AIRSHIP PROPELLER Application filed May 15, 1930. Serial No. 452,618.
This invention relates to air-ship propelshaft 14 in a circular motion transverse to lers and particularly to propellers having a the axis of the said main shaft. The bevel compound form of motion in which the blades pinions, being in mesh with the annular gear, rotate n the shaft to which they are atare caused to revolve and this imparts a rotached while the said shaft swings transtating motion to the blades 21. Thus, the 5:) versely on the drive shaft of the ship, the blades while being swung in a circle about the object being a combined stabilizing and promain shaft axis, are also rotated at right pelling force. angles thereto by the said level pinions. This Further objects are, to provide simple and compounds the propelling and stabilizing eiiicient means to produce the above described forces and greatly improves the efficiency of effect, and a form of mechanism which may the ship. be easily and economically constructed.
