- Editor's Notes
- "We have recently had a great deal of trouble with high bars in our commutators. This trouble is owing to the mica insulation which we use. This insulation would seem to be unsatisfactory, and at the same time, expensive. I understand that at Pearl St. they now use an asbestos insulation, which is very cheap and Mr. Beggs assures me, extremely satisfactory on the large 'Jumbo' machines. Would it be possible for you to take up this matter and give us something better than the mica insulation and at the same time, something very much cheaper."
