Typewriter Fox
This typewriter is the Fox model 4, from 1901 made in Grand Rapids, Michigan, in USA.
The name “Fox” evokes speed and rapidity, but actually the name derives from the inventor and owner of the company, William Ross Fox. At those times, most typewriters had the particularity that the secretaries could not see what they wrote. It was the so-called blind writing.
The mechanisms are simpler, but the disadvantage is that to view their work, the secretaries had to stop typing and lift up the carriage, slowing the typing process.
The typing bars are under the roller, hit the roller at the bottom, and moves from bottom to top, hidden from the typist's view.
