Abstract

133,339. Berry, F. E. Jan. 4, 1918. Transformers.-A transformer has a number of tappings on its primary or secondary winding connected to a main regulating-switch, and is associated with an auto-transformer with a supplementary regulating-switch. The secondary b is shown with tappings connected to the terminals b<1>, b<2>, &c. of the switch S, and a double contactarm c, d moves over the contacts to connect sections of the winding across the auto-transformer i. The supplementary switch S<1> connects the main g' to any of the tappings of the auto-transformer.
