Designed by famed typewriter designer Charles Spiro in 1906 and first manufactured
in 1910 by the Visigraph Typewriter Co., 37-41 West 116th St. New York, as the "Visigraph"
and later by his own C. Spiro Mfg. Co. 68-72 East 131st St. New York.
In July 1919, Spiro sold his design and tooling to Federal Adding Machine Co., 251 Fourth Avenue, New York City, NY, USA., which renamed the machine "Federal Visible".
Both the Visigraph and Federal Visible have removable and interchangeable carriage, engaged by a small lever in the rear of the machine.

|Federal Visible||1919-1921||Four row frontstroke standard.||24,59|
|1922||Hammond officially completed purchase of Federal Adding Machine Corporation and reorganizes as Hammond Typewriter Corporation with $3 million in preferred stock and $4.5 million common stock. Hammond is sued Sept. 19 for failure to actually pay for the sale from this increased capitalization. While Hammond had intended to build and market the National under the name Hammond alongside its other machines, it is unknown if that plan ever came to fruition.||82|
