9 Claims.

The invention-relates to a machine for winding onto a beam, or drum, yarns, or threads, drawn off a plurality of separate spools; or cops.

Among the objects ofthe invention are th'e fol'- lowing:

To provide a machine in which the spools oi which the yarn is drawn may be of any desired size, or even diierent in size. The present tend'- ency is to increase the size of the spools in orderl 1 0 to save kn tying, and form larger wound masses. To provide a machine which can be loperated at high speed,v

To provide a machine in which the spools from which the yarn is drawn may have diierent relative amounts vof yar'n thereon, whether the lspool befull or not to be immaterial in the operationof the machine. To provide a machine in whichthe spools from whichtheyarn is drawn shall be rotated bypull B0 or draw ofthe yarn, be subject to n'o braking eiiect during the draw of the yar'n, and shall only e offer such resistance to rotation as attends cer' tain work performed by the rotating spools that will cause all to be rotated at the same peripheral 25 speed, and cause those rolls having more yarn thereon, and which are rotated more easily by draw ofthe yarn, to assist in facilitating the ro` tation 4of other of said spools having less yarn and 'which are rotated less easily by draw of the 3 yarn, with the effect that the yarn may be drawn from allv the .-spools with substantially uniform andcpmparatively light tension upon the yarn,

so insuring against breakage. 35 To provide a machine in which the yarn shall be drawn from the separate spools with a direct andpositive feed independent of the drum, or beam, onto which the-yarn .is ultimately wound. To provide a machine in which the rotation of o the spools from which the yarn is'drawn shall be matically inkorder to prevent continued rotation of the spools by reason of their momentum which would cause disarrangement .and tangl'ing of the To provide a machine in which theyarn may be uniformly wound upon the drum, or beam, ontol which it is ultimately wou'nd, at a determinate l)tension irrespective of the speed ofthe machine, d50 or the amount of yarn on the drum.

The invention can best beseen vand understood by reference to the drawings in which Fig. 1 is a side elevation of the machine. Fig. 2 is a plan of some of the parts shown in 55 Fis. 1- Y stopped when the yarn feed stops, and. this auto?` (Cl. 24a- 45) Fig. 3 is a front'elevation ofthe winding drum forming a part of the machine.

Fig. 4 is a cross sectionof various parts pertaining to the drive of the winding drum.

Referring to. the drawings: I represents the 5 spools off which the yarn is drawn to be wound uponadrum'Z.l

The spools I are-mounted upon a creel 3 having upright side frames 4, l, withinv and between which the shafts Ii of lthe spools are mounted to l0 turn.

Mounted to have traction bearing against the yarn on each of the spools 3y is a set of rollers 1.

These rollers are preferably made of rubber in order to have good frictional contact with the ,u

yarn. They are, also, preferably pneumatic rollers in thev nature of small pneumatic tires; Each set of rollers is mounted to turn lupon a shaft 8. 'I'he shaft bearing each set of rollers lies parallel to the axis of the spool which the rollers are engaging, and is iixedly borne by side bars 9, 9, on which are hung pendant weights III. Eachset of side bars 9, 9, is pivotally arranged to turn upon a shaft I2. All the shafts I2, lie parallel with the shafts 8. They are arranged to turn on the side V frames I, l of the-creel 3 between which the shafts are interposed and the ends of the shafts I2 are preferably mountedto turn in ball bearings, I3 on the side frames in order that the shafts may turn freely. Lateral displacement of the rollers I -on the vshafts 8 on which they are mounted to Fixed to the side o f each of the rollers to turn therewith, and with axis the same as that of theroller, is a grooved wheel or pulley I6.' These pul- `leys carried by the respective rollers are connected by belts I1 to pulleys I8 keyedto the ro4 tary shafts I2. Borne also by the rotary shafts 40 I2 keyed thereto are sets of pulleys I9, I9. Adjacent sets of these pulleys I9, I9 are connected to. rotate in unison bybelted connections 2li.

As willI later be explained yarn deposited upon the drum 2 is drawn from oil! the spools I, and the 45 spools I are rotated by pull of the yarn as the yarn is drawn off these spools. The amount of yarn on the spools may vary. Some of the spools may be full of yarn and others of the spools have much less, or even little, yarn thereon. Those spools having the more yarnthereon will be turned more freely by pull of the yarn than will thev `spools bearing a lesser amount of yarn. It is necessary that the spools all turn with the same `peripheral speed in order that the yarn may un -55 and held to have a determinate friction contact with the yarn on the roll by the weighted pivoted frames which bear these rollers. With the rollers thus engaging the yarn the rollerswill be turned as the spools are rotated by'unwinding of yarn from them.V By reason of their belted connections all the rollers will turn in unison and with the same peripheral speed. Accordingly, all the spools will be governed to turn with the same peripheral speed so that the windo speed of the yarn will be uniform for all the spools. Inasmuch vas all the rollers are interconnected and some of the rollers are engaging'full spools, or spools having larger amounts of yarn the on which are turned easily by pullof the yarn, t e rollers engaging these spools will assist the rollers engaging spools having lesser amounts of yarn thereon and relieve them, so that the yarn will be de- .ad livered from off all the'spools at a substantially uniform tension. 4

The yarn drawn from the spools passes through a pattern reed 2l to separate and space the yarns, and serve as a common junction for all the yarns on all the spools. The pattern reed,- may be mounted in any suitable manner on the frame ofthe machine. Y I I'he sheetof varn drawn from the spools i is led over a roll 22 suitably mounted on the frame on themachine, thence under a takeup roll 23 to which attention will later be directed, and thence through feed rolls 24 amr 25 which provide-a direct and Ipositive feed for drawing the yarn from 1 the'spoolsv i.

