' JAMES GREEK AND RUFUS J (KING, OF DAYTON, OHIO,

Letters Patent No. 103,449, dated May 24, 1870.

COOKING-STOVE.

The Schedule referred to in these Letters Patent and making part of the same.

We, JAMES GREEK and RUFUS J. KING, both of Dayton, Montgomery county, Ohio, have invented a new and useful Improvement in Cook-Stores, of which the following is a specification.

Nature and Objects of the Invention,

. Our invention is designed to enable the heating of the draught-air to a cook-stove, soas toeconomize heat and increase combustion and consistsessentially of the following devices, to wit:- an outer registered plate or shell in front of the fire-front, inclosing a-passage or jacket through which,'-when desired, the

diaught-air passes to a' space between "the inner and Outer fire-doors, and becomes highly heated before entering the'fire-chamber, which it does underneath the inner-fir'e-doors.

Figure 3 is a similar section, with the registers closed.

Figure dis a vertical section at the linear x.

i A represents the fire-chamber of a'cookstove.

B B its front walls.

' Q, its front opening, closed by a pair of imperforatc doors D D, between whose lower edges and the hearthbottom a space, (I, is left for the entrance of the draught- Placed a short distance in front of the walls B B are plates E E, constituting a false front, and forming, with said walls B B and with the inner and outer firedoors, an inclosure or jacket, F 1 which, besides preventing theescape of heat from the fire-chamberint-o the room, serves as a passage in which the draughta-ir becomes preheated on its way to the'fire, so as to f stimulate combustion and to avoid cooling the oven by' the contact of cold air.

The plates E- E have registered openings 0 e, which, when open, permit the entrance of draught-air, and,

: our hands.

when closed, stop the passage of air, and, when the outside doors are also closed, convert the jacket I E into a warm-air chamber, which conserves the heat of thc-fire-chamb'er, and at the same timeprevents a too rapid'consumption of fuel therein.

Outside, and some distance in front of the doors D D, are outer doors G G, which, when closed in front of the doors D D, as in figs.'2 and 3, convert the 'entire front into a draught-passage or warm-air jacket, according to whether the registers are opened or closed.

- When it is not desired to use the passages I, the outer doors G G may be thrown open, so as to permit? the draught-air to 'pass' directly into'the stove. All

of our fire-doors are plain or imperforate.

Although preferring two inner and two outer doors, the former hinged and the latter sliding, as shown, yet it is evident a single inner door or fender and a single outcrdoor or fendermight be employed, and. said doors might beeither slid-able or be hung on hinges, as preferred.

- The draught-passages F F, might, if desired, receive air wholly or partly through apertures in the janibs.

Claims.

To claim as new and of our invention-'P 1. The draught-passage flue or jacket F F, formed by? the'peifoiate and registered plates E E', arranged on the outside of the fire-front of a cook-stove, substantially as and for the purpose set forth.

2. The imperforatc inner fire-front B B and outer perforate and registered plates E E, in the described combination, with the inner and outer sets of imperforate fire-doors I) D and G G', for the purposes set forth.

In testimony of which invention we hereunto set JAMES GREEK. RUFUS J. KING. \Vitnesses a Gno..H. Kmen'r, FRANK L. ALLEN.
