Abstract

550,484. Variable-pitch propellers. STONE & CO., Ltd., J., and HATCHER, E. C. July, 1 1941. No..8264. [Class 114] Propeller blades, or, as shown, control blades d pivoted to the trailing edges of the main blades c, are adjusted for pitch by arms k fixed to the root ends of the blades and forked to embrace cams l secured to quadrants p actuated by the longitudinal movement of a rack q. In a modification, Fig. 6, the arms k are bent to embrace a single cam disc r formed on a nut rotated by the longitudinal movement of screw x. In both forms, the arms k may be provided with hardened bearing pieces s<SP>1</SP> for engagement with the cams.
