This invention'relates to improvements in winding machines and particularly to machines of that type known as friction-driven or drum winders in which the cop or package is rotated through contact with a continuously driven drive-roll or drum. The present improvement relates to braking means for checking the rotation of the cop or package when the latter is removed from contact with the drive-roll or drum to arrest the winding operation. v a

A principal object ofthe invention is to provide means for promptly arresting the rotation of the cop or package to prevent it from turning under momentum after it is withdrawn from driving contact with the turned or rotated manually to find a broken end or for other purposes. 1

Another object of the invention is to provide braking means which is automatically released when the winding-spindle is thrown out of operative position to doff a full cop or package and forth in the following specifications which describes a preferred form of construction of the invention, by way of example only, as illustrated by the accompanying drawings.

Referring first to Fig. 1 of the drawings, the winding machine herein illustrated is similar in general'to that shown and described in United States Letters Patent No. 1,656,088 granted January 10, 1-928. Winding machines of the resent type are usually constructed in gang orm with a plurality of winding units arranged in series along a common frame or bed. As all of the units are of the same construction and arrangement, how.-

ever, only one winding-mechanism is herein shown and described. In Fig. 1,: 2 designates one of the cross-frames or supports for the various elements of the winding mechanism and 3 is the horizontal drive-roll shaftwhich is journalled in suitable bearings 4 on the cross-frames. ously driven and carries a series of driverolls or drums 5 for rotating the cops or packages C as they are wound.- A continu- The shaft 3 is continuously rotated cam-shaft 6 extends parallel with and below the drive-roll shaft 3, being journalled in suitable bearings 7, also supported from the frame members 2. v

The cam-shaft 6 carries one or a series of cylindrical cams 10 for reciprocating the traversing thread-guides 11 which depositgthe turns of winding in place on the cops or packages. As herein shown a separate cam is provided for each winding unit, the cam through which extends a screw or stud 16 forming the bearing for the bowl or roller 13. The thread-guide 11 reaches upwardly from the rod 14 and is provided with a head 17 formed with a thread-groove or slot:

through which the strand y ofv yarn, thread or other material feeds to direct it to the winding. A horizontal bar 18 arranged above the rod 14 is engaged by a forked bearing 19 on the back of the thread-guide 11 to support the latter in position with its head 17 in close relation to the point of contact of the ackage on the drive-roll 5.

T e cop or package C is wound on a suitable container or carrier which may consist of a aper. tube ora wooden core T shown in detai in Fig. 4 as rotatably supported on the winding-spindle 20. The wlnding-spindle 20 is carried at the outer end of a swlnging arm 21 which'is pivoted to rock on a horizontal rod 22 supported from bearings 23 on the cross-frames 2. As herein illustrated the arm 21 terminates in a horizontal rod or stud 24 on which is held the support or mounting 25 for the winding-spindle 20. Referring to Figs. 2 and 3of the drawings, the mounting 25'isconstituted by a hub 26 clamped to the rod 24 by a bolt 27 and provided with a forwardly extending arm 2,8 to which is swiveled the spindle-support 30. The spindle-support 30 comprises a hub 31 abutting the under side of a boss 32 on the arm 28 and having a bolt or stud 33 extending through a central hole in the boss. A nut 34 and check-nut 35 are screwed on to the end of the bolt 33 abutting a washer 36 to hold the support 30 in place while adapting it to turn or swivel with respect to its mounting 25. t

The winding-spindle 20 projects forwardly from the support 30, being made integral therewith or suitably attached thereto at its rearward end, see Fig. 4. The spindle 20 is normally held in parallel relation with the hub 26, see Fig 1.

axis of the drive-roll 5 by means of a detentlatch 37 which permits it to be swung laterally by turning the support 80 on its swiveled bearing in the arm 28. The detent-latch 37 consists of a flat leaf spring fastened to the back of an arm 88 depending from the The latch 37 is fastened to the arm 38 by a bolt 39 and held. from turning thereon by a dowel pin 40 engaging a slot 41 in its end. The free end of the latch 37 is bent around to form a detent pro 'ection or catch 42 adapted to spring into a shaped notch 43 on the rearward side of the spindle-support 30, see Fig. 4. When the spindle 20 is swung outwardly as shown in Fig. 7, to facilitate the dofling of the completed cop or package and the placing of a new tube thereon, the detent-eatch 42 is sprung out of the notch 43 and rides over onto the flat'face 44 of the support 30 to hold thes'p'indle in this position.

