" \desirable.etherefore, to carry a stove as part of the equipment for such trips. Because storage `space in the luggage or other storage compart- 15 ment is usually taken up with traveling bags or y other camping equipment, the stove should be collapsible so as to require a'minimum amount oi' space.' y An object of the present invention is to provide so a foldable camp stove or the like whichrcan be compactly folded or stored ina 'siall space and which is equipped with foldable accessories which facilitate the preparation of meals on the stove.

This object is attained by providing a frameu like member to which all of the elements of a stove, which are all substantially dat, are pivotally mounted, and are movable into face-toface relation to form a thin compact unit.

Preferably, the stove comprises a grid pivotally 30 mounted to extend across the frame-like member and upon which food can be cooked.l Disposecllnelowihe grid\a1g apair`of\side walls which are pivoted at their upper edgs`to. the frame-like member.and have their free lower 35 edges disposed adjacent one another to form a trough-like iirebox for receiving wood, charcoal, or other fuel. The side walls, being movable` about the upper edges, are foldable into nested relation with the undersurface of the grid, when o collapsed.

. 'I'he grid and rebox of the present invention are supported at a suitable, distance above lthe n NM" grounff'tpermit the `ilre to burn properly and place the grid at a convenient height by end a members which include legs or other supporting means. The end members are pivoted to the frame by means of offset hinges so as to move about their upper edges and into engagement with the upper surface of the grid. .The end lo members can be provided with walls which, when moved into operative relation with the side walls, will substantially close the ends of the iirebox. With the side plates folded into engagement with one face of the grid and the end members into engagement with the other face of the grid.

193s. serai No. 226.642 (o1. 1re-2a) a very thinat and compact assemblage is obtained which can be readily stored in small spaces in the luggage or other storage compartment.

aWhen the stove is unfolded, means are 'pro' rvided frengaging and holding themslde walls in 5 proper position to form a firebox and for holding the end members against movement about their pivots and-in proper position to support the grid. In the preferred form`6fthe"lnvtlbnthis'comprises interenggicghmvens on the side walls andm`V end members, w en -moved into engage- .ment, hold the walls in interlocked relation against movement about their pivots and provides a rugged and easily operated device. When food is to be'cookedrit is Yoften to nd a place upon which it can be spreaddu ing its preparation for cooking, Accordingly, the presentl invention provides a novel table unit adapted to be mounted in conjunction with the grill or stove so as to have one side supported zo thereby. Y,'I'he other side of the table is provided with apair of foldable legs for supporting the table top insubstantially the same plane\as the top of the grid. This will aord ample space for preparing the meats or` other materialto be Ig5 cooked on the grill. When the table is folded, it can be readilynested with the folded stove for storage.

A further accessory,` which is now essential with the advent of toasted sandwiches, comprises 30 a means carried by the grill and'l disposed adjacent the iirebox for receiving bread or the like for toasting. Preferably, this comprises a rack suspended from the grid or frame so as to be adjacent the portion of the iirebox carrying the 35 vhot coals, whereby the intense heat will quickly `brown the bread to the desired extent.

Another' problem' eiuntered/"in foldable stoves or grills is that of cooling the parts thereof after it has been used. According to the present o invention, the grid and parts of the side walls which support the iire in the rebox are formed of expanded metal sheets which have a minimum mass and do not unduly retain the heat so that they cool very rapidly after use and permit the 45 grill to be stored quickly after the meal has been prepared. Furthermore, the use oi the expanded metal in the side walls affords an ample draft for the burning of wood, charcoal or other fuel used with the grill.

Other features and advantages of the invention will be apparent from the speciilcation and claims when considered in connection with the drawings, in which:

Fig. 8 shows another form of mounting the end member.

20 Fig. 9 shows 'another form mounting therefor.

As illustrated in the drawings, the foldable camp stove of the present invention comprises a pair of end brackets III, II having their ends of side wall and 25 connected by a pair of rods I2, I3 so as tofrm a.`T

substantially rectangular frame.

A grid Il is plvotally mounted so as to extend across the framehn the preferred 'form of the inventionasshown FigVfth-e grid comprises frame is or band-nire material aaaptedicheJ-/Tidlspprtedeata-slsbie height above disposed within the rectangularrame, and is provided with a supporting surface'of expanded metal I6 extending thereover and secured in place by having the edges I1 thereof bent inwardly to 35 enga etheinner surface Voi' the band-like frame J' be welded thereto.

The supporting surface is braced and prevented from sagging by means of a rod I8 or other bracing means secured to theframe and 4 0 engaging the center of the underface `of the supporting surface as shown in Fig. 7. i .-.er

The end walls of the band-like frame of the grid are provided with aligned openings adjacent one side thereof for receiving the rod I2 so that the grid pivots about the rod, and a pair of aligned slots 20 are formed in the end walls adjacent the other side of the grid so as to receive the rod I3 and hold the grid against shifting. If desired, suitable means can be provided inthe form of a handle or tool for moving the grid about its pivot into an open position.

