Abstract

110,075. Lewis, A. Jan. 13, 1917. Sound - boxes, mounting and insulating; tool arms and mountings.- The stylus bar of a phonographic sound-box for recording or reproducing sounds is pivoted to a bracket which is mounted with interposed sounddeadening material between the backof the sound-box and the tone-arm connecting tube. Fig. 1 shows the sound-box in elevation, and Fig. 4 is a horizontal cross section. The stylus bar b, h carrying the stylus i is mounted on knife edges b which are pressed against lugs a' on the bracket a by springs. b<1>. The lugs a' are in vertical alinement and are formed on horizontal arms projecting from a disk which is secured by screws to the sound box c with interposed washers d of sound-insulating material. A second pair of lugs a<2> form seatings for the springs b<1>. A sleeve f of rubber &c. passing through the back of the sound-box c, and an annular disk g of similar material, insulate the .bracket a from the tone-arm connecting-tube c.
