12 Claims.

The invention pertains to a bunch builder at tachment for winding machines andthe like. The object of the invention is to provide an improved type of bunch builder mechanism for 10- c'ating upon a bobbin a bunch preliminary to progressive winding thereon; also to provide a bunch builder mechanism by which a controllable time limitation may be-obtained for the wind forming the bunch, and which may be varied as occasion requires; and a bunch building mechanism, also, which permits of the length of the bunch being varied as may be desired.

It is a further object of the invention to provide a bunch builder mechanism as an attachment especially for the automatic winding machine which forms the subject matter of my pending application in the United States Patent Office, Serial No. 202,048, filed April 14, 1938, now Patent No. 2,247,718, July 1, 1941.

The invention can best be seen and understood by reference to. the drawings in which the builder mechanism is shown as applied to the machine, such portion only of the complete machine being shown as is necessary for a proper understanding of the invention.

portion of the clutch building mechof the machine. This box contains various drives,

and working parts relating to the bunch builder mechanism, as will afterwards be referred to.

Proceeding out of the gear box at the front are winding spindles 2 which are driven by mechanism within the gear box. These spindles co-operate with mechanism, not here shown but described in my said application, for holding the bobbins 3 during the winding operation, and from which the wound bobbins are released at the termination of the wind. Proceeding, also, from out of the front of the gear box, in determinate relation to the spindles and bobbins driven thereby, are traverse bars 4 on which are mounted carriers which bear the guides for the thread as it is wound upon the bobbins. Suitable bearings are provided for the ends of these bars. The traverse bars have both a rotary and reciprocative movement during the winding operation. They are rotated from oil gears 5 in the gear box and reciprocated from off a cam 6 within the same box.

Each traverse guide rod 4 is exteriorly threaded in part, and located on the part thus threaded is slidably arranged a thread guide carrier 8. Each of these carriers bears at the right and left two projecting thread eyelets 9, which extend over the positioned bobbins 3 and allow the thread to run onto the bobbins during the winding operation. The thread guide carrier has pivotally attached to it a thread carrying arm I l which is movable into and out of engagement with the threads on the traverse bar. When the arm is out of engagement with the traverse bar then the thread guide carrier may slide thereon. The arm I! of each thread guide carrier is positioned and controlled by means of a thread guide carrier release rod 2. As the position of this rod 12 is relatively changed, the thread carrying arm ll of the thread guide carrier will have engagement or disengagement with the threads on the traverse bar, engagement as the rod l2 is'moved down, i

and disengagement as the rod I2 is moved up. When the thread carrying arm ll of the thread guide carrier is in engagement with the threads on the traverse bar then the carrier and thread guides carried by it will be reciprocated by the reciprocation of the bar, and will have,'also, a progressive outward movement along the bar for 'sively on the traverse obtaining a progressive wind upon the bobbin.

the body of the thread guide carrier and at itsopposite end against an abutment it on the traverse bar. When the winding is initially started the thread guide carrier is then occupying a position in the vicinity of the gear nor; with bearing against a stop it adjustably mounted on the rod ill. The progressive winding of the bobbin will continue until the thread guide carrier engages a stop ll, when, through mechanism presently to be referred to, the thread guide carrier release rod it, which controls the position of the arm M, will be actuated to lift this arm into disengagement with respect to the threads on the traverse bar. Thereupon the return spring it on the traverse bar will return the thread guide carrier back to its initial position with bearing against the stop it.

