viding moistening apparatus wherein the quantity of liquid transferred to a textile thread or yarn may be readily varied.

A still further object of the invention includes the provision of a roller adapted to betangen- "tally engaged by a longitudinally moving threadl or yarn 'and means for supplying liquid in the form of a lm to the periphery of the roller'and means for controlling the quantity of liquid carried by the` periphery of the roller.

A more specic obiect of the invention resides in providing a plurality of rollers each carrying a film of conditioning liquid including means for selectively moving the rollers into engagement with the thread so as to control the quantity lof conditioning liquid transferred to the thread or lyarn.

Another and more specific object of the 4invention includes a roller and means for driving the roller at different speeds including means. for supplying a nlm of liquid to the'periphery of the .roller and a second roller movable into frictional engagement with the first roller so as to be driven thereby and receive a fllm of liquid from'the driving roller with both of the rollers engaging the thread to be moistened.

Other features and objects of the invention will be apparent `from a consideration of the accompanying drawing and the following detailed description wherein an exemplary embodiment of theinvention is disclosed.

In the drawing:

Fig. 1 is a general organization view illustrating the moistening apparatus in elevation and partly in section.

Fig. 2 is a perspective' view'of the main roller i end of the moistening apparatus.-

Fig. 6 is a longitudinal sectional view of one of the rollers oi' the' moistening apparatus.

Referring 'to the drawing there is shown in Fig. .l at I0 a spool or bobbin of a conventional typeontowhichthethreadmayliestoredby` winding the thread on the bobbin III. The bobbin may be driven by means of a shaft Il which is rotatably supported in Winding apparatus in a well known manner. The bobbin III is preferably arranged in a horizontal manner above the moistening apparatus hereinafter described so that rotation of the shaft II will cause the thread to move Vlongitudinally in an upward direction.

In carrying out the invention a roller l2 is supported for rotation within a frame lf! which;

includes two end plates I6 and I1. The roller I2 is suitably journaled in the end plates i6 and I1. A shaft I8 is provided for driving the roller I2. Power is transferred to the shaft I8 from a driven shaft I9. Suitable means may be provided between the shaft I9 and the shaft I8 for varying the speed of the roller I2. Such speedvarying means may take the form of reversed cone pulleys 2l connected by means of a belt 22 as shownin 1.

4512 by any suitable means such as a threaded liquid supplied to the wick 23 may thus be varied 'I'he invention includes means for supplying a iilm of liquid to the periphery of the roller I2.

Such means may'consist of a wick 23 formed of any-suitablematerial such as felt but the wick may be formed of sponge or chamois or like materials. The wick 23 preferably extends along the entire length of the roller I2 as shown in` Fig. 2. The Wickis supported in an operable position adjacent the roller I2 by means of an elongated cup-shaped member 24 which may be substantially U-shaped in section and extends along -the entire length of the wick 23. Liquid is supplied to the wick 23 from a tank or container 2 6 connected to the member 24 byI means of a exible tube 21. The elongated cup-shaped member 24 may be regarded as a trough and is supported in such a manner than the liquid supplied thereto will be retained therein and absorbed by the wick 23. The tankl 2E is adapted to receive a supply of suitable conditioning liquid for the textile thread or yarn and the container- 26 is mounted so 'as to be raised or lowered with respect tothe wick 23 `and the roller shaft 28 and a handwheel 29. 'Ihe pressure of the by raising or lowering the tank 2G. Thus `the quantityV of liquid conveyed to the periphery of the roller I2 may be varied by changing the position of the tank 26.

The wick means may also extend from the trough 24 into the tank 2i as shown in Fig. l.

The tank 26 may then be lowered below the level of the trough 24 but liquid or moisture will be transferred from the tank to the roller I2 by capillary action of the wick portion V25 in the- Y H tube 21.

The wick 23 engages the periphery, of the roller I2'l andthe pressure of the wick 23 on this roller vapproximate mid-point of the roller it.

3| to alter -the pressure of the wick 23 on the roller.

