    Craig's Improvements in the Mode of Consuming Smoke, ^c. densed. / is a well or receptacle for any deposit from the smoke. Fig. 2, Sheet 2, shews another modification of my plan for washing the smoke, in which a, a, represents the passage of the smoke from the furnace by the bell- mouth of the pipe g, through which the smoke has to pass. The smoke at h is met by a jet of water from the rose c, and in its descent with the shower of 5 water down the pipe g, which should be made as long as convenient, by which means the smoke is condensed, e represents a cistern for the supply of water; /, a valve, which is opened by the lever Z and handle m, to cause the jet to work when required; d, the pipe leading to the rose e; h, the flue or con¬ tinuation of the pipe g, leading to the chimney i; and k is the drain to carry lo olf the waste water and deposit. Having thus fully described the nature and particulars of my said Invention, and the manner of carrying the same into practical effect, I desire it to be distinctly understood that I do not confine myself to the exact details herein described, as such may be varied or modified without departing from the 15 principle thereof; but I claim as my Invention, and which, to the best of my z knowledge and belief, has not been hitherto used within this realm, the arrangement of one or more furnaces or fire-places projecting from or formed in upper or lower shelves, or in one continuous line within the fire box, in conjunction with a series of water spaces, blocks, or bridges, forming go obstructions and chambers or passages for smoke and flame, causing them to pass through, under, or over the coked or carbonised fire in advance of or below the coal or green fire or fires, with a revolving bar or grate, and a door or doors to the water spaces, by which, with the admission of oxygen or atmospheric air at the time the fire or furnace is fed with fresh fuel, the 25 smoke is consumed; as all such improvements are herein described, and illustrated in the accompanying three Sheets of Drawings. In witness whereof, I, the said William Grindley Craig, have hereunto set my hand and seal, this Twenty-fourth day of April, One thousand eight hundred and fifty-five. 30 WILLIAM GRINDLEY CRAIG, (l.s.) Signed, sealed, and delivered by the within-named William Grindley Craig, in the presence of E. J. Hughes, ^ PatentAgent, Manchester. 35 LONDON: Printed by George Edward Eyre and William Spottiswoode, Printers to the Queen’s most Excellent Majesty. 1855.
