There 1S2. pipe 5 for each of the Cincinnati, in the county of Hamilton and two or more fuel chambers as may be in the (so 5 State of Ohio, have invented certain new furnace, the said pipes are connected to a and useful Improvements in Smoke-Conpipe 6 on the outside of the furnace by suming Furnaces, of which the following isv couplings 7. The pipe 6 extends across the a specification. front of the furnace above the doors 2 and is This invention relates to smokeless comj connected to a vertical steam pipe 8, on. the 1o bustion furnaces, and pertain especially to outside of the furnace. The pipe 8 is supimprovements in smoke consuming furnaces. plied with steam through a valve coupling The object of the invention is to provide 9, hereinafter particularly described, by a novel and peculiar means for introducing pipe 10, from the boiler 11, of the furnace. jets of steam and air combined into the fire The coupling 9 contains a valve 12 se- 15 box and over the fuel simultaneously with cured to a valve stem 13, working in a the opening of the furnace door for stoking cavity li of the coupling 9, and through a whereby a more complete oxidation of the packing gland 15 of the coupling 9.
