Abstract

264,992. Short, H. O. Jan. 11, 1926. Screw propellers.-In airscrews of the type in which the blades are hinged to the boss, the hinges are inclined fore and aft and are contained in planes which intersect the axis of the shaft obliquely. The blades are able to assume various positions automatically under the joint influence of centrifugal force and thrust. The boss A has two radial oblique arms B, C, and the blades D are secured thereto by pins E passing through hinge members B<1>, D', such pins being obliquely disposed. The arms B, C may be of any length, from being mere flanges up to constituting the major part of the blade. The blade may be formed with more than one hinged section.
