Description: |
| "In many places where electric motors are used it is essential that there be no break in the continuous operation of the system. Such is the case for instance in rolling mills, where a breakdown in the operating mechanism often causes a great loss due to the cooling down of the heated metal. In this rolling mills it is absolutely essential that the process be continuous. I have provided a system in which, in case of the breaking down of the driving motor, an emergency motor may be connected to the device to be driven, the injured motor being disconnected both mechanically and electrically so that it may be removed and repaired at leisure." |
