摘要:
Arrangement for fastening a phonographs stylus holder to its tone arm. The arrangement has a plurality of pins affixed to the tone arm, and sleeves inserted in openings in the stylus holder. The sleeves are slipped onto the pins and have a frictional engagement therewith. The lower ends of the sleeves are provided with flanges which underlie opposite edge portions of the stylus holder. In one embodiment of the arrangement the passages through the sleeves are concentric with the external cylindrical surfaces of the sleeves, and in another embodiment the passages through the sleeves are eccentric with respect to the outer cylindrical surfaces of the sleeves whereby turning of the sleeves permits an angular adjustment of the stylus holder with respect to the tone arm. Indicium means may be provided on the sleeve to indicate the angular position of the sleeves relative to the stylus holder.
