig. 2. Suflice it to state herein that by rocking the starting lever or handle 20 in a clockwise direction as viewed in Fig. 1 the clutch is engaged to apply power to rotate thespindle 3 which is suitablyconnected to drivethe cam-shaft 4; and during this application of the drive the detent-abutment I8 on the arm I9 of the lever 20 is engaged with the detent-shoulder I1 on the quadrant I4 to maintain the machine operative. To arrest the operation of4 the machine the quadrant I4 is rocked'upwardly on its pivot l to release the detents whereby a spring or other means, not shown, will throw the lever 20 to declutch the drive. The quadrant I4 may be rocked automatically when the yarn breaks or its supply is exhausted by means of a'dropwire or stopping lever 26 pivoted to the end `of the quadrant at 21 with its end adapted to engage the teeth on a rotating wheel or disk 23 when the lever is released from the yarn. The quadrant `I4 may be rocked automatically upon completion of the package by the engagement of a shoulder 29 on the traverse-frame 5 with the beveled face 30 of a block or stopmember 3| which is adjustable along the quadrant to determine the size of the package.

The horizontal portion 5 of the traverse-frame 5 is provided with a grooved guideway 32 which receives a reciprocable traverse-rod 35 carrying the thread-guide i0. The inner end of the traverse-rod 35 is attached to a crosshead 36 carrying a roller or bowl 31 which engages in a helical groove in a traverse-cam 40, shown fragmentarily in Fig. 2. The cam 40 is of usual construction having a cylindrical rim supported from a hub 4I mounted fast on the cam-shaft 4 to be rotated thereby.

The traverse-rod 35 is retained in the groove 32 of the traverse-frame 5 by an overlying portion of the traverse-frame back 43 which is made separate from and attached to the frame by screws 44 in accordance with the usual construction. 'Ihe traverse-frame back 43 extends parallel with the axis of the winding spindle and at its upper end it is formed with a forwardlyprojecting portion or lip 45 having a vertical face on its forward side with a sharply beveled edge extending rearwardly from the top thereof. It is noted here that in the standard form of construction of the present type of machine the traverse-frame back 43 is made removable from the main traverse-frame 5 in order that backs of different form may be substituted therefor in accordance with the shape of the package to be wound on the machine. That is to say, when parallel-sided or cylindrical packages are wound on the machine a traverse-frame back having a forward guiding face disposed parallel with the axis of the winding spindle is attached to the traverse-frame 5; whereas, when a package of frusto-conical shape is to be wound a substitute traverse-frame back with an inclined guiding face must be employed. A suitable tension-device is usually provided as an adjunct to the machine to apply tension to the strand of yarn y feeding from its source of supply to the Winding spindle 3. As so far described the Winding machine is similar to those now generally used in the art.

The traverse-mechanism of the present machine as herein shown is adapted to wind packor straight with one end only beveled or it may take other similar shapes. To provide for winding this type of package the traverse of the reciprocating thread-guide l0 must be progressively shortened during the winding at. one or both ends of the package and this may be efiected by giving the guide an oscillating motion in addition to its reciprocatory movement. The means herein shown for oscillating the threadguide at the ends of its traverse are similar to those illustrated and described in a zo-pending patent .appncaugm serial No. 734,824, med by Hill and Seem July 12, 1934, now Patent No. 2,154,847 issued April 18, 1939.

In the present form of construction the threadguide l0 consists of a relatively narrow blade having a hinge-like bearing 43 at its lower end pivoted on a-'pin 50 which is held in bearings 5l formed as a part of a sheet-metal member 52 carried by the traverse-rod 35. The member` 52, in turn, is pivoted on a stud 53 riveted to an upright member or blade 55 secured fast at its lower end to the traverse-rod 35. The lower end ot the blade 55 is received in a slot in the traverse-rod 35 and held inplace by aset-screw 55. The blade 55 extends upwardly and is oiset at the top with its upper end bearing against the forward face of the lip 43 on the traverse-frame back 43. A lug or extension 51 on the upper end of the blade 55 is bent across the edge o! the lip 45 in engagement with its beveled face whereof to form a sliding connection between thel blade and the traverse-frame back 43. It will thus be observed that the thread-guide III is arranged to rock on its pivot-pin 50 to move toward and away from the traverse-frame back 43; and likewiseit is adapted to oscillate laterally with the member 52 pivoting on the stud 53 which connects said member to the blade 55. The rocking motion of the thread-guide I0 toward and away from the traverse-frame back 43 adapts the guide to follow the tapered contour of a conical package, the path of movement of the guide being controlled by a thread-bail 60 which forms one feature of the present invention.

