Abstract

24,552. Seymour, F. M. Oct. 22. Records.- Flexible record disks of celluloid and cellulose compositions are duplicated in a press A supporting the record blank C with the matrix B adapted to be forced down upon it by a screw E carried in a clamp D. A supply of steam or hot water at a pressure of 100 lb. per square inch is directed at the centre of the blank from a pipe F, thus driving outwards all air bubbles and moisture, which escape through peripheral apertures H. As the celluloid softens, these apertures are closed, and the steam pressure then finishes the transference of the sound impression in about two minutes for films twenty-thousandths of an inch in thickness. Cold air is then directed through pipes G, F. also under pressure, to cool the record, after which it is finished and removed.
