Abstract
627,829. Propeller blades. COMPAGNIE GENERALE D'ELECTRICITE. Oct. 2, 1945, No. 25596. Convention date, Aug. 24, 1939. [Class 114] Helicoidal threads 2 or parallel notches, provided on the root 1 of a propeller blade to secure it to a socket 3 or liner formed correspondingly, have an angular profile comprising a long side of slight inclination to the axis of the blade and forming the active part of the thread or notch and a short side facing the inner end of the root of the blade, this side being more inclined to the axis but lying beyond the perpendicular to the axis passing through the junction of the two sides. The threads or notches in the blade root are disposed on a cone enveloping the paraboloid of equal resistance of fastening of the root of the blade.
