Abstract

274,724. Bunkenburg, A. Jan. 7, 1927. Impeller blades. - Screw propellers and windmills having multiple blades one behind the other are constructed with blades in axial alignment each with a cross section of double curvature. The blades d, d<1> supported by arms c, c<1> on the boss b are substantially rectangular in outline, of double curvature in cross section, and in axial alignment. The blades are connected together at the tips by plates e, e'.
