embodying the construction shown and described in U. S. Letters Patent, No. 1,658,400, dated February 7 1928.

The thread-guide 4 is mounted at the front of the drive-roll 2 to adapt it to reciprocate longitudinally thereof. As shown in Fig. 2 the thread-guide 4 projects upwardly from a slide 14 which is slidable on a hori zontal bar or rod 15. A second horizontal bar 16 is engaged by a hooked bearing 17 on the back of the guide to maintain the latter in erect position it slides on the rod 15. The rod 15 and bar 16 are secured in place at the front of the machine by means of suitable bearingblocks 18, see Fig. 1, w ich clamp them against the vertical arms 19 forming a part of the frame-mem- 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. The cam 5 is carried on a continuously rotating shaft 27 which extends throughout the length of the machine frame to operate the cams for other winding units mounted thereon. The rotation of the cam 5 causes the guide 4 to reciprocate back and forth at the front of the driveroll 2, and the upper end of the guide is inclined inwardly toward the point of contact of the cop with the periphery of the drive-roll and provided with a suitable thread-grove 28 through which the strand z leads to direct it onto the cop. 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 builds up on the holder 3 the latter swings upwardly with its supporting arm 10, and suitable dogging-means are usually provided for steadying the motion of the conedepends from the swinging arm 10.

holder and preventing a retrogressive movement thereof. In the present invention the dogging-means comprise an improved construction over that described and illustrated in the prior application first referred to. As in the prior invention, the doggingmeans is adapted to cooperate with the stopping-mechanism of the machine to arrest 'the winding operation, but in a somewhat different manner. In the previously shown construction the dogging mechanism comprises an arcuate slide or quadrant 30 whliich eferring to Fig. 1, the quadrant 30 is held in an arcuate slot 31 on the side of the arm 10 and is clamped in position by means of a bolt 32 and washer 33 overlying its side. Through this arrangement the quadrant 30, which is employed as a slidable element for actuating the stopping-mechanism, 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 to trip the stoppingmechanism when the arm 10 has been moved upwardly to a predetermined extent in accordance with the diameter of the cop or package to be wound. This same arrangement of the quadrant 30 is employed in the present construction.

The dogging-means which cooperate with the quadrant 30 to act frictionally thereon to prevent retrogressive movement of the arm 10 comprises the previously disclosed sliding rod or bar 35 which also forms the trippinganeans or trigger for the steppingmechanism. As shown in Figs. 1 and 2, the slide or bar is mounted to slide through a slotted bearing 36 formed on an arm or extcnsion 37 of the bracket 12. The slide or bar is provided with two longitudinal slots 38 which are engaged by pins 39 and 40 to hold 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 bearing-block it; previously described as fasned to the arm 19 of the frame-member 6. Instead of arranging the slide 35 to bear directly on the quadrant 30 to effect the dog gin g-action, as in the device of the prior application first referred to, in the present invention the dogging-means is constituted as a separate element connected to be operated from the slide. As shown in Figs. 1, 5 and 8, the extension 37 of the bracket or frame-member 12 has an arm 41 extending upwardly therefrom and carrying a pin 42 fast in its upper end. Pivoted to rock on the pin 42 is a bifurcated dogging-element or lever 43, shown in detail in Fig. 7 arranged with its opposite arms 44 straddling the sides of the quadrant 30, see Figs. 5 and 8. The lower end of the dogging-member 43 is offset slightly to abut the side of the slide 35 and is provided with a lip 34 at the bottom adapted to engage a slot 26 on the under side of the slide. The two arms 44 of the dog 43 are connected by a cross-strip 29 having its edge beveled to adapt it to act as a shoe engaging against the convex face of the quadrant 30 as shown in the detailed View, Fig. 9. Through this arrangement the fixed pin 42 engages one side of the quadrant'and the cross-strip or shoe 29 bears against the opposite side so that when the ,dog is rocked on the pin 42 it will exert a frictional binding action on the quadrant to resist the downward sliding movement of the'latter. This actionprevents retrogressive movement of the copholner after the latter has been forced upwardly by the growth in the winding.

