April 15, 1958 J. RABOISSON LUBRICATING ARRANGEMENTS FOR TEXTILE s mumc Rmcs Filed larch 1, 1957 United States Patent LUBRICATING ARRANGEMENTS FOR TEXTILE SPINNING RINGS Joseph Raboisson, Soultz, France, assignor to Manufacture Alsacienne DeBroches, Sonltz, France Application March 1, 1957, Serial No. 643,411

Claims priority, application France March 2, 1956 2 Claims. (Cl. 57-120) This invention relates to lubricating arrangements for textile spinning rings and the like, and more particularly, to such arrangements for lubricating the traveller-engaging finally through a hole 34 located in the same radial plane as the hole 33 and which also leads from the circular groove and opens onto the upper track 23, into a recess 35 which also extends in a circumferential direction. The

5 end of the distributing wick spreads in this latter recess.

bearing faces of such rings of the type with a supply wick arranged in an annular groove of the ring and having at least one end thereof dipping into a lubricant-receiving well applied to the ring, and holes extending from said groove to said faces and containing distributing wicks which extend throughout said holes and have portions thereof in mutual engagement with said supply wick in said annular groove.

through an individual hole opening into a recess of the other bearing face, said wick end spreading into said last mentioned recess.

The invention is illustrated by way of example in the accompanying drawings in which:

Fig. 1 is a vertical section, made on line I-I of Fig. 2 of a ring of a spinning and twisting machine according to the invention, and

Fig. 2 is a horizontal section, made on line HII of Fig. 1.

In the embodiment illustrated, 21 is a ring of a spinning or a twisting machine, having a conical inner track or bearing surface 22 and an upper track or bearing surface 23, for atraveller (not shown). The inner bearing face 22 is flared downwardly and outwardly from a point adjacent the top side of the ring, while the upper track 23 is sloping downwardly and inwardly. The ring carrier 24 comprises a well 25 containing felt impregnated with a lubricant. The supply wick 26, which dips into this well and sucks the oil therefrom by capillarity, extends through the ring carrier 24 through a notch 27, which might be replaced, however, by a common hole or two individual holes, and it runs round the ring in the circular groove 28.

Distributing wicks 29, two in number in the embodiment illustrated, are also accommodated in the groove 28, in contact with the supply wick all along their common path in the groove.

Each of the end portions of each distributing wick 29 passes, first, through a hole 31 which opens onto the inner track into a recess 32 which extends on either side of the hole in a circumferential direction, then through a hole 33 located quite near the hole 31, which brings the end portion of the wick back into the circular groove, and

It may be said, therefore, that the end portions of the distributing wicks are laced through both holes 31 and 33. In the embodiment illustrated, the extreme portions of each wick are threaded into the extreme holes of two adjacent pairs of holes, so that the wicks do not run back along themselves. 3

It will be seen that this disposition affords a very easy mounting and threading of thewicks; therefore they may be readily replaced as soon as they are soiled.

No member is necessary for maintaining the wicks, the latter are in a slightly retracted relation in the recesses and cannot get caught accidentally, mainly by the moving traveller. Furthermore, a perfect distribution of the oil is always provided, by virtue of the distribution of the distributing wicks fed by the common supply wick. No interruption may occur in the supply of lubricant to the tracks resulting from drying and hardening of the wicks due to ventilation, because the supply wick is enclosed within the circular groove and sheltered against any air draught. It forms, therein, a sort of bridge between the two holes in which the distributing wick passes toward the inner track, thus ensuring the oil transfer beyond said holes, toward the next. Furthermore, the flow of lubricant therein is not excessive, because the wicks are not exposed endwise, and the number of fibers which come into contact with the traveller is very small.

As regards the upper track to which the ends of the distributing wicks reach, the oil which is'brought thereto is not integrally scraped by the traveller; it may be left stored in the circumferential recesses of the track.

The wicks cannot get squeezed or tom-up by the traveller in the course of its rotational movement, since they are housed within the recesses of both tracks; a long time .service, therefore, is ensured.

Finally, since the housings for the wicks in both tracks do not form a continuous furrow, there is no risk for a shoulder to be formed on the traveller branches, due to wear thereof.

As many changes could be made in the above construction and many widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description, or shown in the accompanying drawings, shall be interpreted as illustrative, and not in a limiting sense.

What I claim is:

1. A spinning ring for a traveller having an inner and an upper traveller-engaging bearing face, an annular groove in the outer peripheral face of said ring, a number of pairs of twin holes extending through said ring from said annular groove into a corresponding number of recesses in one of said bearing faces, a corresponding number of individual holes also extending through said ring from said annular groove into the other of said bearing faces, a lubricant well applied to the ring, a single supply wick arranged entirely around said ring in said annular groove thereof and having at least one end thereof dipping into said lubricant well, and lubricant distributing wicks also positioned in said groove in close lubricant conducting relation with said supply wick and each having each end portion thereof extending through one pair of said twin holes successively toward and away from the corresponding bearing face, and through one of said individual holes, said end portion spreading into the corresponding recess of said other bearing face, each of said. holes, individual holes being located substantially in the same 5 radial plane as the hole of the corresponding pair of twin holes which contains the portion of the corresponding distributing wick nearer the end thereof. 1,899,635

2. A spinning ring according to claim 1, wherein the 1,986,910 holes of two pairs of said twin holes which contain the 10 2,435,939

extreme portions of any given distributing wick are located at a distance from each other greater than the distance between the other holes of said pairs of twin References Cited in the file of this patent UNITED STATES PATENTS