The thread guide carrier release rods it are borne by crank arms it in which the opposite ends of the rods are arranged, and to which "they are fixed. All the crank arms are provided with axles it by which they may turn. The axles to the crank arms at the fore ends of the release rods turn within arms it on the frame of the machine. At the opposite ends of the release rods the axles of the crank arms turn within bearings on the front of the gear box, and one of these axles, or an axle it extends through its bearing into the interior of the gear box. Arranged upon the axle it, inside the gear box, are various parts of the bunch builder mechanism later to be referred to. The crank arms is are connected to turn in unison by a linkage 2i. When the crank arms are rocked in a clockwise direction as viewed from the front of the machine, the release rods lZ carried by them will be raised and will thereby release the arms ll of the'thread guide carriers for engagement with the threads of the traverse bars. Reversely, when the crank arms are rocked in an anti-clockwise direction the engagement between the arms M of the thread guide carriers and the threads of the traverse bars are restored. A rocking motion is imparted to the crank arms by a rock shaft 24. Thisshaft is mounted to rock within suitable bearings on the frame of the machine and is rocked back and forth in the operation of the machine at timed intervals, dependent upon the starting and completion of the wind. When the wind is completed and the thread guide carrier is brought into engagement with the stop ll, thereupon, in the operation of the machine the rock shaft will be turned in a clockwise direction. The rock shaft has secured to it downwardly extending lever arms iii-which turn as the rock shaft is turned. Pivotally connected to the ends of these lever arms is the linkage it which connectswith the crank arms l8. Consequently all the crank arms it will be .i lmed in a clockwise direction as the rock shaft 24- is turned in a clockwise direction; thereby elevating the thread guide carrier release rods i8 and moving the arms ll of the thread guide carriers into disengagement with the threads of the traverse bars. As the operation of the machine continues the spindles will be replenished with a fresh set of bobbins, the previously wound bobbins having been removed. Preliminary to starting the operation of the spindles and traverse bars, for winding the fresh set of bobbins, the rock shaft 2% will lti aaraoco in the operation of the machine be turned in an anti-clockwise direction and through the consequent reverse turning of the crank arms it will allow engagement between the arms ii of the thread guide carriers and the threads of the traverse bars.

Reference will now be made to the mechanism which actuato s the rock shaft 2 3, although for a complete description of this mechanism reference is made to my said application. Connected to one end of the rock shaft is a lever arm 2% which will hereinafter be sometimes referred to as the control lever. This control lever, as will presently be explained, is a spring activated lever. it bears a stud ii which, when the lever is turned down against the tension of its controlling spring with consequent anti-clockwise turning of the rock shaft 2Q, will become locked to a fork 2d. The control lever is unlocked from this fork at the end of the wind when the thread guide carrier strikes the stop ll. Thereupon the control lever, tensionally controlled as aforesaid, will rise with consequent turning of clockwise direction.

The tensional control of the control lever and its return from an unlocked position to a locked position with the fork, from which it has been previously released, is brought about by the'following described mechanism. Fixed to the end of the rock shaft it opposite that end to which thecontrol lever it is fixed is a lever arm til in direct opposing relation to the control lever arm 26, the two arms combining to form a complete control lever. At its end the arm it is connected through a folding joint ii to a two-armed lever s2 which lies in extension of the control lever to which it is attached and i pivotally mounted in the bed. of the machine. when the control lever 25 is released from its locked engagement with the fork is the lever will rise while the arm til of the complete control leverwill move downwardly. The inner arm of the lever 32 will consequently move downwardly and its oumr arm beyond the point of its pivotal attachment will move upwardly; On the return of the control lever to its initial locked position a reverse movement of these levers takes place. The line or levers are under the tensional control of a spring 35. One end of this spring is secured to the outer end of the lever 32. The opposite end of the spring is secured to a cam case 35. When the control lever 26 is in locked position with the fork 2d, the end of the lever 32 to which the spring 3 3 is attached will have heen moved down tensioning the spring. Upon the unlocking of thecontrol lever from the fork 28 the then tensioned spring 35, exerting force to' draw upwardly the end of the lever 32, will, through the line of levers, displace the arm 2% of the control lever upwardly from its locked connection with the fork and will rock the shaft it to which the control lever is secured in a clockwise direction. Thus it will be seen that the line or levers when locked is under the tensional control of the spring lit causing their displacement, as explained, when the arm 26, or control lever, is unlocked from the fork 2%. If new the end of the lever 32 be depressed a reverse action of the levers will take place and the control lever- 25 will again become locked to the fork 28 and the rock shaft 24 to which the lever is fixed will beturned in an anticlockwise direction;

