WINDING MACHINE.

Application filed January 28, 1914:. Serial No. 815,088.

To all whom itamag concern.

Be 1t known that I, E WARD JAMES Asno'r'r. a citizen of the United States, and

resident of lVilton, in the county of Hillsborough and State of New Hampshire, have invented new and useful Improvements in Winding lllachines, of which the following 18 a specili'cation.

Jliis invention relates to Winding machines for winding yarn or thread from pne package on to another of more convenlent form or size. The invention is apphcableto winding machines generally, but it is believed that its largest utility is it connection with winding machines for winding yarn, either in single or multiple ply from the relatively small spools or bobbins upon which it is spun or twisted, into a larger package, usually termed a cop yarn reaches the detector.

er cheese, which affords a more suitable supply for making various textile products. Such cop or cheese is a package of yarn built up on a suitable yarn receiver, such as a paper or wooden tube or cons made without heads at its ends, the package being held I together by the self binding cross-winding of the yarn as it is laid on. Usually such cop or cheese measures about six inches in length and about six inches in diameter, and requires several bobbins of yarn to make it.

lathe winding machine herein illustrated, "which is an example of winding machines in general use, as in all winding machines of. this type, it has heretofore been necessary for the operator to remove the bobbin supplying the cop, when the bobbin is empty, and to replace it by a fresh bobbin, tie up the ends, and restart the machine, which is usually stopped automatically when the yarn is exhausted from thebobbin. Machines of this character have also been provided with a slub detector which automatically breaks the yarn and stops the machine when a slub, knot or other bunch in the In such case it has heretofore been necessary for the operator to remove the slub, tie up the ends, and restart the machine.

These operations require in the aggregate a great deal of time and constant attention and labor on the part of the operator in keeping the machine in operation.

The present invention consists 1n applying to a winding machine mechanism which will operate automatically when the supages to the winding mechanism ceases, to attach the leading end of the material of a new bobbin or package to the following end of the material passing to the winding mechanism.

As one of the principal uses of. the invention is for winding cops or cheeses from bobbins of yarn, I will, for the purpose of illustration, address the description to a winding machine of usual form, and for convenience, will use the terms cop or cheese for the package being wound, yarn receiver for the spool, cone or other device on which the material is being wound, and bobbins of yarn for the packages of material from which the cop or cheese is supplied. It will be understood, however, that the invention is not limited to any particular form of wound package nor any particular form of supply packages, and that these terms whether used in the'specification or claims are intended to designate generically the class of articles of which they are specific examples.

In the preferred form of my automatic. yarn replenishing device there is combined therewith means for automatically stopping the machine when the supply of yarn ceases and for restarting the machine after the supply of yarn has been replenished.

Another feature of the invention, not limited, however, to use in conjunction with the yarn replenishing mechanism although it is preferably so used and is herein shown as so used, resides in the provision of automatic mechanism for removing slubs or other bunches from the yarn as the latter passes from the source of supply to the cop or cheese which is being wound. This mechanism comprises a detector for the slub or the like, mechanism to stop the winding operation when the slub appears at the de tector, mechanism to remove the slub, mechanism to attach together again the severed ends, and mechanism to restart the machine after the slug has been removed and the ends left by its removal have been tied together. Said slub detecting and removing mechanism is the subject matter of a separate application now Patent No. 1,311,788, dated July 29, 1919.

Bythe foregoing improvements I have eliminated the greater partof the manual labor and attention on the part of the open ater heretofore required in tying in new bobbins when the bobbins being wound are exhausted, and in taking out the slubs, which work it is estimatedhas amounted to at least 25% of the whole cost of manufacturing the yarn and preparing it for the warp beam of a loom, or other machine using it.

