Abstract

410,074. Gramophones; acoustic horns. KANDERS, H., 18, Rue de Ranelagh, Paris. Aug. 2, 1932, No. 21647. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 3, 1932]. [Classes 13 and 40 (ii).] A gramophone is provided with a sound conduit 7 which leads from the sound box 4 and penetrates into the side wall of a reflector 6 in a direction at right-angles to the axis thereof, the reflector having the shape of a solid of revolution of a conic section. The sound box 4 is mounted for universal movement by means of pins 14, Fig. 2, secured to the conduit 7 and supported by bearings 13 in the forked end 12 of a stand 9 which is mounted to rotate in a sleeve 10. According to a modified construction, the reflector 6 may be secured rigidly in the interior of the case 1, the tone-arm being connected to the conduit 7 by a ball and socket joint. In this case the conduit 7 is either supported rigidly by a bracket upstanding from the motor-board, or is socketed in the wall of the reflector, as shown in Fig. 4, to allow of rotation about a vertical axis.
