Abstract
378,811. Gramophones. ST. MARTIN, G., 14, Rue Ferdinand Flocon, Paris. March 4, 1932, No. 6616. Convention date, March 17, 1931. [Class 40 (ii).] Means for driving a gramophone record at constant linear speed relatively to the stylus comprises a casing 8 which contains a governorcontrolled friction disc 11 engaging the face of the record and is connected to the sound-box 1 so as to pivot about a vertical axis and to have longitudinal movement along such axis. The connection between the sound-box 1 and casing 8 consists of an arm 4 provided with an apertured enlargement 5 for engagement with a spindle 6 on which the casing 8 is pivoted by means of bosses 9, 10. The distance between the bosses 9, 10 is greater than the width of the enlargement to allow the desired vertical movements of the casing. The wheel 11 drives the centrifugal governor 15 by means of a pinion 12 and worm 13.
