Abstract

14,409. Ruthenberg, H. June 19. [Addition to 13,791/09.] Screw propellers.-In propellers of the type described in the parent Specification, the blades instead of being flat are substantially helical. Figs. 1 and 2 show a four-bladed propeller mounted in a rigid frame. The spokes d, e, f, g, arranged at right-angles to each other, are secured to the nave b ; while the spokes h, i, k, l, also at right-angles to each other, are secured to the nave c and arranged at angles of 45 degrees with the spokes d, e, f, g. Instead of the parallel rings m, n, polygonal frames may be used.
