Simple historical origins of barbed wire: Before the invention of barbed wire, looking around to make mankind in their fences materials, mainly trees, rocks, spiny brush and mud and other materials. When the colonists came to America when the earth began to find these in short supply, so they began to seek to create a more economical fencing. 400 years ago began producing cold-rolled steel wire drawing heat. In 1870, a variety of high quality silk smooth lengths have emerged. Stockmen with these smooth wire fencing ring, but was still found in poultry and out. In 1867, when two inventors tried to smooth the top with barbed wire. But there is no proof of the practice. Until 1874 Michael Kelly invented a very practical way to add in barbed wire top, and began a lot of use. Joseph Glidden found in ordinary small village which had a wooden rope with lots of sharp nails on its side, which is tied to the smooth wire. This discovery made him very excited. But also achievements in the shape of his invention of barbed wire now. Glidden ready to stab in a temporary abrasive coffee beans inside, then put barbed wire along a smooth interval and another screwed up a barbed wire around the fixed position. Prosperity and barbed wire: the future success of the invention Glidden continues today over 570 patented invention of barbed wire. It is "changing the world one face of invention." Glidden is known as the father of barbed justice. Many companies started production equipment for mass production.
