This invention relates to winding machines and has for some of its principal objects to provide a winding machine wherein a new core is automatically substituted for a completed package and wherein winding is automatically begun upon the] replenished core without the necessity for any prewindlng of such core or any uniting or tying of one strand to another; a further object is to provide an automatic machine in which these operations are performed on a series of traveling winding carrier units which progress in a procession around the machine.

Other principal objects of the invention are to provide a winding machine in which the winding packages travel in a predetermined path in relation to the machine, usually in a procession, and

wherein the winding strandsa're wound on the the supply strandin position to be engaged by a new core;

. The machine illustrated herewith exemplifies' an improved mode of textile strand manipulation characterized by causing a winding strand package to travel in a predetermined path in relation to the machine while winding a strand on the package in overlapped layers which advance axially of the package.

Typically this operationv is performed simultaneously in respect. to Ya large number of wind-- ing packages; a procession is thus formed of packages in all stages of development from a freshly fed bare corel to a completely wound package ready for dofling. As illustrative of the winding performed on any one of the traveling .i packages, the winding strand may be caused to traverse a portion of the package to 'form a layer of short length, whereupon the range of traverse is automatically shifted axially of the package and another like layer wound. The illustrated machine of the present invention provides for the automatic supply ofempty cores to traveling core-holders at a predetermined part of their path about the machine, provides for automatically associating supplystrands with the serially replenished core holders. provides for automatically Fig. 'la is a horizontal section similar to but on.

strating winding of the strands upon their respective traveling cores to form packages thereon, and preferably provides for causing (during the travel of the winding packages) relative traverse between winding packages and'winding strands competent to effect the above described modeof winding on each package. Upon completion of `Winding of any of the traveling'packages the ma-v chine is capable of automatically stopping further windingr thereon; capable of depositing the wound package at a designated delivery point; and capable of severing the wound package from its supply.

Preferred form of guideway and winding unit conveying devices.

Referring to Figs. 1 and 2, a suitable guideway for the various winding units of the machine may comprise upper and lower rails II and I2, each disposed in opposite straight and semi-circular runs, (Fig. 2) and supported by transverse frame sections I3, and longitudinal end frame sections I4 and I5, (Fig. 1).

Suitable means for conveying the several winding units of the machine along the rails I I and I2 may comprise an endless chain I4' (Figs. 1 and 2) running on opposite sprocket wheels I5 and I6. Either ofthese sprocket wheels vmay be driven by any suitable connections, such for example, as those shown in my PatentNo. 1,609,639 as illus-v trated herein the sprocket wheel I5 is driven rocation in a sleeve il fast to the head portionV by an electric motor 2l), which is connected thereto by means of a belt 2l, pulley 22, (Fig. 2) a set of reduction gearing indicated at 23, and a pinion 24 meshing with internal gear teeth 25 'on the sprocket wheel, as more fully explained in my copending application, Serial No. 542,011,

` filed June 4, 1931. -A suitable switch 21, having buttons 2B and 29 for starting and stopping respectively, is adapted to control the motor 2U and Vhence the progress of thewinding units about the machine.

Preferably the several traveling Winding units derive their power for winding from individual motors traveling therewith abouty the machine. With this in view, the upper rail Il of the machine frame preferably carries electric conductor rails 3l, 32, 33, herein shown as three in number, suitably insulated from the frame and adapted to supply current to the traveling units, as described in my copending application, Serial No. 508,868led January 15, 1931, Patent No.

Preferred `general organization of a traveling winding unit An individual traveling winding unit preferably includes, like-the machines of my above patducted thereto through brushes ISI, |32 and IIS (Figs. 4 and 5) carried by a rotatable shaft |35 on the carrier and adapted to press against the stationary lconductor rails` 3|, 32 and 33. From the brushes I3I, I32 and |33, suitable wires, not shown, extend to the motor. The motor 52 is arranged to rotate the winding package, a preferred driving connection to such package consisting of a hollow center 55 (Figs. 5, 8 and 13) fast ori-the motor shaft and shaped to receive one end of a winding package core. Such core may be for example the typical filling or weftbobbin Y indicated at 51 in Fig. 4.

