Abstract

474,512. Oscillating - vane propellers. CHIBA, S. March 9, 1937, No. 6959. [Class 114] Oscillating-vane propellers are provided with a number of flexible plates. In one form, plates 9, 10, 11 and 12 are pivoted at their forward ends on pins supported in horizontal arms 3, 4 carried by a vertical stem 2 which is adapted to be oscillated by an arm 13. As the frame is oscillated to and fro these vanes take up independently curved shapes for the purpose of assisting the propulsive effort. The arms 3, 4 may themselves be slightly flexible so that they also take up a curved shape under pressure. In an alternative form, the depending stem 2 carries a single horizontal arm 3 and the pivots of the blades are formed above and below such arm so that the blades are each in duplicate. More than one such installation may be fitted to a boat.
