.1 bins of generally cylindrical form wound with conical chases and tapered or pointed at the nose or delivering en A particular object of the invention is to [provide a winding machine in which the thread-guide is maintained in close proximity with the tapered chase on which the wind-- ing is being performed while bein held away or out of. contact with the sur ace of the winding so as'to avoid any chafing action on 3 the yarn or other material.

Another object of the invention is to provide a winding machine having a reciprocating thread-guide for winding the yarn witha predetermined length of traverse'in conical or ta cred chases and adapted to advance longitudinally with respect to the winding-spindle as the layers of winding are deposited in place, with the delivering part of the guide traversing in a path inclined to the axis of the winding-s indle and controlled in its traverse to hol it away from the surface of the winding.

Another object of the invention is to provide a winding machine of the type specified 35 having means for adjusting the controlling means for the thread-guide in accordance with the taper of the surface on which the winding is being performed as regulated by the size and shape'of thebobbin.

Another object of the-invention is to provide a winding machine of the type specified in which the thread-guide controlling means is operated directly from the traversing means to eflect a control of the guide 'in synchrony with its traversing motion.

Another object of the invention is to pro-' vide controlling means for the thread-guide of the winding machine which is simplein construct1on,. efiicient in action and proof against wear on or derangement of the mechanism.

Further objects of the improvement are set forth in the following specification which describes a preferred form of construction of the invention, by way of example only, as illustrated by the accompanying drawings. In the drawings:

In the resent drawings the invention is illustrated as ap lied to' use on a winding machine of well own type comprising the essential elements of a rotating windingspindle, a traversing thread-guide, a traverse-frame for supporting the thread-guide l to adapt it to be reciprocated longitudinally of the winding-spindle, anda rotar cam for reciprocating the -thread-gui e. In

Figs. 1 and '2 of the drawings, 2 designates the box-like. frame on which the-various ele mentsof the winding mechanism are mounted and 3 is the rotatable winding-spindle lan view of the detent-arm and journalled in suitable bearings 4 at the top of the frame. Journalled in bearin s 5 on the sides of the frame 2 is a cam-sha t 6 exdriven from a countershaft or motor and the.

cam-shaft connected rotatively therewith through the means of belts, gears or other instrumentalities providing for the proper ratio of speed between the two shafts.

The winding-s indle 3 overhangs its bearings at one end 0 the frame 2 and is provided with a suitable holder or mandrel for supporting the bobbin-receiver or tube C on which the winding is performed. As herein shown the winding-spindle 3 carries an enlarged conical boss or support 8 for receiving the tapered or conical butt end 0 of the paer bobbin-receiver or tube 0, and projectmg forwardly therefrom is an enlarged cylindrical mandrel 9 which receives the tubular portion a of the bobbin tube or receiver C. Suitable means, not herein shown, are provided for securing the bobbin tube or reoeiver in place on the mandrel of the winding-spindle to hold it rotatively therewith.

The traverse-frame 10 which supports the thread-guide to reciprocate longitudinally of the winding-spindle 3 is constructed with a horizontal cross-member 11 having opposite depending arms 12 and 13 formed with hubs 14 and 15. The hubs 14 and 15 are mounted to hinge on bushings 16 fixedly held in the bearings 5 on the frame 2 in which the camshaft 6-is journalled to rotate. A longitudinally-extending groove 17 in the cross-member 11 of the traverse-frame 10 provides a horizontal trackway for a slidable rod 18. One end of the rod 18 is connected to a crosshead or slide19 which carries a stud or roller 20 engaging in the helical groove 21 of the cam 7. It will be understood that the cam 7 is secured fast on the cam-shaft 6 and the rotation of the latter turns the cam to reciprocate the slide 19 and rod 18. The opposite or forward end of the rod 18 carries an upright arm 23 connected .to a parallel sliding int rod 24 which constitutes the traverse-bar for reci rocating the thread-guide 25. As shown lie present drawings, the traverse-bar 24 is mounted to slide in bearings 26 and 27 on a supplemental frame 28 attached to an over hanging portion 29 of the main traverseframe 10. Referring particularly to Figs. 2 and 3, the supplemental frame 28 is constructed with a rail or bar 30 clamped to an upstanding flange 31 on the overhanging portion 29 of the traverse-frame 10 by means of screws 32. The lower edge of the'rail 30 overhangs the groove 17 in the cross-bar 11 of the traverse-frame 10 and is formed with an arcuate bearing face abutting the side of the rod 18 to hold the latter in place in the groove, see Fig. 3.

