The history of the device
The first known patent for a vacuum cleaner received July 10, 1860 American Daniel Hess of Iowa. Vacuum was equipped with a rotating brush and a complex system of bellows to create suction air flow. The air flows through two water chambers to remove dust and dirt. August 30, 1901 British Huber Cecil Booth (born Hubert Cecil Booth) received a patent for an electric vacuum cleaner. He drew attention to the trains that used the device for blowing off dust from the seats and decided that it would be much more practical to suck dust. Booth has constructed a large device, known as Puffing Billy, driven by the oil first, and then an electric motor. It transported horses and parked outside the housing and carpet cleaners used a 30-meter hose runs through the window. The mechanical type vacuum cleaners is still going on to be improved. In 1905, Walter Griffiths of Birmingham created the Griffith's Improved Vacuum Apparatus for Removing Dust from Carpets, which used furs for sucking dust. His vacuum cleaner was a portable, high- quality, compact, and resembled modern vacuums. Between 1903 and 1913 years of inventor David T. Kenney from New Jersey has received nine patents for technologies related to vacuum cleaners. In 1919 he founded the Association of manufacturers of vacuum cleaners, membership in which required a license for its patents. In 1910, Fisker has patented the electric vacuum cleaner, whose name he took from the telegraph office: Nilfisk. This vacuum cleaner weighs only 17.5 kg and can be operated by one person. The company, founded by Fisker and his companion Nielsen still exists and is called the Nilfisk-Advance. For many years, vacuum cleaners remained a luxury item, but after World War II they became common in middle-class furnishings. Vacuum cleaners are becoming more common in Western countries, since there are often large carpets, but also due to much higher standards of living and consumer culture. Vacuum cleaners for cyclone principle (using centrifugal force to separate dust and particulate matter) have become popular in the 1990's, though some companies make such vacuum cleaners since 1928. Now there are many different types of vacuum cleaners. Vacuum has become a familiar thing for each house.
