FRIDAY, APRIL 12: PORTABLE TYPEWRITERProfile America —
Friday, April 12th.
On this date in 1892, the first U.S. patent for a truly portable typewriter was issued to
George C. Blickensderfer of
Stamford, Connecticut for a "type writing machine." The machine worked on the principle of a revolving type wheel, a precursor to the type ball of 1970s typewriters. The wheel reduced the number of moving parts from 2,500 to 250, improving reliability and reducing the weight by one-fourth. The Blickensderfer Manufacturing Company eventually became one of the world's largest typewriter manufacturers in a crowded field. In 1900, U.S. manufacturers shipped 145,000 typewriters. 1967 was the peak year with nearly 2 million shipped.
