Abstract

509,013. Fan blades. GENERAL ELECTRIC CO., Ltd., and. WARD, L. G. Jan. 6, 1938, No. 420. [Class 114] A fan blade is formed from a flat or cambered plate and has its greatest width at about twothirds of its length from the free end, the width decreasing in both directions from this greatest width.
