' 8 Claims.

, This invention relates to spinning and twisting rings. When reference hereinafter-ismade :tola spinning ring, it is to be understood-that the expression includes'as well twisting rings.

The invention is particularly concerned with that type of spinning ring made .of powdered metal. Powdered metalrings have recently come into extensive use because-of the-ease with-which they may be kept properly lubricated; thereby to lengthen greatly the life ofthe traveler as it moves at high velocity about the ring.

One of the difficulties encountered =in--the;-.use of powdered metal spinning rings is the .question of feeding oil to the ring at the proper, rate. .The ring and its supporting flange,- beinggporous, absorbsthe oil as received transmitting-it to the entire circumferential surface of the ring "from which it is picked up ,by the traveler. If oil-is received by the ring at too great-a rate, the traveler cannot utilize all that is:availablewith :the result that some of the oil will collect onthe exterior portions of the ring thatare notengaged by the traveler and on these oily .-areas, lint and 'dirt will gather inan objectionable manner.

It hasbeen found that it is :better .to control the rate of oil fedto the spinning ringthanto vary the structure of the ring itself to make it more or less absorbent. In other wordsyit is better to'havea ring of standardabsorptive capacity-and then feed oil to it at the appropriate rate. to'meet the'required lubrication conditions.

-Accordingly, it .is an object of this invention. to provide means which may be used-with-conventional individual spinning rings and their holders which will result inthe oil being transferred to the ring proper at-whatever rate, is required. The invention: is such that if the .rate' of oil feeding is found to be too high, modification of. the meter- 'ing means may :be made to decrease .the rate of absorption and conversely, if .the rate of feed is found to be too low to provide proper lubrication, the metering means again. may: bevaried so that the rate of absorption maybe increased.

, Another object of the, inventioneisto .provide a spinning ring oil supplying.- mechanism havinga reservoir. in which a supply of oil may be .placed sufficient to last for a substantialcperiod of time the oil being transmitteditothe rings-at: a-;sloW metered rate.

A further object of the invention is to provide :a construction for 'feecling oil at ametered rate to either the horizontal type of spinning ring, or the vertical type. That :is t'ozsay,rtheYbasestructure which. support the: spinningring .an'd the metering mechanism can be made-isubstantially 2 identical regardless of the particular type of rin that is-attac'hed, thereto.

These and. other objects of the invention will become .moreapparent as the description proceeds with the aid of the accompanying drawings, in which Fig. 1 is a plan view of a spinning ring mounted on a holder which incorporates the invention.

Fig. 2 is a vertical section on the line 22 of Fig. 1.

Fig. 3 is aplan view of the spinning ring holder similar tothat shown in Fig. l, but from which the spinning ring has been removed.

Fig. 4 is a planview of the spinning ring holder similar to Fig. 3, but from which the wick'supporting separator has been removed.

Fig. -5' is a fragmentary plan view of the front half of a spinning ring holder similar to that shown in Fig. 3, but with the width-of the channel reduced at the front'thereof tofacilitate piecing up by the operator.

Fig. 6 is a vertical sectional view similar to Fig. 2, but showing the invention in use with a vertical type spinning ring rather than the horizontal type of Fig. 2.

Fig. 7 is an enlarged fragmentary plan view of the ends of the wick carrying separator.

Fig. 8 "is a side elevation on the line 8-8 of Fig. 1 showing in enlarged detail the metering mechanism and ring.

Referring to Fig. 1, there is shown a ring rail .2 on which is mounted in a conventional manner a spinning ring holder 4. This holder has typical feed 6 andtenabling the ring to be secured to the railby the screws [0 and I2.

As can be, seen in Fig. 2, which is a vertical section taken on the line 2-4 of Fig. l, the holder 4 includes a circular channel or moat l4 about the bottom of which oil flows as itLmay be received from the reservoir 16 which has a passage I 8 leading therefrom into the channel l4.

Extending about the channel M as shown in Fig. 4 are aplurality of staggered lugs 20 which 'act to support a wick carrying separator 22 which can be seen in Figs. 2 and 3. This separator is not continuous, but is broken with its ends at 24 and 26. As can be seen in Figs. 2, 3, 4, and 8, the metering meansconsists of a short length of felt 28 with :itsrends atSll and 32 positioned in the channel M where it will underlie the end portions of separator 22. The length and :density-of this metering felt may be varied to give it greater or less oil absorbing and transmitting capacity.

.1'Ihe1upper'surface of separator 22 has a depres- .sion;34 in iwhich-is laid; for, the;=entire circumference thereof a wick 36 preferably made of fine filaments of glass, braided together to form what is known as a glass wick. Glass wicks are commercially available and use is made thereof because they constitute the most suitable type of wick now known.

