SON, OF CBANSTON, RHODE ISLAND, ASSIGNOB TO UNIVERSAL WIND- ING COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS forms of packages of thread, yarn, cord or V sectional on line 22 of Fig. 1, looking in the WINDING MACHINE Application filed July 21,

This invention relates to winding machines for winding cops, cones, cheeses and other other strand material, hereinafter referred to generally by the term yarn; and particularly to drum winders wherein the package is rotated by contact with a drive-roll or drum. I

Specifically,the invention consists in a rib bon-breaker, so-called, which operates to control the disposition of the turns of winding on the surface of the package to prevent the formation of bands or ribbons in which the yarn coils are crowded together or piled.

One object of the invention is to provide a device for the purpose specified which will be the invention, by way of example, as illussimple and compact in construction and efficient and reliable in operation.

Another object of-the invention is to provide a clutch-mechanismincorporated in the driving-means of the winding machine and operating to disrupt the synchrony of motion between the package and the traverse-means which deposits the coils of winding in place thereon.

Another object ofthe invention is to provide a mechanism of the type specified for periodically decelerating the rate of movement of one or the other of the cooperating winding elements, either the package-rotating means or the yarn-traversing means, at recurring'cycles throughout .the winding.

Another object of the invention is to provide automatically operated means in the driving-mechanism for intermittently disconnecting one of the windingelements from the drive to effect intermittent deceleration in the speed thereof.

Further objects of the improvement are set forth in the following specification which describes a preferred form of construction of trated by the accompanying drawings. In the drawings:

The present invention relates particularly to means for. imparting an alternately retarded and accelerated rate of motion to one of the cooperative elements of a winding machine, either the rotatable yarn-receiver on which the package is wound or the means which traverses the yarn longitudinally thereof, and in general consists in an automatically actuated clutch incorporated in the drivingmachine herein illustrated by way of examplc is of the double gang type comprising a plurality of winding'units arranged in series along the sides of a horizontal frame or bed 12. The bed 12 is supported from suitable legs 13 and at one end is mounted an electric motor 15 carried on a base 16 which is adjustable with respect to the bed. Spaced along the? top of the bed 12 are a series of brackets 01 standards 17 which support bearings for a drive-shaft and other parts of the winding-mechanism, two opposite units bethe package wound on the cop-tube. In this form of construction the usual reciprocating thread-guide is dispensed with and the driveroll 19 has its peripheral surface provided with connected helical grooves 20 and 21 extending in opposite directions and adapted to receive the strand of yarn y to guide it back and forth between the ends of the package. This particular form of traversing-means is fully shown and described in United States Letters Patent No. 1,749,355 dated March 4,

1930. It is to be understood, however, that the present ribbon-breaker is adapted for use on winding machines of other types, such as those wherein the package is driven by contact with a drive-roll and the yarn traversed by means of a reciprocating or oscillating guide, or with any other form of drumdriven winder.

- In the form of construction shown in Figs. 1 and 2 the drive-roll 19 is secured on and rotated by a horizontal shaft 22 journaled in ball-bearings supported by the brackets 17. Coaxial with the shaft 22 is a driveshaft 36.-driven from the motor 15 through a train of gearing to be later described. The shaft 22 extends throughout the whole length of the gang machine and carries a plurality of drive-rolls for any desired number of winding units. The present machine is shown as adapted for winding packages of conical form in which the yarn body is built up on any suitable support or receiver, such, for example, as thecone-tube C which may be of wood or fiber'and mounted to rotate on the winding-spindle or mandrel 18. As shown most clearly in Fig. 2, the winding spindle 18 is pivotally mounted at the forked end of an arm 25 which is hinged on a rod or stud 26 held in a bearing 27 projecting from the top of the bracket 17, this construction being common to machines of the present type. The arm 25 is usually weighted to cause the surface of the yarnreoeiver C, or of the package, to be held firmly in contact with-the periphery of the drive-roll 19 and as the yarn is built up on the receiver it forces the latter upwardly with the arm 25 pivoting on its stud 26. 1 o

The power means for the whole series of winding units is connected to drive the shaft 22 through suitable gearing preferably arranged as next described. Referring to Figs.

