The mechanical regulation of maximum output was effected by a centrifugal gOVOHIUL which kept the speed of the machine constant For that mason this generator may be placed in the Clll of me chanically mgulated machines of "constant-snow constant-current. ariatinns in speed are taken mre of by the automatic friction" type of f'lultl). The friction clutch (A and B) will lip more or less according to the speed of the engine, and the amount of such slippage is controlled by a governor. As soon as the speed of the armature inrre__ beyond the rated number of revolution, the governor will act. on the friction clutch. In other words, the two clutch halves (A and B) will be pulltd apart and slip in such a manner that the armature will rotate not faster than the predetermined speed
