There were many people who had a hand in âinventingâ the vacuum cleaner. Every invention and patent has made minor improvements and has evolved into what we use today. Many people are under the assumption that H. Cecil Booth, a British engineer, was the first person to patent the vacuum cleaner in 1901.[1] The first person to patent a version of the vacuum cleaner is Daniel Hess, from West Union, Iowa, in 1860.
The carburetor was invented by an Italian, Luigi De Cristoforis, in 1876. A carburetor was developed by Enrico Bernardi at the University of Padua in 1882, for his Motrice Pia, the first petrol combustion engine (one cylinder, 121.6 cc) prototyped on 5 August 1882.A carburetor was among the early patents by Karl Benz as he developed internal combustion engines and their components.Early carburetors were the surface carburetor type, in which air is charged with fuel by being passed over the surface of gasoline.uch systems were originated by Carter Carburetor in the 1950s for the primary two Venturis of their four barrel carburetors, and step-up rods were widely used on most 1-, 2-, and 4-barrel Carter carburetors through the end of production in the 1980s.
