The Vacuum Cleaner
Summary
The vacuum cleaner is a household appliance that cleans by suction. It is generally used on a textured surface, such as carpet, and is pushed over the surface, sucking up dust and dirt as it goes. The suction is created by an air pump, a partial vacuum; it creates a difference in pressure between the inside of the machine and the outside air and dirt and dust is taken in to the lower pressure zone. Friction on the carpet causes the dust to be removed from the carpet, or other surface.
History and Developments
The very first machine using the vacuum principle was patented by Ives W. McGaffey in 1869. His cleaner was manually powered, operated by turning a hand crank. This design made it difficult to operate, as it had to be pushed along the floor at the same time as turning the handle. There were many machines of this type shortly afterwards, with the first electrically driven version carpet sweeper' patented in 1900.
The first powered cleaner containing an inbuilt cleaner was developed my Hubert Cecil Booth. His device was a large one, driven by an oil engine. It had to be drawn by horses due to its size and the invention, patented in 1901, never really took off.
Next to come was an electric vacuum cleaner made from a box, a pillow case and a fan. It was invented by a janitor named James Murray Spangler and was the first vacuum cleaner to incorporate a rotating brush to loosen dirt and dust caught up in carpet. He patented his idea in 1908 and eventually sold it to Hoover Harness and Leather Goods Factory', which to this day remains one of the leading manufacturers of household cleaners.
Changing Designs and their Impacts on Society
Shapes of vacuum cleaners have been the main changes in design, from upright vacuums for commercial purposes to the preferred home vacuums, the canister vacuum. Other developments, such as cyclonic vacuums and robotic vacuum cleaners, have all been introduced due to the changing consumer expectations. Today, it is possible to purchase a vacuum cleaner in most colours.
His first invention was a lubricator for steam engines, U.S. 129,843, which issued on July 12, 1872. The invention allowed machines to remain in motion to be oiled; his new oiling device revolutionized the industrial machine industry.
First a historical look at one of the most prolific and ingenious engineers of all time – who never stopped working and fulfilling his dreams. Elijah McCoy (1844-1929) was an American inventor born in Colchester, Ontario, Canada, to parents who had escaped from slavery in Kentucky in 1837. McCoy was best known for his inventions of devices used to lubricate heavy machinery automatically. McCoy went to Edinburgh, Scotland, at age 15 and studied mechanical engineering for five years. When he came home he became a railroad fireman on the Michigan State Railroad. Back then steam locomotives had to stop at intervals so that the fireman could oil their pistons, levers, and connecting pins. About 1870, while living in the town of Ypsilanti, Michigan, McCoy began to experiment with automatic lubricators for steam engines.
The women were using sewing machines. These machines were invented by many different people, but the first inventor to get a patent on the machine was Ellis Howe. This patent was awarded in 1846.
a vacuum cleaner. In a resident of West Union, Iowa, called his invention a carpet sweeper, not a vacuum. This sweeper did have a rotating brush like other sweepers, however, the machine also possessed a great mechanism on top of the sweeper to generate suction. The amazing thing about his machine was that it incorporated water chambers to capture the dust and fine dirt, He states that the air is cleaned as it passes through things and gets the must little trash. There is no record that this machine was every produced because every vacuum has something that does special.
Along with Whitney's cotton gin, inventions in society came about. This was a stark contrast to pre Jacksonian rule out of which few inventions came: The decade ending in 1800 saw only 306 patents, while the decade ending in 1860 saw 26,000 patents. Elias Howe and Isaac Singer contributed to the clothing industry with their 1846 invention of the sewing machine. This contributed to northern industrialization, and when combined with the power of steam to produce an automatic sewing machine, it was capable of producing clothing on its own in large quantities with little supervision. John Deere helped to revolutionize farming once more with his invention of the steel plow in 1837. This plow enabled the "virgin soil" of Western lands to be broken, furthering agriculture. It was also light enough to be horse-drawn, which meant it was easily maneuverable. Cyrus McCormick's 1831 horse-drawn grass reaper enabled one man to do the work of five. This caused an abundance of cash crops to be produced.
