Roberts 4X, In-line 4 Engine
The Roberts 4-X engine is a 2-cycle, water-cooled rotary valve engine. Its construction features the lightweight magnesium alloys Aerolight and Magnalium, resulting in an especially good power-to-weight ratio. It is among the most reliable aeronautical engines available, and has powered some of the most notable aeroplanes of the day, including Benoit, Bleriot, and Curtiss types.
This particular example was used by Harry H. Ford of Bridgeport, Conn., in his 1912 Curtiss Hydroaeroplane. Ford has been a leading aviation pioneer in Connecticut.
Gift of Harry H. Ford.
