TO ALL WHOM IT MAY CONCERN:
Be it known that I, PHILO I, STEWART, of the city of Troy, county of Rensselaer, and State of Newyork,
did, on tho18th day of January, A. D. 1859, obtain-of and. from the United States of America, certain Letters Patent for and upon new and useful Improvements in Cooking-Stoves, which said Letters Patent were duly lei-rendered, and thereafter duly reissued as provided by the law, bearing date the 31st day of May, 1864, and which said reissued Letters Patent have been found to be defective, in that they do not cover and embrace, in
the claims and specifications thereof, all of thc original invention and improvements contained in the drawings f first and originally filed in the United States Patent Office, to wit, on the 17th day of August; 1855, which application, after being once rejected, was duly withdrawn, and a new application upon the same invention and improvements was duly filed, as by law made and provided, to wit, on the 20th day of October, 1858, each of' which were in due form of law, but neither of which contained, in the specifications and claims thereof, the entire invention and improvements contained in the drawings originally made and filed in said Patent Oifice, as aforesaid; and being'now desirous to reissue the Letters Patent herewith surrendered, in the manner and form "as stated in the accompanying petition, in two'separatc divisions, with a separate patent upon each division, I prepared specifications and drawings of my said original invention and improvements; now, therefore, I do hereby declare that the following specification is a full, clear, exact, and more full description of that part of my said invention and improvements mentioned and contained in the claims hereto annexed, as well as of the construction, arrangement, and operation of the same, r'eference'being had to the accompanying drawings, and to the letters of reference marked thereon, is a part thereof.
Like letters represent and refer .to like or corresponding parts. v
Figure 1 is a side elevation of a cooking-stove containing my invention and improvements herein and hereby set forth.
Figure 2 represents a front elevation, showing the front doors opening into the ovcnand containing the apertures therein contained, and each and all hereinafter more fully described and set forth.
Figure 3 is a longitudinal vertical section, showing thcilifferent parts hereinafter described and set forth. 1
Figures 4, 5, and 6 are sections taken on and at the lines A a, B b, and C c of fig. 1 of the accompanying drawings.
Figure 7 is a front elevation, showing the front of the fire-box or chamber of combustion, and the hot-air chamber or mating-flue between the front-plate of such firebox or combustion-chamber and the front doors, ope-- g in the manner substantially-as hereinafter described and set forth, and'communicating with the oven, subs stially as and for thepurposesherein described and set forth in detail and at large.
nigure 8 shows the plate in the rear or he ck of "the oven, and immediately between the oven and the ver tical Tue or fines in the immediate rear or backiond of the cooking-stove, with openings or apertures therein of sufficient number and size as may be required to accomplish the purposes hereinafter described and set forth.
There are four sheets of drawings accompanying this division and specification, and they are respectively marked 2, 3, and 4, sheets, & c. V
The nature of my invention contained in this specification consists in supplying the oven of a cookingstovc \r 5: continued and fresh current of warm or highly-heated air, which shall be so heated byit's coming into COIN/a. V1; with thcfront plate of the fire-box or charfibcrlof combustion as it passes into the chamber -or flue between the said plate and front doors, through the apertures in said front doors, and thence down said chamberor flue, and along and upon the said plate of said firebox or chamber of combustion, and thence into the oven, whereby the operation of baking is much and greatly aided and facilitated, and thereafter passing out from said oven into the rear vertical end'fluc or flues, as' the case maybe, through the openings or apertures in the said rear plate of the oven, in a most perfect and satisfactory manner, substantially as hereinafter described and set forth.
I dire-grate, and ash-chamber, in the manner and for the purposes substantiallyas herein described and set forth.
