The Eureka Typewriter
The Eureka Typewriter was produced ca.1885 by the Eureka Typewriter Company. The company was located at 23 Duane St. in New York, NY though it was incorporated in the State of New Jersey. I am unsure if it was ever awarded a patent even though the typewriter itself was marked with "Pat. Apl'd For." It consisted of a wood base with pair of rails and a round, spring-loaded index with rubber type. Overall, it's very crude. The Eureka measured just 9-1/2" long by 3" wide and it was sold predominantly through mail order. The Eureka, along with others like it, was part of a scam that offered users money for typed papers. First, of course, one had to buy the machine itself for $2. Because of how crudely the typewriter was constructed, it proved impossible to type quickly and accurately with. It would take a lifetime for even the most proficient users to produce enough text to cover just the initial cost of the typewriter. The Eureka, and others like it, were officially forced to cease their mail order scam in July of 1903 but I've found no proof of any marketing or selling of the Eureka outside of the 1880's.
