Abstract
323,828. Caldwell, F. W. Oct. 19, 1928. Addition to 305,454. Screw propellers.-In screw propellers with blades mounted on sockets on the boss as in the parent Specification the socket is tapered and the blades are held by a common piece tending to force them on the sockets. The blade a is tapered at the root b and fits over a socket e. Half couplings i are employed the edges m of which take over shoulders g on the blades and hold them against centrifugal force, and the two halves are held together by bolts.
