CHARLES D. REYNOLDS, OF CRANSTCN, RHODE ISLAND.

WlNDI'NG-MACHINE.

Application filed ctober 5, 1916.

To all whom t may concern.'

Be it known that l, Cnnnnns D. REYN- oLns, a citizen of the United States, residing at Cranston, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Vil'nding-ldachines, of which the following is a specification.

lily invention relates to winding machines and consists of improvements in the construction and method of operation of the same. The objects of my improvement are to simplify the mechanism of the machine by reducing the number of its parts; to reduce the weight of the parts to provide for high-speed operation, and also for the sake of economy in cost of manufacture; to compact the mechanism within a minimum compass to save floor space, and to otherwise render the machine more eihcient in operation and more durable in use as more 'fully pointed out hereinafter.

The manner and means for carrying out the improvement are fully described in the following speciiication, illust-rated by the accompanying drawings, in which like reference characters designate like parts. ln the drawings :-u

Figure 1 is a side elevation of one of the component units or heads of the machine, illustrating the essential elements of the wiheling-mechanism and the manner in which it is mounted on the longitudinal frame or bed shown in section;

TReferring lirst to Fig. 1, 2 designates the troughlike frame or bed of the machine which is supported in horizontal position on suitable legs or standards, not here shown, and on which is mounted any desii-ed number of winding units or heads. The bed 2 is constructed with overhanging side-flanges 3 on which the framework of the heads rests, and as here shown its bottom is left open to receive a dished drippan et supported on inwardly projecting Specification of Letters Patent.

ledges 5. Set into the bed 2 are a series of casings 6 spaced at intervals along the .maenine to inclose the traverse-mechanisms for the several winding units or heads. As all cf the heads are of the same construction and arrangement, only one is herein shown and described, and it will be understood that as many units asprequired may be applied to the bed 2 in accordance with the length to which it extends. As shown in Figs. 1 and 2, the casings 6 are constructed in the form of narrow, semi-cylindrical boxes having relatively thin sidewalls 7 and projecting flanges 8 at the top overlapping the horizontal side-flanges 3 on theV bed 2, to which they are secured by bolts 9. Journaled in alining bearings 10 at the ends of the bed 2, see Fig. 2, and eX- tending through openings in the sides 7 of the casings 6 is a horizontal cam-shaft 11 which reaches the whole length of the machine. The shaft 11 is driven from a belt or other suitable means at one end, the driving connections not being here shown or described as they may be of any well known arrangement. The shaft 11 carries a plurality of heart-shaped traverse-Canis 12, which are keyed thereto at 13, see Fig. 1, to adapt them to revolve in the casings 6, the latter serving as oil-reservoirs therefor.

The opposite side walls 7 of the casings 6 are flanged at the top at A and milled olf along their upper edges to provide the parallel. finished faces 15. Extending along the flanges 14 are cleat-like strips 16 bolted to lugs 17 on the casing 6 by means of the screws 18, see Figs. 1 and 2. rlhe cleats 16 overhang the finished faces 15 of the casing 6 with a space therebetween to provide the opposite slots 19 in which a reciprocating crosshead or traverse-slide 20 is adapted to slide. If preferred, however, the slots at the top of the casing 6 could be cut in its sides without requiring the upper cleats 16, the arrangement shown being designed more particularly for convenience in constructing and assembling the parts. As illustrated in Figs. 1. 2 and 5, the slide or crosshead 2O is preferably constructed of sheet-metal bent up in substantially cradleshape to render it staunch and strong While reducing its weight to adapt it for highspeed reciprocation. Its opposite, longitudinal sides 21 are joined at the ends by horizontal cross-strips 22, see Figs. 2 and 5, from i position while allowing it to slide vertically which depend ears 23. Extending between the ears 23 are lateral bearing-pins 24 carrying rolls 25which are-adapted to ride on the opposite sides of the peripheral face ot the cam 12. Projecting from the sides 21 of the slide 20 are horizontal ears Or runners 26 fitted to the slots 19 in the casing 6 to adapt the crosshead to slide therein when the'cam 12 is rotated with the rolls 25 tollowing its eccentric face. The reciprocating slide 2O is adapted for connection with a pairof pivoted traverse-levers 27, only one being here shown, to oscillate the latterv tov traverse the thread-guides ot the machine in the manner as next described.

