COLEMAN, BUFFALO, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO DU PONT RAYON COMPANY, OF NEW YORK, -N. Y., A CORPORATION OF DELAWARE DEVICE FOR APPLYING OIL OR OTHER LIQUID TO THREADv Application filed June 18, 1925. SerialNo. 37,990.

material while the same is being wound on a spool or other support.

In winding a thread-of rayon or other fibrous material on a spool or other support to form a package or roll ready for the market, it is necessary for certain purposes to add a quantity of oil to the thread. In oiling devices as heretofore constructed, a defitity of thread on the support built up and i nite quantity of oil was supplied to the thread, said .oil being picked up by the thread as it passed to the spool or other support. Since the'spool or support in machines of this kind was rotatedat a definite speed of rotation during the entire winding operation, it was obvious that as the quanincreased the diameter of the package or mass, the speed of the thread increased proportionately. In oiling devices heretofore used, an increased quantity of oil has not been successfully supplied to the thread when the same moved at a higher rate of speed. This resulted inan unequal oiling of the thread. the inner portions of the package receiving a greater uantity of oil than the outer portions thereof,

An object of this invention is to provide a liquid applying device of improved construction which compensates for the speed of the.threa"d in such a manner as to supply the liquid to a greater or longer stretch of thread when it travels at a higher rate of speed.

. Another object of this invention is to provide a device of this kind which is entirely automatic in its operation whereby no attention is required to render the compensating feature of the device operative.

An additional object of this invention is to improve the construction of devices of this kind in the other respects hereinafter specified.

Referring to the drawings wherein like reference numerals and characters designate like parts, the reference numeral 10 represents spindles which are adapted to be rotated in any suitable or desired manner, and on which supports, cores or spools X' are adapted to be mounted. These supports, cores or spools are commonly made of paper and conical or cylindrical in shape to adapt the same to readily cooperate with knitting and weaving machines. The reference character Y represents the thread of rayon or wound may be mounted on an upright frame member 11 of the machine. Disposed beneath and/or in the path of travel of the thread Y is a trough or container 12 for the oil or other liquidto be applied to the thread.

The machine is provided with any usual or suitable mechanism for moving the thread Y back and forth lengthwise, of the support or core X to form a substantial frustoconical or cylindrical mass or package of thread thereon; In the drawings I have illustrated a portion 15 of'the thread guide mechanism commonly used in connection with machines of this kind. This thread guide mechanism is mounted on 'a traverse frame or support 16 which is pivoted at 17 .to the frame member 11, and includes a traverse frame counterweight 18 for holding the mechanism 15 in engagement with the outer face of the mass or body of thread on the support or spool X. The thread passes from asupply drum or spool Z through suitable thread guide devices 20 and 21 of usual construction arranged on the oil trough or reservoir 12, see Fig. 2. The thread then passes through a guide 22, arranged above the oil reservoir, from which the thread passes through the tension device indicated generally by the reference numeral 24, and which is also of usual construction, and serves to apply the necessary tension to the thread to enable the same to be uniformly wound on the core or spool X. Another thread guide 25 is arranged above the tension device 24. The thread guides 22 and 25 and the tension device 24 are supported from the frame member 11 by means of a bracket 26. The counterweight 18 maintains the thread guide mechanism 15 in contact with the outer or peripheral surface of the mass or body of thread wound on the core or support X, and as the thread builds up on the core or support, the traverseframe swings about its pivot 17 two different positions of the traverse frame being shown in Fig. 1. All of the parts so'far described have heretofore been used in connection with winding machines and of themselves constitute no part of this invention.

