Abstract

124,647. Ryan, J. C. June 17, 1918. Screw propellers.-The blades mounted on the hollow shaft 1 and which are approximately of semicircular form overlap and have their forward ends so arranged as to meet the tail ends of the preceding pair at an intersecting angle, as shown, the object being to cause the blades to retain a constant grip on the water.
