This invention relates to cooking stoves and particularly pertains to a portable stove utilizing electrical current as a medium for heat generation.

It is the principall object of the present invention to provide an improved, compact portable cooking stoveof such dimensions and weight that it may be positioned for use on a table or like support, which stove is inexpensive to construct, pleasing in appearance and provides toasting, baking, frying, broilingand stewing facilities.

One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawings. in which:

Fig. 1 is 'a central longitudinal section through the stove embodying the preferred form of my invention.

Fig. 2 is a transverse vertical section through the same.

Fig. 3 is a plan section through-the stove.

Fig. 4 is an end elevation of the stove with parts broken away to disclose certain features of construction.

Fig. 5 is a fragmentary view in plan.

Referring more particularly to the accompanylng drawings, I have illustrated a portable cooking stove which is light in weight and of such dimensions that it may be conveniently arranged on a table or like support for use. The portable cooking stove includes an oven i0 which is formed of side walls Il and l2, a rear end Wall Hand a front wall I5. These walls are preferably of 'sheet steel and formed by die stamping.

, At the meeting edges of the side and end walls the 'latter are formed with right angularly turned flanges I6, the inner surfaces of which engage the outer surfaces of the side walls Il and l2.

'Ihe ends of the side walls Il and l2 abut against the innerl surfaces of the front vand Yrear walls I4 and i5. The four walls are secured together in any suitable manner such as by riveting the flanges I6 to the ends of the side walls II and i2 or byv welding along the seam between the flanges and the side walls.

To form a closure for the bottom of the oven I provide a horizontally disposed bottom plate il which is likewise formed of sheet steel of suitable gauge. The four marginal edges of this bottom plate are upturned a short distance to contact with the exterior of the side and end walls at the lower ends thereof when the same are assembled with the bottom plate. The side and end walls are then secured to the upturned marginal edges of the bottom plate either by riveting or welding or in any other suitable manner.

When the side and end walls are assembled with the bottom plate, the side surfaces of the oven are porcelain coated either by brushing or 5 spraying which when baked provides a seal at all the junctions between the various parts and gives vthe oven a pleasing appearance.

may discharge over the upstanding wall 20a of 2oy the skillet and prevent the same from depositing on the exterior of the oven. The npstanding wall of the skillet extends vertically from the bottom of the skillet and is formed integraktherewith. 'Ihis wall is rectangularly arranged in plan 25 and overlies the side and end walls of the oven so as to give the appearance of being a continu` ation thereof.`

At one end, the skillet is formed with a spout 22 which projects beyond the rear wall I4 of the 30 oven. This spout is substantially semi-circular in plan, as illustrated most clearly in Fig.. 5. At the bottom of this spout and spaced from the rear wall I4 of the oven the same is formed with a nozzle 23. A tapered port 24 is drilled vertical- 35 ly Vthrough the nozzle so that liquid matter accumulating in the skillet may be discharged through this port 24.

To control the discharge of liquid through the port, I have provided a plug valve member 25 40 which has a tapered lower end'fltting the taper of the port 24. I have found out that this tapered construction of the port 24 and plug valve 25 is such that the valve 25'will not stick or freeze in the port and can be turned and removed from the 45" vport freely, regardless of the temperature of the skillet. It will be noticed that the plug valve 25 extends vertically a distance above the upper edgel of the surrounding walls 20a of the skillet and is tted with a laterally projecting operating handle 50 26 which may be of heat insulating material.

For thepurpose of removing liquids from the interior of the skillet through the port 24 I have provided a container 21 which may be drawn from a single sheet of metal or which may be formed 55 of sheet metal or other suitable material in any desired manner.` I prefer that the exposed surfaces ofthis container 21 be given a porcelain. finish harmonizing with the porcelain finish of the exterior ofthe oven. One side of this container 21 is flattened in order that it will coincide with the rear wall of the oven. The upper edgeof this flattened side of the container wall is formed with outwardly and downwardly projecting latch members 28 which are adapted to engage latch openings 29 formed in the rear wall I 4 of the oven so as to latch the container in a position below the port 24 of the skillet, so that when'the port is open the liquid in the skillet I8 will discharge into the container 21. 4This container is provided with an outwardly projecting heat insulating handle 30 so that the container 21 may be readily detached from the oven and its' contents removed.

