No. 707,382 15 Claims. (Cl. 57-120 This invention relates to spinning and twisting rings, and is more particularly concerned with spinning and twisting rings for textile fibers and holders therefor incorporating novel and improved means for maintaining effective and efiicient lubrication for a traveler supported by the ring and rotating thereover.

A primary objective in the design and construction of traveler rings for twisting and spinning of the textile industry has been to provide simplicity, durability and economy of manufacture without sacrifice of efliciency in operation. Such rings are required by the industry in the hundreds of thousands, and it will be understood that even a slight saving in the cost of an individual ring represents a substantial factor of economy in the total industry. Since the speed of rotation of the traveler about the ring is in the thousands of revolutions per minute, one of the important considerations in the design and construction of such rings is the problem of lubrication and coolin in order to reduce friction and enhance the useful life of both ring and traveler. Such lubrication has in the past been achieved by the use of oil saturated wick structures over which the traveler passes to maintain a lubricant film thereon. Several problems arise with respect to such lubrication; one being the necessity for continuous replenishment of lubricant to the individual rings, another is the danger of contact of the lubricant with the material being spun. With the advent of nylon or like plastic travelers for the rings, heating by frictional contact has become increasingly serious and thus minimum contact of the traveler with the ring is desirable. If contact of the ring with lubrication wicks is presented, carbonization of the wick will ensue and oil flow will be retarded. Where thousands of rings are employed in a single mill, it will be seen that the problem of maintaining adequate lubricant is an ardous and time consuming operation while the soiling of the spun material by contact with the lubricant may cause the rejection of expensive quantities of spun or twisted material.

The present invention provides a novel, simple and improved construction made of a minimum number of simply and easily formed parts providing a rugged and durable construction together with means for maintaining a sump or reservoir for lubricant and coolant minimizing the necessity of continuous replenishment of lubricant together with a structure by which the contact of the material being spun with the lubricant is inhibited. The ring of the present invention also permits replenishing of the lubricant without cessation of spinning operation. In operation, the traveler has minimum contact with the ring and no contact with the lubricant supply wick. More specifically, that form of the invention here shown by .way of example may be generally defined as comprising an outer casing defining a lower inwardly extending lubricant supply reservoir or chamber from which the lubricant is led upwardly by capillary action through an annular wick to be transferred inwardly and adjacent the path of travel of the outer surface of the traveler body by capillary means. The traveler is arranged to move over the ring with minimum frictional contact and hence with minimum heat generation, being air cooled by virtue of its velocity. No contact between the traveler and the oil wick is permitted, lubricant moves from the wick to the ring by forces arising from the velocity of the traveler, hence no burning or carbonizing of the wick is permitted. The construction and arrangement of parts is such that while the inner surface of the traveler body may be copiously supplied with adequate lubricant, ex-' cess lubricant will be returned to the sump for recirculation by discharge from the traveler through centrifugal force. In carrying out the invention the number of parts has been maintained at a minimum, and the construction of each is simple and well designed to meet the demands of economic manufacture whereby the ring may be produced and distributed at a cost representing a substantial saving to the industry.

It is therefore among the primary objects of the present invention to provide a novel and improved spinning and twisting ring of simple, rugged and durable construction incorporating improved means for maintaining adequate lubrication for minimum friction and ample thread space for a traveler mounted thereon and rotating thereover.

Another object of the invention is to provide a twisting and spinning ring incorporating therein a lubricant reservoir for maintaining an adequate supply of lubricant and coolant over a substantial period of time, thus avoiding the necessity of repeated applications of lubricant at frequent intervals, and one in which the lubricant may be replenished without termination of the spinning operation.

It is also among the objects of the present invention to provide a device of the character set forth including means for insuring a circulation of lubricant so as to insure an adequate supply of lubricant at all times to the traveler without direct contact of the traveler with the lubricant supply wick, and hence without wear or charring or damage of such wick.

A further object of the present invention is to provide a ring and traveler combination by which minimum traveler contact with the ring is insured while maximum cooling and adequate lubrication is provided and contact of lubricant with the material being spun is inhibited so as to insure a clean finished product.

