改变世界14大发明：马桶 胸罩也入围

　　Paper Clip (1867)

　　According to the Early Office Museum, the first patent for a bent wire paper clip was awarded in the United States to Samuel B. Fay, in 1867. Despite the early patent, Fay's design never really took off; instead the Gem paper clip, which was never patented, took off in Great Britain. It's still the design we use today, producing 18 billion in the US alone.

　　回形针（1867年）

　　根据早期办公室博物馆的资料，能弯曲的金属丝回形针的专利最早出现在1867年的美国，发明者是塞缪尔•B•非伊。但尽管他很早就申请了专利，他的设计却从没流传下来。真正流传下来的是从未注册过专利的宝石牌回形针，在英国打开了市场。我们今天使用的回形针仍然是这一样式，仅在美国一国每年的产量就达180亿枚。
