13 Claims. ((1242-53) This invention relates to a method'and means for packaging cord, yarn and the like and more especially to mechanical means for automatically winding a conventional strand of yarn into a 5.. plurality of packages, each package being connected by a portion of the strand.

More specifically, the apparatusprovides means for winding a series of skeins of yarn from one continuous strand, comprising a disk having yarn supporting means thereon with means for intermittently rotating said disk and yarn supporting means, step by step, past a suitable flier whereby the flier will wind a package of yarn upon the yarn supporting means upon each rotation of the disk. The apparatus also has means for traversing the strand as it is wound and means for varying the length of strand in each package. I

It is therefore, an object of this invention to provide a method and'means for winding a strand of continuous length into a plurality of packages with means for traversingthe strand as it isv wound and means for varying the length of strand in each individual package. It is evident, by providing an apparatus of this type that a plurality of these connected packages maybe placed in a suitable container andtheipurchaser of the package may instantly cut off the desired length within certain limits withoutthe necessity of placing a measuring stick thereon. It also provides a cord or strand of the desired length with no knots therein. l I I Some of the objects of the invention having been stated, other objectswill appear when taken in connection with the accompanying drawings,

Referring more specifically to the drawings, the numeral Ill denotes a framework which has aplatform II for supporting motor l2 said motor having a motor shaft [3 and a pulley I 4. A belt 15 is mounted upon pulley l4 and upon a second pulley l6 which in turn is rotatably mounted on stud H. The pulley 56 has integral therewith a smaller pulley 18 upon which is mounted a belt I9, said belt projecting upwardly and being also mounted upon a larger pulley 29 which is rotatably secured on main drive shaft 2!. The stud I1 is supported by a suitable bracket Ila which rests upon the platform I I The main drive shaft 21 is supported by bearings 24, 25, and 26, which are supported at the same elevation, the bearings 24 and 25 being secured to the upper portion of framework It], whereas, the bearing 26 forms a portion of Z- shaped member 21 which, in turn, is secured to the front side of the framework It} Fixedly secured to the front end of shaft 2!. is a pulley 30 which has a belt 3! mounted thereon. This belt is also mounted upon another pulley 32 which is rotatably mounted upon stud shaft 33, said stud shaft being fixedly secured to cross bar 34. The bar 34 has its ends secured as at 35 and 36 to Z-shaped supports 21 and 3-1 which in turn, are supported by the framework Ill.

In order to provide adjustable means for supporting the stud 33, a slot 33a is provided in the member 34 so that the pulley 32 may be moved horizontally to effect the desired adjustment necessary for the proper operation of the parts.

The pulley 32 has integral therewith a change gear. 38 which may be removed from the stud 33 along with the pulley 32 when it is desired to change the gear ratio between the main drive shaft 2| and the flier, which will be presently described. This gear 38 has meshing therewith an intermediate idler gear 39, said gear beingrotatably secured to bracket in. This bracket has vertically disposed slot 48a therein which is penetrated by a bolt ll the bolt also penetrating slot 33m to adjustably secure the bracket in its proper position.

The gearv 39 also meshes with a gear 43 which is fixedly secured to flier shaft 44. This shaft is rotatably mounted-in bearings 45 and 46 which, in turn, are supported by'L-shaped support 31. Qnone end of the flier shaft 44 an L-shaped flier 48 is secured and also a counter-weight '49. A

strand of flexible material 55 is drawn from a suitable pack-age 5i, upwardly through bore 53 in the flier shaft 44, and from bore 53, the strand is drawn through the outstanding leg of flier 43 as at Ma and 48b, whence it is wound around pins 55 and 56 on disk 5?. The disk 5? has a plurality of pairs of pins such as 55 and 56, each pair being adapted to have wound thereon a skein of yarn as shown in Figure 4.

The flier 49 is adapted to be rotated a predetermined number of revolutions while the strand 50 is being wound around a pair of the pins 55 and 55, after which the flier is caused to cease rotation and then the disk 5? is caused to rotate another step so as to position a pair of empty pins 55 and 56 in a winding position. Then the flier resumes rotation and the same operation is repeated.

By providing such an apparatus for effecting this winding operation, any number of skeins of packages of yarn may be wound in series from one continuous length of material depending upon the size of disk ET. The disk 5'! is fixedly secured upon cross shaft 60 which shaft is rotatably moimted in bearings GI and 62 which in turn, are positioned on the top of framework I0.

By referring to Figures 1 and 2, it will be seen that the pulley 25 has integral therewith a small gear 55 which drives the cam shaft 66 in a clockwise direction in Figure 2 through a series of gears El, 68, 69, i and H. The gears 6'! and 68 are rotatably mounted around stud I2 which, in turn, is adjustably mounted in slot 13. This slot is cut in member '54 which is pivoted as at I to bracket iii. The gears 59 and are supported in a like manner by stud shaft H which is likewise adjustably secured in slot IS. The slot I8 is cut in a member I9 which, in turn, is pivoted as at 8:3 to bracket 85. The brackets 76 and BI are supported on top of framework ID.

