Abstract

129,655. Solaro del Borgo, B. July 11, 1918, [Convention date]. Tool arms and mountings. - The stylus lever of a phonographic soundbox comprises a member 3 pivotally mounted on the casing, a rigid styluscarrying arm 2 adjustably secured to the member 3, and a resilient arm 7 fixed to the member 3 and connected to the diaphragm 8. As shown in the Figure, the stylus-arm 2 is adjusted in effective length by screwing it into the member 3, on which it is locked by a lock-nut 1 or by a set-screw 6. Alternatively, the adjustment may be effected by a worm and rack.
