COOKING-STOVE.

Specification of Letters Patent No. 21,518, dated September 14, 1858.

T 0 all whom it may concern:

Be it known that I, AroLLos RICHMOND, of Brooklyn, in the county of lVindham and State of Connecticut, have invented certain new and useful Improvements in Cooking- Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view; Fig. 2 a longitudinal vertical section through the middle of the same; Fig. 3 detail to be referred to hereafter.

In cooking stoves as heretofore constructed two of the boiler holes are over the fire pot, the other two being placed over the oven plate and receive the heat of the fire only as it passes on the way to the flue, over these latter holes the common wash boiler cannot be placed, as the heat at this point will not be suflicient for a large boiler, and the top plate would be too much weakened if cut away between the front and back holes to accommodate the oval boiler at the side of the stove. Were the fire pot to extend beneath all four of the holes it would be entirely too large, and the oven would be thrown too far off, and the size and weight of the stove as well as its cost would also be greatly increased. In cooking ranges the desired end is gained by placing the boiler holes in a line, the two upon the extreme ends receiving the heat directly from the fire pot which is beneath the center holes; such an arrangement would obviously not answer for a cooking stove as it would too greatly extend it in length.

My invention has for its object to bring the four boiler holes as near as possible over the fire pot, without throwing the oven to too great a distance from the fire, and without materially increasing the bulk, weight or cost of the stove. and my invention consists in giving to the front of the oven a curved or projecting form, and in combination therewith in arranging the boiler holes around it and extending back under it in a curved form. the fire chamber whereby the four boiler holes as well as the oven are brought into the immediate vicinity of the fire, and a stronger construction obtained without increase of bulk and the fire chamber rendered capable of more readily accommodating pieces of wood of irregular forms.

That others skilled in the art may understand and use my invention, I will proceed to describe the manner in which I have carried out the same.

In the drawings A is the body of the stove having fire doors a, and b.

B is the hearth, G the top plate furnished with boiler holes 1, 2, 3, 4:.

I) is the oven, part of which at c projccts toward the front of the stove and rests on the plate G, the holes in the plate being arranged around it.

The bottom of the stove extends back at (Z and forms a convenient place for keeping things warm; from the rear end of this rises the plate 6 which supports the oven casing. The tire space occupies the whole body A of the stove and extends back partly beneath the holes 1 and 4; whence the flame communicates as indicated by the arrows Fig. 2 with the space f beneath the oven, where it circulates freely and unobstructedly between the plate 9 and the bottom of the oven; thence through the space It at the back of the oven to the top part of it, where it is divided by a supporting plate 2' which extends across the middle of the passage h and serves to attach the interior lining k to the exterior portion or casing Z at this point, while they come together at m at the front.

From each side of the plate 11 there extends toward the front in the space between the top 76 of the oven and the casing Z, a dividing plate a, which also serves partially to support the oven; these plates (which extend but part way to the front) deflect the flame or heated air which passes from the space it in two columns over the top of the oven, and between these plates and the outer casing, until it arrives over the front part of the oven, where it meets a central dividing plate 0, which extends from the front up toward the center of the oven easing between the plates at. This plate 0 turns the currents (as shown by the arrows Fig. 3) up between the plates at and it passes out at the smoke pipe 77. The oven is thus surrounded on the bottom, back and top with the flame or highly heated air. Another boiler hole 5 is placed in the crown of the casing Z over the flue between the plates n. This arrangement of the fire space has many advantages. VVheu used for wood sticks of a greater length, or of a more irregular form can be used than in the ordinary stoves, while all the boiler holes in the plate C are over the fire itself, and not as is usually the case, over the flue leading from the fire, in which arrangement the rear holes are not often used when anything is required. to be cooked quickly.

The wash boiler is generally made of an oblong form intended to occupy the space of two boiler holes, a portion of the plate 0 (as in red at 1 Fig. 1) being made removable for this purpose; in the common stove this can only be done between the two front holes, as the central portion of the top plate would not be sufficiently supported if the portions 7" on the sides were also cut away; but in this form of stove, as the part c of the oven projects over toward the center of the plate 0 and serves to support it, the portions 0 on each side may safely be made removable, and the wash boiler may occupy its usual position on the front, covering holes 2 and 3, or a place on either side of the stove, covering holes 3 and 4 on one side, or 1 and 2 on the other; this facility for changing the boiler will at times be found to be a great convenience. The projecting portion 0 gives additional oven space without sacrificing the room required for the boiler holes.

The rear part of the fire pot A of the stove is curved inward forming a recess at s Fig. 2 beneath the part c of the oven, this makes a convenient place at the back of the fire pot to set things to warm, or if required this space may be occupied by a water back.

As in this stove there are no valves or dampers to be arranged to divert the flame to the top or bottom of the oven, careless or ignorant servants will not make the mistakes which so frequently occur of setting the dampers in the wrong position.

It is obvious that the form and arrange ment of this stove may be varied without departing from the spirit of my invention, for instance. The portion 0 of the oven may be made broader or nearer to a semicircular form, and the boiler holes to any convenient number be arranged regularly around it, or if less space is required it may be contracted, and the holes 1 and 4 be brought nearer to each other. e

The space back of the fire pot between the bottom cl and the plate 9 above it, may be made to be shut up close with doors, (dispensing with the perforations in the plates (Z and 6 shown in the drawings). The bottom (Z behind the fire pot may be dispensed with, and the back part of the oven be supported directly from the fioor by suitable legs or supports.

Instead of an elevated oven as described, the stove may be made with a fiat top and the oven may occupy the space back of the fire-pot between the bottom (Z and the top plate of the stove.

I am aware that a stove was patented to J. Curtis Jan. 27, 1843, in which the oven projects forward in a rectangular form having the boiler holes arranged around it; but consider my improvement as differing from said stove; since my oven projects forward in a curved form, and since my pic chamher is also of a curved shape, while that of Curtiss stove is rectangular. I do not however lay any claim to either the form of oven, or fire chamber separately, or to such construction as embraced in Curtiss stove, but- What I claim as my invention and desire to secure by Letters Patent is:

Extending the oven forward in a curved form and arranging around it the boiler holes as set forth; in combination with the curved pie chamber, the whole being constructed and operating as described for the purposes set forth. 7
