Question 2: What was the first invention of zipper for? The invention of zipper can be traced back to the end of 19 and the beginning of the 20th century. Judson, a retired American football player, is a smart and fat man. Boots with shoelaces were popular at that time. This is really not easy for his big feet. Every morning, he always has to make great efforts to complete the feat of putting on shoes.
Therefore, he tried to design something that could be pulled without problems, and named it zipper. This is the first zipper in the world.
However, Judson's invention did not attract much attention at that time. The real application and mass production of zippers is a Japanese named Tadao Gutian. He founded the world-famous YKK zipper and applied it to all kinds of clothes and equipment.
Question 3: What was the earliest invention of zipper to replace? /kloc-in the middle of the 0/9th century, zippers were originally invented to replace buttons on boots. There are more than 20 original hooks, which are extremely troublesome to put on and take off. But it has not been commercialized or even forgotten for half a century.
Question 4: What was the earliest invention of zipper to replace? The earliest invention of zipper was to replace:
The earliest invention of zipper was to replace: tie the supply belt.
tie shoe laces
Question 5: When was the zipper invented? Who is the inventor? Why did he invent the zipper? The information I found is:
1893, an American engineer named Judson developed a "zipper" and obtained a patent, which is the initial prototype of the zipper. The appearance of this device has an impact on the button hooks used in high boots. However, this invention did not catch on quickly, mainly because the quality of this early locking device was not up to standard, and it was easy to loosen at the right time and place, which was embarrassing.
Question 6: Who invented the zipper? Zippers are also called zippers. It is one of the top ten inventions that facilitate people's lives in modern times.
The appearance of zipper was a century ago. At that time, in some places in Central Europe, people tried to replace buttons and bows with belts, hooks and rings, so they began to experiment with zippers. Zippers were first used in military uniforms. During World War I, the US Army first ordered a large number of zippers to make clothes for soldiers. However, the promotion of zipper in the folk was relatively late, and it was not until 1930 that it was accepted by women to replace the buttons of clothing.
The zipper has its current name at 1926. It is reported that the novelist Francot said at a business luncheon to promote a zipper sample, "Pull it and it will open! Pull it again and it will close! " The characteristics of zipper are explained very concisely. The word zipper comes from this.
The embryonic form of the invention of zipper originally came from the boots people wore. /kloc-In the middle of the 0/9th century, boots were very popular, especially suitable for walking on muddy roads or roads with horse manure. But there are more than 20 hooks on the boots, and it takes a long time to put them on and take them off. This shortcoming is a headache for inventors, and it also costs sponsors a lot of money and patience. In order to avoid the trouble of wearing boots, people even put up with wearing boots all day. Finally, in 185 1, Alice? Elias howe applied for a patent for a similar zipper design, but it was not commercialized and even forgotten for half a century.
1893, an American engineer named Judson developed a "zipper" and obtained a patent, which is the initial prototype of the zipper. The appearance of this device has an impact on the button hooks used in high boots. However, this invention did not catch on quickly, mainly because the quality of this early locking device was not good enough, and it was easy to loosen at an inappropriate time and place, which was embarrassing.
19 13 years, Sambak, Sweden improved this rough locking device and made it a reliable commodity. The method he adopted was to connect the metal lock teeth to a flexible shaft. The working principle of this zipper is that each tooth is a small hook, which can be matched with the small hole under a small tooth on the next belt and the opposite belt. This kind of zipper is so strong that it can only be opened by sliding the slider to open the teeth.
Until190, a turning point appeared, a mechanical engineer from Chicago, whitcomb? l？ Judison (Whitb? l？ Judson), came up with a sliderdevice to fit and separate two rows of buttons (this principle is similar to zipper, but the term zipper didn't appear until about 30 years later). Judison's invention was fortunately invented by Pennsylvania lawyer Louis? Financial support from Lewis Walker. Walker is very interested in Judith's new design.
During World War I, the American economy was very depressed. Steel costs 5 cents a pound, and workers' wages are 6 dollars a week. The company laid off employees, leaving only Sam Baker and another employee, Sam Baker, who is both a manager and an engineer. The company's economy has encountered unprecedented difficulties. In order to repay the thousands of dollars owed to Jobolin Company, which supplied steel wire, Sembeck had to repair a machine for making paper clips to make money. Fortunately, sponsors will always appear. James, the father of the playwright? James O 'Neill is touring The Count of Monte Cristo, and he is very interested in Sembeck's zipper.
Although his career turned for the better, Sembeck personally suffered an unprecedented blow, and his wife died during childbirth. In addition to sadness, Sembeck is also committed to improving zippers. 19 13 applied for a patent again, and the patent license was approved in 19 17 (patent number 12 1988 1). Walker called this patent a "hidden hook" and was optimistic about the future. Walker renamed the company "Hookless Fastener Company" and moved the factory to Midvale.
Sembeck further improved the hook-free button. The shape of teeth is changed to spoon shape, the top is convex and the end is concave. When the sliding device slides, the left and right "teeth" can be embedded and then slide back to separate, which is called "Hookless No.2". A machine for manufacturing teeth is designed. 19 13 He officially announced that this technology had been broken through. America >>
Question 7: What was the first invention of zipper for? It's for zippers, also called zippers. It is one of the top ten inventions that facilitate people's lives in modern times. The appearance of zipper was a century ago. At that time, in some places in Central Europe, people tried to replace buttons and bows with belts, hooks and rings, so they began to experiment with zippers.