The other or outer end of the core is prefer- Vably held in a revolving hollow center mounted in ball bearings retained in. a housing Ii I Means is preferably provided for moving the outer hollow center SII toward and from the inner center 55 to grasp and to. release the cores successively handled by the unit. As shown in Fig. 4 the housing 6I for the outer center 60 is -fastened by a bracket 62 to a rod 63 which is mounted for recipof the carrier unit. YA spring 61 acting on 4a pin 63 which projects down from the rod 53 through a slot (not shown) in sleeve 64 urges the rod 63 and outer housingto the left in Fig. 4, thus gripping the core 51 for winding. The inner' end B3* of rod B3 preferably projects from the left of sleeve BI in position to be engaged by actuating means (explained hereinafter) for controlling the position of rod 63 and centerk B0 so as to grasp and release the cores at predetermined positions of the carrier unit in its path.4 A

The traverse mechanism, such as will now be described, is preferably arranged to perform its strand distributing operation without imparting any substantial twist to the strand. Preferably this traverse mechanism derives its power fromA a pinion 1li on the motor shaft, said pinion meshing with an internal gear 1I on the end face of a traversecam 12. The casing of motor 52 may be extended, as shown, to enclosethe cam'12. To

provide a rapid traverse w1th a cam of small size,

crossing at 13B.

its left end a cam follower BD adapted to run in the groove 13 of the traverse cam; operation of these elements imparts to the traverse assembly 11 a reciprocating movement along the axis of the rotating core s1 within a ent and copending applications, a main frame member 4D (Fig. 4) adapted to bridge the distance between upper and lower guide rails il and I2, confined to the lower rail by a pin 4I and roll 42, and carrying at its top a head member 43.

Upon this, head member 43 are preferably'provided horizontally disposed spaced outer rolls l5 and 4S (Fig. 3) and an inner roll l1(Fig, 4) adapted respectively to run on opposite faces of the upper rail II, and the whole unit is movably supported on this rail by means of spaced vertlcally disposed rolls 48 and 49 (Fig. 3) running onA the top edge of the rail.

VAn electric motor 52' is preferably mounted upon two spaced horizontal inward extensions 53 and 54 (Fig. :il of the head member I3. VCun- 4rent for operating the motor 52 is preferably conrange equal to the throw v winding package.

of the cam 12. In'the form of the device illustrated herein, the traverse assembly moves from one end of its relatively rapid reciprocating stroketo the other during the time required for twenty revolutions ofthe core 51.

Means is preferably provided for automatically shifting the range of movement' of the. traverse assembly to make the wound package consist of overlapped axially advancing layers, such means preferably acting in response to growth of the A preferred form of such means will now be described by reference to the construction o f the illustrated traverse assembly 11. Referring to Figs. 7, '7l and 8, thetraverse assembly 11 shown therein includes a central rotatable tubular part 9| having internal threads the form of reverse spirals A rod 16, carrying a traverse asl sembly 11 and mounted to slide in guides 1B and V19, has mounted at reciprocating rod 16. These two non-rotatable elements are fastened together by upper and loweriber 9| to turn a small amount on the threaded rod 16, thus advancing the whole traverse assembly slightly. This manner of advance of the traverse assembly is-repeated each time sucient strand is wound on a given layer. A wound bobbin is thus built with a very uniform diameter; the build or advance of range of the traverse guide is automatically regulated by the growth of the package regardless of the count of yarn and speed of winding.

The traverse 'yarn guide is herein shown as comprising a'l porcelain knob |05, which is dis'- posed over the winding core 51 in position to receive a supply strand Y from beneath the core,

conduct the strand above the core and to deliver it downwardlyI to the forming winding on the core.

