Abstract
366,995. Gramophones; records. KINGSTON, A. W., 9, Newman Street, Oxford Street, London. Oct. 14, 1930, No. 30721. Addition to 352,391. [Class 40 (ii).] The apparatus described in the parent Specification for recording sound on a blank by a recording device which is traversed by a guide thread provided in the turntable, or in a disc underlying the blank and extending outside it, is provided with means for locking the blank to the thread guide disc during recording. As shown, these means comprise double keyhole slots 14 in the blank 13 to take over headed pins 16 secured to the guide disc 11. A soft paper disc 18 may be inserted between the blank and guide disc to ensure a grip action, or the edges of the wings of the keyhole slots may be bent up to form wedges for this purpose. The double wings of the slots provide for the blank being applied either side up. Reference has been directed by the Comptroller to Specifications 24509/01, [Class 40, Electric telegraphs &c.], and 334,003, [Class 40 (ii), Phonographs &c.].
