Specification forming part of Letters Patent No.:'1d3,572, dated May 31, 1870; reissue No; 7,268, dated- August 22, 1876; application tiled May 31, 1876;

To all whom 'it may concern.-

- 'Be it known that we, JOSEPH H. UONNELLYJ formerly of Wheeling, West Virginia, now of New Brighton, Beaver county, Pennsylvania, and JOHN MCLURE, of Wheeling,-Ohio county, West Virginia, have invented a new and useful' improvement in process of, and apparatus for, collecting the mixed gases passing ofi' from furnaces, and from coke-ovens, Wherein bituminous coal is used, separating and purifying the carbonic oxide, hydrogen, and carbonaceousgases therein contained from'other gases, or the condensed products thereof, and applying the san e-to-aid the combustion in aid furnaces, and also in puddling-furnaces,

ind also preparing the same for illuminat pg purposes;

and we-do hereby declare the .ollomng tobe a full, clear, and exact de scription of the said invention, such as will enable others skilled in the art to makeand use the same, reference being had to' the accompanying drawings in two sheets, (like letters indicating like parts,) making a part of this specification, in which Figure 1, Sheet 1, illustrates, by a view chiefly in vertical section, our improvements as applied to a furnace-stacker cupola. Fig. 2, Sheet 2, illustrates the mode of collecting the gases from coke-ovens. Fig. 3 illustrates, by a view in vertical section, apparatus suitable for further treating the gas to make it ready for use; and Figs. 4 and 5 illustrate the manner of using the gas in puddling and boiler furnaces for heating purposes. In applying our invention to a furnace we lnclose the top of the furnace or cupola, and insert therein a pipe, E, for conveying or conducting the gases and substances given 011 therefrom over to a condenser, N. In apply- 1113 't to coke-ovens a similar pipe, sette -l in the top of the coke-oven, through which, in like manner, the gases and sub stances are drawn off from the ovens by means of an exhaust-pump or fan arranged, as at H, In the line of communication from the furnace or coke-ovens to the condenser N. This pump or fan is not'shown in detail, as We dcen. it unnecessary so to do. The-said gases r the scrubber or arates the substances from the'gases, the sub-v and substances pass off or are forced into the water-condenser N, wherein the substances, such as tar, &o., are separated from the gases,

and thence the gases pass into and through washer K,

which further sepstances, such as tar, &c., returning back into the condenser, from which they pass ofi'through a bent pipe, P. The gases are thence'forced through pipes B and 0 tea boiler-fire, asillustrated in Fig. 5, or by a pipe, B, to a fur mace-fire, Fig. 1, or to both, to aid in the com-' bustion thereof; or the gas may be still fur; ther purified by being forced, by-pipes B T, through limeor other purifier V, 'as shown in" the drawing, before being conveyed to the 'cupola fire, as described; and -:it may then also be conducted to and'used in a puddlingfurnace by a pipe, U, as shown in Fig. 4,

Toprepa're an illuminating-- gas from the furnace or coke-oven gases, the purifier 'V is employed, asset forth, so as to'separate the carbonic oxide and hydrogen from the other gases therein contained, as well as from other impurities, after which the gases so separated are forced and conveyed along through the pipes U T, Fig. 3, into the gas-holder Z, Where they are suflicientl y enriched for illuminating purposes, by the addition thereto of cannelcoal gas or oil-gas through the pipe X, andfrom which holder they are taken, to be con' 'suined, by suitable pipe Y.

As we do not confine ourselves to any particularly-constructed furnace or coke-ovens, or

apparatus for manufacturing gas, and. each and all of them, separately considered, being so, well known to those skilled in the matters to which they relate, we deeni it unnecessary to describe them in detail'fnrther than above done and shown in the drawing, but having inclosed the top ot'the furnace or cupola, as before stated, to provide for supplying the furnace or cupola with coal, metal, lime, &c.,

we construct two or more hoppers, (J, to,

around, or about and near its top, said hoppers having their bottoms considerably in;

clined toward the furnace, and opening them into by means of sliding doors, a, raised ahd carried out by their operation,

doors, when they will simultanc ously discharge themselves.

The'construction and operationv of said hop-z pers we claim as a part of our invention,

substances when, for any reason, it is not .de-

sired toappropriate theni' for the purposes a door, 1), made herein described, we have either in the top of cover of the top of the furnaceor in the pipe E, nearwhere it"enters the furnace.

The pipes and connections described are to -be furnished with a cocks or valves for directing the flow of gas suitable arrangement of as may be desired.

The dimensionsand capacities of the pipe E, ,exhaust-H, condenser N, scrubber K,purifier V, holder Z, and theirconnecting and discharging pipes, will be determined by the amount of gases and substances to be thus utilizedywhichcan be readily done by those conversant with the matter to which this relates. l

We do not claim as new of themselves these a parts or pieces of machinery thus designated and above described, but only theprocesses and the combinations thereof, as hereinafter set forth; and we claim that the mode of using said gases and substances will effect .a saving of what. would otherwise be lost, thereby economizing fuel, improving the quality saving the tar, and'aiding in providing an illumiuating gas.

\Ve claim herein as our inventionconveying v v ally as herein described, separating said subof iron,

1. The process of utilizing the gases and substances which pass off from furimces, eupolas, stacks, and coke-ovens, by drawing-or them-off by the means substantistances from saidgases, subs'tantiallyus' herein I described, and then applying said gases or the To provide for the escape of said gases and carbonic oxide and hydrogenobtained, by the means substantially-as herein described, to aid jand'assist thecombnstion in the fires of furnaces, substantially as set torth.

'2. The process of utilizing the gases and substances which pass off from furnaces, cu- .polas, stacks, and

coke-ovens, by drawing or conveying them off by the means substantially as herein, described,separating said substances from said gases, substantially as herein described, and then enriching the carbonic oxide and hydrogen obtained by the addition thereto of a coal or oil gas, to adapt it for illuminating purposes, substantially as set forth. v

3. The furnace or coke-oven pipe, leading from a close cover toor through suitable condensing and purifying apparatus, and in com- 'binatiou witha fan or exhaust for drawing off and utilizing the otherwise waste gases, substantially as set forth.

4. The combination of the furnace or cokeoveii pipe,'a condenser, N, scrubber K, purifier V, holder Z, and pipe X, for supplying to the contents of the holder a gas rich in carb ".1,

substantially as and for the purpose set for th: JOSEPH H. OONNELLY.
