Abstract

147,321. Forrester, J. H. May 27, 1919. Tools for reproducing; tool-arms.-The pointed end A of a stylus for gramophones and like machines is made of hard wood, ebonite, vulcanite, vegetable fibre, or like material, the stem C is made of harder material such as metal, and an enlargement E is provided between the stem and the point which abuts against the stylus-carrier when in position on the sound-box. The enlargement E may be integral with the pointed end A and may be secured by a cone and socket to the stem C, as shown in Fig. 1, or the stem may be screwed into the enlargement. Alternatively, the enlargement E may be integral with the stem C, as shown in Fig. 4, and may be socketed to receive the pointed end A. The socket may be split so as to grip the pointed end, or it may be held by a screw F.