The dog 43 is rocked to effect the frictional gripping action through the sliding movement of the slide 35 connected to its the trip for the lower end by means of the lip 34 and. slot 26, the slide being under the influence of resilient means such as the spring-45'. The spring 45 surrounds against the rearward side of the bearing 36 with its opposite end pressingagainst a pin 46 driven through the slide. The spring 45 thus acts to, adjust the slide rearwardly with respect to the front of the machine to rock or tilt the dog 43 to press the beveled face of its shoe'29 against the convex face of the quadrant 30. The dog thus acts both to resist the upward swinging movement of the arm carrying the cop-holder 3 and to more positively check retrog-ressive movement of the arm in the manner as before explained. The movement of the coneor cop-holder 3 away from the driveroll 2 is thus more efficiently controlled to provide a smooth, vibrationless motion whereby the cop or cone is prevented from jumping or rebounding with respect to the drive-roll during the winding operation.

It has been stated that the slide 35 acts as stopping-mechanism of the machine, the engaging portion or'shoe 29 of the dog 43 being adapted to slide ofi from the end of the quadrant 30 after the package has reached a predetermined diameter in accordance with the adjustment of the quadrant on the arm 10. The instrumentalities which cooperate with the slide to arrest the winding operation are illustrated in detailin Figs. 2 to4 andwill benext ex-,v plained. To arrest the rotation of the copor cone-holder 3 the arm 10 is lifted to re move the package from'contact withfthe.

practice'in ma: The lifting of drive-roll 2 as is the usual chines of the present type.

the cone-holder 3 is accomplished by positively raising the arm 10 through the means of a ratchet-mechanism, shown in detail in Figs. 5 and 6, which acts on the quadrant 30. It will be noted from these views that the quadrant 30 is formed with ratchet teeth 49 on its rearward side as viewed in Figs. 2 and 4. Adapted to engage the teeth 49 on the quadrant 30 is a pawl 50 which is pivoted at 51 to a swinging'lever 52, see Fig. 6. The pawl 50 has a tail-piece 53 acted upon by 'a plunger 54which is under the pressure of a spring 55 heldin a pocket depending from the lever 52. The spring55 maintains the pawl 50 in engagement with the teeth 49 and, preferably,-the bearing of the pawl on its pivot 51 ismade more or less loose to provide play so that the pawl may adjust itself to the teethwhen the quadrant 30 is moved a distance less than the length of a tooth.

The lever 52 is fixedly secured to the end of a rod 56 which is rockably mounted in a bearing57 forming. a part of the arm '37 on the frame-member 6 as shown in Fig. 2.

F: The rod 56 has a second bearing 48 at the the slide 35 and is held,

front of the. frame-,member 6ias' shown in Fig. 1. The rod 56 also forms the lock or et t anism normally inactive, itsforward end being bent into a crook at 5 8 and terminat ing in an inclined arm 59 fori'ned with a pointed detent-blade 60, see 8, ,The detent-blade 60 is adaptedto engage a notch or shoulder '61 on a latch-plate 62 which is fastened to the top of a post 63 projecting upwardly from arockable member 65, shown in Fig. 2 and later described. The latch-plate 62 is adapted to be rocked into the position shown by dotted lines in Fig. 8, whereby the detent-blade 60 is released from the shoulder 61 to cause it toslide along the inclined edge 64 of. the plate 62 in the mam ner and 'for the purpose as hereinafter eX-. plained. The release of the detent-blade 60, permits the rod 56 to be rocked under the infiuenceof a spring 67 which is anchored to the frame-member 6, see 9 per end engaging the hooked end 68 of an arm 69 on the lever 52, see also Fig. 6. A stop-screw 70 screwed through the arm 69 and locked in placeby a checknut 71 is adapted to strike against the top of the arm 37, see Figs. 1 and 5, to limit the rocking-' motion of the lever 52 under the action of the spring 67. \Vhen the detent-rod 56 is released the spring 67 will rockthe 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 30 to slide the latter upwardly whereby toraise thearm 10 to lift the package, indicated at Y in Fig. 2, out of contact with the drive-roll 2 to arrest; the winding operation. It will thus be apparent that the lever 52, the pawl 50 and the spring'67 constitute the means hereinafter referred to as the stopping mechanism for arresting the operation r I the machine.

It has been noted that .the threadsguide 4 is reciprocated continuouslyfand there,- fore 'as' the cop oncone is lifted away'fro m the drive-roll. 2 to arrest the winding opera;

tion it is desirable that the strandfz be refor maintaining the stopping-moch Fig.1, with its upmovedfrom'the guide to preventithe' yarn or thread from being. cut or broken. The rockable member '65, previously described as carrying the latch-plate 62, constitutes the thread-lifter for disengaging the strand 1 from the thread-guide 4. As, shown in Figs. 2 and 4, the thread-lifter 65.- is constructed in the form of a relatively flat plate provided with suitable trunnion bearings on the main frame of the machine. Referring to Fig. 4, the thread-lifter normally assumes a position with its upper edge at the rear of and below the guiding-groove 28 in the thread-guide 4, being retainedin this positionby the engagement ofthelatchplate 62 with the detent-blade 60 on the rockable rod 56. The thread-lifter 65 is rocked into the position. shown in Fig. 2 to release the detent-rod 56- and to act concurrently to lift the strand y out of the groove in the thread-guide 4 in the manner as later explained. This action of the thread-lifter is effectedthrough the cooperation of instinmentalities as next described.

