2 A.D. 1856.--Nº 2931. Provisional Specification

Green's Impts. in Manufacturing Glass Lights for Street Vaults, Ships, &c.

    I prefer the frames being heated to a dull red heat previous to pouring in the molten glass, for the purpose of expanding the frame or mould, and afterwards, in cooling, contracts and fits close to the glass, without injury to either.
    The Invention consists, secondly, in the apparatus used for ladling or conveying the molten glass from one furnace to another, or from the furnace to the casting plate or moulds. An iron bar is suspended from the timbers or ceiling, forming a railway for receiving a flanged pulley, to the axle of which is suspended a chain or rod; to the end of this is attached a ladle, having at one end a conveniently-shaped bowl for ladling the molten glass from the furnace, and at the other end a cross handle for the operator, this arrangement enabling a single attendant to convey the molten glass from the furnace to plate or mould at a much less expenditure of time and labour than has been done heretofore.
