Abstract

440,587. Making screw fans. HUMBER, Ltd., WISHART, N. M., and DYER, L. L., Humber Works, Stoke, Coventry. Dec. 12, 1934, No. 35684. [Class 83 (ii)] [See also Group XXVI] Screw-fan blades are formed integrally with one another from a sheet metal blank by pressing. The central portion 12 of the blank is bent so as to be semicircular in crosssection and the trailing edges 15 are bent downwardly to an increasing amount from the tip to the central portion. Two segments 17 are outwardly turned to be parallel to the original plane of the blank and they are drilled at 18 to enable the impeller to be secured to a driving flange. The segments 17 are strengthened by a disc 19 and angle pieces 20.
