Abstract

141,600. Charles, H. B. Sept. 9, 1919. Diaphragm mountings; tool arms and mountings.-The diaphragm A of a gramophone is held in compression against a resilient ring B by the action of springs C which, in the modification shown, are attached at one end to lugs E on the sound-box and at the other end to the yoke F of the tool-arm, which is pivoted on a ball-andsocket joint J. In another form of the device, the ring B is on the right or inner side of the diaphragm and the lugs E on the outer side.
