WINDING iymcmzNn.

Application filed October so, 1922. s m No. 597,979.

To all whom it may concern: I Be it known that I, CARL A. BRINK, a citi zen of the United States, residing at Cranston, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Winding Machines, of which the following is a specification.

This invention relates to winding machines and consists of improvements in the means for controlling the operation of the same.

The principal object of the improvement is to provide a more convenient method of starting and stopping the winding operation whereby the operator is relieved fromfreac'hing for the controls and saved from other motions so that the piecing up of ends may ;be accomplished with less effort and more expeditiously-to increase the rate of produc-' through manipulation of the foot-control so that the winding operation may be started more promptly after the piecing up of the yarns.

Further objects of the lmprovement are set forth in the following specification which describes a preferred embodiment of the invention as illustrated in the accompanying drawings. In the drawings:

Fig. 1 is a: cross-sectional elevation of a r winding frame having a plurality of winding units mounted thereon, showing one form of the improved foot-control as .applied thereto; c

The present improvements are herein described and illustrated as applied'to use in connection with a frictionor drum-driven type of winding machine in which the cop is rotated from surface contact with the pelimited in-this respect as it may be adapted for othertypes'of winders having a positive drive for the package. 1

riphery of a drum or drive-roll; but it is to be understood that the invention is not Referring to Fig. 1 of the present draw- Y ings the windingmachine comprises, in general, a table or bed 2 supported from" suitable legs or standards 3 and mounting 'a double row of winding-heads or units 1-1 There may be any convenient number of winding-heads H spaced at intervals along the bed 2, but in Fig, 1, only, two of the opposite units, are illustrated. Each unit .which are embodied in box-like frames 4.

comprises, essentially, a constantly driven friction-drum or drive-roll 5, a pivoted frame 6 for rotatably supporting thespindle or mandrel T on. which the cop is wound, to adapt the latter to be held with its surface in contact with the periphery "offthe drive-roll 5; a helical cam 9, also continuously, driven; and a thread-guide 10 connected to be reciprocated from the camlongitudinally of the winding-mandrel to deposit the yarn .in cross-wound coils thereon.

The'above-named elements are common to practically all types of drum-winders 'and the drlvlng-connections foroperatlng the wmding-mechanlsm are not hereln shown or from overhanging arms 20 on the frame 4, an

of the. tube.

shown in Figs. 1 and 2. The outer ends of the arms 14 and 15 carry means for rotatably supporting the cop-tube or mandrel T on which the yarn or thread is wound, the tube consisting usually of a cylindrical billet of wood provided with an axial bore t; For this purpose-the arm '14 is provided with a bearing 21 in which is journaled a livespindle 22 having a reduced end 23 adapted to enter the end of the bore t in'the tube T. The spindle 22 carries a disk 24 pro vided with spurs 25 which engage a crossslot .9 on the end of the tube T to key the latter rotatively with the spindle. At the outer end of the opposite arm 15 is a similar live-spindle 26 journaled in a bearing at the extremity of a lever 27. The lever 27 is pivoted at 28 to the side of the arm 15 'so that it may be swung laterally in relation thereto to release the spindle 26 from the tube T, a spring 29 tending to normally maintain the spindle in place in the bore 2 Referring to Figs- 1 and 2, the frame 6 supports the mandrel or cop-tube T in position above the drive-roll 5 with the periphcry of the tube in contact with the surface of the roll so that it will be rotated therefrom to wind on the yarn. As the yarn is built up on the tube T and the cop increases in diameter the frame 6 will swing upwardly on its pivot 19. The movement of the tube T away from the drive-roll 5is controlled by suitable dogging-means which acts to prevent the return of the tube toward the roll after it has receded therefrom during the normal growth in the winding. The dogging-means is constructed and arranged as later described.

Pivoted on a stud 30 which projects from the side of the arm 14 of the frame 6'is a lever 31 having a curved arm 32 arched above the bearing 21. At the extremity of the arm 32 is a finger-piece 33 arranged opposite a finger-rest 34 projecting from the end of the arm 14. A spring 35 has its end hooked through a hole in the arm 32 of the lever- 31 and is anchored at the opposite end to a lug 36 rising from the top of the arm 14. The spring 35 tends to rock the lever 31in the direction indicated by the arrow 6, Fig.

