Abstract

616,949. Magazine gramophones. HANSEN, H. C. Sept. 25, 1946, No. 28611. Convention date, June 14, 1945. [Class 40 (ii)] In a magazine gramophone designed for playing both sides of the records the transducer 16 is rotated 180 degrees by means of a lever 26 which has a toothed sector 36 in engagement with a pinion 36 on the transducer 16, and which co-operates with abutments 30, 32 so that when the transducer-arm 18 is lowered to'play the underside of a record 14 the stylus 22 is automatically turned upwards. In an alternative construction, Fig. 5, the underside of the record 14b is played before being lowered and the transducer 16 is rotated by means of a cord 52, pulley 54 and a member 56 co-operating with a cam 62.
