Application filed April 16, 1928. Serial No. 632,379.

ing, taken in connection withthe accomfull, clear, and exact panying drawings, is a description.

This invention relates to certain improvements in winding apparatus, and is here illustrated in its .adaptation to spinning jennies, altho it is applicable for use in con- 15, nection with roving frames,spinning frames,

twisting frames, formers, layers or twisters, in which the product, while being revolved around a common axis to give it its twist,

is presented to the coil, cop or-ball and wound thereon. v 1 a The apparatus illustrated is peculiarly adapted for winding twine, thread, yarn, rope, "or the like in cylindrical, conical or otherwise shaped coils, and in such a manner that'the ends of the coils will be self supporting and so that the distance between any two successive will be substantially the same regardless of the diameter of the coil or ball. In order to sired density and uniformity of winding, it has been customary in the use of spinning jennies and other apparatus to first wind the twine on bobbins with disks or heads at each endthereof to keep the loops of twine from coming off the end of the coil or ball and,

; subsequently the twine. was delivered from the bobbin to other winding mechanism for producing the desired coil or ball preferably of a character having self-supporting ends.

Certain of the advantages of this invention reside particularly in the elimination of the re-winding step and in the production of an a paratus by means of which the de sired winding can be effected d rectly .as the twine is delivered from the twisting or spinning equipment,'which desired winding may include the self-supporting character of the ends of the coils if that is desired.

Further, the invention avoids the necesw slty of using headed bobbins or spools and permits the j us'eQof a collapsible or other core of paper, wood or the like and the om ssion of the bobbin admits in many cases of the winding of larger or-more suitabl 5 shaped coils or balls, thus eliminating muc re-windin and dofiing.

Other 0 jects and advantages relate to the details of form, construction, arrangement and operation of the apparatus, all as will more fully appear from the following description, taken in connection with the accompanying drawings, in which Figure 1 is an elevation of a spinning jenny-combined with the winding device of this invention.

In order to specifically illustrate the construction and operation of this invention, it' has, as above suggested, been disclosed in connection with a type of spinning jenny so commonly used for spinning hemp or sisal fibre, but it will be understood that this invention is in no way limitedor restricted by l The operation of portions of paratus disclosed is that ordinarily used and well known in connection with spinning jennies. By means of the constant rotative movement of the capstans 3- driven by belt -4, pulley -5-, shaft -13- and -7-, and -8- the fibre -1 is drawn 'through the usual nipper 2-. At the same time by means of the constant rotative movement of the flyer, 9 driven by belt 10, pulley 11- and concentric shaft 20-, the fibre is twisted in the nipper -2-and appears at the point -i2- 1n twisted form.

the aps5 From the nipper 2 the twine passes through a conduit or passageway in the center of the shaft 13 and around the capstans 3- and over the sheaves -14 and'15 to the laying device -16 and on to the coil winding cylinder -17-. The operation of the structure so far described is well known. The coil winding cylinder 7 17 is axially supported by the removable shaft 18 and is connected'to the tubular shaft 19 for simultaneous rotation therewith in the usual manner as best illustrated in Figure 2, the shaft 18 being mounted within and carried by the tubular shaft 19.

The well known practice of funiversal winding for which the apparatus of this invention is adapted consists of winding the twine in a coil with a comparatively large pitch or distance between each successive turn, and also advancing by-approximately the width of the twine each successive traversal of the winding as illustrated in Figure 6, thus producing an interlocking eflect which makes the C011 self-supporting, and eliminates the necessity of the headed bobbin or spool. To produce this effect with each successive la er of twine on a coil which is constant y growing larger, it is evident that the coil win ing cylinder 17 must be moved traversely in front of the laying device -16, and this traverse motion must be always proportional to the number of turns of the twine that are wound on the coil in a given increment of time. In other words, regardless of the diameter of the coil, the traverse must be moved the same distance for each turn wound upon the coil. However, since the twine is made at a constant rate of speed and delivered by the flyer 9 at a constant rate of speed, the turns of twine wound on the coil in a given increment of time must always be inversely proportional to the variable diameter of the coil during that time interval,

and therefore, the traverse movement of the coil isinversely proportional to the diameter of the coil as well as directly proportional to the number of turns woun on the coil in the given increment of time.

