Booth created a large device, [11] driven by an internal combustion engine. Nicknamed the "Puffing Billy", [12] Booth's first petrol-powered, horse-drawn vacuum cleaner relied upon air drawn by a piston pump through a cloth filter. It did not contain any brushes; all the cleaning was done by suction through long tubes with nozzles on the ends.
Fluids cannot generally be pulled, so a vacuum cannot be created by suction. Suction can spread and dilute a vacuum by letting a higher pressure push fluids into it, but the vacuum has to be created first before suction can occur. The easiest way to create an artificial vacuum is to expand the volume of a container.
Wellcome V0005861 Torricelli invented the mercury barometer, recorded in the books of Camille Flammarion (1923) Torricelli's experiment was invented in Pisa in 1643 by the Italian scientist Evangelista Torricelli (1608-1647). The purpose of his experiment is to prove that the source of vacuum comes from atmospheric pressure. [1]
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 ...
In 1650 von Guericke invented the vacuum pump. [23] His model consisting of a piston and an air gun cylinder with two-way flaps designed to pull air out of whatever vessel it was connected to, and used it to investigate the properties of the vacuum in many experiments. [24] Guericke demonstrated the force of air pressure with dramatic experiments.
Sir James Dyson (born 2 May 1947) [2] is a British inventor, industrial designer, farmer, and business magnate who founded the Dyson company. [3] [4] He is best known as the inventor of the bagless vacuum cleaner, which works on the principle of cyclonic separation.
The first upright vacuum cleaner was invented in June 1908 in North Canton, Ohio by department store janitor and occasional inventor James Murray Spangler.Spangler was an asthmatic, and suspecting the carpet sweeper he was using at work was the cause of his ailment, he created a basic suction-sweeper by mounting an electric fan motor on a carpet sweeper and then adding a soap box and a broom ...
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.