chamber, below said reservoir, from the combustion-chamber, through suitable flues or fiue, in the manner subend of the stove, and thus it remains suspended within that part of said oven, while thelower partof-suchoien ex tends forward'and below' said fire-chamber to or beyond the front plate thereof. The said fire-chamber .intoan ash-pan in the said ash-chamber, if deemed best, so to use such an ash-pang I prefer, however, to use .nnd that the same are combined with the said fire-chamber,aud the whole thus arranged are suspended by struct andarran-ge asuitable door, 6, for the supply of fuel to said combustion-chamber. In said door, I conrequired;
It also consists in combining with a cooking-stove suitable doors in the front of the oven, extending outward to-the front end of the stove, under, and just below, the fire-ehamber and the ash-chamber, (necessarily used with said combustioii-chamber,) and which shall be of sufficient capacity to receive an open, tin, kitchen, or other roaster, so that the heat radiated by all the plates, and the back, front, and bottom. plates of the firechamber or box, into the oven, may" thus and thereby be employed for roasting or baking in front of the oven, when combined with a-n-end door, so that the draught may be controlled without the aid, and independent of, the front doors, substantially as herein described and set forth. I
It also consists in the arrangement andemployment of a suitable door or doors in the front of a cookingstove, and which shall, inpart or in whole, open into that part or portion of the oven which extends forward and under the fire-box or chamber of combustion, and other parts necessarily employed and used therewith, as well as open immediately in front of the plate forming the front part or portion of the fire-box or chamber of combustion, in the manner and for'the purposes substantially as herein described and set'forth,
Italso consists in the employment and arrangement of bc'ittom, and back or rear-end casings, or additional end and bottom casings, and arranged at a short distance from the real bottom-plate of the stove, while said end casing is arranged in substantially the same way or manneras to the distance from the vertical end-plateof the stove, and which arc'madeof tinor other suitable material, and combined with the severaLflues underneath the bottom of theo'ven, and which are each for the purpose of prcventingthe escape of beat from that part or portionof the stove over which they are arranged, and to retain the same. at such parts of the stove by theme-ans of such casings, and such space or chambers between the same and the respective plates of the stov'e, n itl.out much reducing the degree of the heat while and during the passage of the same in the flue or flues down the back or rear end of the stove, and under and along the bottom of the oven, forward and backward, to the rear ml, and up the same towards the exi-bpassage thereof, thus and thereby greatly facilitating the operation of be ngby such economy and saving of the heat in its passage through such flue 01' fiues, in the manner and by the leans substantially as herein described and set forth. I Italso consists in the arrangement of a fire-hon or chamber of combustion, containing a firegrate, ai an ash-chamber underneath the same, and the whole suspended inthe even of a cooking-stove, with the front id lower part thereof extending forward and below the same, and in combination with the front doors, which o1 an in the front of the front plate of such fire-box or'chamber of combustion, and also opening into that part t portion. of said oven under the 'said'fire-chamber, fire-grate, and ash-chamber, so arrangedand'suspended, in the manner and for the purposes substantially as herein dcscribedand set forth. '7
It also'consists in'the employment and arrangement of a corrugated plate, for and'forming the top part or portion of the oven of a cooking-stove, projecting upward and back of the fire-box or chamber of combustion,
'It also consists in the employment and arrangement of a damper in" the front of the oven, and within the hearth ofa cocking-stove, and imcombination with the flue or fines in the bottom and underneath the oven thereof, in the manner and for-the purposes substantiallyhs herein described and set forth. I I It also consists in the arrangementbf' a damper within the flue or fiuesof a'cooking-stove, (as the case may be,) so that the heat or escaping heated products of combustion, which arise from. the burning or consumption of fuel in .the fire-chamber or fire-box of a cookingstove, may be're'versed, or thrown from direct entrance into the chamber immediately below the reservoir or water-tank, and' consequently from direct action upon such reservoir, until after such heat or heated escaping productsof combustion shall have been circulated in and through other parts of such stove, and thereafter admitted to and into such'chamber, underneath said reservoir, thus andthereby'warming or heating the water therein, and heating it to-a much greater degree-when, by means of such damper, the said heat or escaping heated products of combustion beadmitted directly to and into such stantially as herein described and set forth. y
In the accompanyingjdrawings, a representsthe firebox .or chamber of combustionfin the front end of the cooking-stove, as well as in thefront and upper corner of the oven 2', and it extends entirely acrosssaid front contains a hie-grate, r, immediatclybelow which there is situated an ash-chamber. 'llieisaid fire-grate may be of that kind which will vibrate or shake in or upon a horizontal line or plane for thepurpose of relieving the burning coal from ashes, or other impcdimcnts,",or the fire-grate may be so constructed as not only to vibrate and shake, but also to dump or revolve over and bash for the purpose'of removing ashes from the fuel in the fire-chamber or to relieve suc'h fire-chamber of and from the contents thereof intothe ash-chamberbelow, or
a fire-grate, whichwill not dump but-which will shake and vibrate'upon a horizontal line or plane.-
It will be seen that in any event asui able fire-grate and ash-chamber immediately below are required suitable mechanical means within the front and upper corner or part of the'oven z with a portion of'said oven extending under the whole arrangement aforesaid.
