This invention relates to crtainnovel improvements on that class of cooking-stoves or'ranges wherein fuel is supplied to the fire-chambers from reservoirs-or;

magazines, upon the principleof the well-known base: burning parlor-stoves.

Previous to the invention which we shall hereinafter describe, cooking-stoves have been constructed with fuel-magazines arranged in various ways, some of the magazines being wholly outside of the outer walls of the stoves, andsome being arranged partly within the. outer walls of the stoves. -In some instances the;

vmagazine, on top of and exterior to the top plate of the stove, that two of the boiler-holes through said plate can be brought wholly orpartly over the'firebox, so that the bottoms of vessels applied in or over said holes will be subjected to the direct action of the fire, without interfering with the feeding of thefuel to the fire-box. It also provides for obtaining a direct outward draught into the smoke-flue from the fire-box, when desired; andwhen such draught is closed, provision is made for conducting the products of combustion-over and beneath the oven of the stove, the air being admitted beneath the giate of the-fire-box, and, when desired, it can be also admitted into the fire-chamber from above the same, as will be hereinafter explained.

The invention further provides for preventing the accumulation of gases and air above the fuel in the magazine, by having a conduit leadingfrom the upper portion of this magazine down into the fire-chamber;

* and in conjunction with this feature, provision is made for allowing air or vapors, rising from the top of the stove .while cooking, to'euter said conduit, and be conducted into the fire-chamber in jets, as will be hereinafter explained.

The invention iurther provides for the use of a waterback for warming water,-in conjunction with a magazine or base-burning cooking-stove; also, for the use of a sliding and tilting grate and an ash-sifter, whereby the grate can be kept free from obstructions, and the coal-ashes sifted within-the ash-pitof the stove.

Provisionis also made for the use of a hot-water reservoir and a warming-closet with abase-burning cooking-stove; also, for exposing to view, through transparent substance, the light of the fire in' the firebox and the interior of the oven, so that the doors of said chambers need not be opened to inspect the condition of thingsl in the same, also, for warming air, on its way through the door of the ash-pit, to supply combustion in the fire-chamber, as will be hereinafter explained.

Having thus referred to some of the most important improvements which we have made in base-burning cooking-stoves, we will proceed 'to describe suchimprovements, in connection with the 'accompanyiug draw- 111 s.

fhe drawings represent a stove of rectangular form, with a single oven, around which the products of combustion can be conducted, on their way from the firebox to the main escape-flue J.

The oven is enclosed .on four sides by Walls, B B B. B, and-on two vertical sides by doors, B to which glass or mica windows, 0 c, maybe applied, for the purpose of allowing the inspection of articles in said even without opening its doors.

I Betwee the top, front, and bottom walls, B, of the oven, and the top, fitont, and bottom outer plates, A A A of the stove, is a flue-space, b, which leads from the fire-box D, and fire-chamber above the same, around the oven,-beneath the ash-pit, thence up through a vertical space, .which is between the ash-pit wall and the I back plate A- of the stove, and into and through an Thus it will be' seen that the four oven-walls are exposed to the action of the heated products of combustion on their way from the fire-box to the escapeflue.

Between the oven-plate B, which is curved, as shown in fig. 4, to afford much oven space as possible, and the back outer wall, A of the stove, we arrange the fire-box D and the ash-pit chamber 0; and above the fire-box 1), outside of the outer wall or top plate, .A, we arrange the fuel-magazine E, for supplying fuel to the said box. This magazine is arranged a little back of the centre of the fire-box, as shown in figs. 2 and 4, so as to allow the boiler-holes,lettered D7, to be brought partly over this fire-box, for the purpose of subjecting the bottoms of vessels placed over said holes to the direct action of the fire at the hottest part of the stove.

In order to carry out this arrangement of the fuelmagazine and the boiler-holes, and to obtain a proper horizontal capacity of magazine, we employ at the base of this magazine, E, an inclined plate, D, which extends a little more than half way around said base, and directs the fuel forward into the fire-box, as it descends to supply the same. This inclined plate or skirting D does not extend down to the top edge of the back fire-brick, but allows a free space for the escape of the products of combustion through openings g, into the main fine b, when the sliding damper or valve which is applied to said openings g is drawn back, so as to open the communication. hese openings g afford a direct draught, but when they are closed the products of combustion take the course around the oven, as indicated bythe black arrows in fig. 4, and above described.

The grate (Z to the fire-pot D is supported by trunnions, cl, upon toothed ledges S, so that it can be tilted or turned about these trunnions, and also so that it can receive an eudwise motion.