Referring to Figs. 2, 3 and 4, a bifurcated lever 77 is pivoted to the pin 40 which supports the forward end of the slide 35, the opposite legs of the lever being straddled across the slide. The lever 77 has an elbowshaped arm 78 which is 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 Fig. 3, under the pressure of the spring 45, the pin 80 slides in the slot 79 to tilt the elbow-shaped arm 78 of the lever 77 upwardly. The end of the arm 78 of the lever 77 is hooked under a crank-arm 81 which, as shown in Fig. 2, 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 hook 851 at its end to which connected a wire link 85. The link 85 is hooked beneath the tail-piece 86 of a knockoff lever 87 which is pivoted on a pin 89 projecting from the side of a lever 90. The lever 87 has a bifurcated portion 88, the sides of which straddle the lever 90. The lever 90 is pivoted on a pin 91 driven into the side of the frame-member 6 and its upper end is bent over at 92 to adapt it to engage a tailpiece 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 adapt its end to be engaged by a going element of the machine, such as the toothed collar or wheel 95 which is secured to the cam-shaft 27 to rotate therewith. it pin 96 projecting'from the sideof the ma chine frame limits the upward movement of the tail-piece 86 of the lever 87 whereby when the end of the tail-piece is engaged by a tooth on the wheel 95 the lever will be moved bodily to rock the connected lever 90 in the direction indicated by the arrow in Fig.3. This rocking action of the lever 90 brings its bent portion 92 against the tailpiece 93 on the thread-lifter 65 to rock the latter toraise the thread out of the threadguide'while releasing the detent 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, a suitable breakage-lever 125 shown'in Fig. 4 being employed for this purpose. The breakage-lever 125 extends outwardly from the rod 82 and is adapted to rock said rod when released from the strand y. The lever 125 acts in the manner explained in the previous application to raise the arm 81 to cause it to act through the link 85 to lift the tail-piece 86 of the lever 87 into position to be engaged by the rotating collar or wheel 95 in the manner as shown in Fig. 3.

'Referring now to Figs. 2, 4i and 8, the detent-rod 56 carries a lever 128 having its hub abutting the side of the bearing 57 and secured fast to the rod by means of a binderscrew 129. The lever 128 has a bevel-sided lug 130 at its lever end which is adapted to co-act with the inclined side of an upright arm or cam-plate 131 fastened to the slide 35. As shown more particularly in Fig. 8, the cam-plate 131 is riveted to the rearward side of the bar slide 35 at 132 with its arm reaching upwardly therefrom and outwardly in front of the rockable rod 56. At its upper end the arm is extended in a nar row portion or finger 133 adapted to bear against the side of the rod 56 to take the thrust of the cam-plate 131 when the latter is acted upon by the lever 128. As shown in Fig. 8, the cam-plate 131 is bent to form the inclined face 134 against which the beveled lug 130 engages when the lever 128 is rocked with the rod 56. The lever 128 will. thus effect prying action on the camplate 131 to slide the slide 35 to the left as viewed in 2 against the action of its spring 41-5. The purpose of this arrangement, which is a feature of improvement Over the mechanism described and illustrated in the patent first referred to, is to release the knock-off lever 87 from engagement with the toothed wheel 95 after the operation of the machine has been arrested. That is to say, after the knock-olf lever 87 has been lifted to engage its tailpiece 86- with the rotating wheel 95 and the stoppingmechanism has functioned it is desirable to release the knock-off lever so that it will not be continuously actuated and caused to chat- .ter under the intermittent engagement of the teeth with its end. The slide 35 is slid to the left to slide the pin 80 in the inclined slot 79 in the lever 77 whereby to release the lever 87, this action being more fully explained in the method of operation of the complete machine.

