SELF-FEEDING WOOD AND COAL COOKING-STOVE.

.ll'he Schedule referred to in these Letters Patent'and making part of the same To all whom it may concern Be it knownthat I, JOSEPH F. Pom), of Cleveland, in the county of Guyahoga, and State of Ohio, have invented certain new and useful Improvements in Self- Feeding Wood and Coal Cooking-Stoves; and the following is a full, clear, and exact description of the same, reference .being had to the accompanying drawings, making a part of 'this specification, in which- Figure 1, Plate 1, represents a perspective view and design of my improved stove complete. I Figure 2 shows a side view, in a vertical section, through the interior of the stove.

Figure 3 is a front view or transverse section of the same. p

Figure 4, Plate II, represents an interior plan or top view of the adjustableheat-controller, and aplan view of the upper portion of the fire-pot, rate, and dampers.

Figure 5 shows the bottom plate, with the openings for inserting and securing the legs to the stove; also, a sectional top view of the flue-plates under the oven for controlling the heat.

Figure 6 is an under-side view of the top or griddleplate, showing the sliding dampers.

Figure 7 represents, in perspective, a view of the feeding-door, with a coal-shute attached, and the doorframe on which the door is hung to operate.

Figure 8 showsa view of a stove-leg, with my improved construction and mode of fastening to the bottom of the stove.

The object of my invention is to economize heat-,1

time, labor, andro'om, in a base-burning cook-stove; and

It consists- First, in a chute constructed in a'semicircularform, attached to the feeding-door, to which is connected it semicircular sliding valve or shutter, to close the magazine or fircla-eceiver, the same being operated by the opening and closing of the door.

Second, in the series of sliding valves attached to the under side of the top or griddle-plate, operating to and from the fuel-magazine,'to control the heat to each of the griddles or holespaces, separately. 7

Third, in the construction of the midi-iii or secondmy top plate, with its supporting-partitions, which divide and separate the series ofgriddle-holes, so that the heat may all be directed to any one of them, by

the controlling slide-valves or dampers;- also, in the movable plates attached to the secondary top, for closing up a portion of the openings under the front holes.

Fourth, the curviform fire-pot, which forms the inner case and top of the oven, with its fines or open.- ings at the outer edge, to allow the products of combustionto pass down the sides and underneath the oven, the closing side valves with their jointed handles, 85c.

Fifth, my invention further consists in forming a metal rim, with a series of fingers projecting upward from the rim, to come near or rest against the lower portion of the fire-pot, to stir up and liberate the ashes from the sides;

Sixth, in the adjustable moving plate or false bottom, to regulate the width of the space for the heat under the bottom of the stove-oven, the same to be operated by thumb-screws, or equivalent devices.

Seventh, also, in the-division-plates between the base and the oven-bottom, so that-the heat may he directed through the side fines and openings under either the front or rear portion of one or both of the ovens.

Eighth, in the construction and mode of forming the fastenings for the stove'legs or feet, and the oblong openingsin the bottom or base-plate, to admit and secure the same. 4

To enable others to make and use my improvements in stoves, I will describe them more fully, referring to the drawings, and to the letters of reference marked thereon.

I make my improved self-feeding base-burnin g cookstoves cylindrical in form, of any suitable or required slze.

The base or bottom plate A is supported on legs a a a, or feet, to elevate it to a convenient height for use.

The plate B, which forms the bottom of theoven c c, has a recess, D, in front, and is elevated above the base-plate a sufficient distance to leave a space, E, for the fines F .F and heat to circulate freely under the ovens.

In the space E is fitted a movable plate or false bot,- tom, 11 b, which is supported on thumb-screws c 0, so that the height of it may be adjusted in the space to bring the heated air or combustion closer to the bottom underneath.

flhere are also partitions (I (Z in the space E, so that by means of the dampers in the tines K K, the heat may be avoided or shut off, in a greater or lesser degree, from either the front or rear portions ofthe ovens O O, which surround the fire-pot G, all except about one-fourth of its diameter in front.

In this recess D the air is admitted under the grate g, and the opening to the ash-pit h is closed by astopper, e.

The front oven-doors I I are hinged at the outer corners of thetwo sides of the recess ll, so that they close inward and latch nearthe fire-pot G, which forms the inside and top of the ovens C O.

The outside plate. J J, being-of sheet-metal, surrounds the fire-pot, except the front recess,

a space for the fines F F to conduct the flame and heat under the oven, when desired.

The outside or body of the stove H H may be made leaving f sheet or cast-metal, and with openings in the rear, on either side of the smoke or draught-pipe I, to be closed with sliding or hinged doors.

The circular rim ,4 is made with a series of long fingers 'i 'i, i i, projectingnp from the rim g, which come in close proximity to the sides of the fire-pot, and effectually stir up and liberate the ashes when the grate. ,is shaken.

On the outer edge of the tire-box G, are openings K K to the fines F 1 which are provided with sliding dampers 7. 7;, which have jointed handles 1 l to fall down when the dampers are closed, and hold them firmly in their places and out of the way.