Figures 14, 15 and 1.6 are partial diag "ammatic and sectional views illustrating the relation of the old and new threads or strands to the mechanism at various stages of the operation, as hereinafter exjjilaincd Referring to. the drawings, 1 represents the usual holder for the quill or other yarn receiver 2, on which the yarn or thread 3 is wound into a cop or che 1. The cup or cheese 4 rests upon a drum 5 and is driven by frictional engagement of the drum with the surface of the cop. The drum 5 is lined to a shaft 6 which is driven through the usual n'iechanism, not shown, froin the main shaft Yet the machine. The main shaft 7 is also connected by the usual mechanism, not shown, with the usual cam shaft 8 which carries a cam 9 for actuating thread-guide 10. The foregoing parts are of the usual construction, and it, will be understood that the thread-guide 10 is recharocated lengthwise of. the cop onits guide-rods 11 and 12 by means of cam 9. while the cop-1 is rotated by the drum 5. The mechanism thus far described is an example of winding ina chines in common use, and may if desired also include the usual autou'iatic device. not

herein shown, 7 for stopping the windingoperationwhen the cop has grown to a p:e determined size. v

The yarn is supplied tolthe cop or cheese 4 from a supply carrier, herein showiras a rotatable creel 13 (Figs. 1, 4, and 5'), which is provided with a series of spindles 14 in annular arrangement on the upper side of the creel to receive a plurality of bobbins of yarn or other supply packages 15. The creel 13 as herein shown consists of a circular table rotatably mounted on a central hollow post 16, which is fixed at its lower end in a socket at the top of bracket 17 and therein fastened against rotation by a pin 18. The post 16 is made hollow to receive the wiring for one of the electroniagnets hereinafter described. To the hub of creel 13 is fixed the lower end of a sleeve 19 surrounding the post 16 and carrying at its upper end a hollow cylindrical head 20 A flange or ledge 21 is provided on the interior of the cylindrical walls of the head 29, formed on its upper side with ratchet teeth 22, cooperating with a dent 23 which normal- 1y rests on the top of flange 21 in the path of the teeth 22. Upon the upper end of the post 16 is mounted. a bracket 24 fastened to the post by a. pin 25, which also serves as the pivot for detent 23. The bracket 24. is made with a laterally extending arm 26 at its upper end, and an electromagnet 27 is secured to the under side of arm 26. The detent 23 constitutes the armature of said electromagnet. lVhen the magnet 27 is energized it swings detent 23 upwards on its pivot pin so as to carry its free end out of the path of teeth \Vhen de-energized the magnet releases the detent 23 and the latter falls by gravity upon the toothed flange 21;. At the lower end of the bracket 24 is an annular flange 28, to the under side of which is fastened' a segment 29 of insulating material, carrying on its under side a detector segment 30. The detector segment 30 extends beyond the periphery of flange 28, and this project ing margin of the detector segment coopeu ates with a series of yarn-controlled detector contacts 31..

Each yarn detector contact 31 is pivotally mounted within the hollow head 20 at 3 F ig. 1) and has an arm extending radially outward througl'i a slot 33 in the cylindrical wall of head 20. The inner arm ofeach detector contact 31 normally occu pies a position immediately below the conductor segment 30 and is made lighter in weight than the outer arm. Each detector contact 31- is also provided with a laterally projecting stud 3e1- l'lavinga nut 35 threaded on its outer end, which serves as an adjustable abutment for a spring 36 surrounding the stud. The inner end of spring 36 bears against a clamping plate 37 fitting into a recess provided at the side of the detector contact Directly above each detector 31 there is athread-gluide 38 projecting radially from the, exterior. of, the head 20. and above. each threadguide, extending radially from. the

head 20 is a radially extending hitching post 39, A yarn detector 31, thread-guide 38 and hitching post 39 are provided for each of the spindles 14 and bobbins 15, and the thread from each bobbin,- excepting that from which yarn is being supplied for the time being to form the cop or cheese, extends upwardly between its appropriate detector 31 and clamp plate 37, thence through the thread-guide 38 above said detector to the hitching post 39 above said thread-guide, where the end of the yarn is wound a few times around the post 39 so that the stretch of yarn between the detector-31 and the post 39 will be held taut for the purpose hereinafter explained.

