Hubert Cecil Booth (4 July 1871 – 14 January 1955) [1] was an English engineer, best known for having invented one of the first powered vacuum cleaners. [2] [3] [4] [5]He also designed Ferris wheels, [1] [6] suspension bridges and factories. [1]
The manual vacuum cleaner was a type of non-electric vacuum cleaner, using suction to remove dirt from carpets, being powered by human muscle, similar in use to a manual lawn mower. Its invention is dated to the second half of the 19th century, when patents were granted to inventors in the United States, Britain, France, and elsewhere.
He invented his first vacuum cleaner, called the Domestic Cyclone, in 1906, which was a hand-powered canister cleaner that used a water filtration system. His first portable vacuum cleaner for home use was manufactured and distributed by Franz Premier Electric, which was founded to produce Kirby's vacuum in 1914.
These machines are able to spray hot soapy water and then suck it back out of the fabric, removing dirt in the process. Wet vacuum cleaner have been modified by end users, adding an internally-mounted sump pump for continuous removal of liquids without having to stop to empty the tank. [25] [better source needed]
David T. Kenney (April 3, 1866 – May 26?, 1922) was an inventor with nine patents, granted between 1903 and 1913, applicable to both machine-driven and manual vacuum cleaners, dominated the vacuum cleaner industry in the United States until the 1920s.
James Murray Spangler (November 20, 1848 – January 23, 1915) was an American inventor, salesman, and janitor who invented the first commercially successful portable electric vacuum cleaner that revolutionized household carpet cleaning. His device was not the first vacuum cleaner, but it was the first that was practical for home use.
Drinker's father was railroad man and Lehigh University president Henry Sturgis Drinker; [1] his siblings included lawyer and musicologist Henry Sandwith Drinker, Jr., pathologist Cecil Kent Drinker, [2] businessman James Drinker, and biographer Catherine Drinker Bowen. [1]
In 1913 he received a professorship at the University of Freiburg. In the following six years, he invented the momentum transfer pump (molecular pump) and a mercury diffusion pump. In 1919, Gaede joined the Karlsruhe Institute of Technology as a professor of experimental physics, [2] where he worked in the following research areas: Vacuum ...
