FIG. 13 is a sectional View similar to FIG. 12 but showing the lifting implement applied to the inverted frying pan stove cover, and

FIG. 14 is a fragmentary perspective View of a portion of a strap brace for support of a rotatable spit.

Referring now more particularly to the drawings, there is shown in FIGS. 13, a preferred embodiment of the stove according to this invention as comprising a stove, or firebox, compartment generally indicated at It and an oven compartment generally indicated at 80, the oven being installed on the stove in FIG. 1 but removed therefrom in FIG. 2 and folded and collapsed for storage within the storage compartment in FIG. 3.

The stove comprises front and

rear walls

12 and 14 respectively, a bottom wall, not visible in these views, end walls 16 and a partially covering top wall 113. These walls enclose and form the stove chamber or fire box, the opening at the top being adapted to be covered by the removable closure 2%. Inside the stove is a grate 22 upon which may be placed the fuel to be burned, said grate being removably supported on

cleats

24 and 26 at different levels. The top wall 18 has an opening 39 to removably receive a short chimney 32 which carries a damper operable by the protruding handle 34. To permit entry of air and further control the draft, a sliding partition 36, having a hand grip flange 38 at one end and a plurality of vent openings 40 is provided. This partition is slidable in track flanges 42 formed on a separate panel 44- which is hinged at the bottom edge of one of the walls 16 by means of the piano hinge 46. Panel 2-4 has openings 48 similar to openings 4% (see FIG. 2) so that upon movement of the draft panel 36 to change the registry of the

openings

40 and 48, the draft of air into the fire box may be modified. When the damper panel 44 is moved outwardly on the piano hinge 46, the lower part of the stove under the grate 22 is accessible for removal of ashes.

A pair of tubular handles 50, each bent into U-shape, are pivoted at their free ends to the end Wall 16 by pivot means 51. Consequently, when the stove is to be carried, the legs may be moved to an upper position as shown in FIG. 3 wherein the transverse portions, or bights of the Us 52 may be grasped for lifting the stove. When the stove is to be stored, the handles 50 may be turned in the direction of the arrows as illustrated in FIG. 3 to the broken line positions shown in which the bight of one handle lies adjacent to and against the top surface of the stove at one edge and the bight of the other handle lies against the lower edge of the front surface 12. Thus disposed, the handles occupy a minimum of space since they rest directly against the stove casing.

The store 19 may be supported above a surface by turning the legs 5% on their pivots to occupy a downwardly extending spread position such as in FIGS. 1 and 7. The legs are secured in such position by a brace strap 54- which has an angle cross section including a flange 56 which seats under the lower edge of the stove. At each end, flange 56 has an inturned finger 57 which together embrace the

stove walls

12 and 14 and prevent longitudinal movement of the brace. The ends 53 of the brace are curled inwardly to slidably grasp the legs when positioned thereover and are directed at angles so as to hold the legs in spread condition. Portions 58 are spaced at their free edges from the body of strap 54 so that the brace may be lifted away from the legs 50 without neces sarily sliding the complete lengths of the legs into the brace. As clearly indicated in FIG. 7, the strap flange 56 comes to rest under the stove so that further sliding movement, which would otherwise be caused by the weight of the stove, is prevented and the stove is firmly positioned on the legs as shown.

As indicated in FIG. 6, the stove may rest on its bottom wall with legs 50 tunred upwardly to diverge from each other. In such instance, the brace 54 is inverted and the curved ends 58 again slidably engage the legs while the flange 56 comes to rest on the upper edge of the stove preventing further spreading movement of the legs.

With the legs in this position, as best illustrated in FIG. 2, a pair of angle straps 60, somewhat similar in shape to the brace 54, may be disposed over the bights 52 of the legs by means of curved end portions 62. Centrally, one strap 60 has, welded or otherwise suitably secured thereto, an upstanding finger 64 having a circular opening 66 to act as a bearing for spit 140. The other strap 60 is provided with a similar finger 68 (see FIG. 14) having a groove 69 in its upper edge for receiving the spit.

A pair of detachable trays 70 are provided for extending the work surface of the stove at its front and rear. Each tray is formed with a downturned peripheral flange 72 with cutouts 74 at the inner corners to permit the trays to be slid inside the upstanding

vertical walls

12 and 14 of the stove with the flanges 72 engaging the inner surfaces of such walls. Each tray is then supported in position by a pair of triangular shaped wire braces 76. Each brace is preferably an obtuse angle triangle with one side engaged in hinges 78 at the under side of the tray 70, a second side engageable with the walls 12 and '14 of the cook stove and an angle point bearing against wall 72. of the tray. The brace, when so constructed, bears against the cook stove at only one point which is below the high heat area. The braces may be folded in their hinge mounts 78 to lie flat within the confines of the flanges 72 when not in use and in such condition may be stored within the stove It} with the other accessories.

The collapsible oven '80 comprises an upper horizontal panel 82 having downturned peripheral flanges 84. A pair of end walls 86 are hinged to the flanges of upper wall 82 by means of piano type hinges 88. At various levels, the end walls 86 are provided with keeper brackets 90 for reception of removable shelves, not shown. At the vertical edges of each of the end walls 86, are hinged front and

rear panels

92 and 94 respectively. The two rear panels 94, when folded into alignment, form the rear wall of the oven and are secured in such position by engagement of the upper edges of the panels with the flange of the top panel and by engagement of the lower edges of the panels with the inside surfaces of the upper edge of the stove wall 14. The front panels 92 are slightly shorter in length than the rear panels 94 and are [thus openable over the tray 7) when positioned on the stove at the front thereof. One front panel 92 has a keeper latch 96 adapted to engage behind the downturned flange 84 of the top panel to hold the doors in closed position. An aperture 98 is also provided in panel 92 for reception of an oven thermometer 1%.

