Abstract: An aeroplane propeller assembly comprising a pair of hub members made of nylon with glass fibers interspersed therein forming an undulant gripping surface for clamping the root ends of wooden propeller blades and embedding the raised areas of the hub surfaces into the wood to obtain a firm and shakeproof purchase thereon as the hub members are bolted to each other and to the blades. The hub members are in the form of discs and have root-end-confining pockets formed to clamp the end portions and hold them under compression tightly within the pockets, each pocket having sharp pins molded therein and strategically located not only to pierce into the wood but also to swell the wood and contour it against the enclosing surfaces of the pocket. The propeller blade root ends are adapted to be cut at different angles to obtain different pitch upon being fitted into the same pockets.
