Numbers, Words and Colors Science and Technology for a Clean ... Relearning Learning--Applying the L...A Brief discription of vacuum cleaner History Many products designed to make life and work easier emerged from the American/British Industrial Revolution. Of course one of them was the Wonderful VACUUM CLEANER!! Today the vacuum cleaner is taken for granted but its only been in the last 100s years that the vacuum cleaner has been around. Why basic carpet sweepers/hand pump operated vacuum type machines started to appear around the 1860s it was not and till 1901 when a British man Mr Herbert Cecil Booth invented the first mechanical vacuum cleaner.

He came across the idea when he had seen a machine "blew" the dust around but thought that sucking up the dust and collecting it a cloth bag. He proved the idea by placing a hanky on a settee/sofa and sucking with his mouth,and then trying to suck up as much dust as he could onto the hanky. Upon seeing the dust and dirt collected on the underside of the hanky he realized the idea could work well:o) Once Mr Booth built his vacuum cleaner which was 1st powered buy a petrol engine (later replaced with a Electric Motor) it was so large it was pulled around by a horse drawn carriage. Gaining the royal seal of approval, Booth's vacuum cleaner was used to clean the carpets of Westminster Abbey prior to Edward VII's coronation in 1901. Now that was good advertising!!;o) Booth started the British Vacuum Cleaner Company BVC which later became known as the Goblin vacuum cleaner company. As so in the USA in 1907, James Murray Spangler, a janitor from Canton, Ohio, USA invented the first practical, portable Upright vacuum cleaner.

Once he had patented the idea but could not afford to produce the machine himself he sold the patent in 1908 to William Henry Hoover.vacuum cleaner turbine design Mr Hoover then sold the machine under the name "The Electric Suction Sweeper Company" their first vacuum was the 1908 Model "O"hoover portable commercial vacuum cleaner Not to long after he rebranded the company HOOVER which we all know of today.intelligent robot vacuum cleaner price Many vacuum Cleaner companies started around the same time like Electrolux, Royal, Kirby, Eureka, Nilfisk etc which are well known around the world today. The main types of vacuum cleaner are Upright,Cylinder aka cannister,Hand held,

The main type of dust collection are Dust bags,used buy Kirby,Sebo,Oreck etc Bagless using cyclonic separation, used by Dyson,some vax and Hoovers etc. Water filtration used by Rainbow. Up to the 2nd World war the Vacuum Cleaner was a luxury item.But after the war the vacuum cleaner became far more common among the Middle classes and filtered through to the working classes in the 50s. Over the years vacuum cleaners have improved quiet a bit but the general overall machine has not changed to much. Why general performance has improved like air wattage and Filtration allot but not all vacuum cleaners have lost there build quality only lasting a few years and parts becoming obsolete quickly. But there are vacuum cleaners out there with high quality still built in like Kirby But just think what it would be like if there was no vacuum cleaners. Most Houses in the western world was dirt filled places and flea infested. Most people have memories of vacuum cleaners when growning up or older people when starting out with there new lives when setting up a new home.

Please feel free to view some of my vacuum cleaners from different eras and see which ones you remember.... One of the great merits of the Gettysburg Dime Museum is its economy. You could spend years crisscrossing the country to see a fish with a human face, or a Thalidomide baby in a jar, or the tongue of a hobo found stuck to a frozen fireplug -- and maybe never succeed. Or you could just go here. The museum is the collection of curator Mark Kosh, inspired by the dime museums of the 19th century, which charged people a dime to peep at novelties similar to those that Mark exhibits now, such as a flesh-eating toad with fangs; a human head in a box, stuffed with tea; and a two-headed duck. The goal then, as now, was to give people what they would pay to see. It's nice to know that our 21st century tastes and those of the average 19th century American mesh so well. Mark appears normal: no facial tattoos or ritual scarring. In fact, he's an Air Force veteran and retired Pennsylvania state trooper.

He told us he spent decades gathering strange things for his museum, which opened in 2016. "I always collected with the goal to share it with other people," he said. "If I was sitting in my basement drinking beer, staring at all this stuff, then I'd be a little weird." Some of the exhibits are blackened relics with yellowed labels, such as a viney mass removed from a teenager who ate too many seeds, and "the best example of a mummified pygmy ever exhibited in the United States." Others are more modern, such as the Sony Walkman of serial killer John Wayne Gacy. Not everything is real (which was also true in 19th century dime museums). Mark showed us "The Suicide Bride" exhibit, a stained wedding dress with an accompanying tale of a woman, jilted at the altar, who ran from the church and threw herself in front of a car -- which turned out to have the groom as a passenger (His car had broken down). Mark said that a visitor who claimed to be psychic was very upset about the bride. "I said, 'Don't feel too bad for her.

I made that story up.'" The most asked-for item at the Dime Museum is Abraham Lincoln's last bowel movement, supposedly removed from a chamber pot at Ford's Theatre and sealed under glass along with a faded, handwritten note asserting its authenticity. The "human coprolite" has been loudly criticized by some in Gettysburg, but most of the museum's visitors are fascinated by this intimate extrusion of the Great Emancipator. Mark said that his wife once overheard an elderly visitor tell her husband, "C'mon, honey, get my picture under the turd!" Mark said that Gettysburg is a good place of a for 19th-century-inspired dime museum. It's a popular destination for ghost-hunters ("They're already in the mood for something weird," he said) and history-minded tourists welcome the museum as a change of pace ("You can only look at battlefield monuments and cannons for so long"). Mark's only gripe is with visitors who breeze through the museum in ten minutes, then tell him how great it was.

"How do they know?" he asked us. "They didn't take the time to read anything. That's more than half the entertainment!" Mark is always on the hunt for worthy items, and told us that he still wants to find a two-faced lamb he saw in Niagara Falls when he was 15. One visitor, inspired by the museum, asked if he could make a donation -- which turned out to be a portrait of Marie Antoinette that he'd painted in human blood. The portrait now hangs between "skull of a Hellhound" and a strip of tattooed flesh in a jar, just one more wonder in Mark's museum of his favorite disturbing things. "If I was 9 or 10 years old," said Mark with a laugh, "I would've lived in this place."