At one side of such cooking-stove, and of course at and in one 'endtof said fire-box or chamber a, I construct and arrange the damper L, which is for the purpose of regulating the supply of atmospheric air required to start and to continue the combustion of the fuel'in said fire-chamber. Said damper may be of any capacity The front plate c of the said firc chambor may be of, any form or shape desired and nrranged as near to BEST AVAlLABLE COPY the front plate, d, of the stove as may be deemed necessary in order to give suflicient capacity to the chamber or flue A, which chamber,'A, is for the purpose ofreceiving,containing, and heating the airentering therein through the apertures x in the fro nt doors is and before it'enters tlie'oven 2', for the purposes herein described and set forth.
The bottom plate e, below the said fire-box or chamber of combustion a, and the vertically-inclined plate fund the plate g forming the under side of thefiue h, leading from the said combustion-chamber a to the rear fines of the cooking-stove, constitute and form the upper portion, covering, or plate of the oven The said plate g is corrugated iii the manner substantially as shown at g, fig. 3, sheet 2, of the accompanying drawings, and marked fig. 3 It is so corrugated for the purpose of giving more or greater surface for heating or baking purposes in the oven below when heated by the passage over the same of the heat or escaping heated products of combustion, or by said corrugations a suitable amount of ashes may be retained upon the said plate, so as thereby to retain within the oven below for a much greater length of time, such heat as may have been thrown therein by other means and plates, and which corrugations in either case are of great utility.
Along the front part of the said plate g and at or near the platef of said fig. 3, I construct apertures of sufficient size and number to allow of a good and suiflcient ventilation of said oven, while at same time the heateda-ir escaping from said oven through such apertures will come into contact with the highly-heatedescapin'g produ'ts of combustion passing from said firc-chambcr over said corrugated platc, and such gases will thus and thereby become ignited and of course economize in the use of fuel in said stove and at the sometime aid in a pro qr ventilation of said oven, as aforesaid stated.
H Thc said platc c not only forms proper covering for that part of the oven that extendsundor the said firec} mber a, but it also formsthc lower plate of the ash-pit or chamber H between said plate and saidfire-grate a and through which plate passes the heat reflected from the firs upon said fire-grate, and thus contributing omewhat toward baking purposes.
The said oven, 1', has a door or doors, j, upon each side thereof, of suitable size, and properly attached to the stove-plate in the-usual way by means of. hinges, and the same are for access to said oven.
The said even,- unlike any other cooking-stove, has an opening in the front thereof, for the purpose of using therewith one or two or more doors, if found expedient topse more than two such doors.
7 It represents such front doors, in the front end of the said oven, as wcllps in the front of said stove, and it or they may'cxtend upward to or nearly to the top of .the fire-chamber or chamber of combustion, or it or they may extend up no farther than to the under Side of the said ash-chamber, or to thesaid fire-grate within said fire-chamber or chamber of combustion a, as the case may be, or require, for, and because this part of my said invention and improvements in such case would be the same in principle and operation.
