STOVE.

SPECIFICATION forming part of Letters Patent No. 399,767, dated Ivarch 19, 1,889.

Application led January l2, 1888. Serial No. 260,504. (No model.)

To all whom it may concern.

Be it known that I, WILLIAM BAKER INIC- GINNIS, a citizen of the United States, residing at Nevada, in the county of Vernon and State of Missouri, have invented certain new and useful Improvements in Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which Io it appertains to make and use the same.

Figure 1 is a perspective view, partly broken away, of a heating-stove having my inveition applied thereto. Fig. 2 is a perspective view, partly broken away, of a cooking-stove having my invention applied thereto. 3 is a vertical transverse section, enlarged, of the cartridges which I propose to use in the heating-stove. Fig. 4 is a vertical transverse section, also enlarged, of the cartridges which 2o I propose to use in the cooking-stove.

Like letters of reference indicate like parts in all of the gures.

This invention relates to the use of what is commonly known as cartridges consisting,

2 5 essentially, of some fibrous or other absorbent material inclosed in a wrapper, casing, jacket, or net-work adapted to support such absorbent material in convenient shaped and sized packages, which are to be saturated with some 3o combustible material. Prior to my invention such absorbent material has usually been supported upon a stationary grating or other reticulated surface permanently attached to the heater. 3S

out distinctly in the claims hereof.

As illustrated in Fig. I, the stove is of some well-known form-as, for instance, four sides, A A, top B, bottom C, with a door, D, and an 4o outlet, b, for the products of combustion, with a suitable arrangement of draft, d, and,when preferred, a damper in the-pipe.

E c is a cartridge, which by preference has an outer casing or jacket, E', of sheet metal, having upon its upper wall or surface a series of perforations, c c, with corresponding perforations upon two of its opposite sides. as plainly shown in Fig. 3. The absorbent material, preferably asbestus, is shown at e in 5o Fig. l and at g in Fig. y

The nature of my invention will be pointed d d represent a support for this cartridge, which in this instance consists of strips having angle ends projecting inward from the side walls, A A, of the stove, combined, preferably, with a trough, A', having its bottom and side walls perforated, as at d.

G g g represent a supplementary cartridge arranged in the lower part of the stove, the absorbent material g being preferably of asbestus. As indicated in the drawings, this lower cartridge is of such size and form that it can be easily taken out through the door of the stove; but for reasons to be hereinafter explained such construction is not essential to the carrying out of my invention, and therefore I do not wish to be limited thereby, reserving the right to make this cartridge of such size that it cannot be taken out through the door, or, in fact, to make it integral with the body of the stove. As shown in Fig. 3, this absorbent material is arranged below some cross bars or wires g', which at their ends are attached to the sides of the car-' tridge, for the purpose of more effectually keeping the asbestus in place.

Of course, if it is not intended that the lower cartridge should be removable, then these cross bars or wires may be dispensed with.

It is apparent that the holes a in the troughs facilitate the passage of liquid from the upper cartridge directly down into the lower one, whereas were it not for these perforations such material would ordinarily be conducted to the ends of the trough and run thence down an inner wall of the stove-a mode of operation which would be seriously objectionable.

In Figs. 2 and 4 I have shown three cartridges constructed substantially like those of Figs. l and 3, except that the upper cartridge, l-I, has its side wall next to the oven perforated its entire width in order to use the heat more effectively for the heating of the oven, it being apparent that in a cookingstove perforations upon the opposite side of the cartridge would involve a waste of heat. Of course the upper wall of this upper cartridge is also perforated, as at h. The second or intermediate cartridge, I, is, by preference,

IOO

perforated only upon that side wall which is next to the oven. The lower' cartridge, J, is, by preference, substantially like the lower cartridge in the heating-stove, and, like it, may be removable or not, at the will of the operator. In both instances I propose to provide the absorbent material of the lower cartridge with an upwardprojecting tuft-like portion, K, for convenience in setting on fire the combustible material.

From the above description it will be readily understood that my invention may be operated in many ways which differ from any preceding one. For instance, in the heatingstove the upper cartridge may be made quite small, so that a comparatively small. portion of the wall of the stove shall be heated to such an extent as to radiate heat freely, and therefore the stove will be suitable for use in moderately cold weather. Again, such of the combustible material as overflows or drips from the upper cartridge will fall upon and be retained by the lower one, where it can be utilized for fuel whenever required, and when thus utilized will of course increase the heating capacity of the stove, which increase can be largely added to by filling the cartridge with similar material or with different material, as the exigencies of the case may render desirable. So, also, in case the amount of heat produced by the burning of both cartridges should be greater than should be desired, the upper one can be removed, and thus an intermediate amount of heat produced. The same results can be attained in the case of the cooking-stove, with the additional advantage that there are three cartridges used therein, of which the upper one is specially adapted to heat vessels or other cooking utensils placed on the top of the stove, while the intermediate one is adapted more particularly to heat the oven by'reason of the flames being directly against the front wall of the oven, although, of course, part of the heat generated by this cartridge serves to heat the top of the stove or anything placed thereon. So, also, in this cooking-stove the lower cartridge will receive and retain any drip or y overflow from either or both of those above it,

and the combustible material, which is in this manner or in any other manner mixed with the absorbent material, may be burned either for cooking or for heating purposes only. The usefulness of this lower cartridge for adapting the stove for heating a room is greatly increased by its location, it being obvious that for such uses the stove will be rendered much more efficient by reason of this lower cartridge being so near the bottom of the stove.

As there are many circumstances and conditions under which it is desirable to maintain a moderate amount of heat in a stove for bricks of fire-clay or other suitable material adapted to absorb heat from the cartridge during the period 'of combustion, and then give it off somewhat slowly after the combustion has ceased by reason of the exhaustion of the cartridge. This mode of operation is exceedingly useful, not only in the heatingstove, but also in the cooking-stove, under circumstances where the .material which is being cooked by either boiling or baking requires to be subjected for a long time to a comparatively low degree offheat, as is frequently the case. Therefore I prefer in both stoves that these blocks or bricks should be removable, in order to meet all the requirements which will be found under the ordinary conditions of use. By arranging the cartridges in close proximity to the side walls of the stove I insure the heat from them shall be given off by the said side walls of the stove in a much more effectual manner than it would be if they were separated at a comparatively great distance.

Vhat I claim is l. In combination with a stove, a series of cartridges arranged one above another, one of the cartridges being removable, substantially as set forth.

2. In combination with a stove, a series of cartridges arranged one above another, and of which the upper one is removable, and the lower one is adapted to receive and retain material falling from the upper one, substantially as set forth.

3. The combination, with a stove, of the perforated trough, the cartridge supported in the trough, and the cartridge below the trough adapted to receive material ilowing from the upper cartridge through the trough, substantially as set forth.

4. In combination with a stove, a series of cartridges, one above the other, the upper cartridge having perforations in its upper surface and one side of its casing, the second cartridge having perforations in only one of its sides, substantially as set forth.

' 5. In combination with a stove, a series of cartridges, of which the upper one has perforations in the upper surface or wall of its i casing, and also in two or more of the sides of its casing, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
