Abstract

455,599. Sound recording and reproducing machines. KOSMOGRAPHDIKTIERMASCHINENFABRIK GES., 24, Schandauer Strasse, and RYSICK, A., 194, Kipsdorfer Strasse, both in Dresden, Germany. March 18, 1935, No. 26378/36. Divided out of 455,553. [Class 40 (ii)] Relates to sound recording and reproducing machines, particularly for dictation. For the purpose of enabling thin flexible record discs to be used, according to the invention the turntable is provided with a rim 5 adapted to overhang the record disc 7, and is formed with one or more straight-edged shoulders 8 adapted to engage with the correspondingly shaped edge of the disc, to provide a positive driving connection. The rim 5 may be formed with a slot 6, through which the disc 7 can be slipped into position under the rim, where it is centred by a spring-pressed pin 4. Alternatively, the rim 5 may be hinged to the turntable. Specification 455,553 is referred to.
