  • Patent number: 4281576
    Abstract: In a bridge for stringed instruments of the type including a base member, a plurality of drums, and means connecting the drums to the base member in end-to-end relationship for independent lateral movement in two orthogonal directions to separately adjust the length and height of each string, there is disclosed an improved construction wherein the strings are conducted into engagement with the drums so as to apply an axial force to each of the drums to urge all of the drums axially into contact with each other and the first drum into contact with a fixed abutment on the base member.
    Type: Grant

    Date of Patent: February 21, 1978
    Inventor: C. Leo Fender
  • Patent number: 4046050
    Abstract: A string post for a musical instrument of the type which extends perpendicular to the instrument head and is adapted to be rotated manually to tighten a string wrapped therearound, the string post having a constantly decreasing diameter from the outer end thereof to a plane closely adjacent the instrument head so as to urge a string wrapped therearound toward and into contact with the instrument head.
    Type: Grant

    Inventor: C. Leo Fender
  • Patent number: 4031799
    Abstract: In a bridge for stringed instruments of the type including a plurality of independently movable drums which permit independent adjustment of the length and height of each string of the instrument, there is disclosed an improved construction wherein all of the drums are urged axially into contact with each other and a fixed post to reduce vibration of the drums and wherein the adjustment holes through the drums are arranged to prevent fraying of the sleeve of a player of the instrument as such sleeve passes over the bridge.
