LEAKAGE-PREVENTING CONSTRUCTION FOR SPINNING RINGS It is consequently an object of this invention to provide an improved structure to prevent leakage of lubricant in passing to a spinning ring from a support therefor, and to which lubricant may be supplied from difierent directions.

In the accompanying drawings:

FIG. 1 is a top plan view of a spinning ring mounted on a support and showing means for supplying lubricant under pressure to the spinning ring.

FIG. 2 is a fragmentary section thereof on an enlarged scale on line 22, FIG. 1.

FIG. 3 is a sectional elevation similar to FIG. 2 showing our improvements applied to a spinning ring of a different construction.

The drawings show in FIG. 1 a spinning ring having an inner ring 11 and a traveller 12 of usual construction which spins in contact with the ring. The ring is lubricated by oil or other lubricant passing into a passage 15 leading to a circular reservoir 16 arranged in the ring between the body portion thereof and the inner ring 11. The inner ring has passages of any suitable type formed between it and the main ring through which passages lubricant can pass to the surface of the inner ring which are contacted by the traveller.

Oil or other lubricant is supplied automatically to the spinning ring from a supporting member 20 which has an inlet passage or cavity 22 connected with a coupling member 23 to which a conduit (not shown) may be connected to bring lubricant from an automatic pumping mechanism of usual construction to the inlet passage 22 of the support.

The ring is supported on the supporting member 20 in any suitable manner, for example, by means of an annular shoulder 18 on the ring which rests on the inner edge of the annular web 24 of the supporting member.

At a part of the web or body portion 24 of the supporting .member a discharge passage 25 is provided extending from the inner edge of the supporting member to the inlet passage or cavity 22. The ring has an inlet opening 27 which terminates at the outer edge of the ring and connects with the passage 15 and the reservoir 16. The ring is so positioned in the supporting member that the passage 25 registers with the passage and opening 27. A tube 26 is provided which connects these two passages. This tube is driven into the passage 25 from the inner end of this passage and the tool (not shown) which drives the tube 26 into the passage 25 has an outer circular portion of larger diameter than that of the tube 26 so that this part of larger diameter engages a part of the end of the web 24 and peins the same over to form a tight engagement with the discharge tube 26 to prevent leakage of lubricant about the exterior of the tube 26. The inner end of the tube 26 may, if desired, be cut at an angle to the length so as to ensure passage of lubricant from this tube into the passage 15.

The inner end of the tube 26 is also of such size as to form a drive fit with the inlet opening 27 of the ring. The assembly of the ring on the supporting member is effected by holding the ring 10 at a slight angle to the supporting member with the end of the tube 26 extending into the inlet opening 27 of the ring, whereupon the ring is swung into its normal position concentric with the body portion 24 of the supporting member.

By peening the metal of the end of the web 24 against the tube 26 a tight seal is formed about the tube and a recess or depression 28 is also formed in the web which serves to receive a sealant and from which the sealant may readily flow to seal the connection between the ring and the supporting member as well as between the tube 26 and both the ring and the supporting member.

In the modified construction shown in FIG. 3, the supporting member 40 is identical with that shown in FIGS. 1 and 2, being provided with a main lubricant passage 42 which is arranged at an angle to the connecting passage 45 containing the tube 46. A liquidtight connection is made by peening the metal of the inner face of the web 44 against the tube 46. This peening provides a recess or depression 48 which forms a reservoir for a sealing medium, which not only seals the tube 46 into liquidtight connection with the ring 49 and the supporting member, but also seals the ring to its supporting member. In this construction the ring has a passage 50 through which lubricant is conducted to the inner surface of the ring, which surface is contacted by the traveller.

By means of the construction described the machining to form the lubricant passage 45 is not only facilitated but also the passage 42 is not employed for the entry of drilling or other tools to form the connecting lubricant passage 45. Consequently the passage 22 is accessible from various points of the supporting member so that the connections 23 for a lubricant coupling device may be formed from above, below, at I side or bottom of the supporting member whereby the ring construction may be employed on spinning machines of different types.

It will be understood that various changes in the details, materials and arrangements of parts which have been herein described and illustrated in order to explain the nature of the invention may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.

I claim:

1. A spinning ring assembly comprising a spinning ring support, a first lubricant passage in said support, a first surface on said support proximate said first lubricant passage, a spinning ring, a second lubricant passage in said spinning ring, a second surface on said spinning ring proximate said second lubricant passage, said first and second surfaces being in abutting relationship when said spinning ring is mounted on said support, a tube extending between said first and second lubricant passages and having a central portion proximate said first and second surfaces when said spinning ring is mounted on said support, and a sealant-receiving depression proximate said first and second surfaces and adjacent said central portion of said tube for receiving sealant to provide a seal about said central portion of said tube and between said spinning ring and said spinning ring support.

2. A spinning ring assembly as set forth in claim I wherein said first passage has an outlet and said second passage has an inlet proximate said outlet, and wherein said tube is driven into said outlet of said first lubricant passage with a drive fit.

3. A spinning ring assembly as set forth in claim 2 wherein said depression is located in said spinning ring support.

4. A spinning ring assembly as set forth in claim I wherein said first lubricant passage comprises a first portion which receives said tube, and a second portion which extends at an angle to said first portion.

Claims

2. A spinning ring assembly as set forth in claim 1 wherein said first passage has an outlet and said second passage has an inlet proximate said outlet, and wherein said tube is driven into said outlet of said first lubricant passage with a drive fit.

4. A spinning ring assembly as set forth in claim 1 wherein said first lubricant passage comprises a first portion which receives said tube, and a second portion which extends at an angle to said first portion.
