Abstract

102,989. Dickinson, J. H. Jan. 6, 1916 Cases. - A cabinet phonograph of the kind in which an enclosed horn is insulated from the cabinet has the tone-arm supported solely on the curved neck of the horn; and sounddeadening material is interposed between the cabinet and its lid. The horn 5 of rectangular section is supported at each end on felt or like packing inserted between it and the case. A curved neck 9 of circular section projects loosely through a hole 10 in the shelf 6 and carries the tone-arm socket 19, a rubber flange 22 being interposed between the neck and the socket.. The flange forms part of a tubular valve seating in which a valve 25 may be adjusted for varying the sound-intensity. The tone-arm 4 swings in the socket 19 and also carries a vertical pin 21 bearing in a bracket 20 secured to the socket 19. The machine may be arranged between the top and bottom plates 11, 31 of a semi-elliptical table, the compartment containing the turntable being open at the top and surrounded by a ring of felt 33. When a record is being played, a lid 32 hinged along the straight edge of the table is lowered, and an end door 38 opposite the mouth of the horn is opened. The felt ring may be mounted on the lid 32.
