    6369Barbed wire

    Barbed wire, also known as barb wire, is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strands. Its primary use is the construction of inexpensive fences, and it is also used as a security measure atop walls surrounding property. As a wire obstacle, it is a major feature of the fortifications in trench warfare.A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. Barbed wire fencing requires only fence posts, wire, and fixing devices such as staples. It is simple to construct and quick to erect, even by an unskilled person.The first patent in the United States for barbed wire[1] was issued in 1867 to Lucien B. Smith of Kent, Ohio, who is regarded as the inventor.[2][3] Joseph F. Glidden of DeKalb, Illinois, received a patent for the modern invention[4] in 1874 after he made his own modifications to previous versions.

    There are more than 700 steel knots in The “Bobbed Wire” Bible, Jack Glover’s “illustrated guide to identification and classification” of barbed wire. They have names like Scutt’s Wooden Block, Greenbriar, Glidden Union Pacific, and the J. Brotherton Parallel. Scrupulously updated and republished by Cow Puddle Press starting in the 1960s, the bible—like the rest of barbed wire’s history—is one-part Americana and one-part innovation. Glover’s book and similar materially-specific compendiums (the Barbed Wire: Identification Encyclopedia comes to mind) document the minutiae of fencing materials and techniques. But these texts are also treasure chests of historical and cultural insight; behind each illustration is an inventor, a time, place, and origin story.Because that’s the thing about barbed wire: It’s a physical object—you could hold it in your hand if it wasn’t so sharp—but it’s also an idea.

    For years, barbed wire has been the wire of choice for farmers and ranchers because it is extremely economical and is easily installed on any surface. It  is typically used for cattle and bison, but is adaptable for a number of fencing needs.Barbed wire consists of two wire strands twisted together with either two or four point barbs placed at predetermined distances. The standard barb spacing is five inches; however we recommend three inch barb spacing for areas where high animal traffic, predator risks, or security are concerns.We offer barbed wire in a variety of strengths, coatings and styles from high-quality manufacturers including Bekaert, Oklahoma Steel, Keystone, Sheffield and Deacero.

    Late in 1876, so the story goes, a young man named John Warne Gates built a wire-​­fence pen in the military plaza in the middle of San Antonio, Texas. He rounded up some of the toughest, wildest longhorns in all of the state, or that’s how he described them. Others say that the cattle were docile. And there are those who wonder whether this story is true at all. But never mind.John Warne Gates — a man who later won the nickname “Bet‐A‐Million Gates” — began to take bets as to whether these powerful, ornery longhorns could break through the fragile-​­seeming wire. They couldn’t. Even when Gates’s sidekick, a Mexican cowboy, charged at the cattle, howling curses and waving burning brands, the wire held. Bet‐A‐Million Gates wasn’t so worried about winning his wagers. He was selling a new kind of fence, and the orders soon came rolling in.An advertisement from 1875 touted this fence as “The Greatest Discovery of the Age,” patented by J. F. Glidden of DeKalb, Illinois. John Warne Gates described it more poetically: “Lighter than air, stronger than whiskey, cheaper than dust.”We simply call it barbed wire.Compared to the telephone, barbed wire wreaked huge changes on the American West and much more quickly.To call barbed wire the greatest discovery of the age might seem hyperbolic, even making allowances for the fact that Alexander Graham Bell was about to be awarded a patent for the telephone. But while we think of the telephone as transformative, barbed wire wreaked huge changes on the American West and much more quickly.Joseph Glidden’s design for barbed wire wasn’t the first, but it was the best. Glidden’s design is the same as the barbed wire you can see today. The wicked barb is twisted around a strand of smooth wire; then a second strand of smooth wire is twisted together with the first to stop the barbs from sliding around.

    Barbed wire is a fencing material consisting of a metal cable with regularly spaced sharp projections. The cable usually consists of two wires twisted around each other to add strength and to allow the cable to expand and contract with temperature changes without breaking. The sharp points, called barbs, usually consist of short pieces of wire twisted around one or both of the cable wires.Fences of various kinds have been used since the earliest days of agriculture 10,000 years ago. Fences have been built from wood, earth, stone, and living plants (hedges in Europe and cactus in Latin America). Metal was not used for fencing until steel wire became available in the 19th century.Short lengths of wire were first made at least 5,000 years ago by hammering pliable metals such as gold. By the year 1000, longer lengths of wire were made by pulling rods of soft metal, such as alloys of lead and tin, through a die of harder metal, such as iron. In modern times, until the middle of the 19th century, most wire was made from wrought iron. By 1870 improvements in steelmaking made it possible to produce large amounts of steel wire for the first time.Steel wire was first used for fencing during the settling of the American West in areas where wood was scarce. Early wire fences consisted of single strands which were easily broken in cold weather or by wandering cattle. In 1860, Frenchman Leonce Eugene Grassin-Baledans patented the use of twisted strands of sheet metal with projecting points as a "fence protector." A similar method was patented in the United States in 1867 by Alphonso Dabb. That same year Lucien Smith and William Hunt received patents for single-stranded wire with barbs. In 1868 Michael Kelly invented the first double-stranded barbed wire, but the first commercially successful barbed wire was patented by Joseph Farwell Glidden of DeKalb, Illinois, in 1874. Similar patents were filed that same year by Jacob Haish and Leonard Ellwood, both also of DeKalb. After twenty years of legal battles, the United States Supreme Court decided in Glidden's favor, and he is often thought of as the "inventor" of barbed wire.The use of barbed wire increased tremendously in the 1870s and 1880s, with some unfortunate side effects. In the severe winters of 1885-1886 and 1886-1887 thousands of cattle froze to death when they were unable to break through barbed wire "drift fences" intended to keep them from straying too far south. Conflicts between ranchers who wanted unfenced pastures and farmers who wanted fenced croplands escalated into fence-cutting, land-grabbing, and violent range wars. Eventually the conflict subsided when it became clear that barbed wire was becoming necessary as humans and cattle increased in number.

    Barbed wire is used for various security fencing and barriers. It can be laid directly on the ground, mounted on the top of fence or in rows as an independent barrier. To prevent corrosion, barbed wire has a zinc coating. The barbed wire consists of barb wire and line wire. The wire diameter of line wire is larger. The line wire can have one wire or two wires. The barb wires are braided with a system of constant torsion around line wire. One barb wire forms two spikes and two pieces of wire-four spikes. The sharpened spikes are protective elements of barbed wire.Using the two twisted line wires can improve the quality of fastening studs and prevent the displacement along the wire. On a single strand barbed wire, in order to avoid spikes rotate around horizontal wire, the horizontal wire is made by corrugations and its cross section is not circular.