The porcelain knob |05 is preferably held on the outer end of an arm |01 which is pivotally mounted at |08 on the upper yoke |00. An enlargement I I on arm |01 is normally acted on by a spring I I I to hold the arm and porcelain in the full line positions of Fig. 7. The porcelain guide |05 is capable of vertical movement such that it can ride upon the surface of the Winding package and is held there by its ownwelght and by the pull of the strand passing over it.

The supply of strand for winding on a core is preferably carried on the individual traveling carrier unit in the form of a wound package retained on a suitable peg, 'spindle or other holder |2| carried on a bracket |22 extending outward from the-lower part of the carrier frame member ,40 as shown in Fig. 4. From the supply, the

strand passes upward through a suitable tension device nato the traverse guide los.

Automatic stoppages of winding (a) Upon completion of full package.-The rotatable rod |35' which carries the brushes I 3|.

|32 and |33 is urged by a spring |35a (Fig. 3a) to .rotate in a counterclockwise direction (viewed in plan), so as to disengage the brushes from their respective rails 3|, 32 and 33, but is normally held against such movement by a reciprocable rod Il I' which engagesl a latch member `|40 at the top of the rod |35. (Figs. 3` and 4.) Reciprocable rod III carries, near its right or outer end, an adjustable abutment |442 positioned thereon so that may be engaged by the traverse assembly 11 when the latter nearly reaches the right end of its travel which occurs when the winding operation is substantially completed. Movement of the abutment |52 to the right by the traverse assembly 11 moves the rod III against the action of a spring |43, (Fig. 4) disengaging the rod III from latch member |40 and permitting rotatable rod |35 to removethe brushes I3I, |32 and |33 from the rails 3|, 32 and 33, thus stopping the motor 52. Thus during the travel of the carrier unit about the machine the winding operation is automatically stopped when the winding package attains a predetermined size. j

ner as in stopping winding ofa full wardly, V(to the right in Fig.

(b) VUpon breakage or exhaustion of the supply strand.-The reciprocable rod III, which acts to release rotatable rod |35 for stoppage of the motor, has pivoted thereon at I 50 (Fig. 4) a rod |5| of a length suiflcient to engage any one of a series of cams |53 (Figs. 1, 2 and 4) disposed at intervals along the 'upper guide rail II. As indicated in Fig. 2, each of these spaced cams |53 increases in width in the direction of travel of the carrier units; the effect of a cam |53 is to force outwardly the rod |5I of any of the carrier units engaged thereby, thus moving the reciprocable rod |4| tothe right, releasing a rotatable rod |35 and stopping the motor 52 in the same manpackage. The rod I5I is normally held clear of the cams |53 by a crank |58 (Figs. 3 and 4) forming part of a plvoted detector wire |59 which rests on the strand running from the tension device |23 to the traverse guide |05. Upon breakageor exhaustion of the strand, d'etector wire |59 drops to the dotted position in Fig. 4, allowing rod I5I to drop into position for its end to be engaged by the next adjacent cam |53, whereupon stoppage of the motor 52 occurs as just explained;

(c) At the end of a. predetermined winding interval.-As is more fully/,explained below, winding the individual unit to pass around the machine' and return again to the right-hand or replenishing end. By the provision of such means winding ceases at this point, even though the other stop devices described above have not as yet operated.

In the illustrated machine winding may be stopped at the end of a predetermined interval by an arrangement of the current conductors 3 I 32 and 33, such as shown in Fig. l, wherein these vconductors end near the right-hand end of the machine; upon reaching the end of these conducting rails, the motor 52 of thetraveling carrier unit is deenergized and remains inactive until the carrier unit again' reaches the start of these same rails at a point indicated at 3| a (Fig. 2) just before a starting cam 21| described below. If desired, the rails 3|, 32, 33, may merely be provided with deenergized sections extending around the right-hand end of the machine to this'point 3|*1L in a. manner similar to that disclosed in my couary 15, 1931.