The two ends 24 and 26 of separator 22 are notched as at 38 and 40 in Figs. 7 and 8. These notches are helpful in maintaining wick 36 in position in depression 34 as the unit is being assembled and assist in holding the ends 32 and M of wick 36 as shown in Fig. 8 in proper position against the metering felt 28.

After the separator 22 and the wick 36 mounted thereon have been assembled to the position shown in Fig. 3 with separator 22 supported by lugs 20 and with the wick ends 52 and 44 resting on the metering felt 28, the spinning ring proper may then be inserted in the holder. This arrangement is shown in Fig. 2 in which the oil receiving flange 45 of the ring 41 is of such vertical dimension that when the shoulder 4-8 is resting on the upper edge 50 of the inner wall 52 of the channel M, the bottom 54 of flange 46 will rest on top of and make good contact with wick 36 about the latters entire circumference with the exception of the short section between the ends 24 and 26 of separator 22. This short omission, however, is insufficient to cause any adverse eifect to the oil transmission. The ring 41 is secured to the holder by screws 55.

With the unit assembled in the manner just described, oil is then placed in reservoir it from which it flows through passage 18 and around the bottom of the channel It. In due course, the oil reaches and saturates metering felt 28, which is positioned approximately 180 from the passage it so that oil will reach it simultaneously from both sides.

Metering felt 28 now saturated with oil then begins to transmit the oil to the ends t2 and 44 of wick 36 with the result that the oil is then carried about the entire circumference of the wick as it rests in the shallow channel 34 of the upper side of separator 22. Inasmuch as the bottom of flange 46 is resting on wick 36, it is obvious that oil will in this way begin to be transferred to the underside of flange 46, thence, oil will move upwardly through the vertical rib 56 into ring 41. about its entire circumference by wick 36, it will be understood that the absorbed oil will arrive at all parts of ring M substantially simultaneously. Feeding that occurs thereafter will likewise be uniform so that the traveler 60 will be properly lubricated at all portions of the ring 41 as it moves thereabout.

The above described construction has the great advantage that the rate at which ring 4'! receives oil may be varied at will. In the first place, the metering felt may be changed to more or less absorbent material so that the rate of feed to the wick ends 42 and 44 may be varied. Again, the size and character of wick 35 may be varied so that the under side of flange 46 will be presented with more or less oil as conditions require. In other words, the surface contact between wick 36 and the under side 54 of flange "it may be changed and thus the total amount of oil entering the ring 58 may be directly controlled. In this way, if it is found that the traveler 6D is receiving too much or too little oil, the wicks may be shifted to correct the condition. When the proper balance is reached, no fur- Since oil is being fed to flange at ther attention to the oiling system is required,

except the occasional addition of oil to reservoir l6.

It should be noted that the inner and outer perimeters of separator 22 make a very close fit with the inner and outer walls of channel Hi. Thus, even though the space between the under side of separator 22 and the bottom of channel M is completely filled with oil, no oil will be received by wick 36 except that which is introduced from metering felt 28 to the wick ends 42 and 44. Accordingly, with the reservoir available for oil storage plus the substantial circumferential space beneath the separator 22, there is available enough oil to last for an extended period.

The construction shown in Fig. 6 with respect to the metered oil transferring characteristics of the invention is the same as that shown in Fig. 2. The difierence, however, resides in the fact that the ring 4'! has been replaced by a vertical type ring 60, which is connected to the flange 46 in the manner shown. This has necessitated shortening the vertical dimension of the inner wall 62 of the channel, but does not affect the construction of the oil separator 22, the metering felt 28 or the wick 36.

The construction illustrated in Fig. 5 is included to show that the invention may be used with equal facility with that type of ring and holder in which the oil channel is narrowed in front so that the operator may get his finger in closer under the outer portion of ring 41 when piecing-up. In this construction, the separator 22 is cut away along its outer edge at the appropriate place to fit within the narrowed channel between the inner wall 6t and outer wall iii: of the holder. This change in form does not, however, affect transfer of oil to the bottom of the ring flange it; for the wick 3G is continuous about the holder base the same as in Fig. 3.

The term metering felt as used herein is not to be construed as limiting the metering mechanism to the use of material made of animal fibers; rather the term is intended to mean any suitable material capable of acting in the manner described so as to absorb oil in the channel and to transmit the oil to the wick which is in contact therewith.

It is my intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosures which do not constitute departures from the spirit and scope of the invention.
