How Scientists Use Notebooks Benjamin Franklin’s three wheel clock sketches Franklin invented a 24-hour, three-wheel clock that was much simpler than most clock designs of the time. Franklin's clock, like others from that period, only had one hand. Minute hands were not added to clocks until later. Franklin biographer Carl Van Doren describes this invention as "a curious clock, economical but not quite practical." In 1758, Franklin's friend, James Ferguson, improved the clock, much to Franklin's pleasure.