The bail 50 is of bifurcated form, being conveniently constructed of wire rod having its ends bent at an angle to its main portion to form legs 62 and 53. As shown in Figs. 4 and 5, the ends of the legs 52 and 53 are inserted in holes in the upstanding ends of a rockable U-shaped crossarm or bar 55 which is pivotally mounted on the upper part of the traverse-frame back 43. Suita-ble set-screws B6 at the ends of the bar 65 engage against the ends of the legs 62 and 53 of .the bail 60 to secure the latter in adjusted relation rto the bar, thus making it possible to change the position of the ball with respect to the -bar in accordance with the shape of the package being wound. The rockable bar or crossarm 55 is formed at its center with a bore 61 through which is riveted the upper reduced end of a pivot-pin or stud 58. The stud 58 has enlarged bearing bosses 69 journaled in a pair of spaced bearings 'l0 and 1I projecting from the rearward face of the traverse-frame back 43. To prevent too free turning movement of the bar 65 a relatively flat leaf-spring 13 is secured to the traverse-frame back 43 by a screw 14 with its free end extending between the bearings 15 and 1I and engaging frictionally against the central reduced portion of the stud 58. Fastened to the rearward face of the traverse-frame back 43 is a thread-guiding member 15 formed of sheetmetal with legs 15 at either end clamped to the traverse-frame back by screws 11. The upper portion of the member 15 is rolled over in an extended loop 18 forming a pathway for the strand of yarn y drawing thereacross as it feeds to the thread-guide I5. The thread-guide I5 is formed with an elongate slot 85 through which the strand y feeds from across the top of the'threadguiding member 15, the slot 85 having a flaring re-entrant opening to facilitate the threading of the yarn therein'to.

It will -be noted by reference to Fig. 1 of the drawings that the thread-guide I5 normally bears against the straight portion of the threadbail 55 which, as before stated, directs the course of its reciprocation and at the same Itime restrains it from contacting with the surface of the package on which the winding is being performed. In order to maintain the guide I5 in this relation to the thread-ball 55 while adapting it to travel therealong, a helical spring 8|, shown most clearly in Figs. l and 4, tends to urge the guide outwardly away from the traverse-frame back 43. The spring 8| is coiled about a pin 82 projecting from an arm 83 formed as part of the member 52, the end of the pin also engaging through a slot 84 at the end of an arm 85 proliecting laterally from the thread-guide I5, see Fig. 3. The spring 8| is tensioned between the arm 85 and a ange 85 on the pin 82. The pin 82 is secured fast in the arm 83 of the member 52 and projects therethrough to forma bearing or pintle for a roller 95, see Fig. l.

The roller 95 is arranged to travel in the slot 9| of a guideway or track 92 which is pivoted to the forward face of the traverse-frame back 43 by a screw 93 as shown in Fig. 3. The track 92 a'cts through the roller 95 to control the position of the thread-guide I5 during the latters reciprocation, whereby the extent of its traverse may be varied by changing the position of the so that the package is built up with layers of gradually decreasing length to form the tapered ends oi.' the package.

