Thomas Blanchard

Japanese: ブランチャード（英語表記）Thomas Blanchard

1788‐1864
American inventor. He showed an early talent for mechanical things, and at the age of 18, he invented a machine that could make 500 rivets per minute. He later worked at the Springfield Arsenal in Massachusetts, where he made many inventions related to firearms manufacturing, such as a lathe that could cut the flat and oval parts of a gun breech and the barrel, paving the way for the interchangeable production method. One of his most important inventions was his gunstock-cutting machine of 1818, which became the prototype for the copying lathe. Although it was ugly in appearance, it used the principles of today's key duplication to efficiently make irregularly shaped objects, and was adopted by arsenals around the world.

アメリカの発明家。早くから機械的なものに才能を現し，18歳のときに1分間に500個のびょう(鋲)を作る機械を発明した。その後マサチューセッツ州のスプリングフィールド兵器廠で働き，銃尾の平たん部と長円形部および銃身を削れる旋盤など，銃器製作に関連して多くの発明をなし，互換性生産方式への道を開いた。なかでも1818年の銃床切削機は，ならい旋盤の原型となる重要な発明で，外見上は不細工であったが，今日の鍵複製の原理を利用して不規則形状物体を効率的に製作できるもので，世界の兵器廠で採用された。