When such doors are thrown wide open, and a tin or other suitable roaster is placed in front of the said oven (thus opened into) on the apron Z, the heat radiated by the several plates into the oven 7,, as aforesaid, will roast or bake-such things as may be placed into such roaster for that purpose, while at thesame time the said heat will be retained in the said oven, so that the process of baking may at the same time be therein going on. The said roaster, forthe time being, closes up the said opening or aperture in said front part of such stove, and produced by the throwing wide open or removing of the said doors or door, k. v d
When said roaster is removed therefrom, there being no longer further present use of the'same, in the manner substantially as aforesaid, then said door or doors, 7:, are closed, in order to close up such aperture or opening made as aforesaid. I
' The said roaster may be of any suitable material, and of any form or shape desirable. It must, however, be of suflicient size to receive the open space caused by the opening of said door or doors, as the case may. be, and it may be securely fastened in front of said open space to'the main part of the stove, in any convenient manner, for and during the use required thereof, so that the radiation or radiated heat from the said front plate of said fire-box or chamber, a, or from said fire-chamber itself, maybe used for the purpose of roasting or cook ing such things as may be placed thereon for that purpose. v
The said roaster is portable, and therefore may be attached to or detached from the said front of the cooking-stove, at the pleasure of the operator. This is mosteonvenient, as well as quite useful, as will be found upon a trial or use of such roaster, so arranged and combined, to and with a cooking-stove. p
' The said front door or doors, opening'from the said even, and from in the front of the said suspended firechamber, fire-grate, and ash-pit or chamber, will also be found convenient and useful in the-livarming'ef -the room, when said stove maybe used in very cold weather, as well as convenient in the management offthing's within said oven, which are there being baked or roasted. 7
It may sometimes be deemed best or cxpedicntto put a plate, extending from the front plateof the fire-box and ash-chamber downward to the bottom plate of the oven, containing suitable openings, "or it. might have or contain a damper, or more than one damper at or near the bottom edge of such plate, or near to the bottom of the said even, which shall open from said front doors into said oven, and such plate may bedetachable and removable, or it may be m ade stationary in such position, if deemed best so to do, as the damper or dampers, or openings" aforesaid within such plate, would admit of the passage and cntrance 'of the air, which should have been heated by coming into contact with the front plate of said fire-chamber as it enters through the apertures x, in the manner herein set forth, into the said even, i, for the purpose of aiding in'the-baki ng process, sub
s'tantially as herein set forth and described.
The invention and improvements, so far as relates to that part or branch, would be substantially the same in principle and operation, there being only a mechanical change or variation in the construction, without changing in anyivise the real and material invention and improvements.
In case there be used such additional plate containing suchdamper or dampers, or openings, it would as a matter of course, be arranged at a small distance from said door or doors in the front of said stove, thus and thereby forming a sort of space or chamber between it and such doors, and extending upward to thatchamber,
between said'front fire-chamber plate and the upper portion of said front doors, and which is herein described and set forth. p
The upper edge of such additional plate, which is represented by dotted lines at R, fig. 3, sheet 2, of accompar ying drawings, would, ofcourse, connect with the lower part, edge, or portion of said fire-chamber, as seen u at said fig. 3, and extend entirely across the front part ofsaid'oven. If it contained a damper or dampers, as" aforesaid, they would remain open, more or less,while and during theprocess of baking orroa'sting'in said even, and would remain closed when and while such front doors are thrown wide open, so as to aid in the'th'rowing of. heat into the room from said plates of said fire-chamber, in order 'to warm the same, as and in the manner aforesaid. v
The top flue It extends from the upper part or portion of the fire-chamber. a .over and upon said t'opplate, g, of the oven 2', and to the vertical line or dues in the rear end of the stove. -In or near the central part thereof it opens into an. exit-flue, on, or chamber, underneath the reservoir or water-tank c, all of which is described and set forth in detail in another specification, in another division of theinvention, of even date herewith. v
The passage of heat into said chamber mfiom'said line b is through an opening or aperture governed by adamper, 7t, which-is opened to kindle or start the fire, or when it is not desired to heat theoven for baking purposes; but when closed-tire top-flue discharges into one or more diving-fines, a, at and arranged in a vertical position within the rear end of the stove, and which flue or fines discharge into corresponding'oncs in the bottom of the stove, andjust below and in proximity to thelbottom-plate T of the oven-i, represented at ofthe accompartying drawings, and passing the heat or theescaping heated products of combustion along such flues-to the front end of the same, the same-is discharged intoone or more return-fines, q, placed between such other fines as aforesaid, and passing back to the said vertical flue or flues m, and known as ascending between the diving' or descending-ones, described as aforesaid, and which open and discharge into said chamber underneath said .reservoir, as aforesaid; thenceinto the direct exit or chimney-pipe or flue-tube.
The bacltand bottom of said fines are made by the oven-plates and back-plates, s, and bottom-plate. t. ot
the stove, with suitable partition-plates, substantially as shown in the accompanying drawings.
