    Provisional Specification. Sloughgrove Q Wheatley's Improvmients in Furnaces and Ovens, the front screen and pushing back a portion of the incandescent fuel from the outer fire; the screen is then raised. When coal is thrown upon the outer fire, the smoke and gaseous products arising from its combustion pass through the screen and over the second fire, by which they are ignited and consumed. The object of the second screen is to prevent the gaseous 5 matters passing over the incandescent fuel of the second fire too quickly, and escaping into the chimney unconsumed. By the foregoing arrangement the visible and combustible gases are entirely consumed, the heated air and invisible vapour alone passing off by the chimney. In some cases the second bridge or screen will not be required, but we reserve the right to vary the 10 details of this Invention. LONDON: Printed by George Edward Eyre and William Spottiswoode,
