4 Claims.

This invention relates to a dual or combination range and more particularly to an improved construction of range having two independent heating means which may be used for heating the oven thereof and which may be employed without the use of a bale plate, thus simplifying changing over from one form of heating means to another, and also permitting simultaneous use of both of the forms of heating means.

More particularly, it is an aim of the invention to provide an improved combination range having a compartment containing a re box adapted to be heated by and contain either an oil burner or suitable means for containing a coal fire, the other compartment of the range being provided with an oven having ues extending around the oven and connecting with the re box, and a broiler, disposed beneath the oven and provided with a gas burner and having passages communicating with the oven so that the products of combustion can pass through the oven to permit heating of the oven either by the products of combustion from the lire box or from the gas burner.

Still another aim of the invention is to provide improved damper means for closing or exposing openings to permit the products of combustion from the re box to pass directly from the range, above the oven, or indirectly from the range, below the oven and after having been directed around the oven for heating the same, and for controlling flue openings through which the heated products of combustion from the gas burner, disposed within the broiler, are exhausted from the oven.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, which illustrate a preferred embodiment thereof, and wherein:

Figure I is a view partly in front elevation and partly in section taken substantially along the plane of the line I-I of Figure II,

Figure II is a side elevational view partly in.

vertical section taken substantially along the plane of the line 2--2 of Figure I,

Figure III is a horizontal sectional ,View taken substantially along the plane of the line 3-3 of Figure I,

Figure IV is a fragmentary side elevational View of a portion of one end of the range, and

Figure V is a vertical sectional View taken substantially along the plane of the line V-V of Figure II.

Referring more particularly to the drawings,

wherein like reference characters designate like or corresponding parts throughout the different views, I designates generally the combination or dual range which includes a rear wall 2, top 3 and bottom I and which is provided adjacent its top 3 with a gas burner compartment 5, at one end thereof, having a plurality of gas burners, not shown, controlled by the valves or controls 5. The range I, at the end opposite to the end thereof which is provided with the gas burner compartment 5, is provided with a compartment 6 forming a re box in which may be either mounted an -oil burner, not shown, or grates, not shown, for a coal re.

Beneath the gas burner compartment 5, the range I is provided with a steel oven I having side walls I2 and III, and a top Wall I3. The fire box 6 is separated from the space containing the oven 'I by means of the inner side wall I5 of the fire box 6 which is spaced from the adjacent wall I2 of the oven 'I and which terminates at its top at substantially the level of the top wall I3 of the oven 'I to provide a space I5 between the upper edge of the wall I5 and the top 3 of the range I, for a purpose which will hereinafter be described. The wall I5 and the wall I2 combine to form a diving ue 8. The gas burner compartment 5 is provided with a bottom wall I6 which combines with the top I3 to form a space 9 above the oven I. The range I is provided with an end wall 3G, disposed adjacent the oven 'I and with an inner wall I'I, arranged between the wall 30 and the oven wall I4, which combines with said wall I4 to form a diving flue I5, which is disposed on the side of the oven 'I opposite to the flue 8. The front wall 2 of the range I and its rear wall 2, also form the front and rear walls, respectively, of the oven 'I.

The range I is provided with a broiler 26, disposed beneath the oven 1, the rear and front walls of which are formed by the walls 2 and 2', respectively. Broiler 26 is provided with side walls 25 and a top wall formed by the horizontal, sub-bottom 20 of the range I which forms a support for the walls I5 and II. A portion of the sub-,bottom 2D is disposed beneath and spaced from the bottom of the oven 'I to form therebetween a space forming the bottom ilue I I which communicates with the lower ends of the diving ilues 8 and IIJ. The bottom of the oven 'I is formed by a pair of sections I8 which combine to form a central clean out opening I9 which is provided with a downwardly offset inwardly projecting flange I9 forming a seat for supporting a clean out plate to removably mount it thereon for closing the opening I9 and which when in place forms the central portion of the bottom of the oven 1.

The sections I8 are each provided with a plurality of ports or openings 22 which are surrounded by annular anges 21 which depend from the sections I8 for receiving the upper, restricted ends of conical tubes or passages 2|, which are formed integral with the sub-bottom 28 and which open at their lower ends into the broiler 26. The spaces between the upper, open free ends of the tubes 2| and the anges 21. are closed and sealed by means of stove putty, as indicated by the reference numeral 53. The sub-bottom 23 is also provided with a conical shaped upset recessed portion 23 which is centrally disposed beneath the oven 1 and which terminates just beneath the plate 45.

A gas burner 24, for supplying heat to the broiler 26, is disposed therein beneath and adjacent to the sub-bottom 20. The burner 24 extends through the rear wall 2 and is supported at one end thereby and is supported at its opposite, forward end by means of a bracket 46 which is 'attached to and depends from the sub-bottom 28.

The range is provided with a smoke box 3| attached to and disposed on the outer side of the rear wall 2 behind, above and below the oven 1 and which includes a rear wall 28 which is spaced from the wall 2. Wall 2 is provided with an opening 29 connecting the smoke box 3| to the flue 9, an opening 36 connecting the smoke box 3| and flue and two spaced openings 29 connecting the smoke box and the oven 1. A pair of shields II' is disposed between the bottom sections I8 and the sub-bottom 20, said shields extending from the rear wall 2 forwardly of the flue and terminating in spaced apart relationship to the front wall 2'. The shields II' converge toward their forward, free ends with the opening 36 between the remote, rear ends of the shields for a purpose which will hereinafter ecome apparent.

