Abstract

664,153. Screw propellers. RICHARDSONS. WESTGARTH, & CO.. Ltd., HUNTER, H., and DORRAT. J. A. March 9, 1950 [Jan. 13, 1949], No. 981/49. Class 114. A marine propeller is made from plates and sections by welding. the face plates of the blades merging through curved surfaces to form the surface of the boss. The boss is formed from end plates 10, and intervening substantially circular plates 18 with projections which are welded to internal webs of the blades. The blade may be filled with shavings, pitch or similar materials.
