Definition of the word escalator

The word "escalator" is derived from the combination of two words: "escalator" and "ator." The first part, "escalator," comes from the French word "escalier," which means "stairs." In 1859, Richard Sorby, an English engineer, patented a moving staircase system called the "locomotive stairway" or the "inclined lift," which aimed to move people from one level to another in a similar fashion to an elevator. However, this invention was not very successful, and it was not until the 19th century that the modern escalator was invented by the American inventor, Jesse W. Reno. Reno, who worked for the Otis Elevator Company, came up with the escalator concept in 1897. In 1899, he patented the idea of an escalator consisting of a moving staircase equipped with individually motorized steps. Reno's design, which is essentially the same as the escalators we have today, was aimed at facilitating the movement of personnel and goods more efficiently than traditional stairs. The second part of the term, "ator," is derived from the Latin word "ator," which means "one who causes to do." In this case, it refers to the mechanism that causes the escalator to move, i.e., the electric motor, conveyor chain, and other mechanical components. The term "escalator" was officially coined in 1901 and was registered as a trademark by the Otis Elevator Company. Today, the term "escalator" is commonly used to refer to the moving staircase systems that have revolutionized the way people move between different floors of buildings.
