SPINNING-RING.

SPECIFICATION forming part of Letters Patent N 0. 536,566, dated March 26, 1895.

Application filed August 24, 1893. Serial No. 483,890. (No model. I

To aZZ whom it may concern.-

Beit known that 1, JAMES FOWLER, of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvementsin Spinning-Rings; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in spinning-rings. i

The object of the inventi s to so construct a spinning-ring that by the use of trav: elers an automatically varying tension may be exerted on the yarnsjoeing spun.

The invention consists in the peculiar construction of the spinning ring arrahf gd to provide independent flanges on which winding and tensRmQaveler-s may move.

The invention a so-consists in the peculiar combination of the flanges with each other and the use of two independent travelers.

Theinvention further consists in such other peculiar features of construction and combination of parts as will hereinafter be more fully described and pointed out in the claims.

Figure 1 represents a plan view of the improved spinning-ring with the winding and tension travelers on their'respective flanges. Fig. 2 represents an elevation of the same. Fig. 3 represents a vertical sectional view of the ring to more clearly show the construction thereof.

Similar numbers of reference designate corresponding parts throughout.

Yarn, to be perfect, must have a uniform twist and tension from the empty to the full bobbin. This has not heretofore been practicable with a single traveler serving as a constant factorin winding and twisting, while the power and peripheral speed of the bobbin is subject to constant variation during the winding of the yarn thereon. In the ordinary single spinning-ring it is found that the tension exerted by the traveler on the yarn does not prevent the ballooning of the yarn between the traveler and the pig-tail thus requiring the use of separators to prevent the yarn being woundvon'one bobbin from inter 5o fering with that which is being wound on to the bobbins carried by the adjoining spindles. When ring-rails are warped, or the rings are out of true, an unequal twist is given to the yarn by the varying movement of the travclear and the rings and travelers are subjected foundue wear while the breakage of the yarn is considerable.

In carrying my invention into effect it has been my object to overcome the abovennen the outer or tension ring having an inclined 7o traveler-flange 1O concentric with the flange of the inner ring and furnished with outer and inner race-ways for the ends of the traveler, a vertical, circular wall 11 supporting the flange 10, and an inwardly-turned bottom flange 12 the circular opening in which closely embraces the sleeve 5 of the inner ring and bears against the shoulder 6. Through the wall 11 are cut ports 1313 through which lint or dust may be removed, and surround- 8o ing the sleeve 5, below the bottom flange 12, is a collar 14 adapted to support this botto'm flange with its wall 11 and flange 10. On the inner flange 7 is carried a traveler 15 of the usual construction, but generally very light, and on the outer flange 10 is carried the tension traveler 16 the weight of which is determined by the size of yarn to be spun as well as by the diameter of the empty bobbin to be used.

It is obvious that the cohstruction of the rings may vary considerably from that shown in the drawings. They may be constructed from one piece of metal or may be secured together in a different manner, while the 5

flanges

7 and 10 may have any desired crosssectional shape or may be inclined more or less from the horizontal. If found to be desirable the flange 10 may extend in a vertical plane, or may be located above or below the [O0 flange 7, the object being broadly to provide two independent; traveler flanges; for each spindle, on which travelers may move independently of each other.

In threading,the yarn is first passed through the traveler 16, then through the traveler andis then carried to the bobbin. Atthe commencement of the spinning the two travelers, will, under normal conditions, travel at about the same rate of speed. Should the yarn, however, be delivered faster than it is being spun it is evident that the tension traveler 16 will fall back and take up the slack, while, when the diameter of the bobbin becomes enlarged by the winding thereon of the yarn, a tension will be automatically created by the drag of the tension-traveler which will tend to reduce the speed of the winder traveler. Where the rings are not exactly concentric to the spindle the tension traveler will take up the surplus yarn on the short side of the-ring nearest to the spindle and will allow it to be drawn out on the side farthest from the spindle. The tension traveler will also take upthe surplus yarn between the winder traveler and the rolls preventing this yarn from lapping around the rolls and being broken, or from ballooning.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In aspinning-ring, the combination with an inner annular traveler-flange, and a winder-traveler movable on said flange,of an outer flange embracing and connected to the inner flange, and a tension-traveler movable on said outer flange.

2. In a spinning-ring, the combination with an inner traveler-flange having a securing sleeve, and a traveler movable on said-flange, of an outer traveler-flange mounted on said securing-sleeve and a traveler movable on said outer flange.

3. The combination with an inner spinningring having, a securing-sleeve 5 a travelerflange 7, and the traveler 15 movable on said flange7 of an outer ring having the travelerflange 10, the wall 11 provided with ports l3=-13, the bottom flange 12 secured to the sleeve 5, and a tension traveler movable on the flange 10, as and for the purpose described.

In witness whereof I have hereunto set my hand.
