SPINNING-RING.

SIEGIFICATIQN forming part of Letters Patent No. 739,739, dated September 22, 1903. Application filed June 28,1901. Serial No. 66,358. (No model.)

To all whom it may concern:

Be it known that I, M IOHAEL E. SULLIVAN,

of New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Ring-Spinning Machines, of which the following is a specification.

Thisinven tion has relation to ring-spinning machines of the type wherein a rotary ring is employed to cooperate with the traveler in ported at points below a transverse median plane, and hence the object of this invention is to provide for reducing friction between the ring and the casing and to provide for the steadying of the ring during its rotation.

These ends I accomplish by forming the easing in two parts, one of which is rotatable relatively to the other, and by arranging the rotatable portion of the casing in such way that it engages the ring at or near the top thereof.

Referring to the accompanying drawings, which represent one embodiment of the invention, Figure 1 shows in section a rotary ring having my improved casing. Figs. 2

e and 3 show the stationary portion of the ring.

Figs. 4 and 5 represent the movable portion.

The ring, which is indicated at 10, is provided at its top with the two flanges 11 and 12, which constitute a race for the traveler At its lower end the ring is formed with the external flange 14. The ring is held yieldingly in place by a two-part casing comprising the metallic member or ring 16 and the fiber member 17. The fiber member 17 0 is in the shape of an inverted frusto cone, so

that its upper end projects under the flange 15 and its lower portion fits in the aperture in the stationary member or ring 16. The said part 17 is provided with a shoulder 19,

which is adapted to rest on the said casingsection 16.

The ring 10 is capable of axial and lateral movement relatively to the casing-section 17, while the latter is likewise capable of vertical and axial movement relatively to the stationary section 16.

From this description it will be seen that when the ring is rotated at a high speed it will tend to seek a center of motion within the movable section 17, and the latter will in turn seek to find its center of rotation within the stationary section 16. In practical operation, however, the casing-section 17 rotates slightly relatively to the rapidly-moving ring 10 and supports it at'or near its top, so that the latter is free from the gyratory movement ing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1. The combination with a laterally-yielding rotary ring, of a two-part casing therefor, consisting of two ring-like members, one of which is rotatable relatively to the other.

2. The combination with a laterally-yielding rotary ring, of a two-part casing therefor, consisting of a fixed member, and a rotary member, said rotary member being Wider at its top than at its bottom.

3. The combination with a laterally-yielding rotary ring, of a two-part casing comprising two members, one of which is fixed and the other is rotatable, said rotatable member being bodily movable laterally with respect to said stationary member.

In testimony whereof I have affixed my sig-' nature in presence of two witnesses.

MICHAEL E. SULLIVAN.
