Adams Co

Like another builder of rotary engined road vehicles, Stephen Marius Balzer of New York, the Adams Company offered light gyrocopter engines which successfully powered experimental flying machines by Emile Berliner in 1909-1910 and J. Newton Williams in 1909. Engine production lasted longer than automobile manufacture although it is not clear when this stopped, too. The Adams Company then relied on their iron foundry and manufacture of gears, shafts and parts for power transmissions which it does until today.

When F. Oliver Farwell left the company in 1921, he had about 20 patents on his name and tried to build up a business on one he held for a novel transmission for merry-go-rounds. Later, he worked again in a gear-cutting company in Toledo, Ohio.

Adam RA-14 Loisirs

A side-by-side two seater, the RA-14 Loisirs was mainly intended for construction by amateur builders and aero clubs, using Adam-supplied parts and components. The RA-14 was also delivered complete.The RA-14 made the first flight on March 16, 1946 and this aircraft was powered by a 40 hp Train engine. The RA-14 had a fabric covered fuselage and wings and was built in several variants, with engines in the 65-90 hp power range. The type was popular in the immediate post-war years and several dozens were built.

One example of the RA-14S Loisirs was built, featuring a plywood covered fuselage and several other features of the RA-15 model. In 1957 Maranda Aircraft in Canada acquired the marketing rights for the RA-14 and also developed several improved versions. The RA-14 serving as the basis of the AMF S-14. Another homebuilt variant was available from Falconar, also in Canada.