The creel 13 rests upon a friction washer 40 of leather, fibre or other suitable ma terial, below which is a beveled gear 41 loosely journaled on post- 16 and supported on the top of bracket 17. The bevel gear 41 is continuously driven by a bevel gear 42 fast on shaft Scarrying atone end a pulley 44 (Fig. 1), which pulley is con nected by a belt 45 with the pulley 16 on main driving shaft 7. The continuously driven gear 41 through the friction washer 40 tends to rotate creel 13 in the direction of the arrow in Fig. 2, but is normally held against rotation by engagement of the detent 23 with one of the teeth of flange .21.

When the creel is thus rotated, the taut vertical stretches of yarn held by the detectors 31 and posts 39 are successively pre sented to the knot-tying and cop-controlling mechanism indicated generally at 17 in Fig. 1, through which the yarn passes from the supply bobbins to the cop or cheese 4. The outer ends of all the detectors 31, excepting the detector of that bobbin which for the time being is supplying yarn to the cop or cheese, are held elevated against the upper edges of their slots 33 by the engagement of their clamps 37 with the yarn, while the outer end of the detector of the bobbin which is supplying yarn to the cop or cheese is also held elevated, but in this case by the draft of the yarn which is moving upwardly be tween the arm 31 and clamp 37. Thus it will be seenrhat said arm and clamp constitute a combined detector and tension device for the yarn.

Upon'the exhaustion of the yarn on any of the bobbins from which the cop or cheese is being supplied, the relatively'heavy outer endof the detector arm 31 drops downward carrying the inner relatively light arm into contact with the conductor segment whichcloses the circuit through the electromagnet 27. hilagnet 27 thereupon lifts detent 23 out of engagement with ratchet teeth S22, allowing the continuously rotating gear 41 to rotate the'creel in the direction of Y the arrow through the friction disc 40, the

1 \,Lm\.L

As the creel 13 rotates and a full or fresh v bobbin is brought into operative position with relation to the mechanism 47, the inner end of detector arm of the empty bobbin reaches and passes upward through one of the gates in segment 30, as shown in dotted lines in Fig. 4, thus breaking the circuit through the magnet 27. This causes the magnet which is now deenergized, to drop the detent 23 in time to engage the next tooth 22 on flange 21, thereby stopping further rotation of the creel.

The following edge 116 of the last gate 51 constitutes the leading end of another ring segment 117, secured to the uncer side of the flange 28 and insulated therefrom. Segment 117 is out of contact with segment 30. The leading end 116 of segment 117 is bent upwardly to form a cam surface lying in the path of the inner'arms of detectors 31 when the latter occupy their dotted line position shown in Fig. 4. When any elevate-"l inner detector arm is moved past the gate 51, it is engaged by the cam end 116 of segment 11? and swung downward into normal position below the flange 23, thereby swinging the detector arm '31 again to normal positio-n.

The mechanism indicated generally at l? in Fig. 1, is shown in detail in Figs. 7 to 11 inclusive. This mechanism comprises a box-like frame 52 mounted on the machine frame, in which is journaled a hollow shaft 53 which carries three cams 54, 55 and 56, and also a gear 57. The hollow shaft 53 is normally at rest, but when actuated as presently to be described, it makes one revolution at the completion of which it is automatically stopped. Through hollow shaft 53 extends a continuously rotating shaft 57 on which is fixed a ratchet wheel The shaft 57 is driven by a pulley 59 (Fig. 1) connected by a belt 60 with a pulley '61 fast on the main driving shaft '7. The ratchet wheel .58 cooperates with the pawl 62 pivoted to the cam 54. Said pawl 62 is normally held out of engagement with the ratchet wheel by a hook 63 at the lower end of connecting rod The lower end of the connecting rod 61 is normally held so that its hook 63 supports the pawl 62 in inoperative position by means of a latch 65 pivotally supported by a pintle 66 on the frame 52, and a link 67 pivotally connected cheese rests on the driving drum 5.

