a form vofpackage P is shown in Figs 4 of the present drawings as being twoundlon a cylin- .dric'alcoreor tubett with a gradually increasing and diminishing length-oi traverse as illustrated graphically in Fig. 5. It is-to be understood,
however, that the-p'resent'machine is adaptedior adjustment to wind packages withT the; traverse or; the yarn varying in extent in different order from that referred to" above and withtheflarn wound on cores or tubes of different shape',-such for example, as com r holders.
Referring to Fig. '1 of the present dra wings,
.thelirive rition is herein illustrated'as embodied a multiple :unit or 'gang-type'machine, two
winding heads or units {being mounted on beds .3 supportedfromlthe floor by legs 4; {Each bed .may'mount. a series oi units, and as'herein shown two gang machines v. are' arranged end-for-end ne at Q and coupled together for driving by a single motor indicated at M.
mounting in the form of a bell-crank lever 45 Each winding unit comprises a box-like frame 5 carrying bearings for a horizontal winding spindle 5 and a cam-shaft 1 arranged therebelow a in parallel relation thereto. The winding spindle 5 projects forwardly from its bearings in the frame 5 and carries thereon a suitable mandrel with by suitable clutches, not herein shown, as
usually provided in machines of the present type. The belt H passes around a pulley 13 on the motor-shaft Hand-thence leads under idlerpulleys l5 and I5 to direct it-'acress-tlsie topof the drive-pulleys l2 on th spindles .5. Preferably, a series of idler-pulleys I! are journaled on pivoted arms It to adapt them to bear against the belt;ll to maintain it in contact with the pulleys l2 on the several spindles 5. An idlerpulley I1 is provided adjacent each winding unit or head'2 and the belt H is continuous between the drive-pulleys i2 with its'slack length extending from end to end beneath the spindle drivepulleys l2.
Referring to Fig. 2, the cam-shaft I of each unit carries a helical cam fast thereon within-the frame creasing 5; the cam-shaft being driven from-.the winding spindle 5 by any suitable arrangement of'belt or gears as usuallyvemployed'in, machines of the present type but not herein illustrated. The cam 20 is formed with a helical groove engaged by a roller or bowl 22 on a reciprocable traverse-rod 23. The traversepivoted to the arm or slide 4l by means of a stud 45. The main arm of the bell-crank lever .45 is formed at its sides with bent-over ears or lugs 41 and 43 for engaging around the sides of a hairpin-shaped portion 43 of the thread-guide 40. As herein shown the thread-guide is constructed of wire bent into a relatively narrow loop 50 at its outer end, through which the yarn y' is adapted'to feed, the loop being a continuation of one arm of the hairpin-shaped loop 43 which supports the thread-guide on the bell-crank.
lever 45. The loop 53 of the thread-guide 40 is oil'set from one arm of the loop 43 by means of a sharp bend 5| and the end of the wire in the "loop 53 is bent at an angle "to overlie this arm of the loop 43. In this way a re-entrant opening is provided for drawing the yarn strand 1 along the inclined portion 52 and between the sides of the loop 50 of the thread-guide to insert it therein, the yarn being preventedfrom release therefrom by the right-angular bend 5| in the wire. The hairpin loop is held in connec tion with the lever by'means of an arcuately' offset portion 54 on one of its arms adaptedto snap into place between the two ears 4!. By this construction of mounting the thread-guide 45 is adapted to rock or oscillate with the lever 45.
' The outer end of the arm or slide 4| is bent downwardly and formed into a V-shaped catch or hook 43 engaging around the beveled edge of the traverse-frame back 32 and adapted to slide therealong. The thread-guide 40 is carried by a 75 of the cam-track 55 is formed with a curved arm 62 carrying a stud or pin 53 riveted theretoand projecting upwardly through va bearing aperture in a slide-bar 55 which extends thefull length of 45 the gang-machines and'is similarly connected to the cam-tracks of all the several winding units.
' in variable angular relation tothe plane of movement of the traverse-rod 23 and the thread-guide '43 carried thereby; two opposite extremes of position of the cam-track being represented in Figs.
