Abstract
702,287. Centrifugal fans. FABER, E., and HAHN, L., [trading as MAUZ & PFEIFFER, (Firm of)]. July 12, 1951 (July 6, 1950], No. 15579/51. Class 110 (1) In a bladed impeller for a vacuum cleaner, the whole of the blade structure is made of elastic, resilient material, preferably rubber. The impeller hub 2 carries a metal disc 3, on to which is vulcanized a rubber plate 5 carrying rubber blades 6. The blades are thicker at the base than at the free edges 9.
