Abstract

562,865. Screw propellers. HOLBERTON, B. V. Dec. 10, 1942, No. 17616. [Class 114] The hub of a variable pitch marine screw propeller comprises a cylindrical portion 10 having end flanges 14, 20, one of which accommodates the end of the driving shaft 19 and the other carries a pitch changing motor 27, local enlargements being provided in the bore of flange 20, whereby bearings 22 for the blade roots may be inserted into position. The enlargements also accommodate driving connections 28 between the motor and blades. The motor may be hydraulic or electric. The blade root bearings are secured in the manner described in Specification 562,863.
