Improved road vehicle
A patent protects the work of the inventor by excluding others from making, using, offering for sale, or selling the invention. This patent was granted to Charles Duryea on June 11, 1895, for “Improvements in Road-Vehicles” which he and his brother Frank had developed. The Duryeas produced the first successful American gasoline-powered automobile and later went on to help found the Duryea Motor Wagon Company, which produced 13 automobiles in 1896.