The essentialelements of the winding machine having been described in detail its method of operation is explained as follows: A suitable paper tube or other yarn-carrier T is placed upon the mandrel carried by 'the winding spindle 3 and the strand of yarn y led up from its source of supply, not herein shown, through the tension-device and passed over the thread-guiding member 15. From the curved surface of the member 15 the yarn is drawn. forward through .the slot 85 in the thread-guide fl5, thence down across the threadbail 55 and its end attachedI to the tube or yarncarrier T. Figs. 1 to 4 of the drawings villustrate the yarn-carrier-T on which the winding is to be performed as of conical shape to receive a. similarly-shaped package and in the arrangement of the machine as shown the package is built up with tapered ends. For this type of winding the thread-bail 55 is initially adjusted on thecrossarm 55 to aline its straight portion with' the surface of the tube or carrier T, the outer end of the bail being spaced ata greater distance from the end of the cross-arm than its ixmer end. This adjustment is necessary only for winding sharply tapered packages as ordinarily the rocking motion of the cross-arm or bar 55 willl adapt the -bail 55 to a slightly inclined surface, but as the rocking of the cross-arm is limited somewhat by its outer ends striking against 'the traverse-frame back 43 it has been considered preferable to provide for the adjustment noted.

After the bail 55 has been properly adjusted with respect to the cross-arm 55 the traverseframe 5 is moved into position to cause the bail to bear against the surface of the yarn-carrier T, this being accomplished by releasing the dog I2 the starting lever 25 to' the right as viewedin by a bolt 91. The bolt 91 projects through a slot plate may be adjusted to vary the relationship of its cam-slot 95. It will be understood that as the traverse-frame 5 swings outwardly with the 'thread-guide I5 receding from the winding spindle 3 as the package increases in diameter the projection 94 will slide down the incline of the camslot 95, thereby tilting the track 92 to raise its outer end above the horizontal. 'Ihis Itilting of the track 92 causes the thread-guide I5 to be gradually rocked inwardly away from the ends of its traverse as the roller 95 slides in the slot or guideway 9| of the track. In this way the extent of traverse of the thread-guide I5 is gradually lessened by the oscillating movement of the guide with relation to the traverse-rod 35 75 Fig. ,1. thereby engaging the detent-abutment I8 on its arm I9 with the detent-shoulder I1 on th'e extension I5 of the quadrant I4. During this movement of thegstarting lever 25 the brake 23 is released from the brake-disk 24 and the clutch or other drive-connecting means is actuatedl to apply power to the winding spindle 3 and camshaft 4. As the spindle 3 is rotated in clockwise directionas viewed in Fig. 1 the yarn y iswound onto the tube or carrier T and traversed longitudinally thereof by the reciprocating movement of the thread-guide I5 which is connected through the traverse-rod 35 to the helical cam 45. During its reclprocation the thread-guide I5 slides along-the thread-bail 55 and due to the inclination of the bail with respect to the axis of the winding spindle the guide is caused to rock back and forth about its pivot 55, being maintained constantly bearing against the bail by the spring 8|. The bail 55 'thus causes the guide I5 to follow the inclinedl surface of the winding without contact therewith, thus avoiding any abrading action of the-guide on the yarny face of the winding, forcesv the upper portion of the traverse-frame 5 outwardly away from the axis of the winding spindle 3. At the same time the counter-weight H causes the traverse-frame 5 to maintain the thread-bail 60 constantly bearing against the surface of the yarn wound onto the carrier T. Since the pressure of the package on the bail 60 which forces the thread-guide I3 and its support or traverse-frame '5 outwardly is distributed across the full length of the package there is less tendency to crush the yarn mass and consequently softer packages may be produced. Soft-Wound packages are desirable for various purposes such as for dyeing or otherwise treating the yarn with iluids where a porous mass is of advantage; and also to prevent the crushing or matting of yarns of a soft-or lofty nature.