However, the promotion of zipper in the folk was relatively late, and it was not until 1930 that it was accepted by women to replace the buttons of clothing.
Question 8: About the invention of shaver.
1828 sheffield made a single-sided protection blade, which is the predecessor of the safety blade.
1895, American salesman Gillette met an inventor and painter? Painter wants to make a lot of money and invent something that needs everything and can be used once.
One day, Gillette shaved and found that the razor blade was just right for this idea. He designed a safe razor handle, but he couldn't find a manufacturer who could make thin blades. 190 1 year, he met Carson, the mechanic, solved the technical problem, integrated the hoe-shaped tool rest with the double-edged replaceable blade, and applied for a patent.
As early as 1900, the electric shaver was patented in the United States, but the first electric shaver suitable for commercial manufacture was designed by retired American army colonel Hick and patented in 1928.

Our ancestors made beautiful "transparent mirrors" more than 2000 years ago. At the beginning of the 4th century, Venetians made mirrors with tin foil and mercury on the back of glass, which looked very clear. In the 5th century, Nuremberg made a convex lens, and when making glass, it was made by coating it with a layer of mercury.
Modern mirrors are made by the method invented by German chemist Libiger in 1835. Silver nitrate is mixed with reducing agent to precipitate silver and attach it to the glass.
Traction chain
Zipper was first invented by Chicago mechanic Judson in 189 1 year.
In order to relieve the trouble of tying shoelaces every day, Judson invented a zipper which can replace shoelaces. This zipper consists of a row of hooks and a row of buttonholes. Pull an iron slider from bottom to top, and the hook and buttonhole can be fastened one by one. On 1893, Judson sent the sample to the Columbia Expo for exhibition, and thus obtained a patent.
Nowadays, there are more and more kinds of zippers, and their applications are not limited to daily necessities, but also enter the fields of scientific research, medical care, military and so on, and are praised by some as one of the great civilizations of the 20th century 10.
fridge
The first artificially refrigerated compressed poplar was invented by Harrison in 185 1 year. Harrison is the owner of Quilen advertising company. When he cleaned the type with ether, he found that the ether coated on the metal had a strong cooling effect.
Ether is a liquid with low boiling point, which is easy to evaporate and absorb heat. Harrison developed a refrigerator using ether and pressure pump through research, and applied it to a brewery in Victoria, Australia, for refrigeration and cooling during brewing.
The first refrigerator with motor-driven compressor was invented by Swedish engineers Brighton and Mendes in 1923. Later, an American company bought their patent and produced the first batch of household refrigerators at 1925.
high-heeled shoes
/kloc-A merchant in Venice in the 5th century often went out to do business, but he was worried that his wife would go out to have an affair. On a rainy day, he walked in the street, and his heels were stained with a lot of mud, struggling. Businessmen were inspired by this. Because Venice is a water city and boats are the main means of transportation, he thought that his wife would not walk on the springboard in high heels, so she might be trapped at home. Unexpectedly, his wife put on these shoes. Accompanied by servants, she boarded and disembarked and played around. High-heeled shoes made her more graceful, fashionable ladies rushed to follow suit, and high-heeled shoes quickly became popular.

/kloc-in the 0/8th century, MacIntosh, who worked in a Scottish rubber factory, could not afford rain gear because of his poor life. He has to go to work in the rain every rainy day. One day, he accidentally spilled rubber juice on his clothes and couldn't wipe it off, so he had to go home in this dirty clothes. When it rained outside, McIntosh was surprised to find that his clothes were not wet at all, so he simply coated all his clothes with rubber juice.
