Abstract

524,789. Gramophones. BISHOP, J. Feb. 7, 1939, No. 4077. [Class 40 (ii)] An arrangement for determining the starting position of a needle on a gramophone record especially for use in the production of theatrical effects, comprises a rod 23 with a collar 24 detachably mounted on a fixed support 22 and adapted to act as a stop against which the reproducer arm 12 abuts at a position on the record depending on the effective length of the rod between its end and the collar 24 which abuts against the support 22. Alternatively, the rod is mounted on the reproducer and its end abuts the fixed support. The collar 24 may be adjustably secured in desired position on the rod by a set screw 25. Two collars 24, 24a may be provided on the rod, which may then be used in one direction or the other according to the effective length desired. Several such rods may be provided. The support may be rotatably adjusted about a vertical fastening screw 13; this enables the angular position of the rod to be adjusted. The support is also provided with a lever 16 adapted to engage beneath an outwardly inclined arm 20 attached to the reproducer to lift and lower the same, the outward inclination of the arm helping the reproducer to remain in position against the stop while being lowered.
