Burt Typographer, 1829.
© Science Museum / Science & Society Picture Library
Replica. Patented by William Austin Burt of Detroit, Michigan, United States in 1829, this was the first writing machine to give acceptable results. A swinging arm carries a type-sector which is inked and presed down to print the required letter, after which the paper is positioned for the next letter by means of the clock dial at the end. Line spacing is achieved by moving the whole mechanism acros the top of the box. Burt's original patent model was destroyed by fire in 1836 but was reconstructed in 1893. The Typographer seen here is a replica of this.