A bar 38, as best seen in Figure V, is mounted on the outer side of the wall 2 and within the smoke box 3| and is connected at its lower end with a damper plate 31 and at its upper end with a damper plate 41. Guide members 43 are secured to the outer side of the wall 2 and arranged in pairs for engaging the ends of the plate 31 and the outer edges of extensions 48 for slidably mounting the bar 38 and plates 31 and 41 for perpendicular movement relatively to the range I. The upper plate 41 is provided adjacent its ends, with the downwardly and outwardly curved extensions 48 for closing the flue openings 29. When the plates 31 and 41 are in a raised position, as seen in Figure II, the plate 41 closes the opening 29 and the extensions 48 close the openings 29. When the plates 31 and 41 are moved downwardly to a lowered position, the plate 31 closes the opening 36, which was exposed when said plate was raised, and the plate 41 and its extensions 48 assume a position for exposing the openings 29 and 29'.

A rod or shaft 42 is journaled in the side walls 49 and 5E) of the smoke box 3| and has. one end thereof, not shown, extending through and journaled in an indicating plate 5|, seen in Figure IV, which end is provided with a handle or knob 52 which is keyed thereto for turning the shaft 42. An arm or lever 4| is keyed to and projects from the shaft 42, within the smoke box 3| and is provided with a roller 39 at its free end which is rotatably mounted thereon and which is adapted to engage under a shoulder or extension 40 which is likewise disposed within the smoke box 3| and which projects from the plate 41. The indicator plate 5| is provided with -an arrow pointing toward the handle 52 and designated by the word Oil and with a second arrow, spaced from the aforementioned arrow and likewise pointing toward the handle 52 and which is designated by the word Gas." Between the aforementioned arrows, the word Bake is inscribed on the plate 5|.

The front wall 2' of the range is provided with an opening 32 communicating with the oven 1 and which is adapted to be closed by a door 33 which is vertically hinged by means of the hinges 55. An opening 35 is also formed in the wall 2' and which communicates with the broiler 26 and which is adapted to be closed by means of a door 34 which is horizontally hinged at its bottom by means of the hinges 56. The side walls of Vthe oven and broiler are provided with the inwardly projecting guides 44 for removably and slidably mounting oven and broiler racks, not shown.

The range is supported by depending legs 54. The burner 24 is provided with a valve operator or knob 5" disposed at the front of the compartment 5 and adjacent to the operators 5.

Assuming that there is a iire within the lire box 6, produced by either a coal fire therein or by an oil burner, and assuming that it is desired to heat the oven 1 by means of the heat from the nre box 6, the handle 52 is turned to the position, as seen in Figure IV, so that it will be pointing toward the arrow marked Oil and so that the arm 4| will be disposed in the position, as seen in Figure II, to cause the damper 38 to be held in a raised position to expose the opening 36 and to close the openings 29 and 29. The heated products of combustion, as indicated by the arrows 51, as seen in Figures I and III, will pass from the re box 6 through the passage I5' where they will divide with a portion thereof passing downwardly through the flue 8 and the remainder thereof passing horizontally through the iiue 9 and then downwardly through the ue I8. The products of combustion will enter the flue from the lower ends of the flues 8 and I0 and will be directed by the deflector shields toward the front of the range I to heat the bottom of the oven 1, tubes 2| and the upset vrecessed portion 23. The heated products of combustion will Vilow around the forward, free ends of the shields as illustrated in Figure III, and rearwardly therebetween and through the opening 36 into the smoke box 3| from whence they will be exhausted through a smoke stack, not shown. It will thus be obvious that the top, bottom and sides of the oven 1 will be heated exteriorly by the heated products of combustion from the fire box 6 for heating the interior of the oven and that the products of combustion will be directed around the oven by a circuitous route to obtain the maximum of heat radiation therefrom to the interior of the oven. At the same time, the oven 1 is effectively sealed from the ues 8, 9, and so that none of the products of combustion from the fire box 6 will enter the interior of the oven 1.

In order to bake more rapidly in the oven 1 or for the purpose of broiling, the burner 24 may be lighted and the flame controlled by the knob 5" and the handle 52 is then turned in a clockwise direction, as seen in Figure IV, so that it will point toward the arrow marked Gas This will cause the shaft 42 and the lever 4l to be turned in a clockwise direction or in a counterclockwise direction, as seen in Figure II, to swing the lever 4I inwardly and downwardly of the range I to permit the damper 38 to slide downwardly so that the plate 31 will close the opening 36 and the plate 41 and extensions 48 will be moved to positions for exposing the openings 29 and 29. The heated products of combustion from the burner 24 will heat the recess 23, disposed thereabove for heating the lower portion of the center of the oven 'I and the products of combustion will also pass upwardly through the tubes 2l and through the oven 'l from where they will pass through flue openings 29 to the smoke box 3l for supplying heat to both the broiler and oven. The oven 1 may thus be heated by the burner 24 and the coal re or oil burner in the iire box 6 extinguished or if there is a re in the re box 6 the heated products of combustion therefrom will pass from the passage l directly into the passage 9 and through the opening 29 into the smoke box 3i for heating the top of the oven l' to further assist the heating of the interior thereof. It will be obvious that the range l provides an oven 'l having greater area that can be used for baking, due to the fact that there are no burners disposed therein making the space saved thereby available to be occupied by the articles to be baked.

Various modifications and changes are contemplated and may obviously be resorted to as only a preferred embodiment of the invention has been disclosed.
