SPINNING-RING.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed January 12, 1907. Serial No. 352,007.

To all whom it may concern:

Be it known that I, FRED H. CHAPMAN, a citizen of the United States, residing at Groton, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Spinning-Rings, of which the following is a full, clear, and exact description.

The object of this invention is to provide a spinning ring for ring-spinning frames, particularly for spinning cotton, wherein the tension on the thread as it is wound on the bobbin is regulated automatically by gravity, so that the same tension is given whether winding on full or empty bobbins and it is possible to wind an increased quantity of thread on the bobbins, and the tendency to ballooning is overcome, and so that separators need not be employed.

The invention consists of a spinning ring having a fixed part and a movable part connected with the fixed part and carrying the traveler, said movable part rising and falling with a circular movement upon the fixed part and acting as a gravity drag upon the traveler thereby to control the tension upon the thread to accomplish the object stated.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view. Fig. 2 is a side elevation with the left hand side in vertical section, the movable part being raised. Fig. 3 is a view like Fig. 2, but with the movable part lowered. Fig. .4 is a bottom plan view of the movable part detached. Fig. 5 is a top plan view of the fixed part detached. Fig. 6 is a top plan view of a construction showing the traveler flange divided between the fixed and movable parts. Figs. 7 and 8 are part side elevations and sections showing the ring of Fig. 6 in the raised and lowered positions, respectively. Fig. 9 is a part side elevation and section showing another form of connection of the bipartite ring, the movable part being raised. Fig. 10 is a side elevation of the ring of Fig. 9 with the movable part lowered. Fig. 11 is a part side elevation and section of the ring of Figs. 9 and 10. Fig. 12 is a rear side view, and Fig. 13 is a top plan view of one of the clips used in the construction shown in Figs. 9 to 11 to connect thetwo parts of the ring. Fig. 14 is a cross-section of a reversible ring, and Fig. 15 is a cross-section through ,the slot and pin connection of the reversible ring.

The holder comprises the horizontal baseflange 1 and the vertical annular sleeve 2, and the base-flange has the ears 3 by which it may be secured to the ring rail (not shown) of the spinning frame, or it may be provided with any other suitable attaching medium. This is the fixed part referred to.

As shown in Figs. 1 to 5, inclusive, instead of finishing the sleeve 2 with a horizontal flange for the reception of the traveler, there is provided an independent sleeve 4 which is constructed with the horizontal traveler-receiving flange 5. This sleeve 4 and its flange constitute the movable part referred to. The two parts of the ring are connected by any number of pins 6 made fast in the sleeve 2 and oblique slits 7 formed in the sleeve 4, the pins projecting into these slits 7 and held from escape therefrom by means of the inturned edges 8 of the slits,

these inturned edges forming stops and herein so designated. The two sleeves have a sufficiently loose connection to provide for the easy and relatively free movement of the sleeve 4: on the sleeve 2, such movement being a vertically up and down movement with a slight rotation or circular back and forth movement due to the obliquity of the slits and their engagement with the fixed pins. I

The traveler 9 may be of the usual char acter.

As shown in Figs. 6, 7 and 8, instead of having the traveler-receiving flange made entirely on the outside movable sleeve, a part 10 thereof may be made on the inside sleeve or fixed member and the other part 11 may be made on the outside sleeve or movable member.

As shown in Figs. 9 to 13, the fixed memher and the movable member may be connected by clips 12 having pins 13 secured to the movable member and pins 14 secured to the fixed member and feet 15 working on the base flange.

As shown in Figs. 14 and 15, the fixed member may be as in Figs. 1 to 5, but the movable member 16 may be a reversible ring, that is to say, one having a travelerreceiving flange on both edges, and these two may be connected by pins and slots 17 and 18, respectively, or any other suitable connection. Furthermore, these views, Figs. 14 and 15, show that this movable member, of whatever construction, may be arranged to slide inside of the vertical flange 2 of the fixed member, the only difference in construction in this particular being that the vertical sleeve of the fixed member would be of sufficiently increased diameter to admit a movable member of proper diameter.

