Abstract: 448,081. Screw propellers. SOC. D'ETUDES POUR L'AVIATION, 23, Rue Marie-Debos, Montrouge, Seine, France. Oct. 29,1935, No. 29877. Convention date, May 31. [Class 114] The blades of a variable-pitch screw propeller are adjusted by a wind wheel coaxial therewith the wheel having the blades of fixed pitch and operating by its aerodynamic couple through gearing to adjust the main blades. The blade or blades 1 of a wind wheel are mounted on a boss 25 which is frictionally driven by the propeller shaft 19. The boss is formed with a spur wheel 26 which engages spur wheels 27 on shaft 28 carrying in addition a worm wheel 30 engaging a further wheel 31 and the shaft 33. This in turn gears with a spur pinion 34 rotation of which moves a screw member 37 axially, and by its connection with the sliding sleeve 40 acts upon an eccentric pin 41 at the base of each blade to adjust the pitch. When the propeller is running at the correct speed there is no relative movement of the parts, and on a change of speed up or down the aerodynamic couple blade 1 produces a motion of the hub 25 relative to the shaft against the action of frictional driving washers 24, and thus produces a pitch change.
