y cooKINc-'srovrs To ALL WHoM Ir Mar coNoEnN;

Be it known that I, H. STIcKNEY, of Reno, in the county of Venango, and State of Pennsylvania, have invented a new and useful Improvement inA Cooking-Stoves; and I do hereby declare that the following `is a full, clear, and exact desciiption thereof, which will enable others skilled in theart to makeand usc the same,

reference being had to the accompanying drawings, forming part of this specification. y This invention relates to a new and improved construction and combination of parts, whereby I am enabled to adapt the base-burning principle to cooking-stoves; and the invention consists in arranging a base-burning 1 furnace, and by suitable fines conducting the products of combustion to where the h'eat can be utilized for cooking and other domestic purposes, as will behcreinafter more fully described. The drawing, l

Figure 1, represents a vertical sectional elevation' of the stove through the line :v :vof iig. 2, showing the1 arrangement of the furnacel and dues and the air-passages.

Figure 2 is a horizontal sectional view through the line y y ef fig. l. Similar letters of reference indicate like parts.

The cooking-stove proper is represented by A, with the supply-chamber in the centre, markcdB. C is the hearth of the stove. The stove-grate is conical in form, and is marked D. This grate is supportediby a conical frame, marked D', which is itself supported by the upper portion of the ash-box B. There is anash-pan, A',

which slides under the grate upon the hearth, and air is admitted to the fuel through sliding dampers over the f ash-pan` With the exception of that portion of the stove which forms thc hearth, and which portion is open, the furnace is surrounded by acasing which i's composed of circularl slides, by which an oven, C', is formed i around the furnace, access to which is obtained by the slides before mentioned. One of the slides is seen at a.`

The bottom of the oven is marked c. b is a grate or rack in the oven. Provision is madelfor the admission of airby holes through the slides, as seen at d, which air passes up through the oven, and into the air-passage e. The smoke and products 'of combustion pass from the furnace upward through a flue, markedf.

The ilues and passages for both smoke and air are formed ofconccntric cylinders, asreprescnted in the.; A

drawings; consequently thc'ilues' are anular in form, or in their cross-scction,` andV extend from thc upper` plate, or surface of tho stove, to the bread-oven, which is marked E.

The arrangement for boiling, or the ordinary kettle-holes of thc cooking-stove, are through the plate F.`

The products of combustion arc -brought in direct contact with t-h-qukottles, and may be made to pass to the 1` outer edge of' thestove, and from thence into the iluef, under the top plate Frbctwecn theiholcs, and then be;

conducted upward through the fluef, or they may pass directly upward into thc vertical `luesf, as indicated by4 the arrow at e. In the former caso the vcurrent is controlled bythe damper g, in the latter by 'an annular-ringl damper, which is operatedV by the projecting lever 7L. Air is admitted into tho air-passagejz' from thc lower; i 'i oven a, .and also fror'nabovc the `plate F, as seen at J. Heated 4air may be conducted directly into the upper oven and itis controlled by suitable dampers, so that it may be discharged into tho room, if desired, through i apertures mark ed c.

l"In the bread-oven E there are revolving shelves marked m m, which are supported by pivots n n. These shelves are perforated with holes, and they are connected together byvertical rods, and thereby to a spider, o,

y which is supported by the upper pivotv n.V P is the door, through which theV fueliis introduced into thefurnacen lhe fuel burns only at the base, or on4 the grate, from whence it ascends, as already described. The pot or` i boiler-holes through the top of the stove arev seen in fig. 2, marked S.

What I claim as new, and desire to secure by Letters Patent,` is- 1. The construction of the oven C', formed by theA circular slides a around the furnace,l as herein described,`

for the purpose specified.

2. The stove A, constructed as described, and provided with the air-opeuings e', forming a communication from the oven C', through said furnace, to the annular flucs z' and bread-oven E, as herein described, for the i purpose specified.

3. I claim the ilues ff,'aud the air-passages J z'z', and the revolving shelves m m, in the elevated oven E, i

as `shown and described.

arranged relatively to the fuel-'supply chamber B, and operating substantially HAMILTON, STICKNEY.
