Abstract

12,120. Sandahl, C. May 27. Drawings to Specification. Phonographs &c.-Plate records for sound-reproducing machines are prepared so that, for a given rate of vibration of the stylus, the same inscription is produced at all points of the surface of the plate. In preparing the record, the plate is rotated with an accelerating speed as the stylus moves from the edge to the centre ; or the speed may be retarded if the stylus travels from the centre to the edge.
