18,760. Harrison, G., [Gramophone Co.]. Aug. 30. Phonographs &c.-Records are provided with a subsidiary tuning-record for the purpose of regulating the speed of the motor. This tuning-record B is formed by sounding a tuning-fork or other standard instrument while the motor is running at the same speed as when the main record A is made. The motor of the reproducing-machine is adjusted until the same note is given out by the tuning-record.
