WINDING MACHINE. l

Application led January 13, 1927'. Serial No. 160,966.

This invention relates to improvements in winding machines for Winding cops, cones or packages of yarn, thread and other attenuated material, and particularly to windt ing machines in which the cop or package is rotated through contact with a friction drive-roll or drum.

The resent invention is directed more particu arly to the means for controlling the .l movement of the copor cone-holder awa from the driving-drum as the package buil s up thereon and for eiiecting the automatic stopping oi. the machine when the cop or package reaches a predetermined diameter.

nUne object of the invention is to provide a machine of the type specitied in which the stopping-mechanism may be set to wind packages of any predetermined diameter through a. simple adjustment of the controlmeans.

Another object ot the invention is to proride a stopping-mechanism which automatically removes the cop from Contact with the drive-roll after it has reached the predetermined diameter and which also disengages the strand of yarn or thread from the coninuous'lypperated traversing threadoru1 e. u Another object of the invention is to protu vide means 'for resetting the stopping-mechanism of the winding machine under manual control to prevent unwarranted stopping of the machine before the winding operation gets under way to pick up the'threadand take up the slack in the delivering strand.

Another object. of the invention is to provide a controllingand stopping-mechanism for the winding machine which is more eilicient in operation and less liable to derangement or getting out of order.

Further objects of the improvement are set iorth in the following speciiication which describes a preferred embodiment of the invention as illustrated in the accompanying drawings. lln the drawings:

Fig. 6 is a detailed view of the detentmeans which normally maintains the stopping-mechanism inactive; and

Fig. 7 is a detailed view of the means for securing'l the dogging-quadrant to the copholder arm.

Referring lirst to Figs. l and 2 of the drawings, 2 designates the rotating drive roll or friction-drum from which the cop or package is driven; 3 the rotating copholder or mandrel on which the cop is Wound, 1n the present machine illustrated in the form of a cone-holder; 4 the reciprocating thread-guide which traverses the strand of yarn or thread longitudinally of the copeholder to deposit it in helical coils thereon; and the rotating cam which rcciprocates the thread-guide 4.

The drive-roll 2 is mounted on a rotating shaft 7 which is driven continuously from suitable power mfeans not herein shown. Usually, the power-shaft 7 is continuous for receiving a plurality of drive-rolls arranged at intervals along the machine frame which vcarries' a number of winding units or heads.

In the present embodiment the cone-holder 3 is rotatably mounted on a spindle 8 carried bv a bearing 9 which is swiveled at the end of an arm 10, see Fig. 2. The arm 10 is hinged on a pivot-stud 11 held in abracket 12 mounted on the machine frame-member 6, whereby to support the cone-holder 3 in position to bear against the drive-roll 2 and to adapt it to swing upwardly therefrom in an arcuate path as the coneor package is built up on the holder. The cone-holder 3 is adapted to tilt on its swiveled bearing 9 as it moves upwardly away from the driveroll 2 to regulate the taper on the periphery of the cone being wound the mechanism for controlling this action being illustrated in general at i3 as embodying the construction shown and described in an application for United States Letters Patent Serial Number 126,897, filed August 3, 1926.

