Title
[D8453ZAV], Letter from John T Perry to Thomas Alva Edison, February 14th, 1884
Editor's Notes
Sims man arrived but unable to make engine govern without heavier springs. He was instructed to run engine at 275 rpm, but your telegram instructed me to run dynamo at 1400 rpm to get proper EMF. Can we get this ratio using different pully arrangement?
