11 Claims. 1

'Ifhis invention relates to a winder, twister, or the like, and more particularly to a means for winding a tail on a package for transferring the yarn from one package to another in the winding of the yarn on a beam or the like.

In the provision of a tail on the end of a yarn package it has been quite usual for the operator to manually wind the tail on the outside of the package and then set the machine in operation for providing th main part of the package. This operation usually results in the provision of a tail longer than is necessary and the uneven lengths of tails in different packages due to the human element of varying the length of material desired. Further, the time of the operator is consumed in this operation, and frequently because of handling of the yarn along this tail portion the same becomes soiled. Further, the twist may vary to an undesirable degree where a twisted yarn is used.

One of the objects of this invention is to provide a device for winding the tail on the outer end of the head of a yarn package without the constant attendance of the operator, and to automatically transfer the yarn from the groove where th tail is provided to the main part of the package for continued winding,

Another object of the invention is to control the length of the yarn which is wound for the tail of the package.

Another object of the invention is to provide a tail which will be less soiled or dirty because of contact with the operators hands.

' Another object of theinvention is to provide a yarn which will be less varied in twist than where wound manually.

Another object of the invention is to reduce the waste because of the exact length which is provided in the tail groove for tying and transferring in any of the following processes.

With these and other objects in view the invention consists of certain novel featuresof construction as will be more fully described and particularly pointed out in the appended claims.

In proceeding with this invention I have provided a guiding finger for directing the yarn out of the path of travel which would normally occur in the windnig of the yarn on the take-up package and then have provided for a movement of this guiding finger after a certain predetermined time so that the yarn will be released therefrom to resume its normal path of travel and then wind on the take-up package core to provide the package of the required size leaving the inner end available as a tail for joining to the outer end of another package for continuous winding of the material in some subsequent process to which th yarn is subjected.

With reference to the drawings, H! and II designate parts of the framework of a twisting or winding machine which is of a length to mount a multiple of winding units, each of which receives power from a shaft extending the length of the machine which in turn is driven from a single source. Brackets l2 support a driving shaft l3-extending the length of the machine along which driving drums M are located for driving the take-up package designated generally l5 and which has its trunnions supported in grooved arms I! to have the core l8 gravitate into surface engagement with the driving drum I! for rotating the package. Each package spool is equipped with heads 19 and 20 and on the outer end of the head 20 there is a grooved flange 2| for winding the tail of the package. An end retaining pin 22 is provided on this flange for securing the end thereto. This grooved flange is notched as at 23 for the passage of yarn therethrough onto the grooved surface 2!, while the head 20 is notched as at 24 so that the yarn may pass therethrough onto the core !8 for Winding by being traversed on this core. A traverse comprising a porcelain guide 25 is notched as at 26 for the reception of the yarn therein, whichguide 25 is reciprocated by a movement of the bar 21 on which it is mounted so as to direct the movement of the yarn from head to head of the package. p A Wire yarn guide 28 from one traverse gudg 25 to the next traverse guide 25 is pro- W e wise or the machine parallel to the shaft l3 upon which the various driving drums are. mounted,

At a location opposite each of the grooved flange 2i, I provide a gear 3? (see Figures 3, 4, andh) which is mounted upon the shaft t ste continually rotate therewith. In this casing "31 'whicht'siirrounds the gear 3?, I mount upon a shaft 38 a mutilated gear 353 having several teeth thereof missing, so that when the mutilated portion is adjacent the gear 3?, there will be no "driving movement imparted to the mutilated gear 39.

A pin 40 is provided onthis gear 39 and a finger.

4| slidably mounted in the casing 39 which when in up position as shown in Figure 3 will projfict a substantial distance above the casing 30. This,

finger is enlarged at its lower end at 42 and provided with a slot 53 of a shape best shown in Figure 7 into which the pm All on the gear 39 extends. The lower wall of the slot 43 is provided with an arcuate depression ily'and the opposite wall portion of the slot 43 opposite to said depression M extends on an upwardly directed curvature providing a cam surface ea. In the normal'position of the finger ii, the pinAd "engages in the'sai'd depression M which is at a position to be vertically in line with the center of rotation of the said gear 39, the said pin being positionedopposite to the mutilated portion of 't'he gear 39 (see Fig. 3). A spring M pulls this flnger'upwardly and as the finger is moved downwardly; this spring is placed under tension tendin'g'to movethe finger again upwardly. Upon the applying oia' manual dou' nwardly iorce on the finger M, the cam surface Mthe'r'eon will move into engagement with the pin 4i) on the left thereof as viewed in 3 to turn the gear 39 in "a clockwise direction to place'its tooth ES'inpQsition to be engaged by the gears: which will nb'w'rotate gear as and through pin 40 en gaging the lower wall of the slot 43 continue downwar'd'movementof the finger M. After the pin L40 has been carried past lower center of the geiar 39 the finger s? Will be f l'dto be movd upwardly under the urge of spring M hut held hack hy' thep'in' ML Upon said gear'fliibeing Ihove'd'out of engagement with the gear 31-,the finger il under tension of spring 44 'will'tdn tinue to be'movedupwar'dly and moving there? withthepin til'to continue the turning of the gear until the force of the spring 44 on the pin lll'is directly vertical of the center of rota} tion of gearyiiil and said pin is again in" en's gagemen't with the said depression 4"! as shown in Fig; 3.' When the finger is in its lowermostposi tion, its top end "all will he suhstantiallyflush with the raised portion filii of the casingpand by reason ofthe'curved surface would permit the yarn 52 to slide over this portion and overhthe top end 5| of the finger fill.

In use, "Yarn 5i. Twill be drawn from a spindle (whichis not shown) upwardly through thepigtail guide hilwhich is located in a plane at right ahglsjto the axis andsubstantially centrally "of thetakeu'p. package id. The operator will then lead the yarn over the guide 3 3 as shown at the left in Figure 2 and wrap the same about the pin 22, then start the package in operation and give a slight pressure on the guide finger M. The unit may from this point on go unattended and the operator may go to attend to replenishing another package. After starting, the yarn will be drawn through the notch 23 in the grooved flange and wound into the groove 2i just so long as the yarn is engaged and deflected by the finger M, as shown at the left in Figure 2, where the yarn now designated 5i being shown at an angle from, the guide 53 to the guide 3%. This guide '4! ish'eing drawn downwardly as the operation proceeds and when the guide ll gets to a level which is below an imaginary line from the armor toa tangent to the top of the grooved flange 2! it will'sli'de over the top 5! of the guide finger and then by reason of its angular relation to the guide 53 will be drawn through the notch fiVir'ithe head of the package and then will rest upon the core of the package E8 and will also slideover the end of the arm M and be received inthe traverse guidefid so thatas the yarn as shown at the right in Figure 2, thereafter will continueon' its usual course reciprocating the yarn hack and forth between the heads is and 20 until the package is of the desired diameten when anew one. will be replenished and the cycle of operations will he continued.

i some casesiit is unnecessary to have a spool with heads'for the yarn package, and in Figure 8 I have illustrated a cylindrical core lid having trunnions 65 at either end and with a groove 62 adjacent one end into which the tail portion of the package-may bewoundby being directed onto the package by the finger G i, after which the yarn will engage the traverse as heretofore mentioned to build up the package 63 into the desired size.
