lpf-ritication forming part of Letters Patent `Nov 7,672, dated September 24, '1850 Reissue No. 8,11, dated September 13, 1859.

""0 mi whom it may concern:

.lie it known that I, P. A. PALMER, ofthe city Troy, county ot' Rensselaer and Si ateofNew York, and formerly of Le Roy, in the county of Genesee and State atoresaid,ha\e invented new and useful Improvements in Cook-Stoves and Heating Elevated Ovens; and I do hereby declare that the following is a. full and exg act description of the natnre,construction, and i operation of the salme, reference bei ng had to the accompanying drawings and to the letters 4 of reference marked thereon, and making al, part of this specification, in Whichy Figure 1 is a vertical section through the stove from the front to the back, taken on the 1 line .r a: of Fig. 2, which figure is a top viewof l the stove'rrith the oven removed and a part ofthe top .plate broken away Fig, 3 is el .j'ront view of the oven witha the front plate E removed, thereby showing the arrangement of l. the fines around the oven. Fig. 4 isa perl spcctive view of the oven grate.

Like figures represent likeparts. l The nature of my invention consists in the l arrangement of any kind ot revertible dues in 1, elevated ovens for cook-stoves, no matter how t or in what manner such lines are or may be l formed, constructed, ormade, or in what kind i of elevated ovens thesaid fines are or may be constructed or arranged, which 'are hereini after described.

It further consists in so constructing and ary ranging an oven-grate so as to adm-it of its being drawn nearly out from the oven, and then and there supported inV nearly a horizontal direction, notwithstanding the weight l thereof, and an additional weight of any suhi stance placed thereon for baking or cooking l purposes. l Italso further consists in the-arrangement of a damper, hereinafter described, so that by such arrangement andthe combination of such damper with the body or main part of the stove and the elevated oven the heat or heated air is flly and completely controlled at the will of the operator, in its passage from the main partof the stove into the elevated oven, and'admitted to or excluded from the aforesaid tlues, or allowed to pass ofi' or away through the exit-pipeA l To enable others skilled in the art, to make,

construct, and use my improvements, 1 will operation of the same.

My stove has an eleva/ted oven which is immediately connected to and with the main or body part of said stove without any intervening neck or pipe. This oven is constructed with an outside and an inside plate, between which I arrange revertible lines, hereinafter more t'ull y described, for the purpose of retaining and more evenly, successfully, and completely distributing the heat throughout the entire oven. I divide the space A surrounding the said oven into any desired or required number of [luessuch as a a, b b, &c.-in the front and in the back ofthe said oven. I then admit draft iu and to the tiues a a at the lower end land bottom thereof, consequently, at the bottom of the oven. Tbedrnft then passes up the said lines to an opening in the partitionwall between the said ues an. and b b at or near the top thereof; thence into and down l the fines b b to an opening in the partitionwall between the said fines b b and the double flue c, at or near the bottom thereof; thence into and up the double flue c to the exit-pipe d, from whence it passes oti or away, as shown and represented by the arrows. When the oven is not in use, the draft maybe admitted immediatelyr to the exit-pipe d through the double line c, which is done by openingV the damper e. The great advantages in and by this arraugementot lines are, rst, .the retaining ot' the heat around and about the oven for a greater length of time than could otherwise be done were it not for these fines; second, constituting ita more even and perfect baker; and third, the leading and bringing the heat directly to the respective ends of the said oven, and thereby throwing and passing it immediately under the boiler-holes gg upon the top of said oven, which have heretofore been inoperative ainl of no use on account of the want of heat being conducted away therefrom by means of a direct line of draft from the stove to the exit-pipe, but now by the use ot' said fines rendered operative and of great use on account of the heat being conducted to their immediate locality.

When more than two boiler-holes are formed in the lower part of the stove, I arrange the grate B back of the front boiler-holes. Then, thejre being huilt upon this grate, the heat here proceed to describe the construction and is applied moi e directly to the bueh hoileis y and oven, without heating the entire stove, thereby saving a great proportion of the fuel h v shortening the passage l'or the heat. This grate may be made in any required or desired way, shape, or manner to answer the purpose.

The oven-grate t', l construct and employ with hook ff projecting below so as to guide and hold the said grate upon the bearing rods or projections q g, Fig. l, upon the inner plate i of the said oven. These guides or bearings for the said grate (shown at Fig. 4, and partly drawn out from the, oven in Fig) may be of round or square rods ot' iron` and fastened therein by means ot' the ends of the said oven into which the ends thereof are inserted, or they may he east ot' iron with a channel 0r groovetlwrein7 and extending the entire length 1 thereof, and fastened in and to the said oven,

as hereinbet'ore deserihed. This grate, when thus arranged, being` drawn in part or nearly ont fiom the said oven, will sustain aud snpport itselt with its own weight and the weight great end designed, and the fulfillment andf carrying out of the principle herein and hereby described by the use ot" said lines. These partition-Wallsv may be made ot' castiron, smooth or corrugated, as the case may be, or it may be made ot' boiler-iron or sheetirou and smooth or corugated, or they may be made ofhollow pipe, either castiron, boiler or sheet iron, and placed in close proximityto each other,

or they may be made by using a double thick of material thereon i'onbnhing or cookingpur- 1 poses, at` any distance or point whenever de- Y sired, until the said grate he entirely removed from the oven. constructed along the edge ol' the said grate on either side thereof.

and c, Ste., and immediately between the lower part ofthe oven aibresaid, and the top or up per part ot' the stove, or it may be so con- (rooves or channels may be ness of either t'orm, shape, or manner in which they are or may be made or constructed.

Having thus described my improvements, what I claim, and desire to secure hy Letters Patint, S-

1. The arrangement and combination ot' re vertible fines in elevated ovens ot' coolestoves i with partitionn.lls, iu the manner as and for The damper e, Fig. 2, I construct so as to slide or open directly from under the tlnes b b structed and arranged'as to turn upon a bear- I intr at each end thereof, and operated in any convenient way or manner. This damper is the purpose herein described and set torLh.

2. The arrangement and comhin-.ttion ot' the oven-plate cin and with the inner platel and ends ofthe oven, as and for the purpose herein herein described and set forth.

3. The arrangement of the damper c immey diately between the main part. ot' the stove made in length to correspond to the distance between the partitiolrwalls of the titles a aA and ot` any desired width. This damper is for the purpose ot' regulating', guiding, and controlling' the heat in its passage t'rom the main or body part ot' the stove into the aforesaid tiues, and thereby regulate the heat or temperature ot'the elevated oven, as at'olesaid. It therel'ore eoiupels the heat to enter they tlues o r when it is closed, or when opened allows it to pass immediately and directly tothe exity pipe without being eoualized or distributed over and about other parts ol' the said oven. 3 lt` will, therefore, he seen that without this and the bottom or lower part of the elevated oven, thereby combining it with said oven, the stove, and the double tlne c for the purpose of'eontrolling audlregulating the heat in its passage into the tl ues ofthe said elevated oven, as herein described, disclaiming any damper found in any stove not having an elevated oven, as herein set forth.

ln testimony whereof l have hereunto swr my hand on this 19th day ot' July, 135.
