HOLDER FOR ROTARY SPINNING-RINGS.

Specification of Letters Patent. Patented Mar. 22, 1910. Application filed July 22, 1909. Serial No. 508,920.

To all whom it may concern:

A single screw 21 is sufficient to bind a ring holder formed with a neck portion 20, whereas two screws are necessary for those ring holders which do not have a similar portion but which bear solely upon the top of the rail.

Freedom of manipulation of the screws is apparent, since neither the spindles nor any other part of a spinning machine may be an obstacle.

Having thus explained the nature of my said invention and described a Way of constructing 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, what I claim is:

A holder for a rotary spinning ring, comprising two members, to wit; an annular cylindrical neck extending Vertically, and an annular supporting member for a spinning ring, said neck and supporting member having complemental portions adapted to be interengaged to lock them together, and said supporting member having an annular seat for contact with a spinning ring, and upwardly extending tongues for loose engagement with the interior of the ring.

In testimony whereof I have afliXed my signature, in presence of two witnesses.