The thread-guide .4 is mounted at the front lot the drive-roll 2 to adapt it to reciprocate longitudinally thereof. As herein illustrated, the thread-guide 4t projects upwardly from a slide lll which is slidable on a horizontal bar or rod 15. A second horizontal har 16 extends in parallel relation above the rod 15 and is engaged by a hooked bearing 17 on the back ot the guide 4 to maintain the latter in erect position as it slides on the rod 15. The rod 15 and bar 16 are secured in place at the front of the machine by lneans ot suitable bearing-blocks '18, see Fig. 2, which clamp them against the vertical arms 19 forming a part ot' the frame-members The slide 14 is provided with a lug 22 through which extends a. stud 23 carrying a bowl or roller 24 at its lower end which engages with the helical groove 25 in the cam 5. As herein shown the cam 5 has a second groove 26 of different pitch in its periphery which may be alternatively employed to reciprocate the guide 4 in the manner as known in the art. vThe cam 5 is carried on a continuously rotating shaft 27 which extends throughout the length ot' the machine frame to operate the cams for other winding units mounted thereon. 1t will be apparent that the rotation of the cam 5 causes the guide 4 to reciprocate back and forth at the front of the drive-roll 2, and the upper end of the guide is inclined inwardl toward the point of contact of the cop with7 the periphery of the drive-roll and provided with a suitable thread-groove 28 through which the strand y leads to direct it onto the cop. The guide 4 is also provided with a hook 29 overlying its face t0 adapt it to pick up the strand of thread or yarn to lead it into the thread-groove 28. The above described instrumentalities constitute the essential elements of the winding mechanism of the machine and are similar in general construction and arrangement to those heretofore employed in the art.

It has been noted that as the cop or cone Y, see Fig. l, builds up on the holder 3 the latter swings upwardly on the arm 10, and suitable dogging-means are usually provided for steadying the motion of the cone-holder' and preventing a retrogressive movement thereof. The present lnvention contemplates the employment of an improved dogging-mechanism for this purpose which provides for greater simplicity of construction and is adapted to cooperate with the sto ping-mechanism of the machine to arrest-t e winding operation when the cop or package reaches a predetermined diameter or size. As herein illustrated the dogging-mechanism comprises an arcuate slide yor quadrant 30 which depends from the swinging arm 10. Referring to Figs. 2 and 7, the quadrant 30 is held in an arcuate slot 31 on the side ot the arm l0 and is clamped in position by means of a bolt 32 and washer 33 overlyme' its side. Through this arrangement the quadrant 30 may be adjusted in the slot to regulate the extent to which it projects below the arm 10, this adjustment providing for setting the quadrant tx) trip the stopping-mechanism when the arm 1t) has been moved upwardly to a )redetcrmined extent in accordance with the diameter ot' the cop or package to be wound.

The (logging-means which cooperates with the quadrant 30 to act l'rictionally thereon to prevent retrogressive movement of the arm 10 consists of a sliding rod or bar 35 which also forms the tripping-means or trigger for the stoppiiig-mechanism. As shown in Figs. 2 and 3, the slide 35 is mounted to slide through a slotted hearing 3G formed on an extension 37 ot the hrm-kot l2. The slide or bar 35 is provided with two longitudinal slots 38 which are engaged hy pins 39 and 4() to hohl the slide in suspension; the rearward pin 39 being driven through the sides of the slotted bearing 36 and the forward pin 40 projecting from the side of the l'iearing-block 18 previously referred to as fastened to the arm 1t) of the frame-member 6. At the rearward end o"v the slide 35 is an upstanding inclined arm 4. formed with a beveled face 43 which is adapted to engage the forward convex face ot' the quadrant 30, see Fig. 2. A spring 45 is held against the rearward side of the bearing 36 with its opposite end bearing against. a pin 46 driven through the slide 35 whereby it acts to urge the slide reaivwardly to cause its end 43 to bear against the quadrant 30 to frietionally resist the movement ot the quadrant across the slide. As a result of this construction and arrangement the slide or dog 35 is caused to bear against the quadrant 30 to resist the upwa rd swinging movement ot the arm 10 as the package wound on the holder 3 increases in diameter and to also act frictionally to check retrogrcssive or downward movement of the arm. The movement of the coneor cop-holder 3 away from the drive-roll is thus frictionally controlled to provide a smooth, vibrationless motion whereby the cop or cone is prevented from jumping and rebounding with respect to the drive-roll.

