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:"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 proprietary with six cylinders of 3.2 L (3243 cc/197 in3) appeared in 1923, and a Lycoming eight-cylinder was offered beginning in 1924.
Final production
By 1924, Apperson and Haynes were both losing sales; a rumored remarriage came to naught, and Apperson folded for good despite the introduction of four-wheel brakes on the 1926 models.
