PRATT'S PTEROTYPE TYPEWRITER INVENTION
In 1865, John Pratt, of Centre, Alabama, built a machine called the Pterotype ('winged type')which
appeared  in the July 6, 1867 issue of Scientific American inspired many other typewriter
inventors. A unique feature of the machine was that the typefaces were on a 'type plate',
which was moved horizontally and vertically by the keys, and a hammer struck the paper
from behind, driving it against the type. Pratt received British letter patent no.3163 on Dec. 1, 1866
and US Letter Patent No. 81000 on Aug. 11, 1868. Unable to develop it commercially,
Pratt sold the rights to James Bartlett Hammond, and many of it's features were incorporated
in the Hammond typewriter.
