Abstract

122,290. Dufty, N. E. Feb. 13, 1918. Controllers for continuous or alternating current motors are constructed in the form of a drum D, with two or more contacts C<1>, C<2> arranged around its interior, these being connected by mercury, which is spread out in the form of a film by centrifugal force, when the drum is rotated.
