An escalator is a conveyor type transport device that moves people. It is a moving staircase with steps that move up or down using a conveyor belt and tracks keeping each step horizontal for the passenger. However, the escalator began as an amusement and not as a practical transport. The first patent relating to an escalator-like machine was granted in 1859 to a Massachusetts man for a steam driven unit. On March 15 1892, Jesse Reno patented his moving stairs or inclined elevator as he called it. In 1895, Jesse Reno created a new novelty ride at Coney Island from his patented design, a moving stairway that elevated passengers on a conveyor belt at a 25 degree angle.

"In the United States escalator accidents are fairly common. Each year approximately 10,000 people are sent to the emergency room due to accidents involving escalators. When taken in context with the millions of escalators in use along with the volume of passengers they move each year, this may not be necessarily a large percentage."
Escalaphodia is the fear of escalators.