6 and 7. By thuschanging the position of the cam-track the thread-guide 40 associated 55 therewith is caused to .be rocked or oscillated during each traverse by the sliding engagement 45 with-the supported in a bearing 53 on a casing o'r bracket 59. The shaft 51 carries a bevel gear 13 pinned to its rearward end which meshes with apinion H on a shaft 12. The shaft 12 is .i0urnaled in a bearing 13 on the bracket 33 and carries :a sprocket-wheel 14 fast at one end. The sprocketwheel 14 is connected-by a chain" to another sprocket "last on a shaft "extending horizon.- tally below the winding units and Journaled in suitable bearings 13 and 13 carried by brackets 88 and 8| supported from the legs 4 of the machine frame. I
The bracket an is formed with a bearing :2 in
which is journaled a shaft 83 carrying a beltpulley 84 at one end. The pulley 84 is connected .by an endless belt to a similar smaller pulley.
85 fast with and rotatable by the idler-pulley,
previously referred to as having the drivingbelt,
engages the periphery of the cam 5.6 to cause the bar to be reciprocated therefrom with a relatively slow longitudinal motion. The roller 98 is j-ournaled on a stud 9| projecting from a bifurcated member 92 which straddles the slide-bar 65 and is clamped thereto bymeans of a nut 89 and washer 93 shown in detail in Fig. 3; a wire ring 94 sprung intoa circumferential groove 95 at the end of the stud 9| .serving to hold the roller 98in place thereon. To' maintain the roller 98 constantly bearing against the rim of the cam 66 ahelical spring 96, see Fig. 1, acts to draw the bar 65 toward the'left; the spring being anchored .to a pin .91 fast in the frame 5 and. connected at its opposite end to a member 98 fixedly clamped on the slide-bar by means of a set-screw 99.
When .the machine is equipped for sizing or emulsifying the yarn as it is wound into the pack! age a moistening device may be provided; for example in the form substantially as shown in Fig. 1 of the present drawings. As herein illustrated the moistening device comprises a trough or tank I88 for the winding units of each gangmachine. The troughs I88 are arranged below the winding heads 2, being supported from the legs 4 of themachine frames and adapted to contain the desired emulsifying liquid such as a suitable size. A horizontal shaft IN is joumaled in,
bearings at the ends of each trough and carries a series of rolls I82 which dip into the liquid in thetank; a chain I83 connecting the roll-shaft to be driven from the lower shaft 11 previously .referred to, see Figs. 1 and 2, by means of sprockets I84 and I85. -The yarn y is supplied from a suitable source arranged below the emulsifying device, but not herein shown, and the strandleads up. through an opening in the front of the trough and is'directed across the surface yarn 1/ is wound on the core or tub'e't and' trav-f ersed back and forth longitudinally thereof by the reciprocation of the thread-guide 48 carried by the traverse-rod 23 The machine may be started to operate with the former-guide or camtrack 55 in any positionin which it has remained after a previous winding" operation and the'initial traverse'of the yarn" on the tube twill be regulated in accordance therewith as the thread; guide is oscillated from the bell-crank lever 45 due to the travel of the shoe 58 in the slot 5T of the cam-track. For example, if the cam track 55 has been rocked tothe position illustrated in Fig. 6 afterthe cam 55 has been turned to the position shown in Fig. 1, the thread-guide 48 will be actuated with a maximum extent ofithrow and the yarn will be traversed to substantially the thread-guide 48 the' full length of the tube t shownin 1 ig. 4..-. Each time the traverse-rod 23 iscarried outwardly to the full extent of its traverse 'thes'hoe.

