June 8 - Ives McGaffey patents the vacuum cleaner, a "sweeping machine" in 1869. This was the first patent for a device that cleaned rugs.
Hubert Cecil Booth, a British engineer, received a British patent for a vacuum cleaner on August 30th 1901 and took the form of a large, horse-drawn, petrol-driven unit which was parked outside the building to be cleaned with long hoses being fed through the windows. As Hubert Booth, demonstrated his vacuuming device in a restaurant in 1901, two Americans introduced variations on the same theme. Corinne Dufour invented a device that sucked dust into a wet sponge. David E. Kenney's huge machine was installed in the cellar and connected to a network of pipes leading to each room in the house. A corps of cleaners moved the machine from house to house.
In 1907, James Murray Spangler, a janitor in a Canton, Ohio department store, deduced that the carpet sweeper he used was the source of his cough. He tinkered with an old fan motor and attached it to a soap box stapled to a broom handle. Using a pillow case as a dust collector on the contraption, Spangler invented a portable electric vacuum cleaner. He then improved his basic model the first to use both a cloth filter bag and cleaning attachments, and received a patent in 1908, and formed the Electric Suction Sweeper Company. One of the first buyers was a cousin, whose husband, William H. Hoover, later became the president of the Hoover Company, with Spangler as superintendent. Hoover's improvements resembled a bagpipe attached to a cake box, but they worked. Sluggish sales were given a kick by Hoover's 10 day, free home trial, and eventually there was a Hoover® vacuum cleaner in nearly every home.
Other Trivia - John Thurman
John Thurman started a horse drawn (door to door service) vacuum system in St. Louis, similar to Booth's. His vacuuming services were priced at $4 per visit in 1903. He invented his gasoline powered vacuum cleaner, in 1899 and some historians consider it the first motorized vacuum cleaner. Thurman's machine was patented on October 3, 1899 (patent #634,042).
Carpet Sweeper
The dust kicked up in Melville and Anna Bissell's crockery shop and inspired Melville Bissell's invention of the carpet sweeper. Originally developed to preserve Melville's health by sweeping away the dust, the Bissells soon recognized the sweeper's market potential. Women neighbors of the Bissells, working out of their homes in Grand Rapids, Michigan, put together the inner workings and cases of the sweeper. They secured tufts of hog bristles with string, dipped the tufts into hot pitch, inserted the tufts into brush rollers, and trimmed them with scissors. Mrs. Bissell then gathered the parts in a clothes basket and took them back to a room above the store for assembly. While production was underway, Mr. Bissell was on the road selling his new invention. To demonstrate, he threw a handful of dirt onto a carpet while his prospective customer watched the dirt disappear into the clanging contraption… a sale was made. The Bissell Carpet Sweeper ® remains virtually unchanged today.
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
The first power supply was created in the 1920s, as devices used for powering residential and commercial radios. Many changes have occurred over the decades from using vacuum tube linear regulators, to the use of semiconductors, and eventually fault tolerant devices.