.AtomaticV `holding and relcam'ng` of winding package core and collection of full packages It has been described above how', during its travel along the guide rails, each unit holds a winding package core 51 between a live center 55 and an outer dead center 60, which later is carried by bracket 62 on a. reciprocable rod 53.! Means is provided for automatically causing the vcarrier unit to release its core 51 at a predetermined point in its travel. As indicated in Figs. 1, 2 and 4, a xed vertical post |10, coaxial with the sprocket I6, may carry a cam I1I of such shape and position as to engage the inwardly extending end 53l of the reciprocable rod 53 of each carrier. Upon contacting with this cam I 1I, the reciprocable rod 63 oi' the carrier is forced out- 4) carrying the bracket 32 and outer center 60 with it. thus rebroken. Means is 2?492 most core of the stack thus held is in position leasing the winding package core 51, This opery ation will take place whenever the carrier unit passes slightly beyond the position of the single unit shown in Fig. 2.

It will be observed that upon release of the core 51 (usually carrying a full wound package) the strand extending from the supply |20 is still unpreferably provided'for detaining the released core and package on the traveling carrier during the time necessary to associate the strand with new core for resumption of winding. In the illustrated machine, such means is shown as comprising a package receiver in the form of a trough |14 disposed directly beneath the normal winding position of a core and preferably sloping downwardly towards its outer end in the form of a chute as shown in Fig. 4. Cooperating with these troughs or chutes |14 of the several carriers there is preferably provided an arcuate plate outer lower ends of the troughs until the carriers reach a point somewhat beyond the extreme semi-circular end of the machine. Upon'reaching the end of this guard plate |13, a full package or partially wound core in the. trough |14 of the carrier is free to slide out the end of the trough and into a receptacle |15 suitably positioned.`

Thus the machine provides for delivering all of the released wound packages. at a predetermined part of the travel of the several units.

Automatic supply of winding package core The means provided in the present machine for holding`and supplying fresh winding cores to the carrier units is s hown as comprising a magazine (Fig. l) which may conveniently be mounted in part at least upon a bracket |8I carried by a vertical support |82, the magazine be,

| (Figs. 1, 2 and 4) disposed to close the to be cleared both outer dead. center 60, when this outer center has been forced to its outermost position by the action of the cam |1|; furthermore, the lower# most core 51 of the magazine is held alt the ap-y propriate level to be engagedbetween these twor centers 55 and l00 o a s 200 until'the core 51 is withdrawn from these spring fingers; the spring fingers retain all the remaining cores in the magazine and the hinged lower portions of the magazine swing downward into position to supply a core to the next traveling positioned approximately in prolongation of the llongitudinal axis of the machine. The exact construction of the magazine will of course vary with the particular kind of winding core to be employed by 'the' machine; for the typ'e of core clined rods |84, |85, spaced at a suitable distance to hold the cores by theirlarger head ends with their smaller ends depending as indicated in Fig. 1. The cores slide 'down the two rods |84 and |85 until they are engaged by spaced arcuate plates |86 and |81 on both sides and their tip ends Yrest upon a curved portion |88 of the bracket I9I. The arcuate plates |00 and |||1J are fastened together by a U-shaped strap member |89 connected at its two ends to the bracket 18|. The'closed end of this U-shaped strap member |89 is connected at |90 to an arcuate plate |9| which in turn is carried by a bracket |92.

