Abstract

381,164. Gramophone records. LINK, R. P., 10, Millers Avenue, Hackney, London. April 25, 1931, No. 12290. [Class 40 (ii).] To facilitate the removal of a gramophone record disc from a pile, the central part of the disc is provided with a raised portion by attaching a smaller disc thereto by means of a metal bush. One such smaller disc may be attached on each side of a record disc. As shown, the record disc a has two smaller discs b attached to it by an eyelet or metal bush c. The Provisional Specification states also that the smaller disc or discs may be attached to the record disc by an adhesive or cement, and describes various modifications which include, (1) forming the central raised portion by embossing the record disc, the projecting part on one side being larger than the recessed portion on the other, and (2) moulding the record disc with a central portion of greater thickness than the remainder.
