Abstract

374,398. Recording sound. FAY, H. P., 55, Holland Park, London. July 1, 1931, No. 5650/32. Divided on 371,935. [Class 40 (ii).] To enable a disc record to be made on an ordinary gramophone, a recording sound-box d is traversed radially across a metal or other blank x on a turntable a by means of a rack bar o pivotally connected to the sound-box and driven by a spiral scroll formed on a boss i which is located at the central portion of the turntable and constitutes a cage for ball bearings in rolling contact with opposed relatively rotated surfaces. These surfaces are respectively the upper surface of a base g rotated by the turntable spindle and the undersurface of a slotted guide member j for the rack bar o. The spiral scroll is stated to be rotated at half the speed of the turntable. Other details of the apparatus are set forth in Specification 371,935.