The lower portion of the magazine includes an arcuate plate |95 hinged at |95 to the plate |9|, and a U-shaped member |99 integral with the arcuate plate |95, (Figs. 9 and 10).. Fastened illustrated the magazine preferably utilizes in on bothsides of this swinging member |99 are downwardly extending spring iingers 202, 202, each approximately in prolongation ofthe platesl |05 just above them. The magazineY includes also another U-shaped member |99' pivotally mounted at' 200 on-the bracket |8| soas to swing about the same inclined axisas the U-shaped member |99. Spring fingers 203, 2'03l fastened on .member |99* extendugenerally in downward prolongation of the upper plates |01. The spring fingers 202, 202* and 203, 203n preferably have their lower ends slightly inturned `as shown in Fig. 10, yieldingly to hold the lowermost core of a stack in the magazine, as shown in Figs' l and 9 The position of the magazine is such that the lower- Y ing winding v unit.

.The pivotal mountings of the lower parts of the magazine are of advantage in allowing the relative motion of the core-holding centers 55 and with relation to. the magazine to Withdraw a core from the magazine. In addition, such pivotal mountings allow the spring lingers 202, 202., 203 and 203* to swing to permit the reciprocable rod 16 of the traveling unit. to Apass thereunder without interference. The parts |99 and |99 although mounted to swing on a common axis, preferably have freedom for independent motion about pivots and 200 because of the fact that the outer Itip end of a 'core moves on a greater radius than the inner end of the core at the` curved end of the machine; the pivoted sections of the magazine which retain the two ends of the cores.will therefore not move exactly together.

Automatic cessation 0f travel of the units upon exhaustion or stoppage of the magazine In case the' magazine |80 is empty, or in case a core 51 is not in place therein to be engagedA between the centers 55 and 60 of a traveling unit, the outer center 60 and reciprocable rod 63 of theunit will travel farther than usual to the left when the end 53,a of rod 63 is released by the end 205 of the cam |1l. Apush pin 2|| (Fig. 11) operating a piano wire 2f|2 ina exible conduit- V2|3 is disposedimmediately beyond the end 205 of the cam |1|. This push pin 2|| is normally cleared bythe end i3* of the rod 63 when movement of y.the rodA 53 has been checked by the engagement of acore 51,- Movement of the rod 5I to a greater distance to the left when the unit fails to engage acore forces this push pin 2|| and the piano wire '2|2 inward. end ofthe piano wire carries a pin 2|4 (Fig. 1) y disposed in position to strike and voperate the stopV button 29 of the vpush button switch 21. This mechanism thus detects the failure of the magazine to supply a fresh core to a traveling unit, and u'pon the detection of such failure de energizes the motor 20 and thereby stops the.

traveling motion of the various carrier units. In additionl to preventing idle movement of the machine m they absence of an available supply of freshcores this mechanism also serves to prevent any carrier unit from traveling Afar enough to by the live center 55 and the passing unit vwhen the'r outer dead center is forced inwardly toward-the u The opposite the carriers to continue discharging their wound packages after an exhaustion or stoppage of supply of fresh cores.

Automaticassociation of the supply strand with the fresh winding core The machine in its preferred forms is capable of automatically associating the supply strand which travels with the given carrier with the fresh-core without the necessity for any prewinding on the newly supplied tying of knots.

It will be observed that the location o f the porcelain guide eye ls such that when the bobbin is released from its centers and dropped into the trough |14, this porcelain eye |05 retains the run of yarn extending from the tension device |23 to the wound bobbin; it is preferably this portion of yarn extending from the porcelain guide eye |05 to the completed released bobbin which is associated with the newly supplied core; thus the traverse guide eye |05, tension device, and any other'instrumentalities acting on the strand need not be rethreaded. Means is therefore provided forcarrying the portion of yarn which rtends from the guide eye |05 to the released bobbin over to the left in 6 to a position wherein this strand can be associated with a new core inserted between thecenters 55 and 60. l

Preferably the hollow center 55 which engages the head of the core is provided with means for Iimparting a winding rotation` to such a strand presented thereto so that this portion of the strand, placed in engagement with the hollow center 55, will be caused to wind up upon a core newly placed in the center 55. As shown in Figs.

