Patented May 12, 1942 SELF-LUBRICATING SPINNING RING Charles Fillinger, Buffalo, N. Y., assignor to Herr Manufacturing Company, Inc., Buffalo, N. Y.,

a corporation of New York Application May 23, 1341, Serial No. 394,810

1 Claim.

This invention relates to spinning rings and particularly-to the lubrication of such rings.

It has for one of its objects to provide' the ring with self-contained means for feeding at all times a constant flow of lubricant to the bearing faces of the ring to elect maximum lubrication with a minimum of oil consumption.

Another object of the invention is to provide a simple and eflicient lubricating means for spinning means embodying a novel wick structure for delivering the lubricant to the bearing faces of the ring and wherein such wick is of a pre-set density to regulate the amount of lubricant fed to such bearing faces.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claim.

In the accompanyingdrawing:

Figure l is a side elevation of a traverse bar and bobbin showing my improved ring associated therewith. Figure 2 is an enlarged top plan view of the ring in place on the ring holder. Figure 3 is an enlarged fragmentary cross section taken on line 3 3, Figure 2. Figure 4 is a fragmentary cross section on a still larger scale of the lubricating elements of the ring. Figure 5 is an enlarged fragmentary sectional elevation of the wick element. Figure 6 is a perspective View of the wick-retaining and well cover plate.

Similar characters of reference indicate corresponding parts throughout the several views.

Referring now to the drawing, Ill indicates the take-up spool of a spinning machine and traversing the same for reciprocation axially thereof is the usual traverse bar I I upon which a holder I2 is mounted for detachably receiving a spinning ring I3 upon which the traveler I4 revolves,.

this ring embodying the novel means hereinafter described for effectually lubricating it.

The holder I2 is substantially annular in shape, being provided with `a base flange I5 adapted to rest flatwise on the traverse bar and having slotted flanges I6 projecting therefrom for detachably securing the holder to such bar. The spinning ring I3 is detachably mounted on the holder and for this purpose has an annular flange I1 projecting therefrom for engagement at its marginal bottom side on the top edge of the holder, as shown in Figure 3. A split ring I8 is engageable with the marginal top side of the ring-flange I1 and is detachably anchored in-grooved lugs AIll rising fromY the holder for detachably clampin the drawing, the same is provided with an inner bearing face`20 which is oblique to the vertical and is ared downwardly and outwardly from a point adjacent the top' side ofA the ring, while the top side of the latter is provided with a downwardly and inwardly sloping bearing face 2I, and with which faces the traveler is adapted to enga-ge. Formed in this ring are one or more substantially transverse holes or por-ts 22 of small diameter through which lubricant is adapted to be conveyed for lubricating the inner ringbearing face, and one or more substantially upright holes or ports 23 of like diameter through which lubricant is adapted to be conveyed for lubricating the top ring-bearing face. By way of example, two sets of such por-ts have been shown at diametrically opposite sides of the ring and the transverse ports 22 communicate with alining passages 24 formed in the ring-flange I1. Depending from the latter outwardly of the holder, and adjacent each of such passages, is

a lubricant-receiving well 25. The ports 22 are slightly inclined to the horizontal preferably sloping downwardly and outwardly from the inner bearing face of the ring and their outer ends are preferably counter-bored as indicated at 26. The lower ends of the upright ports- 23 intersect these transverse ports in the plane of their counterbored portions wherebythey are in communicating relation with each other.

Wick elements 21 and 28 are fitted in the respective ports 22 and 23, the wick 21 being immersed at one end in the lubricating well 25 and extending through the companion passage 24 and the alining port 22, while the element 28, which is fltted in the port 23, extends at lts lower end into the counterbored portion of. said port. 22. Both wick elements are preferably composed of a lubricant-conducting core 29 of wool or other textile material extending from end to end thereof and a wire sheath 30 coiled about the same in the manner shown in Figures 4 and 5. That core portion of the wick 21 which extends through the ports 22, 24 is more or less densely or compactly formed by closely coiling the wire 30 about the same to thereby regulate the desired constant flow of lubricant to the bearing faces of the ring, while the remaining portion thereof is in a more or less loose state for ready absorption of the lubricant in the well, this latter condition being accomplished by a spacing of the wire coils about the core. The companion wick 28 has its core closely coiled by the wire sheath while its opposite feed and discharge ends are uncoiled or exposed to freely absorb and discharge the lubricant. The discharge end of the wick 21 is similarly formed for a like reason. In constructing these wicks they are preferably formed about a temporary stem 3l, as shown in Figure 6, which is removed after the wire 30 is coiled about the conducting core 29, leaving the center of the wick with a small lubricant-conducting channel. The wire sheath also serves to give a certain amount of rigidity to the Wicks to facilitate their insertion into the ring-ports.

A cover plate 32 is applied to the open top side of the well 25 and has openings 33 therein for the introduction of lubricant when necessary.

To limit and properly govern the insertion of the wick 21 in the alining port, 22 and passage 24 so that its discharge end is substantially flush with the inner bearing face of the ring, I provide such wick with`a shoulder 34 adapted to abut against the adjoining wall of the well 25, as shown in Figure 4. By way of example, this shoulder may be formed by displacing or offsetting one or two coils of the wick.

I claim as my invention:

A device of the character described, comprising a spinning ring having a traveler-engaging bearing face thereon and a lubricant-conducting port opening onto such face, a lubricant-receiving well applied to the ring having a passage leading therefrom and communicating with said ring-port, and a Wick threaded through said port; and said passage and in lubricant-conducting relation at one end with said well, said wick including a core of textile material and a wire coiled about that portion thereof extending from the well to said port to regulate the constant flow of lubricant to the ring-bearing face, said wick having a. stop thereon for limiting its threading operation through said passage and ring-port.

CHARLES FILLINGER.
