Abstract

12,159. Slingluff, H. G. June 29, 1905, [date applied for under Patents Act, 1901]. Glass furnaces; discharging.-A tank for drawing glass is provided with a telescopic hood or cover having openings through which glass may be drawn, and arranged so that, when the drawing operation is completed, the cover may be raised to allow products of combustion to pass over the glass in the drawing-tank. The drawing-tank 5, which is constructed preferably of metal lined with refractory material, is provided with a neck 6 connected to the melting-tank 1 through a valve, and the tank 5 and its neck may be heated by a furnace beneath them or by products of combustion conveyed to the flue 9. The tank has a verticallymovable or telescopic hood or cover 10, from opposite ends of which project short flue sections 11, 12, so that, when the cover is raised, these sections communicate with the flue sections 3, 13, respectively, and, the damper 4 being opened, products of combustion flow from the melting-tank into the cover, for the purpose of melting down chilled portions of the glass, and finally escape to the main flue 14. Instead of using the products of combustion from the melting-tank, an independent supply may be used. Circular openings or slots are formed in the hood for the drawing of cylinders or sheets, respectively, the openings being covered by a plate when the hood is raised.