Located above the end of the lever 32 within the case til is a clutch mechanism which is activated by the lever 32 when the arm 26 of the the shaft 2 3 in a control lever is released from it locked engagement with the fork 28, and which clutch mechanism is thrown out or disengaged when the arm 26 of the control lever is returned to its lockingv engagement with the fork 28. The clutch mechanism includes a continuously rotating worm wheel 38 which is driven by a worm 39 on a shaft 40 turned in any suitable manner in the operation of the machine. The worm wheel 38 is journalled to turn on the casing 35 and carries on its under side one or more pins 4|. Beneath the wheel 38 is located a freely rotatable cam disk 42 which bears a pin 43. This pin is adapted to have clutch engagement with one of the pins 4| on the continuously rotating wheel 38 when the cam disk is lifted, whereupon during the continuance of such engagement the cam disk 42 will be rotated by the wheel 38. The cam disk is lifted by the outer arm of the lever 32 as this arm turns upwardly on the release of the control lever arm 26 from its locking engagement with the fork 28. The outer arm of the lever 32 has secured to it a roller finger 45 which extends laterally beneath the cam disk 42 and acts to lift the disk as the arm becomes lifted. The cam disk 42 isheld against rotation by a stop 41 on the body of the frame of the machine which enters a slot 48 in the edge of the disk. When the stop is in this slot the cam disk cannot be turned. The cam disk can be turned when the lever arm has lifted it above'the plane of the stop 41 at which time the disk will be thrown into clutch. engagement with the rotating wheel 38 and be turned thereby. The action is one in which the cam disk 42 is made to have only a single complete revolution after the throwing in of the clutch, disengagement or throwing out of the clutch being effected at the completion of such revolution. To this end the cam disk is formed on the under side thereof with a projection or cam 50, which, when the cam disk is approaching the end of its single revolution will enter between the disk 42 and the finger 45 on the forward arm of the lever 32 and depress this arm, thereby turning the lever 32 and returning the arm 28 of the control lever again into locked engagement with the fork 28. The complete revolution of the cam disk 42 will now have brought the slot 48 in the edge of the disk into alignment with the stop 4'! on the frame, whereupon the cam disk 42 will be thrown out of clutch engagement witnthe wheel 38 by means of an arm 52. This arm is pivoted to the casing 35 and the end of the arm has drawing engagement with the top of the cam disk 42 by means of a spring 53, one end of which is connectedto the. end of the lever 52, and the other to the fore end of the lever 32.

While various operations in the complete operation of the machine are brought about, as re- .ferred to in my said application, through change in the location of the chain of levers just referred to following the unlocking of the control lever 26 from the fork 28 on the completion of the wind, including the disengagement-of the arms H of the thread guide carriers from the traverse bars, the stopping of the winding spindles and traverse bars, followed by the release of the wound bobbins, and the replenishment of the winding spindles with fresh bobbins to be wound; after which, upon restoration of the control lever to locked engagement with the fork, the operation of the winding spindles and that of the traverse bars will be restored, and, if no bunch is to be formed, the arms ll. of the threadguide-car riers will be moved down to have engagement with the threads on the traverse bars, yet, the part which is especially pertinent to the present case of bunch building centers around the operation of the rock shaft 24, and appurtenant thereto.