Each cam 12 is arrangedV to operate the traverse-levers` for two adjacent windingheadsl or units, butas the connections for both levers are thc same, only one is herein shown and described. Referring particularly to Figs. 1 and 2, the cam-casing 6 has attached to its under side a hearing-member 28 secure-d thereto by the screws 29 or in any other convenient manner. Extending upwardly from the member 28 are two elbowed arms 30 'formed at the top with bearings 31 for the pivot-shafts 32 of 'the traverse-levers, only one oi' which is shown in the drawings. The inner end of the pivot-shaft 32 abuts the end of a lug 33 on the side of the. casing 6 to locate it 1n position 1n its bearing 31 and a set-screw 34 secures it in place. The traverse-lever 27 comprises two telescopic parts, one slidable longitudinally of Athe other to provide for extending the length of the lever for Va purpose as later described. VThe heel or pivot portion of the lever 27 is or' forklike construction comprising two

arms

35, 36

mounted on the projecting ends of the shaftl 32, straddling the bearing 31. Slidably fitted to the arin 36 is the longer, extensible portion 37 of the lever 27 which is preferably constructed of sheet-metal for the purpose of reducing its weight, see Fig. 2. At its lower end the extension 37 is formed with wings'38 bent to overlap the sides or" the arm 3G to adapt it to slide longitudinally thereof and its main portion is slotted at 39 to provide a clearance for the pivot-shaft 32, see Fig. 5. Bent at right-angles to the vertical portion of the lever-extension 37 is a finger 40 projecting across the top of the arm 36 to adapt it to limit the downward movement of the extension on the arm, see Fig. 2. A coiledV spring`41 is hooked into the end of the i'inger 40 and anchored at its lower end to a hook 42v on the arm 36, thereby tending to maintain the extension 37 in its retracted.

upward in the manner and for the purpose as later explained. AReferring to Fig. '5, the extension 37 of the lever 27 takes the forni Y k1oi" a sickle-shaped loop at 43 to adapt its side to elearthe cam-shaft 11 as it oscillates back and forthacross the axis thereof. Be-

yond the loop-portion 43 the extension 37 is formed with an upright arm 44 in line with its pivot-ar1n'36. .Secured to the side of the arm 44, or formed from a cut-out Yportion of the metal thereof, if preferred, is a. linger 45 which serves as an outer sup- Aport for a pin 46, see Fig. 2, driven through the arm. Journaled on the pin 46 is a roll '47 which is adapted to ride on the upper edge of the side 21 of: the crosshead 2O as shown in Fig. 5; or to engage a slot 48 therein as'illustrated in Fig. 1. The slot 43 is formed with a marginal ange 49 to provide a more extended bearing surface for the roll 47, thereby increasing the durability of the engaging parts. lt will be understood that the slide or crosshead 20 reeiprocated continuously from the earn l2 and when the roll 47 is engaged with its slot 148 the traverselever 27 will be oscillated thereby. When, however, it is desired to arrest the operation of the thread-guide, which is connected to the lever 27 as later described, the extension 37 lis slid upwardly on its pivot-arm 3G to raise the roll 47 out of the slot 48 and the crosshead 2O will then slide'beneath the roll 47 without imparting movement to the traverselcver. The manner and means for coupling and uncoupling the lever from the crosshead will be later described rin detail in connection with the stopping-mechanism of the machine. l

Mounted on the bed 2 at intervals along its length are a plurality of upright standards or brackets 50 which serve as supports for the fixed winding-spindles ot' the inachine. The brackets 50 are arranged in pairs, one on either side of each cani-casingY 6, and are provided with legs 51, 52 straddling the central cam-shaft l1, seeFig. 3, with their feet bolted to the side-flanges 8 of the bed 2. Adjacent the top of each bracket 50 is a bearing 53 in which is fixedly secured the dead-spindle or shaft 54 which carries the rotatable winding-mandrel or cone-holder 55. All of the several brackets 50 are of the same construction and therefore only one is shown in the drawings, but it is to bernoted that they are arranged along the bed 2 in right and left! posi-tions in relation thereto, so that the spindles 54 project alternately on opposite sides of the machine. Through this system of arranging the spindles the several units or heads of the niachine are grouped in more compact formation to economize floor space, while allowing the winding-inechanisms to be operated from both sides of the machine.Y

abutting the end of the bearing-53, see Fig'. 3.1The series of pulleys 56 on the several vspindles 54 are arranged in ahnement along troni; anv endless belt, not here shown, pass- Rotatably mounted on each windingspindle 54 is a belt-pulley 56 having its hub.