Each oven side panel 86 is provided with a bearing opening 1&4- for the spit and, at its lower edge, with a pair of outturned brackets 166 which, when the oven is unfolded and inserted in the stove top, serve to support the oven by resting on the stove bracket 108, as best shown in FIG. 10. The outturned portions of brackets 166 will, in that position, fit under the downturned lip 17 formed peripherally on the upper edges of the stove walls. When the stove cover 20 is seated within the oven on the bracket 16% of the stove, the cover will press outwardly against the brackets 106. This holds the oven unfolded and locks the oven to the stove 10 against upward removal of the oven because of retention of brackets 1% under lip 17. The stove and oven will, therefore, be connected to operate as a single unit and cannot be dissassociated until the cover 20 is first lifted and removed from the inside of the oven. The same locking function is performed by the closure 20 when it is inverted and inserted for use as a frying pan. Alternatively, the pan 21'} may be replaced by a grill 110, FIG. 9, which also locks the stove and over together. FIG. 4 shows the relation of the various panels comprising the oven and indicates in the numbered sequence 1-6 and the directions of the arrows how the panels may be folded on their hinges to occupy a minimum of space. To collapse the oven, each end panel is turned upwardly and toward the upper panel 82 with the front and rear panels hinged thereto turned outwardly in the direction of the arrows. In the collapsed condition, FIG. 5, each panel lies adjacent the next one and all are confined the space bounded by the flange 84 of the top panel 82 which has been inverted and is now at the bottom of the stacked panels. When collapsed, the oven will easily fit Within the stove casing for storage or transportation.

To open the oven after inversion, to place panel 82 on top, it is apparent from FIG. 4 that the end panels 86 are turned downwardly and the front and rear panels are then turned outwardly in directions opposite to the arrows of the figure.

In FIGS. 11-13 is shown a lifter implement for removing, or inserting, the frying pan stove closure 20 from the oven through the open oven doors 92. The lifter comprises a handle 122 made of a rod bent into an elongated U-shape and Welded, or otherwise secured, at the free ends to the upper surface of a short channel member 124. The horizontally disposed web of the channel 124 has an integral downturned flange 126 with a slightly inturned lip 128 and a shorter downturned flange 130 having an inturned lip 132. Spaced closely adjacent to the flange 126 and fixed to the under surface of the web of the channel 124, is a bracket 136 having a downturned flange parallel to flange 126. As shown in FIG. 12, the upturned edge, or flange 21, of the frying pan 20 fits between the

fianges

126 and 136 of the lifter so that upon slight turning of the lifter and upward movement thereof, the frying pan flange will be held by the lifter to move therewith. If the frying pan 20 is inverted, as shown in FIG. 13, a detent bracket 138 secured to the under side of the frying pan and having a right angle flange engageable over the lip 132 of the lifter while the flange and lip 128 of the implement bear against the flange 21 of the pan to hold the pan for lifting. Thus, one implement 120 is usable to lift the frying pan whether it is in its normal or inverted position within the oven or on the stove with the oven removed.

When the oven is assembled, as shown in FIG. 1, it may be used with shelves inside to hold food to be roasted or baked, or the spit 14%) may be inserted to rest with its end-s rotatably supported in the openings 104. The spit is provided with conventional type forks 142 which are detachably secured thereto by screws having wing nuts 143, as shown in FIG. 2. The spit is adapted to be operated as an oven rotisserie turned by a motor contained in the housing 144 which also may include dry cells, or the like, for energizing the motor. In FIG. 2, the rotatable spit is mounted to turn in the bearing

brackets

64 and 68 forming part of the support straps 66 and having the bearing

openings

66 and 69, as previously described. In this view, the spit, which can be turned by hand, is shown as being turned by an electric motor housed in the casing 146 and having a cord 143 for connection to a source of electric power.

The entire stove is made of metal or other suitable material of sufficient strength to support the cooking utensils and maintain its shape under the heat generated therein. Various parts of the stove, oven and accessories are suitably painted, enameled orplated to present a pleasing appearance.

It will be readily apparent from the above description that the present invention provides a portable camp stove which is versatile to perform all kinds of cooking in virtually any location. When set up as in H6. 2, it is adapted to charcoal broil, smoke cook, barbecue or fry. And, when set up as a complete oven and stove combination, as shown in FIG. 1, it is adapted for use in baking, roasting and other types of oven cooking. The damper provided in the chimney and the adjustable openings 4d, a? in the fire box door 36 permit the regulation of the fire and the temperature needed for the cooking at hand. These, together with adjustable cast iron grates enable all types of fuel such as wood, charcoal, coke, etc., to be used. It should also be clear from the above description that the camp stove may be quickly set up, or taken down, and that when the oven is collapsed and packed with all the accessory parts in the stove compartment, the device occupies very little space and may be easily carried by means of the handles which, during use of the stove, function as legs or spit supports.

Although a certain specific embodiment of the invention has been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claims.
