Abstract

28,274. Midgley, A. H., and Vandervell, C. A. Dec. 3. Impeller blades.-A screw-fan impeller is formed from a blank a of sheet metal by stamping-out an eccentric hole b of about one-third the diameter, cutting the part e of the common diameter, and bending the parts to shape as shown in Fig. 1. The impeller is secured at i to arms h on a hub g. The part b of the blank may be used in making a smaller fan.
