Abstract
A bobbin for use in a shuttle having a shuttle spring provided with grooves therein for receiving the rings of the bobbin. The bobbin has a resilient sleeve provided on a reduced diameter portion of the butt end. The sleeve has grooves provided therein for receiving the rings. Vibrations between the shuttle and the bobbin are minimized by the resilient sleeve thus reducing the wear of the shuttle spring.
Claims5
A bobbin for use in a shuttle having a shuttle spring provided with grooves therein for receiving the rings of a bobbin for securing the bobbin therein, said bobbin comprising:
- an elongated shank portion,
- an enlarged diameter cylindrical butt end integral with one end of said shank portion,
- a reduced diameter intermediate cylindrical portion provided on said butt end of said bobbin,
- a resilient sleeve carried on said reduced diameter portion of said butt end, and
- a plurality of longitudinally spaced metal rings carried on said resilient sleeve, said rings being separated and independent from each other, and
- means for retaining said rings on said sleeve so when said rings of said bobbin are inserted in said grooves of said shuttle spring movement between said rings and grooves of said shuttle spring are minimized by said resilient sleeve absorbing shocks and minor deflections of said shank portion.