The cam shaft (35 is supported by bearings 82, 33 and at, the bearings 82 and 83 being secured to the top of framework I0 whereas, the bearing 84 is supported by Z-shaped support 21, (Figure 1). I In order to provide means for causing the flier iii to periodically stop while the disk 51 is turning a new set of pins to winding position, means have been devised for disengaging the source of power from the shaft 2|, to thereby cause the rotation of the flier to cease. This means comprises a cam 35 which has its side normally engaged by a roller 86. This roller is rotatably mounted on the free end of lever 81 which, in turn, is pivoted as at 08 to framework I0. The roller 85 is held in its proper horizontal position by means of a slide 90 which slide supports the free end of pivoted member 8'! (Figures 1 and 7).

The intermediate portion of the pivoted member 87 has a Y-shaped member 9| pivoted thereto as at 92, and this Y-shaped member is adapted to have its upper end fit in a suitable groove 93 in hub member 94. This hub member is slidably keyed on the main drive shaft 2| by means of a suitable k y-way 95, said hub having integral therewith a clutch face 96 which is normally adapted to engage another clutch face 91 which is integral with the hub portion of pulley 20.

Since the pulley 20 is loosely mounted around the main drive shaft 2I, it is evident that the rotation of this wheel will not cause any rotation of the shaft BI until the clutch faces 96 and 91 are caused to be engaged. The clutch faces are normally pressed to engaged position by means of a suitable compression spring 99 which is disposed around the main drive shaft 2| and has one end thereof abutting collar I00 and its other end abutting the hub member 94.

The flier 48 is rotated a predetermined number of revolutions through the members 20, 94, 2|, 30, 3|, 32, 38, 39, 43, and 44 (Figures 1 and 5). At the same time the cam shaft 86 is caused to rotate one revolution through the members 65, 61, 68, 69, I0 and II (Figures 1 and 2). When the cam 85 rotates so that its high side is engaging the roller 86, the clutch faces 96 and 91 will be disengaged thereby stopping the flier 4B, and preventing any further rotation until after the disk 51 has been turned to the new position.

In Figures 1 and 7 a portion 85a is shown acting along with the cam 85, however, this portion is not absolutely essential to the operation of the apparatus since the spring 99 normally holds the roller 85 in contact with cam 85. Nevertheless this portion 85a serves as a positive means for holding the roller in proper contact with the cam 85, if, for any reason, the spring 99 should fail to act.

If, for any reason, the outstanding leg of flier 48 should stop in a position as shown in Figure 3, where one of the pins 55 or 55 would contact this outstanding leg when the disk 51 is turning to a new position, means are provided for positioning the flier in a non-engaging position prior to the movement of disk 57, so that a jamming of the parts will be prevented. I have provided a large gear IOI which is fixedly secured on the end of slow moving cam shaft 66. This gear has one section with only a few teeth therein and the other portion of its face is smooth. Fixedly secured to the flier shaft 44 is a gear I02 which has all of its face smooth except two sections in which there are a few teeth. These teeth are positioned on the gear I02 so that when the flier 48 stops in a position shown in Figure 3, the slow moving cam shaft 66 will cause the teeth in the gear IM to engage a section of these teeth in gear I02 to turn the flier shaft 44 and the flier 48 to a position where the outstanding leg of the flier will not be engaged by either of the pins 55 or 56 when the disk 51 is being turned to a new position,

In Figure 3 the section of teeth in the gear IOI occupies a position immediately after the winding of a skein has begun. When a skein of yarn has been completed and the flier 48 has stopped, ready for the disk to be turned to a new position, then this section of teeth in gear IOI will have rotated in a counter-clockwise manner in Figure 3, to a position adjacent the gear I02. It is therefore, seen that the teeth in this gear will engage a section of the teeth in gear I02 should this gear be stopped in the proper engaging position, whereas, during the normal winding operation, the gear I02 will rotate along with the flier but will not engage the teeth in gear IOI since this gear only makes one revolution per skein.

After the first skein I04 has been wound, a new set of pins is turned to a position where the flier can wind the strand thereon. This turning is effected by means of a Geneva stop movement comprising a pin wheel I05 which is fixedly secured around shaft 66. The pin wheel I05 has a convex portion I 06 which normally coincides with one of arcuate concave surfaces I01 of a star wheel I08. This star wheel is fixedly secured on cross shaft I09 which, in turn, is rotatably mounted in bearings H0 and III secured upon framework I0. The pin wheel I05 has a concave portion I060, adjacent the convex portion I06 and disposed on the flange of portion I 05 opposite'this concave portion 36a is a pin H3. This pin is adapted to move into one of radially disposed grooves H4 which are cut in star wheel I08 to cause the star wheel to rotate, in the present instance, onequarter of a revolution. The pin wheel I05 and the star wheel i 08 work together to make what is commonly known as a standard Geneva stop movement for periodically moving or rotating the shaft I939 a partial revolution. This partial revolution is transmitted tot he shaft 60 and the disk 51 through a driving connection comprising gears H6, H1, H8, and H9, and it should be stated that the movement produced by this quarter revolution, is only sufficient to turn the shaft 50 and the disk 51 one sixth of a revolution to cause a new set of pins 55 and 56 to turn to proper winding position relative to flier 48. The gears H1 and H8 are adjustably mounted in brackets HM and I IBa respectively. 7 Means have also been provided for causing the shaft 56, along with the disk 51, to reciprocate or move back and forth to cause the yarn on the pins to be equally distributed over a given area. That is, a traversing motion is effected during the winding operation. This traversing eifect is produced by a grooved cam I20 and its associated parts which connect this cam. to the shaft 60.