to the, lower end of the rod 64 at 68, and at its upper end pivotally connected to the frame 52 at 69. lVhen the latch 65 is disengaged from rod 64, the rod is shifted endwise by a spring in the direction of the ratchet wheel 58, thereby permitting the continuously rotating ratchet wheel to pick up the pawl 62 and carry the latter together with the cam 54 and shaft 53 around with it. The lower end. of the rod (34 is forked, and within the fork is mounted a roller 71 engaging cam 54, so that at the completion of one revolution of the shaft 53 and cam 54 the latter pushes the rod 64 outward, thus carrying the shoulder 72 on the rod past the nose of the latch (55 which drops into place under the shoulder and locks the rod 64 again in its original position with the spring 70 under tension. \V hen rod 64: is thus lifted, its hook 63 draws pawl 62 away from the ratchet wheel 58, thereby stopping further rotation of the shaft 53.

To operate the latch (35, a notch 73 is provided which is occupied by the free end of an armature 74 pivoted at 75 on the frame 52. The armature 74; is operated by an electromagnet 7 6, whose winding is in series with electromagnet 27 within the creel head 20, so that whenever a yarn detector 31 drops and closes the circuit through electromagnet 27, the electromagnet 76 will be simultaneously energized, whcreu1'ion the armature 7 4. will be raised, lifting the pawl 65 and releasing the rod (if at the same instant when the creel 13 is freed from the detent 23.. Thus when the supply of yarn ceases from a bobbin, which for the time being is supplying the cop or cheese, the mechanism is automatically operated, which occasions the step-movement of the creel to present a fresh bobbin to Operative position and to cause one revolution. of the shaft 53, which in turn stops the winding mechanisn'i and operates the knot-tying mechanism for connecting the leading end of the fresh bobbin with the following end of the yarn passing to the winding mechanism in the manner hereinafter described. 7

Referring now to Figs. 1 andv 2, it will be seen that the upper end of rod 6% is ].)ivotally connected to one end of the cylinder segment or shield 77 loosely mounted on shaft 6 and partially surrounding the driving drum 5, said segment being normally held by the rod 64: so that the cop or lVhen rod (if is freed from latch 65 and shifted endwise as described by spring 70, the segmental shield 77 is swung on shaft 6 into a position between the cop and the driving drum 5. thereby lifting the cop out of contact with the driving drum and at the same time acting as a brake to stop the rotation of the cop. Therefore, whenever the shaft 53 starts upon its single rotation, the rotasimultaneous advance or movement of the creel one step, the rotation of shaft 53 and stoppage of the winding. When, however, the machine acts to detect and remove from the yarn a slub, as presently to be described, only magnet 76 is energized, thereby stopping the winding mechanism andactuating the knottying and slub-removing mechanism but leaving the creel 13 unaffected.

The slub detector is shown at 78 and comprises a normally horizontal arm 79 and a relatively heavy upright arm 80 which acts as a counterweight. The detector 78 is pivotally mounted upon but insulated from rod 81 fixed at its ends in the frame 52. The weight of arm 79 is sufficient to hold the detector normally against a stop 82 of insulating material projecting from the frame 52 while the free end of the arm 79 occupies a cooperative relation with the abutment 83, also of insulatii'lg material fixed to the frame. The yarn from the bobbin or bobbins supplying the cop passes from the creel through the clamp at the outer ends of the yarn detector arms 31, thence through the guiding eyes 38, and thence over a guiding pin 118 (Figs. 7 and 10) and between the aluitment 83 and the slub detector arm 79. From the slub detector yarn passes upwardly over a lUOP-fOI'lDlllg' guide in the form of a porcelain knob or roller 84, carried by and projecting from the side of a sprocket chain 85. From the loop-forming guide 84; the yarn passes downwardly around an arm 86 and througlra. guiding eye 87 fixed to the frame 52, and thence to the thread-guide 10 of the winding mechanism.

