Abstract

919,369. Cleaning gramophone pick-up styli. DECCA Ltd. Dec. 14, 1961 [Sept. 30, 1960], No. 33665/60. Class 40 (2). A brush 20, rotated by a hand wheel 32 or by mechanism associated with the lowering of the pick-up arm on to a rest 15, brushes the resting stylus in a direction corresponding to that of a record groove during play. Damage to stylus mountings, particularly those of the type described in Specification 856,997, is prevented by a ratchet means 33.
