Escalator was patented in 1892 by Jesse Reno of New York City. He used his escalator as a ride at Coney Island. Later, by about 1910, the escalator was developed as a mode of moving people.
First roller coaster opened in 1884. The “Gravity Pleasure Switchback Railway” of Coney Island dropped 50 feet, and the mechanism traveled six miles per hour. It cost a nickel to ride.