' 1 and 4 of the drawings, the armature-shaft 28 of the motor 15 carries an element 29 keyed thereto, one end of which is formed or collar 43 is disposed on the reduced end 38 of the shaft 36 for taking the end thrust of the ball-bearing 39. A pinion 44 is keyed to the reduced end 38 of the shaft 36 abutting the end of the sleeve 43, being provided with a hub or boss 46 projecting from its opposite side. Abutting the end of the hub 46 is a ball-bearing 47 which is supported on the reduced portion 38 of the shaft 36 to provide a journal for a ring-gear 48 having an annular recess 49 for receiving the bearing. A larger ring-gear 51 is mounted on the shaft 38 coaxially with the ring-gear 48 and secured rotatively therewith by means of a plurality of pins 52 engaging suitable recesses 53 in the abutting faces of the gears. The larger gear 51 is journaled on a ballbearing 54 disposed in an annular recess 56 in its side and supported from the shaft 36. A nut 59 screwed onto the reduced threaded end 58 of the shaft 36 abuttin a washer 57 holds the several bearings an the gears 48 and 51 in place on the reduced portion 38 of the shaft 36.

Keyed to the shaft 36 abutting the side of the bearing 37 is a clutch-plate or disk 61 formed with a friction face 62 recessed in its side. On the opposite side of the clutch-disk 61 from the bearing 37 is a similar ball-bearing 63 supported from the shaft 36.

The shaft 22, as beforeexplained, is journaled in ball-bearings mounted on the brackets 17 and extends coaxially with the shaft 36. The end of the shaft 22 adjacent the end of the drive-shaft 36 is provided with an en'- larged portion 69 which, in effect, forms a' continuation thereof. A clutch hub 71 surrounds the enlarged portion 69 of the shaft 22, being keyed or otherwise suitablysecured thereon against longitudinal or rotative movement with respect thereto. Conveniently, a keyway 72 formed in the bore of the hub 71 is engaged by a key 73 fast in a spline in the shaft. An annular recess 74 formed in the end of the hub 71 receives the outer washer 82 of leather, asbestos, composition or other material having a high coeflicient of friction. On the opposite side from the lining 82 the clutch-plate 79 is formed with'an over- 5 hanging 'flange 86. I

' The hub'71 is exteriorly threaded at'87 to receive the interiorly threaded hub 89 of a spider-member 88 which is thus mounted for adjustment longitudinally of the collar. The spider 88 is provided with pairs of opposite lugs 91 projecting radially therefrom at points spaced equidistantly' around its circumference, extending through holes in the lugs; 91 are 5 dogs 93 which serve as the meansfor sliding the clutch-member 79 toward the plate 61.

The dogs 93 are formed with upstanding ears 94 arranged with their forward flat faces adapted to engage against the lateral edge of the rim 86 on the clutch-member 79 to force the latter into engagement with the clutch-plate 61: Thedogs have rearwardlyprojecting arms 96 through which they are rocked from a slidable clutch-ring 97.

5 The clutch-ring 97 has a projecting hub portion 98 and is slidably mounted on the enlarged shaft-portion 69, being preferably held rotatively therewith by the key 73 previously referred to. An annular groove 99 is 0 formed in the side of the clutch-ring 97 adjacent the spider 88, the sides of the groove being inclined at an angle to'the axis of the ring or of frusto-conical form in cross-section.

ceive-d within the groove 99 engaging the inner conical face thereof whereby the sliding of the clutch-member 97 serves to rock the dogs in the manner and for the purpose as later explained. The hub portion 98 of the 0 clutch-ring 97 is formed with a radially projecting annular flange 100, upon which is rotatively mounted an interiorly grooved collar 101. 4

The collar 101 isconstructed in two complementalp'arts bolted together, at 102, see Fig. 5. At diametrically opposite points on its sides the collar 101 is provided with radially projecting studs or trunnions 103 for engagement with a forked shipper-arm or lever. 108 by means of which the collar, and thereby the clutch-ring 97 may he slid along the enlarged portion 69 of the shaft 22. The shipper-arm or lever 108 is pivoted to a bearing 107 supported on a curved arm 104 reaching up from one of the brackets 17. Referring to Fig. 5, the upper extremity" of the arm 104 p is bifurcated and provided with a pair of axially alined bosses 105. The shipper-lever 108 is formed with a hub 106 pivoted on a stud 109 passing through holes in the opposite bosses 105. Below the hub 105 the shipperlever 108 is. shaped as afork, having a pair of downwardly extending arms lllstraddling the sides of the collar 101. The ends of the arms 111 are slotted at 112 to receive see Fig. 5. Pivoted on pins 92* The ends of the arms 96 of the dogs 93 are rethe studs 103 projecting from the'sides of the collar 101. The forward arm 111 of the shipper-lever 108 is continued downwardly in an extension 113 carrying a roll or (:am-