As a novel and improved feature of the present invention the dogging-mechanism is designed to vary the rictional resistance to the movement of the copor cone-holder as the cop or cone increases in diameter. That is to say. the. (logging action is differential in accordance with the growth ol' the package,

,the resistance to the movement of the cone holder being at its maximum at the heginning of the winding and gradually dccreasing as the package grows in size and weight. This differential action is in accordance with a well-known principle ot winding based on the fact that more pressure can be applied to the package when a relatively small body or mass surrounds the holder than when the yarn mass reaches a considerable diameter so that it is softer and more desirable to compress the first layers of lltl windin tothe maximum density to provide a' lirm ondationujor subsequent la ers and this result is obtained by applymgt e maxlmum pressure tojthe copor cone-holder'at the start ofthe winding and gradually decreasing the pressure as the package 1ncreases in diameter.,.'l`his result 1s secured in the present invention by a novel and 1ngenious arrangement of the quadrant 'which is disposed in eccentric relation to dlill llll liti

llll

lit

the pivot 11 of the swinging arm 10..` By reference to the dotand-dash line in Fig. 2, which defines an arc struck on the pivotal axisiof the arm 10, it will be noted that the quadrant 30 does not conform to this arc, but on the contrary is dis osed eccentric thereto. It will also be note that the upper part of the quadrant 30 is of .greatest eccentricity, being furthest removed `from the axis of the arm 10,'while the lower depending portion of the quadrant gradually approaches the axis. It will thus be apparent that with the cone-holder 3 bearing against the drive-roll 2 .at the start of the winding, as shown in Fig. 2, theslide or dog will be forced back to holdthe spring under maximum compression; while as the coneholder arm 10 rises the diminishing eccentricity of the quadrant 30will cause the slide 35 to gradually slide to the right to reduce rthe compression of the spring 45. ln this way the friction action of the dog 42 nn the quadrant 30 is reduced to gradually decrease the resistance to the sliding motion af the quadrant and thereby the resistance to the upward movement of the copor coneholder 3. It will be observed that through this simple arrangement and construction ap ecient mechanism is provided for applying resistance to the movement of the cop or cone-holder away from the drive-roll with a differential pressure in accordance' with the increase in size of the package being maand.

lt has been stated that the slide 35 acts.

asthe trip for the stopping-mechanism ofthe machine, the dog 42 beingadapted to slide olf from the end of the quadrant 30 afterthe paclrage has reached a predetermined dianieter in accordance with the adjustment of the quadrant on the arm 10. The instrumentalities which cooperate with the slide 35 to arrest the Winding operation are illustrated in detail in Figs. 3 to 6 and will be next explained. To arrest the rotation of the copor cone-holder 3 the arm 10 is lifted to remove the package from contact with the drive-roll 2 as is the usual practice in machines of the present type. The lifting of the cone-holder 3 is accomplished by positively raising the arm 10 by means of a ratchet-mechanism, shown in detail in Fig. 5,-

which acts on the quadrant 30. It will be notedfrom this view that the quadrant 30 is formed with ratchet teeth 49 which are on the rearward side of the uadrant asviewed in Figs. 2, 3 and 4 so t at they do not show in full in these views. Adapted to engage the teeth 49 on the quadrant 30 is aJ pawl 50 which is pivoted at 51 to a swinging lever 52, see Fig. 5. The pawl 50 has a tail-piece 53 acted upon by a plunger 54' which is under the pressure of ,a sprlng 55 held in a poclet depending from the lever 52. The spring 55 maintains the pawl 50 in engagement with the teeth 49 and preferably the bearing of the pawl on its pivot 51 is made more or less loose to provide play so that the pawl may adjust itself'to the teeth ivhen the quadrant 30 is moved a distance less than the length of a tooth.

