.To @ZZ whmn it rnc/y concern:

Be it known that I, WILLIAM A. GREENE, `a citizen of the United States, residing at Ocean Grove, in the county of Monmouth and State of New Jersey, have in vented certain new and useful Improvements in GookingStoves; 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 it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in cool; stoves and ranges; and it consists in the construction and combination of parts hereinafter set forth, and pointed out in the claims, the .prime object of the invention being to provide a stove possessing great heating capacity with the expenditure of a minimum amount of fuel.

The accompanying drawings illustrate what I consider the best means tor carrying my invention. into practice.

Figure I is a plan view of the stove. Fig. II is a plan view of the same with the top rmoved. Fig. III is a section of Eig. I on line 0c a, taken zigzag to show the connection ofthe flue. Fig. IV is a side elevation of the stove. Fig. V is an inverted View of the center top piece. Fig. VI is an enlarged section on line y y of Fig. V. Fig. VII is an interior elevation of the rear oven-wall. 'Fig VIII is a section on line y y', Fig. VII.

Similar letters of reference indicate corresponding parts in all the iigures where they occur.

The stove-shell is marked a, the oven b, the fire-box c, and the ash-pit d.

In the ash-pit d an ash-pan E is provided, into which the ashes and cinders from firebox c may drop.

The fire-box c is perforated all around and is surrounded by an air-chamber h, the spa-ee between. the fire-box and the rear wall of the said air-ehamber being closed at the bottom, as shown at 7L', so that all air entering through the ash-pit will be compelled to pass into the lire-box. The top of the air-space IlzI is closed all around also, as shown, by plate c', and the only opening to flue e above top of oven is through the re-boX or through certain diffusion-chambers, presently to be described. A passage m connects to the rearo'f the ire-box and leads up and discharges into channels or diffusion-passages n, which are provided on the under side of center plate o of the stovelid. These passages n are inclosed by solid side walls p p and perforate under wall o', a space o2 being left in the center of the plate o, in to which the top of passage lmy projects to deliver the heat, dto., to the diffusion-chambers ln. The rear wall of the passage m may be provided with openings q, which establish communication between the oven and the said passage, and the plates m', extending from each side of the passage to the side walls of the stove, may also be perforated for the same purpose, whereby the oven is thoroughly ventilated. The oven is also provided with openings 7', which permit fresh outside air to enter it, thus su pplying to the articles bein gcoolzed an abundance of pure air. On thc front of the passage fm, is provided a hook or projection 'm2, and at the front of the stove is a narrow longitudinal door m3, which can be raised and a boiler inserted and rested upon hook m2 to bring the body of the boiler just over the top of the lire-box. Air-openings k may be provided in the end wall of the stove to supply additional air to the air-space 7L.

The flue at the back of the oven is provided with a partition ai", which extends down nnder the oven and divides the ilue into two parts,a damperf being provided to close the entrance to one of the said parts. The rear oven-wall s is provided at bottom with enlargements t t, which aiord recesses on the inside of the oven to receive the sides of pans, dac., whereby the capacity of the oven is increased, and the enlargements forming on the outer rear wall of the oven projections t t', which extend into the tine at the rear of the stove and slightly retard the flow of heat, and thus IOC) top and also at the bottom on the rear side and having a passage lead-ing from it up to the top of the stove, and diffusion-chambers formed on the under side of the top communicating with the passage, as set forth.

2. In a eooking-stove, the combination of a fire-box and air-space surrounding the firehox and closed at the top thereof, and a passage leading from the air-space to {infusion-chambers on the under side of the stove-lid, said passage having openings Comm unicating with the oven, as set forth.

In a cooking-stove7 an extension formed on the back of and above the fire-box, having the hook or projection m2, asset forth.

4. In a cook-stove, the combination of the fire-box, the passage m' above and hack of it, a hook or projection m2 on the front of said passage, and a door m3 at the top of the front thereof, as set forth.