The butt end of the spindle 20 is formed with an enlarged bearing 45 on which is retatably mounted a flanged wheel constituting the brake-drum for controlling the rotation of the cop-tube or carrier T. The coptube T, herein illustrated in the form of a wooden or fiber cylinder, is bored axially to adapt it to be slid onto the spindle 20 to support it rotatively therefrom. A usual form of spring-operated latch 46 is swiveled in aslot 47 on the outer end of the spindle 20 to adapt it to be turned into the position shown in Fig. 4 to retain the tube in place; and to release the tube the latch is turned into the position illustrated in Fig. 7. The wheel or brake-drum 50 is provided on its forward face with one or more radial splines 51 adapted to engage a suitable cross-slot t in the end of the tube T to connect the latter rotativelv therewith. The brake-drum 50 has a hub 52 rotatable on the enlarged portion 45 of the spindle 20 with its endabutting the side of the support 30, the drum being held in place by means of a washer 53 forced onto the spindle and received in a recess 54 at the front of the brake-drum.

The brake-drum 50 has a cylindrical flanged rim 55, the interior of which is adapted to be engaged by a friction brake-band 56 shown in detail in Figs. 2, 3 and 4. The brake-band 56 is of the split type and has a supporting hub or bearing 57 held on a headed pin 58 driven into the side of a lug 59 on the support 30. Opposite its bearing 57 the brake-band 56 is formed with a parallel-sided-opening 60 to adapt it to be expanded. Projecting into the opening 60 is a pin 61 having a flat-sided end portion 62 which serves as a cam for springing the ends of the band apart to cause it to be expanded to frictionally engage the interior of the flange 55. The pin 61 is journalled in a yoke shaped bearing63 on the side of "the support 30, see Fig.4, and carries a crank-arm 65 by means of which it is turned to cause its fiatted cam )ortion 62 to expand the brake-band 56. The brake-arm 65 has a hub 64 received be llfi tween the sides of the bearin 63 and fiXtdlf 68 is clamped in place against the side of the arm 65 by means of a nut 69 on the stud 67 and by releasing the nut the bushing maybe ,screwed into the hub, see Fig. 4. At one side of its pivot the lever 7 O is forked to provide a slot or opening 73 which engages with the eccentric bushing 68 on the brake-arm 65. From its forked portion the lever 70 extends upwardly above the brake-drum 50 in an arm .74 which is provided at its end with a rectangular. opening 75. Referring particularly to Figs. 5 and 6, a flat cam-plate or blade 76 projects from'the side of a fingerlever 77 through the opening 75 and is formed with beveled edges 78 adapted to frictionally engage the sides thereof. The bevels 78 on the sides of the cam-plate 76 provide sharp edges to secure this frictional engagement while permitting the plate to be turned in the slot 75. The finger-lever 77 is carried at the end of a pin or stud 79 journalled in a hearing 80 at the end of the arm 28. It will be observed by referenceto Fig. 3 that when the lever 70 is rocked to carry its forked portion downwardly the cam 62 will be turned to expand the brake-band 56 to effect the braking lever, will act on the sides of the opening 75 action. The'fingerdever 77 is provided for the purpose of releasing the brake after the rotation of the cophas been once arrested, it being here noted that when the lever 77 is rocked upwardly into the position shown in Fig. 5 the edges of the cam-plate 76, which latter is disposed eccentric to the pivot of the to rock the arm 74 upwardly. This causes the forked portion of the lever 70 to be raised to lift the brake-arm 'and thereby turn the cam 62 into neutral position as. shown in Fig. 5. K v

The brake-actuating lever is operated automatically to effect the braking action through pawl and ratchet mechanism illustrated in Figs. 1, 2, 3 and 8. These devices form apart of the stopping-mechanism of the winding machine and will be next de It will .be understood that thescribed. start of the winding operation the periphcry of the cop-tube or carrier T rests upon the surface of the drive-roll ,5, and as the yarn or other strand inaterial is wound onto the tube the growth of the cop being built .will cause the tube to be moved upwardly away from the drive-roll. Thus, as the coptube T rotates on the winding-spindle 20 the growin mass of yarn causes the spindle to recede rom the drive-roll with its supporting arm 21 swinging upwardly abTout its.

axis on the rod 22. Dogging means are usu-' ally provided to prevent the winding-spindle from moving toward the drive-roll after it has once been lifted by the growth in the winding so as to check any tendency of the package to vibrate or jump up and down. A preferredform' of dogging-mechanism is shown in Fig. 1 as comprising-an arcuate quadrant 83 fixedly attached to and depending from the cop-supporting arm 21. The

quadrant 83 is disposed substantially conof the arm 21. The dog 84 is manually released from the quadrant 83 to permit the return of the cop into driving contact with the drive-roll to start the winding operation after it has been arrested, but the means for effecting this action have no relation to the present invention and are therefore not herein described.