The lever 52 is ixedly secured to the end of a rod 56 which is rockably mounted in a bearing 57 forming a part of the bracket 37 on the ramemember 6 as shown in Fig. 2. The rod 56 has a second bearing 48 at thepfront of the frame-member 6. The rod 56 also forms the lock or detent for maintaining the stopping-mechanism normally inactive, `its forward end being bentfinto a crook at 58 and terminating in an inclined arm 59 formed with a pointed detent-blade 60, see Fig. 6. The detent-blade 60 is adapted to engage a notch or shoulder 61 on a" latch-plate 62 which is fastened to the top' shown in Fig. 2 with its upper end engaging A the hooked end 68 of an ar'n 69 on the lever 52. A stopescrew 70 screwed through the arm 69 and locked in place by a checknut 7l is adapted to strike against the top of the bracket 37, see Figs. 2 and 5, to lirnitthe rocking-motion of the lever 52 under the action of the spring 67. When the detentrod 56 is released the spring 67 will rock the lever 52 carried thereon to lift the pawl 50 to a certain extent as regulated by the adjustment of the stop-screw 70. The lifting of the pawl 50 in this manner acts through the ratchet on the quadrant'() to slide the latter upwardly Awhereby to raise the arm 10 to lift the package, indicated at Y in Fig. 3, out of contact with the 4 l. guapas l drive-roll 2'to arrest the winding operation it is necessary that the strand y belifted out of the groove in the guide to prevent the yarn or thread from being cut orl broken.;I The rockable member 65, previously ref erred to as carlyinv the latch-plate 62, constitutes' the threa lifter for disengaging the strand y from the thread-guide 4. As shown more particularly in Figs. 1 and 3, the threadlifter 65 is constructed in the form of a relatively fiat plate provided with opposite socketed bearingsy 7 -l\ which are supported ou trunnion-pins 75 projecting inwardly from the frame-members 6. Studs'76 are screwed through the. bearings 74 to en age beneath the pins 75 to hold the thread-lifter in lace on its trunnions' to pivotally support it t erefrom. Asy shown in Fig. 2,-the thread-lifter 65 normally assumes a position with its upper edge at the rear of and below the guidlng-groove 28 in the thread-guide 4, being retained i'n this positionby the engagement of thelatch-plate 62 with the detcntlade 60 on the rockable rod 56. The thread-lifter 65 is rocked into the position shown in Fig. 3 to release the detent-rod 56 and to act concurrently to lift the strand 7/ out of the groove in the thread-guide 4 in the manner as later explained. This action of the Athread-lifter is. eiected through the cooperation of instrumentalities as next4 described.

Referring to Fig. 3, a bifurcated lever 77 is pivoted to the in- 40 whichv supports the forward end of tiie slide 35 with its opposite legs straddling the sides of the slide. The lever 77 has an elbow-shaped arm 78` which vis formed with an inclined slot 79 engaged by a pin 80 projecting from the side of the slide 35. When the slide 35 is slid into the position shown in Fic'. 3 under the pressure of the spring 45 the pin 8O slides in the slot 79 to )tilt the elbow-shaped arm 78 of the lever77 upwardly. The end of the arm 78 of the lever 77 is hooked un-I der al crank-arm 81 which, as shown in Fig.

1, forms part of a Wire rod 82 pivotally mounted in lugs 83 on the under side of the thread-lifter 65. The crank-arm) 81. has a i hook 84 at its end to which is connected a wire link 85. T e link 85 is hooked beneath the tail-piece 8 which, as shown in Fig. 3, is pivoted on a pin 89 and constitutes the activeelement for rocking the thread-lifter to release the detent for the stopping-mechanism. `The lever 87 is constructed of sheet-metal with -a bifurcated portion 88, the sides of which l straddle a lever 90 carrying the pivot-pin 89. The lever '90 is pivoted on a pin 91 driven into the. side of the frame-member 6, see Fig. 1, and its upper end is bent over at 92 to adaptit to engage a tail-piece 93 projecting at an angle from one of the bearings of the thread-lifter 65. The tail-piece 86 on the lever 87 projects into position to of a. knoek-off lever 87'A ladapt its end to be enffaged'by atoothed collar or wheel 95 whic is secured to the cam shaft 27 to rotate therewith. A pin 96 projecting from the side of the frame-meiner 6 limits the upward movement of the tail-piece 86 on the lever 87 whereby when the end ofthe tail-piece is engaged by a tooth on. the wheel 95 the lever will be moved bodily to rock the connected vlever 90 in the direction indicated by the arrow a in Fig;` 3. This rocking action of the lever 90 brings its heut portion 92 against the tailpiece 93 on the thread-lifter 65 to rock the atterto raise the thread out of the threadguide while releasing the detcnt for the stopping-mechanism in the manner as hereinafter more fully explained.

