438. Hoffay, J. Jan. 7. Sound-boxes, balancing.-The tone-arm 1 of disk machines is provided with a beam 8 carrying a fixed or adjustable counterweight 7 to relieve the pressure of the needle on the record, and to increase the inertia of the system against movement of the stylus pivot. The bar 8 is preferably somewhat resilient, and may be so arranged as to prevent movement of the tone-arm in the wrong direction.
