Abstract

363,627. Sound recording and reproducing apparatus. BLUMLEIN, A. D., 57, Earl's Court Square, London. Sept. 12, 1930, No. 27325. [Class 40 (ii).] The stylus shaft a of a moving-coil phonographic recorder or reproducer is formed with a fork k in which the stylus-arm h is clamped by screws with two pieces of cork, rubber &c. 1, 1 inserted between the arm and the shaft, the clamping screws not touching the stylus-arm. The cork &c. serves to damp oscillations of the stylus shaft and arm in unauthorized modes but has no damping effect on the movement thereof in their authorized mode.