The traverse-frame 10, as before stated, is swiveled to swing on the axis of the camshaft 6, being mounted to adapt it for adjustment to set the traverse-bar 24 in proper relation with respect to the axis of the windingspindle 3, this adjustment being altered for winding bobbins of different diameter as hereinafter more fully explained. The traverse-frame 10 is normally held in fixed position by means of a detent lock shown in detail in Fig.3 Referring to Fig. 2, a horizontal rod 33 extends through the side of the forward arm 12 of the traverse-frame 10 and is supported in a lug 34 at the end of the traverse-frame extension 29 and also in a lug 35 at the outer end of the supplementary frame 28. The rod 33 is rotatable in its bear-- ings and carries a weighted d etent-arm 36 secured in place thereon by means of a setscrew 37 The detent-arm 36 is formed on one side with a detent lug or latch 38 which is en* gageable with a shoulder 39 on a fixed locking-member 40, see Fig. 3. The locking-member 40 is of arcua e form and provided with a slot 41 for receiving a bolt 42 by means of which the lock is fixedly clamped to the N side of the frame 2. The locking-member 40 may be adjusted in position by loosening its bolt 42 so as to set the detent-shoulder 39 to hold the traverse-frame in fixed position with the traverse-bar 24 in. proper relation to the winding-spindle 3. The lug or latch swing away from the winding-spindle so that the bobbin may be more readily dofi'ed therefrom. As herein shown the rod 33 carries an upright lever 43, see Fig. 2, which has an inclined upper end 44 adapted to be engaged by the thread-guide 25 to rock the rod to release the detents. The lever 43 may be adjusted longitudinally of the rod 33 to cause it to be engaged by the thread-guide 25 when the latter has been moved outwardly on the traverse-bar 24 to a predetermined extent in winding a bobbin of the required length. v

As before stated, the traverse-bar 24- is mounted to slide in the frame 28 and, as shown in Fig. 2, the rod passes through bushings 47 driven into the bearings 26 and 27 on the frame. At the outer end of the frame 28 the bearing 26 is extended to provide a guard for the end of the bar as it slides to its extreme of traverse. Referring to Fig. 3, the arm 23 which connects the traverse-bar 24 with the lower rod 18 has an oflset portion 48 fixedly held in a slot in the rod. At its upper end the arm 23 is bent around to encompass the traverse-bar 24 and is clamped thereto by means of a screw 49. Referring to Fig. 4, the traverse-bar 24 is of usual construction having screw threads 50 cut into its side in eccentric relation to its axis. The screw threads 50 are adapted to enga ecorrespond ing threads on the interior a cylindrical nut or sleeve 51 which is rotated to advance the thread-guide longitudinally of the traverse-bar 24. The sleeve or nut 51 extends between and is straddled by the legs 52 and 53 of a bifurcated thread-guide holder 55, the ends of the legs being provided with bearings 56 and 57 swiveled onthe bar 24 to adapt the holder to oscillate about its axis. The threadide proper may be constituted by a groove porcelain roll 58 secured to the outer end of the holder by means of a screw or stud 59.

Fixedly secured on thesleeve or nut 51 is a flanged disk 60, to the side of which is attached a contact-wheel 61. The contactwheel 6.1 has a flanged peripheral rim adapted to make contact with the surface of the winding on the bobbin whereby to turn the nut 51 on the bar 24. The periphery of thecontact-wheel 61 makes contact with the base of the conical chase of the winding at each rearward stroke of the thread-guide 25 and is thereby rotated to aslight extent to turn the nut 51'to feed the guide progressively outward along the traverse-bar 24. The threaded bore of the nut 51 is of larger diameter than the bar 24 so that it may be moved laterally to disengage its threads from the, threads against the rim of the disk on the nut 51:"

The construction and arrangement ofthese parts is substantially the same as usually employed on bobbin and cop winding machines in which the thread-guide is advanced longitudinally of the winding-spindle to deposit the yarn in forwardly-stepped courses laid on an inclined or conical chase.

