Abstract

101,425. Percevaut, E. J. M. July 22. 1914, [Convention date]. Screw and like propellers. Each blade of a screw propeller, suitable for use in air or water, comprises a central plate A having a vertical angle A<1> of 45 degrees, and wing-plates B, C bent at an angle of 22¢ degrees in opposite directions, as shown in Fig. 2. The angles adjacent to the angle A' are each 45 degrees. The boss H is polygonal, the blades being secured to alternate faces, as shown in Fig. 2.