At the start ofthe winding operation the camtrack 92 assumes a position with its slot 9| substantially parallel with the traverse-rod 35 so that as the thread-guide I is reciprocated with the traverse-rod the roller 90 on its arm35 will have no effect to oscillate the guide. As the traverse-frame recedes from the axis of the winding spindle during the increase in diameter of the winding the projection or follower 94 at the end of the cam-track 92 slides down the incline of the cam-slot 95, thereby causing the track to be rocked on its pivot-screw 93 to incline its outer end upwardly. Consequently, each time the traverse-bar 35 is reciprocated in either direction the thread-guide l0 will be rocked inwardly away from the end of its traverse, its pivotal connection at 53 with the blade 55 providing for this oscillating motion. In this manner as the inclination of the track 92 is increased the oscillating motion of the thread-guide I0 is augmented so that the length of traverse of the guide is gradually and progressively shortened. This results in gradually shortening Vthe length of the layers of yarn deposited on the carrier T so that the package is built up with tapering ends as indicated by the dash lines in Figs. 2 and 3. The winding operation continues until the package reaches its predetermined diameter, whereupon the. operation of the machine is arrested automatically by the engagement of the shoulder 29 on `the traverse-frame 5 with the beveled face 30 of the sizing block 3l. 'I'his engagement rocks the quadrant I4 upwardly to rel lease its detent shoulder I1 from the abutment I8 on the starting lever 20, whereupon the latter is actuated by the spring, not herein. shown, to declutch the drive.

When it is desired to wind cylindrical or parallel-sided packages on the machine the threadbail 60 may be adjusted in substantially parallel relation to the rockable cross-arm 0r bar 65 as shown in Fig. 5. With this adjustment of the thread-bail the winding proceeds in the manner explained previously with the thread-guide I0 sliding along the straight portion of the bail 60 to restrain it from contacting with the surface of the winding, the bail acting as explained above to force the traverse-frame 5 outwardly away from the axis of the winding spindle as the package increases in diameter. In either case the pivotal mounting of the cross-arm or bar 65 prolvides for a rocking motion thereof so that the thread-bail may accommodate itself more precisely to the surface of the package. In other words, if the periphery of the package changes in shape, as is sometimes desired to form cones with an increasing taper, the cross-arm 65 will rock to adjust the bail to this change in angularity of the surface on 'which the winding is being performed. The thread-bail 60 will thus be maintained bearing against the surface of the package being wound throughout the whole extent of the latter so that the pressure against the winding will be distributed over a relatively greater length of contact than where previously the guide has been arranged to bear against the package and to force the traverse-frame outwardlyaway from the axis of the winding spindle. The present arrangement of the thread-bail is therefore of advantage in winding soft packages and constitutes an improvement in the art v as preventing undue pressure of the guide on the package tending to rcause its collapse and also as eliminating frictional rubbing action of the guide on the yarn which with fine materials would have a deleterious effect.

It has also been determined in practice that the arrangement of the bail to adapt it to bear against the surface of the package being wound with the thread-guide spaced at a slight distance from this surface has another advantageous result as tending to produce more perfectly-shaped packages having greater stability at their ends. As the thread-guide I0 approaches the' end of its traverse it has a tendency to whip or flutter due to play in the parts arising from clearances or as caused by wear. 'I'his fluttering action of the guide resulting from momentum and inertia of the parts causes the yarn to be whipped outwardly so that it may overrun the end of .the package to cause loose loops termed stitches or cobwebs on the ends of the package. With the present form of construction and method of operation of the thread-guide the short length of yarn between the guide and the face of the package,v that is the length extending across the bail 60, absorbs the false motion of the guide, thereby preventing the yarn from whipping out across the end of the package to cause irregularities and defects in the winding.

As another feature of improvement in the present invention it will be noted that since the thread-guide I0 oseillates back and forth during its reciprocation from one end of the package to the other the yarn y will ride up and down in its elongate slot as the strand is maintained at a constant height by the threadbail 60. Due to this sliding action of the yarn in the slot 80 of the thread-guide I0 the wear is distributed along the sides of the slot and consequently is prevented from cutting grooves in the guide as sometimes occur with hard materials such as silk and glazed yarns.

It will be observed from the foregoing that the present invention provides important improvements in the winding art which make for precise winding and result in a better product, the wound packages being of accurate shape and more stable in structure. While the invention is herein illustrated and described as embodied in a preferred form of construction, it is to be understood that various modications may be made in the structure and arrangement of the parts of the machine without departing from the spirit or scope of the invention.