The apparatus is arranged for operation in accordance with any approved method of spinning cotton yarns or the like, the material passing from the bobbin through the traveler to the spindle. As the spinning proceeds, when the pull on the thread is hard, the movable member rises until the stops come into contact with the pins, and as the tension decreases, the movable member falls downwardly and reversely thereby applying additional tension to the thread and thereby overcoming the tendency of the thread to balloon. When the tension becomes so weak that the movable member falls to its lowest position, then the traveler drags on the edge of the sleeve 2 and between that edge and the traveler-receiving flange of the movable member and thus applies the requisite tension. As shown in Figs. 7 and 8, this drag would be effected by the tilting of the traveler.

The construction shown in Figs. 9 to 13, wherein the clips 12 are used to connect the fixed and movable parts of the ring, operates in substantially the same way as the previously described construction in regulating the tension by gravity and serving as a brake. The feet serve as stops as the movable member rises. In all cases the traveler serves further to control the downward movement of the movable member.

It will be understood that a sufficient number of pins and slots or other connecting devices will be employed to insure a constant level and alinement of the parts. This re sult is contributed to by the fact that the connections are and should be such that the rising and falling movements of the movable member are simultaneously modified by circular or rotary back and forth movements. This circular or back and forth motion, however, is limited by the connecting devices and never amounts to a complete rotation.

These and other variations of the principle of my invention are within the scope of the claims herein made for a bipartite spinning ring comprising a fixed member and a movable member connected in such way that the tension on the thread is regulated by gravity, ballooning is prevented and the use of separators rendered unnecessary.

What I claim is 1. A spinning ring, having a fixed member and a movable member, means connecting said members and limiting the up and down and back and forth movements of the movable member on the fixed member, and a traveler applied to the ring, the movable member acting as a gravity drag on the traveler.

2. A spinning ring, having a fixed member and a movable member, a traveler applied to the ring, the movable member acting as a gravity drag on the traveler, and means to limit the upward and the back and forth motions of said movable member.

3. A spinning ring, having a fixed member and a movable member, and a traveler applied to the ring, the movable member acting as a gravity drag on the traveler, and connections between the fixed and movable members to guide the movable member and limit its vertical and restrain its horizontal movements.

4. A spinning ring, having a fixed member and a movable member, a traveler applied thereto, the movable member acting as a gravity drag on the traveler, and obliquely arranged connections between the fixed and movable members.

5. A spinning ring, having a fixed member and a movable member, and a traveler applied thereto, the movable member acting as a gravity drag on the traveler, and connections between the fixed and movable members whereby the movable member is capable of a compound up-and-down and circular motion.

6. A spinning ring, having a fixed member and a movable member, and a traveler applied thereto, the movable member acting as a gravity drag on the traveler, obliquely arranged connections between the fixed and movable members, whereby the upward motion of the movable member is limited, said movable member ca able of a compound upand-down and circu ar motion and of being maintained in arallel alinement with the fixed member t rough its course of motion.

7. A spinning ring, having a fixed member and a movable member, means to connect said members arranged to insure parallel alinement of the two throughout the course of motion of the movable member and to restrain its horizontal movement, and a traveler, the movement of the movable member being effected by the thread. 8. A spinning ring, having a holder provided with pins and a traveler-receiving sleeve fitted to the holder and having oblique slits in engagement with the said pins, whereby the traveler-receiving sleeve is capable of a compound rising and falling and circular movement.

9. A spinning ring, having a holder provided 'Wltll pins, and a traveler-receiving sleeve mounted on the said holder and provided with obliquely arranged slits in engagement with the pins and having stops to limit the rising and falling movement of the traveler-receiving sleeve.

In testimony whereof I have hereunto set my hand this 10th day of January A. D. 1907.

FRED H. CHAPMAN.
