Abstract
364,610. Gramophones. McCLATCHIE, S., 21, Osnabruckerstrasse, Wilmersdorf, Berlin. July 4, 1930, No. 20386. Convention date, July 4, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] In a gramophone pickup, the needle (not shown) is clamped to a tubular armature 12, Fig. 2, by the part 21 of a spring clamp 20, the part 21 passing through an opening in one side of the armature and serving as a pivot about which the armature and needle turn. Alternatively, a wire 21a, Fig. 8, enters the armature 12 to clamp the needle 17 and may be bent out to release the needle by an arm 30.