Fig. 1. As herein illustrated, the bearings 121 and 122 are formed in depending extensions of the brackets 17, while the bearings 123 and- 124 are constructed integral with the bed 12. As shown in Fig. 1, the'ring-gear 48, which is free to rotate on the reduced portion 38 of the shaft 36, see Fig. 6, meshes with a gear 126 keyed at 127 to a stud-shaft 128 in the manner illustrated in Fig. 7. The stud-shaft 128 is journaled in ball-bearings 129 held in the opposite counterbored ends of a cylindrical casing QIjOlll'Dfil-bOX 130 which ismounted in a circular orifice 131 in the standard 33 of the frame and fastened in place by means of screws'132. Constructed integral with the stud-shaft 128 is a pinion 1 33 arranged to mesh with a gear 134 which is keyed to the end of the cam-shaft 119 at 135 and secured thereto by means of asetscrew 136.

The armature-shaft 28 of the motor 15 'drivesthe train of gearing last described through its gear 31 meshing with the larger r ng-gear 51 which is fast with the small ring-gear 48 meshing with the gear 126. Through this arrangement of the gearing the cam-shaft 119 is driven from the motor 15 at a greatly reduced rate of speed. Y

The cam 137, previously referred to, is of cylindrical form and secured fast on the camshaft 119 in position to engage with the roll;

or follower v117 on the shipper-lever 108. The cam 137 may be secured to the shaft 119 by means of a set-screw 138, as shown in Fig. 1, and is provided with a peripheral groove 139 in which the cam follower 117 travels. The groove 139 consists of two circumferential straight portions arranged 'in spaced parallel relationship and connected by inclined portions 140. As the roller 117 is engaged with the inclined portions 140 of the cam-groove 139 the shipper-lever 108 will be rocked in one direction or the other, but with the follower traveling in the straight portions of the groove the lever will have a dwell.

Referring to Fig. 8 of the drawings, the v hub 89 of the spider-member 88 is formed with a pocket 141 at the inner end of which is a smaller bore 142. The outer end of the pocket 141 is closed by 'a plug 143 having a bore corresponding .to the bore 142. ,Aipin 144 formed with an enlarged boss 145 is slidably mounted in the bore 141 with one end projecting through the bore 142 audits opposite end through the plug 143. A spring 146 coiled about the pin 144 is confined in the pocket 142 by the plug 143 and bears against the boss 145 to urge the pin toward the right as viewed in Fig. 8. The rearward end of the'pin 144 has a knurled head 147 by means of which it may be withdrawn against the pressure of the spring 146. The opposite or forward end of the pin 144 is adapted to engage in one of a plurality of equally spaced holes 149 formed in .the clutch-member 79. It will be understood that the spider-member 88 and the c1utchmember 79 rotate as a unit when the pin 144 is engaged with one of the holes 149. To adjust the position of the spider-member 88 axially with respect to the clutch-member 79 the pin 144 is withdrawn. to permit the spider to be turned on thethreaded periphery of the hub 71.

I n explaining the operation of the machine the shaft 36 will be referred to for convenience as the drive-shaft, and the shaft 22 having'the enlargement 69 will be referred to as the driven shaft. Referring to Figs. 1 and 4, the gear32 on the motor shaft 28 meshes with the gear 44 keyed to the drive- .shaft 36 In the preferred arrangement herein illustrated the gears 32 and 44 are of the same; size and the drive-shaft 36 will therefore be driven at the same speed as the motor. The drive-shaft 36 rotates the clutch-plate 61 keyed thereto and the drivenshaft 22 is rotated at the same rate of speed as the drive-shaft when the clutch is engaged.

To obtain the differential ratio of speed between the shaft 36 and shaft 22 for the purpose specified, the clutch-member 79 is moved intermittently into and out of engagement with the clutch-plate 61 through the action of the shipper-lever 108. The shipper-lever 108 is operated from the cam 137 in the manner as next explained. As shown in Fig. 1, the cam-roll 117 on the shipper-lever 108 is traveling in the lefthand straight portion of the cam-groove 139 whereby the clutch-member 79 is held engaged with the, clutch-plate 61 so that the drive-shaft 36-and driven-shaft 22 rotate as one. lVith the parts in this re ationship the clutch-ring 97 is maintained in position withdrawn from the spider 88 so that the inner conical face ofthe groove 99 acts to .force the arms 96 of the dogs 93 radially outward to cause themto hold the clutch member 79in frictional engagement with the clutch-plate 61.

