In 1812, Charles Redheffer, in Philadelphia, claimed to have developed a "generator" that could power other machines. The machine was open for viewing in Philadelphia, where Redheffer raised large amount of money from the admission fee. Redheffer moved his machine to New York, after his cover was blown in Philadelphia, while applying for government funding. It was there that Robert Fulton exposed Redheffer's schemes during an exposition of the device in New York City (1813). Removing some concealing wooden strips, Fulton found a catgut belt drive went through a wall to an attic. In the attic, a man was turning a crank to power the device.
