Basic demo of a rare 1953 music typewriter. The Keaton Music Typewriter looked very different from a regular typewriter. It had two keyboards, one which was moveable and one stationary.
The Keaton Music Typewriter was first patented in 1936 (14 keys) by Robert H. Keaton from San Francisco, California. Another patent was taken out in 1953 (33 keys) which included improvements to the machine. The machine types on a sheet of paper lying flat under the typing mechanism.
