Abstract

120,320. Higgs, W. F. Feb. 13, 1918. Impeller blades.-An impeller for attachment to the armature of an electric motor is formed from a circular blank, Fig. 4, in which are cut radial slits b terminating inwardly in circular or other enlargements c. The blades a<2> are twisted on their middle lines so as to project equally on each side of the plane of the central part a.
