Abstract

659,137. Variable-pitch propellers. DUERR, E., and YOUNG, G. I. April 26, 1949, No. 11041. [Class 114] The blade 4 has its blade area offset from the axis of the root which is screwed into the bore 3 in the boss 1, this offset area causing the blade to turn to the fully feathered position when the vessel is proceeding without the rotation of the propeller. A pin 8 engages a slot 7 in the blade root to limit the blade movement in the positive pitch position when rotating. Pins 11 on an adjustable shaft 9 allow the blade to be locked in a positive pitch position if the shaft 2 is to be rotated to give astern motion.
