In 1860 a manual vacuum cleaner was invented by Daniel Hess of West Union, Iowa. Called a "carpet sweeper", it gathered dust with a rotating brush and had a bellows for generating suction. [4] [5] Another early model (1869) was the "Whirlwind", invented in Chicago in 1868 by Ives W. McGaffey. The bulky device worked with a belt driven fan ...
The first artificial vacuum had been produced a few years earlier by Evangelista Torricelli and inspired Guericke to design the world's first vacuum pump, which consisted of a piston and cylinder with one-way flap valves. The hemispheres became popular in physics lectures as an illustration of the strength of air pressure, and are still used in ...
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.
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.
A portrait of William Shakespeare and a copy of a speech from "A Midsummer Night's Dream" were sent to the edge of space as part of a short film series marking 400 years since the first volume of ...
Kenney's first vacuum cleaner installation was in the building of Henry Clay Frick in Pittsburgh in 1902. Its stationary 4,000 lb. steam engine powered pipes and hoses reaching into all parts of the building. In 1906 his company claimed to have installed electric vacuum cleaning systems in the White House, the Times building, and elsewhere.
The steam digester or bone digester (also known as Papin’s digester) is a high-pressure cooker invented by French physicist Denis Papin in 1679. It is a device for extracting fats from bones in a high-pressure steam environment, which also renders them brittle enough to be easily ground into bone meal .
