Abstract

172,229. Almonacid, V. A. Dec. 24, 1920. Driving -- arrangements for screw propellers; shafts, arrangement of. - Two or more airscrews are driven by the same shaft in the same direction at progressively increased speeds. With two screws, the screw a is driven directly by the engine shaft d and the second screw b is driven through a train of gearing c and hollow propeller shaft at double the speed of the screws.