2. and the finger-piece 33 and rest 34 may be explained. During the normal operation of v the machine the lever 31 is maintained in the position illustrated in Fig. 2 by means of a detent-rod 37 which holds it against the force of the spring 35. The rod 37 slides in a bearing 38 on the side of the arm 14 and is beveled off or pointedat its forward end to adapt it to engage a substantially V- shaped notch 39 at the end of a short arm 40 on the lever 31. Below the notch 39 the arm 40 terminates in a wedge-shaped toe 47, while above the notch the end of the arm is of arcuate shape to provide an eccentric cam-face 51 which serves a purpose as later explained. I

The opposite, inner end of the detent-rod 37 is bent at right-angles and hooked through a hole 41 in a sickle-shaped lever 42. The lever 42 is pivoted on a stud 43 held in a lug 44 rising from the rearward crossstrut 16 of the frame 6, and is controlled by a spring 45 anchored to the end of a curved lever 46 to be later described. The spring 45 tends to rock the lever 42 to urge the rod 37 into engagement with the notch 39 in the arm 40 of the lever 31. The sickle lever 42 depend-s from its pivot-pin 43'a-t the front of the rod 19 on which the frame 6 is hinged and reaches back in under'said rod in the curved portion 48 which terminates in a downwardly-extending straight arm 49. Threaded through the end of the arm 49 is a sizing screw 50 having a rounded end adapted to bear against the rearward side of the frame 4 on which the winding mechanism is mounted, see Fig. 2. The sizing screw 50 may be adjusted in the arm 49 of the lever 42 so that its end will contact with the frame 4 when the cop-supporting frame 6 has been rocked upwardly to a predetermined extent by the increase in diameter of "the winding; That is to say, the arrangement is such that when the package has reached a predetermined diameter the frame 6 will have been swung upwardly to such an extent that the screw 50 will be brought into contact with the frame 4 to rock the lever 42 in the direction indicated by the arrow 0 in Fig. 2. The rocking of the lever 42 in this manner will cause it to slide the detent-rod 37 to the left, as viewed in Fig. 2, g

2, the tension-device comprises opposite, piv

oted grids having fingers across which the yarn draws in a sinuous path; it being understood that when the machine is equipped for winding in multiple a plurality of the, tensions are employed, one foreach strand to be wound into the cop. Only'one of the tension-devices isherein illustrated, however, and the yarn leads upwardly therefrom to the guiding-slot in the reciprocable thread-guide 10 by which it is traversed on the cop C. Intermediate the tension-device and the thread-guide 10 is a wire breakagelever which is provided with opposite, parallel legs pivoted on a rod 61 extending between a pair of plates 62 projecting forwardly from the frame 4, see Fig. 2. 'The yarn 3 draws across a horizontal bar 63, which connects the upper ends of the legs of the breakage-lever 60, and normally maintains the lever in substantially erect position as illustrated inFig. 2. The lever 60 has a right-angled extension 65 at the'lower end of one of its legs which is inserted through-a loop 66 at the forward end-of a wire link 67 The opposite end" of the link 67 is hooked into a hole 68 on the elbow-shaped arm 69 of a pawl-lever 70. The pawl-lever 70, is pivoted on a pin71projecting' through the sides of a push-bar 72 which is connected at its rearward end to the sickle-shaped lever 42 for operating-the detent-rod 37 previously described. As shown in Fig. 2, the curved portion 18 of the lever 42 is provided on its side withan arcuate slot 7 4: which is engaged by a pin-or roller 75 carried at the rearward end of the ush-bar 72. The forward end of the pus bar 72 is supported from a. rockable arm 77 having a :pivotal connection with the bar at 78. The arm 77 below the pin 71 to an opposite arm formed with a toe 86. adapted to-be rocked into position to engage with the rounded teeth 87 on the interior of the rim of stopping-wheel 88, see Figs. 5 and 6. The wheel 88 is keyed to the shaft 89 which drives the traverse-cam 9, see Fig. i 2, and rotates continuously therewith during the operation of the machine. The pawl 70 and its'arm S5 are rocked from the link 67 through the connection of the latter with the breakage-lever 60 which is adapted to swing to the right, as i shown in Fig. 6, when released by the breaking of the yarn 3 drawing across its horizontal cross-bar 63.. A. finger 90 projecting from the arm 69 of the' pawl 70 is adapted to contact with thetop of the puslrbar 72 to limit the rocking movement of the pawl. Referring to 5, one of the legs of the breakage-lever 60 is formed with a U-shaped bend or crook 92 which is adapted to make contact with the end of a lug 93 projecting from'the upper end of the arm 77, which supports the outer end of the push-bar 72. Vhen the push-bar 7 2 has been carried into the position illustrated. in ig. 5, through the operation of the stopping-mechanism as later explained, the arm 77is rocked to depress its lug 93 to engage it with the crock 92 on the breakage-lever 60. This action causes the breakage-lever 60 to be rocked into vertical position and held there until the winding operation is started aga1n; it being observed that the engagement of the extension 65 on the le of the breaka e-lever 60 with the loop 66 on the link 67 permits a slight movement of the lever without rocking the pawl 70.