As the thread-guide 25 is reciprocated longitudinally of the winding-spindle 3 the thread-guide holder or arm 55 oscillates about the axis of the traverse-bar 24 to adapt the feeding part of the guide to follow up and down the inclined chase of the bobbin being wound. In previously used bobbin winding machines of this type the thread-guide is arranged to. bear against the surface of the winding to direct its course up and down the inclined chase. It has been found, however,

that when certain materials such as silk, rayon and other delicate filaments are being wound the contact of the guide with the surface of the winding causes a chafing and 1 struction of the invention the means for controlling the actionof the guide for this purpose consists of positively driven mechanism "for oscillating the thread-guide holder 55. on

the traversebar24 during the reciprocatory motion of the guide. The guide-controlling means is operated synchronously with the guide-traversing means and apreferred form of construction of the mechanism will next be described.

Referring to Figs. 1, 2 and 3, the threadguide controlling means comprise a rockable guiding-track 65, preferably constructed in the form of a sheet-metal yoke or bifurcated frameas illustrated in perspective view in Fig. 5. The frame 65 is constituted by a longitudinal rail or track 66, preferably of angle-iron shape in cross section with laterally-extending arms 67 at its ends. The arms 67 are provided with holes 68 whereby the frame 65 may be rockably mounted on the bushings 47 which project from the bearings 26 and 27 on the supplemental traverse-frame 28. As shown most clearly in Figs. 3 and 4, the leg 53 of the bifurcated thread-guide holder 55 is provided with an extension or arm 69-which is folded over at its end to provide a double-sided shoe or slide 70 adapted to straddle the upper side of the .angularly shaped track 66. Through this means. the

thread-guide 25 is connected to be moved by and with the oscillatable frame65 during the reciprocation of the guide and as it feeds outward along the traverse-bar 24 with the shoe 70 sliding on the track 66.

As one means for actuating the controlling means in synchrony with the traversing movement of thethread-guide, Figs. 1 and 3 illustrate the frame 65 connected'to be oscillated from a crank or eccentric rota-ted from form of construction the cam-shaft 6 carries a wheel 71 fixedly attached to its end by means of the stud or screw 72, see Fig. 2, and

pin 75. The disk 74 ispreferably adjustable in eccentric relation with respect to the axis of the cam-shaft 6 to vary the throw of" the crank-pin 75 whereby to alter its ran e of action. For this purpose the disk 4 is formed with a radial slot 76 for receivin the screw 77 which clam s it to theface 0 the boss 73 on the wheel 1.

The crank or eccentric 74 is connected to oscillate the frame by means of a link or connecting-rod 78. As herein shown the link 78 comprises two sections 79 and 80 which are slidable on each other to adjust the length of the connection in accordance with the adjustment of the crankin and also to properly set the thread-gui e in spaced relation with respect to the surface of the winding on different types and sizes of bobbins. One section 79 of the link 78 has its end bent around in a loop 81 engaging around the crank-pin 75, and the other section has a similar loop 82 connected by a pin 83 to a bifurcated member or yoke 84 which is fixedly attached to the back of the track 66. The two sections 79 and 80 are held together b strap-like clamps 85 enclosing thelr over apped portions, the clamps being provided with thumb-screws 86 adapted to bind against the parts to lock them in adjusted relation. By releasing the screws 86 the two sections 79 and 80 of the connect ing-rod 78 may be slid one on the -'other to shorten or extend its length.

Themethod of operation of the machine in winding a bobbin is as follows: The paper tube or other bobbin-receiver C is placed on the mandrel 9 of the winding-spindle 3 and the end of the yarn or other strand material leading from its source of supply, not herein shown, is attached to the tube in any suitable manner. The strand y may lead from below or, as shown in the present drawings, it may draw downwardly from a supply placed above the machine, being carried around the porcelain roll 58 to feed therefrom to the surface on which the winding is performed.

Prior to the commencement of the winding operation the traverse-frame 10 is set in the position illustrated in Figs. 1 and 3 with the detent-lug 38 on the latch 36 engaged with the shoulder 39 on the locking-member 40 to hold the frame in fixed relation. The threadguide 25 is initially carried back toward the rearward end of the traverse-bar 24 to start the winding at the base of the bobbin, the settin of the guide being accomplished by releaslng the nut 51 from the threads on the bar in the manner as previously explained;

The thread-guide 25 is thus adjusted to starting position with its contact-wheel 61 at a oint opposite the large end ofthe conical utt 0 of the bobbin-receiver C to adapt it to contact with the yarn as it winds thereon, see Fig. 3. The eccentric plate or disk 74 is adjusted to regulate the throw of its crankpin 75 to impart an oscillating motion to the frame 65 sufficient to rock the threadguide 25 between the positions illustrated in full and dash lines in Fig. 3.