thelength ofthe machine and are driven y ing over them and held in contact therewith by suitable idler-pulleys. rlhe belt is driven from main driving-pulley at the end of the machine, which, in turn, is connected Tith the cam-shaft ll through the means of gears, belts or the equiialentv llsually a gainei or speed-changmg mechanism is employed in connection with the drivingclements to provide for adj stment between the speed of the pulleys which drive the copholders and the speed of the shaft ll which operates the several traverse-mechanisms. These driving and change-speed connections are not l erein shown or described in detail, however, as they may be of any well known arrangement as usually applied to machines of the present type.

The driving-pulleys 56 are connected to rotate the cop-holders or winding-mandrels 55 as next described: is illustrated in n igs, l and 8 the cop-holder 55 is constructed in l form of a tapered mandrel adapted to lit he interior of the conical paper-tube or l siell on which the cone-package is to be ufound. ln some cases, however, where machine is to be employed for winding lindrical packages, or cheeses, as they are sometimes termed, the cone mandrel is removed and a cylindrical tube-holder substituted. ln either case the driving-connections are the same, and consist essentially of a clutch-member 57 rotatable with the cop-holder and slidable on the spindle 5l to adapt its tapered face 58 to engage the correspondingly. formed clutch-face 59 of the pulley The clutch-member 57 also performs a further function, that of operating the expanding dogs or grippers which secure the cop-tube on the holder .55, but as this portion of the mechanism is shown and described in my companion application for patent, Serial No. 109,878, filed July 18, 1916, it will not be herein explained. Suffice it to state, for the present, that the clutch 57 is operated by a spring, not here shown, toY

normally maintain it in engagement with the pulley 56 and is adapted to be disengaged therefrom by means of a lever 60. The method of operation of the lever 60 Till be explained in connection with the automatic stopping-mechanism of the machine to be later described.

rEhe traversing thread-guide 6l, which is reciprocated longitudinally of the windingmandrel or cone-holder to lay the coils of yarn thereon, is mounted to slide on a traverse-frame 62 shown in Figs. l and 2. Referring first 'to Fig. 3, a lug 63 projects from the side of the standard or bracket 50 and in this is iixedly secured a vertical, threaded stud llounted on the stud 6e and held in place by a nut 65 is a hub 66, shown in Fig. 2, from which extends a horin zontal arm 67, see also l, Formed in the front face of the arm 67 isa semi-cir- Y leads to the notch.

cular groove 68 which serves as the track or guideway for the sliding thread-guide 61. The hub 66 may be turned about the axis of the stud 6l to adjust the track or arm 67 in relation to the winding-mandrel in accordance with the shape thereof. That to say, when a tapered mandrel 55 is employed, as shown in Figs, l and 2, the arm 67 is set at an angle to its axis so that the guide 6l will travel .parallel with the inclined surface of the mandrel. When a straight mandrel is used for winding tubes, or pan allel77 packages as they are sometimes called, the track or arm 67 is set parallel with the axis of the spindle 541-. ln either case the arm or track 67 is secured in its adjusted position by means of the set-screws 69 in the hub 66. Fig, et shows the arm 67 set parallel with the axis of the spindle 54, or at right-angles to the side of the machine and gives the best view of the construction and arrangement of the traverse-frame.

Referring to Fig. l, the traverse threadguide 6l is preferably constructed of sheetmetal, to render it light in weight, and is formed at its base with an oli'set portion or extended runner 70. The ruimer 7 G is bent to an arcuate form in cross-section, as shown in Fig. 4l, to adapt it to lit the semi-circular groove 68 in the-traverse-frame track or arm 67. A. cleat 7l, Figs. l and 4l, extending along the arm 67 and secured thereto by the screws 72 is formed at its top with a semicircular bead 73 fitted to the groove 68 in male-andfemale fashion. A relatively narrow space is left between the face of the bead 78 and the side of the groove 68, forining a slot 74 in which the shoe 70 of the guide 6l slides. @n the back of the runner of the guide 6l are two