The oiling or wetting of the thread preferably, but not necessarily, takes place intermittently, the excess oil from the oiled portions of the thread which was oiled by contact with the wiper is thereby deposited on the various tensions and guide members. The portion of the thread which does not contact with the wiper receives oil from these members so that a substantially uniform oiling of the thread takes place. In accordance with my improved device, the

. lengths of contact or intervals of time during which oil or liquid is applied to the thread is increased as the speed of the thread increases, with the result that after engaging the various guides and tension member approximately the same quantity of oil is applied to any given length of thread at all times during the winding of the thread. In order to accomplish this 1 result, a number of different mechanisms may be used, the one shown in the drawings by way of an example embodying one form of my invention including a rotary oiling or wiper member 30, one of these members being employed in connection with each-thread. This rotary member is mounted on a-driven shaft 31, and is provided with one or more peripheral wiping portions 32 which are adapted to dip into the oil during the rotation ofthe oiling member, and also to contact at.intervals with the thread and wipe the oil on the thread, two of these peripheral portions being shown in the construction illustrated. .Each peripheral portion 32 has an arcuate outer surface" substantially concentric with the axis of rotation, of the shaft '31. These arcuate surfaces may be connected to the hub portion 33 of the rotary member in any suitable manner, for example, by means of radially extending webs or arms 34. The hub portion 33 of the rotary oiling member is rotatably and slidably mounted on the shaft 31 whereby the rotary member may be moved lengthwise of the shaft. In the particular construction shown for this purpose, the shaft 31 is provided with a keyway or groove 36, and the rotary member is provided with a key or finger 37, see Fig. 2, removably secured thereto, and adapted to extend into the keyway 36.

The arc-shaped wiper faces 32 of the rotary oiling member are substantially wedgeshaped, or in other words, the faces 32 are provided with converging sides. The thread is guided by means of the thread guides 21 and 22 whereby it will touch the peripheral portions of the oiling members at intervals during the rotation of the oiling member. By making these peripheral portions 32 of wedgeshape, or with converging sides, it will be obvious that the arc of the oiling surfaces 32 which contacts with the thread when the thread is guided as shown at the left side of Fig. 1, is much greater than when the thread 1s guided as shown at the rightside of Fig. 1. The shaft 31 may be driven in any suitable manner,

for example by means of a cone pulley 39 which makes it. possible to vary the speed of the shaft. The variation in speed of the shaft controls the number of times per interval of time that the wiping surfaces contact with the thread,"and thus control the quantity of oil supplied to thethread. The rotation of the shaft 31 is preferably in the direction indicated by the arrows in Figs. 2, 4 and 5.

Mechanism is provided whereby the oiling members 30 may be moved relatively to the thread in accordance with the diameter of the mass or body of thread which has been woundupon the spool or support X. In the particular construction shown for this-purpose, a rod or connecting link 40 is provided, one end of which is pivotally connected to the counterweight 18, and the other end of which terminates in a fork 41 which is adapted to enter into an annular groove 42 formed in the hub portion of the oiling member 30. The forked member 41 in the particular construction shown, is provided with a laterally extending arm 43 entering into a hole or hearing in a lug or 17, due to the contact ofthe-thread guiding I device withthe outer surface of the mass or body ofthread on the support or spool X.

- The movement of the traverse frame is communicated to the oiling member by' the link 40 so that this member moves lengthwise of the shaft 31 to present different portions of the oiling surface 32 thereof to the thread passing to the spool or support X.,

'By arranging the-pin 48 in different holes 47, the amount of movement imparted to I the oiling member may be varied. It will be obvious that when the winding of the thread on the spool or support X is beginning,'the thread will be moving at a relatively slow speed, and will consequently contact with V the portions of the wedge-shaped faces 32 nearest to the apex of the wedge, so that the thread will contact with the oiled outer surface of the oiling member for acomparatively small portion of the rotation of these members, it being understood, of course, that the oiling members 30 and shaftBlare ro: tated at a substantially constantlspeed. As the speed of the thread increases, the movement of the mechanism is such that the thread will contact. with the wedge-shaped faces .32at a greater distancefrom the apex I thereof so that the arc of contact will be greater, and consequenty the thread will contact with the oiling member through a relasurfaces of the members 30 are practically; portions of a cylinder and it will be obvitively greater length or stretch. The oiling ous that the thread, when contacting with the smaller or narrower portions of the cylinders, as shown in Fig. 4, will be in contact with the oiling surface for a much smaller length or stretch than when contacting with wider portions ofthe cylinders, as shown in Fig. 5. By means of this construction in eluding guiding and tensioning' devices a uniform oiling of the thread is insured and the operation of the mechanism is entirely automatic.

It will, of course, be understoodthat liq-- uids other than oil may be applied to the thread by means of the mechanism described.