The openings through the grate may be constructed in any desirable manner, but its ends are toothed, so as to receive between their teeth the teeth .9, thereby allowing of said endwise motion to the grate, without leavingsuch spaces at the ends thereof as would cause too free an escape of the fuel.

One of the trunnions of the grate extends through and beyond the outer wall of the stove, as shown at (V, fig. 5, so that it can be taken hold of to shake or tilt the grate.

Below the grate is a perforated shaker or screen, 0, for sifting the fine ashes from the cinders; and below this ash-sifter is a removable pan, 0, for receiving'the ashes. The handle of the screen is shown at 0 The door 0, leading to the ash-pit (J, is provided with a register, J, for the admission of air to supply combustion; and on the inner side of this door a chamber, p, is formed, which receives all the air that enters said register, and conducts it downward, thereby allowing the air to become warmed before it passes through the grate cl. g

Between the fire-box D and the back wall of the ash-pit 0, there is a space, which leads to openings g communicating with the escape-flue, through which openings the dust and light ashes will be carried off during the operation of screening the cinders. When desired, the openings y can be closed by a valve provided for the purpose.

By means of the stem g and the stem g projecting through the outer side wall of the stove, as shown in figs. 1, 5, and 6, the valves applied to openings 9 y can be conveniently opened or closed.

At the upper terminus of the front transverse fire: brick of thefire-box D is a pipe, j, which lies transversely across the flue-passage l), and extends through the side walls of the stove. This pipe is designed to serve as a means forheating water to be used for various purposes, for which it should be connected with suitable reservoirs, containing water, in a manner common to water-heaters or fire-backs for other kinds of stores. I

The magazine E is constructed with a flue, 1?, down its front side, which flue communicates, at its lower end, with a horizontal transverse trough, T, which is arranged over the fire-box, and thickly perforated, for the purpose of allowing anand gas to issue from it in jets, and thus mix with the highly-heated products of combustion as they rise from the fire-box D.

The upper end of the flue P communicates with a chamber, E, which is above the sliding cover g of the magazine, operated by handle 5%, and conducts downward and into the trough r all air and 'gas which accumulate above the coal in said magazine.

The register E. which is applied to the front side .and outer wall of the magazine E, serves two purposes,

viz, it will admit any desired quantity of air to be introduced into the fluespace above the fire-pot through the flue P and perforated trough 'r; it will also serve to conduct into the flue l) a large quantity of smoke, gas, or vapor which may arise during the process of cooking.

For the purpose of inspecting the condition of the fire in the fire-box D, we make openings through the side walls of the stove, and cover them with inica or other transparent substance, as shown at e e in 'figs. 3 and 4.

The back plate A of the stove is constructed so as to form an enlarged ascending flue, leading to an over,-: hanging chamber, F, over which the top plate A of the stove extends, as shown in figs. 2 and 4.

Through that portion of the top plate A which covers the'extended chamber F is an opening, h, through which the products of combustion escape before entering the pipe J.

.The pipe J passes up through the centre of a reservoir, I, for containing water, which reservoir may be made with double or single walls. By passing the pipe J through the boiler I, a large amount of heat will be utilized, which would otherwise be wasted.

At the back of the stove, and beneath the extended or overhanging chamber F, is a sheet-metal box, H,

which serves as a closet for receiving and keeping articles warm, heat-being communicated to it through the back wall of the stove.

The vertical as well as bottom plates or walls of the stove may be lined with plaster of Paris, a, or some other suitable non-conducting substance. In figs. 3, 4, and 5, we have represented such substance applied upon theinside surface of the bottom plate A, which extends beneath the oven and ash-pit. This lining, a, will prevent, to a considerable extent, the conduction of heat.

from the bottom of the stove. If desirable, the doors of the stove may also belined with some good non-conductor of heat, or they may be made-of double walls, enclosing an air-space, as described, for the warm-water reservoir I, back of the fuel-magazine.

For the purpose of regulating the draught around the 'oven, so as to diminish and regulate the heat of the same independently of the register j, which is applied to the ash-pit door 0 we provide the front vertical wall B of the stove with a register, a, which will allow any desired quantity of air to be introduced into the flue b, to mix with the products of combustion after they leave the fire-box. This register we show in fig. 4.

By reference to fig. 4, plate 2, it will be seen that we have a plate, T, secured to the bottom plate of the oven, just at the base of the curved division-wall B, which plate extends transversely across the flue-space b, and forms a construction of this space, for the pur pose of retaining the heated products of combustion beneath the oven as long as possible without materially obstructing the draught, thereby utilizing the heat,

and confining it where it ismost needed.
