'U'NETEQ STA GEORGE N. TAYL OR, OF EAST PROVIDENCE, RHODE ISLAND, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO THE NEW ENGLAND TRUST COMPANY, TRUSTEE, A COR-POBATION or MASSACHUSETTS.

Application filed. July 16,

T 0 all'whom it may concern.

Be it known that I, Gnoner. N. TAYLOR, of East Providence, in the county of Providence, State of Rhode Island, a citizen of the United States, have invented certain new and useful Improvements in Winding Machines, of which the following is a specification.

This invention relates to improvements in winding machines and particularly to winders of the friction or drum-driven type.

The essential purpose of the invention is to provide improved means for controlling the action of the copor cone-holder in its movement away from the friction-roll or driving-drum during the growth of the package being wound on said holder.

One object of the improvement is to provide positively acting means for causing the cone-holder to travel in a predetermined path whereby its base end will move away from the drive-roll at a fasterrate than that of its apex end, thus tending to cause the axis of the holder to assume a greater inclination to the periphery of the drive-roll whereby to increase the taper of the conical surface of the package being wound.

Another object or" the improvement is to provide means for controlling the position of the cone-holder longitudinally of the drive-roll during its receding movement therefrom, whereby to cause thelayers of winding on the cone to be disposed in proper relation to build the package with a convexed base and a concaved nose ,or apex end;

Another object; of the improvement is to provide means for resisting the movement of the cone-holder away from the drive-roll to effect an evenipressure of the surface of the cone thereagainst.

7 Another object of the improvement is toprovide a clogging-device for checking the return of the cone-holder toward the driveroll during the winding operation'whereby to eliminate the jumping or vibration of the cone caused by irregularities on its surface.

Further objects of the improvement are set forth in the following specification which describes preferred embodiment of the invention as illustrated in the accom panying drawings. In the drawings:

Referring to Figs. 1, Z-and 3 of the drawings, D designates the cylindrical driveroll or friction-drum from which the cop or package is rotated and usually the roll isit to lay the yarn inhelical coils on the package being wound. The driving connections for the drive-roll D and threadguide G are not herein shown and described in detailsince they may be of any usual arrangement as well known to those versed in the art. 7

It is the usual practice to wind the cone or. package on a relatively thin paper tube or shell C, shown in Fig. 1, and the means forfrotatively mountingthe. tube may consist of any suitable type of holder therefor. As here illustrated the cone-holder H comprises a mandrel 4 having conical endpieces 5 and Gadapted for insertion into the cone-tube C and provided with teeth, dogs or other suitable means, not herein shown, for securing the tube in place thereon. The mandrel 4: is rotatively mounted on a spindle. 7 which is held at one end in a support or hinge-member 8 pivoted in a slot at the end of an arm 9. The member 8 is pivoted on a stud 10to adapt it to be operated vmanually .to swing the mandrel 4: outwardly away from the drive-roll D to facilitate the placing of the cone-tube C thereon arm 9 carrying the mandrel 4 is fixedly supand the doffing of the package therefrom. At the outer end of the member-8 is a notch 11 adapted to be engaged by a detent or catch-12 on the end of spring 13' which is secured to the side of the arm 9 by means of screws 14 and nuts 15. The detent'l2 serves to hold the mandrel 4 in operative position with its axis in line with that of the drive-roll D, while permitting the swinging action of the mandrel in placing the cop tube thereon or removing it therefrom. The

ported at theouter end of a second arm'20 which controlsthe movement of the coneholder and the cop or package wound thereon. As shown in Fig.3, the arm 9 is mount. ed on a rod 21 and fixedly secured-thereto hy the screws 14 which fasten the spring l3- in place. The rod 21 is driven into a hub 22 at the end of the arm and projects substantially at right angles thereto.

Referring now to Figs. 1.and-2, the oppo site'end of the arm 20 is formed with-a sort of T-head compr sing two opposite exten- L sions23 and 24 carrylng rollers 25 and 26 which are pivoted on studs 27 driven into bosses at the extremities of the extensions, see also Fig. 3. The rollers 25 and 26 en-' gage curved groovesor guideways29' and 30 formed on the face'of'a vertical standard or plate 31 which is rigidly supported from a rod R forming a part of the frameworkof the winding mach ne, see Fig. The arm 20 is held in position with its rollers 25 and 26;

