Abstract

281,721. Florine, N., and Soc. Nationale pour l'Etude des Transports Aeriens. Dec. 3, 1926, [Convention date]. Screw and like propellers.-A helicopter is supported by two or more lifting screws all rotating in the same direction, the pitch of the blades being cyclically adjustable to effect lateral balance, and the pitch of each screw as a whole being adjustable. The blades 10, Figs. 5 and 6, of the lifting screws are pivoted in arms 8'on a casing 7 rotating about a column 3 and have arms 12 forming part of parallel linkages having rollers 14 bearing against a plate 16 pivoted to a sleeve 18 capable of sliding without rotation upon the column 3. Eyes 19 on the plate 16 are connected through links 20, levers 21 and links 23 to arms 24 on Longitudinal shafts by turning which in the same direction or in opposite directions the plate 16 is moved bodily or tilted laterally to vary the pitch of the blades as a whole or cyclically.
