Speccaton of Letters Patent No. 1,456, dated December 31, 1839.

To all/107mm t may concern.' i Y Be it known that- I, FBENEZER Banuows, of li/iiattapoisett, in the county of Plymouth and State of Massachusetts, have invented certain improvements in the Manner of Constructing Kitchen-Ranges for the Fui-- pose of Cooking; and I do hereby declare that the following is a full and exact description thereof. l i

ligure l, in the accompanying drawing is a front elevation of my range, as setl in a lire place. Fig. Q, is a transverse section from front to back, on the line A, B, Figs. l, and 3, which is the line of the center of the range. Fig. 3, is a longitudinal. section through the line E, F, of Fig. 4. Fig. 4, is a horizontal section on the line C', D, Figs. l, and 3; and Fig. 5, a view of a part of one end of it.

n this range, the furnace, or fire-chamber, occupies the center thereof, the front plate, or portion, of it being seen at d, in Fig. l. The lines 72., L, on said plate represent projections between flutes, which 'l sometimes form on it for the purpose of increasing its radiating surface, as it is to be employed in the roasting of meat in a tin kitchen placed before it; this front plate is also shown at (Z, in Fig. 2, c, being the back plate, and b, one of the grate bars. in the sectional view, Fig. 3, where the front plate is removed, the back plate o, is, of course, seen, and c, e, are sectional representations of the side plates, Z9, b, b, being also sections of the grate bars. No. '2, in Fig. 4, is a cover, standing immediately over the lire chamber, and closing a boiler hole. The four cast-iron plates which compose the four sides of the furnace, drop int-o suitable grooves, or are furnished with tenons,"or dovetails, or are held together in any other convenient way, there not being anythin new in this part of the apparatus.

0n each side of the tire-chamber I construct an oven, as shown at G, H, Fig. 3, and at G, M, Fig. 2; that at M, being represented as closed by a door of the kind denominated the quadrant hinge door for ovens, for which l obtained Letters Patent, dated the 31st of Aug. 1837. Each of the ovens, and likewise the front of the fire-cha1nber, are furnished with such doors, whichare marked M., inl

the respect-ive figures, in some of which, they are represented as open, andln others as closed. 'l

In Fig. 3, f, f, are cast-iron plates, intermediate betweenthe side plates e, e, of the lire-chamber, and the inner side plates Z, Z, ofthe ovens; and'between these plates, an air space of half an inch, more or less, is left to regulate the heat; 7c, 7c, is a project-ing rim on the end'furnace plates, e, e, servingto close the space between these plates and f, f; j, .7', are tenons on e, e, which may fall into suitable mortises kin j", f. N, is the ash pit. There is an oven, marked I, inthe respective ligures,-which is furnished with shelves, doors, and theV ordinary appendages of such ovens; and under and around the back and top of this oven the draught from the fire may be directed; Vits flues are marked S, S; but as neither they, nor the oven which they are to heat, differ in any material particular from such -as are already in use, and are well known, a particular description of them would .be superfluous; they are shown merely for the purpose of exhibiting them in conjunction with my improvements. ,The draft around said oven may be arrested by a suitable damper, in the ordinary way, when its use is not required; g, g, represents an opening in the backplate of the boiler Hue, or space, z', i, leading into Vthe flues of the oven I. The top plate of this iiue, or boiler space, is marked g, g. Short partitions z, y, extend from the back plate of the boiler flue in the space i, z', toward the boiler openings l, 3, to force the draft through said space, into contact with the boilers; their place is shown by the dotted lines y, y, Fig. 4.

My principal improvement consists in the manner in which I carry the draft from the fire-chamber through flues around a part of the ovens G, and H. From the top ofthe boiler plate g, g, rise two columns a, a, which columns constitute iiues, up which the draft may be made t-o pass directly from the re,

as indicated by the arrows 4, 4, Fig. 3; or down, and partially around, the under part of the ovens G, and H, as indicated by the arrows 5, V5, 6. The places of the bases of these columns are shown at a, a, Fig. 4. Near their lower ends, there are two shutf ters, or dampers, m, and a, Fig. 3, the handles of which are shown at p, p; these valves lie upon each other, each of them filling, or being equal to, one half the section of the column; they maybe made to close it entirely, or partially, at pleasure. Partitions,

o, o, extend from the top plates of the ovens,

to the lower sides of the dampers, and when sok A io

the latter are inthe position shownfin Fig. 8, the iiue, leading from the-lower part of Vthe ovens into the columns,'will be closed,

and the direct drafft upf the vcolumns will then j take place; but if .the dampers 777 and n, are

both made to cover the oppositeV side of 'the partition V0, the direct draftlwillbepre vented, and the heated air will forced around the oven in the followingtmanner.

'A partitionr, r, divides the Aend fiue's oi.

the ovens Gr, I-I, intoV two, and 'extendsfalsoL under the ovens to about the middle ofthe lower flue, asindicated by thecroolredarrows,`6, 6, Figp), Y .v 'j In Fig.- 5, whichisanrend viewV of the range, the edge of thisV partition is'sh'ow'n by the dotted llines, 1, r, and by the lines r,

where its edge is seenVV through an Vopening made-*for clearing out ashes from the flue, the stopper ofwhichisremoved. f The draft, under this arrangement, will `pass down the filles in front of the partitions@ 1', vunder they ovens, and around said partitions at their termination at G, 6; thence on the op-` posite side of r, r, and up through the col umnsa, a, thereby heating the-vouternends,

and lower part, or'bottom, of the ovens.

The columns ai, a, open intofa hollow,'cast- Viron mantle K, K which forms their-"entablature, and the back side of which-man-A tle opens into the ordinary chimney flue O, O, Figf. To allow` of the `escape of' steam from the boilers, into the chimney, I

make an opening along the whole length of the lower plate of the hollow mantle, to which I vadapt a horizontal, sliding shutter, or damper, lwhich whenpushed back` leaves a longitudinal opening, from column to column, and when drawn forward, closes it.V

A section of one end of this "sliding shutter p so as to leave'the opening, "as shown at t. Y When theoven I, is omitted, which may be donefwitlilout interfering with .the arrangement ,o the other parts, the y chimney is tofbe closed bycafrrying` the brick-work uprijrom theboiler plate to the mantle.

I sometimes connectthe two ovens G, and

II, 'by forming a tunnel, or {opening, in the brick-work',passingback'of the furnace, so

'that'fthe heated airin' one oven will freely communicate With. the' other; by this device, I givel greater depth V.to these ovens, and may, if desired, `double ftheir capacity.'

from one oven to the other, at the back `of the furnace. "When such a communication is made, theordinary, back,.castironplates of the ovens are omitted, the fovens being contlnued back inthebrick-work, which, if preferred, maybe lined with iron plates.

Having thus, fully described the manner in which I construct mykitchen range, and `made known the use ofl'therespective parts thereof, what 1I claim as my invention, and

desire'tosecureiby VLetters Patent,'is-`-' The special "arrangement of the iiues, by

which theovens at `the ends or" Vsaid range are heated. Thatisto say, I cla-im, in com-` bination,thearrangement of the valves m, y

and n, the partitions 0, and r, and the colappurtenances, "which are constructed, and

operate, substantially inthe manner set forth.` A
