This invention relates generally to the art of making stoves and ranges for culinary purposes, and particularly to a special form of range in which solid or gaseous fuel can be utilized, or the cooking can be done with electricity if desired.

The main object of this invention is to provide a special form of range whereby the apparatus for burning solid fuel is so constructed as to cause approximately complete combustion, with the result of eliminating the soot from the utensils, and naturally from stoves and flues, and also the elimination of smoke from the gases emerging from the chimney.

The second object is to provide a novel form of range in which the oven element can be moved laterally over different portions of the range top for the purpose of utilizing the particular kind of heat desired, and also for the purpose of eliminating the necessity of making right and left hand ranges, and for the further purpose of so constructing a range as to enable its user to adapt the range to any kitchen in which it may be placed.

The third object is to so construct the range that odors from the cooking are drawn into the combustion area or carried off through the smoke flue instead of escaping into the room, as is ordinarily the case where no special means is provided for taking care of same.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawing, in which:

Figure 1 is a front elevation of the range with one half broken away in section along the line 11 in Figure 2. Figure 2 is a vertical section taken along the line 22 in Figure 1. Figure 3 is a horizontal section taken along the line 33 in Figure 1. Figure 4 is a broken horizontal section taken along the line 4% in Figure 1. Figure 5 is a vertical 1 section through the upper portion of the solid fuel section showing a modified form of top for converting same into a heater.

Similar numbers of reference refer to similar parts throughout the several views.

Referring in detail to the drawing, the

range about to be described is mounted on four legs on which is placed a base 11. On the base 11 is placed the body of the range consisting of an outer shell 12 and an inner shell 13 whose lower ends are secured to the base 11 which is provided with openings 14 for the upward passage of air between the members 12 and 13. An ash box 15 is placed on the base 11 within the shell 13, and across one side of the outer shell 12 is placed a front 16 having an ash pit door 17 mounted thereon, which door is provided with a damper 18. A fire door 19 is also provided in the front 16 and has a damper 20.

Behind the fire door 19 is placed the fire box lining 21, under which are the grates 22. A removable front 23 is also provided for use with solid fuel. Over the rear portion of the grate 22 is a bafile plate 24; whose forward edge is preferably curved, as indicated. This plate causes the burning gases to travel forwardly in the combustion chamber before they can escape to the smoke flue 25. V

The range top is divided into three sections 26, 27 and 28, the section 26 having the usual gas burners (not shown), under the control of the valves 29. The section 28 has an electric element 30 of any suitable type. Under each section 26 and 28 is a bottom 31, the inward portion of each of which extends over the space between the shells 12 and 13 and this portion is provided withholes 32 adapted to admit warm air from the sides of the range into the spaces under the top sections 26 and 28. i

The inner side of each member 31 is upturned to form a wall 33 into whose offset 34 are formed the holes 35 through which Warm air from under the tops 26 and 28 can enter the combustion chamber under the section 27, and thereby greatly improve the burning conditions within the combustion chamber. Heated air can also pass from the ash pit through the holes 36 in the lining 21.

At the back of each section 26 and 28 is formed an opening 37 through which some of the gases can escape through the smoke flue 25. The back 38 of section 27 has a smoke outlet opening 38--A formed therein.

Across the sections 26, 27, and 28 are formed the grooves 39 and 40 in which rest the runners 41 of the oven 42 whose rear wall 43 is provided with an outlet damper 44 connecting with the smoke flue 25. Usual shelves 45 and door 46 are also provided for the oven 42. A shelf 47 is supported by the side brackets 48, across which is placed a back 49.

In the form shown in Figure 5 a special top 50 is provided for the solid fuel burning section, and this top is provided with a plurality of holes 51 in the upper side thereof through which heated air can pass from between the shells 12-A and 13A. The usual stove lids 52 are illustrated.

In operation when fuel is burned on the grates 22 air is drawn through the holes 35 and 36 as required by the burning fuel. As combustion continues the shells 12 and 13 become heated and warm the air passing upwardly between same.

It will be observed that since a portion of.

the air for feeding the combustion is drawn from the sections 26 and 28 that any odors from cooking or burned gases which may be under these sections are drawn into the stove and carried out through the smoke stack. Also the upward flow of air between the shells 12 and 13 soon becomes so hot as to form a downward blast of air into the combustion chamber.

Under actual operating conditions this construction has shown itself capable of almost total elimination of smoke and soot.

I am aware that many forms of stoves and ranges have been constructed in the past; I therefore do not claim such devices broadly, but I do intend to cover all such forms and modifications thereof as fall fairly within the appended claims.

Attention is called to my prior application Serial No. 122,618, which became abandoned Aug. 27 1927, of which this application is a re-filing.

I claim:

1. A range consisting of a body having an ash pit formed therein, said body having an air warming compartment therein around said ash pit and fire box, said air warming compartment being open at its upper and lower ends, a cover over said fire box having openings formed therein communicating with the upper end of said air warming compartment, a range top extending beyond each side of said body, said extensions having heating elements therein, each of said extensions communicating with the upper end of said warming compartment having outlet openings for the escape of surplus air and gases, and a smoke pipe on the rear of said range communicating with said fire box and said extension openings.

2. A range having a central body member for solid fuel including an ash pit and a combustion chamber surrounded by an air warming compartment open at its upper and JOHN B. EHRLICH.
