Transcript of Elevators

By Justin Sankar
Cameron Masker The History of Elevators From the mid-19th century, elevators were mostly steam operated and used for transporting materials in factories, mines and warehouses.
In 1823, two architects, Burton and Homer, built what they called the "ascending room".
In 1835, Frost and Strutt built the "Teagle" which was a counter-weighted steam powered elevator Why were improvements made? The first elevators were built out of wood and were moved by a counterweighted hand crank
It was later redesigned using iron and a steam powered counter-weight
Modern elevators use high strenght steel and electric motors to make them more energy efficient and safe Designs and Inovations of the Elevator What impacts does this have on society? Early History... Who uses these product? Patents Elevators are used in buildings that have multiple floors that require a lift system to get people up and down. They are also used to help people go up floors who are physically unable to do so. Improvements have been made to the elevator over time to increase reliability and safety to the user. The elevator has also been advanced to make tall buildings possible and to increase their strength. Elevators have allowed buildings such as skyscrapers to be possible. This invention has allowed city skylines and the idea of what is consider to be a modern city possible. Discipline of Engineering Related To The Elevator Timeline of The Elevator Civil Engineering
Electrical Engineering
Mechanical Engineering In the year 1743, when the modern elevator was first invented, many different people have patented their own innovation to improve the elevator. People have patented things such as the counterweight and lift designs, electical system and the cars themselves. 1743

Shipping Elevators Period 8 An example of a possible change that can be made to the elevator would be somehow increasing the speed and making it more energy efficient. Changes Modern Day Elevator 1852
