In 1892, Jesse Wilford Reno patented a moving conveyor designed to transport people between different levels. His invention was first exhibited as an amusement ride at Coney Island, attracting around 75,000 visitors in two weeks. The conveyor consisted of metal boards and operated at a 25-degree gradient, differing from modern escalators. Although seen as an entertainment novelty, it laid the groundwork for future escalator development.
