Abstract
375,283. Gramophones. VATCHNADZE, G., 15, Rue de la Grotte, Paris. Dec. 20, 1930, No. 38451. Convention date, Jan. 3. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] Repeating mechanism for gramophones comprises a plate 1 rotatable with the record and an arm 8 which is pivoted on the plate 1 and is adapted, at the end of playing a record, to be engaged by the reproducing-stylus so as to carry the latter outwardly to its initial position. The turntable shaft 2 may be fitted with a rubber disc 3 which is notched for engagement with projections 5 on the plate 1. The arm 8 is urged towards the plate 1 by a spring 9, and the position of the arm 8 relatively to the plate 1 is adjustable by means of an eccentrically-mounted member 12. The end of the arm 8 is provided with a projection 15 which is adapted to deflect the reproducing-stylus, at the end of playing a record, on to a bevelled part 16 of this arm, and the stylus then moves along a groove 17 adjacent the bevelled part 16 while the arm is swinging outwardly of the record. When the stylus reaches its initial position it is deposited on to the record.