fingers

75, 75 bent out to form a cup-like socket for the spherical head 76 of a rod 77. The opposite end of the rod 77 also carries a ball-like head 78 fitted to a socketed bearing 79 at the end of the traverse-lever arm del, whereby the guide 6l is connected to be reciprocated therefrom. rllhe upper portion of the guide 6l is of skeleton construction, as shown in Fig. l, comprising the converging sides or branches 80, 8O joined together at the top and having an offset blade 81, formed on its under side with a thread-notch 82. EX- tending across the thread-notch 82 is a wire linger 8lover which the yarn draws asv it The guide 6l sets in a substantially vertical position as shown in Fig. Ll, but is adapted to pivot in the guiding-slot 7l of the arm 67 to adapt its guiding-blade 81 to be brought into contact with the surface on which the yarn is laid. As the yarn builds up on its tube or holder the guide 61 swings outwardly away from the axis of the Winding-mandrel 55 with its position controlled by a pivoted traversefranie back 83. This latter element consists of a substantially flat plate or bearing-member 84supported by two

arms

85, 85, see Figs. 1 and 4, which are pivoted on a` rod 86 inV lugs 87 on the under side of the arm 67. A coiled spring 88 surrounds the rod 8G between the central lug 8,7 on the arm 67 and the inner bearing 89 of the back 83, tending to force the whole frame sidewise on the rod 85 in the direction indicated by the arrow Z), Fig. 1.v eOn the side of the plate 84 of the traverse-frame back 83 is a projection or lug 90 arranged with itsend, engaging the finished face of a curved arm or sector 91. The sector 91 is arranged concentric with the axis on which the traverse-frame back 83 swings and is ixedly supported with respect to the traverse-frame by an arm 92 reaching up from the track 67, see Fig. 2. Through this arrangement the pressure or' the spring 88 tending to slide the traverse-frame back 83 on its rod 86 maintains the lug 90 bearing against the sector 91 with sul'licient frictional resistance to prevent undue movement of the thread-guide 61 as the latter is iiorced away from the mandrel 55. That is to say,

the friction between the lug 90 and sector' 91 provides a clogging action to prevent the traverse-frame back 88 from forcing the guide 61 toward the axis ot the windinglspindle after it has once been carried away therefrom. As shown in Fig. 2, the travcree-trame back 83 carries a weightedarm 93 to counterbalance its weight and that of the parts carried thereby. rlhe weights 94 are applied to the arm 98 by slipping them onto a rod 95 projecting rearwardly from its side, and in this way any desired amount of pressure can be applied to the threadguide to resist its outward movement as the yarn-package builds up on the windingmandrel 55. The tension of the spring 88, however, is sutlicient to maintain the lug 90 on the traverse-trame back 83 bearing against the dog-sector 91 with enough :triction to resist the maximum amount of pressure applied to the frame.

It is well known by those skilled in the winding art that a yarn-package or cone can be built more compactly and uniformly if considerable pressure is applied to the guide at the beginning of the winding, but it is also a fact that the pressure must be reduced as the winding nears completion or the ends of thev package will become bulged and malformed. 1n view of this it is a common practice to provide the winding-guide with a differential pressure-device socalled, and in the present machine this is arranged as next described: Extending through bearings 96 atvthe top of the several brackets or uprights 50y see Figs. 1- and 2, are two

parallel rods

97, 97 which reach the whole v`length ofthe machine and serve as a means y-or supporting brackets for the idler-pul- Von a detent-lever 116.

leys and various other attachments to the winding-mechanism proper. A pair of

such brackets

98, 98 are clamped to the rods 97 by the bolt 99, seeFig. 1, and at one side thereof is a bearing for a pin 100. Pivoted on the pin 100 is an arm 101 carrying a rod 102 at its end on which are mounted a plurality of weights 103 held in place by a collar 104. Pivotally connected to the rearward end of the rod 102 is a link 105, see Fig. 1, having its lower end hinged 0n a pin 106 projecting from the side of the swinging traverse-frame back 83. As shown in Fig. 2, the link 105 sets at an angle to the weight-arm 101'when the thread-guide G1 is in a position adjacent or close to the winding-mandrel 55, but as the guide swings outwardly the link will be carried toward the vertical, thereby rocking the arm 101 to raise the weights 103. The inclination' of the link 105 varies with the movement of the guide as the latter recedes from` the winding-mandrel -during the growth in diameter of the package and in this way the link acts as a sort ot toggle connection between 'the traverse-frame and the pressureweights 103. Through this means the effeet of the weights 103 on the frame is gradually reduced from start to finish of the winding until eventually when the link 105 stands in a vertical position, their pressure on the frame will be practically m'l.

