11 Claims.

This invention relates to heating appliances and particularly to a combination fuel and electric cooking and heating range, and it has for an object to provide an improved device of the character set forth.

Combination fuel and electric ranges are old and well known and are particularly adapted for use in kitchens where the only means for heating the kitchen is the range itself. It has not been practical to heat a room with an electric ran e, and, therefore, the combination with an electric cooking range of a coal or wood-burnin: unit for heating a room is desirable.

The coal or wood-burning units of such combination ranges are usually made of heavy steel or cast iron and provided with a lining of fire brick, with the result that they are extremely heavy. The unit is usually mounted at one end of the range and consequently this end of the range is much heavier than the other end so that the range is difficult and awkward to handle both in shipping and installing the same.

Further, present range bodies are made of relatively light-weight sheet metal provided with an exterior surface of vitreous enamel or other covering to provide a pleasing appearance. These light-weight bodies are not particularly suitable to have a heavy fuel-burning unit mounted therein while the range is being handled in shipping, since the sheet metal body may tend to twist and cause cracking of the enamel surface.

It is apparent, therefore, that there is a definite need for a combination fuel and electric range construction in which the fuel-burning unit may be readily placed in the range body at the time the range is being installed in the kitchen.

It is accordingly a further object of the invention to provide a combination fuel and electric range which the heavy fuel-burning unit may be assembled in the range body in the field.

It is a further object of the invention to provide a combination fuel and electric range in which the range body, including the electric portion thereof, may be made as a unit and the fuelburning unit assembled as a second separate unit, but which may be easily installed in the range body without the necessity of dismantling the range body.

These and other objects are effected by the invention as will be apparent from the following description and claims taken in connection with the accompanying drawings, forming a part of this application, in which:

Fig. l is a perspective View of a combination fuel and electric range made in accordance with the present invention, the door which normally conceals the fuel burner being shown open;

Fig. 2 is a plan view of the range shown in Fig. 1, with the fuel burner unit omitted and a portion of the range platform broken away to expose the interior of the fuel burner compartment;

Fig- 3 is an exploded view of the parts forming the range body;

Fig. 4 is a vertical section taken substantially on the line IV-IV of Fig. 2 and illustrating the manner in which the fuel burner unit is installed in the range body, the fuel burner unit being shown in full lines as it appears during an initial stage of the assembly thereof in the range body and being shown in dot and dash lines just prior to its final mounting within the range body Fig. 5 is a vertical section taken substantially on the line V-V of Fig. 2, showning the fuel burner unit in final assembled position in the ran e ody;

Fig. 6 is a fragmentary detail view looking from the left of Fig. .5;

Fig. 7 is :a view corresponding to Fig. :5 and illustrating a slightly modified form of the invention and,

Fig. 8 is a fragmentary detail view looking from the left of Fig. 7.

Referring to the drawings and particularly to Fig. .1, the range, generally indicated it, comprises a base H on which is supported a range body, including an electric cooking range section l3 and a one-piece platform and backsplasher M. The platform l4 carries a plurality of electric surface units It which may be of known construction. The electric range section is provided with an electrically-heated oven (not shown) accessible through a door l1. Switch knobs l8, mounted on the front of the electric range section, control the energization of the surface units 15 and of the oven heating elements, as it well understood in the art. The portion of the range body to the left of the electric range section 16 provides a compartment l9 in which a coal or wood-burning unit 2! is mounted.

Referring now to Fig. 3, it will be noted that the base H is rectangular in outline and made of channel-shaped members and provided with a cross brace 22 which may also comprise a channel member. The electric range section [3 is of known construction and may be fabricated for u e solely as an electric ran e, if desired. In this case, a platform coextensive with the t p of the electric range section and a suitable base would be provided therefor. The electric range 3 section is adapted for use in the present combination of a fuel and electric range, so that the final appearance of the range does not indicate that the electric range section is of separate manufacture, the combination range instead presenting a unitary appearance.