5 and8, the, oenter 55 is preferably provided around its rim with toothed serrations 220 forming notches across which the yarn Y may be laid as shown in Fig. 8. A strand thus laid across the serrations in the hollow center 55 will be so positioned as automatically to be gripped between the center-55 and'a new core 51 when the core '51 is forced endwise against the center 55l rby the outer 'center 60. In this way the strand leading from the supply can be automatically associated with the new core.

It will be understood that traverse assembly 11 of the unit progresses relatively slowly toward v the right during winding and at the completion of winding attains approximately the position shown in Fig. 5. The illustrated machine includes mechanism for automatically restoring this traverse assembly by a rapid return movement to a predetermined position at the opposite end of its travel, and the mechanism employed for this purpose preferably also serves automatically to carry the strand extending from the porcecore or for any lain guide |05 over into engagement with the .7

serrations 220 of the hollow center 55. As previnusly described the traverse assembly includes an arm |01 pivoted at |08 and normally held in the full line position of Fig. 7 by a spring This arm |01, which serves to hold the porcelain guide |05. preferably includes an unturned portion 230 (Figs. 5. 6 and 1) adapted to cooperate with a stop cam 23| (Figs. 1 and 2) for moving the traverseassembly tothe left. This cam 23| which may conveniently be carried by arms 233 and 234 extending from the `vertical post |10 is so positioned as to engage the upstanding extension 230 on the arm |01 soon after the full package has been released by the center 50. Further movement of the carrier around the end of the machine turns the arm |01 to itsdotted position .in Fig. 7 and moves the entire traverse assemline position of Fig. 7, the portion |0'|EL of this arm striking the rim H5* forces the wheel ||5 to the right in Fig. 7`transversely of the rod 16, and disengages the threads 92 op the tubular part 9| from thecorresponding threads 93 on the rod 16. The traverse assembly is thus free to slide along the rod 16 under the influence of the cam 23|. Upon arrival at the left-hand end of the rod 1i the arm |01 and its attachments still occupy the relative position shown in dotted lines in Fig. 7; in this-way, the porcelain eye |05 and the upturned extension 230 are moved past the serrated hollow center and clear the magazine and its retained bobbins.

I'his movement c1 the traverse assembly to the left is preferably utilizedl to associate the strand Y extending down from the porcelain eye |05 with the serrated hollow center 55. For this purpose the traverse assembly preferably carries a wire 240 having a horizontally disposed arcuate portion 24| (Fig. 8) below the level of the hollow center 55, and a vertical portion 242 pivotally mounted to turn about a vertical axis in a loop 243 carried by the traverse assembly. At its upper end the wire 240 is provided with a crank arm 244 which is slidably engaged in a;l slot 245 in the arm |01. The relations of these parts are such that when the porcelain eye |05 occupies its full line position in Fig. 7, the wire 240 is clear of the path through which a full package drops in being released by the centers 55 and 60. When the arm |01 is swung to its dotted line position in Fig. 'I by the action of the cam 23|, the wire 240 swings through an arc of .about as shown by the dotted positioncf this arm (Fig. 7). During this movement the hook-shaped outer portion 24| of the wire engages the strand which now extends downward from the porcelain eye |05 to the released package. Movement of the traverse assembly to the left along the rod 16 (Fig. 4) causes the arm 240 to carry the yarn Y to the left; the porcelain eye |05 and the wire 240 engaging the yarn above and below the serrated hollow center 55 respectively, place the yarn across this center as shown -inFig 8.

Automatic severing of the supply strand from the wound package Automatic means for cutting off the yarn of the wound package from the portion of the ysupply strand now clamped is herein shown as comprising upper and lower scissor blades 250 and 25| their full line positions 55 on the rod 15.

