  • Patent number: 4562766
    Abstract: A stringed musical instrument has separate members commonly mounted at the head of the instrument for providing individual support and adjustment for each of the strings. Each fastening and tuning member comprises an elongated support piece carrying a clamping member that engages and clamps the string. The clamping member comprises a lever member releasably moved to a locked position for providing positive engagement with the string. The tension in the string is adjusted for tuning purposes by longitudinally displacing the elongated support piece.

  • Patent number: 4378723
    Abstract: A stringed musical instrument has separate members commonly mounted at the head of the instrument for providing individual support and adjustment for each of the strings. Each fastening and tuning member comprises an elongated support piece carrying a clamping member that engages and clamps the string with the clamping action increasing as the string is tensioned. The tension is adjusted for tuning purposes by longitudinally displacing the elongated support piece. In the preferred embodiment, the clamping member is a slidable button operating on a forced wedge principle.

  • Patent number: 4141271
    Abstract: This method and apparatus prevents improper string return by restraining an end portion of a string of a stringed instrument, such as a pedal steel guitar, free of longitudinal movement with changes in tension of the string from a predetermined level of string tension. The invention also involves applying tension force to the string operatively collinearly with a linear projection of an end portion of the string while maintaining an end portion of the string free of longitudinal movement with changes in string tension from a predetermined level of string tension.
