Abstract

321,275. Walter, C. M., Marsh, R. G., and Charles, W. J. Sept. 12, 1928. Tone-arms.-To ensure radial tracking of the sound-box a and its stylus across the record, the tone-arm b is connected to a tube c which is guided in a fixed sleeve d arranged radially of the turntable. The tube c is fitted with rollers j adapted to traverse a rod f extending through the sleeve d. In the construction shown, the rollerspindles k are pivoted on grub-screws l so as to permit rocking of the tube c due to irregularities in the record.
