Abstract

1,205,246. Controlling variable pitch propellers. A. FEROY. 29 Sept., 1967 [17 Oct., 1966], No. 44486/67. Heading B7V. In a controllable pitch propeller having a hub 10 and radial blades such as 15, blade root 14 of each blade has serrations 17 on its inner face and a mechanism rotates the roots and blades to control the pitch forward, neutral or reverse; the mechanism comprising an axially movable control rod 24, a set of blocks 22 axially movable with the control rod, serrations 21 on the outer face of each block 22, a set of floating or coupling plates 19, circular arc serrations 18 on one side of each floating plate and straight serrations 17 on the other side, the floating plate serrations operably meshing with the corresponding serrations, on the blade roots and on the axially movable blocks 22.
