s claims. (C l. en -3s) The present invention relatesto apparatus for treating thread or yarn and more specically pertains to an arrangement for applying moisture or liquid to the thread ordyarn as the same is wound on a thread carrier or bobbin.

An object of theJ invention resides in providing means for supplying conditioning liquid to yarn as the yarn is being wound on a rotating carrier member or bobbin so that the conditioning liquid will be supplied to each layer of yarn wound on the carrier member.

A further object of the invention includes means for supplying moisture to thread as. the

thread is wound on a bobbin including means for varying the quantity of liquid supplied to the thread. 1

A still further object of the invention resides in providing a brush having bristlesvwith the brush mounted to engage the thread being wound on the bobbin including means for supplying conditioning liquid to the bristles of the brush whereby the liquid is transferred to the thread as the same is wound on the bobbin.

A more speciilc object of the invention pertains .with thread wound on the thread carrier and means for swinging the brush away from the thread carrier when rotation thereof is stopped.

Other objects and features of the invention will be more apparent upon a consideration of the accompanying drawing and the following de scription wherein. an exemplary embodiment of the invention is disclosed.

In the drawing: Fig. 1 is a diagrammatic view partly in section illustrating the general organization of apparatus embodyingthe invention.

Fig. 2 is an end elevational view of the lar 4 rangement shown in Fig. 1.

Fig. 3 is an enlarged plan view of the brush with parts thereof broken .away to illustrate means for supplying liquid to the bristles.

Fig. 4 is a transverse sectional view of a modl- -ned bmsh. i

' ing machines.

Referring to the drawing there is shown at Il a carrier member or .a bobbin of a conventional type suchy as employed in some types of wind- The carrier' member Il is preferably arranged with the axis thereof in a horlzontal, manner as shown in Fig. 1. The thread or yarn carrier or bobbin is rotated by means of a driven shaft i i. The shaft Il is driven from a suitable power source as i's lcustomary in winding machines. Power is transmitted from the shaft il to the shaft I2 through a clutch mechanism indicated generally at I4. Thus, the thread carrier I0 may be rotated by moving the parts of the clutch i4 into driving engagement and the bobbin l will of course be stopped when the shaft I2 is de-clutched from the shaft Il.

A thread or yarn I'Ijlto be wound on the car. rier member I0 extends through suitable tension means diagrammaticallly illustrated at It in Fig. 2. The thread I1 after passing through the tension means Il is wound on the bobbin Il in the i direction of thev arrow shown in Fig. 2. 'I'he thread I1 is also guided or bodily moved longiyarn is arranged on the bobbin II after which vanother layer is wound on the layer previously wound on the bobbin.

- to the thread or yarn as the same is wound on the bobbin Il. Such means may for example include a brush shown generally at Il having bristles Il for engaging the thread or yarn wound on the bobbin Il. The brush is preferably mounted above the thread carrier il as shown in Fig. 2. Thus. the brush which is suptoning liquid will flow or creep downwardly on the bristles It.' 'I'he brush Il is also mounted in such a manner that the bristles will engage the bobbin `or the thread thereon and the bristles preferably extend in the rotating direction of the thread carrier Il. In other wordsthe bobbin lIl is rotated in a clockwise direction when the bristles are arranged above the carrier member as shown in Fig. 2.

vThe brush may be formed of a substantially rigid-pipe 2l rotatably mounted in suitable brackets 22 which may be supported on the winding apparatus. The bristles may extend into the pipe 2| as shown in Fig. 3. A suitable casing Il may be provided for enclosing portions of the capillary action of the wick 3|.

bristles adjacent the pipe 2I. This casing 23 is suitably secured to the pipe 2 I The moistening apparatus includes means for supplyingliquid to the bristles I9. Such means may include a tank 26 for storing a quantity of conditioning liquid therein. The tank 26 is arranged to be raised or lowered with respect to the position of the brush I8 by any suitable means such as a threaded shaft 21 and a handwheel 28. The tank 26 may be connected to the pipe 2| by means of a flexible tube 29 to permit relative movement between the pipe 2| and the tank 26. Thus, by raising the tank'26 more liquid will be supplied to the bristles I9 since the pressure of the liquid within the pipe 2| will thereby be increased. Likewise, less liquid will be supplied to the bristles of the brush when the handwheel 26 is rotated to lower the tank 26. The vertical movement -of the tank 26 thus provides means for varying the amount of moisture conveyed to the thread or yarn being wound on the bobbin I6.

