Elevator History
An elevator is a mechanism for moving people and freight from level to level in a building or any other structure. The first elevator-like structure was built in 236 BC by the
Archimeds. This construction was a hoist operated by ropes and pulleys. However, the first pragmatic elevator was not developed until the 19th century. Though sensible, this elevator has been modified many times throughout the course of history and is still updated with all of the new advancements in math and technology. From the start of the production of elevators through today, there have been numerous and boundless improvements made on their structure and how they operate: all due to the advancement of mathematics and technology. The first elevator developed was known as a manual elevator. This system of elevators used "relay logic". Relay logic was a simple wiring based on circuits. This type of elevator did not transfer people from one level to another, only cargo. ***** The second type of elevators was developed in the 1800s. These elevators were powered by steam. At first, these elevators were used solely to transport freight in factories and ore in mines. Unfortunately, these elevators required a safety device to restrain the elevator from dropping if it's supporting cable broke, and this had not been invented yet. Eventually, this necessity was discerned and acted upon. In 1852, Elisha
Graves Otis designed the first safety contrivance for elevators. This device was a system involving spring-operated cams that affianced the guide rails in the elevator shaft when the cable broke. This secured the elevator from subsiding which enabled steam powered elevators to be used for transporting people along with cargo. This new use was caused by the precautions taken in improving the safety of steam powered elevators. It was first used for people in 1857 in New York's own Haughwout' department store. This edifice was driven by steam power: unlike