.In practice it has been found that satisfactory winding is accomplished on the machine when the clutch-member 79 is engaged in'driving connection .with .the clutch-plate 61 approximately two-thirds of the time. Accordingly, the left-hand straight portion of the cam-groove 139 extends throughout two-thirds'of the circumference of the cam 137 and the remaining portions of the groove one-third of the circumference of the cam. As the cam 137 is continuously rotated the follower or roll 117 is periodically caused to ride through the angular portion 140 of the groove 139 into the right-hand straight portion. Under this action the shipper-lever 108 is rocked to the right, as shown in Fig. 4, and the clutch-ring 97 is thereby advanced to the right. As the clutch-ring 97 slides to the right the arms 96 of the dogs 93 are withdrawn radially inward. The pressure of the dogs 93 on the rim 86 of the clutchmember 79 is thus relieved so that the fric- 82 and the face of the clutch-plate 61 is released. The speed of the driven-shaft 22 c is therefore immediately reduceddue to the effect of inertia and the resistance'to rotation of the various elements carried on the shaft. The release of the driving connection between the shaft 36 and shaft 22 is for a brief interval only, and as the cam 137 continues to rotate the follower 117 on the shipper-lever 108 is again carried back into the-left-hand portion of the cam-groove 139 to shift the lever-to reengage the clutchmember 79 with the clutch-plate 61. The speed of rotation-of the shaft 22 is then accelerated until it reaches normal and'in this way an intermittent retardation in the speed of one of the operating elements of. the machine is efiected.

\Vear on the clutch-lining82 may be compensated for by withdrawing the end of the pin 144 from the hole 149 in the clutch-member 79 and turning the spider-member 88 on its threaded hub 71 to adjust it toward the clutch-plate 61. The pin 144 is then engaged with another hole 149 of the series provided to lock the spider-member 88 fast with its hub 71.

The method of operation of the complete machine and the functioning of the ribbon breaker in connection therewith areas next explained. Referring to Figs. 1 and 2 of the drawings, the machine is prepared for winding by placing a wooden or fiber conetube or yarn-receiver C on the spindle 18. In applying the yarn-receiver C the arm 25 is raised and the spindle 18 swung outwardly on its swiveled joint at the end of the arm in accordance with the well-known practice with winding machines of the present type. After the yarn receiver C is in place the spindle 18 is swung back into parallel relation with respect to the axis of the drive-roll 19 and the arm 25 is then lowered to bring the surface of the receiver C into, driving. contact with the periphery of the roll. The

strand of. yarn 3 or other material is led up from its source of supply and through a tension-device, not herein illustrated, thence drawn across the periphery of the drive-rollmeans are not herein shown and described as they form no part of the present invention.

As the yarn-receiver G is brought into surface contact with the periphery of the driveroll 19 it will be rotated from the roll to wind on the yarn. The roll 19 turns in the direction indicated b the arrow in Fig. 2 and as the yarn is ta en u by the rotation of the receiver C the stran y will enter one or the other of the crossing helical grooves 20 and 21 on the periphery of the roll. As the yarn feeds through the grooves it is trav- 25 ersed thereby back and forth longitudinally of the receiver C to deposit'it thereon in helical coils which make several turns, first in one direction and then in the opposite direction as indicated in Fig. 1; In this way the yarn is "ven a continuous traverse from one end of t e receiver to the other and back again to build up a succession of courses forming overlying layers which constitute the yarn body or package. p At the start of the winding the speed of the yarn-receiver C is approximately the same as that "of the drive-roll 19and the yarn will be laid from end to end of the receiver with a number of turns equal to the number of convolutionsvin the grooves 20 and 21 extending from one end of the roll 19 to the other end. As the yarn builds upon the receiver 0. the latter recedes from the driveroll 19 and with the increase in dia eter of the yarn mass its. angular velocity or speed of rotation is gradually lessened due to the increasing disparity between its diameter and that of the drive-roll. In other words, there is a progressive change in ratio between the speed of rotation of the package and that of the drive-roll and, consequently, there will be a corresponding variation in the number of turns laid on the surface of the package, or in the windas it is called. For example, if the winding is started with four winds, or four turns of theyarn on the surface of the receiver 0 as shown in Fig. 1, as-the package increases in size arid its speed of rotation is retarded ened from four to three, to two,.and so on. At the start of the windingthe coils are laid in open or spacedrelationship, but as the wind 'changes'the spacing between the turns becomes lessened the coils the number of winds will be gradually lessgradually close up crowd or pile on each other. This crowding or piling of the yarn coils takes place each time the wind changes from a greater to a lesser number of even turns and causes what is termed a ribbon wind on the surface of the package. In a package of considerable size there may be a large ing is defective. Where the coils of winding are crowded and piled the yarn in the outer coils is stretched and strained and the turns will not hold in place as well as when spaced apart. Wherwseveral coils are laid one over another in .the ribbon they tend to slip and slide out of place and roll on the surface of the packa This disturbs the twist of the yarn an tends to weaken it so that its quality is impaired and, as anotherserious defect, the ribbon prevents and eventually tend to number of these ribbons and at such points the windthe yarn from delivering freely when it is drawn off over the end of the package.

