The Improved Elevator of Alexander Miles. Important Innovations and Inventions, Past and Present. This design was impractical for very tall buildings, although it became popular in mansions because it could operate off the public water system. Another elevator design and the one found most often today in passenger elevators uses a cable system, in which ropes raise and lower the car by means of a pulley and gear system.

A counterweight, raised and lowered at the same time as the car, works like a seesaw and helps to conserve energy. These types of elevators are easier to control, and buildings that have them don't need the extra room required by hydraulic systems. By the s, these types of elevators were powered by water pressure or steam, but they still weren't very common.

Read on to find out why -- and how the person who solved the problem may or may not be considered the inventor of the elevator.

At the time, elevators that operated on a cable system were considered unreliable and dangerous, because, if the ropes broke, the elevator plummeted to the bottom. Freight could be damaged, but, more importantly, passengers were often killed by the fall. The person who found a solution to this problem revolutionized the concept of the elevator.

But was it Elisha Otis, or Otis Tufts? While working in a factory in , Elisha Otis and his sons came up with an elevator design that employed a safety device. A wooden frame at the top of the platform would snap out against the sides of the elevator shaft if the ropes broke, essentially functioning as a brake.

Otis called it the "safety hoist" and dramatically demonstrated this design at the New York World's Fair. He rode the platform high into the air and then had the rope cut, but, thanks to the brake, it only fell a few inches before stopping. Otis founded an elevator company, Otis Brothers, which installed the first public elevator in a five-story New York department store in Electric elevators came about in the s.

This means that Elisha Otis is the inventor of the modern passenger elevator, right? It depends on who you ask. Until the World's Fair demonstration, Otis hadn't had much luck selling elevators, and his initial elevator patent in was for a freight elevator -- the open platform kind -- not an enclosed passenger one.

For this reason, some think of another Otis, Otis Tufts, as the actual inventor of the modern passenger elevator. Two years before Elisha Otis, Tufts patented an elevator design that had benches inside an enclosed car, with doors that opened and closed automatically. There's a key reason why Elisha Otis gets the credit and not Tufts. In , an electric elevator with automatic doors that would close off the elevator shaft was patented.

This invention made elevators safer. Many changes in elevator design and installation was made by the great advances in electronic systems during World War II. Space elevators use the same concept of classic elevator.

They will be used to transport people to space station. This concept theoretically can considerably reduce the cost for putting a person into space.

Today, modern commercial buildings commonly have multiple elevators with a unified control system. In addition, all modern elevators have special override controls to make elevators go directly to a specific floor without intermediate stops. The ancient Greeks made first elevators, by using pulleys and winches.