7 engaging the grooves 29 and 30 by means of a front cover-plate 32 fastened to bosses 33 on the standard 31 by screws 34, see Fig. 3. On the rearward sideof the arm 20 is afinished face35 which slides against the face of a machined rib. 36 projecting forwardly from the standard31. F astened to'the front of the arm 20 by means of a screw 37 isa flat spring 38 having a convexly formed button 40at'its outer end which is adapted to bear against the rearward face ofthe cover-plate 32. The tension of the spring 38 maintains the arm '20 bearing against the rib 'or track 36on the standard 31 while pro,- viding a slight friction to resist the upward movement of the arm as its rollers25 and 26 travel in the curved grooves or guideways 29 and 30; It will be noted by reference to Figs. 1 and 2 that the slots or guideways 29 and 30 are curved in opposite directions and areoffset, one inrelation to the other. This providesthat as the rollers25 and 26 travel in their respective slots the latter will act as cams to tilt or rock the arm-2O during its upward movement, 'whereby to shift the cone-holder H bodily in angular relation to the drive-roll D in the manner and for the purposeas hereinaftermore fully explained.

-As I the cone-holder H swings upwardly from the drive-roll Djits'retrograde. movement is checked by a dogging-device which is constructed and arranged as next de scribed. Surrounding the rod 21 which sup- .ports the cone-holder arm 9 is a hub 42 which is securedfixedly in place; by a setscrew-43, see Figs. 3 and 4. Onthe-side of the hub 42 is an arcuate quad-rant 44 con-' str'u'eted integral therewith and formed with ratchet-teeth 45 on its concaved face.

Adapted to engage with the teeth 45 on the quadrant 44 is a hooked pawl 46'which is pivotally DIOUIltGClgOIl an arm 47 projecting from a hub 48. As shown in Fig.5, the hub 48is provided with an axial stud 49 journaled in a bearing 50 projectingffrom the side of an upr'ight plate or standard 51v which forms apart of the machine frame, see Figs. 1 and 2. Referring againto Figs. 4 and 5, the arm 47 is of bifurcated construction to adapt the'quadrant 44 to pass between its opposite sides. The pawl 46 has a hub 52 pivoted between the sides of the arm 47 by means of a pin 53 driven through the arm and engaging a vertical slot 54 at the lower end of the pawl, see Fig. 4. The slot 54 permits the pawl 46 to rock on its pivot and also to-move up and down'to a limited extent in the manner and for the purpose as hereinafter more fully explained.

The pawl 46 is normally maintained in its raised position by means of a flat spring 55 which bears against a rounded toe'56 at its lower end. The spring 55 is fastened to the 7 under side of the hub of the arm 47 by'a screw 57, see Fig. 4. Projecting from the side of the pawl 46 is'a pin 58 adapted to" ice strike against a finger or stop 59 on the side of the arm 47 to limit the rocking move ment f the pawl. The hub 48 of the arm 47 is extended outwardly as shown in Fig. 5 and bored to receive a rod 60" arranged coaxially with the bearing-stud 49 at its opposite end. The rod 60 is fastened in the bore'of the hub 48 by means of a set-screw 61. 'The rod '60 is bent at an angle at its outer end to adapt it to serve as a handle'62 for rocking the arm 47,to release'thepawl. '46 from theteethonthe quadrant 44. The

rod 60 may also be connected to operate the starting and stopping mechanism ofthe' ma chine, but as these connections are not essential tothe present invention they are not herein shown or described. 'Su'flice it to state that the rod 60 is rocked in'the direction 5, the bearing iii) ' against the tension of the spring by a detent-mechanism arranged as next described. Referring to F ig. 5, the rod 60 which projects from the hub 4L8 of the arm 4:7 carries a detentlever 67 fastened thereto by a setscrew 68 in its hub. The lever 67 extends downwardly and outwardly, see also Fig. 4, to adapt its lower squared end to engage witha shoulder or notch .69 in the side of a detent-member or latch-plate 70. The

