Be it -know'n that I, WILLIAM .LA-Miroir,l a clti'zen of the UnitedStates,` andv a resident; of

-yl'ola, -Allen county, Kansas, have invented certainfnew andjuseful Improvements in Zinc-Smelting Furnaces ofy which the following is a specification containing va full,

' clear, and exact description, reference being v v*had tothe accompanying daWgSf forming y IO n a parthereof.

'My invention relates to zinc-vsmelting fur` i haces', and particularly' to .a furnace for the .heating of retorts used in thedistillationof gradual and perfect combustion of the fuel zinc ores and oxids into metallic zinc.

'The'primary-object of my invention is the arrangement ofa zinc-furnace `whereby a used for heating is obtained,- thereby producingnot onlyeconomy in fuel, Vbut at the same time'L 4a more unifo'rmfandy desirable 'character of `combustion and consequent f steadiness of temperature in the retort-fur` nace chamber which results are highly essen-` tial forthe proper volatilization anddistillation of, the metallic zinc`gand likewise the. savingv of the retorts or mufiies from de= struction usually vresultin from spotted, ir-j` regulan'and uncontrollab e heats, as is thef case in many furnaces heretofore constructed. l By my improved vconstruction the fuel .f is

v taken in atfthelower end or bottomofthe f furnace-chambers,v where said fuelris ignited and the firefandv heat thus obtained naturally;

pass upwardlythrough the retort-chambers7 strikeagainst the furnace roof or arch, and arev deflected `thereby downwardly, y and vthe j iame and heat are'withdrawn from outlets This arran e` ment, together withthe'admission of.`air orl combustion atfthe proper points, produces av 'condition wherebytheair and gases-are veryy easily rmixed yand intermingled, which .natu-i rally results in an easilyiregulatedjperfect A 1 y 2 of the furnace, and the compartments 11 The `construction *herein shwn and de-"f scribed is `designed .tov operate-with natural' "or artificialfgas orl any other suitable oil or] n i do not extend allthev way to the arches 4,

at the bottom of the furnace;

compartments

10 and 11, the compartments '10 being termedthe .f end compartments, kas they are adjacent the ends of the end walls being termed the middle com artments, owing to their location between t e pairs of 'the end compartments 10. The partitions 9 vso that-sufficient space-is providedlfor the -from the end to the middle compartments.

side walls l'to'thecenterwall 3, and extendroo furnace between the sidewalls and center wall are the retorts 12, which are of the ordinary construction.

Formed in the base of the center wal-l 3 at each end of the furnace and extending inward as far as the partition-walls 9 are airinlet ducts 13, and leading therefrom outward through the base of the wall 3 and discharging into the chambers 1() are the horizontally-arranged dischargelopenings 14.

Leading upward through the bottom of the -furnace into the baseof the center wall 3 is a -series of passages 15, the upper. ends of which.

extend horizontally through the base of the center wall 3, as designated (by 16, and discharge into the chambers 10, there being preferably one of these inlets 15 and discharge-openings 16 foreach one; of the openings 14.

Arranged in a suitable chamber beneath the furnace are gas-mains, such as 17, and vleading therefrom into each one of the passages 15 is a dischargenozzle 18.

Leading inwardly from the end walls 2 of the furnace through the upper portionof the center wall 3 and adjacent the arches 4 are .air-inlet passages 19, which extend to the .partitions 9, and leading from said inletpassages through the center wall 3 into the upper lends of the chambers 11 are the dischargeopenings 20. A series of air or air and gas inlet passages 21 are transversely arranged in Athey end-.walls 2 and extend from the side walls 1 to the center wall 3, and each one of these -passages 21 is intersected by inlet-openings '22, whichA are formed in the end walls 2 *and which discharge into the outer ends of I.fthe chambers 10.

Formed in the center f'w'al'l 3l and extending from one partition9 to lof which discharges intothel horizontal fiue 5.

"the other v-and between the compartments 11 is a vertically-disposedflue 2 3, the upperend 'The lower end of this fiue. 23 issom'ewhat wider than the upper portion,.'andlongitu' 'dinally-disposed in said widened* lower end is "abaffleplate 24, which extends from one end ,'"f'said iiue to the other. Leading through g'the' base of the 'center wall 3 from the lower l"eil-'dief the flue 23 to the .chambers 11, are the Ahorizontally-disposed openings 25.

The construction as just described, and as shown in the accompanying drawings, provides for two single-retort furnace-chambers.

arranged back to. backor divided by the center wall 3 and having nocommunication with eachother.

Each chamber comprising the compartments and 11 contains the retorts, and the space between and around the retorts in the chambers 10 is utilized for conducting the burning gases upward, and the space between and 'around the retorts in the chambers 11 is utilized for conducting said burnfurnace is identical.

ing gases downward, while the arrangement of gas and oil inlet iiues at the ends of the The gas or fluid fuel utilized for heating the furnace discharges from the nozzles 18' upwardly through the passages and horizontally outward through the openings 16. Here said gas or fluid fuel becomes mixed with air entering the

passages

13 and 15 and discharging through the

openings

14 and 16, and thus the mixed gas and air enters the chambers 10 and is ignited. The explosive effect of the mixture and the ignition of the air and gases aslthey meet in the bottoms of the chambers 10 carries them upward through the space -between and around the retorts in said chambers until they finally reach the arches 4, where they are thrown backward, and at the same time they are thrown toward the center of the furnace by the natural draft, and after passing through the spaces above the partitions 9 said ignited gases pass downward through the space between the retorts in the chambers 11, and finally discharge through the openings and pass from thence upward through the flue 23 to and through the flue 5 and into the stack 6.

Additional air, or a mixture of air and gas, may be discharged into the upper ends of the compartments 10 through the passages 1Q and openings 20, the` outer ends of which passages 19 can be partially closed by temporary fillings or suitable. draft-regulating devices. In the same manner additional air or a combination of air and gas may be discharged into the ends of the chambers 10 through the passages 21 and openings 22, the outer ends of which may be partially closed by temporary fillings or draft-regulating devices.

Suitable draft-regulating devices may be, A

' gases upward through the flue 23.

The draft of the furnace, as shown and d escribed, is produced by a stack or chimney; but this is not essential, inasmuch as the draft may be produced by moans of an cxhaust-fan or by forcing the air and. gas into the furnace by pressure.

1 desire to call especial attention to the arrangement of the center wall between the two retort-chambers and the constructionv of said wall for the purpose of throwing off the products of combustion after the same have passed through retort-chambers, which arrangement economizes space in the con- IOO lIO
