Fact 1: Who invented the Elevator? The first safety brake for the Elevator was invented by Elisha Otis in 1852 during the Second US Industrial Revolution era of inventions (1850 - 1914) which was a advancement in the area of Building and Construction.
Fact 2: Who invented the Elevator? The ancient Greek mathematician, engineer and inventor Archimedes of Syracuse built the first known elevator in 236 BC.
Fact 3: Who invented the Elevator? The primitive elevator invented by Archimedes was operated using a system of levers and pulleys by hoisting hemp ropes that were wound around a drum with two weights at its end and rotated by manpower applied to a capstan.
Fact 4: Who invented the Elevator? The Romans used the invention of the ancient Greek elevator to enhance the 'entertainment' at the Roman Coliseum. Elevators, winches and pulleys were used to raise and lower scenery and props from the Hypogeum, the vast network of rooms, cells, tunnels and passages under the Roman Colosseum. Vertical shafts containing 24 elevator cages operated by ropes, pulleys and slaves led directly to the arena providing instant access for fast changes to scenery, animals, convicts and gladiators.
Fact 5: Who invented the Elevator? The Romans also used winch systems to construct the numerous Limes watchtowers as frontier (limes) fortifications that served as boundaries to ancient Roman provinces against Germanic tribes
Fact 6: Who invented the Elevator? The ancient types of elevator were also used in Europe during the Medieval period. Fortified castles and isolated mountain monasteries used winch systems to access elevated entrances that were not accessible from ground level.
Fact 7: Who invented the Elevator? An early elevator called a "flying chair" was designed in 1743 for the French King Louis XV and installed at the palace of Versailles. The flying chair, operated by counterweights and pulleys was designed by Blaise-Henri Arnoult. The flying chair consisted of a small cabinet through which a rope hung by which the occupant could pull the rope to either lower or raise the chair.
Fact 8: Who invented the Elevator? The Industrial Revolution (1850 - 1914) saw the introduction of the hydraulic and steam powered elevator engines. The hydraulic and steam elevator combinations of levers, counterweights, cranks, wheels, windlass, wedges, pulleys, block and rope, primarily to lift materials. The hydraulic elevators operated on a principle that water pump increased the pressure of the main plunger which pushed freight compartment upwards.
Fact 9: Who invented the Elevator? The industrialization and rapid urbanization of America led to the building of taller buildings in cities. These taller buildings were made from fire-proof, iron framed structures with deep foundations.
Fact 10: Who invented the Elevator? The hydraulic elevator was not a practical solution for tall buildings. The main plunger used to operate hydraulic elevators required a pit below it that had to be as deep as the building was tall! The problem was solved in 1850 by Henry Waterman of New York. Henry Waterman invented a rope-geared elevator with multiple pulleys
Fact 11: Who invented the Elevator? The Henry Waterman standing rope elevator resolved the problem of the plunger but created yet another huge problem - if the rope were to snap while people were on the elevator they would fall to their death.
Fact 11: Who invented the Elevator? George H. Fox introduced the use of wire rope, invented by John Roebling in 1841, to replace the hemp rope that had been used in the first Henry Waterman standing rope elevator elevators. But deep concerns over the safety of people using elevators continued, the lift still needed to be stopped safely.
Fact 12: Who invented the Elevator? The man who resolved this problem was Elisha Graves Otis who, in 1852, invented the safety device that prevented the elevator cabin from falling if the main cable broke. The Elisha Otis invention of the safety elevator enabled the development of the new buildings called 'Skyscrapers'.
Fact 13: Who invented the Elevator? The inventor of the first safety
brake for the Elevator, Elisha Otis, was born on August 3, 1811 in Halifax, Vermont, United States and died on April 8, 1861. Elisha Otis is not only famous as the American inventor of the
safety brake of the Elevator but also as a industrialist, designer and founder
of the Otis Elevator Company.
Fact 16: Who invented the Elevator? It was the responsibility of Elisha Otis to install one of the Henry Waterman standing rope elevators to facilitate the easy movement of the firm's bedsteads.
Fact 17: Who invented the Elevator? After identifying the major safety
problem of using elevators to transport people he set about improving the
elevator design, focusing on safety.
Fact 19: Who invented the Elevator? Elisha Otis left the bedstead factory to work on his invention. On September 20, 1853 Elisha Otis made his first sale and the Otis Elevator Company was launched.
Fact 20: Who invented the Elevator? Elisha Otis was a real showman and put this extrovert side of his character to good use when promoting his invention of the safety brake for Elevators at the 1854 World’s Fair in New York City’s Crystal Palace.
Fact 21: Who invented the Elevator? Elisha Otis put on a daring public display at the 1854 World’s Fair in New York City’s Crystal Palace. His elevator was displayed at the fair. Elisha Otis stood at the top of the open shaft, its supporting rope was cut and then Otis displayed himself to the shocked crowd standing in the elevator, safe and sound.
Fact 22: Who invented the Elevator? Orders for the safety elevator came flooding in. Elisha Otis improved his invention still further when he a three-way steam valve engine that provided more precise control of elevators in motion. On March 23, 1857 the first commercial passenger elevator was installed in the E.V. Haughwout and Company department store at Broadway and Broome Street in New York City and the first Otis steam elevators were installed in 1859.
Fact 23: Who invented the Elevator? Elisha Otis died from diphtheria on April 8, 1861. His company was then run by his sons Charles and Norton who built it into a global giant, installing a safety elevator in Paris's Eiffel Tower in 1889 and another in the Washington Monument in 1890. In 1913, the Otis Company installed an elevator inside the 60-storey Woolworth Building in New York City, at that time the world's tallest building.
Fact 24: Who invented the Elevator? In 1887 an African-American inventor called Alexander Miles (May 18, 1838 - May 7, 1918) invented an automatically opening and closing elevator door design. Alexander Miles was granted U.S. Patent number 371,207, on October 11, 1887.
Fact 25: Who invented the Elevator? Toward the end of 19th century several key discoveries regarding the use of electricity. In 1880 German inventor Werner von Siemens harnessed the power of electricity and built first electric elevator. In 1903 the gearless traction elevator was introduced and in 1922 Westinghouse launched the fastest elevators that had automatic landing mechanism with a speed of 420 meters/minute.
Impact: How did the Elevator impact the world? The invention of the safety Elevator shaped the architecture and skylines of the cities in America and across the world.