The main element for actuatin the lifting means to remove the cop from riving contact with the drive-roll consists in a rockable rod 87, shown in Fig. 1 as being mounted in bearings on the cross-frame 2. Referring further to Figs. 2, 3 and Si the rod 87 carries a lever 88 on its rearward end secured fast thereto by a set-screw 89 or by other suitable means. The'lever 88 has a horizontal arm 90 to which is connected a coil spring 91 anchored at its lower end to the framemember 2 as shown in Fig. 1. The spring 91 tends to rock the lever 88 in the direction indicated by the arrows in'Fig. 8, but during the normal operation of the machine such rocking action is prevented by detent-means theblade 93 on the end of the rod 87 through 3, 0

suitable instrumentalities, not herein shown my described in detail as they may be of prior usual construction as illustrated in the paten hereinbefore referred to- Referring now to F gs. 2, 3 and 8, the lever 88 has an arm 97 extending -in'opposite relation'to its arm 90 and carryin an upright pawl 98. The upper sharpene end of the pawl 98 is adapted to engage with a series of ratchet teeth 99 formed on the side of a curved extension 100 depending from the rearward arm' of the brake-actuating lever 70. The pawl 98 is pivoted on the arm 97 of the lever 88 through a pin-andslot connection indicated at 101 in Fig. 8. Projecting radially from the pivoted end of the pawl 98 is a toe 102 which is engaged by a plunger 103 slidable in a bearing 104 on the arm 97 and-urged upwardly by a pocketed spring 105. The spring 105 acts through the plunger 103 to maintain the pawl 98 in engagement with the ratchet on the arm 100 and the pin-andslot connection at 101 permits the pawl to follow the'teeth as the ratchet extension 100 moves upwardly with the arm 21 carrying the winding-spindle whereby to guard against the pawl resting on the points of the teeth. The arm 97 of the lever 88 carries a pin 106 adapted to engage the side of the pawl 98 to release its end from the ratchet 100 when the lever 88 is rocked in the direction opposite to that indicated by the arrows in Fig. 8. It will be understood that when the lever 88 is rocked under the action of the spring 91 the pawl 98 will be moved bodily upward to lift the ratchet extension 100, this action first rocking the brake-lever 70 to operate the braking means; and the continued movement of the pawl operating to swing the arm 21 bodily upward to raise the cop C off from the drive-roll 5. The operation of the complete machine is as next more fully ex lained.

process the machine for winding the pawl 98 is released from the ratchet-member 100 by turning the rod 87 in the direction opposite to that indicated by the arrows in Fig. 8, the pin 106 on the lever 88 bein thereby caused to enga e the side of the paw to effect itsrelease. e rod 87 is operated in this manner through the means of a manuallycontrolled starting-lever not herein shown and described, but which may be of the general arrangement as illustrated in the prior patent h'ereinbefore referred to. The startinglever also acts to slide'the rod 85 to release the dog 84 from the quadrant 83 and when this double release is elfected the arm 21 is allowed to swing downwardly to carr the co -holder or tube T into contact wit the drive-r0115.

The strand 3 of yarn, thread or other material is led from its source of supply, not herein shown, through the slot or groove in the thread-guide 11 and its end attached to the tube T. As the machine starts to operate the starting-lever is released to permit the dog 84 to return into engagement with the quadrant 83 and meanwhile the rocking of the rod 87 has engaged its end 93 with.

the detent-shoulder 94 on the plate 95 to maintain the lever 88 in position with the pawl 98 engaging the toothed side of the ratchet 100. The contact of the tube T with the periphery of the drive-roll causes the tube to be rotated the spindle towind on the yarna'nd the thread guide 11, which is continuousl reciprocated from the cam 10, traverses t e strand y longitudinally of the tube. As the winding builds upon the tube T with winding-spindle 20 recedes from the drive-roll 5 with its supporting arm 21 swinging upwardly about its pivot 22. During this movement of the winding-spindle away from the drive-roll the dog 84 acts in the manner as before explained to check retrog'ressive movement of the arm 21 and the pawl 98 maintains a step-by-step engagement with the teeth 99 on the ratchet 100.

