Barbed Wire

sharp thinking leads to sharp ideas

invented by Joseph Glidden in 1874

When inventing barbed wire, there was a group called the "Big Four."They were Joseph Glidden, Charles Washburn, Jacob Hiash and Isaac Ellwood. They all wanted to make a more durable fence. So Glidden experimented with a grindstone and twisted two wires. In between 1873 and 1899 there were more than 150 companies manufacturing barbed wire. Another inventor, William Edenborn, invented an easier way to make barbed wire, which made the price of it drop from 17 to 3 cents.

How it works...

Barbed Wire Is a wire that is twisted by a machine, and then another wire is twisted around it to keep it in place. Then these two wires are wrapped around what are usually wooden poles stuck in the ground. The wires stick out of the stands to make sharp and pointy edges along the wire. Barbed wire is usually used to keep cattle in, or to maintain and mark off property.

now and then...

The barbed wire has not changed very much through the years because it is such a simple idea, but it is being used for more agriculture, and businesses. It is also used to make fences harder to get through by people by putting the wire on the top.
