Abstract

532,028. Sound recording device. DANIEL, K. July 15, 1939, No. 20617. Convention date, Aug. 13, 1938. [Class 40 (ii)] An apparatus for cutting sound records on sound tapes and constructed as an oscillatory system is provided with means for positively limiting the amplitude of oscillations. As shown, a recorder 6 is carried by an arm 7 pivoted at 8 and counterbalanced by a spring 9 adjustable by a screw 10. The amplitude of oscillation of this system is limited by an adjustable screw 13 on an extension of the arm 7 co-operating with a fixed stop 14. In addition the oscillations are damped by a disc 11 attached to the arm 7 and immersed in an oil cup 12.