In carrying out the invention a thread or yarn` 34 to be stored on the bobbin l@ is guided transversely over the periphery of the roller i2 carrying the film of liquid. The thread 3d is maintained substantially in tangential engagement with the periphery of the roller l2 by means of a fixedl thread-guide 3G such as a slub catcher of a winding machine. The thread-guide or slub catcher 36 is preferably arranged below the The thread 34 is preferably moved in an upward direction over the roller i2 by rotation of the bobbin til and guided onto the rotating bobbin by means of a second thread-guide ill. The moistening apparatus or the roller i2 is so positioned with respect 'to the bobbin it and the thread-guide di that the thread or yarn 3d will bbe constantly maintained in engagement with the periphery of the roller i2. The thread-guiding means 3? is also reciprocated longitudinally of the moistening apparatus so as to properly guide the thread 3d onto the bobbin lll. Such reciprocating movement ci' the thread-guiding means 3l may 'be accomplished by means of a.

cam di which may be driven from the power I arms it as shown in Fig. 6. The arms do are secured to a shaft i which is journaled inthe end plates le and il. The shaft d3 ext:.ds beyond each end of the roller d2 and these ends project through slots 136 in the end plates it and il: -The roller i2 may therefore swing on the ,shaft 5l so that the periphery of the roller d2' frictionally engages the periphery of the roiler y i2.v A part of the liquid carried by the roller it,

is therefore conveyed to.the roller i2 and the ro1le`r=42 is rotated by the frictional engagement thereofwiththe roller l2. In such a position as shown in Fig. A3,theroller 52 is adapted to engage-the longitudinally,l moving thread 3d and transfer' additional liquid from the periphery thereofto the thread or yarn.

The roller t2, however,` may be retracted from the. position illustrated in Fig. 3 by means of a handle 52 carried by an arm 48.' When the handle 52 is raised the ends of the shaft d3 move in the slots i6 so that the roller 42 may be moved from engagement with the 'roller I2 and also from engagement with the thread 34. The roller l2 may be-retained in the retracted position by means of a lever 53 pivotally mounted on the end plate H. The lever 53 is provided withl an arcuate recess 54 for partly embracing this end of the shaft 43 in an elevated position in'the` slot fit.

shaped recess 56 for retaining the shaft 43 in a lowermost position in the slot 46.

A third roller 51 may be provided for receiving liquid from the periphery of the roller 42 and the roller El is also driven by frictional engagement with the roller 42. rThe roller 5,1 is pivotally mounted in a' manner similar to the yarrangement shown and described in connection with the roller 42. Thus, by raising the arm 58 the roller 5t' .may be removed from engagement with the thread 3d and fromengagement with the 'relier #it and retained in such retracted posi- .ns of a lever Sil pivotally mounted on it adjacent a shaft Si for the roller rs 53 and @il are yieldably biased by means of tiring 52.

Thus, t uantity of liquid transferred to the thread or @d may be furthervaried by employing the relier t2 in addition to the roller i2 and a still larger quantity of liquid may be conn veye'd'to the thread or yarn 31% by moving the roller 5l inte frictional engagement with thev roller d2 and into engagement with the thread 3d. Under such circumstances the liquid film supplied to the roller l will in part be transferred to the roller t2 and a portion thereof conveyed therefrom onto the periphery of the roller 5l. The liquid carried by all three rollerswill therefore be transferred to the longitudinally moving thread or yarn 3Q. l

It is to be further noted that the speed at which the rollers @it and 51 are driven may also be varied by the speed-changing arrangement `between the shafts i8 and i9 since the roller d2 is driven by the roller i2 and the roller 5l is driven by the roller d2. The liquid transferred to the rollers da and di may also be varied by adjusting the pressure of the Wick 23 -on the rollerl l2 and by varying the height of the tank 26.

When it is desiredtc decrease the quantity of liquid imparted to the thread or yarn 3d the roller d? may be retracted by raising the handle 58 to remove the roller di from engagement with the thread Stand the roller d2. The roller 5l will be retained in the retracted position by means of the lever il. Ei' a still smaller quantity of liquid is to be transferred to the thread or yarn 3d the roller ft2 may be removed from engagement with the thread et by raising the handle 52. The roller t2 will thereby be removed from driving engagement with the roller i2 and the roller di will be retained in a retracted position by the lever 53.

The roller l2 may be rotated in either direc tion. When this roller is driven so as to,.rotate with the periphery thereof moving in a direction opposite to the movement of the yarn Sti more moisture will be transferred to the thread than when the roller l2 is rotated in a clockwise direction in Fig. 3. It will bev further appreciated that any change in the rotating direction of the roller i2 will reverse the rotation of the rollers B2 and 5l to further alter the moisture transferred from these rollers ,to the longitudinally moving -thread or yarn.

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