The said vertical fines, and lines within the bottomof said stove, are each and everyepclosed within and by the means of a covering or encasement, made of tin or other sheet or suitablemetal, placed at a proper distance from the cast-iron plate'of the bottom or of'the end, and that covering or choosing the vsrtical'endlines is represented by a, and thatof the bottom of the stove by v, of the accompanying drawings. Idenominate the said coverings or encasemeuts, respectively, ascxtra back and extra bottom. The space or chamber between said extra back and extra bottom may be of any capacity deemed best, and'they may each be fastened to their respectiveparts of said stove by any convenient and effective mechanical means, and may be so constructed and arranged as to bedetachable and removable. from the said stove whenever it is desirable to prevent the heat from being radiated into the room, and to retain the same in and within the said back and bottom cast-iron platesfas well as within the tines of the stove, for baking, roasting, *or other purposes, then I use said extraback and extrabottom coverings or encasements', which are very useful and desirable for use in the warm weather, or summer-.time of the year, as the same will, of course, prevent the escape jof such heat from the stove through said cast-irou plates and into the room when the stove is being usedJ I prefer to make such encasemen'ts or coverings out of tin, as the same is more effective in retaining the heat, in the manner aforesaid, but'other sheet metal may answer the purposes required aforesaid.
The said=back encasement u is. so constructed as that the edges thereof shallclose'l-y fit to the surface of the stove, and with a flange-at the top, which en-ters un'der the cleat w on the under surface of the bottom-plate of the exit-flue chamber m, fig. 3, and is the n lfirmly held by the pin 1 or any other means or device which will answer thepurpose 'requircd may, of course, be used. i
The said extra bottom or encasement, 1), base, rim around the entire upper edge, which fits up and against the bottom plateof the stove, so that there shall be no escape of the heat'within the chamberforutedbetween said iron stove-plate of the bottom and the said encasement, and the'same time firmly securing'suc'h extra bottom in and toits proper place by bolts or pins passing through the edges of the-staples on the bottom plate of the stove, or any other sufiicient and suitable mechanical means which will answer the purposes desired may be used.
2 is a lip of hasp oueach side of thestove, which fits one end upon the staple z,- figs. 2 and 7, made to cor- .respond thereto, and through which staple passes asuitable pin 'ai'tcrthesaid hasp has bcen placcd thereon, for
the purpose of securing the said extra bottom to the stove, substantially as aforesaid.
There may be more than one such hasp andflstaple, with pinarrangedtherewith, upon either side of said extra bottom So may the respective ends thereof be fastcnedfor secured to such stove, if deemed necessary so to do. A v i As I have hereinbcfore stated there may be, thereis .auainspaee or chamber between'the said extra bottom and extra back plate and therespectivebottom,plateaud 'end 'ver tical end-plate of the stove, so-that'the air within 'such'spacc or chamber so constructed and arranged tetr gand, shall act as a non-conductor, and thus aid in the preventingof the'fradiation of the heat into the room where thestove may be used, and thereby retain the heat much longer in the overrfor baking, roasting, or oookingpurposes in the oven and upon other parts of such cooking-stove, by means of which there will of course be a very greateconomy in the useof fuel at all seasons .of the year I v i It will now be seen that the employment and arrangement, as aforesaid, of said extraback and o f saidcxtra bottom parts or encasements, have a twofold purpose, to wit, first, to prevent the radiation'of heat into the room where such stove is being used, which is very desirable, especially so during the summer months, and
second, to retain-the heatinv the stove-and oven, whereby roasting,,baking, or cooking is carried on in the'most perfect manner with great economy in the use of fuel.
Tho doors of the oven I also line with tin in the sheet, which I fasten to each rcspectivedoor in any substantial manner by suitable mechanical means, which lining'is for the purpose of preventing the escape of the heat within the oven by radiation or passing through the cast-iron doors. There may or may not bea space or chamber between such linings and such cast iron doors of the oven, for in either case the said linings will contribute largelyto retain the heat aforesaid. i
The top plate B of the stove extends back over the exit-flue space or chamber at, and besides the usual boiler-holes, it has alarge hole, E to receive a large boiler or reservoir, (to contain-water,) c, which has two ides, d cl, which pass through the bottom, one near each side thereof, and they run upward obliquely through and to the top of said boiler or reservoir, where they unite in one, substantially as seen, 0, in order to connect with the usual stove exit-pipe or chimney, in the manner substantially as shown at fig. 5 of the accompanying drawings. I As the heated products of combustion enter the flue-space or chamber in from the middle back, they must spread outward in such chamber, and act'uuder and against the bottom part of said belief, in order to get to the two flu'es d.0l in' the bottom of such reservoir, through which they ascend to the pipe upon the topplate of said reservoir. The said boiler or reservoir 0, as, shown by the-drawings herewith, has a removable or hinged cover, thus allowing easy access to and into the interior thereof, for thcsupply or removing of its contents, and also for the making of such boiler closed or tight, as occasion or use may require. .The said cover being thus hinged, it is manifest that the water or condensed steam which may have gathered uponv the under side thereof by means of the heating of the water therein, will drip from such underside of such cover where the same is turned upward, into the said reservoir or boiler c, and of course prevent the same from'dripping upon the floor of the room where such stove is used. But bysuch arrangement of the'h-inged cover, with its lower edge hanging directly over the opening of such boiler or reservoir, the water accumulating upon the pnder side thereof in any manner whatever, is returned to the water in said reservoir, when and after said cover is opened by and upon the hinge or hinges, substantially as aforesaid. Such cover may be of courseconstructed in one or more parts, each of which will be hinged substantially as aforesaid, which of course is not only convenient, but very useful. r
The heated products of combustion not only act efficiently against the entire bottom of said reservoir, but upon the in'sidethercof, through the aforesaid inclined ilues, which have their heating-surface increased by being thus arranged upon an inclined line orposition, so as to form the single connection with the chimneyexit-pipe, in the manner substantially as aforesaid, which inclined tubes may be-cf any capacity or shape deemed best for the purposes aforesaid.
