Abstract

352,242. Gramophones. McCLATCHIE, S., 21, Osnõbrucker Strasse, Wilmersdorf, Berlin. June 30, 1930, No. 19841. Convention date, June 28, 1929. [Class 40 (ii).] Comprises an electric pick-up supporting arm which is carried by a single-joint supporting element to permit horizontal and vertical movement of the pick-up. A supporting arm 1 is rigidly connected with a pivot pin 2, the point 3 of which rests in a bearing 4 and which is continuously held against a slotted guide 6 by a spring 5. The pivot pin 2 is held, when the arm 1 is in its raised position, by means of a lateral recess 11 in the guide 6 into which the pivot pin 2 is urged by the spring 5. Release is effected when the arm is turned outwardly to bring the needle into contact with the outer grooves of the record by the arm striking against the edge 12 in the casing 10 to cause the pivot pin 2 to swing out of the recess 11. Various other means are also described for holding the supporting arm in its raised position. The Specification as open to inspection under Sect. 91 (3) (a) mentions also, but does not describe, the application of the invention to supporting means for an acoustic gramophone sound box. This subject-matter does not appear in the Specification as accepted.