. latch-plate 70 may be operated by suitable instrumentalities, not herein shown, to release the lever 67. to allow the rod 60 to be rocked from the spring 65 to cause the automatic stopping-of the machine in the manner as usually arranged in apparatus of the present type. i a a The structure and arrangement of the essential elements ofmy improved mechanism having now. been described. in detail its method or". operation will nextbe' explained: To prepare the machine for operation the mandrel 4 is swung outwardly on its pivot 10: and the cop-tube C applied thereto; after which the mandrel isswungback to the position illustrated in Fig. 3, where it is held in operative relation by the detent 12 engaging the notch 11 in. the hinge-member S. The thread or yarn 3 represented by dash-lines in Fig. 3, is'drawn up from its source of supply, not herein illustrated, threaded through the groove in the threadguide G, and its end secured to the tube 0 by giving it a few turns therearound. To start the machine the controlling-handle 62 is rockedin.thedirection indicated by the arrow or in Fig. 2 against the tension of thespring 65. This action causes the winding operation to be started by moving the cop-holder H down against the drive-roll I D. and to maintain the machineroperative the latch-memberTO engages automatically with the end of the detent-leverfi'? in' the manner illustrated in. Fig. 5. In turning thehandle 62 to start the operation of the machine the arm 47 is rocked in the same direction and to a suflieient extent to cause it to release thepawl iti from the quadrant 44. This action is effected by the engagement of thefinger .orstop 59 on the arm ,47.

withthe pin 58 on the side of the pawl, see

Fig. 4:. Upon the release of the pawl 46 from the quadrant M the weight of the copholder. H will cause the latter to drop to bring the cop-tube G into contact with the periphery. ofthedrive-roll D. As the coptube C is thus brought down against the drive-rollD the frictional contact between their peripheral surfaces will cause the tube and its mandrel i to be .rotated to wind on the yarn yfas it feeds. through the threadguide Meanwhile, the threadguide G is reciprocated back and forth along the tube 0 to traverse the yarn y longitudinally thereof, whereby it is deposited on the tube in helical coils to build up a cross-wound package in the manner -as well known to those versed in the art. As the yarn is built up on the tube C it will cause the mandrel a to rise away from the drive-roll D and the lifting action of the mandrel is controlled by the action of the movable arm 20 connected to its end. In winding packages of the present type, that is conical cops it has been found expedient-to start the winding with a predetermined taper and to gradually increase the taper or pitch of the cone as the latter grows in diameter. Usually the conical core or cop-tube C on which the package is wound has a predetermined taper which is ofthe-maximum pitch on'which it is practical to hold the first coils of winding without slippage. As the package increases in diameter, however, the windings have a better foundation so that the layers may be inclined at a greater angle to the axis of the cone without danger of slippage. It is desirable to have the outer layers of the cone inclined to a greater extent than the inner ones in order to insure freedom of delivery of the yarn in unwinding the cone, and hence it has become the preferred practice to start the winding withthe minimum taper and to gradually increase the inclination or taper on the surface of the cone as the latter in creases in diameter. To provide for this increase in the taper of the cone during its building various methods of laying the yarn thereon have been employed. One preferred system for building up the yarn faster at the base of the cone than at its apex end to increase its taper is to cause the threadguide to lay the coils or turns of the yarn in closer relation toward the larger end of the cop-tube. That is to say, the threadguide G is given a variable motion in its traverse along the cone-holderH, its speed of reciprocation being accelerated toward the apex end of the cone and decelerated in the opposite direction. The means for effecting this peculiar action of the threadguide are not herein shown or described since'they are disclosed in my U. S. Patent No. 1327.035, granted August 22, 1922s Suflice it to state that in the present machine the cone or package X, representedby dot-and-dash lines in Fig. 2, is built up.

faster at its-base than at its apex end and consequently the cone-holder or mandrel 4 must be gradually tilted to bring its axis p the outcr'end of the arm isforced up wardly under 'the rising action of the coneholder H the upper roller will travel in a curved path defined by the groove 29 which has a general inclination to the right; While the lower roller EZG traVeling in the groove 30 follows a, curved path inclined in the oppositediiection, ort'o the left. The curveand inclination of these grooves are plotted to give a certain definite path of movement to the. mandrel 4 as next explained. In ageneral sense the point of connection offthe mandrel 4: with the arm 20, represented at min-Fig. 1 and at 6 in Fig. 2,'swings in a path defined by 'the broken line a in Fig. 2. This path is not a true are but follows a reverse curve generated by the point-a; swung from a pivot located to the right awlistance approximately four or five times the length of the package; with proper tilting actionof said pivot moving constantly to the left in a "horizontal plane. The purpose of this peculiar action of the arm 20 to move its pointof connection with the cone-holder H in the path as indicated is to effectthe the mandrel l while controlling its position longitudinally of inscribed from a center defined by the interstantially flat;