If no bunch building is desired on the bobbins, with no bunch builder attachment to the machine, then a progressive wind on' the bobbins will start'immediately when the arms ll of the thread guide carriers 8 are permitted to have engagement with the threads of the traverse bars through the lowering of the thread guide carrier release rods I2, the spindles and traverse bars having then been thrown into operation. When, however, a bunch is to be built upon the bobbins the lowering of the thread guide carrier release rods which throws the arms I l ofthe thread guide carriers into engagement with the threads of the traverse bars is suspended until the bunch has been formed, although the rock shaft 24 in the operation of the machine has been turned in an anti-clockwise direction to obtain such engagement. This suspension is brought about by locking the crank arm axle HI which extends into the gear case for a timed interval, or during the building of the bunch. The locking of this axle and the period during which it will remain locked is obtained by various parts of the builder mechanism located on or about the axle within the gear box I and to which detailed reference will later be made. The locking of the crank arm I9 is rendered possible by an establishment of lost motion between the arms 25 on the rock shaft 24 which connect with the crank arm 18 through the linkage 2 I, as previously described. This lost motion is brpught about by slots 25' in the linkage 2|, the pin connection between the arms 25 and the linkage rendering through the slots when the rock shaft is turned in an anti-clockwise direction. The

rock shaft 24 will then exert no force to turn the crank arms l8 and permits of the locking of the axle I9 and temporary fixing of all the crank arms.

During the period of suspension just referred to, inasmuch as the threads on the traverse bar cannot be relied upon to reciprocate the thread guide carriers during the building of the bunch,

, other means must be relied upon to obtain such reciprocation, and to this reference will first be made, reference being afterwards made to the manner in which the axle IE! is locked, the means for obtaining a timed interval'for its locking, and the subsequent release of this axle and consequent turning of the crank arms permitting of engagement between the arms ll of the thread guide carriers and the threads of the traverse bars as the progressive wind on the bobbins continues immediately upon the completion of the building of the bunch. First, however, with reference to the mechanism for reciprocating the thread guide carriers during the building of the bunch.

Arranged to turn in brackets 55 on the face of the gear box I is a rocker shaft 58 which is located above the thread guide carriers and between them and the face of the gear box. This rocker shaft carries rockers 51 which bear, respectively, against the backs of the thread guide carriers and move them along the traverse bars as the rocker shaft 56 is rocked. Reverse movement of the carriers, after being moved forward by the rockers, is obtained by the action of the then tensioned traverse springs I 4. Therocker shaft 56 is'rocked by means of a bent lever 58 the parts directly pivotally hung from off a shaft 60, the ends of which are supported within brackets BI fixed to the face of the gear box. This shaft is arranged above the rocker shaft 56 and between it and the gear box. The pivotal mounting of the lever 59 is such that it may be swung laterally into contact with the traverse bar, and it is normally urged in the direction of the traverse bar by a flat spring 62 connected to it and which bears against the shaft 60. Arranged upon the traverse bar is a collar 64. As will presently be explained, during the building of the bunch the lever 59 is maintained in a position just clear of the traverse bar, in the direction of which it is urged by the spring 62, where it may be struck by the collar 64 on the traverse bar as the traverse bar is reciprocated. and which will accordingly rock the lever 59. The rocking movement of the lever 59 is imparted to therocker shaft 56, for rocking it, through an arm 55 on the rocker shaft 56 which has a link connection 59 with the lever 59. The normal at rest position of the lever 59 is against a block Gll forming a stop on the rocker shaft 59, and the lever is held to yieldingly bear against this stop by a coil spring 56' on the shaft 56, one end of which is secured to the shaft and the other end to the adjacent bracket 55 within which the shaft is turning, the spring acting through the rocker shaft 55 and through the

arms

65 and 96, which form the link connection between the rocker shaft 56 and the lever 59, to normally hold the lever 59 in place. From its normal at rest position the lever 59 is displaced by. the collar 54 on the traverse bar. With the parts thus arranged and disposed, and working in co-operation with the traverse springs motion will be imparted by the traverse bars as they are reciprocated to reciprocate the thread guide carriers .for effecting a traversing lay of thread for forming the bunch on the spindles.

In this connection it is obvious that the length of thebunch may be made to depend upon the extentof movement of the rockers 51, and'this will depend upon the point, or points, where the link 66 makes connection with the arm 95, or with the lever 59, or with both of these elements, the extent of leverage for rocking the shaft 56 being thereby increased or diminished.

