Patent US-1918-1285479
Tilted propellers. Helicopter? Hybrid?
From google patents: "My invention relates to a new and useful improvement in airships, and has for an object. to provide an airship wherein the as forward propelling means but may be used to drive the air ship directly upward, the machine remaining in a horizontal position. Still another object of my invention is to so construct the air ship that it will be possible to go at a very slow speed when in the air, which is made possible by so providing the propellers that they may be set at an angle Where no propelling motion is given to the said air ship. Still another object of my invention is to so arrange the propellers that if desired they may be tilted at an angle to propel the machine, or on the other hand if desired they may be tilted in the opposite direction to drive the machine in a rearward direction. Still another object of my invention is to so construct the air ship that by tilting the propellers at a certain angle on the one side and the propellers on the opposite side at an opposite angle the air ship will be guided in its flight without the use of rudders."