On the other hand 'jas the traverse-rod 23 moves back in' 'the reverse direction the engagement of'theshoe 88 with the slot 51 in the cam-track 55 willrock the,lever"45 in the opposite direction to carry the' loo p 58Iof indicated by dash lines mm. 16 whereby to ex tend the traverse of the yarn in this direction.,, 2 Asthe winding continues the edge-camiifi" is rotated slowly throughits connections with the main drive of the machine,'that is by the rota tion of the shaft 11 communicated through the sprocket .18, chain'l5,'and sprocket I4 to th'e pinion II and gear" on the shaftlil 'of't'he' cam. This slow turning, motion of thec'am 86 causes its eccentric edge to act against the roller 98 fast on the slide-bar 55to slide the bar towardv the right as viewedin Fig l. The b'ar85being con nectedto the cam-track 55 at 53 causes the track to be slowly shifted or rocked on its pivot 56 until eventually it assumes the position shown in Fig. 7 of the drawings. During thispivotal movement of the track the inclination of its slot 51 with respect to the transverse-rod -23 will be gradually lessened sothat it'will havea diminishing effect to rock the bell-crank lever 45, thereby reducing the length of traverse 'imof the moistened roll I82 by means of a suitable guide I88. From the guide I88 thestrand y 7 7 feeds upwardly through the thread-guide 48 and .parted to the strand of yarn 1 being deposited on the tube it. As the cam-track 55 reaches a position parallel with the traverse-bar 23 theoscillating motion of the guide will cease entirely so thatfthe yarn will'be traversed to anextent 7 beyond this latter point until'eventuallythe of operation is explained as follows: Each head of the machine is prepared for winding by leading the strand of yarn y from its supply across the moistening roll I82 and through the fixed guide I86, whence it is carried up through the thread-guide 48 and its end attached to the core or tube t on the winding spindle 8, the tube hav-.-.
equalto that of the traverse-rod. The displacement of the cam-track. 55 continues, however,
track reaches the position shown 'in Fig. 7. As the track 55 is shifted from its parallel relation to the traverse-rod 23 towardthe inclined position shown in Fig. 7 its action on thelbell-cran'k lever 45'and thread-guide 48 will be the opposite from that first described, that is it will rock the thread-guide 48 inwardly i from the limits. of movement of the traverse-rod to shorten the traversev imparted to the strand 1 or,v in other words, it will gradually reduce the lengthof the layers being deposited on the package wound on the tube t, After the bar has reached the end of its movement toward the right, as indicated in Fig. 7 it is swung back in the opposite direcdies. As each spindle 8 isrotated the strand of rearwardly to the position out the winding of the-package.
The motion imparted to the: slide-bar SI by the cam ii is relatively slow so that the change in traverse of the yarn is gradual. However, the
. actuation of the slide-bar "is so timed that it will rock the cam-track I on itspivot throughout its full movement in opposite directions a said member to adapt .it to oscillate with respect thereto, and means 'to oscillate the thread-guide on the reciprocable member first in one direction andthen in the opposite direction during its re-' ciprocation thereby to alternately increase and. diminish the length of traverse of said threadguid'e at both ends of its stroke throughout the of a package on thewinding spindle. '3. In a winding machine, a= rotary winding spindle, a member reciprocable opposite said spindle, ,a thread-guidepivotally mounted on sufllcient number of times to provide a relatively large number of changes in the traverse of the in each package. For example, it has been yarn found that starting with the maximum extent of traverse and reducing its length gradually to the minimum, and then increasing the traverse to the maximum, this cycle if completed four times a minute when winding the yarn at a spindle sp'eedof-l2l0 R. P. M. will produce a satisfactory package of the type illustrated in Fig. 4 of thepresent drawings. The ratio between the maximumand minimum length of traverse and the period of change in successive cycles is arbitrary,
however, and maybe adjusted to wind packages of diflerent'type which, in most instances, will have the same general form, that iswith the peripherytapering toward the ends due to depositing more yarn at the center of the mass. m. 5 is a graphical representation of one preferred method ofhehange in the traverse of the 7 yarn from maximum to minimum extent and back to maximum extent continuously through successive cycles ofthe winding. After the package is completed to the required size it is removed from the machine and the winding may be continued to produce other packages without any adjustment of the mechanism of the; machine. That is to say, the winding of a pac fiagemay be started at any point as regards the length of traverse without materially affecting the form or structure of. the package produced on themachine. .It will be observed from'the foregoing specification that the present invention provides a. novel and ingenious winding mechanism for continuously changing the 'lengthof traverse of the yarn being wound to produce packages of improved typewherein the layers are of graduated length to secure the advantages hereinbefore set forth and stated more fully in my copending application referred to above.
, While the invention is herein shown and described as embodied in a preferred form of construction, it is to be understood that modiflca tions may be made in the structureand arrangement of the parts of the winding mechanism and the .means for controlling the change in the of traverse of the yarn during winding on .theBmachine without departing from the spirit or scope of the invention.,Therefore, without limiting myself in this respect, I claim: 7
