==Roadplane models introduced== In 1916 the company announced production of the "Roadplane" six and eights. The term "Roadplane" did not refer to a specific model but was a marketing concept devised by Elmer Apperson that was applied to the "Chummy Roadster" and the "Touring" car. Elmer took the unusual step of patenting the "Chummy Roadster" design (see:[https://patents.google.com/patent/USD48359 "U.S. Patent 48359"]). The "Silver-Apperson", designed by Conover T. Silver, was launched in 1917; the model was known as the "Anniversary" after 1919. A sedan [[Property|proprietary]] with six cylinders of 3.2 L (3243 cc/197 in<sup>3</sup>) appeared in 1923, and a [[Lycoming Engines|Lycoming]] eight-cylinder was offered beginning in 1924.