The automatic stopping-mechanism of the machine is illustrated particularly in Figs. S, 4 and 5 and will be next described: Referring first to Fig. 3, the clutch-lever 60, previously mentioned, is pivoted on a pin 107 held in an extension 108 of the upright or bracket 50. A second pin 109 supported on the bracket 50 at right-angles to the pin 107 serves as a pivot tor a lever 110, the hub of which is shown by dotted lines in Fig. 3. The lever 60 has a horn-shaped arm 111 reaching out to the right from its hub with its end adapted to rest on a projection or lug 112 on the hub oit the lever 110. ReferringV now to Fig. 4, the main arm 113 of the lever 110 is ott'set at its lower end and formed with a square shoulder 114 adapted to engage with a corresponding shoulder 115 The detent-lever 116 isof bifurcated form having two

legs

117, 117 pivoted on a pin 118, see Fig. 3, held in the bracket 50, below and parallel with the pin 109. A relatively light, coiled spring 119 is stretched between the detent-lever 116 'the' arm-113 of the ,lever 110. AThe spring` and the curved arm 111 of the lever A6,0,

120 acts to rock the lever 110 in the direction indicated by the arrow c, Fig. 4, when the detent-

shoulders

114, 115 Vare released, thereby causing its lug 112 to raise the arm 111 of the lever 60. This action causes the upright arm of the lever 60 to be rocked to the left, as viewed in Fig. 3, and as its end engages the side of a flange 122 on the clutch 57 the latter will be slid on the spindle 54 to disengage it from the driving-pulley 56. The lever 60 is controlled manually in starting the machine by means of a hand-lever 123 supported on the same pivot-pin 107. T he lever 123 is formed with a curved handle 124 and two

opposite arms

125, 126 adapted to engage the sides of the lever 60 with a slight clearance therebetween, see Fig. 3. The hand-lever 123 is also provided with a curved arm 127 adapted to engage the outer end of the arm 113 of the lever 110 to rock the latter downward to engage means for lifting the traverse-lever exten-- sion 37g to raise its roll 47`0ut of the slot 48 in the traverse-slide or crosshead 20. Re-v ferring to Fig. 5 the lever-extension arm 44 is pierced with an opening 130 at its top and the portion of metal cut away is bent at right-angles to form a projecting finger 131. The finger 131 is preferably rounded on its under side to adapt it to slide across the crowned top of the bridge-piece 128 and to set in the depression or slot 129 at its center.

Referring again to Figs. 3 and 4, the legs 117 of the detent-lever 116 reach forward in the

extensions

132, 132 and extending between their ends is a cross-pin 133. Pivotally mounted on the pin 133 is a vertical plate 134, widened at its bottom and formed with two prongs 135, 135, see Fig. 3. The prongs 135 are adapted to engage with the lfiuted periphery of a toothed-wheel or ratchet 136 mounted fast on the cam-shaft 11 and rotated continuously therewith. Normally the plate 134 hangs pendulous at one side or" the wheel 136 with its prongs 135 clear therefrom, see Fig. 4. By rocking the plate 134 into engagement with the wheel the teeth on the latter will act on the prongs 135 to raise the plate bodily, thereby rocking the detent-lever 116 to free its shoulder 115 from the shoulder 114 on the lever 110. r1`he plate 134 is operated to release the detents by means of an end-stop-lever 138, preferably constructed of wire to render it light in weight and sensitive in operation. As shown in Figs. 3 and 4 the wire of the lever 138 is coiled at 139 and 140 to encircle the ends of a pin 141 which serves as its pivot. The pin 141 is driven through lugs 142 eX- tending trom a bracket or arm 143 which is ixedly mounted on the pivot-pin 118 of the lever 116 and reaches down to one side of the plate 134. One arm 144 of the lever 138 reaches up and across the front ot the plate 134 and the other 145 extends horizontally outward to coperate with the tension-device which regulates the delivery or" the yarn to the thread-guide 61.