The electric range section 13 comprises a one piece sheet metal wrapper sheet, enameled on its inner and outer surfaces and including

side walls

24 and 25 which are continuous with a front wall 26. This wrapper sheet is flanged at the top and bottom, the bottom flanges being secured to the base H while the top thereof is closed by the top or platform l4. The cross brace 22 and the end member 23 of the base I! are disposed below and are secured to the bottom flanges of the

side walls

24 and 25 of the electric range section.

A transverse sheet metal partition 21 disposed in spaced relation below the top flanges of the range wrapper sheet, together with the platform l4, provides a heater box or compartment into which the surface units l depends. The construction of the electrically-heated oven may be conventional, and it is, therefore, unnecessary to illustrate the same.

Extending upwardly from the left end of the base H is a sheet member 28 which forms the left lateral side wall of the range body. This sheet member is flanged at all of its edges, the lower flange thereof being secured to the upper horizontal flange 28 of the base II. The upper end of the side wall 28 is connected to the electric range section 13 by means of an H-shaped structure 3| made of channel-shaped metal strips.

The longitudinal strips 32 of this structure are secured to the electric range. section I3 along the front and rear edges thereof, while the transverse strip 33 overlies and is secured to the top flange of the side wall 24 of the range wrapper sheet.

As shown particularly in Fig. 3, the platform and backsplasher i4 is preferably formed of one piece of sheet metal having suitable openings 34 therein to receive the surface units l5 and is also provided with a rectangular opening 35 in which the top of the fuel-burning unit 2| is received.

The side wall 24 of the electric range section I 3 and the side wall member 28 define the lateral sides of the compartment [9, which receives the fuel burner 2!, while the platform [4 closes the top thereof. The front of the compartment is closed by a door (Fig. 1), the rear of the compartment being left open, if desired.

The side wall 24 has secured thereto a vertically-extending brace 35 made of angle iron which is spaced from the front wall 26 of the wrapper sheet. As shown in Fig. 3, the side wall member 28 is bent along its vertical front edge to provide a front wall portion 31 and a rearwardly-extending flange 38 from which there extends a flange 38. A channel-shaped brace 4| is secured to the flange 39 with its rear flange 42 disposed in the same vertical plane as the flange 43 of the brace 36. As will appear later, the

flanges

42 and 43 of the braces 4 l and 36 serve as abutments to which the front of the fuel burner unit 2! is secured.

A pair of track-forming members, generally indicated 44 and 45, are mounted within the fuel burner compartment l9 and serve to guide the tively, and at their lower rear ends to the rear channel member of the base ll, as shown particularly in Fig. 4. The horizontal portions 48 of these L-shaped angle irons serve as the guide rails or tracks for guiding the fuel burner 2| into the compartment {9 and for supporting the same therein. If desired, diagonal brace members 48 may extend between and be secured to the ends of the

angle irons

44 and 45 to reinforce the fuel burner supporting structure.

An angle-iron brace 48 is secured to the vertical legs of the angle irons 44 and 45 a short distance below the track portions 46. This brace adds rigidity to the fuel burner supporting structure and, as shown in the modification illustrated in Figs? and 8, may also support the lower rear end of the fuel burner when the same is installed in the range body. This brace member is preferably bolted to the

angle irons

44 and 45 so that it may be readily removed therefrom when the fuel burner is being inserted into or removed from the fuel-burner compartment.

The fuel burner 2! has been shown somewhat diagrammatically in the drawings since the structural details thereof are not important to the present invention. The fuel burner is shown as generally rectangular and will usually have an uper fuel-burning space accessible through an upper opening closed by a door 5| and a lower ash-receiving space separated therefrom by suitable grates and accessible through an opening closed by a door 52. The grates may be shaken by means of a shaft 53 (Fig. 1). The fuel burner is provided with a smoke box 54 at the rear end thereof provided with a flange 55 adapted to be connected to a suitable flue.

