Abstract

647,826. Gramophones. SOUNDSCRIBER CORPORATION. May 12, 1947, No. 12767. Convention date, Dec. 24, 1941. [Class 40 (ii)] In a gramophone in which the direction of travel of the groove under the stylus is towards the axis of the reproducer arm, the tendency of the stylus 6 to leave the groove under the action of the torque due to the friction between the stylus 6 and the disc 11, is opposed by a spring attachment which urges the reproducer arm towards a neutral sector. A spring attachment, Fig. 4, is fixed to an L-bracket 8 on which the arm 3 is pivoted and applies the counter-torque to the pin 24 by means of spaced parallel portions 27, 28.