During the period that the lever 59 is beingmoved, when contacted by the collar on the traverse bar during the reciprocation thereof, the lever will bear not against the traverse bar, but will have sliding contact with a bar 58 on the linkage 2! which connects the crank arms Hi. When the control lever 26 is returned to its locked position with the fork 28, the rock shaft 24 will be turned in an anticlockwise direction with the effect of drawing the linkage 2i to the right, as viewed from the front of the machine. As the linkage draws to the right the bar 58 will be brought into a position where the lever 59, then released, will contact with the edgeof the bar and be maintained in a position just clear of the traverse bar and so that it may be struck by the collar on the traverse bar as this bar is reciprocated. The bar 68 accordingly functions both as a stop for the lever 59 and, also, as a slide on which the lever may move just clear of the traverse bar. The lever 59 is under the control of a withdrawal arm 10. This arm extends upwardly from the inner end of the rock shaft 24. Connected to the upper end of this withdrawal arm is a link H which is secured to an angle plate 12 fastened to the lever 59 below the point of its pivotal connection to the shaft 60. When the control lever is released from its locked connection with the fork 28 on the termination of the wind and the rock shaft 24 is thereby turned in a clockwise direction, the withdrawal arm 10 on the rock shaft will then be turned to draw the lever 59 into a disengaging position with relation to the collar on the traverse bar.

The lever 59 is also moved into a disengaging position with relation to the collar on the traverse bar during the period of the wind after the completion of the building of the bunch. This effect is obtained by a forward movement of the bar 68 against which the lever 59 is bearing during the building of the bunch. When the control lever is returned to its locked position with the fork 28, preliminary to starting a fresh wind, the rock shaft 29 will be turned in an anti-clockwise direction and consequently will tend to draw the linkage 2i to the right and will exert drawing effect thereon suflicient to move the bar 69 carried by it into a position where it will act as a stop for the lever 59 then released to bear'ag'ainst the stop, or in a position where it may be struck by the collar on the traverse bar as the bar is reciprocated. The normal action of the rocker shaft 29, preliminary to the beginning of a wind, if no bunch is to be built, is through the linkage 2l,to move the crank arms l8 sufliciently to allow the thread carrying arms of the thread guide carriers to have biting contact with the threads on the traverse bars. But as previously explained,

this action is suspended during the building of the bunch through the locking of'the shaft N to the axle of one of the crank arms. Accordingly, the crank arms, not being completely turnable until the bunch has been built, or not turnable to an extent sufficient to allow engagement between the thread carrying arms of the thread guide carriers and the thread on the traverse bar, are still turnable in an amount suificient to have moved the linkage 2!! to locate the bar 68 where it will act as a stop and slide for the lever 59 during the building of the bunch. When the bunch has been built, however, and the axle l9 released, which enables the crank arms E8 to complete their turning, thereupon the linkage 2! will have a further slight movement to the right, or one sufiicient for the bar 58 to move the lever 59 out of the contact range of the collar on the traverse bar marking the completion of the bunch building traverse, and at which same time the thread carrying arms of the thread guide carriers will have moved down, by the then permitted lowering of the rods 12, to have biting engagement with the, threads on the traverse bars which marks the beginning of the progressive wind which immediately follows the building of the bunch.

