TWISTER-RING LUBRICATOR.

Application filed May 20, 1924. Serial No. 714,672.

Twister-Ring Lubricators, of which the fol lowing is a specification.

The invention relates to spinning and twisting machines of the character used in the textile industry, and more particularly to apparatus for lubricating the rings of spinning and twisting machines of thering type. The invention will be herein disclosed as embodied in a ring twister, it being un-- derstood, however, that it may also be used in ring spinning frames, and that the term twisting machine or twister, as herein used, is intended to include ring spinning mechanisms.

In my prior Patents Nos. 1,466,004: and 1,466,005 I have disclosed arrangements for automatically lubricatin twister rings, these mechanisms being designed to eliminate the necessity for manually applying lubricating material to the rings, as is now the common practice. In actual use these mechanisms have proved to be highly advantageous, permitting a material increase in the speed of operation of the machines,

lengthening the life of the travellers, and producing a more even and uniform'tension on the yarn.

The present invention aims to further improve and perfect lubricating apparatus of this type, particularly with a view to reducing' the manufacturing expense and facilitatmg the application of such apparatus to machines already in use. I

The nature of the invention will be readily understood from the following description when read' in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

Referring now to the drawings,

F1gure 1 is a perspective view of part of a ring rail equipped with lubricating apparatus embodying this invention;

Fig. 2 is a longitudinal, vertical, crosssectional view through the adjacent edges of the rings shown in Fig. 1 and the parts between them; and

Fig. 3 is a cross-sectional view on the line 33, Fig. 1.

The drawings show a ring rail 2 supporting two rings 3r3, each'carrying a traveller 4. These parts are constructed, arranged and operated in the usual manner.

The lubricating apparatus shown comprises an oil well or reservoir 5 which may conveniently be made of sheet metal and is removably secured to the lower side of the rail 2 by means of bolts 66. This well is located between the rings 33, as clearly shown in the drawings. Oil is conducted from the well 5 to the inner surfaces of the rings 33 by capillary feeders 7-7, these feeders being located in slots formed partly .in the rings and partly in the rail 2, as best shown in Fig.2. The feeders are made of felt, wood, or any suitable material. It will be observed that they are inclined so that they must lift the oil.

The slots preferably are formed by mill ing with a circular flat milling cutter so that when the cutter breaks through into the inner surface of the ring it will form a curved opening, as clearly shown at 8 in Figs. 1 and 3. It should be noted that when the traveller is running it stands in the po- 'sition shown in 2, and only the "port-ions t-heredf at the knee 9 and the bottom bend 9' bear agaiilst the ring 3. The width of the bearing area of the ring which is engaged by the knee of the traveller lies ap-' proximately between the dotted lines 10, Fig. 3. It will be observed that the slot 8 cuts into this area but does not interrupt it, and that the exposed end of the feeder lies substantially flush with the inner surface of the ring. This location of. the slot 8 with' reference to the bearing area engaged by the ring, avoids any interruption of the bearing surface on which the traveller runs, and therefore eliminates any shock or variation in the bearing contact of the traveller with the ring. At the same time, it enables the traveller to wipe oil from the exposed surface of the feeder as it passes across the slot and while it still maintains its bearing on the metal surface of the ring. This arrangement thus prevents the cutting of either the oil feeder or the edges of the slot by the traveller.

The fact that the upper end of the slot 8.

drilled in the rail 2 and carries a spring feeders in normally closes the upper end of the tube. The supply of oil in the reservoir may therefore be replenished with the aid of an ordinary oil can, the ball being depressed with the end of the spout of the can during the replenishing operation.

It will be evident from the foregoing that this invention provides lubricating apparatus which can be applied very economically to twister rails already in use, it being a simple matter to mill the slots required for the capillary feeders 7 and to fit these placewith the well 5 and filling tube 12. Preferably, an oil well is located between each pair of rings, as shown, but, if desired, a long oil .well may be placed under one edge of the rail, a single well supplying oil 1for the entire set of rings mounted in the rai While I have herein shown and described the best embodiment of my inventionthat I have so far devised, it will be understood pressed ball 14 that that the invention is not limited to the exact details of the construction shown.

Having thus described my invention, what I desire to claim as new is:

1. In a ring twister, the combination of a pair of rings, a rail in which said rings are mounted, a traveller for each ring, an oil well mounted between said rings, for feeding oilfrom said well to both of said rings.

2. In a ring twister, the combination of a plurality of rings, a ringrail in which said rings are mounted, a traveller for each ring, an oil well removably secured to the lower side of said rail, and means for feeding oil from said well to said rings.

3. In a ring twister, the combination of a plurality of ,rmgs, a ring rail in which said rings are mounted, a traveller for each ring, an oil well removably secured to the lower side of said rail, and capillary feeders for conducting oil from said well to the inner surfaces of said rings.

4. In a ring twister, the combination of a ring, a traveller mounted thereon, an oil K well, and a capillary feeder for conducting oil from said well to said ring, said ringhaving a slot in which said feeder is located, said slot opening into the inner surface of said ring and being inclined with reference to the path of said traveller.

and means 5; In a ring twister, the combination of a ring, a traveller mounted thereon, an oil well, said ring having a slot opening into its inner surface, and a capillary feeder located in said slot and operative to conduct oil from said well to said ring, said feeder having its inner end substantially flush with the inner surface of said ring, and said slot being positioned to avoid any interruption of the bearing surface on which the knee of the traveller runs.

6. In a ring twister, the combination of a ring, a traveller mounted thereon, an oil well, said ring having a slot opening into its inner surface, and a capillary feeder located in said slot and operative to conduct oil from said well to said ring, said ring having a continuous surface to support the knee of said traveller as the traveller revolves, which surface is cut into but not interrupted by said slot, and the inner end of said feeder being located substantially flush with the inner surface of said ring, whereby the traveller is operative to wipe oil from said feeder while still maintaining its bearing on thesurface of the ring closelyadjacent to the feeder.

7. In a ring .twister,'the combination of a ring rail, a ring mounted in said rail, a traveller supported on said ring, an oil well removably secured to the lower side of said rail at one side of said ring, said ring having an inclined slot leading downwardly from its inner surface toward said well, and a capillary feeder located in said slot 'and operative to conduct oil from said well to the inner surface of said ring, the inner end of said slot being curved.-

8. In a ring twister, the combination of a plurality of rings, a ring rail in which said rings are mounted,-a traveller for each ring, an oil well removably secured to the lower side of said rail, each of said rings having an inclined slot leading from the inner surface thereof downwardly toward said well, and a capillary feeder located in each of sa 1d slots and operative to conduct oil from said well to the inner surface of its respective ring, the inner end of each slot being curved and opening into the bearing area for the knee of the traveller without interrupting
