To all 'whom t may Gomera: A

Be i -lknown that l, Hanni' Wannen, a citizen ofthe llnited States, residing in the invented certain 'new and useful lmproveof which the following is a '.lhis invention relates to stoves and seeks 4to provide a cooking stove which may utilize either. solid or duid fuel and in which the heat from either fuel will be most advan- 4 -teously utilized. An. object of the invention is to provide an Improved circulation of the heat so that it will act upon the bottom of the oven while at its greatest' intensity and before being chilled through a f tortuous circulation. Another object of the invention is to provide ecient ventilation for the oven and afurther object of the invention is to provide novel means whereby the oven may be heated by Huid fuel, and the deposit in the oven of soot and other waste products from the combustion ofsolid fuel will be prevented. @ther objects of the invention wi appear in the ycourse of the following description and the invention consists in certain novel features which will be hereinafter first fully described and then more particularly pointed out in the appended claims.

ln the drawings- Figure 1 is a longitudinal vertical section of a cooking stove having my improvements embodied therein; l Fig. 2 is a transverse section; the section' line 1-1 in this figure indicating the plane upon which the section shown in Fig. 1 is taken;

Fig. 3 is a plan view. The outer walls 1 of the stove may be of any well-known or preferred type ,and to-e gether with the bottom plate 2 are supported upon legs 3 in :the usual manner. 'lhe top plate t of the stove presents an outer substantially rectangular frame with an intermediate transverse connecting bar and is provided around the openings defined by the frame with shoulders or flanges 5 to support the usual utensil-carrying lates. dt one end of the frame, ll provide thegrids 6 of the usual design employed in oil or gas stoves and at the other end of the top frame ll provide the stove plates 7 having o enin formed therein which are adapte to Fd closed by the lids 8 in the usual manner. A. partition 9 depends from the intermediate connecting bar of the top frame and at one end of the me a wall10 depends therefrom and presents a shoulder 11 to partly support the tire-box or basket 12. 'lhe said re-box or basket is provided with the usual grate 13 in its bottom and a receptacle la is disposed within the stove around the said fire-box or basket to receive the ashes 'from the grate. The rear side or wall of this ash receptacle fits against atransverse wall 15 which is disposed in parallel spaced relation to the partition 9 and at its upper end supports one side of the re basket, as clearly shown in F 1g. 1. Upon the said upper end of the wall 15, ll also provide a dedector 1b which rises above the fire basket and terminates short of the top frame of the stove, the ends of the said dedector being in' spaced relation to the front and rear walls of the stove, as will be readily understood on reference to F ig. 3. The said delector prevents the heat rising from the iire'basket 12 passlng directly into the flue 17 defined by the wall 15 and the partition 9 and causes the .said heat to play upon the under side of the plates 7 the lids 8 or upon the bottoms of the cooking utensils whichaare at times substituted for the lids. The partition 9 terminates short of the bottom late 2 of the stove so that a due 18 isA de ned between the bottom plate 2 and the bottom 19 of the oven, the partition 9 having one end wall of' the oven bearing against one face and having a shield 20 of asbestos or similar material upon its other face so that the oven will beprotected from the intense heat of the currents owin from the re basket 12 through the flue 1 'lhe flue 17 will be comparatively short and, consequent ly, the hot currents Howing therethrough will not be lowered perceptibly in temperature before they reach the iiue 18, and in dowin through the latter Hue they will play upon the bottom of the oven so that the oven will be most advantageously heated. The end wall 21 of the oven which is more remote from the partition 9 is spaced from the adjacent end wall of the stove so that a due 22 1s provided rising from the Hue 18 tothe space above the oven and the products of combustion are thereby given a thorou h' llll from thebasket 12 to the opening 23 obtained, I provide an opening or passage through the partition 9 and also provide a damper 24 which is adapted to close said opening.' This damper may be a plate secured to and carried by a rock shaft 25 which is journaled in lugs 26 upon the partition and extends through the front wall of the stove where it is equi ped with a handle 27, as will be readily un erstood. It will be readily noted that the flue 22 leads into a iiue 28 which is defined by the front and back walls of the shell of the stove the top of the oven, and a horizontal partition or shelf 29 arranged above and parallel with the top of the oven, the exit opening 23 being loc-ated in the back wall of the stove adjacent the damper 24 so that before the heated currents are permitted to escape they circulate completely around the oven. In starting the fire, the damper 24 is, of course, moved to open position and the products of combustion flow directly from the fire basket to the exit 23.

