Abstract

24,718. Hernaes, N. Nov. 4, 1908, [Coxvention date]. Screw propellers.- The blades are triangular, the base being connected to the boss by a narrow arm, and being at least onethird the length of the radius of the propeller. The h e i g h t of the triangle is at least two - thirds of t h e radius. The water near the boss is thus acted upon by a very small surface, and in the following zone by the widest portion of the blade.