lllanually-operable means are provided for releasing the ratchet to return the coneholder 3 into driving connection with the drive-r0112 and to concurrently reset the stopping-mechanism to start the winding operation. This manually-controlled means also operates to return the thread-lifter to normal position and the instrumentalities employed for this purpose are illustrated in Fig. 1. They comprise, essentially, a bifurcated frame pivoted on the trunnionpins 7 5 which support the thread-lifter 65. Bolted to the depending portions of the inc engage its frame 100 is a curved handle or startinglever 105 which reaches outwardlyfrom the front of the .machine 'in convenient position to be grasped by the operator. 7 Referring to Fig. 4, one end of-the frame: 100 isextended upwardly inan inclined arm 106 which normally lies adjacent and in valinement with the main portion of the thread-lifter +65. The arm 106 is curledover at the top in an extension 10.8,.see' Fig. 4, .which is adapted to engage beneath the crooked portion 58 of the 'detent-rod 56 to rock-the latterto detent-blade .60 with the latchplate 62. The arm 106 of the frame 100 is also provided with .a web-like extension 109 which is engaged .by :the shocked end 110 :of the slide 35. It will thus be observed that when the starting-handle105 is depressed into the position illustrated in Fig. 4 the frame 100 will :be rocked to cause its arm 106 to slide 35 1'60 move :the' dog 43 into position .to adapt the quadrant to slide I Dun down against the shoe 29 on the dog. ing this operation the finger or extension 108.011 the arm 106 rocks the detent-r-od 5.6 to engage its blade 6Q'Wlth the latch-plate 2 and this rocking .motion of the rod 56 also operates to rock the lever 52 to release the pawl 50 from the ratchet-teeth on the quadrant 30, the functioning of these parts .to start .thewinding operation :being more fully. explained hereinafter."

A spring 111 normally holds the frame 100- in the position illustrated in Fig. 1 with its extension 108 bearing against a lug or rest 11-2 on the bearing-block 18. The spring 1111 is connected at 113 to the frame 100 with its-opposite end anchored to a pin 114' held in the'side of the block18. I

Referring again to Fig. 4, a bell-crank lever 115. is pivoted on the pin 91 which forms the pivotal support for the l'everg90 and one of its arms 116 reaches upwardly and is bent over in a finger 117 which engages through a hole 118 in a lug 119 011 the frame 100. The lower arm 120 of the lever 115 isadapted to engage the tail-piece 86 of the lever 87 todepress its free end from the teeth on the wheel 95, the lever 115 being rocked to efiect this action as shown in Fig. 4 when the startinglever 105 is depressed to start the winding operation. The method ofOperationof the complete machine is as follows: p

. Assuming that the windinghas been a-rrested with the copor cone-holder '3 held in raised position above the drive-roll "-2 through the means of the ratchet-mechanism shown in Figs. 5 and .6, the machine is prepared for operation by placing a paper shell or tube T on the mandrel or holder. The strand 3/ .of yarn or thread is drawn up from its source of supply, not herein shown, and led under the breakage-1ever125,

thence across the upper edge of the --threa-dthe latter to hold lifter .65 and its. end secured to the cone- With the .machineat rest the parts :of the stopping-mechanism arein position s'ubstan- I itia' llyasshown in Fig.2. To start :the windingthe oneratorgrasps the startingdever 105 and presses ii t downwardly to the position illustrated in Fig. 4. This action rocks the frame i100, and the latter acts through its drawn back into the position shown in Fig.

4 so that the shoe 29 on thedog 43 is moved .back to clear the'ilower end of the:quadr'ant 30. As soon as the slide hasbeen withdrawn in this manner the further movement :of the rocking frame 100 causes its extension 108 to engage the :crook or crank '58 at the end of 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. 6, thereby causing the pin 4.7 .to act against the pawl .to release the flatter from :the teeth 49 :onthe quadrantc30. Immediatel-ythe pawl 50 is released the arm 10 will swing downwardly'ito lower the coneholder 3 to bring the surface of the coptube carried thereon into contact with the periphery of :the continuously rotating dTdVBfl'Oll 2-. The contact of the cop-"tube with the drive-roll will therefore cause the cop-holder .tobe rotated therefrom in the die rection indicated by the arrow in Fig. 4." As the cone-h-olderlis lowered against the driveroll 2 the quadrant 8O slides downfiinto position to adapt :the shoe-29 on the dog '43 to 1 r be frictionally engaged with its convex .Surface after .the slide 35 has beenreleased to allow it to slide rearwardlyunder the action of its spring 45. This release ofthe slide 35 does not take place', however, until the starting-lever has been released by the .joperator. [Previous to this release of the sl de, 35 the downward movement of the .lever- 105, and the rocking action of the frame 100 ,causedthereby, acts through the bell-crank lever to cause the arm of the latter 'topressthe, tail 86 of theil'ever .87 downwardly to remove it from possible contact with the toothed wheel 95. "This ac- 'tionof the bell-crank lever 115 thus serves to prevent unwarranted arrest'of the windmg operation .whi'le the strand y of thread or yarn is slack and the breakage-lever dropped so that it will not free the lever 87 ,or, in other words,lower it away from the toothed wheel 95.