the drweroH =D. It is obvious that lithe cone-holderwere sw'ungiipwardly onan arc section of its axis with the face. of. the driveroll-Dthen its rising movementhrould cause the mandrel l to be shifted to the right to a'conside'rable extent in relation to the -posi tion of the drive-roll D and the path of traverse 'of the thread guide'G. Such a direction of movement'of the mandrel would result in building the base and apex ends of the cone substantially perpendicular to the surface of the tube G or, mother words the ends of the-cone would be formed sub- In order to provide 'for greater stability of the winding and also to prevent overruns or Cobwebs on the base of the cone *it is of advantage to form the base slightly converted. It will be observed from F ig.'2 of the drawings that as the cone-holder H travels in the plot-ted path a5?) the mandrel '4 will be maintained in a. predetermined position in longitudinal relation'to the drive roll D whereby to cause the cone to be "built with the proper-degree o'fficonvexity 'on its base. Stated *briefly, the'movement of the cop holder H awa from the drive-roll D is controlled by the arm 20 and its correlated mechanism to al: low the mandrel 4; to tilt in proportion to the increase in taper on the surface of the cone being wound without causing the cone to be displaced in such manner as to tend to build its base to-o flat. Furthermore, the positive connection of the cone-holder H with the arm 20 insures that the cone shall be maintained constantly in position with V yarn is wound on to the cone.

its axis inia' vertical plane coincident with the axis of'the drive-roll D whereby toprevent it from assuming a skewed relation thereto. This latter provision is important as insuringa 'full contactjof the'cone with the dri'veu'hll along its whole length. It

will thus be se'en'that the relation of "the cop-holder H to the drive roh D is con trolled positively and definitely throughout the whole windingoperation and in this the shape of the'cone is regulated within predetermined limits "whereby to secure amoreuniform-product of superior quality.

This improved means for positively and" automaticall controlling the movement of the cup or cone-holcler'during the building of the package is believed to be broadly 7 novel in theart.

As a further means for controlling the action of the cone-holder H to check its re-' trogressive movement toward thedrive-roll D Ihave provided the improvedadoggin device,which functions as follows: In starting the machine tooperate, in the manner as before exl'o'lainetltherockingof the handle 62 tilt-s the arm 47 into'pos'ition to allow the pawl 46 to engage with the teeth 45 bathe,

the drive-roll with a'j'umping or vibrating action WhIC-h prevents a uniform driving contact and thus causes imperfect winding.

For instance-if the con were liftedto such an extent that the pawl 46 skippeda tooth on the quadrant 44 the eop-holde'rmight be held with the surface of the cone out of con tact with the drive-roll except at the high point on the cone and consequently the driv ing action of theroil would becomeiirregula'r. Such abnormal functioning oft-he apparatus tends to'cause'faultsin the winding the lower toe H. It frequently happens' I p regularities tend toqlift the cone 0E from which are aptto be exaggerated as morc To guard against such conditions I have'pi'ovided for an inductive release of the checking-aetion of the pawl 46 as next explained. As before described, the pawl 46 is pivoted'to the arm 47 in such manner as t opermit it to resend fall slightly under the control of the spring 55. herefore, when the cone jumps away from the drive-roll to such an extentthat the pawl 46 skips a tooth on thequadrant Mcyim'mediately this jumpingaotion is overcome the weight of the cone-holder acts to force'the pawl 46 downward against the pressure of its spring 55. This relief-action of the pawl is provided for by its'slot' 54 which allows it to slide up and down on the pivot pin 53; but as soon as the cone begins to rise again under its normal-growth in diameter the vertical play of the pawl will be taken up by the spring 55 to force the pawl back to its normal position, as illustrated in Fig, 4. It will thus be seen that through this, automatic relief-action of the pawl 46 the cone-holder His controlled in its movement to insure a smoother, more uniform driving action of the drive-roll D and consequently the winding operation is rendered more uniform and the character of the product materially improved.

The operation of the'machine is arrested automatically, upon the breakage of the yarn or the completion of the package, through the employment of stopping-means of any suitable arrangement. This part of the apparatus forms no part of the present invention, however, and is thereforenot herein shown or described; but it is to be noted that when thedetent-l'ever 67 is re leased from the notched latch-plate 7 0 the spring will actto rock the arm 47 to raise the pawl 46 bodily and the engagement of the pawl with the quadrant 44 will cause the latter to be forced upwardly to lift the package away from the drive-roll D to arrest its rotation.

Various modifications may be made in the structure and arrangement of the parts of my improved apparatus without departing from the spirit or scope of the invention; therefore, without limiting myselfto the exact embodiment herein shown and described, I claim: r