The oven is provided with an inner wall 30 on its back and two sides spaced from its outer walls, and the oven door 31, which, in its closed position, constitutes the front wall of the oven, is hollow, as clearly shown in Fig. 2. Openings 32 are formed through the back Wall of the stove and similar openings 33 are formed through the door 31 adjacent the lower hinged edge thereof so as to admit fresh air to the space between the two walls of the oven to min le with the iiames from the burner 34 and t ereb promote combustion of fluid fuel and a so set up a draft or circulation through the oven which will prevent an accumulation of obnoxious fumes or gases therein. The burner 34 is arranged at the, bottom of the oven across the back thereof `and along. the two sides, the innermost end ofthe burner being closed by a cap 35 or other convenient dev1ce. The fluid fuel is admitted to the burner through a branch or supply pipe 36 leading through the side of the stove and equipped with an air mixer 37 in the usual manner. The uid is brought to the said air mixer and supply pipe 36 through a pipe 3-8 leading from the main supply pipe 39 which may be connected in a well-known manner with algas main or an oil reservoir. The main supply pipe 39 is carried across the front of the stove near the. top thereof, as shown at 40, to feed burners 41 disposed between the partition or shelf 29 and the top of the stove, each of said burners being equipped with an air mixerv42 in the usual manner.

The inner wall 30 of the oven is provided with openings 43 therethrough at intervals and over each of said openings is a deflector 44 so that While the heat from the burner 34 may pass into the oven in an upward. direction it will be turned toward the center of the oven and, therefore, most advantageously utilized. Larger openings 45 are provided in the inner wall of the oven adjacent the top thereof so that the excess heat may pass through the openings 46 in the to of the oven and thence enter the flue 28. Iilpon the top of the oven is a slide 47 having openings 48 therein adapted to registery with the openings 46 and over the said slide I provide a hood or cover 49 which extends longitudinally of the flue 28 and abuts the partition 9 but is spaced from the wall 1 so that it offers no obstruction to the circulation through the flue 22 nor to the escape of the gases from the oven into said fiue. This hood, however, does eifectually prevent soot or other products of combustion from the fire basket 12 being deposited upon or in the oven. A link 5() is secured to the slide 47 and extends through the adjacent end wall of the stove and has a pin and slot engagement with the lever 51', as shown at 52, the said lever 51 being connected With the handle 53 of a stop cock 54 in the pipe 38 so that when the stop cock is opened to permit iiuid to flow tothe burner 34 the slide will be moved outwardly and the openings 48 therein caused to register with the openings 46, thereby establish ing communication between the oven and the space below the hood 49. It will further be noted that the lower corners of the inner wall of the oven are disposed diagonally as indicated at 55, and the jet openings 56 of the burner 34 are so disposed that the flame therefrom will play directly upon this inclined or beveled portion of the oven.

Having thus described the invention, what is claimed as new is:

1. In a stove, the combination of an enclosing shell, a vertical transverse partition arranged intermediate the ends of the said shell and terminating short of the bottom thereof, a fire-box disposed within the shell at one side of said partition and spaced from the partition, an oven at the opposite side of the said partition spaced from the bottom and sides of the shell, a horizontal partition leading from the vertical partition to one end of the shell in spaced relation to the top of the oven, the said vertical partition havin an opening therethrough and the she being provided with an exit opening between the top of the oven and the horizontal partition and adjacent the opening in the vertical partition, and a damper arranged to close the opening in the vertlcal partition.
