On 25 October 1907 Watson applied for a patent that, "...relates to flying machines, the object being to raise and propel a machine through the air without aerostats." Accepted in its entirety nearly a year later, Patent No.23,553 of 1907, titled "Watson's Flying Machines" comprises eight pages of descriptions of an indigenous rotary-wing means of creating lift and five illustrations to which the description pages are keyed. These show different configurations of aircraft using the same rotary aerofoil devices that resembled the sheathing mechanism of a combine harvester. No evidence survives to suggest Watson began constructing any of the bizarre creations in the patent.
