Abstract

485,982. Screw propellers. VEREINIGTE DEUTSCHE METALLWERKE AKT.-GES. Oct. 21, 1937, No. 28690. Convention date, Jan. 6. [Class 114] A variable pitch screw propeller, wherein the blade root is screwed into a threaded sleeve, the latter at its base, has secured thereto a flanged annular member, the sleeve portion of which is of smaller diameter than the root carrying the thread and acts as a journal for a foot bearing. The blade k is screwed at its root m and has secured thereto a sleeve n which carries a worm-wheel o for the pitchactuating gear, and also a flange for supporting the thrust race i. At its base, there is secured by screws u a flanged member t the sleeve portion s of which forms a support for a foot bearing r. A hard sleeve x may be disposed between the blade root extension and the sleeve s.
