Abstract

545,197. Screw propellers. BERLINER, H. A. Nov. 12, 1940, No. 16414. [Class 114] The blade 10 of an airscrew or other propeller is connnected to a ferrule 18 by a tapering screw-thread 12 having short faces 14 normal to the axis, and long, inclined faces 16 which converge towards the tip of the blade. The arrangement causes the connection to tighten under centrifugal force, and distributes the stress. The ferrule may be rigidly mounted in the hub, or may be rotatably mounted to permit pitch-change.