The top of the fuel burner unit is provided with an opening surrounded by a flange 56. As shown in Fig. 5, wherein the fuel burner is installed in the range body, it will be noted that the flange 56 is substantially coextensive with and lies immediately below the opening 35 provided in the range platform M. This flange projects above the lower surface of the H-shaped structure 3!, so that it would not be possible to slide the fuel burner horizontally along the tracks 46 into the fuel burner compartment.

The flange 56 supports a top plate 51 (Fig. 5) which is slightly smaller than the rectangular opening 35 provided in the platform it. This plate is provided with a depending flange 58 coextensive with and removably engaging the flange 56 of the fuel burner. The top plate 51, as shown in Fig. 5, is preferably disposed slightly above the plane of the platform [4. This top plate, as shown in Fig. l, is provided with removable lids 59 and vents 6i and may be used for cooking.

The rectangular portion of the fuel burner is of such width that it may pass between the inner edges of the track portions 46 of the

angle irons

44 and 45. Consequently the side walls of the fuel burner, when the latter is assembled in the range body, are spaced from the

side walls

24 and 28 of the fuel burner compartment to provide spaces through which air heated by the hot side walls of the burner may rise and be discharged through the vents Si in the top plate for heating the room.

By making the fuel burner narrower than the space between the tracks 46 of the fuel burner supporting structure, the fuel burner may be inserted into the range body without dismantling the latter. The manner of inserting the fuel burner into the fuel burner compartment [9 of the range body is shown in Fig. 4. .By reference to this figure, it will be noted that the front of the fuel burner is provided with a flange 62 at each side thereof. These flanges have opening therein which align with openings 53 provided in the abutment flanges 42 and 4.3. The lower ends of these flanges terminate in or are provided with horizontally-extending portions 34, each of which receives an adjustable screw '65 which serve to support the front of the fuel burner on the tracks 45. The rear of the fuel burner is provided with a pair of brackets 66 bolted to the .fuel burner at each lower rear corner and which carry adjusting screws 61.

Installation of fuel burner To install the fuel burner in the range body, the range body is set approximately four feet from the wall against which it is to be placed in use. The rear angle brace 49 is removed from the L-shaped angle irons M and t5 and the rear brackets 66 are also preferably removed from the fuel burner. ihe fuel burner is then set close to the rear of the compartment 19 and the front end lifted, so that the front adjusting screws 65 rest on the tracks 46. The fuel burner is then pushed forward into the compartment while keeping the rear end of the burner down to let the upper front of the fuel burner, and particularly the flange 56 carried by the top thereof, to pass under the rear strip 32 of the H-shaped member 3| of the range frame.

When the burner .has been pushed into its extreme forward position, the rear end is then raised and the brackets 55 attached to the lower rear end thereof. This brings the adjusting screws 67 into the position shown in Fig. 5, so that they will support the rear of the fuel burner on the tracks 46.

The front adjusting screws 65 are preferably set at a predetermined distance from the top of the flange .55 before inserting the fuel burner in the compartment, final adjustment of the fuel burner to level the same being made by the rear adjusting screws 61. had been removed to permit the fuel burner to be inserted in the compartment 19 may now be replaced and the front flanges 62 of the fuel burner secured, as by means of stove bolts, to the

flanges

42 and 43 carried by the

side walls

24 and 28 of the compartment. The top plate 51 is now lowered into the opening 35 in the platform to complete the assembly.

In Figs. '7 and 8, there is shown a slightly modified adaptation of the invention, in which the rear brackets 66 have been replaced by a single bracket 68 fastened to the lower rear end of the fuel burner. This bracket is provided with two adjusting screws 69, only one of which is shown, which are adapted to rest on the cross brace 49 for supporting the rear end of the fuel burner in its final assembled position.

While the invention has been shown in several forms, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and it is desired, therefore, that onl .such limitations shall be placed thereupon as are specifically set forth in the appended claims.