The basic function of the Roomba isn’t too far from similar models or devices. Its cleaning patterns consist of zigzag motions as it moves along the edges of walls and baseboards and uses the spot cleaning mode for local
Later in his career, he made a machine that would curl hair. This device was later called a curling iron. He later patented it, making his first patented invention of two hundred seventy-one. Another invention he created was the indoor sprinkling system. This would not only put out fires, but also warn the fire department. Even with
James Paige invented the automatic Paige typesetter around 1877. The typesetter was said to have the power of four men’s jobs. It was not only going to be the greatest invention of the nineteenth century, it was going to make publishing companies a fortune by cutting down on time and initial printing costs. In 1877, Dr. George F. Hawley signed a contract with Paige to use his typesetter and the Thompson distributor, another machine that sorted printed papers, to combine them into one machine.
the world. It was invented by Eli Whitney while America was still barely 10 years old. At that time
In late 1997 a group of engineers proposed to develop a high-speed hand dryer. The research and development process would take them more than three years.
On May 13th, 1930, Jacob Schick, an american inventor and entrepreneur, invented the electric razor. This invention created a way for men and women to dispose of unwanted body hair without accidentally getting cuts, gashes, and other unwanted injuries. This invention would be highly regarded as an important invention in modern history.
Access to electricity gave Americans power to run labor-saving devices like refrigerators , washing machines ,radios ,phonographs , electric razor and iron and vacuum cleaners .These list of inventions helped shaped America in the 1920s . The first lightweight electric iron was invented by Earl Richardson . Richardson was an American businessman at the Ontario (California) Power Company .In 1905 the iron with a hot point became the first commercially successful electric laundry iron and was formally named the Hotpoint iron in 1907 . His design made the iron with more heat in the point . He had called his new company Hotpoint which he founded in 1911. The Thor washing machine was produced by Hurley Electric Laundry Equipment Company. It was the first electric washing machine sold in the United States . Alva J. Fisher was the Hurley engineer designer for the project . The Thor washing machine exploded mass marketed through America . Sales was reaching 913,000 units in 1928. Music introduced Americans to large-scale radio
Early electric vehicles may have appeared as early as 1830. Scottish inventor Robert Davidson constructed the world's first prototype electric vehicle in 1837, but historians generally credit J.K. Starley, an English inventor, and Fred M. Kimball of Boston with building the first practical electric cars in 1888. Later in the in the decade, William Morrison of Des Moines, Iowa, constructed his version of the electric vehicle in 1891. His vehicle required 24 storage battery cells, took 10 hours to charge, and could run for 13 hours. It could carry up to 12 people and had a 4-horsepower motor. His car could reach speeds up to 14 miles per hour. Morrison, however, never mass-produced his vehicle. The first commercially produced electric vehicle was the Electrobat. It was manufactured by Philadelphia-based Morris and Salom Company. In 1896, the Woods Motor Vehicle Company of Chicago became the first American manufacturer of electric cars.
Wright(Malin). It was the first machine invented to carry men, rise by its own power, fly naturally, and
Long ago, washing clothes was done through the process of rubbing sand on clothes, or by smashing the article of clothing with hard rocks. Also, by dipping clothing in water which removed excess dirt. Another way to get clothes clean long ago was, boats used to carry clothes in bags and dragged the bags in the water to clean the clothes or whatever else was in the bag. Many tried to think of simpler ways to wash clothes, but there was no troubled principle to get clothes clean. For using water to remove dirt was the base principle. Some of the first washing machines were hand operated and were wash boards. Then, in 1858 was when mechanical washing machines became introduced. This was a big step, for soon people around the world would try to keep improving this marvelous invention. Shortly after, Alva Fisher was said to have made the worlds first electric washing machine around 1907. “It was not until the modern washing machine was invented that women were freed from this hard work” ( Field Enterprises Educational Corporation 45 ). However, many ...