Any suitable arrangement of tensionmeans may be employed in connection with the winding-mechanism and 1 have illustrated a preferred form in Fig. 4. As here shown thetension-inembers are mounted on arertical arm or bracket 150 supported at any convenient position on the frame or bed 2. Projecting horizontally from the top of the arm 150 is a lug 151 carrying a pin or screw 152 on which is pivoted one of the tension-members 153. r1`his latter consists oi' a flat plate or strip of sheet-metal bent in a curve slightly eccentric to its pivot and providing a rounded face 154 across which the thread or yarn g/ draws. The pressure of the yarn maintains the tension-member or plate 153 normally in the position shown in Fig. 4 with its end 155 bearing against a fixed horn 156 on the top of the arm 150. A tail-piece 157 on the member 153 reaches up at the rear of the pivot 152 and is adapted to strike against the under side of the arm 145 of the end-stop-lever 138. Below the tension-member 153 is a second, fixed inember 158 comprising a curved plate 159 secured to a lug 160 on the arm 150. At the bottom of the arm 150 is a third lug 161 to which is pivoted a swinging lever 162. The lever162 carries a projection 163 having a concaved, curved face over which the yarn g/ drawn as it leads across the members 153 and 159. At the lower end or1 the lever 162 is a pigtail 164 through which the yarn leads to direct it to the tension-member 159. rlhe position of the lever 162 may be adjusted by suitable means, not here shown, to displace its projection 163 with respectto the other tension-members 153 and 158, whereby a greater or less bend is made the yarn drawing through the tension-device, and through this arrangement the amount of tension applied to the yarn is regulated in the usual manner. r1`he method of operation o1l the complete machine isas follows:

To prepare'the machine for winding the cone or package, a paper cop-tube or shell is iirst placed on the mandrel or holder 55 and secured thereto infany suitable manner as generally employed. rlhe thread or yarn y, see Fig. 4, is then drawn up from its source of supply, usually placed below the machine,

but not here shown, and then carried through the tension-device on the arm 150. The yarn leads through the pigtail 164, up

83, thence over the wire-guide 81a on the guide 61, and through the notch 82 in the blade 81.V The end ofthe yarn isthen se cured to the tube on the mandrel by winding it therearound, or in any other suit-able manner and the machine is ready to operate to wind the package.

Vith the machine at rest the lever bears against the flange 122 on the clutch-member 57 to hold the latter free from engagement with the driving-pulley 56 so that the mandrel 55 willbe held from rotation. At the same time, the bridge-piece 128 on the lever' 110 holds the traverse-lever extension 37 raised with itsroll 47 clear of the slot 48 in the traverse-slide 20, as shown in Fig. 5, so that the latter' reciprocates without imparting motion to the lever and its connected thread-guide 61. To start the operation of the winding-mandrel and thread-guide the handle 124 is raised to carry the arm 125 against the lever 60, thereby rocking the latter to the right Vas viewed in Fig. 3. rPhe upright arm of the lever" 60A is thus carried away from the side of the flange 122 on the clutch 57 to allow the latter to engage with the driving-pulley 56. The pulley 56 is driven continuously, as before explained, and through its engagement with the clutch 57 rotates the connected winding-mandrel or cop-holder 55 in the direction indicated by the arrow d, Fig. 4. The yarn y is thus drawn up through the tension-device while the thread-guide 61 is traversed along the cone-holder 55 as next explained-to deposit the coils of winding thereon.

detent-shoulder 114- with the shoulder 115 on the detent-lever 4116, the latter being allowed to tilt slightly by the stretching of its spring 119'. As the arm 113 swings downwardly to lock the detente the crossbar'or bridge 128 at'its end drops to allow the traverse-lever extension 37 to be telescoped on its arm 36 under the action of its spring 41, see Fig. 5. The roll 47 on'the extension 37 thereby drops down into contact with the upper edge of the traverseslide 2O which rides beneath it. As before stated, the slide 20 is reciprocated continuously from the cam 12 engaging its rollers 25, and as the slot 48 comes into alinement with the roll 47 on the lever-.arm 44, the

spring 41 will draw the extension 37 down to seat the roll in the slot as Villustrated in Fig. 1. This coupling kof the traverse-lever with the slide 20 takes place at the first stroke of the latter after the release of the extension 37, or practically atthe instant of starting the winding-mandrel. r.Phe traverse-lever 37-36 is then oscillated byand with the slide 20 to rock it on its pivot 32. As the traverse-lever rocks back and forth across the axis of the cam 12, it acts through` track 67 is made by releasing the nut 65 and turning the hub or bearing 66 on the stud 64, the set-screws 69 being employed to lock the arm 67 inrposition as before explained. For winding cylindrical packages the arm 67 is set parallel withv the axis of the winding-spindle 54, see Fig. 4, and the conical mandrel 55 is displaeed'by a cylindrical tube-holder, not herein shown.

