Abstract

144,205. Bailey, W. C. Dec. 12, 1919. Tone-arms; sound-boxes. - In a gramophone- &c. having two sound-boxes, sensitive to base and. treble sounds respectively and connected to the same stylus, the tone-arm is longitudinally divided by a partition a<1>, Fig. 2. Sounds from the two sound-boxes travel by way of their respective compartments a<2>, a<3> to a common sound-chamber c, whence the bass tones are deflected along the arm c<3> by a deflector c<1> of thin sheet brass or other metal, while the treble tones are deflected along the arm c<4> by a thick deflector c<2>, preferably of hard wood. The goose-neck a<6> carrying the sound-box b<1> is supported by a spring arm d.