The feed rolls are mounted .in bearings 26 on the frame of the machine. The roll 25 is driven through belted connection 21'by Va motor 28; and |the feed roll 26 is driven .from oil' the feed roll 25 through geared connections 23.

Inasmuch as the yarn will be withdrawn from I the, spools and fed at a relatively high speed by the operation of the feed rolls it becomes necessary when thg feed is stopped to prevent continued rotation of the spools by'reason of their momentum which would .cause disarrangement and tangling of the yarns'. The immediate braking elements for 'stopping rotation of the spools are the traction rollers 1 whichhave constant bearingA against the spools, and this by Stopping rotation of these rollers. Rotation of the rollers 1 is stopped by braking elements-inthe mechanism interconnecting the rollers. To this end one of the shafts l2, and preferably the one adjacent the lowermostspool on the creel bearsfriction disks or wheels 36 which are keyed to the shaft. Arranged to engage the peripheral surface of each of these disks is a braking shoe 3i, having a pivotal attachment 32. Each shoe is normally y maintained in an inoperative position out of contact with its complementary friction disk bya spring 33. On the application of force to overcome the tensions of the springs 'and draw the 4 brake shoes into contact with the friction disks the mechanism interconnecting the rollers 1 will. be stopped.V In onsequence rotation`of the rollers 1 will be stopped, so stopping rotation of the spools. The takeup roll 23 beneath which the connections 39 which pass through conduits 40 and connect with the ends of the brake shoes 3i', for overcoming the tension of the springs 33, and drawing these shoes into braking contact with. the friction disks 36 when pivoting of the'levers 31 raises the arms 38 of these'levers. The armsy 38 of the levers are raised when the feed stops for thereupon the takeup roll 23 will drop inasmuch as the sheet of yarn will continue to come from .the spools ldue to their momentum, permitting th'e roll 23 to drop and continuing until the roll has so far dropped as'to raise the arms 38 of the lever sumciently to apply thebrakesand stop the operation of the spools. I'he takeup roll 23 may be a roll of some considerable weight, but`it is preferred that quick drop of this'roll, when slack occurs in the yarn sheet 'dueto stoppage of the feed, shall occur by weighting the arms 36 of the levers on which the roll is mounted. To this end the levers are preferably provided with end extensions M on which weights 42 are hung, desired variation being attained by adding more or lessiof theseweights.

After passing the feed the yarn is directed to pass through a lease reed 45, thence through a section reed t6, and is then wound upon the Adrum 2. This drum is one of a common type mounted upon a shaft I8 arranged to turn in side frames 49. 'I'he drum is provided with separated into sections within which the -yarn is wound. The frames bearing the drumare prothe customary pins 56 by which its exterior -is vided with wheels 5| arranged to run upon tracks v52 alongwhich the drummay be moved, and its various sections broughtY into proper alignment lfor winding. At its ends the drum is provided with pulleys 54, around which are passed belts 55from'nff illeys 56 keyed to a rotary shaft 51,

the ends of which are journaled to turn in the frames Aat either end of the drum. Ihe rotation of the shaft 51 rotates the drum through the' belted connection therewith. Any suitable belt tighteners 58 'are provided for taking up slack in the belts. Power is applied for turning the shaft 51 by means ofa motor 60 arranged upon the slde, of t e frame I9, and to'which frame is also a1-v fixe a'motorkc'asing 6I. 62 Vrepresents the motor key 69 to the shaft 65. Arranged, also, upon the shaft is a clutch member 10. 'Ihis clutch member is provided with' an elongatedhub or sleeve 1I which embraces the shaft. The interior of this hub or sleeve is provided with a slot 12 adapted to receive akey 13 projecting from thev shaft 65 and by means' of which the clutchmember is made to turn-with the shaft but is longitudinally movable thereon. Interpose'd between .the two clutch members is a rotating sprocket 15 which turns freely upon the shaft 65, ball bearings 16 being interposedbetween it and the shafts The Sides of the sproeket'15 adjacent-its peripheral edge are faced with friction rings 18 against which the lclutch members have bearing. The sprocket has sprocket chain connection 80 with a sprocket gear 8| on the end ofthe shaft 51. Arranged upon the hub 1I of the clutch member 18 is a lspring 82 one end of which bears against the outerside ofthe clutch member 1li and the other `end of which bears against `a thrust roller bearing on the face of an internally threaded nut 85. 'I'his nut is arranged to lturn upon a threaded plug 85 carried by abracket 81 on the motor casing. vAs the nut 85 is turned upon the threaded plug 86 the nut is moved in the longitudinal direction of the shaft and exerts pressure to compress the spring 82. The nut 85 is turned through connection with a worm 88 arranged upon a rod 88 which turns in bearings 80 onthe frame of the drum and is turned by a hand'wheel 9|. By means of the hand wheel the gear 85 may manually be moved to compress the spring 82 and thereby bind the sprocket 15 between the two clutch members 56 and 10 whereupon the sprocket 15 will move with the shaft 55 and turn the vdrum through the-interposed chain and belt connections before referred to. If the resistance oiered by the drum for turning exceeds the frictional' resistance between the clutch elements and the sprocket 15 then the drum will not be turned. The resistance offered by the drum to turning will n depend essentially upon the tension of the yarn wound vupon the drum. Accordingly, by varying the applied pressure of the clutch members upon the sprocket 15 any desired tension may be placed upon the yarn so that-itwill wind upon the drum with a substantially uniform tension.
