Abstract

602,261. Gramophone pick-ups. PHILCO RADIO & TELEVISION CORPORATION. June 28, 1945, No. 16498. Convention date, June 29, 1944. [Class 40 (iv)] [Also in Group XXXVIII] A phonograph pick-up of the capacity type comprises an elongated metallic strip 15 maintained flat and taut, which is closely spaced from a rigid metallic plate 26 by insulating means 29, 30 to constitute a condenser, the capacity of which is varied by the vibration of the strip by a stylus arm 19 carrying a stylus 3. The pick-up unit consists of a pair of outer insulating members 12, 13, between which is fitted a metallic member 14 having the strip 15 screwed thereto, the latter being maintained taut by a wedge 21 seated in a recess 22. The plate 26 is freely supported by the member 12, a bowed spring 28 serving to urge it towards the strip 15. Contact prongs 32, 31, connected to the plate and strip respectively, fit into corresponding receptacles in the tone arm, while a dummy prong is fitted to the member 13 for better securement.
