Abstract

598,991. Screw propellers. RATIE, P. P., and RATIE, R. J. Aug. 14, 1945, No. 20946. Convention date, Feb. 24. 1944. [Class 114] A variable pitch propeller hub, in which the stem of the blade 1 is journalled in the arm 3 of the hub, has a threaded sleeve 5 transmitting to the hub the centrifugal forces applied to the blade and also embracing the hub arm 3. A ball-thrust bearing 9 compensates for axial play of the blade.
