One of his many publications appears to concern the subject of aeronautics. Entitled "On aerial locomotion," the document was published in 1864, four years before Boulton received his aileron patent. It is within this publication that Boulton probably first coined the term aileron, meaning "little wing," and described how such a device could be used to perform the function to which the modern aileron was later applied by Frenchman Henry Farman.
1868 He patented a system of lateral flight control involving what would later be called ailerons
