To all whom t 'may concern: 1 Y,

Be it known that I, `1\TATHA1\`HE L A. BoYN.- TON, of the city, county', and State ot' New York, have invented an Improvement in Cool;- ing-Stoves, of which the following is a specification: A Y l The invention relates,iirst, to an ash-pit extending under the oven, in combination with a supplemental oven or warming-chamber, separated from the said ash-pit by a suitable partition; secondto a pert'orateddivsion-plate, separating the ash-pit and supplemental oven; third, to the construction of a cooking-stove or range with an ash-pit in the base or lower part, surniounted by a deiiecting plate or ping through the grateto fall into anasll-pan placed within the ash-pit; fourth, to a gravitating door of peculiar construction, for clos-` ing a poke-hole or draft-aperture.

In the accompanying drawing, Figure 1 represents a vertical section of my improved stove in the plane w a: in Fig. 2. resents a vertical section in the plane y y in Fig. 1. Fig. 3 is a view of the exterior ofthe door E and of the 'tail-piece. Fig. et is an inside view of the door with the tail-piece.

This invention relates to cooking-stoves; and consists in several features of improvement, as hereinafter described, and as shown in the drawing.

r[he letter A designates the stove, which may be made of anyr desired proportions or shape, provided the principle ot' my'improved construction and arrangement is adhered to. The top of the stove is provided with boilerholes, which can be conveniently arranged without crowding, because the exit-flue is made to leave the stove at its side instead of The letter B designates the tirechamber, Whose grate C is revolved in the usual manner by a wrench applicd'to the end Below the level of the grate C is an opening or poke-hole, D, in the wall of the (ire-chamber, the object of which is to allow a poker to be inserted below the grate, to clear it of ashes and cinders by that means. The opening D is closed by a balancing-door, E, which is seen in edge view in Fig. 2, and in front view or elevation in Fig. 3,

plates, which cause ashes drop-A Fig. 2 rep-` and which is so constructed and arranged as to remain either open or closed by gravity without requiring any fastening. said door being made with a tail-piece, F, which is re,- ceived within the stove, where itfswings ory vibrates up and down when the door is opened and closed. The tail-piece F is connected to the door by a horizontal` plate, Gr, which is concave on its under surface, and .forms a shoulder, that rests on the bottom edge oi' the opening D, and allows the ldoor to' turn on such edge, the said plate Gr being made of suoli length as to lit easily between the sides oi' the opening g but that part oi' the door which remains on the outside ot' the stove is wider and longer than the openings,l D, and its edges consequently overlap the sides and top ot' the openino. The tail-piece is also made wider Athan the opening. This greater width of both the door and tail-piece, as compared with the width of the opening D, prevents the door from falling-out oi' its place. In order to re,- move the doorfroni the stove and put it in place again, it is only necessary to-turn it upsidewise, so as to bring one ot' its edges opposite one ofthe upper angles ot' the opening or doorway, when it can be easily pushed in or taken out.

ferent planes, in such a manner that when the door is closed the center of gravity of the parts will fall inside of a vertical plane passing through the line of support of the door, where the hollow or concave shoulder G rests on the bottom edge of. the opening or doorway D, thereby keeping the door up close against the stove. When, on the other hand, the door is opened and turned down to its lowest position the center of gravity is brought outside of the line of support, and the superior weight of the door keeps it down, the edges of the tail-piece abutting against the inside edges of the doorway D, and preventing the door falling away from the stove. Below the grate G is the ash-pit H, which occupies the whole space between the grate G and the bottom plate l of the stove, but has, at any convenient height, a plate or plates, l?, leaving a central opening, through which ashes dropping from the iirechamber will be concentrated, so as to cause FFICHEg Ytary oven within the y. feet them,

them to fall within a movable tray. or,.ash-pan, J, Iwhich `is kplaced in the ash-pit to receive them.' Y The ash-pit H readily receives an ashpan, J, of sucient size to receive the whole contents of the fire box or chamber B. 4The tray or ash-pan J vis removed and replaced through the doorway K.y The oven L is di# rectly behind the Afire-chamber, and is so ar-Y ranged that its bottom plate is below the level of the grate C, whereby some ofthe heat which radiates from the tire past the bars of the grate is allowed to act directly upon the front side of said oven. Below the oven L is a warming-chamber or supplemental oven, M, whichY occupiesthe space-between the main oven and the bottom of the stove, and between the ashpit and the back plate of the stove. The division-plate 0, which separates the 'ash-pit 'from the chamber oroven M, may be vprovided vwithholes N, through which any cool air Awhich `gains access to the chamber M willl pass out to the fire by the naturaldrat't ot' the stove.

,The chamber or supplementaryT oven M is provided `with a door on the same side as the usual door' to the main oven L, and the usual dues pass under the oven L and behind it, and connect vwith. the exit-pipe on the sideof the stove.

It will be observed that,by means of my invention,. l obtain, in addition to the main oven, in which the highest heat forbaking is' obtained,a warming-chamber or supplemenwalls of the'stove,in which chamber I can place articles that are removed from the main oven, and which require only a moderate degreecof heat to per- While the main oven is continued in use for baking with full heat, thus doing away with any necessity for opening the oven in order to perfect its contents under a less degree of heat. The chamber M cany also be used tobringarticles to a moderate degrec of heat, and also to warm the apartment, When the door ofthe chamber is left open.

It will also be observedthat, by means of the construction and arrangement here shown, a considerable part of the large amount of heat which is found in the ash-pit is saved or utilized by being communicated to the chamber M through the division-plate O. The chamber M can also be used for the ordinary purposes of a hot-closet, and it can also be used,as ameceptacle-ifor coal `or. other fuel,any gases-.,which'may be igenerated therefrom by the gentle heat being allowed to escape through the holes N into the ash-pit and dre-chamber, where they will be burned. It may also be used for drying kindling or other wood and other articles, and for any other purposesto which a hot-closet may be put.

Several advantages result from extending the ash-pit under the oven. Of these I mention three: first, it aiords a large roomy ashpit, and permits the use of an extra-large ashpan under the grate without boxing out the end of the stove; second, it aEords-space for allnecessary appliances for providing a free draft through the ash-pit without obstruction Vfrom the accumulation of ashes; third, a large roomy7 ash-pit enables theair-to be partially heated before passing `through the `burning fuel, producing a more-quick and thorough combustion.

Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent:

l. The extension of the ash-pitr under the oven, in. combination with the warming-chamber or supplementary oven at the back or side of the ash-pit, separated therefrom by a perforated or other partition,substantially as and forthe purpose specified,A

2. The perforated division-plate O, which separatesthe ash-pit H from the supplemen tary oven M, substantially as'described.

3. A cooking-stove constructed with a baking-oven, a warm-closet, M, beneath it, a deep ash-pit, H, separated from the warm-closet by a partition, 0, and.. a delecting plate, (or plates,) P, placed above the ash-pit and below the grate, substantiallyl as and for the purposes set forth.r

4. The balance-door E, provided with a shoulder, G, which forms its -point or line ot1 support, and a tail-piece, F, which aids in operating the door, substantially as described and shown. f