The front plate a of the fire-box or chamber of combustion may be smooth and of an even surface, or it may be corrugated, as shown at c, fig. 7 of the accompanying drawings. It may be constructed 'upona straight line from the bottom edge to the top edge thereof, as shown at said fig. 7 or, if deemed best, it may have any other suitable and required or desired form across the said width of the same. Thesaid plate 0 extends entirely the full width of said oven or stove, and, of course the full length of said fire'chambcr or combustion-chamber a, as it forms one side plate thereof, as aforesaid. 4
Between the said plate a and the front plate d of thestovc, above the front-doors 7c, -or by means of said doors themselves, is located a hot-air flue or chamber, A, fig. 3, and hcreinbefore'mcntioned and described. The said flue or chamber A extends entirely acrossthe stove, and is of any capacity desired, and thereafter opens at the bottom or lower part thereof, dircctiyinto the frontpart of the said oven 2', at or near the bottom plate a of the ash-pit or ash-chamber, or at the lowerpart of the ire-box or chamber of combustion, as the case may be.
The atmospheric air enters the said chamber through apertures :r, figs. Q and 7, and coming into contact with the said plate in front of andforming said firebox, as aforesaid, is heated within said chamber-bottom, such plate, and such front doors as it passes downward the same, to the bottom thereof, to wit, the chamber A and A, where, and at such lower part, said air, in a highly-heated state or condition, enters the said oven 2',
through which oven such heated air passes to and out in and through suitable openings or apertures, as shown at y, fig. 8, and which are in the back plate in the back part orback end of said oven. Such apertures may be of any size, shape, or number, at any desired place or point sufficient for the purpose of'ventilation and baking purposes. 7
It is quite manifest that apertures for the purpose of ventilation, as aforesaid, might hear-ranged in and through the other plates of said even, at such points therein as will allow the escape to be had into a flue pass- :ing some part or portion of the oven. -In this manner or substantially so, the oven is supplied by and with a fresh and continuous current'of heated air, that shall not only contribute largely in the process of baking or roasting, but at thesame time cause the said oven to be thoroughly ventilated of any and all foul or unwhole- I some matter that may arise .by reason of baking, roasting, or cooking in and about said oven z','a thing thus accomplished and of great importance in the use of such oven, as aforesaid.
' The capacity of the apertures so should always be greater than that of the said apertures y, so as to always maintain sufiicient heat in the oven for any purpose that may be required, while at the same time said oven is sufliciently ventilated, and the continued current of fresh heated atmospheric air is always sufficiently hot to aid in the process of baking, roasting, or other cookingwithin said oven, substantially as aforesaid.
If desirable, the said oven front doors k may not extend upward as high as shown in the accompanying drawings, but may extend no farther upward than to the lower part of the ash-pit or ash-chamber, in which case the front plate (1 will extend, and continue downward far enough to meet the upper end of the said front doors k, which would of course open into saidoven, and would cover allthat space'or part of said oveui which extends forward under the said fire-chamber, fire-grate, and ash-chamber,aforesaid, producing the same effect-and same results as would be the case when such doors continue upward, in tbemanner as hereinbefore described and set forth. In case of the short doors, as aforesaid, shall be constructedland used, then the said apertures 22' would be made through the'sa-i d plate cl,,instead of through the said doors It, as hereinbefore set forth.
