WICKLESS VERTICAL TYPE SPINNING RING OF POROUS METAL Filed Oct. 22, 1965 Iva/126322202 15.- J03??? T. O'ComaeZZ, flndflew J: Wuysou, by 1+ W4 LHEZoflaaeys United States Patent WICKLESS VERTICAL TYPE SPINNING RING OF POROUS METAL Andrew J. Wayson, Needham, and John T. OConnell,
Medfield, Mass, assignors to Merriman, Inc., a corporation of Massachusetts Filed Oct. 22, 1965, Ser. No. 500,533 6 Claims. (Cl. 57120) This invention relates to the textile industry and is particularly concerned with spinning and twisting rings made of porous material such as pressed sintered powdered metal. When the term spinning ring is used hereinafter, it will be understood to include the use of such rings in twisting operations.
The use of spinning rings made of powdered metal is now Well understood in the industry. These rings provide ready means for placing a thin film of oil on all of the surfaces thereof that may be in engagement with the cooperating traveler.
One of the problems that has always been present in the field of porous spinning rings is that of supplying an adequate quantity of the lubricant, ordinarily oil, to an interior area or areas in such manner that the oil will be uniformly transmitted to all of the exterior surfaces. The conventional means of supplying oil to a vertical type ring has been by means of a wick leading from an oil source to a ring encompassing groove. The oil, by capillary action, moves about the wick and is transferred from the wick to the wall of the groove whence it passes through the porous ring to the outer surfaces.
The present invention has as an object the simplification of the oil transmission mechanism from the oil source to the ring. It wil be understood that the oil source may be of any conventional type such as an individual supply for each ring or a common oil line feeding a plurality of rings through suitable taps.
Another object of the invention is to provide a ring of simplified construction which will require a minimum of machining operations following its initial formation in the molding process.
These and other objects of the invention will become more apparent as the description proceeds with the aid of the accompanying drawings in which:
FIG. 1 is a plan view of a spinning ring and oil connection therefor but broken away in part for illustrative purposes; and
FIG. 2 is an enlarged vertical section taken on the line 22 of FIG. 1.
Generally speaking, the inventive concept herein includes the formation of a vertical type spinning ring of conventional dimensions, having therein a narrow vertical deep groove extending continuously about the ring. Oil may be delivered to the groove through a laterally extending passageway. The top of the groove which terminates at the top of the ring is preferably closed in any convenient manner either by a continuous annular ring of metal or other oil impervious material or it may be sealed by the application of a suitable sealing compound.
Referring to FIG. 1, the vertical type spinning ring is indicated at 2. This ring may be of any conventional cross-section and dimensions in accord with normal practices in the trade. The ring has a deep groove 4 which extends continuously about the interior of the ring. The groove starts at the top of the ring and terminates close to the bottom as indicated at 6 in FIG, 2. This groove 4 may be introduced when the ring is initially molded or, if desired, it might be formed after molding by a suitable machining operation. The object in having this deep groove is to present a large surface area in the form of the vertical walls 8 and 10 which will speed the rate at which oil may be absorbed into the body of the ring.
'ings 24. This is all conventional 3,293,841 Patented Dec. 27, 1966 "ice In order to mount the ring on the ring rail 12, a split holder 14 is provided. This holder, upon removal of the screw 16, may be spread apart at the split 17 so that the ring may be introduced into or removed from the holder. The inner periphery of the holder indicated at 18 in FIG. 2 cooperates with a circumferential groove 20 that extends about the outer. circumference of the ring. The particular dimensions of the holder and cooperating groove in the ring are not critical. Preferably, however, the holder, which is of non-porous material, should fit closely within groove 20 so as to minimize oil leakage at the joint.
The holder will conventionally have ears 22 which will rest on and be secured to the ring rail 12 by screw fastenand need not be described in further detail.
At one side of the holder 14 there may be an extension 26 having therein a bore 28 which is in series with passageway 29 through the wall of ring 2 leading to the vertical groove 4. Bore 28 in turn may be connected with a T 30 connecting with a common oil line 32. Thus oil being fed under pressure through oil line 32 will flow through passages 30, 28 and 29 into groove 4. When groove 4 is completely filled, as will be the case because of the pressure in the oil line, the oil will engage all of the wall surfaces 6, 8 and 10 of groove 4.
Groove 4 is closed at its top by an annular cover 34, preferably of metal, which will fit into the rabbeted recess 36, making tight engagement therewith. The cover 34 may be replaced by any type of suitable sealing material of an oil impervious character.
. It will be understood that, while the cover plate 34 is shown at the top of the ring, it could equally well be at the bottom with the groove extending upwardly instead of downwardly. It will also be appreciated that the traveler in operation on a spinning ring does not engage the top surface of the ring at the position of the cover plate, and hence the lack of lubrication on the cover plate is not in the least detrimental to the traveler operation.
The construction heretofore described makes it possible for oil to be introduced in a manner to engage simultaneously a very large interior surface area. This permits quick and uniform absorption of the oil so that it is transmitted rapidly to the exposed ring surfaces. The rate of oil transmission through the ring may, in accord with known procedures, be varied by changing the viscosity of the oil or the porosity of the ring.
The use of the deep oil groove herein described eliminates the necessity of a wick and the corresponding extra groove that must be turned in the exterior of the ring to receive such wick. In the present case, the only machining that must be done on the ring is that of forming the shallow exterior groove into which the holder fits.
It is also appreciated that the ring might be formed with an exterior flange extending around its outer periphery, which flange might rest on a cooperating holder. However, whether the ring is supported by a holder in the manner shown or by an exterior flange resting on a holder the effectiveness of the deep oil groove remains unchanged.
It is intended to cover all changes and modifications of the examples of the invention herein chosen for purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.
We claim:

A vertical type spinning ring made of porous metal, said ring having upper and lower end surfaces, said ring having a deep cylindrical groove extending thereabout, said groove running from one end surface of the ring to an interior position close to the other end of the ring, means closing the open end of said groove, a passageway leading into said groove through the outer side of said ring where- 'by a lubricant can be introduced into said ring under presvtransmission to said exposed outer vertical wall surfaces will be substantially uniform.
