from The Century Dictionary and Cyclopedia

  • n. A kind of huge stuffing-box used in a method of sinking shafts invented by M. J. Chaudron, a Belgian engineer, for preventing water from entering at the bottom of the tubing.


Sorry, no etymologies found.


  • Under such circumstances, Mr. Chavatte considered this moss-box as more detrimental than useful, and not at all indispensable, and so substituted beton for it, as had previously been done by Mr. Bourg, director of the Bois-du-Luc coal mines.