When a slub or other bunch in the yarn strikes arm 79 of the slub detector, the latter is thrown backward until the arm 80 over balancing the arm 79 makes contact with the hollow shaft 53, thereby closing the circuit through electromagnet 7G stopping the rotation of the cop 4c and causing the shaft 53 to make a single rotation, as above described, without actuating creel 13. This revolution of the shaft 53 acts through mechanism to be described, to remove from the yarn a length or section containing the slub. to tie together the severed ends of the yarn formed by the removal of the slub, and to restart winding. As the shaft 53 approache's'the completion of its single revolution the cam blower or other suitable device, so that a strong current of air is constantly flowing upward through the hollow casing 88. The chain 85 above referred to carrying the loopforining guide Se is mounted on two sprocket wheels 91 and 92, the former being journaled on a shaft near the upper end of the tubular casing 88, and the lower being fixed to shaft 94: which is journaled in bearings on the frame 52. The shaft 94: carries a pinion 95 (Fig. 7) at one end in mesh with the gear 57 on hollow shaft 53. The ratio between the gears is such that when the shaft 53 makes one complete revolution the sprocket wheel 92 will be driven, in the direction shown by the arrow in Fig. 7, a sufficient distance to move the chain 85 once completely around its path so that the loopforming guide 8% will niake one complete circuit and stop at the point from whlch it started. Normally the guide 84 on the chain occupies the position shown in Fig. 1 at 0?, so as to maintain a loop of considerable length in that part of theyarn passing from the supplybobbin to the cop, whlch is between the detectors and the tying and out ting mechanism.

The arm 86 is'loosely mounted on a ve"- tical rock shaft 96, but is connected with saidshaft through a spring 97 which normally tends to hold the arm 86 against a stop pin 102 on the arm 52. The rock shaft 96 carries a pair of arms 98 and 99 one above "the other, and at its lower end carries a laterally projecting cam roll100 which is held against cam 56 by a spring 101 connecting a lever on arm 99 with the frame 52.

When the creel 13 is actuated as described to advance one step, one of the taut stretches of yarn on the head 20 of the creel is carried between abutment 83 and arm 79 of the slub detector and-between. the two arms 86 and 98 behind the arm 99. Tininediately thereafter the cam acts through cam roll 100 to rock the shaft 96 and swing the two arms 98 and in the direction of the mechanism 417 so as to carry that stretch of the yarn which extends between said arms into the same path as the active or old yarn running about guides 86 from casing 88 or guide 84, and to take both old and new yarns into position to be acted upon by the knot-tying and yarn-severing devices.

During the first part of. the movement of the arms 98 and 99 the arm 86 will 'be held against stop pin 102 by the spring 97, so that the arms 98 and 86 will be closed together to clamp the yarn between them, after which the continued movement of arm 98 will swing the arm 86 with it as a single part to the limit of movement in the direction of the knot-tying and severing devices.

Referring now to the knot-tying and yarn-severing devices contained in the head 17, 103 represents a bushing fastened by a screw 104 in a hole provided therefor in the frame 52. lVithin this bushing 103 is journaled a stem 105 of the knot-tier and yarn cutter. A longitudinal slot is provided in the operative end of said stem in which is arranged a yarn-cutting and gripping blade 107. The blade 107 is pivoted at 108 in the fork of the stem 105, and is made with a tail-piece 106 which works in an eccentric or cam-like recess 107 in the end of bushing 108, so that as the stem 105 is rotated the said eccentric recess acts to swing the blade on its pivot 108 to open and close the blade with relation to the fingers at the end of stem 105. At the opposite end of stem 105 is fined a pinion 109 which is driven through an intermediate gear 110 by the gear 57 on shaft 53. The operative end of stem 105 is made with two obliquely disposed tapering fingers 111 and 112, one at each side of the blade 107. Finger 112 cooperates with the sharp or cutting edge 1130f blade 107 to cut the yarn when the blade is closed with relation to the fingers, and the other finger 111 cooperates with the rounded edge 114: of the blade to clamp the yarn between the blade and finger 111 when the blade is closed Normally the oblique fingers and blade occupy the position best shown in Figs. 10, 11 and 13 which is diametrically opposite to the position which they will occupy when the arms 86, 98 and 99 swing the yarn into cooperative relation with saic tying and cutting mechanism. The arrangeinent of the cams and the action of the parts is so timed that after the creel has brought a new bobbin into position, and the a1 ms 80, 98 and 99 have swung the taut stretch of that bobbin and of the old or previous yarn into cooperative relation with the stem 105, the latter has been rotated to a position such that the arms 98 and 99 lay the taut stretch of the yarn against the stem 105 within the acute angle formed back of the fingers 111 and 112. At the end of the next quarter revolution of the stem 105 and while the fingers 111 and 112 are passing the seretch of yarns extending from the stem 105 to the arm 98, the blade 107 is held closed by the cam recess 107 so that as the fingers 111 and 112 pass that seretch of the yarn, the yarn is engaged by the outer sides of the fingers and'deflected around the end of stem 105.

