Mr. Whitcomb Judson was really a clever man. He invented a special train that was pushed along by air
and in 1893 he invented something like a zip(拉链) that could be used to open and close clothes. It could be used
on men's trousers and on ladies' dresses. He did not call his invention a “zip” but everybody says that he was the
“Father of the Zip”. Mr. Judson tried to sell his invention but no one wanted it because it did not work very well. A
Canadian changed Mr. Judson's invention and made it better. He made a zip that worked very well in
1913. This is the same zip we use today.
