    There has been primitive elevators since 3 century BC.  In 1823, two architects Burton and Hormer built an "ascending room" as they called it, this crude elevator was used to lift paying tourists to a platform for a panorama view of London. In 1835, architects Frost and Stutt built the "Teagle", a belt-driven, counter-weighted, and steam-driven lift was developed in England.   In 1846, Sir William Armstrong introduced the hydraulic crane, and in the early 1870s, hydraulic machines began to replace the steam-powered elevator.  In 1853, American inventor Elisha Otis demonstrated a freight elevator equipped with a safety device to prevent falling in case a supporting cable should break. This increased public confidence in such devices. In 1853, Elisha Otis established a company for manufacturing elevators and patented (1861) a steam elevator. While, Elisha Graves Otis did not actually invent the first elevator, he did invent the brake used in modern elevators, and his brakes made skyscrapers a practical reality.
    In 1857, Elisha Otis and the Otis Elevator Company began manufacturing passenger elevators. A steam-powered passenger elevator was installed by the Otis Brothers in a five-story department store owned by E.W Haughtwhat & Company of Manhattan. It was the first public elevator.  Electric elevators came into to use toward the end of the 19th century. The first one was built by the German inventor Werner von Siemens in 1880.  Then, Alexander Miles patented an electric elevator (U.S. pat#371,207) on October 11, 1887.

    2. The lawn mower was invented in 1830 by Edwin Beard Budding, an engineer from Stroud, Gloucestershire, England.

    3.  On July 17, 1902, Willis Haviland Carrier designed the first modern air-conditioning system.  Frederick Jones was born 1893 so that would make him only 9 yrs old at the time the air conditioner was built.

    4.  Sir Joseph Swann of England and Thomas Edison both invented the first electric incandescent lamps during the 1870s.

    5. September 4, 1849 that the first street sweeper was patented by C.S. Bishop of Easton, Pennsylvania. It was a towed attachment fitted with a rotating brush wheel. The brush swept refuse onto a conveyor that lifted the material into a holding bucket.

    6.  Urban development got a major boost in 1887 when inventor Frank Julian Sprague developed the world's first successful electric street railway system.  

    Maybe you should have read all that was on snopes and realize all those that was said was not true.  Try to do research for once instead.
