John A. Hubbard (1820-1893) of West Houlton worked as a millwright, farmer, and cabinetmaker. He invented this improved design for a horizontal windmill in 1865 and registered his invention with the U.S. Patent office.

Hubbard’s invention includes a second wheel to help regulate the speed at which the mill turns. This demonstration model includes a reciprocating saw.

No record exists to suggest whether the full-size windmill was built.