Thc'principlc and the operation would be the same in either case should such apertures x be made at or near the lower part of the said hot-air chamber, A A. Then would there be required a partition-plate in saidchamber, extending the whole length of said chamber, and upward from the bottom far enough to cause theair to pass upward and over the top of the same, and against and down the said plate of said fire-box or chamberplate, 0, figs. 3 and 7, and thence into thesaid oven, substantially as and for. thcpurposes aforesaid. The said hot-air flue or chamhcrpA, may be of any capacity'desired, and at the same time carry-out the design or object of the same; and in case a plate is constructed and used in the front part of said oven, 2', which shall commence upon the bottom plate of the oven, and be carried up to the lower part or corner of said fire-box, or ash-pit, or chamber, with damper or dampers therein, and shown at, W, 3, in the manner substantially as herein described; then the purposes, the working, and the operation of and'in said chamber, AA, will be the same. The heated air would pass downward in such case to said damper or dam pers, and through and by means thereof enter said oven for the purposes aforesaid, substantially as herein described and set forth. It will now be seen that the saidcbamber A A answers a two-fold purpose, as follows, to wit: First, the air entering therein is highly heated, so as to faeilitatebaking in the said oven, in the manner as aforesaid, described'aud set forth; and, second, the cold air entering therein comes into contact with the front plane and thereby prevents the two rapid heating, andjhereforc burning out, of said plate, and while descending the said plate, becomes heated auflicient for baking purposes when it shall have entered the oven 1', in the manner substantially as aforesaid,
The front part of the said oven opens directly into the said roaster supported upon the hearth and in front of said stove, in the manner substantially as herein contained. The said front doors 7L, being thrown wide open for the purpose of permitting the heat to pass into such roaster from said oven, as herein specified, the operation cr'process of roasting or baking therein, to wit, in said roaster, or additional, detachable a'nd'removable oven, goes on in a most perfect and satisfactorymannor. When the said front doors are open, and no roaster oradditional oven is placed thereon and therein as aforesaid, a large amount of heat .is radiated or thrown into the room where such stove isused, from said oven, and from said fire-chamber suspended in the front-part of said oven, as aforesaid, which, in cold or winter weather is quite desirable-especiallyso when the oven is not :in use for baking or roasting purposes.
At ,Y, figs. 1, 2 and 3, alsofig. 7, is a damper, which opens into the flue or flncs immediately under the bottom plate of the oven of the cooking-stove. The said damper may be of any size, shape, or capacity required for the purposes intended. The damper-openingmay be seen at Y, fig. 3, where it is shown to be in I and through the top plate of the hearth impact, and in part in that part of the front plate of the stove which is immediately below the said front doors is.- .It-, however, may be either in the plate alone, or in both, as there shown, so long as it opens into said flue or flues below and underneath said oven 2'. Thc said opening is covered.
with a suitable and corresponding piece of cast iron, which I denominate afront hearthdamper or valve, Y, and which is for the purpose of checking and aiding in the controlling of the circuit or' circuitous draught of the heat when thrown on by means of'the damper n, figs. 3 and 4, which cuts oil the direct draught by pushing the same inwards by means of the rod attached thereto, and extending outwards from thc'stove, as showuat figs. 2, 4 and 7, for it closes the direct exit-flue space 0, and directs the heat. and escaping products of combus- .-tion into and downthe flue or flues leading to the flue or flues in the. bottom of the stove, and directly under heath the bottoui plate of the oven.. By partially opening or removing said dampei Y from its place in the hearthor front part of the stove, the draught aforesaid will be controlled as desired by the person using the stove. So also may the ashes, soot,.or other matter within the line or lines i'nthc bottom of the stove and underneath the oven be removed therefrom through such damper-opening, by some suitable instrument or'tools constructed for that purpose. V V
The matter pertaining to the boiler or reservoir c,as wellas the warming cl'oset underneath such reservoir, and each and every part of the said cooking-stove in anywisc connected tlicrcto'andtherewith as'a part thereof, in order. to carryout the invention and improvements thereof, have been and are described and set forth in a specification of even date herewith, and which may be known as the second division of the reissue of the patent 'hereinbef'ore set forth, and, of course, the same need not be described-in detail and at largein this specification of the reissue, division the first.
