MUNTZ, George Frederick. — The manufacture of sheathing metal, "by so using other suitable metal or metals when copper and zinc are combined for the purpose of sheathing, as to allow the mixture to contain a less proportion of copper than about sixty of copper and forty of zinc, and at the same time obtain a sufficient degree of oxhydation and prevent separate action on the zinc." "An alloy of copper and zinc with another metal," accordng to this invention, "suitable for sheathing, which I have found to possess the same properties of oxydation as my former metal," Letters Patent, Nș 6,325, "and yet with an important reduction of the quantity of the copper employed, and by which the cost of producing sheathing metal is materially reduced," consists of fifty-six parts of copper, forty and three quarter parts of zinc, and three and one quarter parts of lead."
