Abstract

417,927. Gramophones &c. SCHULER, H. A. H., 1, Gartenstrasse, St. Georgen, Schwarzwald, Germany. March 8, 1933, No. 7028. [Class 40 (ii).] A supporting arm 4 on which a gramophone pick-up or recording device 1 is pivoted about an horizontal axis 3 either directly or through a frame 2, is provided with a weighted lever 5 pivoted about the same axis 3, which lever exerts an upward force on the device 1 or upon a projection 6 on the frame, so as to relieve the stylus pressure. The counter-balancing force may be varied by arranging a weight 7 slidably on the longer arm of the lever, which is preferably graduated. A projection 8 is provided on the arm 4, to limit the fall of the lever 5 when the pick-up is swung upwardly.