The lever 87 may also be rocked to engage its tail-piece 86 with the toothed wheel 95 to arrest the winding operation when the strand breaks b f means of a breakage-lever 125, shown in igs. 1 and 2. The lever 125 extends forwardly from the rod 82, being rockable on the rod independently thereof. A collar 126 is fast on the rod 82 and has a slot 127 in which the lever 125 plays. This arrangement provides that the lever 125 may rock upwardly without turnin the rod 82,

Abut when it drops it engages t e end of the slot 127 in the collar 126 to turn the rod 82 to lift its arm 81. In this manner when the breakage-lever 125 is released from the tension of the strand y it will dro to raise the arm 81 to cause it to act throng 1 the link 85, see Fig. 3, to carry the tail-piece 86 of the lever 87 into position to be engaged by the teeth on the rotating collar or wheel 95. This arrangement is similar to the usual breakagelever mechanism for arresting the winding operation when the thread or yarn breaks.

Manuall -operable means are provided for releasing t e cone-holder 3 to return it into driving connection with the drive-roll 2 and to concurrently reset the stopping-mechanism to start the winding operation. This manually-controlled means also operates to v return4 the thread-lifter toI normal position and the instrumentalities employed for this purpose are illustrated in Fig. 4. They comprise essentially a bifurcated frame 100 havlng opposite legs 101, see Fig. 1, pivoted on the trunnion-pins which support the thread-lifter 65. The two legs 101 of the frame 100 depend below the thread-lifter 65 and are connected by a cross-strip or web 102. Bolted to the cross-strip 102 is a curved handle or starting-lever 105 which reaches outwardly from the front of the ma chine in convenient position to be grasped by the operator. Referring to Fig. 1. the right-hand leg 101 of the frame 100 is extended upwardly in an inclined arm 106, see also Fig. 4, .which has a flat plate-like portion 107 normally lying adjacent and in alinement with the main plate portion of the threadtid lifter 65. The plate`107 is curled over at the ttp in an extension 108, see Fig. 4, which is a apted to engage beneath the crooked portion 58 ot the detent-rod 56 to rock the latter to engage its detent-blade 60 with the Llatch-plate 62. The arm 106 of the frame 100 is also provided with a Web-like exten sion 109 which is engaged by the hooked end 110 of the slide 35, see Fig. 4. It will thus be observed that when the starting-handle 105 is depressed into the position illustrated in Fig.. 4 the traine 100 will be rocked to cause its arin 106 to slide the slide35 to move its dogging-arm 42 into position to engage the quadrant 30. .During this operation the hnger or extension 108 on the arm 106 rocks the detent-rod 56 to engage its blade 60 with the latch-plate 62 and this rocking motion oit the rod 56 also operates to rock the lever 52 to release the pawl 50 from the ratchetteeth on the quadrant 30, the functioning ot these parts to start the winding operation being more tully explained hereinafter.

A spring 111 normally holds the iframe 100 in the position illustrated in llig. 2 with its extension 108 bearing against a lug or rest 112 on the bearing-block 18. The spring 111 is connected at 118 to the trame 100 with its opposite end anchored to a pin 114 held in the side of the block 18.

