Patent GB-138994-A (GB)
Title: Improvements in or relating to talking machines and the like
IPC: G11B17/02
Filed: 1919-02-17
Abstract: 138,994. Barnett, C. J. Feb. 17, 1919. Starting and stopping; sound-boxes, raising and lowering.-The control switch of a motor driving a talking or like machine comprises a two-armed lever actuated by two solenoids which are in series with switches closed by the tone-arm when it is in the starting and finishing positions respectively. The stopping-solenoid is also in series with the motor-starting switch, and the starting- solenoid in series with a switch closed by the second arm of the two-armed lever. The soundbox is raised by the lever when the motor switch is opened. A pair of horizontal arms 33, 34, clamped to the vertical portion of the tone-arm 16, are arranged to close switches 29, 31 respectively when the tone-arm is in its extreme positions. These switches are in circuit respectively with two solenoids 27, 26 the cores of which are attached to a centrally pivoted lever 19 carrying U-shaped switch members 20, 21 at its outer ends co-operating with mercury cups 22, 23. Fig. 4 shows the position of the switches when a record is being played, the circuit of the motor 8 being completed through the switch 21, 23. When the last record groove is reached, the arm 34 closes the switch 31, thereby energizing the solenoid 26 and tilting the lever 19. The motor switch 23 is thus opened, and the switch 20, 22 closed. When it is desired to re-start the machine, the tone-arm is moved beyond its starting-position so as to close the switch 29, thereby energizing the solenoid 27, tilting the lever 19 to the position shown in Fig. 4, and re-starting the motor. A toothed sector 35 attached to the lever 19 gears with a pinion on the shaft of a fly-wheel 37, thereby ensuring the complete closure of the switches 20, 21; or a tumbling weight may be used for the same purpose. As the lever 19 is tilted to stop the motor, the tone-arm and soundbox are raised by a rod 18, or, alternatively, the turntable may be lowered. When an alternating- current supply is used, eddy-current relays may replace the electro-magnetic relays 26, 27. A dash-pot may be employed to retard the closure of the motor switch 21, 23. The switches 29, 31 under the control of the tone-arm may be closed by springs when a trip mechanism is released by the tone-arm. The sound-box is connected to the tone-arm in the manner described in Specification 138,995, and the motor and driving mechanism are arranged as described in Specification 136,380.
