Description: |
| Abstract:
The nature of this invention relates to certain new and useful improvements in the construction of dynamo-electric machines, by which the electro-motive force of the machine is equalized or kept up to meet the different requirements on the line-as, for instance, when the machine is adapted to run twenty lights in a circuit, and it is expedient, from any cause, to extinguish at a certain time- a part of the lights, one after another, without warning to the central station. The device works automatically without attention, and the force necessary to run the lights will correspond to the number of such lights in actual use.
Claim:
In a dynamoelectric machine, a separate helix supplementary to the main helix of the field- magnet, the separate helix being so wound and connected that the machine working normally will not be influenced thereby, but on the current becoming abnormally strong said supplementary helix will be brought into action and tend to diminish the magnetism of the field-magnet, and automatically regulate the strength thereof to accommodate the outside work. |
