Pivoting hoods enclosing propellers; propeller blades inclined to cause some upward motion; steering wheel attached to pulleys; envisioned (and even illustrated) for either airplane or LTA vessels
- From the spec, paraphrased: Moving hoods around the propellers will channel airflow to direct the airship up, down, forward, or backward. The invention enables the propeller blades to bend to generate a downward thrust as the propellers are rotated, and thus lift, push, steering and gyroscopic action. It is designed for aeroplanes but it may be used on dirigible balloons too.
- Tech class CPC B64C39/005: Aircraft not otherwise provided for with wings, paddle wheels, bladed wheels, moving or rotating in relation to the fuselage about a horizontal transversal axis
- Inventor location: New Westminster, British Columbia, Canada
- Title on the patent spec itself: Improvements in propelling and steering device for airships
- French title: DISPOSITIF DE PROPULSION ET DE GOUVERNE D'AEROPLANES