I have found it desirable to maintain the adjacent walls of the container 21 and the rear wall I4 of the oven out of Contactin order that the heat from the oven will not be transmitted to the container 21 and increase the temperature of the liquid accumulated in the container 21.."

For this purpose the wall of the container at the flattened side thereof, which is closely adjacent to the wall I4 of the oven, is formed with a plurality of protrusions which engage the wall I4 and maintain substantially all of the surface of the container 21 out of contact with the outer surface of the wall I4 of the oven.

Inasmueh as the bottom surface of the skillet I8 is substantially level,V if it is desired to entirely drain the skillet through the port 24, it is merely necessary to slightly upraise the front end of the oven so that the liquids in the skillet will readily discharge through the port 24 into the removable container 21.

It will be noticed that the bottom of the oven is provided with four supporting legs 3I which are preferably formed of metal and may or may not be provided with heat insulating buttons at their lowermost ends.

rigidly connect the skillet I8, the legs 3l and the oven together, an elongated bolt 33 is arranged vertically within each corner of the oven. These bolts 33 are projected upwardly through drilled vopenings in the legs 3l, the bottom plate I1 of the together. A false, bottom or baille plate -34 is arranged at a spaced distance below the bottom plate I1.of the ovenin parallelismtherewith and may also be secured in place by the bolts 33.

To increase the usefulness of the skillet I8 and enable it to be used for stewing and the like, I have provided a dished cover 35 therefor. This cover is preferably drawn from a single sheet of material and is preferably given a porcelain finish agreeing with that given the exterior surfaces of the oveny in order that it will harmonize therewith. The dimensions of this cover are such that its lowermost end will snugly fit the skillet at the upper edge of the surrounding wall 20a thereof. Af bead 36 is formed aboutv the perimeter of the cover at a slightly spaced distance above its lower -edge so as to abut against the'top edge of the walls 20a of the skillet so that the cover will snugly t in place and be supported over the skillet.

At the center of the cover and projecting vertically therefrom it is provided with a heat in- .f In order to simplify assembly work and to an opening 38 to which a hinged door 33 is fitted.

The opening 38 is rectangular in form and around its perimeter it is formed with a door frame which is drawn from the sheet of material forming the front wall I5. 'I'his frame is so formed that when the door is fitted thereto, the latter will lie at an acute angle to the vertical. That is to say, the lower edge of the door vwill be spaced further from the plane of the plate I5 than its upper edge.

'I'he door 39 is formed of a sheet of material which is recessed at its center portion to snugly` t within the inner periphery of the door frame.

The marginal edges of the' door are adapted to abut against the front surfaces ofthe door frame. At the lower edge of the door, tangs are formed which are curled to nest within apertures cut in the bottom jamb of the door frame. Similarly curled tangs are formed in the bottom jamb of the door frame so that when a hinge rod 40 is projected therethrough, an articulate connection will be formed between the door and the lower portion of the door frame. It will be noticed, however, that when the door is open, as il1ustrat ed in Fig. 1, the lower marginal edge thereof will engage the underside of the door frame so as to support the open door in a horizontal position.

It will be noticed that there is a convex panel fitted to the door 38 and nesting Within the dished portion thereof. This panel is preferably given a porcelain finish to harmonize with the skillet cover 35 and the sides of the oven. A handle 4I is secured to the oven door and projects outwardlyto provide a means by which the oven door may be manipulated.