. yarn or the completion of (Figs. 2, and 12) suitably moun .for example upon an extension |1I of the cam- ITI, in position to -engage between them a portion of the strand extending down from the wire 245 to the released full package when the wire 245 is at its extreme inner or left-hand position. Upper blade l V255 is preferably pivoted to the lower blade 25| at 252 and carries integral therewith an'inward-ly extending crank arm 253. The head portion of the carrier is provided with a depending pin 25| disposed in position to engage this arm 255 in passing and to turn the upper blade 252 so as to sever the yarn. A suitable spring 255 then returns the scissors to their open position ready to operate upon the yarn of the next traveling carrier unit.

Rsetting of traverse mechanism in position to xi wind After clamping the strand between the new core and the hollow center 55 and severing the completed package from .this strand, the traverse guide |55 is automatically carried over to the yarn receiving portion of the core in position for winding to commence.- For this erably provided a cam 260 mounted integral with one of the supports 254 of the cam 23| ,--this cam 255 projecting into the path traversed by the upper projection 255 of the traverse assembly. Upon contacting with this cam 255, the projection 25|), the arm |51 and porcelain guide eye |05 are returned to positions such as are shown in full lines in Fig. '1. The cam Z55-is so positioned with respect to the position of a new core 51 as to leave the porcelain eye |55 at approximately the head end of the core in position to start a layer of winding at this` end. Meanwhile the end of the yarn Y which extends over the porcelain eye |55 remains ancliored between the end of the core 51 and the hollow Vcenter 55 so that when the hollow center 55 begins to turn the yarn is drawn on to the rotating core.

When the arm |51 and eye |||5 are returned to in Fig. '1 in position to start winding, a projection |51 on arm |01 coni tacts with an inner surface of the rim |'l on the wheel ||5 and urges the associated threaded lbarrel 5| into engagement with the half-threads The traverse assembly is thus fastened to the rod,15 so as to be moved therewith as the rod 15 reciprocates under the influence oi the cam 12in winding.

Resetti'ng of stop motionl mechanism and resumption o! winding When the carrier encounters the live conductor rails 5|, 52 and 55 on the opposite side of the machine from that shown in Fig. 1, a. resetting mechanism acts tor restore brushes |5I, |52, |55 into position such as shown in Fig. 4, in contact with these rails. It will be understood that in the case of most oi' the carrier units, the rod |55 will previously 'have been rotated (either as a ,consequence of breakage or exhaustion of the a full package) so as to remove the brushes from contact with their rails. To restore the brushes into contact with the rails ythe crank arm 215 is provided, on the lower end is rotated thereby in a direction opposite to that This rotates the induced byA the spring iw.

.side of the machine shown extended around the curved end purpose there is pref- (Fig. 2i, conveniently lbehind the rod lli (when these parts are viewed as in Figs. 1i,y 5 and 6), now forces this rod |41 slightly to the right by a camming action and passes its end allowing this rod to snap back behind it, the latch member |45 now being in front of the tip end of rod Ill as shown in Figs. -i and 3*. I'he interengagement oi` rod Ill with latch member |55 thus locks the brushes |5|, |32 and. in their operative positions, in contact with rails 5|, 52 and 55.

By the time the crank arm 215 leaves the cam surface 21| the motor 52 will have started, thel strand will be winding upon the fresh c ore 51, and the portion of the strand engaged by the detector arm |55 will be under tension so that the brushes |5|, |52 and |55 will not again be disengaged until some condition oi breakage or exhaustion of the strand occurs or a full package is completed. The last stop-motion cam |55 on the in Fig. 1 is preferably to a point |55b just beyond the starting cam 21| in the form of a ledge |55* on top of which the stop-motion rod IH can ride. This rod |4| is thus supported during the time in which there is no winding tension on the supply strand.

Since the various operations incident to the automatic control of winding and to the automatic replenishment and initiation of winding have been described for one of the several traveling carrier units, no iurther description of the operation of the machine as a whole is deemed necessary; it will be understood that the various controlling' and replenishing operations are performed with relation to each of the several carrier units, the carrier units being subjected in egular order to the several replenishing operaions.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents -which fall withinthe scope of the appended claims.
