Abstract

Tone-arm joints.-Relates to means for pivoting the tone-arm of a gramophone, of the type comprising a bearing in a base socket and an upper bearing carried by an arm extending from the base. Three main parts are provided, which can be made by pressing or drawing, and assembled without screws. These parts consist of an arm i carrying the upper pivot q for the tone-arm, a base d, and an internal sleeve m, the lower portion of the arm being formed as a split ring h which fits within the base and is held tightly therein by the sleeve m. The lower edge of the split ring is flared at k to limit its upward movement. Ball bearings may be provided between a shoulder n on the sleeve and the outwardly bent edge o of the tone-arm p.