Itshould be stated that when the thread lifter 65 is first tilted or rocked upwardlythrough the action of the lever 90 it is held inthis position as shown in Fig. 2 by means "of the blade 60 of the detent'rod 5,6 which slides alongthe iilclined edge 64 of the detent p1ate62to the position shown in dotted into the position shown in Fig. 4 under the action of gravity. At this point the blade 60 on the detent-rod 56 is carried into engagement with the detentsl1oulder 61 on the plate 62, see full lines in Fig. 8, and this action causes the stopping-mechanism to be locked in inoperative position. The

' .dropping of the thread-lifter 65 permits the strandy of thread or yarn to ride across its upper edge in such relation to the thread guide 4 that it will be picked up by the guide to seat it in the groove 28 as shown in Fig. 1. This automatic threading of the thread- .guide takes place as the guide recipro-cates across the path of the thread in the manner as explained in the patent before referred to. Asthe strand 3 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 knock-off lever 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 position as shown in Fig.1 under the action of its spring 111. With the parts of the mechanism set in this relation the winding opera tion will continue with the threadguide 4 traversing the strand :1 back and forth lon- .gitudinally of the cone-holder 3 to direct it onto the cop-tube T.

\Vhen the strand y breaks or its supply is exhausted the breakage-lever 125 drops and raises the tail 86 of the knock-off lever 87 into the position shown in Fig. 3 to operate the stoppinganechanism of the machine in the manner as previously explained. Likewise, when the cone reaches a predetermined diameter the stopping-mechanism low thedog of the rod will thereby act arm. 81 and link 85 to lift is released through the disengagement of the quadrant 30 from the shoe 29 on the dog 43 in. the manner as next explained. As the quadrant 30 is carried up with the arm 10 its end finally rides off. from the shoe 29 toal- 43 to rock on its fixed pivot 42. This permits the rod 35 to slide to the right under the action of its spring 4:5 as shown in Fig. 3 and the pin 80 at the opposite end through the slot 79 in thelever 77 to rock the elbow-shaped arm 78 of the latter upwardly. The lever 77 isthus caused to act through the crank Y the tail 86 of the knock-off lever 87 to bring it into position to be engaged by the teeth on the wheel 95. The rotation of the wheel 95 will therefore cause the knock-off lever 87 to rock the lever 90, acting through the tailpiece 93 on the thread-lifter to tilt the latter up wardly to withdraw the strand 3/ of thread or yarn from the tl'iread-guide 1.

As before explained, 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 of the spring 67 connected to the lever 52. The rocking of the lever 52 acts through the pawl 50 to force the quadrant 30 upwardly, whereby the arm 10 is raised to lift the cone-holder 3 to remove the cop or cone from contact with the periphery of the drive-roll 2, as shown in Fig. 2. The rotation of the coneholder 3 is thus arrested and the strand y of yarn or thread released from the threadguide 4: so that the winding operation ceases until the stopping-mechanism is manually operated again in the manner as previously explained. It has been noted the the blade 60 on the rod 56 slides along the beveled edge of the detent-plate 62 to the position shown by dotted lines in Fig. 8 to act as a holding-means to maintain the thread-lifter 1n ra1sed position unt1l the winding operation is started again, and in this way the machine is maintained inoperative until prepared to wind again.

It has also been explained that after the slide has been moved to the right under the action of its spring 15 to arrest the operation of the machine, the slide is slid back again to tilt the lever 77 downwardly so as to remove the tail 86 on the lever 87 from contact with the stopping-Wheel 95. This last action is effected through the operation of the lever 128 on the cam-plate 131 as the rod 56 is rocked by the spring 67, after its blade 60 is released from the shoulder 61 vholder away from the driving-drum shall be properly regulated for the purpose described.

While the present improved controllingmeans and stopping-mechanism is herein shown and described as applied to use with a certain type of machine, and as embodied in preferred form or construction, it is to be understood, that various modifications may be made in the structure and arrange ment of the partsof the device without departingifrom the spirit or scope of the in,-

, vention. V
