Abstract

146,832. Eureka Vacuum Cleaner Co., (Assignees of Stecker, A. J.). May 21, 1917, [Convention date]. Impeller blades.-Blades formed of tempered spring metal are held on the hub by a plate K and a cap Q. The blades are made in pairs B, B<1> with a web F between, which is seated on a flat surface on the hub E. A notched plate K engages shoulders M on the blades at its periphery and flanges N on the web F at the hub. A cap Q with flanges R fitting over the webs F is fitted over the other end of the hub E. A radial stiffening rib is formed on each blade.