The objectives of the present invention also include that of providing a twisting and spinning ring of simple construction, the parts of which may be readily formed by a simple manufacturing method and assembled without special tools or skills so as to provide a device at a cost representing a substantial saving to the industry.

Numerous other objects, features and advantages of the present invention will be apparent from consideration of the following specification, taken in conjunction with the accompanying drawing in which:

FIG. 1 is a perspective view, partly broken away, of one embodiment of the present invention.

FIG. 2 is an enlarged vertical cross section through one side of the ring illustrating the lubricant passage from sump to discharge wick.

FIG. 3 is a similar cross section illustrating one of the assembly features and the lubricant replenishing means.

Referring now more particularly to the drawings, it will be seen that the present embodiment of the invention includes an external supporting body of generally circular form including a cylindrical side wall 10 open at the top in a plain cylindrical vertical edge 11 and formed at its lower edge with an inwardly extending annular horizontal bottom Wall 12. The wall 12 terminates inwardly in an upwardly and outwardly inclined frusto-conical wall 13. The lower annular portion 14 of the side wall 10 together with the horizontal bottom 12 and the inclined wall 13 defines a lubricant supply reservoir or sump 15 constituting a repository for an ample supply of lubricant which precludes the necessity for frequent servicing or replenishment of lubricant, in the form of a light penetrating oil. A small area of the lower portion 14 of the side wall 10 is apertured as at 16, the material therefrom being struck out to constitute a filling spout 17 adapted to receive the liquid lubricant externally of the body and direct the same into the reservoir 15. This construction is such as to provide for such filling and replenishment with a minimum danger of loss of lubricant or discharge thereof in such manner as to contact material being spun. An important feature of the invention is the ability to replenish lubricant during operation without loss by shutdown time.

For supplying lubricant upwardly from the reservoir to the area inwardly of the upper edge 11 of the body, there is provided a simple flat annular supply wick 2t) vertically positioned and retained against and parallel with the inner wall of the body it by the flat annular spring band 21. It will be understood that the wick 2i may be formed of a single straight length of absorbent fibrous wick material adapted to convey the lubricant by capillary action, and of a length commensurate with the internal diameter of the wall It} so as to fit snugly thereagainst without overlap and with the opposed ends thereof in substantial vertical contact. It will likewise be understood that the spring retaining band 21 is of a length commensurate with the internal diameter of the wick 29. The inherent resiliency of the band 21 maintains the band in expanded position maintaining the wick in vertical position without undue pressure, the ends of the band being in parallel relation without overlap.

As indicated at 22 the lower edge of the band 21 may be provided with notches 22 spaced upwardly from the inner face of the bottom 12 to facilitate the absorption of lubricant by the Wick and the migration thereof upwardly through the wick. Under normal manufacturing methods, the fit of the parts is normally such as to provide adequate seepage of lubricant from the reservoir 15 to the wick without the necessity for a special construction or spacings or apertures for lubricant admission to the wick 20. The upper edge 23 of the wick extends for the major part of its circumference slightly above the upper edge 24 of the retaining band 21. Such edge is,

however, reduced at diametrically opposite points by eloni gate notches 25 which receive therein the outer ends 25 of transverse inwardly extending secondary feeder wicks 27 receiving lubricant from the supply wick 20. The inner ends 28 of feeder wicks 27 are in contact with and deliver lubricant to an annular generally vertical discharge wick 29. In the flow of lubricant which, as stated, is preferably a light penetrating oil, the lubricant is elevated by capillary action from the reservoir 15 through the vertical supply wick 2t and inwardly through the horizontal secondary feeder wicks 27 to the vertical discharge wick 29 from which it passes to the traveler 30. From the traveler 30 excess lubricant will be spun automatically by centrifugal force to return to the reservoir 15 in the man ner hereinafter further discussed.

