Abstract

538,527. Sound recording and reproducing apparatus. DAVIES, H. Feb. 29, 1940, No. 3819. [Class 40 (ii)] A lever 8 carrying a recording or reproducing head 9 at one end and a counterbalancing weight 10 at the other end is suspended by a pivot 7 from an arm 6 mounted on pivot 5 substantially parallel to the pivot 7, the arm 6 is held down by gravity against a stop in the operative position, and the lever is lightly pressed on the sound record by a spring 11 between the lever and the arm and anchored to one of them. As shown, the spring 11 is a long black spring anchored at one end 12 to the lever 6 and pressing on the lever 8 at its other end. The effective pressure is regulated by a pin 16 adjusted by a screw 14. The plane through the centre of gravities of the head 9 and weight 10 may pass through the pivot 7 or lie slightly below this.