1 The arin 77 also hasa further function in operating the thread-bail 95 which lifts the yarn away from the thread-guide 10 upon lifter 95 consist-sof a narrow plate extending across the front of the machine in close association with the traverse-guide 10. The

forward edge of the lifter 95 is rolled over at 96 toadapt it to receive a suitable hinge-rod 97 pivotally mounted in ears98 which project upwardly from a front cover-plate 100 extending between the sides of the frame 1. Gn the under side of the lifter-plate- 95 is an car 101 provided with a hole for receiving the hooked end 102 of a rod 103. Referring to Fig. 5, the lower end of the rod 108 is connected to a hooked extension 104 by means of a turnbuckle 105 which is employed for adjusting the length of the twopart ro'd'. The hook 106 on the extension 104 is hooked through a hole in-the end of a finger 107 projecting from the side-of the arm- 77. hen the arm 77 is rocked into the position illustrated in Fig. 5,'during the action of the stopping-mechanism of the machine, the connecting-rod 103101 will be pushed upwardly to raise the forward end of the thread-lifter 95 to lift theyarn y out of the slot in the traverse-guide 10 in the ,of the iniproverd foot-control willnow be describedin detail. Referring particularly to Figs. land 5, the arm 40Jof the lever 31,

which is pivoted on the. frame 6, is formed with an abutment on its side providing a bearing for a right-angled rod 111 inserted through a hole 112 at its end. One arm of the rod 111 projects downwardly from the bearing in the form of a pawl 114 which is provided at its end with a sharpened toe 115 adapted to engage with the ratchet teeth 116 of an arcuate rack or quadrant 117. The quadrant 117 has a fixed relation tothe frame 6 and, as herein shown, is constructed as a part of the machine frame 4. The rod 111 for the pawl 114 is held in its bearing in thearm 40 of the lever 31 by means of a cotter-pin 118 inserted through a hole in its end. A spring 120 is hooked through the lower, looped end of the pin 118 and anchored at its opposite end to a web 121 pr0- jecting from the side of a finger 122 on the lever 31. The spring 120 acts to rock the pawl 114 to carry its toe 115 toward the teeth 116 on the quadrant 117 and the upper end of the pin 118 is adapted to contact with a pin 123 driven into the side of the arm 40 to limit the rocking movement of the pawl. The engagement of the pin 118 with the stop-pin 123 acts to hold the pawl 114 normally just clear of the teeth 116 on the quadrant 117. It will be obvious from the above description that when the detent rod 37 is released from the lever 31 and said lever rocked under the force of its spring 35, as shown in Fig. 5, the pawl 114 will first he carried into engagement with the teeth 116 to then operate with a toggle-action to raise the frame 6 to lift the cop off from its drive roll in the manner as more fully explained hereinafter. It is also to be noted that the downwardly extending finger 122 on the lever 31 is formed with a lug or abutment 125, shown in dotted lines in Fig. 5, which is adapted to strike against a projection 126 on the frame 6 to limit the rocking action of the lever 31.