Arranged within the oven just beneath the skillet is an electrical heating element 42. Likewise, arranged within the oven at a spaced distance above the bottom thereof but below the loweredge of the door opening 38 is a. second electrical heating element 43. These heating elements are, of course, electrically connected together and to a socket 44 at the rear of the oven to which current may be led as in standard practice. These electrical heating elements supply heat for the oven and for the skillet I8 and it may be stated here that I may use any preferred type of electrical heating elements for this purpose. *t

Arranged horizontally within the oven at oppositesides thereof is a pair of guide rails 45 which are formed by die stamping and which are the door opening 38. The foremost ends of f these guide rails project into the door opening, as

illustrated, and in alignment with'these guide rails thefopposite sides of the door frame are recessed to receive them. That is to say, the lateral dimension between the inner side surfaces of the guide rails exceeds the lateral dimension between the sidesvof the door opening 38 so that the door opening is recessed at its sides just above the bot.- tom thereof to accommodate these rails.

The rails. arev arranged in parallelism and are .channeled in cross section so as to form a guiding and supporting means for a.A removable oven-pan or tray 48. The transversedimension of this tray is slightly less than the transverse dimension between the inner vertical surfaces or the guide rails though greater than the transverse dimension of the oven door opening so that the only place the pan or tray can be inserted into the oven is in alignment with the guideways adjacent the bottom of the oven door opening 38. This prevents any chance of contact between the pan and the heating elements because after the tray is inserted into the guideways, their channeled cross sectional shape maintains the pan in a perfect horizontal position both during insertion and withdrawal thereof.

To withdraw the pan, I have provided a pan extracting rod 41 which projects through an opening in the bottom of the door frame and which extends longitudinally of the oven beneath one of the guideways. It will be seen that this rod is located at one side of the door frame and at the bottom thereof. At the rear of the oven this rod is upturned and projects into the guideway through a slot 48 formed in the. bottom thereof and fitted with a head 41a above the guideway. This slot permits this upturned end to4 be reciprocated along the guideway. Therefore, when the pan is disposed in the oven, this upturned end of the rod 41 will be at the rear thereof and when the rod is moved forwardly.

l this upturned end will engage the rear end of the pan and cause the pan to be projected outwardly through the oven door opening. It is seen that at the forward end of the rod exteriorly of the oven it is bent laterally and projects beyond the side of the oven where it is provided with a heat insulating handle 49 by means of which the rod may be manipulated. It will be noticed that the door frame is formed with a socket to accommodate the laterally directed portion of the rod so that the latter will not interfere with closing of the oven door.

When the tray is placed in the oven, it will engage the upturned rear end of the rod 41 and if the rod is in projected position it will move it rearwardly of the oven until the tray is positioned. When it is desired to remove the pan, the oven door is opened, the handle 49 grasped and the rod 41 drawn forwardly. The upturned rear end of the rod will engage the rear end of the pan and move the same through the door opening.

, In order that the food in the pan may be observed to note the cooking progress in the oven. the side walls of the oven H and I2 are each fitted with a transparent panel 58 which may be of pyrex or any other transparent material which does not deteriorate under heat.

' To enable the entire stove to be easily moved from place to place, handlesv 5| are arranged one at each side of the oven.

In operation, the stove is constructed and assembled as illustrated and described and placed on a convenient support for use. This, if desired. may be on the table where the cooked food is to be served, as the stove is of such dimensions that it occupies but a small space.

When the circuit of the heating elements is closed, the oven and skillet will rapidly become sufiiciently heated for cooking purposes. The ordinary baking, broiling or toasting operations may be carried on within the oven and the progress of the cooking therein observed through the transparent panels in the oven sides. To extract the pan or tray on which the food is disposed from the oven, it is only necessary to open theA oven door and extract the tray by manipulating the tray extracting rod 41 by means of its handle 49. v

If it is desired to fry or stew food, either during the period the oven is in use or otherwise, the skillet I8 may be used. If it is .desired to remove accumulated liquids from the skillet, this may be done by draining the same through the port 24, the liquids discharging into the detachably mounted container 21.

I have found in actual practice that an entire meal may be fully and expeditiously prepared economically by means of the stove here disclosed and that said stove is an extremely useful device and adapted to a great variety of cooking and baking. Further, that the stove is pleasing in appearance and can be produced very inexpensively. 4

WhileI have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the artI without departing from the spirit of thefinvention as dened in the appended claims.