At the end of one complete revolution of the stem 105 the yarn has been wound one turn around the stem close to the bases of the fingers 111 and 112.

During the next or fifth quarter of the revolution of stem 105 the fingers and blade 107 reach that stretch of the yarns extending from stem 105 to the arm 99 and the blade 107 occupies its most open position so that continued movement of the stem lays the yarns into the V-shaped opening between the blade and the fingers and thereafter closes the blade upon the yarns, the sharp edge of the blade severing the yarns between the blade and arm 99 and the other edge of the blade clamping the ends of the yarns coming from the knot which is being formed. As the stem starts the last half of its second revolution and while the blade is still closed, the arms 86 and 98 stop and start to move back toward their normal positions, and in so doing pull upon the yarns extending from said arms to the knot and act to pull the knot off from the stem and fingers and to draw it tight. As the stem approaches the latter part of its second revolution the blade 107 is fully open and the tied ends of the yarn are left in the grip of the arms 86 and 98 which are moving backward toward their normal po--- sition.

During these operations the sprocket chain will have been actuated by gear 57, intermediate gear 110 and gear 109 on the sprocket shaft 94, to make one complete revolution. The parts are so timed that as arm 86 strikes stop pin 102 and arm 98 moves away from arm 86, the loop-forming guide roller 84 on the sprocket chain will pass upward between said two arms (see Fig. 8) and pick up the yarn. After picking up the yarn the guide roller 84 iscarried to its normal position by the sprocket chain, forming a new loop which extends upward into the tubular casing 88 as above described. The purpose of this loop is to provide a sufficient length of yarn between the detectors 31 and 7 8 and the roller guide 84, and between said guide 84 and the bottom of tubular casing 88, to prevent the end of the yarn which is passing to the cop or cheese from moving out of the lower end of the tubular casing 88 and out of the range of the knot-tier before the rotation of the cop is stopped by the action of the yarn detectors 3], and in the case of operation to remove a slab, to insure that the slub detector 78 will stop the machine while the slub is somewhere in the loop which occupies the tubular casing 88 when the movement of the yarn ceases. I It follows, therefore, that whether the winding mechanism is stopped by the exhaustion of the yarn through the operation of the yarn detector 31, or'by the appearance of a slub through the operation of the slub detector 78, the yarn end or the slub, as the case may be, will be within said tubular casing 88. If the winding mechanism is stopped by the exhaustion of the yarn, the following end of the yarn will be held up within the tubular casing 88 bythe air draft therein. When the creel is actuated to brin the leading end of the yarn of a fresh bobbin into tying position, said leading end is thus brought along side of the following end of the yarn passing to the winder about arm 86, Whether or not the exhausted or broken end is supported in the tubular casing 88 by the air current only, or is long enough still to extend around roller 84 and past the arms 98 and 99, and the knot-tying mechanism will act upon the new and old strands to unite them by tying in the knot as above described as if they were one strand. 7

