(c1. m -a) This invention relates to improvements in methods and apparatus for winding skeins of yarn.

The present invention has for'its 'principal object to provide improved methods and apparatus for winding skeins of yarn. v

Other objects and advantages of the invention will be apparent from the following description and accompanying drawings which show'prefrred embodiments of the invention. s

' The means for carrying out the invention as shown in Figure 1 comprises the reel or. swift indicated by reference character Imounted on the central shaft 2 which is supported in the frame II and driven by suitable means which are not shown, The yarn A is directed to the reel or swift by the guide 4 carried by the traverse member comprising the bell crank having arms 5 and 6. and pivotally mounted on the frame at I. The traverse member is actuated by the linkl which is pivotally connected at one end to the arm I and at the other end to the engage the stop member.

gear 9. The gear 3 is driven by the gear l0 which is fixed tothe central shaft 2. The gear 9, in rotating, reciprocates the link 8 and causes the traverse member to move the thread guide back and forth across the face of the reel or swift.

The connection of the link 8' with the gear 9 is shown more particularly in Figures 2 and 3. The link is journaled at one side of the gear on the eccentric portion I2 of the pin I3 which is journaled in the gear 9. The ratchet wheel I4 is fixed on the pin on the other side of the gear. The star wheel I5 is pivotally mounted on the pin IS on the same side of the gear as the ratchet wheel. The star wheel has a hub portion II which. is-eccentric to the pin and on which is pivotally mountedthe pawl Ill. The spring member l9 urges the pawl into engagement with teeth on the ratchet wheel. In order to prevent undue rotation of the ratchet wheel, brake means are provided comprising the spring clip 22 fastened to the gear by the screw 23 and having one end pressed against the face of the ratchet wheel. The stop member 20 issupported 'on the pin 2|. in position to contact the teeth on the star wheel and can be moved to inoperative position, when desired, by being swung r'ccates the link 8 back and forth. The star wheel is carried around by the gear and the teeth As the teethof the star wheel are retarded by the stop member, the star wheel is in effect rotated intermittently a part of 'arevolution 'on the pin 16 relative to the gear for each revolution ofthe gear. The eccentric hub of the star wheel in rotating about the pin 16 actuates the pawl which rotates the ratchet wheel. The ratchet wheel rotates the pin [3 and shifts the axis of the eccentric por- 1 tion relative to the axis of the gear on which it is mounted. The effect of shifting the axis of the eccentric portion isto vary the length of stroke of the link and the path of the thread guide back and forth across the face of the reel or swift and accordingly thepath of the yarn being wound on the reel. This is shown in Figure 7 where reference characters B, C, D,and E.

indicate that the distances that succeeding strands of yarn are placed apart on the reel vary during the winding operation.

- In the form of the invention shown in Figure 5 the length of the traverse of the threadrguide across the face of the reel remains substantially the same, while the portion of the face of 'the reel vover which the thread guide traverses, changes continually during the winding operation. This form as shown comprises the reel or swift 25 mounted on the central shaft 26 which is supported in the frame 33 and driven by suitable means which areunot shown. These parts are the same as the corresponding parts shown in Figure 1. The yarn is directed to the reel or swift by the guide member 21 which is carried by the traverse member 28. The traverse member and the link 29 are fixed to the rotatable shaft 43. The traverse member is actuated by the link 3| which is pivotally connected at one end to the gear 32 and at the other end to the link 29. The gear 32 is driven by the gear 34 which is fixed to the central shaft 26. The gear 32 in rotating reciprocates the link 3| and causes the traverse member to move'the thread guide back and forth across the face of the reel or swift. The link 3| is pivotally connected to the.

link 29 through the eccentric portion 36 of the pin 34 which is pivotally mounted near the end of the link 29. The ratchet 35 is fixed to the pin 34. The star wheel 49 is fixed to the pin 38 which is pivotally mounted on the link 2-9. The star wheel has an eccentric hub portion 39 on which.

- star wheel is carried back and forth on the link 29 and the teeth engage the stop member. As the teeth of the star wheel are retarded by the stop member the star wheel is in effect rotated a part of a revolution during each oscillation of the link 29. The eccentric hub of the star wheel in rotating actuates the pawl which rotates the ratchet wheel. The ratchet wheel rotates the pin 34 and shifts the axis of the eccentric portion 36 relative to-the link 29. The eccentric portion, in shifting its axis, moves the link 29 relative to the link 3|. The stroke of the link 3| and of the thread guide on the traverse member back and forth across the face of the reel remainssubstantially the same during the winding operation, however, the link 29 in shifting relative to while the portion of the reel over which the thread guide traverses, changes continuously duringthe winding operation. This embodiment comprises the reel or swift 45 mounted on the central shaft 46 which ,is supported in the frame 54 and driven by suitable means which are not shown. These parts are the same as the corresponding parts shown in Figures 1 and 5. The yarn is directed'to the reel or swiftby the guide member 41 which is carried by the traverse mem-' ber comprising the bell crank having the arms 49 and 49 which is pivotally mounted to rotate about the shaft .65. The link 59 is mounted to pivot freely on the shaft 65. The traverse memher is actuated by the link which is pivotally connected at one end to the gear 52 and at its other end to the link 59. The gear 52 is driven by the gear 53 which is fixed. to the shaft 46. The gear in rotating reciprocates the link 5| back and forth and oscillates'the link 59 about the shaft 65. The ratchet wheel 58 is fixed to the pin 66 that is pivotally mounted in the link 59. The pin has an eccentric portion 51 which engages the sides of the slot 56 in bell crank arm 49; The star wheel 63 is fixed to the pin 62 which is pivotally mounted on the link 59. The star wheel has an eccentric hub portion 6| on which the pawl 69 is pivotally mounted. The pawl is held in engagement with the teeth on the ratchet by means of the spring 59. The stop member 64 is pivotally supported on the frame in position to contact the teeth on the star wheel and may be moved to an inoperative position out of the path of the teeth.

In the operation of this embodiment the gear 52 in rotating reciprocates the link 5| which oscillates the link 50 on the shaft 65. The eccen-.

tric portion 51 of the pin 66 carriedby the link 59 oscillates the arms 48 and 49 of the bell crank about the shaft 65 and causes the thread guide to move back and forth across the face of the reel. The star wheel is carried back and forth as the link 59 is oscillated and the teeth engage the stop member. As the teeth of the star wheel are retarded by the stop member, the star wheel is in effect rotated a part of a revolution during each oscillation of the link. The eccentric hub of the star wheel in rotating actuates the pawl which rotates the ratchet wheel. The ratchet wheel in rotating shifts the axis of the eccentric portion 51 of the pin which shifts the arms of the bell .crank relative to the link 59. In this embodiment the length of the traverse of the thread guide across the face of the reel and the distance between succeeding strands of yarn indicated by reference characters F, G, H and I in Figure 8 remains the same while theportion of the reel over which the guide traverses continually changes during the winding operation.

In accordance with this invention, the thread guide is shifted, in addition to the usual traverse movement, an amount sufficient that successive strands of yarn directed to the same portion of the reel are arranged side by side as shown in Figure 4.

While preferred embodiments of the invention have been shown, it is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
