UNITED STATES dPINNING RING.

Application filed October 15, 1824:. Serial Ro.'748,789.

TU'aZZ whom it mar concern:

Be it known that ALBERT L. THOMPSON, citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, has invented certain new and useful. Improvements in Spinning Rings, of which the following is a specification, reference being had therein to the accompanying drawin This mvention has reference to means for automatically and uniformly lubricating the ring and traveller elements of spinning or spooling machinery such as used in the cot-v ton, woolen and silk textile industries.

According to prevailing practice, the spinning ring is lubricated by hand a plication of the oil to the inner surface of the ring but .this method of application has proven to be unreliable, costly and wasteful, for the reason that it is practically impossible to eifect equal distribution of the oil toall parts of the moving machinery as required with the result that certain parts of the machinery are subjected to great wear causing wastage of both power and oil.

The purpose of my invention is to eliminate the foregoing objections by the provision of a self-lubricating spinning ring shaped to provide an integral oil reservoir extending entirely around the ring and provided with a series of spaced outlets leading from the bottom of the reservoir to the inner surface of the ring.

A further purpose of the invention is to provide a ring of the character specified which is so designed as to ermit the same to be manufactured and sol for a comparatively reasonable sum.

Other purposes, advantages and characteristic features of the invention will be more readily understood from the following detailed description and drawings wherein I have disclosed what I now consider to be,

a preferred embodiment.

In the drawing:

Fi ure 1 is a plan view of a spinning r ng constructed in accordance with my raven tion.

Figure 2 is the transverse sectional View of the ring.

. 8 for engagement with the usual type of signature.

' Referring more particularly to the draw-' ings, 5 discloses a spinning ring formed with a smooth, vertical, inner surface 6; At the outer surface the ring is formed, between its upper and lower'edges, with an annular enlargement or rib 7, having its upper edge portion extendedoutwardly from the body of the ring to provide a supporting flange ring rail. Between the flange 8 and the body of the ring 5, the upper surface of the rib 7 is provided with an annular groove 9 having side walls inclining inwardly toward the axis of the ring so that the groove extends partly through the ring body. The bottom portion of this groove is in communication with the inner vertical surface of the ring through a plurality of relative openings 10, passing through the ring body at right angles thereto. i y

In order to prevent the oil from escaping too freely from the groove or reservoir 9, I prefer to place in said reservoir an annular wick 11, which serves to hold the oil in suspension while permitting suflicient oil to be drawn through the openings 10 to uniformly r-Arenr orrlcs.

lubricate'the in'nersurface of the ring and body, an annular flange projecting outwardly from the body between its lower and upper edges, said body being rovided with an annular oove formed t erein at the base of said ange, said groove being formed with inner and outer walls inclining toward the axis of the ring as they approach the bottom of the groove, and said body being formed with a plurality of small openings extending inwardly from the said bottom of the groove to the inner surface of the body.

In testimony whereof I hereunto aflix my ALBERT L. THOMPSON.