The winding machine is usually provided with automatically-operated instrumentalities, not herein shown, for arresting the winding operation when the yarn breaks or runs out and also upon the completion of the packs age to a predetermined'size. These instrumentalities act to release the blade98 on the rod 87 from the detent-element 95, whereby the spring 91 is ener ized to rock the lever 88 in the direction indicated by the arrows in Fig. 8. This rocking action of the lever 88 causes the pawl 98 to act on the ratchet 100 to raise the arm 21 bodily to lift the co or package C away from the drive-roll 5. uring this lifting action on the arm 21 the pawl 98 forces the ratchet 100 upwardly to rock the brake-lever 70 on its pivot 72. As the lever 70 is rocked upwardly in this manner its iorked portion is carried downwardly to depress the outer end of the brake-arm 65.

That is to say, the slot 7 3 in the lever 70 acts on the eccentric bushing 68 to press the brakearm 65 downwardly as shown in Fig. 3 and the cam portion 62 of the pin 61 is thereby turned in the opening 60 between theopposite ends of the brake-band 56. The brake-band 56 is thus expanded to cause it to frictionally grip the interior of the flange 55 on the bral're-drum 50 which, as before explained, is rotatively connected with the cop-tube T. The brake is therefore applied simultaneously with the removal of the cop or package from contact with the drive-roll so that the rotation of the package is instantly arrested. To insure this action of the braking-means instantaneously with the withdrawal of the package. from the drive-roll the connection between the brake-lever 70 and brake-arm 65 may be adjusted with minute accuracy by turning the eccentric bushing 68 on the stud 67 in the manner as before explained.

After the cop or package has been raised away from the drive-roll and its rotation arrested the brake may be released to permit turning the cop on the winding-spindle 20 so as-t o find the broken end or for other purposes. This is especially desirable when doubling the yarns in the package, that is in winding several ends up. When a plurality oiiyarns are delivering to the package the breakage of any one will cause the stopping of the winding, but it is difiicult to find the broken end which adheres to the package unless the cop can be turned or rotated on the winding-spindle. The manual release of the brake for this purpose is readily accomplished by turning the finger-lever 77 up wardly as shown in Fig. 5 to cause its eccentrio cam-plate 7 6 to raise the arm 74 of the lever 70. This shifts the brake-arm 65 into neutralposition to turn thecam 62 toallow contract-ion of the brake-band 56.

After the brake has been released under operation of the lever 77 the cam-plate 76 continues to hold it released while the'arm 70 is under pressure of the pawl 98 in maintaining the arm 21 in raised position. When,-

however, the pawl 98 is disengaged from the ratchet 100 to allow the package to drop back into contact with the drive-roll 5 the pressure on the lever 70 isrelieved and the frictional grip of the cam-plate 76 on the sides of the opening 75 in the arm 74 of the lever 70 is released so that the finger-lever 77 drops back into first position, as shown in Figs. 2 and 3. Through this provision the lever 77 is automatically returned to inoperative position to release the brake-lever 70 for subsequent action after the package has been returned into driving contact with the roll 5 to again start the winding operation.-

When the winding of the cop or package has been completed and the cop raised away from the drive-roll as shown in Fig. 3 of the drawings the operation of dofiing'the cop is facilitated by swinging the winding-spindle 20 forwardly toward the front of the ma- 1 chine. As the spindle 20 is swung out into this position as shown in It ig. 7 the detentlatch 37 is released in the manner as before explained andthe brake-arm 65 is simultaneously disconnected from the brake-lever 70. In this way the brake is released so that afterthe full cop has been dofied a new coptube can-be more conveniently placed on the spindle '20 and connected with the brake-drum 50. After the new tube has been applied to' Y the spindle with the splines 51 on the brake drum engaging its cross-slot t the latch 46 is turned into position to hold it in place andthe spindle is then swung back into operative relationship with the drive-roll. I As the spindle is swung back to engage the de tent-latch 37 with the notch 43 in the support 30 the bushing 68 on the stud 67 is carried into the slot 73 in the lever to again connect the parts for automatic operation.

It will be observedfrom the foregoing that my improvement provides a particularly simple and eflicient braking means for arresting the rotatior of the cop or package as it is withdrawn from driving contact with the drive'roll or drum.. The braking device is operated directly from the stoppingmechanism of the machine to arrest the to understood. that various modifications may be made in the structure and arrangement of its parts without departing from the spirit or scope of the invention.
