Arrangement for fastening a phonograph stylus holder to the tone arm

An arrangement for fastening a phonograph stylus holder beneath its tone arm, comprising

• pins having a smooth cylindrical surface fixed to the tone arm and having downwardly converging frusto-conical lower ends which are rounded at their lower termini;
• sleeves situated in openings in the stylus holder and adapted to be slipped onto and frictionally to engage the pins, the sleeves being mounted on the stylus holder for rotation about respective axes parallel to external cylindrical surfaces of the sleeves to provide angular adjustment of the stylus holder with respect to the tone arm;
• internal passages within the sleeves that are eccentric with respect to the external cylindrical surfaces of the sleeves;
• and
• wherein the pins have downwardly converging frustro-conical lower ends which are rounded at their lower termini.

An arrangement for fastening a phonograph stylus holder beneath its tone arm, comprising

• pins electrically connected with at least one supply conductor for the stylus holder and having a smooth cylindrical surface fixed to the tone arm;
• sleeves situated in openings in the stylus holder and adapted to be slipped onto and frictionally to engage the pins;
• internal passages within the sleeves that are coaxial with respect to the external cylindrical surfaces of the sleeves;
• and
• flanges at the lower ends of the sleeves which overlap with the lower opposite edges of the stylus holder.