As the yarn builds up on the winding- I vmandrel andthe package-increases in diameter,as indicated bytie dash-lines in Fig. 4, the thread-guide 61 is forced outwardly away from the axis of the cop against the pressure 'exerted upon it by thev weighted traverse-frame back '83. Meanwhile spring 88, seeV Fig. 1, acts on the traverseframe back to cause its lug 90 to bear against the dog-sector 91, thereby creating a slight friction therebetween so that the plate 84 is steadied in its movement and prevented from vibrating or jumping under the influence-of inequalities inthe winding. It will be understood, of course, that the traverse-lever 37-36 .oscillates in a fixed plane, but the guide 61 is allowed to swing back and forth relatively to this plane, or to travelin a path inclined thereto, in the case of cone winding, due to the universal or ball-and-socket connections of the p link 77 with the guide and lever. j As the guide recedes from the winding-mandrel with the growthk of the package' the traverse-frame back 83 acts through the link 105, see Fig. 2,`tol raise the weighted lever 101, and

through the toggle-action of the link he stopping-mechanism ofk the machine is' asi the i follows: When the yarn g/ breaks, or its supply becomes exhausted, the release of its pressure against the pivot-ed tensionineinber 153, see Fig. 4, will allow the latter to drop down through the action of gravity. ln this case its tail-piece 157 will strike against the under side of the arm 145 of the end-stop-lever 138, causing its extension lill to swing the hanging plate 13e into position above the ratchet 136, see Fie. 3.

'The teeth on the ratchet- 136 will then act on the prongs 135 to raise the plate bodily to tilt the detent-lever 116 upwardly. rEllis action unlocks the detent-shoulders lll, 115 to free the lever 110 which is caused to tilt upwardly under the'action of its spring` 120, see Figs. 3 and a. As the lever 110 is rocked by its spring 120 its lug 112 lifts the arm 111 of the lever 60 causing the upright arm of the latter to swing to the left, as viewed in Fig. 3. This causes the clutch 57 to be withdrawn from the driving-pulley 56 andthe winding-mandrel 55 will theretore cease to be rotated thereby. As the arin 113 of the lever 110 swings upwardly its bridge-piece 128 is raised to bring it into the path of the finger 131 en the traverselever extension 37. The linger 131 will therefore be caused to ride up over the arched incline of the 'bridge 128 during the next reciprocation of the traverse-lever in either direction until it finally seats in the depression 129. The roll i7 on the extension 37 is thus drawn up out of the slot i18 in the traverse-slide 20, as shown in Fig. 5, and the latter will reciprocate without impartingmovenient to the lever as before explained. rlhe traverse-lever 2'? is thus held inoperative to arrest the traverse ot the thread-guide 61 and the engagement ot the linger 131 with the-notch 139 acts as a detent to prevent accidental or unwarranted movement of the lever which might cause it to be rengaged with the slide 20.

lt will he observed that my improvements result in simplifying the construction of the mechanism or the machine and reducing the number and w ight of the parts, whereliy they are better adapted for high speed operation, inost of the operating elements `being constructed of sheet-netal provide tor the minimum of weight without crilieing he necessary strength and sti'ness, while at the saine time securing economy in their cost o manufacture. The several units of the machine are so grouped along the lied or traine as to eco-nomine space, whereby a greater number of spindles may be placed in. a given area than has heretofore been' stopping oi each guide is controlled individually and independently in accordance with the preiirred practice. Only a. single gamer-mechanism is required i'or all of the heads, and therefore the driving-connections considerably sinipliiied and improved. lt is also to he notedv that the several headare independently l L'al/cle for win either conical or cyli al iL only adjustment of the inechanir. No new parts are recuired for sucliadj 1. i nient except regards the cop-holder or winding-mandrel and this can be easily and quickly changed nf'ithout substituting a dii'llerent style of traverse-niechanisni. The machine also capable oi' being operated with less power than usually required where separate traverse-motions are employed for each spindle, in other respects the going parts are inuch lighter and easier running. A particular lea= e of improvement to be observed is t 1c reduction in the number et spindle and ,ininhalt-hearings required and the elininatioe of other wearing parts.
