To all whom it mug (12/100172:
30 it known that I, CHARLES E. Tamr- BRIDGE, residing at Whitinsville, in the county of Worcester, State of Massachusetts, have invented and produced a new and original Design for a Spinning-Ring, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.
Figure 1 shows in plan view a spinningring, showing my design; Fig. 2 a partial seetional view of the same.
The leading feature of my design consists in an annular rounded rib rising a short distance from a plane surface midway between the upper and lower flanges of the spinningring upon the outside or inside, or both, and of aless diameter than that of the upper and lower flanges.

said rib a5 projecting from a plane face, and said ring has an annular ribuf on it intcriorly between the upper and lower flanges d a said rib a rising from a plane face, the ribs (ll a being rounded, as shown in Fig. 2. It will be noticed that the annular ribs (L2 a extend beyond the plane part of the ring for a less distance than the flanges above and below them and that they are located between the flanges and wholly within the circle oecupied by the flanges and are rounded in cross section.
I claim The design for a spinning-ring, substantially as herein shown and described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