Referring to hig. 4, a bell-crank lever 115 is pivoted on the pin 91 which 'lorins the pivn otal support itor the lever 90 and one ot' its arms 116 reaches upwardly and is bent over in a linger 117- which engages a hole 118 in a lug 119 at the end ot the cross-strip 102 oil the trame 100. The lower arm 120 of the lever 115 is adapted to engage the tail-piece 86 ot the lever 87 to depress the latter to hold its end tree trom the teeth on the wheel 95, the lever 115 being rocked to effect this action as shown in liig. 4 when the starting lever 105 is depressed to start the winding operation. rllhe method of operation ot the complete machine is as follows:

Assuming that the winding has been arrested with the copor cone-holder 3 held in raised position above the drive-roll 2 throughthe means ot the ratchet pawl 50 acting on the teeth 49 of the quadrant 30, the machine is prepared for operation by placing a paper shell or tube 'l on the mandrel or holder'. The strand y of #yarn or thread is drawn up from its source ot supply, not herein shown, and led under the reakagelever 125, thence across the upper edge of the thread-lifter and its end secured to the cone-tube T.

With the winding operation arrested the parts of the stopping mechanism are in position substantially as shown in Fig. 3. To start the winding the operator grasps the starting-lever 105 and presses it downwardly against the tension of its spring 111, see Fig. 2, to the position illustrated in Fig. 4.

The depression of the lever 105 rocks the frame 100 and the latter acts through its 4 that the friction-dog 42 is moved back to clear the quadrant 30 as shown at the right in this view. As soon as the slide 35 has ,been withdrawn in this manner the further movement ot the rocking i'raine 100 causes its extension 108 to engage the crook or crank 58 at the end ot the rod 56 to turn the latter to rock the lever 52 carried at its end. The lever 52 is thus rocked against the tension of its spring 67, see Fig. 5, thereby causing the pin 47 to act against the pawl 50 to cause the latter to be swung away from the teeth 49 on the quadrant 30. lim mediately the pawl 50 is released the weight of the arm 10 and the parts carried thereby will cause the arm to swing downwardly on its pivot 11 to lower the cone-holder 8 to bring the surface ot the cop-tube carried thereon into contact withthe periphery ot the continuously rotating drive-roll 2. The,

contact oit the cop-tube with the drive-roll will therefore cause the cop-holder or wind-` ing-mandrel to be rotated ytherefrom in the direction indicated by the arrow 5 in llig.. 4. `its thecone-holder is lowered against the drive-roll 2 the quadrant 80 slides down into position to adapt the dog 42 to be trictionally engaged with its convert surface at'ter the slidev 35 has been released to allow it to slide forward under the'action oit its spring 45. 'lhis release ot thc slide 35 does not taire place, however, until the startinglever 105 has been released by the operator. Previous to this release of the slide 35 the downward movement ot the lever 105 and the rocking action ot the trame 100 caused thereby acts through the bell-crank lever 115 to cause the arm 120 of the latter to press the tail 86 ot' the lever 87 downwardly to remove it trom possible contact with the toothed wheel 95.- rl'his action of the bell cranlt lever 115 thus serves to prevent nnwarranted arrest ot the winding operation while the strand y oi thread on yarn is slack and the breakage-lever 125 droppedso that it will not free the lever 87 or, in other words, lower it away from the toothed wheel 95..

