Escalators

BY: DAVID ENCARNACION

HISTORY Escalator are a type transportation device that moves people from one level to another without human physical movement. It’s a moving staircase with steps that move up or down different levels, that use a conveyor belt and track which keep the step horizontal for the pedestrians. Thus the escalator began as an amusement and not as a transportation system that is being use today. 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.
