Abstract

433,618. Screw propellers. CARIDROIT, J., and SOC. S.C.E.M.M.I.C., 10, Rue de la Pepiniere, Paris. Feb. 13, 1934, No. 4722. [Class 114] Screw-propeller blades 3 are formed by a generatrix which is an involute of the circle of radius r, the foot of the generatrix being moved along a helix a, b on the boss 2 and at the leading and trailing edges lies in planes perpendicular to the axis 1.
