12 Claims. (Cl. 118-595) My invention relates to rings and travelers for spinning and twisting frames.

The principal object of my invention is to provide a ring and traveler for spinning and twisting frames, having means for effectively lubricating the same so that the surface of the ring against which the traveler bears in its movement will at all times be properly lubricated, and wear on the ring and traveler thus reduced to a minimum.

example as any of the alloy steels commonly used for such purpose. This ring may be hardened and polished in the usual manner. The ring III has a base portion l I, of sufllcient area in crosssection to afford the necessary rigidity.

A portion l2 extends upwardly from the base portion ll of the ring Ill, being so shaped as to provide an inner bearing surface l3, which is made frus'to-conical for a purpose to be presently explained.

A further object of my invention is to provide a lubricating ring and traveler which are so constructed and arranged that an ample supply of lubricating oil may be provided, thus avoiding the necessity of constant attention to insure proper lubrication.

A further object of my invention is to provide a ring and traveler construction in which the traveler is provided with means for insuring a large bearing surface at the place where the traveler contacts with the ring in its movement about the ring.

A further object of my invention is to provide an improved form of traveler which will have no tendency to cook and chatter during the opera- A small groove I5 is preferably provided where the upper edge of the bearing surface 13 joins the under surface of the inwardly extending flange It.

An oil reservoir [6, preferably made of pressed shaped as to provide an annular chamber I8,

disposed below the base portion ll of the ring. In this annular chamber l8 there is mounted an annular wick I9, made of felt or other suitable material, which extends upwardly from the bottom of said annular chamber, and terminates at tion. its upper end in an annular lipportion 20, which Afurther object of my invention is to provide a engages the lower part of the inner frustoring and traveler construction by means of which conical bearing surface l3 of the ring I. a more uniform twist in the yarn will be obtained, The inner wall 2| of the oil reservoir'lB exand irregularities in and breakage of the yarn tends upwardly to form a guard, to shield the will be greatly reduced. working surface of the ring l0 against the ac- The nature and characteristic features of my cumulation thereon of the fly and grit which invention will be more readily understood from are thrown centrifugally outwardly during the the following description, taken in connection spinning and twisting operation.

The traveler is also provided with ring, made of any preferred material, such for a portion 24 extending outwardly over the top of the ring l0, then downwardly on the outside of the ring, as at 25, to prevent the traveler from becoming detached from the ring after it is snapped in place thereon.

The traveler is also provided with a downwardly extending portion 26, which passes below the inwardly extending flange I I of the ring In, and thence extends outwardly, as at 21, where it is secured to a tail piece 28 which bears against the frusto-conical bearing surface l3 of the ring.

The outer surface of the tail piece 28 is shaped complementally to the bearing surface l3 of the ring Ill, thereby affording a bearing surface of considerable area, which serves to reduce the wear on the traveler as well as on the ring.

The tail piece 28 of the traveler is preferably of a peculiar conformation and arrangement. The lower outwardly extending portion 21 of the traveler is secured to the tail piece 28 near one end thereof (see Fig. 3), so that the greater portion of the mass of the tail piece is disposed to one side of the place of engagement of the yarn with the traveler, for a purpose to be presently explained.

Prefer-ably, also, the ends of the tail piece 28 of the traveler are inclined, as at 29 and 30, and the upper corner of the short end of said tail piece is slightly rounded, as at 3|.

The operation of the ring and traveler, as above described, may now be explained. A suitable qu-antity of oil having been placed in the annular chamber l8 of the reservoir it, the same will be fed upwardly by the wick l9 to the lower part of the frusto-conical bearing surface l3 of the ring ID. The oil will then be evenly spread over said bearing surface of the ring, by reason of the agitation of the air caused by the movement of the traveler, and also by reason of the natural creeping characteristic of the oil. However, the top surface of the ring 10 will be main tained free of oil. and there will be no throwout of the oil during the running.

In the manner above described. the frustoconical bearing i3 of the ring l will be efiectively lubricated, and a film of the oil will be maintained over the entire surface of said ring. It is to be noted that during the operation the traveler bears only on the lubricated surface of the ring.

The bearing surface l3 of the ring will be protected from the fly and grit by the vertically extending wall 2| of the oil reservoir I6. This wall 2| will also serve to prevent the loose end of the yarn, which flies outwardly whenever a breakage occurs, from coming in contact with the oil on the bearing surface l3 of the ring In, and becoming fouled thereby.

-As hereinbefore pointed out, the tail piece 28 of the traveler affords a bearing surface of considerable area, and the inclined ends 29 and 30 of said tail piece will aid in distributing the oil more evenly between the bearing surfaces of the tail piece 28 and the ring ill, as well as serving to bring about a more effective agitation of the air adjacent the bearing surface l3 of the ring, for the purpose of assisting in the spreading of the oil thereover.

The purpose of the inclined frusto-conical surface l3 of the ring, and the coasting tail piece 28 of the traveler, may now be explained. The combined effect of the gravitational and centrifugal pull on the mass of the traveler and the tail piece is such as effectively to overcome the force imparted by the yarn, which force tends to raise the traveler and pull the same inwardly.

It will be seen that when the traveler rotates at high speed about the ring It), the inclination of the bearing surface l3 of the ring will tend to cause the traveler to be impelled downwardly against the tension of the yarn, and thereby an effective balance will be obtained, so that in reality but little pressure will be exerted by the traveler against the ring. v

Furthermore, the provision of the unsymmetrically disposed tail piece 28 of the traveler, by reason of the centrifugal force exerted thereon, will maintain the traveler in a radial position notwithstanding the tendency of the yarn to cock the same by reason of the angularity at which the yarn runs off from the traveler to the cop or bobbin. In this manner, the tendency of the traveler to chatter will be eliminated.

It will thus be seen that there is provided a novel form of ring and traveler therefor, which are so constructed and arranged as to insure a proper lubrication of the bearing surfaces, and by means of which fouling of the yarn by the oil will be substantially eliminated, wear will be reduced to a minimum, a more uniform twist will be imparted to the yarn, and breakage of the yarn will be greatly reduced.
