Office in Washington, D.C. on March 9 of that year according to a typewritten letter to his wife of March 13, 1830. The typeface letters for this Patent Office model was obtained from a Mr. White of New York, a typeface founder. Even though a neat-looking letter could be typed on Burt's "typographer", the basic goal to speed up correspondence was not accomplished, as his machine was very slow in typing. Because of this, the machine could not get marketed. Burt lost interest in it and sold his rights to one Cyrus Spalding for $75 on March 17, 1830 with suggested improvements. Ultimately he did not have any further luck in marketing the typewriter. References Sources American inventions Typewriters
