COOKING-STOVE.

Specication of Letters Patent No.

To all whom t may concern.' y

Be it known that I, HosEA H. HUNTLEY, of Cincinnati, Hamilton county, Ohio, have invented new and useful Improvements in Cooking-Stoves; and I do hereby 4declare the following to be a full, clear, and eXact description of the nature, construction, and operation of the same, reference being had to the annexed drawings, which are made part of this specification.

Figure 1, is a vertical section, through the lineA-B (looking outward). Fig. 2, is a transverse section of the stove through the line C D (looking forward). Fig. 3 is a horizontal section through the line E F (looking downward).

The obj ect of this invention is to furnish the oven with front corner diving fiues which receive their heated draft, (a reservoir of heated air being retained in a chamber under the fire Hoor), direct from the re, and also to pass portions of the draft through the oven door, (when the door is closed) andv the bottom flue; the portion passing through the doors being discharged into the back corner diving flues, and the portion passing through the front diving flue being discharged into the bottom oven flue. )When the oven door is open the draft through it is shut oif by a 'gravitating damper, and the entire draft passes to the bottom oven flue down the front and back corners. Closing the door opens the damper and allows part of the draft to pass through it.

(a) is the fire place; (Z2), the boiler flue; (c), the corner back diving flue; (d), the flue under the oven leading to the pipe flue.

(f) is the oven.

(g) is the hot air chamber under the floor of the fire-chamber.

Between the oven (f) and the air chamber (g) there are two diving flues (i), one at each side-of the stove, into which a draft is admitted through openings (7c) direct from the fire, by means of openings Z) in the fire floor; a chamber or cold air flue (h) 8,541, dated November 25, 1851.

is placed between these iiues (i) and as the upper part of this cold air flue occupies the whole breadth of the stove, the cold air is allowed to escape through openings (m) in the side plates of the stove and thus cool the fire back. Openings (n) are made in the side plates when it closes in the flue and a gravitating damper (0) with corresponding openings is hung over these openings (n).V These openings and damper are within the range of the door. The damper has a latch formed projection from it, which passing out is operated by the closing door. The openings spoken of in the side plate and damper are made to correspond with similar openings in that portion of the face of the hollow door which covers them, and thus when the door is closed a hot draft is passed through it and made to discharge by a similar arrangement on the face near its opposite side into the back diving iiue, along with the current in which it is carried under the oven and thence to the escape pipes. The chamber (g) under the fire floor receives from the fire and furnishes an ample supply of hot air tot the flues keeping the front lower corner of the oven in good baking condition.

The red arrows indicate the draft which is divided between the bottom iiue and the oven door, when the latter is closed; the black arrows represent the main draft; and the blue arrows the cold air transit.

Having thus fully, clearly and exactly described and represented my improvements in stoves, what I claim therein as new and desire to secure by Letters Patent, is

The diving fines opening from the floor as described and in combination with this the chamber (g) for the purpose described.

In testimony whereof, I have hereunto set my hand before two subscribing witnesses.