The arrangement may include wick means within the pipe 2| and a wick 3I may extend therefrom through the exible tube 29 into the tank 26. The wick 3| will thus absorb a supply of the conditioning liquid from the tank 26 and retain the liquid so as to make the moisture available to the bristles I9. With such an arrangement and when the tank 26 is raised with respect to the brush I8 the wick 3| will be saturated at a faster rate thereby feeding more liquid to the bristles which in turn will supply a greater quantity of the liquid to the yarn on the surface of the carrier member I0. By lowering the container 26 the saturation of the wick will be reduced and consequently the transfer of liquid by means of the bristles I6 onto the surface of the thread or yarn on the bobbin I6 will thereby be reduced. Even when the tank 26 is moved to a position Ibelow the level of the brush I8 liquid will nevertheless be conveyed to the bristles I3 by The quantity of liquid applied t the thread being wound on the bobbin I0 may be further controlled by varying the speed of the rotating thread carrier.

y When the rotation of the bobbin I0 ceases 'it is advisable to remove the brush with the bristles I9 thereof from engagement with the thread or yarn on the bobbin. Any suitable means may be provided for moving the brush I8 to a position preventing the bristles I3 from transferring moisture tothe thread on the bobbin. Such means for example may include a handle 32 which is mounted to rotate a shaft 33. A bevelled gear wheel 34 suitably keyed to the shaft 33 will be rotated when the handle 32 swings in the directionof the arrow 36. Such rotation of the gear 34 will rotate a beveled gear wheel 31 secured to the pipe 2| so as to rotate the rigid pipe in the brackets 22 and swing the brush I8 away from the bobbin I6. A lever 36 is also pivoted with the rotation of the shaft 33 by the handle 32 to de-clutch the shafty I2 from the shaft II. For this purpose one part 4| of the clutch is provided with a circumferentially extending groove into whicha lug carried by thelever 38 extends. The groove in the member 4I may be sufficiently large to permitl such swinging movement of the lever 38. Thus, when the shaft I2 is (ie-clutched from the shaft II to stop the bobbin I0 thebrush I8 will be removed to a position -where the bristles I9 will no longer engage the threadvon the bobbin I0. F v

The invention also includes automatic means for moving thebrush I 8 to aposition for preventing liquidv from being transferred to the thread on the carrier member I0 when the yarn breaks or in the absence of thread tension. Such means may include a feeler arm 43 pivotally mounted to swing on a pin 44. Thus, when the thread I1 breaks or in the absence of tension thereon the feeler arm 43 will swing downwardly in Fig. 2. A suitable arrangement for swinging the Ibrush I8 or rotating the pipe 2| when the thread I1 breaks or in the absence of tension may include an electromagnet 46 which is supplied with current from a suitable source such as a battery 41 when the contacts 48 are closed by the downward swinging movement of the feeler arm 43. When the electromagnet 46 is energized an armature 5I thereof will be drawn into the coil of the electromagnet-l to swing the lever 36 to thek left in Fig. 1 and rotate the shaft 33 in a clockwise direction. Such rotation of the gear 34 will cause the gear 31 to be rotated and swing the brush I 8 away from the bobbin I6. The armature 5I being connected to the lever 38, the clutch member 4I will also be moved to the left to interrupt the driving connection' between the shafts I I and I2 and thus stop the bobbin I when the thread breaks or in the absence of tension.

The brush I8 is preferably mounted above the bobbin I6 so that the brush will normally swing downwardly to lay on the thread carried by the bobbin. Yieldable means, however, may be provided for more positively moving the bristles I3 of the brush into engagement with the thread or yarn being wound on the ythread carrier. Such yieldable-means may consist of a relatively light torsion spring 56 biasing the brush into a position whereby the bristles I9 engage the thread on the bobbin I0.

'I'he means for supplying liquid to the bristles I9 of the brush may be constructed as shown in Fig. 4 wherein a plurality of small wicks 3|a are arranged within the p ipe 2l and these'wicks may also extend into the tank 26.

While the invention has been described with reference to specific structural details it Will be appreciated that changes may be made therein by those skilled in the art. Such changes may be made without departing from the spirit .and scope of the invention as set forth in the appended claims.