It has been explained that during the winding of the cop the frame 6 is swung upwardly as the package grows in diameter, and to control this movement of the copcarrying frame it has been found expedient to employ a dogging-means as neXt described: Referring to Fig. 4, the dogging means consists in an elbow-shaped arm 130 provided with a bearing-rod or shaft 131 pivotally mounted in an arm or extension 13 on the under side of the cross-strut 17 of the frame 6. The arm or dog 130 is beveled 05 on its sides at 135 to provide a wedge-shaped section which engages with a tapered or V -shapec groove 136 out into the side of the quadrant 117. The lever 46, previously referred to, has its hub secured to the bearing rod 131 of the dog 130 by means of a set-screw 137 and it will thus be seen that the spring 45 which connects the lever 46 with the lever 42 will act to normally and grooved quadrant, is well known in the art. Referring now to Fig. 4, the controlling-lever 46 for the dog 130 is provided with a forwardly-extending arm 140 having its end beveled ed to form an inclined face 141 which is adapted to'be engaged by the lower rounded end of the finger 122 on the lever 31. Through thisarrangement the finger 122 is caused to rock the lever 46 to release the dog 130 from the quadrant 117 when the lever. 31 is depressed at its forward end, either manually or through the action of the foot-control as later explained.

The means for operating the stopping lever 31 and its related mechanism from the foot-control is arranged as next described: Referring to Figs. 3, 4 and 5, on the crossst-rut 17 of the frame 6 is a bearing 142 in which is pivotally mounted a rod 143 formed with a right-angled arm 145 at one end. Hooked into a hole at the'outer end of the arm 145 is a link 146 which is pivotally connected at its opposite end to the arm 40 of the lever 31. On the opposite end of the rod 143 from the arm 145 is'a lever- 15() secured fast thereto by a binder-screw 151. The lever 150 is provided with two holes 152 and 153, either one of which is adapted to receive the hooked end of a wire rod or link 154. Referring now to Fig. 1, the lower end of the link 154 is hooked into the upper'end of a rod 155 which reaches down'to a foot lever or treadle 156. In the present type of machine shown in Fig. 1 an individual footlever is provided for each single unit or winding-head on the frame 2 and the levers for opposite units project outwardly from a central horizontal shaft 157 on which the series of levers are pivoted. The shaft 157 is held in bearings on the legs or standards 3 which support the frame 2 at its opposite ends. Each foot-lever or treadle 156 is provided on its side with 'a projecting rib or plate 159 formed with a series of holes 160 into which the lower end of the rod 155 may be hooked. By adjusting the rod 155 in the different holes in the rib 159 the height of the treadle maybe varied in accordance with requirements of its operation.

Having now described the structure and arrangement of the essential parts of the machine its method of operation will next be explained; Fig. 2 of the drawings illustrates the parts of the winder in the position they assume substantially at the start of the winding operation. The winding mandrel or coptube T is shown as having a slight amount of yarn wound on its exterior, the first layers of the package C whose surface is held in contact with the periphery of the driveroll 5 under the weight of the pivoted supportingrf-rame; 6. As-illustratedin Fig. 1, the yarn y leads up from the supply-bobbin B through the tension device 54, thence across the upper bar 63 of the breakagelever 60, and through the eye or notch. in the traverse-guide 10 to the package C. The package or cop; C is rotated through its sur- -face contact with the continuously driven drive-roll 5 and the continuously reciprocating traverse-guide 1O traverses the yarn g back and forth to depositit in helical coils which formthe layers of the cop. As the winding increases in diameter with each added layer of yarn the frame 6 is swung gradually upward and the dogging-device 130 acts frictionally on the quadrant 117 to prevent retrogressive movement of the frame whereby .to eliminate vibration of the package on the drive-rolh It has been explained that during the normal operation of the machine the breakagelever 60- is maintained in erect position by the traveling yarn y leading across its upper bar 63. lVhen the yarn y breaks or becomes exhausted at its source of supply, however, the lever 60 will be released and, acting under the force of gravity, will tilt forward into the position shown at the right in Fig. 1. As illustrated more in detail in Fig. 6, this forward rocking movement of the lever 60 causesits projection 65 to be swung back in the directionindicated by the arrow 6. to act through the link 67 to rock the pawl-lever 70, whereby to raise its toe 86 into position to be engaged by one of the teeth 87 on the stop-wheel 88. The wheel 88 is continuously rotated in the direction indicated by the arrow f in Figs. 2 and 6, and as the stop-finger 90 on the pawl-lever 7 O is brought down against the top of the push-bar 72 the dogging of the pawl on the rim of the wheelwill act to slide the push bar rearwardly or in the direction indicated by the arrow 9 in Fig. 6. As before noted, the opposite end of the push-bar 72 is connected to the detent-lever 42 by means of its roller 75 which rides in the arcuate slot 74 in the arm 48 of said lever as the frame 6 swings upwardly. It will therefore be seen that in whatever position the frame 6 may be the rearward movement of the bar 72 will cause the lever 42 to be rocked in the direction indicated by the arrow 0 in- Fig. 2. This movement of the lever 42 acts to slide the detent-rod 37, which is connected therewith to release its end from the notch 39 in the arm 40 of the lever 31. Upon the releaseof the lever 31 in this manner its spring 35 will cause it to be rocked in the direction indicated by the arrow 7) in Fig. 2 until the abutment on its finger 122 brings up against the projection 126 on the under side of the arm 14 of the frame 6, see Fig. 5. As the arm 40 of the lever is rocked downwardly it carries the pawl 114 into enor jumping rantEll7; and operates with a toggle action to .ga-gement with the teeth, 116 on the quad:

liftthe frame 6,.whereby the surface of; the 7 Cop G israi'sed away from the peripheryof the driver-0115, as shiowll in Fig. 5,.[ I

The withdrawal of the cop from contact with the drive-roll serves to arrestitsv rotation and meanwhile the yarn y, is raised out from the slot in the thread-guidell) by the thread-lifter 95., This latter action is effected by the raising of the rod 1034104 under the rocking; motion of the armf77 which is; connected to the push-bar 72, and moved therefrom in the manner asv later exjplained. Through the above-describedseqnence of operations, the winding; is arrested and the cop held in raised'position above; the dri-ve roll until the operator pieces up the yarn.

It. will be observed by reference to Fig.

'5 that-as the arm 40 of the lever 31 is rockeddownwa-rdly the end of the detentpivot 30 of the lever 31 causes the rod 37 to be slid farther back against the pressure of its. spring 45 to. rock the lever '42gto such an extent that it will draw the push-bar '72 rearwardly to. remove the pawl-lever 70 from proximitywiththe rim of the stop-wheel 88. In this manner thetoe 8.6; on the pawllever 7 O is withdrawn from engagementwith the teeth 87 on the wheel to prevent chattering or jumping of the pawl as the wheel continues 'to rotate. The. rearward movement of the push-bar 72 also serves to rock the arm 77 into the position illustrated in Fig. 5 tov raise the thread-lifter 95 as before explained and also to depress the lug 93. on the arm into engagement with the crook .92 on the breakage-lever 60. to return the latter to erect position. i e

In preparing the machine for operation the operator employs both hands for piecing up the ends and with the present improved arrangement: of the controlling means no hand motions arerequired for starting the machine. The loose end on the cop-is drawn off and pieced'to the end from the supply bobbin and the free length of yarn, held across the hand in order that it may feed properly into the machine without snarling or tangling. As soon as the ends of the yarn are tied or spliced the operator presses with the foot on. the treadl'e 156 and this action returns the 'partsvof the machine to operative position again tocontinue the winding of the cop. in the manner as next explained:

As the foot-lever I through the rods 1 55 and 154 to rock the lever downwardly wherebyv the rod 143 is turned to raise its crank arm 145,, as shown in Fig. 4. The arm 145, acts through the link 146 to raise the arm 40 ,of the lever: 31

I to release the pawl 114 from the teeth on the quadrant 117, and the continued raising of the arm 40 also serves to release the dog 130 from the quadrant. This latter action is effected by the engagement of the lower rounded end of the finger 122 with the beveled face 141 of the arm 140 on the lever 46 which rocks the latter againstthe force of the spring 45. Asso'on as the pawl 114 and dog 130 have been released from the quadrant 117 in this manner the pressure of the foot on the treadle 156 is released slightly and the frame 6 is thus allowed to drop slowly under the action of gravity to permitthe cop C to be brought gently into contact with the periphery of the driveroll 5. i

It will be noted by reference to Fig. 4 of the drawings that as the lever 150 is swung downwardly by the action of the depressing of the treadle 156 it strikes against the rearward cross-bar 16 of the frame6 so that the downward movement of the frame is maintained under the control of the operators foot pressure. It is to be further observed that the full movement of the lever 150' serves to rock the connected lever 31 farther than necessary to engage the detentrod 37 with the notch 39 in the arm 40. That is to say as the arm 40 of the lever 81 isv rocked upwardly its toe 47 comes against the pointed end of the detent-rod 87 and holds the latter in position to prevent the chattering or jumping as the wheel rotates.

