Abstract

245,212. Sloane, A. Oct. 6, 1924. Tool-arm mountings. - The tool arm 2 of a sound-box provided with a large diaphragm 1, for instance of 6 inches to 12 inches diameter, is supported from the rim of the sound-box 1<a> by a blade spring 3 which extends from a point on the stylus arm well within the circumference of the diaphragm. The spring may be of stepped form, as shown, and may be secured to the tool arm, by screws, brazing or otherwise, or may be formed integral therewith.
