Abstract
273,966. Salthouse, J. E. Dec. 18, 1926. Drum controllers. - In a' drum or like controller for varying the circuits of electric motors or other apparatus the stationary contacts D are mounted on rings C forming part of a frame A which surrounds the rotatable contact members H. The contacts may be insulated from the rings and may be electrically connected in groups with resistance for series-parallel and braking control.