As above noted, the upper edge 23 of the vertical supply wick 20 terminates below the upper open end 11 of the body 10 and there is fitted within the upper edge 11 above the top edge of the wick 24 a discharge wick support. This support comprises upper and lower Wick supports, the lower support including an annular peripheral flange 31 the outer edge of which is of diameter commensurate with the internal diameter of the upper edge 11 so as to provide for a snug fit of the flange therein without requiring special tools or methods for assembly or securing means. A frictional contact suffices to maintain the parts in assembled relation. Detents 32, however, are struck inwardly at desired spacing about the edge 11 to provide a rest for the edge of the flange 31 to preclude the inadvertent inward movement of the flange beyond the desired horizontal disposition thereof. At the inner circumference of the flange 31, there is formed a downwardly extending flange 35 terminating at its lower end in a return bent U portion 36 and upwardly and slightly inwardly therefrom extends the companion flange 37, the

flanges

35 and 37 constituting a U-shaped receiving pocket for the lower portion 38 of the annular discharge wick 29.

In cooperation with the lower discharge wick support, there is provided a somewhat similar but inverted U upper discharge wick support including a peripheral horizontal flange 40, the outer edge 41 of which registers with the outer edge of the lower support which is received therewith by frictional fit within the upper edge 11 of the body 10. The inner edge of the flange is formed with an upstanding annular flange 42 terminating with an upper inverted U bend 43 merging into an inwardly inclined upper wall surface 44 which terminates in a downwardly extending vertical terminal wall 45. It will be seen that the generally inverted U formation formed by the walls of the upper support provide a receiving annulus for the upper edge 46 of the generally vertical annular discharge wick 29. Thus, in cooperation with the U-shaped formation of the return bend of the lower discharge wick supporting member, an adequate mounting for both the upper and lower edges of the discharge wick is provided, leaving an open space 59 therebetween at which area the inner face of the discharge wick is exposed. It will be noted, however, that the inward inclination of the inner wall 37 of the lower discharge wick support is inwardly disposed with respect to the vertical wall of the upper member, and hence the traveler 30 is mounted in such manner as to be free of actual contact with the discharge wick 29 at the exposed area 50. This position of the traveler is indicated in FIG. 2 and acts to insure spacing of the traveler from the wick to prevent friction and charring of the wick. This spacing also insures free air flow to cool the traveler and to permit oil to be drawn to the traveler by such air flow as the traveler passes near the wick at high speed. This spacing of the traveler by the level of the element 45 also insures ample thread room for the passage of thread without contact with the ring.

In the operation of the device, it will be seen that as the lubricant is drawn upwardly from the reservoir 15 by the vertical feed wick 20, it will pass inwardly through the wicks 27 to saturate the discharge wick 29. As the traveler 30 is rotated at high velocity, supported by the combined

walls

42 and 35 of the wick mounting members, such movement will by virtue of its speed create a suction and air movement such as to cause the lubricant to flow by asperation through the space 50 to the traveler whereupon it flows along the inner surface thereof to lubricate the

walls

45 and 37. Since the reservoir will maintain a substantial amount of lubricant adequate for long periods of operation such flow will be maintained without supervision.

It will of course be understood that the flow of lubricant thus established may be in substantial excess of that required to maintain the necessary oil film to reduce friction, and such excess liquid lubricant will pass from the lower end of the traveler outwardly by centrifugal force and by air flow to be thrown against the retaining plate 21 and travel downwardly into the reservoir 15 to establish a recirculation of lubricant. Not only is such recirculation effective in maintaining an adequate supply of lubricant over a long period of operation, but such recirculation provides an economy in lubrication, since excess lubrication which otherwise might be flung from the ring is retained therein for reuse. Such capture of excess lubricant also provides means for inhibiting the discharge of lubricant in such manner as to cause contact with the material being spun and to the detriment thereof.

It will of course be understood that the invention is not confined or limited to specific materials which may be employed, it being understood, however, that suitable metal stampings may be utilized in the construction of the body as well as the upper and lower distributing wick supports. It will be noted that this construction avoids the necessity of threaded securing means or other special attaching elements and that the parts may be readily formed from stampings or in other equally economical manner. The wick elements are preferably formed of felt or like material through which capillary action acts in the conveyance of the lubricating material. It will of course be understood that the invention is not limited or confined to the specific structural details herein enumerated and that numerous changes, modifications and the full use of equivalents may be resorted to in the practice of the invention without departure from the spirit or scope of the appended claims.
