T all wwnt t 77H01/ concern.'

Be it known that I, ROBERT MCD. SMITH, of the city of Louisiana, Pike county, State of Missouri, have invented certain new and useful Improvements in Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to stoves; and it consists in the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Figure 1 is a side elevation of my improved cook-stove. Fig. 2 is a horizontal sectional view on the line' 2 2 of Fig. 1. Fig. 3 is a vertical sectional View longitudinally of the stove. Fig. 4 is a detail view of one of the joints which supports the reservoir of my irnproved stove. Figs. 5 and 6 show details of dampers of which I make use in controlling the circulation of air to the oven.

In the construction of my improved stove the front wall and the rear wall11 are connected by the base 12 and the side walls 13 and 14. The rectangular box thus formed is closed by the top 15. An intermediate wall 16 is fastened to the base and to the side walls 13 and 14 and in a position parallel with the front and rear walls 10 and 11.

In the upper part of the space between the front wall 10 and the intermediate wall 16 are horizontally-positioned grates 17, supported by the angle-bar 18, attached to the inner face of the front wall 10 and the end of the bar 19, attached to the front face of the intermediate wall16, thus forming the iireplace above said grates. The fireback 2O rests upon the rear ends of the grates 17 and against the upper end of the intermediate wall 16. Below the re-grates 17 is the ash-pit, access to which is obtained through the door 21 in the side piece 13.

Formed in the side wall 13 immediately above the ash-door 21 are draft-openings closed by the sliding plate 22. Immediately above the plate 22 is the door 23, communieating with the space immediately below the iire-grates 17. Immediately above the door 23 is the door 24, communicating with the iireplace.

A sheet 25 is horizontally positioned in the space between the wall16 and the rear wall 11 and near the bottom thereof, said sheet being attached to said walls. A smoke and heat deflector 26 extends from the side wall 14 .transversely about two-thirds the distance across said sheet 25 and is attached to said sheet. The space below the sheet 25 is designed to be used as a warming-oven, and access theretois had through the door 27 in the wall 13. A door 2S communicates with the space immediately above the sheet 25 and upon both sides of the deiiector 26,and through said door the ashes and soot may be removed from said space. A sheet 29 is horizontally positioned above the sheet 25,with its center resting upon the upper edge of the detlector 26. The front end of the sheet 29 is attached to the intermediate wall 16, and the sides of said sheet are attached to the walls 13 and 14.

vA sheet 30 is placed in a position parallel with the wall 1l,with its lower end attached to the rear end of the sheet 29 and its sides attached to the side walls 13 and 14. A sheet 31 is horizontally positioned below the top 15,with its front end attached to the top end of the intermediate wall 16 and its rear end attached to the upper end of the sheet 30.

The smoke and heat from the fireplace upon the grates 17 pass rearwardly between the sheet 31 and the top 15, thence downwardly between the sheet 30 and the wall 11, thence forwardly between the sheet 25 and the sheet 29 and against the rear side of the deiiector 26, thence around the free end of said de- .iiector and toward the door 28, thence to the opposite side of the stove through the wall14 and into the base 32 of the stovepipe, which base is attached to the outside of the wall14 and near the bottom thereof.

Aiperforated sheet 33 is placed in a vertical position parallel with and near to the intermediate wall 16, with its lower edge attached to the upper side of the sheet 29 and with its sides attached to the walls 13 and 14. A perforated sheet 34 is placed in a vertical position parallel with the sheet 33 and near the sheet 30, with its lower end attached to the upper side of the sheet 29 and its sides attached to the walls 13 and 14. A perforated sheet 35 is placed in a horizontal position parallel with the sheet 31 anda short distance below said sheet and with its front edge attached to the upper edge of the sheet 33 and ICO its rear edge att-ached to the upper edge of the sheet 34, while its sides are attached to the walls 1 3 and 14. Apertures 36 are formed in the wall 13 and communicate with the space between the intermediate wall 16 and the sheet 33 and immediately above t-he sheet 29. Similar apertures 37 are formed in the wall 13 and communicate with the space between the sheets 30 and 34 and immediately above the sheet 29.

Dampers 38 (shown in detail in Figs. 5 and 6) are operated to regulate the passage of air through the openings 36 and 37. The dampers 3S consist of a bar 39, pivotally connected to the side piece 13 by means of a screw 40.

Disks 41 and 42 are attached to the ends of the bars 39, and flanges 43 and 44 project out wardly from said disks and are designed to be used as handles for operating said dampers. The disks 41 and 42 are designed to operate over the apertures by sliding contact with the outer face of the wall 13, and the passage of air through said apertures is controlled by adjusting the position of said disks by manually engaging the flanges 43 and 44.

The space above the sheet 29 and surrounded by the perforated sheets 33, 34, and 35 constitutes the baking-oven of the stove, and access is had thereto by .means of the door 45 in the side piece 13.

In the operation of the baking-oven air is admitted through the openings 36 and 37 to the space outside of the wall of the perforated sheets 33, 34, and 35 and is highly heated in said space, and said heated air passes through the perforations in said sheets to the interior of the oven.

The object of the perforated sheet is to distribute the heated air as equally as possible to all parts of the oven.

A pair of brackets 46 are attached to the front outer face of the front wall 10 and to the lower part of said wall. Lugs 47 and 48 project sidewise from the free ends of said brackets, and bearings are formed through the free ends of said brackets and in a vertical line between said lugs. Ears 49 are pivotally attached to the free ends of the brackets 46 by means of the bolts 50,passing through said ears and through the bearings in said brackets.

Segmental straps 51 are attached at the centers of their convex sides to the ears 49. I employ two of the brackets 46 in horizontal alinement with each other, and each of the brackets carries one strap 51, which straps are also in horizontal alinement with each other.

The cylindrical reservoir52 is placed in the concaved sides of the straps 51 and securely attached thereto, and thus is formed a pivotal support for the reservoir. The lugs 47 and 4S, engaging the sides of the ears 49, act as stops to limit the motion of said reservoir. A plate 53 is fixed in the wall 10 and directly in front of the fireplace. The inner face of the plate 53 fits closely against the wall 10,

while its outer face 54 is concaved and designed to lit against the side of the reservoir 52. In the upper side of the reservoir 52 is a flaring opening 55, through which water may be inserted into said reservoir.

WVhen the side of the reservoir 52 rests against the concave 53, the heat of said concave, which is derived from the fireplace, will be communicated to said reservoir. -XVhen the water in the reservoir becomes suiciently heated, said reservoir may be tipped away from said concave, thus allowing a current of air to pass upwardly between the reservoir and the concave, and the temperature of the reservoir will not be further increased.

In the top piece 15 are openings in which the stove-lids 57, 5S, and 59 operate.

In the practical opera-tion of the construction described with reference to the oven the air is thoroughly and evenly heated before entering the inner space of the oven, and after being thus thoroughly heated is admitted to the inner space of the oven through the perforatious in the sheets 33, 34, and 35,

thus giving the oven an even temperature in all its parts and making it possible to bake whatever is placed in the oven evenly upon all sides. The air-space between the intermediate wall 16 and the perforated sheet 33 is heated directly from the grates and fireback, and the products of combustion pass entirely around the other three sides of the air-space, thus practically heating all parts of the air-space outside of the perforated sheets 33, 34, and 35 alike, and the air thus heated is distributed to the oven, as heretofore described.

Stoves and ranges may be constructed upon the principles herein disclosed in any size and shape or of any desired material without departing from the spirit of my invention.