lt should be stated that when the threadlitterl 65 is tilted or rocked upwardly through the action of the lever 90 in arresting the winding operation it is held in this position as shown in Fig., 3 by means of the blade 60 of the datent-rod 56 which slides along the inclined edge 64 of the detent-plate 62 to the lposition shown in dotted lines in Fig. 6. ln starting the winding operation, therefore, when the startinghandle 105 is depressed to cause the eatenllll sion 108 on the frame I100 to rock the crank arm 58 of the rod 56 the blade 60 will be slid away from this enga ement as last described to allow the threa -lifter 65 to drop into the osition shown in Fig. 4 under the action ofp gravity. At this point the blade l60 on the detent-rod 56 is carried into ention to the thread-guide 4 that it will be picked up by the hook 29 on the guide to seat it in the oove 28 as shown in Fig. 1. This automatlc threadin of the threadguide takes place when t e uide reciprocates to the right as shown 1n Fig. 1, the traverse of the guide in the opposite direction causing the strand to ride up over the curved portion of the hook 29 to adapt it to be plcked up at the next reverse movement of the guide. As the strand y of yarn feeds to the rotating cone-holder or Winding-mandrel 3 its slack is taken up and the breakage-lever 125 is suspended thereby to prevent it from influencing the breakagelever 87 to cause arrest of the winding operation. The operator can now release the starting-lever 105 and the frame 100 will be returned to normal osition as shown in Fig. 2 under the action of its spring 111. Wlth the parts of the mechanism set in this relation the winding operation will cony tinue with the thread-guide 4 transversing the strand y back and forth longitudinally of the cone-holder 3 to direct it onto the cop-tube T in a series of helical turns extending lfrom one end of the holder to the other and crossing each other at intervals. The cone or package is thus built up with a series of overl ing layers of the helical turns of yarn or t read, the winding operation bein continuous until the yarn breaks or is eziliausted, or the package reaches a predetermined size. .l

Should the strand g/ break the breakagelever 125 will drop to raise the tail 86 of t e knock-off lever 87 into the position shown in Fig. 3 to operate the stopping-mechanism of the machine in the manner as previously explained. Likewise, when the cone reaches a predetermined diameter the stopping-mechanism is released through the disengagement of the quadrant 30 from the dog 42 in the manner as next ex ilained. As the quadrant 30 is carried up with the arm 1() supporting the cone-holder 3 its end finally rides off from the dog or extension 42 of the rod 35. This permits the rod 35 to slide to the right under the action of its spring 45 as shown in Fig. 3 and the pin 80 at the opposite end f the rod will thereby act through the slot 79 1,eue,osa

in the lever 77 to rock the elbow-shaped arm 78 of the latter upwardly. The lever 77 is thus caused to act through the crank arm 81 and link 85 to lift the tail 86 of the knockof lever 87 to bring it into osition to be engaged by the teeth on the w eel 95. The ro-A tation of the wheel 95 will therefore cause the knockoif lever-87 to rock the lever 90, thus acting through the tail-piece 93 on the thread-lever to tilt the latter upwardly to withdraw the strand y of thread or yarn from the threaduide 4.

As before exp ained, the raising of the thread-lifter 65 releases the detent-shoulder 61 on the plate 62 from the blade 60 at the end of the rod 56, allowing said rod to be rocked under the action ofthe spring 67 connected to the lever 52. The rockin of the lever 52 acts through the pawl 50 to orce the quadrant 30 upwardly whereby the arm 10 is raised to lift the cone-holder 3 t0 remove the cop or cone from contact with the periphery of the drive-roll 2 as shown in Fig. 3. The rotation of the cone-holder 3 is thus arrested and the strand y of yarn or thread released from the thread-guide so that the winding ope-ration ceases until the stoppingmechanism is manually operated again in the manner as previously explained. It has been before noted that the blade 60 on the rod 56 slides along the beveled edge of the detentplate 62 to the position shown by dotted lines in Fig. 6 to act asa holding-means to maintain the thread-lifter in raised position until the winding operation is started again, and in this Way the winding-mechanism is maintained inoperative until the machine is prepared to wind again.

It will be observed from the foregoing that the invention provides an efficient means for controlling the winding operation automatin cally to cause the Winding to be arrested either when the strand breaks or when the cop, cone or package reaches a predetermined diameter. The improvement further provides that when the winding operation is being started slackuess in the strand of thread or yarn, vibration of the breakage-lever, or any other abnormal condition cannot act to cause premature or unwarranted arrest of the Winding operation.
