...Later in America, Burleigh C. Burleigh and others improved on Faull's patent in 1866, producing a pneumatic rock drill driven by compressed air, which they successfully used in tunnel construction. Meanwhile, in France, the pneumatic rock drill invented by M. Sommeiller in 1861 was actually used. Thus, the practical use of rock drills began, but in 1870, the modern type of rock drill with a separate drilling rod and striking piston was invented by American CH Shaw, which significantly improved drilling efficiency. ... *Some of the terminology that mentions "Sommeiller, M." is listed below.

…その後,アメリカでは,バーリーC.Burleighらが66年にファウルの特許を改良して,圧縮空気で駆動される圧気動削岩機を製作して,トンネル工事に使用して成功した。他方,フランスでは,1861年にソメイエM.Sommeillerが発明した圧気動削岩機が実際に使用された。このようにして,削岩機の実用化が始まったが,70年になると,現在のように削岩ロッドと打撃ピストンとが分離した形式の削岩機が,アメリカのショーC.H.Shawによって発明されて,さく孔能率が著しく向上した。… ※「Sommeiller,M.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
