Abstract

196,634. White, A. E., (Metal Recording Disc Co., Inc.). Nov. 30, 1922. Right to Patent relinquished. Records, blanks for.-A blank upon which sound may be recorded by means of an ordinary gramophone consists of a tablet 1 of resistant composition or metal such as spelter, on which a volute groove 3 is initially formed, preferably by engraving. In use, the blank is rotated with the stylus 4 of the ordinary reproducing sound-box in engagement with the groove 3, which serves to guide the stylus. Vibrations of the diaphragms, caused by singing &c. into the apparatus, are recorded in the walls of the groove 3. The groove is preferably arcuate in cross-section, with a comparatively large radius, Fig. 5, or it may be angular, Fig. 4, the walls diverging at a large obtuse angle. Reference has been directed by the Comptroller to Specificatione 4315/97, 6613/06, 26529/11, and 153,087.