When the blade 107 severs from the knot formed on stem 105, that portion of the yarn or yarns which is held above it in the tubular casing 88, the severed portion is carried off by the air current through-pipes 89 and 90. v

In case the winding operation is stopped through the slub detector 78 the slub will have reached some point in the loop held up within the tubular casing 88 by the loopforming guide 84, and while in such position the arm 98 and the knot-tying mechanism will operate respectively to bring together and to tie the two legs of the loop together, and then sever from the leading and following portions of the yarn thatsection of the loop containing the slub above the knot, said severed section being carried oil through pipes 89 and 90, while the roller guide 84 on chain 85 will descend to pick up the reunited yarn and again rise to form a new loop ready for another operation.

The guide eye 87 is offset from the chain 85 as best shown in Fig. 11, so that the length of yarn between arms 86 and said guide eye will not be picked up by the loop-forming guide 84 during its downward movement.

If only a single strand of yarn or thread is to be wound upon the cop it will be sufficient if there is a single conductor segment 30 and gate 48 to break the circuit through the electromagnet. In such event, however, the gate 48 should be made sufliciently wide so that the detectors 31 will remain in the gate for several steps in the movement of the creel. It is the practice, however, often to wind two or more strands of yarn simultaneously upon the cop or cheese, and for this purpose I provide va plurality of angularly separated gates 48, 49, etc., as shown. When winding-two strands, for example, one supply bobbin will occupy its regular running position directly under the slub detector 78, While the secnd supply bobbin will be the next bobbin on the creel in advance of the one under the slub detector. The thread or yarn from the second bobbin will extend from its guide 38 around the guidepin 118 where it will join and pass upward alongside of the yarn from the first bobbin. Under these conditions the draft on the two upwardly movingstrands of yarn holds their respective detectors 31 elevated, and when either yarn runs out or when a slub appears in either yarn, the yarn detector or the slub detector as the case may be, will act as already described to tie in a fresh strand of yarn or to cut out the length of yarn containing the slub, and retie the ends. It will be understood that where several strands are thus used they all lie side by side and are acted upon by the tying and cutting mechanisms as a single strand,

In Figure 12 I have illustrated diagrammatically the wiring and electrical connections for controlling the mechanisms here inbefore described. The battery or source of electrical energy is shown at 122. One pole ofthe battery 122 is connected by a wire 119 with one end of the winding of electromagnet 76. The other end of the winding of electromagnet 76 is connected by wire 120 with one end of the winding of magnet 27. The other end of the winding of magnet 27 is connected by wire 121 with the conductor segment 30. The opposite pole of battery 122 is connected by wire 123 with the 'rame of the machine, on which the shaft 53 and detectors 31 are grounded. The slub detector 78 is insulated from the frame 52- and is connected by a wire 124 with the wire 120. t will thus be seen that when the detector 78 is operated by a slub and makes contact with the hollow shaft 53, the circuit is closed only through magnet 76, but when the detector 31 is opeated by the exhaustion of the supply of yarn and makes contact with conductor seg ment 30, the circuit will be closed through both magnets 76 and 27.

The relation between the thread or yarn and the parts of the mechanism acting upon the yarn at various stages in the operation above described, is shown diagrammatically in Figs. 14, and 16. F 14 illustrates the'condition of things when the yarn has run out from a bobbin, the material passing from arm 86 to the winding machine being designated as active thread, the yarn end still in casing 88 being designated as eX- haust end, and the bobbin from which said yarn has been drawn being designated empty bobbin. The detector 31 has fallen to operate the mechanism for turning a new or full bobbin into place. Fig. 15 shows the position of the parts when a full bobbin has been turned into running position, with the leading end of its yarn alongside the exhaust end of the preceding strand ready to be tied. And Fig. 16 shows the knot tied, the clamping arms again opened, and the loop-torming guide roller er starting; from the lower end of its travel to rise and draw up a new loop in the tied yarn. The cut off ends will at this stage have been drawn away by the air suction in casing 88.