Reference will now be made to the manner in which the axle I9 is locked, to the manner of obtaining a timed interval for its locking, and to the subsequent release of this axle and consequent turning of the crank arms I8 permitting of.;;the fall of the rods lZE-and engagement between the arms H of the thread guide carriers and the threads of the traverse bars as the progressive wind on the bobbins continues immediately following the building of the bunch. Secured to the end of the axle I9 inside the gear. box is a looking arm 15. This locking arm is under the control of a spring 16, one end of which is secured to the arm and the other end to a fixture IT located within the gear box. lT'he spring is tensioned' and tends to draw thearm to the left, as viewed from the front of the machine. Located within the gear box is a bracket 19. Pivotally mounted upon this bracket is a combination keeper and lock release element 80 with which the locking arm 15 co-operates and which is provided with a downwardly extending wing extension 8|. The element 88 is under the tensional control of a spring 88. The turning of the axle I9 is controlled by this element 80 through the engagement of the locking arm 15 therewith. When the rock shaft 24 is turned in a clockwise direction following release of the control lever 26 at the termination of the wind, thereupon the locking arm 75 on the end of the axle ill will be turned in a clockwise direction withinthe housing formed by the element 88. When now the rock shaft 24 moves in an anti-clockwise direction following the restoration of the control lever 26 to its locked position with the fork 28, thereupon the locking arm 15 will be turned to the left, or in an anti-clockwise direction, until it engages a shoulder 83 on the inside face of the element 88, preventing further turning of the arm and consequently further turnin of the axle [9. All the axles of the crank arms I8, will then be locked to prevent their further turning, or such turning as will allow the drop of the rods l2 to permit of engagement between the thread carrying arms I I 'of the thread guide carriers and the threads of the traverse bars. Loosely arranged upon the axle l9 is a ratchet wheel 85 under the control of a return spring 86. Secured to project from the side of this ratchet wheel is a stud 81. The ratchet wheel is turned by means of a spring controller feed pawl 88 borne by a feed pawl arm 89 under the control of a reciprocating crank arm 90. This crank arm is vibrated in any suitable manner from off mechanism within the gear box which drives the spindles and traverse bars. As the feed pawl 88 is oscillated it turns the ratchet wheel 85 which is also under the control of a spring controlled ratchet release pawl 9|. When the feed pawl 88 has turned the ratchet wheel 85 in a determinate amount, or for a determinate interval of time, the stud 81 borne by the ratchet wheel will be brought into engagement with the bottom edge of the wing 8| to the element 80. Thereupon upon slight further turning of the ratchet wheel the element 88 will be lifted releasing thelocking arm 15 from engagement with its shoulder 83 and permitting further turning of this arm and the axle 19 in an anti-clockwise direction. This permits such further turning of the crank arms l8 as will drop the rods l2 to permit of engagement between the thread carrying arms H of the thread guide carriers and the threads of the traverse bars, marking the beginning of the progressive wind. The lifting of the element 88 tends also to release the feed pawl 88, and also the ratchet release pawl 9| from engagement with the ratchet wheel. The feed pawl 88 during its operation for turning the ratchet wheel has sliding contact by a tongue 92 on it with the edge of the element 80 so that when this element is lifted the tongue will move the pawl 88 out of operative contact with the ratchet wheel. The release pawl 9i is mounted on the element 80 and is provided with a similar tongue 93 so that lifting the element 80 releases this pawl from the ratchet wheel. With the pawls thus disconnected from the ratchet wheel it will be returned by its return spring 88 to the point of its starting. The time interval for forming the bunch depends upon the amount under the control of a setting wheel 94.

ing operation culminates when the element 88 is lifted, which releases'the feed pawl 88 from the ratchet wheel. The amount the ratchetswheel is turned depends upon its starting point and this is This setting wheel is loosely arranged on the axle l9 and bears on its side facing the ratchet wheel a stud 95. The ratchet wheel in turn, on its side facing the setting wheel, is provided with a stud 96 which, as the ratchet wheel is returned by its return spring 86, will engage the stud on the setting wheel, which determines the starting point of the ratchet wheel, this in turn depending upon the turned position of the setting wheel. The setting wheel is provided with a serrated edge 91 and is held in any determinate turned position by a pin 98 which fits in any one of the openings in its serrated edge for thus locating it in any determinate turned position, depending upon the desired location of the stud 95 carried by it. The pin 98 is borne by a stationary arm 99 fixed to extend from the bracket 19.
