with means for raising and lowering the fur nace at one or both ends. The said means may be a pair of pistons simultaneously hydraulically actuated, or may be, as shown at 9, screws carrying wheels 9, adapted to be turned by worms 9b on transverse shaft 9C in nuts 9d, fixed to a bed 11, 10 showin a joint or pivotal connection of a bracket ho ding the screw-head to a corner of the furnacebody. In Fig. 4 the pivots 7 and their supports are only partly shown, so as to allow the tilting means to appear more clearly. The rabbles 14 are disposed in two or more lines, each rabble separately, and all collectively being driven in positive. relation one to the other. They transfer the ore from one to another continuously, materially, and longitudinally from the end of the furnace, havlng means for the feeding in of ore 15 to the end having means of ore-discharge, (shown by chutes 16,) this end also having the {irep ace and its accessories.
The furnace has, as Figs. 2, 3, and 1 show, a fume-outlet 17 for ases from over the hearth and a second me-outlet 17 for 1gases from compartment 21. Outlet 17 as a damper 18, which when raised by an f suitable means (not shown) allows the a mission of hot gases into the fiue 19 of the chimne r-stack or the like. Fume-outlet 17 has a amper 18, which when raised allows the highly-heated gases to pass direct from over the hearthintoue 19; but when damper 18 is closed such passage is prevented, and there is then a passage and an opening from 17 down into compartment 22. A lower part of outlet 17 is marked 17b in Fig. 1. (Shown by breaking away part of outlet 17.) The up er part of outlet 17 is marked 17C. The en of outlet 17 is broken off in Fig. 3 to show the end of outlet 17. The gases entering compartment 22 pass along the same and turn into com artment 21 at the end of artition 23, as in icated by dotted arrow in ig. 2, and after traversing 23 enter flue-outlet 17 and thence reach flue 19, as indicated by arrows in firm lines. There is a raised wall or bridge 17d at the hearth-feed end to prevent strong draft carrying away ore, which would otherwise thus be lost. When it is not desired to use the under chamber for the continuous circulation therethrough of heati, prevented.
When it is desired to cool the hearth, the
`side inlets thereto may be fully o ened, as
well as the inlets to the under-cham er along the sides thereof, and circulation of hot gases into the under chamber is then not permitted. Each damper is ada ted to be raised or lowered to the extent esired independently.
The two entrances 27 Q7 to Hue 19 are each larger than the ends of the fume-outlets 17 and 17, projecting into said entrances but the space around the said ends is com letely closed by ) lates 28 and 28 Each of) these plates is a apted to slide in suitable guides 30, so as to rise and fall as the furnace is tilted.
30 is a tie-bar.
29 shows an aperture in plate 28, through which part 17 projects, and plate 28 is similar.
The parts shown in Figs. 5 and 6 are on a lar er scale than the other figures.
Iliere may be any suitable framing, connections, couplin s, bearings, and the like su orted upon t e furnace-to to position tle lbngitudinal shafting and `t e rabble-stems, and in such manner that any desired rabbles may be taken out through holes in the furnace-to (shown at 25) when said holes are relieve from means used to close them during the working of the furnace. The said framing and other parts are marked 24.`
The shaft of pulley 6 is made to operate intermediate gearing 26, driving spur-wheels, as 26, which turn driving-shafts 5 in opposite directions simultaneously.
In practice tilting makes the feed end the higher. I may construct the furnace with a support at the feed end operative when the furnace is level. As shown, the flue- apertures 27 and 27 have their bases so operative by supporting outlet ends 17 and 17. Parts, as 9 to 9, act as tilting means and as supports and holding means also.
Modifications may, however, be made in various details within the spirit of this invention. For example, a single slide-plate instead of two may be used.
What I do claim as my invention, and desire to secure by Letters Patent of the United States, is-
1. An ore-roastin furnace, having a air oflongitudinal cham ers, one above the ot er,
and a connection between them, the upper chamber being for ore, a plurality of lines of rabbles in the u per chamber having the intersecting heart areas, the said lower chamber having the longitudinally-extending partition therein and dampers controlling the fume-outlets of the said chambers, substantially as described.
2. An ore-roasting furnace having a pair of lon itudinal chambers, one above the other, an a connection between them, the upper chamber being for ore, rabbles in the upper chamber, the said lower chamber having longitudinally-extending artitions therein, and dampers controlling t e flue-outlets of the said chambers, substantially as described.
3. An ore-roasting furnace comprising an ore-roasting chamber, a lower chamber, divided to make a circuitous channel for the hot gases, a flue, both of said chambers being adapted to discharge into the said flue at the IOO seme end of the furnace, en eipe means of gases either into the lower chembe or into for conf-.Toning the discharge of the 'ases the Hue and dem er means eontroing the either into the flue direct or into the ower essege from the ower chamber to the said chamber and thence int-0 the said ue, subue, suhstantiay as described.
