The Hartford typewriter was invented by John M. Fairfield who also -had a hand in developing the Dart Marking -Machine, an index typewriter. Before being involved with these two typewriters, Fairfield was superintendent of The American Writing Machine Company of Hartford, which produced layer models of the Caligraph. The Hartford Typewriter Company, also of Hartford, obviously, produced the aptly named machine on this page. Ultimately, three models produced. Nos. 1& 2 had full (double) keyboards while the No.3 had a standard 4-row one. After the company relocated to Cleveland, Ohio, the name of the typewriter was changed to the Cleveland. The most peculiar attribute of these typewriters was that they had just three feet. Two on the front and one centered in in the back.
