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.
Henry Leavitt Ellsworth
In today's world Ellsworth would be described as an early technology adapter. He became so interested, for instance, in a new-fangled invention by Samuel Morse called the telegraph that Ellsworth petitioned Congress for a $30,000 grant to test the possibilities of the technology.