The twine imparts some of the rotative movement of the flyer .9- to the coil,

winding cylinder 17-- and the tubular shaft 19 having the traverse screw the number of turns 32 formed thereon, and this amount is equal to the constant rotative speed of the flyer minus the number of turns of twine which have been wound on the coil in the given increment of time. In order toproduce the type of winding desired and de-- scribed heretofore, the traverse movement of the coil must always be proportional to of twine wound on the coil in the given increment of time, regardes of the diameter of the coil. Y

meaeoe For the purpose of producing the desired speed of traverse movement of the shaft 19, the disk -22 is mounted on the shaft -21 for simultaneous rotation therewith, while permitting free reciprocation of the shaft -19 within the disk by reason of the elongated keyway 23- formed in the shaft 19. The disk -22 is provided at an eccentric point thereon with a transverse opening for the reception of bearing -24- carrying a short shaft -25- which has its opposite ends projecting from the disk 22, and the bearing 24 and the respective projecting end ortions carry spur gears 25 and 2 b th' gear 26 and 2?- being connected to the shaft 25 for simultaneous rotation with the shaft and with each other. The gear 26- meshes with the spur gear28 which is formed with a flange .60 engaged and connected to the hub of pulley 11- for producing simultaneous rotation of gear 28 and pulley 11- so that the gear -28- is rotated at the speed of the flyer .9, theflyer being mounted 19 and keyed thereto as by key upon the tubular journal 61- upon which ournal the and to whic journal the pulley is keyed, as by key 62 and the by 63-. ley 11 drives both the the gear -28, the gear to rotate upon and with -19.

Now, since the gear 26 is the disk 22- as driven by coil-winding cylinder '17- and shaft 19, and at the same time gear 26 engages ear 28 rotating at the speed of the yer, 9, the shaft 25 will be rotated at a speed proportional to the difference between the two speeds, (that is, the speed of the flyer; and the speed of the .shaft 19-) multiplied by the gear ratio. This difference is found to be proportional'to the number of turns of twine wound on the coil in a given increment of time, which in turn is proportional to the traverse movement of the cylinder 17 and the coil carried pulley -llis also mounted, flyer is keyed as flyer 9 and -28 being free respect to shaft thereby.

Through gear 27, driven by shaft 25 and engaging with spur gear -29, the rotative movement of the shaft 25 is compounded by the gear rat-ioand added to the rotative. 'speed of the disk 22, causing gear 29 and the long sleeve -30- in connection with which such gear is formed, to rotate at a higher speed than the winding shaft or screw 19 but at a speed always proportional to the diflerence in speed between the flyer 9 and the coil-winding cylinder -17- plus the speedof the coil winding cylinder -17-. Mounted in or affixed to the sleeve 30- revolved by It will be obvious that the pulaesaeoa ment of the shaft -19 and the co'il-winding cylinder -17 To better demonstrate this point, let F represent the rotative speed of the flyer 9 and therefore the gear 28, and W the rotative speed of the coil-winding cylinder 17- and the shaft 19 with the traverse screw -32 cut thereon. Also let G represent the product of the ratios of gears 23, 26, 27- and Therefore, using these symbols, the rotative speed of the traverse fork -31 will;

be [(FVV)C+W], and the rotative speed of the traverse screw -32 will be W. The difference between these two speeds which al ebraically reduces to (F-W)XC. But F-- representing the speed of the flyer --9, minus. the speed of the coilwinding cylinder 17- equals the number of turns of twine wound on the coil in the given increment of time, and therefore, as proven heretofore, is proportional to the desired traverse movement of the coil winding cylinder 17; Thus, as determined by the ratio. of the gears and the pitch of the traverse screw, any desired pitch of winding ma be accomplished. Further, by proper se ection of the relative proportions of gear ratios and length and pitch of traverse screw. each successive traversal will be advanced if that is desired by a proper amount, so that the twine will be laid in a hard, smooth coil, as illustrated Figure 6.

Purely for the purpose of illustration, the gear 28 may have 46 teeth, while the gear -2G has 12 teeth, and the gear 27 may have 33 teeth, while the gear 29- has 25 teeth for producing the desired relative speeds of the parts with which they are associated in driving relation.

In order to provide sufficient tension in the twine so that it will be wound in a hard, smooth coil, suitable means should be provided for resisting the rotary movement of shaft 19 to a desired extent, and for that purpose, and as illustrative of one such means adapted for effecting it. the disk .-22 is provided with a pulley face -33- adapted for driving a belt -35- and thus imparting a' rotary movement to the pulley --36. The shaft -39' drives in the same direction as the pulley -36 but at a slightly lower rotative speed. Thus,

through the medium of spring 38 and the disk -37- bearing against the web or side of the pulley 36, a retard ing effect is induced in the belt -35 and, I

transferred through the medium of pulley 33 to the shaft 19- and to the winding cylinder 17. By adjusting the tension of the spring 38- any desired retarding effect may beproduced for properly tensioning-the twine during the winding of the coil.

It will be understood from the above de- I scription that the flyer 9 is driven at a substantially uniform rate of speed and that the hollow shaft 19 is driven by the twine'or thread as it is laid upon the winding cylinder -.-17 at a rate of speed somewhat slower than that of the flyer, and that these two rotative speeds are so correlated and applied to the traverse screw of the shaft -19-- by means of the traverse fork as to effect the traverse movement of the shaft 19 at a speed varying in accordance with the requirements for the production of aneifective coil or ball which may, if desired, be of the character known as-universal wind, as illustrated in Figure 6.
