Who Invented the Smoke Detector?

Who Invented the Smoke Detector?...

The history of smoke detectors started with American inventor Francis Robbins Upton. He created the first fire alarm in 1890. The patent no. was 436,961. He was a colleague of Thomas Edison but there’s evidence Edison worked on the device. Other Smoke Detectors Upton’s invention was very basic and other models would appear. The next one appeared by accident. In 1930. Swiss physicist Walter Jaeger was trying to make a sensor for poisonous gas. He was hoping that the gas would go in the sensor and ionize air. But the gas didn’t alter any currents. Jaeger lit a cigarette and saw the meter current go down. Jaeger’s discovery that smoke would affect the sensors changed the history of smoke detectors and how they were made. The Emergence of Home Smoke Detectors But these devices hardly made an impact. Electronic equipment made manufacturing very expensive. It wasn’t until the mid 1960s that affordable smoke alarms could be made. The few smoke detectors that were available were so expensive only large companies bothered to install them. The first home detectors were made by  Duane Pearsall in 1965. Their model made use of batteries. The design made it easy for homeowners to replace them. In 1975 Peterson and Pearsall began manufacturing smoke detectors. Their company Statitrol Corp was the first in the history of smoke detectors to sell the products. These models were comprised of metal and resistant to fire. The battery was made by Gates Energy. It didn’t take long before the rechargeable batteries were replaced by double A batteries. The devices proved very successful. By 1977, the company was shipping 500 units daily. In 1980, Statitrol sold its invention rights to Emerson Electrics. Sears would end up selling the product....

Who Invented the Kitchen Table?...

Who invented the kitchen table? That question seems not to have a concrete answer. Certain Beliefs on the Earliest Traces in History Looking back in history, no one seems to know who invented the kitchen table. And yet, with a blurry past some believe that the Ancient Egyptians can be traced back then to be the first ones to have used kitchen tables. Because of that belief, it has been inferred that perhaps these Egyptians who lived centuries ago had also invented the kitchen table and used it to their convenience. Whether that belief holds true to the real origins of the kitchen table, no one can actually say. Different Uses of the Kitchen Table during the Middle Ages While kitchen tables nowadays are solely used for dining, there were earlier accounts that these tables were also used for other purposes such as keeping things organized in the kitchen by placing certain kitchen supplies on the tables. It was also mostly used for preparing food. But, during the middle ages, the purpose of these kitchen tables for dining started with servants. There was a kitchen table in the kitchen area where household help and other servants eat on. African Receives a Patent for the Table In October 6, 1896, African inventor Henry A. Jackson got a patent for the kitchen table. At a time when kitchen counters were not a typical household item then, this inventor thought of organizing the kitchen with the use of the kitchen table. It was then used for dining and preparation of meals. Different Models Soon Emerged One by One Like other inventions, the kitchen table had gone through certain modifications that involved different materials and designs. Through the years, the kitchen table also...

Who Invented Fencing?

One of the most favored sports of sport enthusiasts is fencing. There seems to be an abundance of movies, TV shows, and sport events that actually feature and use this sport. Although that is the case, it seems that not a lot of those who like playing or watching this type of sport ever knew who invented fencing. So who invented fencing? Let’s check what history says. Earliest Points in History About 1200 B.C., there is evidence that fencing has been used before. This is supported by carving in the country of Egypt where a couple of masks, weapon protection tips, and judges were known to have existed. Also, during the early times of the Early Greeks and Romans, there are also some evidences that came up. These people were known to have a love for spears and short swords during their time. Also, it was said that during this civilization, chosen warriors learn their skills in schools that were called as ludi. Beginnings of Modern Fencing History says that it was during the fifteenth century when the origins of the modern fencing sport that we know now started to come into being. During the years 1471 and 1474, there were two of the first fencing materials that were published and distributed in Spain to those who are interested to know how to play this sport. During those times, there were also swordplay guilds spreading throughout Europe. In the 1500s, the use of the Rapier became more extensive and widely used by the Italians. The position involved using both hands with different weapons. As such, the person would be seen holding a particular weapon on the right and a small shield (also known as the buckler) on the left....
Who Invented Silk?

Who Invented Silk?

The Silkworm Legend Silk has its origins in China. According to them, the first person to discover it was the Yellow Emperor’s consort, Hsi Leng Shih in 3,000 BC. One day she sat under a mulberry tree in the royal garden to enjoy her tea. A cocoon fell from above into the hot liquid. When it did the strong silk thread unwound itself. The empress began raising silkworm and also invented the loom. In honor of her discovery, they gave her the title “Silk Goddess.” Archeological Evidence of Silk A recent archeological discovery appears to contradict this legend. It is a cup made from ivory and inscribed with silkworm designs. Along with the cup, they also found silk-making equipment. The items are believed to be about 6,000 to 7,000 years old. This has led experts to believe that silk must have been invented some 10,000 years ago! Excavations in China reveal further evidence of silkworm farming. In 1927 they found part of a cocoon along the Yellow River. It was estimated to be from between 2,500 to 2,300 years BC. Another find was a group of threads, ribbons and other pieces of silk dating as far as back 3,000 BC. These were unearthed in Zhejiang province. Use of Silk Silk was highly prized by the Chinese. At first, only royalty could wear it, notably the Emperor, his chief consort and his heir. Favored colors were white and yellow. Commoners were banned from using it. However people used silk in other ways. They would use it as parts for bow strings, musical instruments and fishing equipment. Silk was even used as currency. Eventually the old laws went lax and everyone could wear silk just like their king. Silk was quite...

The earliest chalk writings/drawings have been found in caves. As time went by artists from various countries used chalk to make drawings and sketches. Their work was protected using shellac or any comparable substance. For the convenience of these artists, a major innovation was introduced – chalks shaped into sticks. Even though chalk artists can’t be credited as the ones who invented chalk, their need introduced an innovation that would last for centuries. Making Chalk In the same way we don’t know who invented chalk, we also don’t know who invented the method to make chalk into sticks. What we know is that the method starts by grinding natural chalk into a very fine powdery form. Water is then added along with clay and various color pigments depending on what color of chalk you want to make. The clay actually acts as a binder of some sort. The mixture will initially look something like putty that would be rolled and shaped into cylinders and then would be left to...
