Abstract
313,480. Oyston, W. R., and Lakin, F., A. March 12, 1928. Divided on 304,070. Drawings to Specification. Needles, changing automatically. - Relates to needle-changing devices for gramophones, more particularly automatic gramophones, such devices being of the kind wherein the movement of the sound-box or reproducer to and from a playing position controls the automatic changing, of the needle. According to the invention, means are provided whereby the movement of the reproducer from a playing to a non-playing position produces the release of the used needle, which is discharged from its holder, whereupon a new needle, fed automatically from a magazine, and substituted for the used noodle, is clamped in the holder on the reproducer during the return of the latter to playing, position, and prior to the engagement of the needle with the record to be played. The mechanism employed in carrying out the invention is described and illustrated in Specification 304,070, which describes a magazine gramophone wherein the present invention is embodied, and in which the records are played when in a vertical position.
