The Paterson-Francis Twin-Tractor of 1913 was a two-place open cockpit biplane. It was powered by Hall-Scott V-8 with two chain-driven props. A developed version of the 1912 Fowler-Gage, the plane’s components were designed and built in San Francisco by Francis, then shipped to Cicero IL for assembly. It crashed on its test flight and disappeared soon afterwards, either stolen or vandalized.
