Abstract
The ring mount is of a two-piece construction and includes a hard plastic mounting support fixed in an annular opening in the ring rail. An annular recess is provided in the upper inner portion of the mounting support. A soft plastic insert is adapted to closely fit within the annular recess of the mounting support and is provided with an annular groove in the inner surface which is adapted to receive and support the lower flange of the ring. The two-piece ring mount is positioned between the metallic ring rail and the metallic ring and provides noise and vibration dampening means for resiliently supporting the metallic ring on the ring rail.
Claims10
In a spinning frame including a metallic ring rail with spaced apart annular openings therein, a metallic ring supported in each of said annular openings, said ring including a main body and upper and lower flanges, a traveler supported on said upper flange for rotational movement around said ring, the combination therewith of improved noise and vibration dampening ring mounting means supporting said metallic ring and comprising
- (a) a hard plastic mounting support,
- (b) means for securing said mounting support on said ring rail and surrounding said annular opening,
- (c) a soft plastic insert supported within said mounting support and including an annular groove in the inner surface of said insert for receiving and supporting said lower flange of said ring, wherein the hardness of said soft plastic insert is no more than 75% of the hardness of said hard plastic mounting support so that said hard plastic mounting support and said soft plastic insert are positioned between said metallic ring rail and said metallic ring and cooperate to provide noise and vibration dampening means for resiliently supporting said metallic ring on said ring rail.