A little distance above the top of the curviform fire-pot and the dampers 7.11:, is placed and secured the diaphragm or secondary top plate L, which is provided with rib partitions m m m to come between each .of the kettle or griddle-holes o o 0 o in the top plate M.

The open spaces N N N in the diaphragm, coming directly under the griddle-holes, are provided with slides a a, placed in such a position that they can be brought out and close part of thevopenings, so that they will direct the current of flame or heat, or concentrate them more underthe boileror anything placed in the opening.

The smoke or draught-pipe P is placed in the rear,-

opposite the recess 1) in front, and connects at the bottom with the flue Q underneath, so that all the draught may be directed under the oven.

The pipe P is also provided with an opening, 1), and

a closing-valve, q, above the top edge of the fire-pot G, so that the draught is direct from the grate to the pipe which conveys oii' the smoke and gas In the central portion of the stove, on the top M, tbereis placed a turret or dome, It, of any desired size or height, in the front of which is the feed-door S, which isprovided with a curved inclinedchute, T, to convey the coal put into it into the magazine U, in the centre, which supplies the grate and tire-pot.

Over the top of the magazine U there is titted a curvilinear shutter, a", which is connected by a link with the chute T, so that it is opened and closed by the opening and shutting of the feed-door S.

On the under side of the top plate M, in the several compartments N N N N, between the secondary plate L, which forms a separate flue for each of the griddle-holes 0 o 0, there are sliding valves u at or dampers to close up the apertures to the dome, so that no draught or heat will be conveyed into it; or by opening one of the slides u, and closing all of the other fines, the draught and heat can all be brought to bear on one boiler. Y

The communication from the fire to the smoke-pipe P, is allthrough the domeR and openingVinto the pipe at the top, which is curved, and brought forward a sufficient distance to come in contact with it.

In the lower edge of the fire-pot a, in front, is. an opening, S, which extends down to the grate, which is provided with a shutter, T, that may be opened to remove any obstruction from the grate without having to lower the grate g. This is very convenient for those inexperienced in operating grates in stoves. \Vit-h this device, the grate need not be made to lower, to remove anything from it; and again, should the fire and coal fall down while removing the clinkers or worthless substances from the grate, the grate is in its place to receive them, and thereby prevent that which is so much feared'and dreaded,'the falling of the fire and coal when the grate is down, and getting the grate into its-place agahr.

The shutter T may be made of one or more pieces,

' and be hinged to the fire-pot, or move ,in a groove.

The opening S may be closed with a sliding shutter, t.

.in it, in-which to insert the bolt 0.

into the flueQ underneath, to'prevent the dust from .coming out into the room.

In the body of the stove II, between the fire-pot G and the top plate M, I place mica windows y y, to

let the light from the burning fuel radiate into the room.

The windows y y may be placed in sliding or hinged doors Z Z, so that, if desirable, they may be opened to let in air above the fire, and check or stop the draught through the grate g, was to regulate and control the combustion in the fire-pot.

My new and improved method of constructing the fastenings ot' the legs a a. for stoves,is to have a stem or bolt, 0', with an elongated head at right angle with the stem, and parallel with-the top or flat part of the leg, on which the base A rests.

The. base or bottom A has oblong openings 1) b",-cast By their turning the leg one-fourth round, so as to bring the head or bar across the opening, it is securely held-in its place, and should the leg get turned round, to match the opening in the bottom, itcanuot come out unless the stove is raised up bodily. v

\Vhat I claim as my invention, anddesire to se'-' cure by Letters Patent, is-

1. Achnte constructed in asernieironlar form, attached to the feeding-door; also, a semicircular sliding valve, to close the tuel-receiver, the same being operated by the opening and closing of the door, or by arod at tached to the semicircular sliding valve. H

2. A SQI'ltS of sliding valves, tom, attached to the under side of the top M, operating to and from the fuel-magazine It, to control the heat to each of the compartments separately.

3. The plate L, with its supporting-partitious anm m, to separate the series of griddle-holes, so that the heat may be directed to any one of them.

4. The movable plates n n, attached to the diaphragm-plate L, for closing up a portion of the openings N under the cooking-places, as described.

5. The extended fire-pot or top oven-plate G, with openings 70 k at the outeredge, to admit flame and heat down the sides and under the baking-oven, and the corresponding openings F F inthe outer edge of the oven-bottom B, to convey heat to any part of the oven of. circular or oval base-burning cooking-stoves.

6. Jointed rods or handles, for operating dampers in stoves, substantially as herein described.

7. In a circular or oval metal tube, or fire-pot, for base-burning stoves, the opening Sin the lower edge of the fire-pot (4, extending down to the-grate g, and the shutter T to close the same", as and for the purposes hercin described.

8. An adjustable moving plate or false bottom I) b, to regulate the space E for the heat under the bottom of stove-ovens, the same to be operated by thumbscrews or equivalent devices.

9. The division-plates d cl, between the base A and the oven-bottom B, to convey the heat to the front or rear portion of the ovens.

10. The construction and mode of forming the fast- -'enings-for stove-legs, and the oblong openings in the base or bottom-plate of stoves, to insert and secure the same.