The link or'connecting-rod 78 is adjusted to regulate the position of the frame 65 so that when it is rocked downwardly to the full extent as shown by the full lines in F ig.3 the roll 58 of the thread-guide 25 will just clear the rim of the butt of the carrier C. In other words, the adjustment of the eccentric 74' and the connecting-rod 78 is such as to provide for the proper extent of oscillation of the thread-guide 25 and to also control its operative relation with respect to the surfaceon which the'winding is performed to insure that as it travels up and down the incline'it will be prevented from contacting with the connected therewith by means of the arm 23.

The reciprocation of the traverse-bar 24 traverses the thread-guide 25 back and forth longitudinally of thewinding-spindle 3 with its extent of traverse regulated by the throw of the cam 7 which is proportioned to the length of chase to bewound. At the start of the winding the thread-guide 25 will be traversed between the base end of the conical butt 0 of the carrier C and the apex end thereof to deposit the strand material in helical coils thereon. As the guide'travels forward from the base end of the butt 0' the turning of the cam-shaft 6 rotates the eccentric 74 to rock the frame 65 upwardly to the position indicated by the dash lines in Fig. 3. This rocking action of the frame 65 causes a corresponding oscillation of the thread-guide arm 55 to carry the porcelain roll 58 inwardly towards the axis of the bobbin, and in this way the delivering portion of the guide is caused to travel down the incline, or in other words to follow the conical chase so that it is maintained close to the surface on which the wind ing is being formed to properly direct the strand thereto. As the thread-guide reaches the forward end of its traverse thecrankpin 75 on the disk 74 crosses dead center, whereupon it will impart areverse motion to the frame 65 to rock the thread-guide roll 58 outwardly or back to the osition indicated by thefull lines in Fig. 3. n this manner the oscillatin movement of the thread-guide is synchronized with its longitudinal traversing motion so that the'roll 58 will invariably follow the inclined surface of the windingwithout bearing thereagainst.

As the strand material is deposited on the 'conical butt 0' of the receiver C it will {be built up in a layer of crossing turns or coils and eventually, at the'rearward stroke of'the thread-guide 25, the contact-wheel 61 will be engaged by the winding as indicated in Figs. 1 and 3. During this brief engagement the contact-wheel 61 is rotated to a slight 5 extent to feed the nut 51 along the traversebar 24 to advance the thread-guide towards the tip end of the bobbin. In this way the.

bobbin is built u in a series of overlying courses of coils w ichadvance rogressively along the axis of the receiver to form the bobbin witha cylindrical body and tapered or conical nose-end as indicated by the dotand-dash lines in Fig. 2. As the threadguide 25 feeds outwardly along the traverse- 5 ar 24 the shoe 70 on the guide-holder 55 slides along the track 66 to maintain the connection between these parts. After the thread-guide 25 has been fed along the traverse-bar 24 to an extent sufiicient to complete the bobbin to the required length, finally, at the outward traverse of the guide, the leg 52 of its holder 55 will make contact with the inclined end of the arm or lever 43 to rock the rod 33. The rocking of the rod 33 releases the detent-latch 36 from the lockingmember 40, whereby the traverse-frame 10 1s caused to swing back to remove the contactwheel 61 from contact with the winding, At this juncture suitable instrumentalities, not herein illustrated, are brought into action to disconnect the drive of the machine to arrest the winding operation so that the completed bobbin may be dofied from the winding-spindle 3 and a new tube or receiver placed 5 thereon.

It will be observed that the present imgrovement provides a simple yet highly efcient means for controlling the operation of the thread-guide to maintain it in close proxm imity to the tapered chase on which the winding is being performed, while preventing it from hearing against the surface of the winding to chafe or abrade the strand material.

The controlling mechanism for the guide ma be adjusted in accordance with the shape an dimensions of the bobbin being wound without disturbing the synchrony of o eration between the traversing motion 0 the ide and its oscillating action.