Furthermore the bar 72 when in this position as illustrated in Fig. 5 serves to hold the lever 77 with its lug 93 rocked downwardly in engagement with the crook 92 on the breakage-lever 60, as before explained. The breakage-lever is thus held in erect position until the yarn can be released from the operators hand and allowed to draw across its bar 63.- Through this arrangement the breakage-lever 60 is prevented from dropping to stop the winding operation as long as the operators foot is held on the treadle so that the starting of the machine is accomplished without danger of premature stopping before the yarn is replaced in contact with the breakage-lever. After the operator has observed that the machine is operating properly the foot is removed from the treadle 156 and the lever 150 is then allowed to rock back to neutral position with the notch 39 in its arm 40 engaged by the detent-rod 87, as shown in Fig. 2. The parts of the stopping-mechanism will thus be returned toand maintained in inoperative relation ready to become active again upon the breakage of the yarn. i

It will be observed by reference to Fig. 5 that when the winding is arrested the windinginanclrel T is raised above the drive-roll 5 to a sufficient extent to give free access to the whole surface of the cop C so that the operator may readily discover and 'pick up the broken end of the yarn. Should it be required to lift the cop still farther this may be accomplished by pressing on the treadle 156 to draw the lever 150 down against the cross-strut 16'of the frame 6, see Fig. 4, when the lever 150 will act to rock the frame 6 upwardly on its pivot 19. It will thusbe seen that with the connecting rod 154 ongaged with the hole 153 at the end of the lever 150 the foot-lever or treadle 156 may be employed to either raise the cop from or lower it into contact with the drive-roll. In this way the winding machine is rendered completely under the control of the footlever so that the operators hands are left entirely free for other duties. In some cases where it may not be desired to lift the cop from the drive-roll under foot-control the rod 154 is hooked into the hole 152 in the lever 150. With this latter arrangement the lever 150 will be operated from the treadle 156 inthe same manner as previously explained to release the pawl 114, and continued pressure on the treadle will draw the frame 6 downwardly to effect a more prompt return of the cop into driving contact with the roll 5.

It will be evident from the foregoing that the present improvement provides a much more convenient and expeditious method of controlling the operation of the winding machine than the usual hand-control. With the present foot-control both of the operators hands are left free to piece up broken ends so that the winding operation may be started the instant the splicing is completed without waiting to reach for a hand-lever. Furthermore, the operator is not required-to reach in across the cop to grasp the starting lever and this is a most important improvement from a practical standpoint. Usually the operator breaks or'cuts ofi the waste ends of yarn left extending from the knotand holds them in the fingers while starting the machine. With the usual arrangement of starting-mechanism it is necessary to reach above the cop to grasp the starting lever and ithas been found in practice that the bits of yarn in the operators fingers will often be caught up anddrawn into the package. If not discovered and removedthese loose ends in the cop will be drawn into the twister, doubler or other machine to which the package ultimately delivers its supply and the product of such machine will show faults from the loose ends corkscrewingor bunching with the other strands. .Inother cases the waste yarn will be caught in the going parts of the machine Where it is liable to cause improper functioning of the mechanism and damage to its parts.

' \Vith the present improved arrangement of the controls the operator is not required to reach or OtllGI'WlSB'GXQI't himself in starting the machine; hence an erect position may be maintained which greatly reduces'fatigue and lessensthe labor of the operator whereby greater productivity is accomplished.

,Furthermore, the product is improvedand the capacity of the machine increased due to shorter periods ofstopping.

I'Vhile I have herein shown and described a preferred construction of my improved control-device as applied to a certain type of machine it isobvious that modifications in structure and arrangement and different methods of adapting it for usemay be made which would fall within the spirit and scope of the present invention. Therefore, without limitation in this respect, I claim:
