GEORGE FENWICK, OF GATESHEAD, COUNTY OF DURHAM, AND BRODIE OOOHRANE, OF DURHAM, COUNTY OF DUR-HAM, ENGLAND.
SPECIFICATION forming part of Letters Patent 1Y0/271,442, dated January. 30, 1583.
Application tiled January 24, 1882. (No model.) Patented in England June 28. 1881, No. 2,834.
l at a a portion ofthe iiame from the chamber To all whom it may concern Be it known that we, GEORGE FENwrcK and BRODIE O0CHRANE,'subjects of the Queen ot' Great Britain and Ireland, and residing re spectively at Gateshead and Durham, both in the county of Durham, England, have invented certain Improvements in Reverbera-tory Furnaces, for which we have obtained British Letters Patent No. 2,834, dated June 28, 1881, of which the following is a specification.
The object-'ot' our invention is to so construct a reverheratory or similar furnace as to utilize the heat under the most advantageous cir cumstances, in order to eli'ect economy in the consumption of the fuel; and this object we attain by constructing in the root of the furnace air-chambers and gas-fines, both communicating at one end with the ash-pit, and the gasues.communicating at the other end with the combustion-chambe`r, while the said airchambers communicate with an air-chamber below the hearth, as more fully described hereinafter. l y v 1n the accompanying drawings, Figure 1 represents a longitudinal section ot' our improved furnace on the line l 2, Fig. 4. Fig. 2 is a horizontal section ofthe same, taken along the line 3 4i, Fig. 1. Fig. ,3 is a longitudinal section taken along the line 5 6, Fig. 2. Fig. 4 is a transverse sectipn taken along' the line 7 8, Fig. 1; and Fig. 5 is a similar section taken along the line 9 l0, Fig. 3.
A are the tire-bars, situated overa closed ash-pit B. O is the working-hearth, and I) is the crown ot' the furnace, E being the chamber in which combustion takes place, andthe heat and flame are reverberated upon the materials contained therein.
ver the top of the chamber E are formed two hues, F, which in the present example are arranged one at each side of the furnace. These dues communicate 'at the rear end with the combustion or reverberatory chamber E by a small opening or openings, c, capable of being regulated by a valve or valves,f, and terminate at the front end in the closed ashpit B. By suitably adjusting, by the aid of the valve or valves f, the degree of opening E is diverted from escapingto the chimney at d, and is drawn into the fines F, along which it passes into the closed ash-pit B. It then passes over and between the iire'bars A, asindicated by the arrows, and intensities the heat in the chamber, this process being continued, so as to maintain acirculation from the chamber E, through the ues F, over and between the tire-bars A, and back to the chamber E. The gas-dues F are provided with a seriesof baffles, e e, which are composed of brick-work placed at an angle, and are so arranged that while they admit of a portion of the dame drawn in from the chamber E, as before mentioned, passing freely along the iiues F, the said baffles will at the same time f'orm an obstruction to the return ot' any gaseous products under the draft ofthe chimney.
As a means of supplying air to mix with the gases to support combustion, we employ an air chamber or chambers, G. arranged over the top of the furnace, and which may be con- Veniently constructed between the two chambers, F, as shown. Cold air is admitted at g into a chamber, H, beneath the hearth of the furnace, and from this chamber H the air, partially heated, is conducted by passages t' into the air chamberor chambers Gr. The air then becomes highly heated' by passing along the said chambers, and is mixed at h with the dame-gases from the iiues F, the mixture thence passing over and between the fire-bars, and further intensifying the heat. The airchambers Gr may be provided with perforated `brick partitions, if required.
By cutting oft' the communication with the chimney by means of a damper the products of combustion may be caused to circulate continuously from the chamber E, along the gasiiues F, through the chamber E again to the said flues, and so on in succession as long as required.
We are aware that it is not new to arrange gas and air fines in the roofs of furnaces. This we do not desire to claim, broadly; but
We claim as our invention- The combination of the combustion-chamher and ash-pit ol a furnace with the furnace l names to this specification in tl.e presence of top or crown I), having av passage, a, gastwo subscribingwitnesses. l
flncs FA F, leading to the ash-pit, and adjoin- GEORGE FENWICK.
ing air-chambers G. also communicating with BRODIE COCHRANE. 3 the aslrpit, the walls of the furnace having an Witfnesses:
air-inlet, g, and passages fi, and a chamber, H, CEAS. MILLS,
all substantially als described. JOHN JAMES,
In testimony whereof We have signed our Both of 47 Lincolns Inn Fields, London.
