corporation of Massachusetts Application March 5, 1934, Serial No. 714,057
This invention relates to 2 Claims.
a vertical flange type 'of twister ring used particularly for the twisting of heavy yarn,
such as carpet yarn.
In such twisting machines the yarn is guided to the spool or bobbin which is mounted onthe twister ring and which has a very thereto. It has been found that lubrication ing movement relative through a metal traveler vertical flange of a rapid slidof the will greatly prolong the life of the traveler on heavy duty twister rings and will also permit a It is the general object of my present invention to improve the construction cf heavy duty twister rings in such tive lubrication may With this general object manner be provided.
that more effecin view, I have developed certain novel combinations of structural features, which will be hereinafter described and more particularly pointed out in the, ap-
pended claims.
Through the cooperative action of these different features in the disclosed combinations, greatly improved cation are attained.

Preferred forms of my invention'are shown in the drawing, in which Fig. l is a sectional side elevation of a twister ring and associated parts;
Fig. 2 is an enlarged partial sectional elevation, taken along the line 2-2 Fig. 3 is a detail direction of the arrow plan in Fi 1;v

Referring to Figs. twister ring ed in an opening in a ring with a traveler T through which;
1 to In of the vertical flange type mount- 3, I have shown a rail II and provided theyarn Y A suitable th'read' Y may be mounted above differs from the usual three important features.
ring rail l l which communic A wick W is threaded through the openings 2| and the segmental recess 20, and the ends of the provision of 'ily to the extreme bottom the wick extend into the oil pocket 22 and'are preferably coiled therein.
The recess 20 is located in the ring ill at a point above the area of bearing contact of the traveler on the ring when the traveler is in normal running position. Consequently oil is conducted by the wick W directly to theinner upper surface of the ring above the area of traveler engagement, and is conducted indirectly only to the traveler T. As the ring becomes heated 10 during the twisting operation, the oil or lubricant becomes correspondingly thinner and flows down over the inner surface of the ring In, thus effectively lubricating the traveler.
A second feature of my invention comprises 15 a shallow oil groove 30 extending circumferentially around the inner surface of the ring and well within the area of bearing contact of the traveler. This circumferential oil groove cooperates with the segmental 20 recess 20 to provide more effective distribution of the oil delivered by the wick W.
It will be noted, however, that the oil groove 3|! is relatively shallow, so that no substantial amount of oil can accumulate therein. Conse- 25 quently when the yarn breaks and the broken end on the bobbin whips around inside of the ring, no substantial amount of oil will be wiped from the groove 30 to soilthe yarn on the bobbin I or to fly outward onto adjacent bobbins, as would 30 be the case if a deep oil groove were provided.
The third important feature combined in my invention is the provision of a relieved lower inner edge portion for the ring l0, as indicated at 40 in Fig. 2. By cutting away the bottom edge portion of the ring and'providing a convex relieved inner surface, the contact area between the traveler and the ring is reduced, and furthermore the oil or lubricant flows more readedge of the ring than 40 is the case where the traveler engages the whole lower portion of the inner face of the ring. Consequently the bottom edge of the ring is more effectively lubricated, and it is at this point that travelers always burn and break and that lubrica- 45 tion is most essential.
The lower part of the usual traveler T has a substantially straight portion, as'indicated at 4| in Fig. 2,. and this straight portion cannot engage the relieved area or cut-away portion 40 in any 50 normal position of the traveler. I
By the provision of the segmental recess 20, the shallow oil groove 30 and the-lower flange relieved as at 40, I attain extremely effective ring lubrications and am able to run the spindles at 55' I the inner face of 35 substantially higher speeds while at the same time reducing traveler breakage.
- In Fig. 4, I have shown a slight modification in which the segmental recess 20 and relieved portion 40 are retained, but the oil groove 30 is omitted. While this construction does not possess all of the advantages of the construction shown in Fig. 2, it nevertheless provides reasonably effective lubrication and travelers used on this type of ring last for substantially increased periods, particularly on the lighter types of work.
I may also use the segmental recess and circumferential oil groove to advantage in a ring in which the lower edge portion is of normal section, as shown in Fig. 5.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims but what I claim is:
1. A twister ring having a vertical traveler flange provided with a substantially cylindrical inner surface in its upper portion and with an outwardly relieved convex inner surface in its lower portion, said ring having a short oil feed recess in its upper inner surface, an oil wick for said recess, means to supply oil to said wick, and a traveler, said traveler engaging only thelower edge of said ring and a portion of the cylindrical surface of said ring below said 011 feed recess when in operation and clearing said relieved surface, and said wick delivering oil directly to the inner upper surface of said ring above the area of bearing engagement of the traveler on said ring, whereby oil is fed indirectly only to said traveler.
2. A twister ring having a vertical traveler flange provided with a substantially cylindrical inner surface in its upper portion and with an outwardly relieved convex inner surface in its lower portion said ring having a short oil feed recess in its upper inner surface, an oil wick for said recess, means to supply oil to said wick, and a traveler, said traveler engaging only the lower edge of said ring and a portion of the cylindrical surface of said ring below said oil feed recess when in operation and clearing said relieved surface, and said wick delivering oil directly to the inner upper surface of said ring above the area of bearing engagement of the traveler on said ring, whereby oil is fed indirectly only to said traveler, and said ring having a very small shallow circumferential oil groove in the inner surface of said ring positioned within the area of traveler engagement with said ring and substantially below said oll feed recess.
