Abstract

9582. Simon, F. April 23. [Addition to 19,997/11.] Screw and like propellers. -Comprises the curving-over of the casing c at each blade lip b to form a deflecting-lip c', and also consists in joining the narrow part e of the casing with the enlarged part d more gradually, the angle at f being obtuse, With the curved lips and the arrangement of two propellers on one shaft, the after propeller is smaller than the forward one.