The cam I20 has a zigzag groove I2I in its periphery into which one end of a lever I22 is adapted to fit. The lever I22 is pivoted as at I23 to a bracket I24 which, in turn, is secured to the framework I0. The other end of lever 122 is forked and has suitable pins I25 therein for engaging groove I 25 in pulley I21. This pulley is fixedly secured to cross shaft 60. During the winding of a skein of yarn the cam shaft 05 makes a complete revolution during which time the lever I22 is caused to oscillate about pivot point 523 to cause the pins 55 and 56 to move towards and away from the observer in Figure 1 to give the desired traversing motion, and thereby prevent the yarn from being wound entirely in one plane on the pins 55 and 56.

When the first skein has been wound and the above described parts have been operated to cause the disk 51 to be turned to a new position, it is seen that there is a connecting portion IMb between the skeins. This portion, immediately after the turning or movement of the disk has been effected, will naturally be disposed in the path of travel of the flier 48, therefore, means must be provided for moving this connecting portion of the strand out of the path of rotation of the flier and against the disk 51. A finger I28 has been pivoted as at I 29 to a bracket I30, which bracket is: secured to the side of framework I. The free end of finger I28 is normally held against the disk 51 as shown in Figures 1 and 4 and in this position the finger will engage the intermediate portion H141) and cause it to be pushed out of the path of travel of the flier 43. A torsion spring I3I is adapted to encircle the pivot pin I29 which spring has one end thereof engaging a pin I33 and its other end engaging upstanding projection I28a which is integral with the finger 928. During the normal operation while the strand is being wound around the pins 55 and 55, the finger I28 is held in bold line position as shown in Figure 1 to cause the intermediate portion I04b to be held out of the path of travel of the flier. After the skein or package of yarn has been completed it is then necessary to provide means whereby the finger I28 will be rotated to dotted line position (Figure 1) to allow the disk 51 and its associated pins 55 and 56 to move to a new position. A cam I34 is: fixedly secured on the cam shaft 66 and the face of this cam is adapted to be engaged by one end of a loosely mounted pin I35, said pin being slidably mounted in framework I0 and also in upstanding projection I36 which is secured to bracket I30. A collar I31 is secured to the intermediate portion of this pin to prevent the pin from becoming removed from its bearings. The other end of the pin I35 is adapted to engage the upstanding projection [28a of finger I28 when the high side of the cam I34 moves against the other end of said pin. When this is done the pin H35 is moved toward the observer in Figure 1 to cause the finger I 28 to rotate to dotted line position, after which the disk 51 and the pins 55 and 56 can move to new position, without having the finger I28 disposed within its path of travel.

. Method of operation Briefly, the method of operation of the machine is as follows:

When a complete package of yarn has been wound upon the pins 55 and 56, the clutch faces and 91 are disengaged by the cam 85. This, of course, will stop the movement of the flier 48. Immediately thereafter, the Geneva stop movement comprising pin wheel I and star wheel 508 will turn the disk 51 and its associatedpins to new position. Shortly before the movement of the disk 51 the cam I 34 will move the finger I28 to dotted line position (Figure 1) to allow the movement of disk 51 to take place. After the movement of disk 51 the finger I28 will go back to bold line position under the force of torsion spring I3I. After the finger goes back and forces the connecting portion I Ma against the disk 51 and out of the path of travel of the flier 48, the roller 86 falls off of the high side of cam 85 and under the force of spring 99, thereby allows the clutch faces 96 and 91 to fall into engaged position so that the flier 40 will resume its rotative movement to wind another skein of yarn upon the pins 55 and 56.

After the skeins have been wound upon the pins 55 and 56 an operator usually ties a suitable band i04a around the central portion of the skein and thereafter the same are removed from the pins, connected in series by the portions I04b in a manner shown in Figure 8. While I have shown pins for the purposes of winding a skein, it is evident that only a single pin could be em.- ployed and with traversing mechanism a ball of yarn can be wound instead of the skein.

The pins for supporting the packages may be positioned in any desired manner in disk 51, so as to have longer or shorter skeins. Also the number of pairs may be varied provided the gear H6 is replaced with another gear of such a size as to give the proper rotation to the disk. When it is desired to vary the length of strand in the skeins the gear 33 is replaced with a larger or smaller gear as required.

It is therefore seen that I have provided means for winding a plurality of packages of yarn from a continuous strand with means for automatically moving each package from winding position after it has been completely wound, and simultaneously substituting an empty supporting means therefor, which may be a spindle or a plurality of spindles.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are em ;ployed, they areused in a generic and descriptive sense only, and notfor purposes of limitation, the scope of the invention being set forth in the appended claims.
