Samuel Morse
In addition to the telegraph, Morse invented a marble-cutting machine that could carve three-dimensional sculptures in marble or stone. He could not patent it, however, because of an existing 1820 Thomas Blanchard design.
Printing telegraph
Printing Telegraphs were quite temperamental and suffered frequent breakdowns. Transmission speed was also much slower than the Morse system. The complexity of the original House device meant that production was limited. An improved version was designed by George Phelps. The Globotype was invented by David McCallum as a response to problems with the printing telegraph.
