Engraving from The Illustrated Exhibitor published in June 1851. This is the original image as published. A version cleaned to remove the bleed thru text can be purchased by searching for KGJ1WH
The invention was to help his friend Louis Braille who had invented his code for the blind based on a Napoleonic military code for night writing called sonography. Braille used the machine until his death to compose letters to his Mother. It has been argued it was the first ever typewriter. As can be seen in the image it had a radial fan of letters on metal stalks that converged in the centre when pressed. Apparently when a letter embossed it also moved sideways by the space of a letter, and when it reached the end of the line it moved by the breadth of one line. Certainly sounds like one.
