“barbed wire”的意思、由来-百科全书

barbed wire

fence wire usually consisting of two longitudinal wires twisted together to form cable and having wire barbs wound around either or both of the cable wires at regular intervals. The varieties of barbed wire are numerous, with cables being single or double, round, half-round, or flat and having a range of gauges. The twisted double cable provides extra strength and permits contraction and expansion without breakage. Barbs are diagonally cut in order to provide sharper points; they may consist of one or two pieces (two or four points) and are generally spaced at intervals of 4 to 5 inches (10 to 13 cm).

The first patents on barbed wire were taken out in the United States in 1867, but it was not until 1874, when Joseph Glidden (Glidden, Joseph Farwell) of De Kalb, Ill., invented a practical machine for its manufacture, that the innovation became widespread. By 1890, fenced pastureland had virtually replaced the open range in the western United States.
