The Schedule referred to in these Letters Patent and making partvof the sante.

To all cham it may concern.-

Beit known thatl I, A.- L. BGART, ot' New York.

city, in the county ot' New York, and in the State ot New York, have invented certain new and ,useful Improvements in Gas-Ranges; and do hereby' declare that the tollowingis a full, clear, and exact description thereof, reference heilig had to the .accompanying drawing, making apart of this specification, in which-l Figure 1 is a front elevationof my im provedA range.

Figures 2 and -3 are end elevations of the same.

Figure 4 is a plan vie\v`ot'- the upper side.

Figures 5 and 6 are vertical. longitudinal sections on the lilies x 'az and y y, respectively, of figs. 2, 3 and 4.

Figure 7 is a vertical cross-,section on the line 2 z .of figs l and 4.

Figure 8 is a broken vertical cross-section on the line zl of tig. -5.

Figure 9 is a plan view'of the lower side of the'v 'and arrangement ot' the. various parts of ther-ange,

whereby they are so adapted toeach other, as that, when combined, a most convenient, effective, and economical device is produced, capable of performing, in

Aa superior manner, all ofthe. o tccs usually required.

1t also consists in 'the' general form and construction of the burner for heating the ovens, in combination with the mixing-chamber connected therewith, as is hereinafter l'ully set forth.

A represents the top, B, the bottom, and C and C',

-the endsot' the range, constructed ot' sheet-iron, in

the general form shown vby the lrawings.

The interior ot' the space thus formed is divided longitudinally, by means ol' a vertical partition, D,

placed about. one-third the distance between the ends, e

and in the largest space is suspended, in v"the usual manner, V`an oven, E, the liont ot' which is open, and extends to the trent ot' the range, while. between its ends, rear, and top, and-thc corresponding contiguous portions of said range, is left a suitable tine for the upward passage of the heatedfair from ythe burner l",l

situated immediately. beneath said oven;

As shown in rigs. 6 and 9, the burner F consists of an oblong hollow metal bok, corresponding inlsize with the bottom ot' the'oven, and provided, at one end, with an outward-projecting neck, j', which ext-ends through the end ofthe range, and has connected thereto .the

upper end ot' a shortpipe, G, forming the mixing chamber.

v The lower surface ol' the burner is provided with pertbrations for the cscapeot 'the mixed gas and air, while, at its centre, is a-circnlar opening, f', which extends through said burner, but does not communicate with its interior, the obiect ot which ,will hereinafterbe explained. I

T-helower end of the mixing-chamber G is open, and has attached thereto a ring, g, having secured'in its cent-re, radially, a nipple, 7i, by means of two or more tins or webs connected to both ring and nipple.l

The supply-pipe H being suitably connected to the lower end of said nipple, the gas passing upward from the latter produces a partial vacuum inthe lower end of the mixing-chamber, into which the air rushes, and,

uniting with the vascending current 'of gas, forms a mixture, that escapingdownwad through the openings in the burner, is consumed with a blue, inodorous e ame.

.The heat thrown downward from the burnerA I" is suicient to roast any article placed beneath in the ove'n I, and from the ease with-which the liowV ot' gas, and, consequently, the degree of heat, can be regnlated, this usually most ditcult operation becomes a pleasant task.

Theheated air from the roasting-oven passes up. ward through the 4tlueszd, around the baking-oven, and finally escapes through the pipe K, extending upward and rearward from the top-'plate,'by means of .which the necessary quantity ot' heat is communicated to said oven, to enable the baking therein of any desired articles.

The space L, to the-left o f the vertical partition, forxnsa warming-closet, a sutticient amount of heat being radiated lthrough said partition to warm such articles of t'ood as may he placed therein.-

In order that a greater amount ot' heat may be admitted within the closet, when desired, than would he radiated through the partition, a number of openings,

l, are made Athrough the latter, which openings are closed, and the admission of the heated air regulated hy' means ofa slide, l.'

It being very ditiicnlt to constructthe doors to the .ovens and warming-closet with such accuracy as to entirely exclude the outer air, it istound that a sulii` cient -quantity is admitted to the roasting-oven, around its door I', to supply the requirements of the burner F,and also to furnish the necessary upward current for heating the upper oven; but in case that such means vshould prove insntiicient, suitable openings might be provided in the door, bottom, or sides ot' said ovcn'I, to admit the required supply. A

lhe upper side of theburner F is placed in contact with the bottom of the' oven E, and the heat threby communicated to the bottom of said oven is found to he sufficient, but, it' desired, a Hue, corresponding with that upon the sides oi' said oven, may be provided beneath the saine, and the heated air admitted thereto by means of the circular opening f, at the centre of said burner.

4 In order that the ordinary operations of cooking may he perdu-ined, a number of upward burners are provided upon the top of the range, those near the front" corners M (the general shape of which is shownin figs. 4 and 5) having been secured to me by'Letters"I Patent, No. 92,931.

The burners M are provided with mixing-chambers m, similar to that connected to the burner F,"and have placed over each a cylindrical casting or crown, N, the.,

upper` end of which corresponds in interior diameterl with the'size of the utensils to belemplo'yed thereon.

A ledge, n, extending around the interior of leach crown, a short distancebelow its upper end, contracts the Vsize "f-the opening, and cansesjthe heated airand liame to'passupward atthecentre only. a

` G, 1?,"an`dIt, represent threeyburne'rs, of thesliape shown `in igL`l0,whiclifare placed in front and nearV the rear, upon the'top of the rangeand receive a supspcctir-"llv, which pipes extend outward and downward, und areconnected with the main supplypipe S, extending horizontally around the ends and rear of said range. Suitable erow1`i-cas`ti1`1gs heingplaced 'over said burners, the range is complete.

il, nl

Second, the downward burner is the only one ever employedwhich does not produce a sufficient quantity ot' soot to render its use entirely iinpracticable, and,

therefore, this range is the first inwhich a practicable i roasting-oven has been possible.l

Third, the general construction and, arrangement of ftheseveralparts of the' device are such as to insure great convenience, without rendering the range at all "bulky, and as it can be entirely constructed from sheetlof my invention,

What I claim as new, and desire to secure by Let 0ters Patent, is

The within-describedrange, providedvwith the `ovens E and I, the warming-closet L, the burner F provided with the mixing-chamber G,`and'the upward burners,

M, O, P, and It, (or either separately,) all constructed and arranged to operate substantially as and forlthe purpose specified. 'l l "Also, the employment ofthe o'peningsand slide, l and l', respectively, 'withinand upon the partition D, snhstantiall y as and for the purpose described.

"Also`,in combination 'with the ovenslE anduI, and closet L, connected by means 'oi' the openings Z and slide Z', the downwardburner F, (either with or withont the central opening f,) provided with the mixingchaniber G, substantially as hereinl described, and for the purpose specified.

In testimony that I claim the foregoing, I have hereunto set my hand, this 20th day of September, 1869; a

A. L. BOGART.
