Abstract

531,756. Variable pitch propellers. NORTHCOTE, J. S. June 14, 1939, No. 17371. [Class 114] In variable pitch propellers in which the adjustment of the propeller blades is effected by planetary gearing a sun wheel B fast on the propeller shaft A drives planet wheel C against the internal gear D causing the spider E to rotate. The spider E drives planet gear F against internal gear G causing the sun gear H to rotate at the same speed and in the same direction as the sun gear B. The rotation of the internal gear G by the control gear L causes the sun gear H to rotate relatively to the sun gear B this rotation being transmitted to the air screw blades by the gears I and J. In a modification, bevel gear is employed in the place of plain gear wheels. Both forms are applied to the adjustment of the blades of air screws arranged in tandem.
