Abstract
343,847. Screw propellers. MELCHER, F., 49, Gersthoferstrasse, and SCHNEIDER, E., 29, Blindengasse, both in Vienna. May 27, 1930, No. 16293. [Class 114.] In a screw propeller having concave blades the generating line is inclined at an angle B in the first third of the radial length adjacent the boss in a direction opposed to the direction of thrust, in the middle third of the length at 7 the direction is normal to the axis, and in the outer third the direction at 8 is at an angle a towards the direction of thrust.
