My invention relates to portable stoves, more especially to a portable camp stove adapted to be carried on an automobile and set up at any desired place for cooking or heating purposes. My invention also provides a stove provided with a plurality of cooking devices, all of which may be enclosed within the casing to form a compact portable stove, or any of which may be held in position in the casing for cooking purposes. In the drawings: Fig. 1 shows my stove packed and carried on the running board of an automobile; Fig. 2 is an end view of my stove open and ready for use showing a broiler in position; Fig. 3 is a view of two supports for the oven; Fig. 4 is a front view showing oven in place for cooking; Fig. 5 is a view of my broiler; Pig. 6 is a view showing a top on stove for cooking; Fig. 7 is a view of a device for attaching stove to running board of an automobile; Fig. 8 is a sectional view through the center of Fig. 4.

SIn the drawings in which like characters refer to like parts, I is the casing of my stove which is open at top and bottom. 2 is a cover attached to casing I by hinges 3 and held, when open, by bars 4 so as to form a horizontal shelf upon which articles may be placed. These bars 4 are removably held on a pivot pin 6 and 7 on the casing I and cover 2 and are so arranged that when the cover is closed the bars 4 may be placed on the pins to hold the cover 2 in closed position. Within the casing I is fixedly attached by bolts, spot welding or otherwise, angle irons 7 which may be short as shown in the drawings or may extend the entire length, or any portion thereof, of the width of the casing wall to which they are attached. These angle irons 1 form supports for a grate 8 which may be of any type forming a foraminous foundation upon which to support a fire. The grate 8 should have sufficient openings 45 for air currents to pass up to the fuel. I prefer, however, to have the grate provided with an upwardly extending flange 9 spaced apart from the wall of the casing, as shown, to provide space for air currents to pass upward around the grate between the casing wall and the flange 9. In the casing wall arranged below the grate I provide openings 10-10 to also provide for air currents or drafts to pass into the casing below the grate.

These openings may be as numerous as desired and are preferably located in walls on all sides of the stove. Upon the grate 8 may be placed any suitable fuel such as charcoal, etc.

In opposite walls of the casing I provide a number of slots or openings 11, 12, 13, 14, open at the top and extending downward in a general direction toward the bottom of the casing. These openings correspond and cooperate with arms or bars which support various cooking devices in place while being used and also when the casing is used as a container to contain and carry the stove, and the cooking devices or portions of the stove devoted to different uses, such as baking, frying, broiling, etc.

In the drawings, 16 is a baking oven having a removable top 17. This oven is a metal casing provided with a bottom thereby forming a box and a removable top 17. The oven 16 is preferably of a size so that when placed within the casing a space for air currents is left between the outside of the oven 16 and the inner side of 20; the casing 1. 15, 15 are rods or bars preferably having flat surfaces to support the oven 16 in the casing I. These bars are provided at their ends with hooks 18 so arranged as to engage in the slots or openings 14, 14 on opposite sides of the casing I, thereby forming a cradle to hold the oven 16 within the casing but above and spaced apart from the grate. When the oven 16 is placed in the casing I and the fire is ready, the food to be cooked is placed in the oven and the removable top placed in position. Small lugs 19 on the edge of the oven walls are provided to engage with openings in the top 16 to center same in place.

The removable oven top 1I also serves as the stove top for frying, boiling and other like uses.

The top is provided with extension arms 20 consisting of metal rods preferably larger than the top and fixedly held in flanges formed on opposite edges of the top 17 by bending the metal of the top around the metal rods. The ends of the rods extend out from the top and are at the ends bent at an angle to the top to form hooks. The arms 20 on one side of the top when the top 17 is45 used as a stove cooking top, engage in the slots 13 on opposite sides of the casing I while the arms on the other side of the top 20 rest on the top edge of the casing, being held in position against shifting by the arms in the slots 13. The top 17 is provided with an opening 21 over which may be placed any cooking utensil. In Fig. 6, I have shown the oven 16 without the cover 17, inverted on the cover 2 to form a warming compartment for dishes, cooked articles, etc. I have also shown a frying pan and coffee pot in position on stove top 17.

In Fig. 5, I have shown a broiler 22 of ordinary form but provided with an extension arm 23 and an extension handle 24 arranged opposite each other. The arm 23 engages in slot 12 in one of the casing walls and the handle 24 shank engages in the opposite slot 12 to support the broiler in position above the grate. The shank of the broiler handle 24 is preferably made wider in a vertical direction to the horizontal so that the broiler cannot turn in the slot 12 as shown in Fig. 2. This widening of the handle results from providing each of the two members of the broiler with handles as shown in Fig. 2.

When it is desired to turn the broiler in cooking, it is raised out of the slot 12 at the handle end having the other end in the opposite slot 12, then turned and the handle placed back in its slot 12. As will be seen from the above, my stove casing and its parts are all capable of cooperating to form a compact portable camp stove. When it is desired to transport the stove, the oven is placed into the casing without the top so as to form a tray into which may be placed various cooking utensils. Above this and as a cover for the oven, now a tray, is placed the oven top 17.

In manufacturing my stove, I prefer to so form the space above the grate that it will permit the oven top 17 to rest on the oven when it is resting on the grate. Above the top 17, I then place the broiler and then the cover 2 is folded over to close the casing. When the casing is so closed, the edge of the cover flange engages with the extension arms of the broiler and holds same against the top 17 which is thereby held on the oven top.

This forms a means of packing the parts within the casing so that they may be readily carried without disarrangement, and with little if any rattle, on the running board of an automobile.

To fixedly attach the casing and its contents to the running board of an automobile, I provide attaching device shown in Fig. 7 consisting of a rod bent to form an arm 25 having a short hook 26 and a longer hook 27 to which it attached a member 28 parallel to the arm 25. This member 28 is provided at its free end with a screw threaded opening through which is a screw bolt 29 having a handle or cross bar 30 to operate it. The hook 26 and arm 25 of this attaching device are passing through one pair of openings 10 on opposite sides of the casing I so that the hook 26 extends on the outside of one side of the casing, and the larger hook 27 on the outside of the opposite side. Then the member 28 is placed under the running board, the bolt 29 turned until its free ]0 end is held in close contact with the underside of the running board thereby holding the portable stove fixed on the running board.

It will be seen from the above that in use the cover is turned over and forms a support upon which the oven may be placed, thereby forming a warming compartment into which dishes or food may be placed while additional food is being cooked on the broiler or frying top. By providing the openings in the casing below the grate the stove may be placed on the ground and a suitable circulation of air is provided through the openings to feed the fire on the grate. If desired one or more of the openings may be closed by placing a flat strip of metal or other suitable material against the casing.

I claim: In a stove, a casing, a grate of less area than the inside of the casing arranged within said casing so as to be movable horizontally therein and removable therefrom, said casing provided with means for supporting said grate intermediate the upper and lower edges of the casing, openings in said casing below the grate supporting means, a plurality of slots arranged in opposite sides of said casing extending downward from the top thereof, removable means adapted to fit within said slots to support cooking utensils above said grate, a cover for said casing having a downwardly extending flange so arranged that when said cover is closed the lower end of said flange engages with the said means in the slots in the casing to hold said means against a vertical movement therein.
