l2 Claims. 1

The present invention relates to a yarn conditioning attachment for yarn winding machines andthe like.

This application is a. continuation in part of copending application Serial No. 581,500, filed March '7, 1945.

An object of the present invention is the provision of means for intermittently applying a conditioning iiuid to the surface of the drive roller of a yarn winding machine, the liquid being picked up from the surface of the drive roller by the surface of the yarn unit which is in frictional contact with the drive roller and driven thereby for winding the yarn.

A further object of the invention is the provvision of regulating means in combination with means for intermittently applying a conditioning fluid to the surface.. of the drive roller of a yarn winding machine whereby the duration of the periods during which the uid is applied as well as the duration of the periods during which application of uid is interrupted can be controlled to suit different conditions.

Another object of the present invention is the provision of control means for means for intermittently applying a conditioning fluid to the surface of the drive roller of a yarn Winding machine, said control means being connected with the holder of the spindle or cone to which the yarn is wound, and adapted to interrupt operation of the applying means upon interruption of the yarn-Winding operation.

An object of the invention is the provision of an attachment for yarn winding machines, comprising a longitudinal case having a longitudinal open side positioned parallel to the positive driven roller of a yarn Winder and containing a wick projecting through the open side; said case being supported swingably to and from said roller for intermittent contact of the wick with the roller and having a conduit connected thereto for continuously supplying a yarn treating iiuid to the case and constantly wetting the wick thereby preventing undue heating of either the wick or the roller of the winding machine. If the drive roller drives a cone-shaped yarn package the conduit is connected to that part of the Wick case which is opposite the large diameter portion of the package for increasing fluid supply to that part of the wick and of the drive roller where more fluid is demanded due to the larger diameter of the package. The fluid supply conduit communicates with an intermediary iluid reservoir in which the fluid level is maintained at such elevation as to eilect satisfactory wetting of the wick without overflow of the fluid from the wick case.

The present invention provides mechanical as well as electrical means for actuating the wick box or case and for adjusting the duration of contact of the wick with the drive roller as well as the duration of the periods during which such :l contact is interrupted.

Further and other objects of the present invention will be hereinafter set forth in the accompanying specication and claims and shown in the drawings, which by way of illustration show what we now consider to be preferred embodiments of the invention.

In the drawings:

Fig. 1 is a schematic perspective illustration of an assembly according to the invention having mechanical operating and regulating means;

Fig. 2 is a schematic end view of the intermittently acting drive roller wetting mechanism according to the invention and of the means for preventing wetting upon interruption of the yarn winding operation;

Fig. 3 is a wiring diagram illustrating electric operating and regulating means according to the invention.

Like parts are designated by like numerals in I all figures of the drawings..

Referring more particularly to Fig. 1 of the drawings, numeral i designates an electric motor which drives an eccentric disc 2 which moves a push rod 3 to the right when in contact with its free left end. Rod 3 is pivoted to lever I which is fixed to shaft 5. The latter has another lever 8 fixed thereto whose free end is connected by a spring 1 to wick box 6. The vlatter is revolvably mounted on shaft 5 by means of bearings I6 and Il and has an upper longitudinal side which is open and through which protrudes a longitudinal wick 9 inserted in box 6. With every revolution of the disc 2 the shaft 5 is oscillated and lever 8 pulls, through spring l, on case 6 and lifts it to cause the wick 9 to contact the drive roller I0 which is known as a roto-coner roller in commercial winding machines. The pressure with which the wick is pressed to the roller is determined by the tension of spring l. Roller I0 drives the yarn package I8 in the conventional manner. Duration of contact of the wick on the roller is determined by the position of disc 2 with respect to the free end of rod 3 which position may be changed by moving the motor l along the guide rails I I from which it depends. Disc 2 through rod 3 and lever 4 turns shaft i clockwise. The shaft is turned counter-clockwise by the weight of the wick case-and Wick which acts through spring 1 A on lever 8. The frequency of contact of the wick androller I D may be changed by changing the speed of motor I.

Shaft 5 as well as the shaft supporting roller I are carried in bearings mounted on frame portions 2| of. the winding machine.

The wick case is kept filled with yarn treating liquid by means of a liquid supply hose I9 which is attached to a nipple 20 attached to the bottom portion of the wick case at the side which is opposite that portion of drive roller I0 which supports the thick end of the cone which it revolves. Since the portion of Wick which is near the liquid supply through nipple 20 is wetter than other portions a iilm of liquid develops on the portion of the roller I0 which is 'adjacent to the large end of cone I8, thicker than on the other part of the roller, and an' adequate supply of conditioning liquid to the portion of the cone holding more yarn than the small portion of the cone, is assured.

The wick is submerged in the conditioning liquid, the level of which is maintained in the wick box or case by means of a level tank I2. The latter is supplied by a pump I3 placed on top of the main liquid reservoir I4. An overflow pipe i5 maintains the liquid level in the intermediary tank I2.

It is desirable that wetting of roller I0 be stopped whenever the winding operation is interrupted, for example because oi' breakage of the yarn. Commercial winders are provided with automatic mechanisms which remove the package I8 from the drive roller I0. These mechanisms cause the holder 22 of the package spindle to turn clockwise about a support shaft 23 to the position shown in Fig. 2. According to the invention, a iinger 24 is attached'to spindle holder 22. The tip of finger 24 contacts a bracket 25 which is attached to wick box 9, and prevents the wick box assembly from responding to the pull on spring 1 when the spring lever 8 is actuated in counter-clockwise direction by shaft 5. In this way the wick 9 is prevented from touching the roller I0 when no yarn is being wound. When normal operation is resumed, the lever on holder 22 swings counter-clockwise until the yarn package rests on roller Il). Finger 24 swings counter-clockwise at the same time and its tip disengages from the wick box assemblv and frees it to respond to the actions of shaft 5 with itsv arm R and of the spring 1.

Instead of actuating the push rod 3 by a cam or eccentric disc. it may be actuated by the plunger 26 of a solenoid 21 which forms part of the electric operating means schematically shown in Fig. 3. Solenoid 21 is supplied from the electric mains 2R, the flow of current being controlled by the relay operated switch 29. Operation of the latter is regulated by the transmitting tube 30 which passes current upon discharge of condenser C which takes place at the position of two-way switch 3| shown in Fig. 3 which switch is coupled to switch 29. The rate of discharge of C is controlled by variable resistance Rdz's and thereby also the duration of the period during which switch 29 is closed, and solenoid. 21 is energized, and the wick 9 is in contact with roller I0. After discharge of the condenser, tube 30 ceases -to pass plate current and switch 29 opens and the two-way switch is changed over to charge the condenser C through variable resistance .Rch. IThe .time it takes t0 charge C suiiiciently to cause the tube to again draw plate current is determined by the setting of resistance Rch. During the charging period of condenser C switch 29 is open and wick 9 does not contact roller I0. By varying the setting of the resistances Reh and Rdz's the duration of the periods during which no treating liquid is applied to roller` I0 and during which treating liquid is applied can be adjusted to suit different conditions.