It has been stated that one object of the present invention is to overcome this defect Y in drum-wound packages by eliminating the ribbon wind and the means for accomplishing this purpose bnsists in the novel arrangement of clutch-operated differential mechanism for varying the speed of one of the winding elements.

Now it would appear receiver C and the package wound thereon are rotated directly from the roll 19 the peripheral speed of rotation of the package would be the same as that of the roll and any acceleration or deceleration in the speed of the latter would be imparted to the package. This is not the case, however, because the package is driven by frictional contact with the drive-roll and there is necessarily some slippagebetween the contacting sur-' faces when the speed of the drive-roll isaltered. The yarn-receiver G and the yarn wound thereon are of considerable mam and the weight of the package increases with'the growth in the winding. Furthermore, the package is rotated at a high rate of considerable. Hen&, when the speed of the drive-roll 19 is retarded the velocity of the package is not materially afiected'so" that it continues its rotation substantially at the maximum. It has been determined in prac tice that due to the slippage between the surno change the ratio-0f the traverse of the yarn" with respect to the rotation of the package being wound;- Stated more specifically, the

speed and the force of momentum is thereforevery be stated that the inter-5 that since the yarnmechanism, that is, the rotating package and the traversing-means for the yarn, is to prevent the crowding and piling of the turns or coils of winding and thus eliminate the ribbon wind usually present in drum-wound packages,

Fig. 3 of the drawings illustrates a modified form of winding mechanism having the ,drive-roll constructed as a separate element from the traverse-roll. of the invention the drive-roll 150 is mounted on and rotated by its own shaft 151 which is driven at a constant rate of speed, either by connecting it directly with the motorshaft or gearing it thereto. The traverseroll 160 is mounted on an independent shaft 161 extending parallel with and located in front of the drive-roll shaft 151. The coptube or yarn-receiver C is carried at the end of an arm 155 pivoted .at 156, being so supported as to adapt it to contact with the periphery of the drive-roll 150 but to be free from contact with the traverse-roll 160. The periphery of the traverse-roll 160, however, is adjacent to the surface on which the winding is performed whatever position the yarnreceiver C may assume so that the yarn y is fed through the grooves of the traverse-roll 160 directly to the package in such manner as to deposit the coils precisely in place thereon as explained in connection with the first described embodiment of the invention.

In the modified form of construction 'shown in Fig. 3, the traverse-roll shaft 161 corresponds'to the driven-shaft 22 referred to in connection with the other views of the drawings, and the variable speed clutchmechanism is carried on this shaft and arranged in exactly the same manner as shown in 4 and previously described. The winding mechanism in this last described embodiment of the invention will therefore operate to cause the yarn-receiver C to be rotated from the drive-roll 150 at a uni formly decreasing rate of speed while the yarn y istraversed longitudinally of the re? ceiver by the separate traverse-roll 160 which has a periodically decelerated rateof movement under the action of the diflerential mechanism herein described.

The result will be the same, that is, a disruption of the synchrony between the rotation of the package and the traversing movement of the yarn with respect thereto so that the piling and crowding of the coils 1s avoided and ribbon winding eliminated.

In this embodiment It will be observed from the foregoing that the present invention provides a particularly simple and efiicient means for 'periodically varying the speed of any certain rotating element constituting a part of the drive for the winding machine, whereby to effect a disruption in the synchrony between two cooperating parts of the winding mechanism. The improved differential clutch-mechanism may be embodied directly in the drive of the machine and comprises a minimum number of elements compacted within a relatively small space.

While the invention is herein shown and described as embodied in'a preferred form of construction and adapted for use with a certain type of winding machine, it is to be understood that various modifications may be made in the form and arrangement of the parts of the device and its method of application which fall within the scope and spirit of the appended claims.