The rebox for the stove is formed by a pair of

side walls

25, 26 disposed below the grid. Preferably, the side walls are hinged at their upper edges to pivot about the rods I2, I3. While the side walls can be formed of any suitable conpocket to receive, in overlapped relation, a portion of the expanded metalsheet 2l which forms the remainder of the wall. A strip of metal 33 overlies the overlapped portion of the expanded metal and hinge plate and the overlapped por- 6 tions are secured together by welding or the like.

In assembling the side wall of this form of the invention, it is merely necessary to makeup the sidewall by vassembling the hinge plate, sheet of expanded metal and metal strip and securing l0 them together. 'Ihe bentover edge is then positioned around the rods I2 or I3 and crimped into engagement therewith so that it is pivotally movable about the rod as in the previously described form of the invention. l

The two side walls are so disposed with respect to the frame that, when their free ends are adjacent one another, they form a trough-like flrebox as shown in Figs. 1 and 'I and the expanded metal forms suitable l draft openings therefor. The amount of draft is controlled by the amount to which the sides of the hinge plate extend over the side walls. The closed toprofetheside walls not ODImntmISJheraIt'bFaI/So prevents coldmcf/k airefrtm circulating under the grid and interfering wlththe cooking.

It is to be understood that, if desired, the side walls can be entirely of expanded metal, and a shield provided fp r controlling Vthidraft.

end members

35, 36,

which are pivotally mountedtothewpvracketsfr" II so as to move abut the upper edge thereof.. In the preferred form of the invention, the brackets are provided at their ends with outwardly projecting

lugs

31, 38, and each end member is formed by a pair of

crossed legs

39, 40, secured together at a point intermediate the ends. The upper ends of the legs are bent through a 90 angle al ong al line extending at an angle trans- Aversely of the leg s'o a'sto provide a pair of offset hinges 4I for engaging the sides of the'lugs 31, 38 and receiving pivot pins l2 carried thereby asV shown in Figs. 2 and '7. 'I'he end members, when moved about the pivots from the supporting position through a reex angle of substantially 270 as shown in Fig. 5, will move into contact with the upper surface of the grid. l

` If desired, the end members can be provided with an end plate I3 which, when the end members are in supporting position. will close the ends of the nreboxs; g ,y v

In order to hold the stove in extended position, suitable means must be provided for limiting the movement of the side walls and end members about their pivots. While this may comprise sepstruction, in the preferred form of the inventiorL aites'eming means for holding each of the have a sheet of expanded metal 28 secured thereto. In the illustrated form of the invention, the

body of the hinge extends across a portion of the side and has positioned .between the sides 29, 30 thereof, at the open end, the strip of ex- 55 panded metal which is clamped bythe sides of the hinge and held in place. The strip of expanded metal extends for the remainder of the width of the wall to the free edge thereof. 'Ihe exposed edges of the expanded metal are preferably 7o covered by a thin metal band 3I folded thereover. Another form of side wall construction is shown in Fig. 9, in which the hinge plate comprises a. strip of sheet metal having its upper edge folded over as at 21' and provided at its lower edge with an offset section 32 which is adapted to form a pair of ears or tongues M dissd atan"angle-`\ 'f to the top s0 as to be tangent to or extend along an arc of a circle having the rods I2, I3 as cen- 65 ters. Each of the side walls is provided with a slot 85, as shown in Fig. 2, for receiving lthe tongues when the endv walls are moved about their pivots and are in extended position.

The portion 43 of the tongue of this novel 70 interengaging means provides a stop for limiting the downward movement of the side walls about their pivots so that they form the flrebox as shown in Fig. 7. 'Ihe weight of the sides tend to maintain the side walls against the stop and I5 arcaica keep the slots and tongue in interlocked relation. 'Ihe slot's. being normally interlocked with the upstanding portion of the tongue, will hold the ends from moving outwardly about the pivots, and will form a very stable construction. j

As will be noted from Fig. 7, the

rods

12, 13 about which the side walls and grid pivot, and the pivots 42 for the end members are all disposed in substantially the same plane, with the axes. about which theside and end walls pivot, being disposed at right angles to one another. This enables the side walls and the end walls to be moved into compact relation with the grid. As shown in Fig. 4,- the side walls will be moved through an angle of less than 90 into nested relation and into face-to-face engagement with the undersurface of the grid, and, as shown in Fig. 5, the end members will be folded into at face-to-face engagement with the upper surface of the grid through an angle of more than 180,

all moving about pivots in the same plane and without interfering with one another so that a very thin and compact device is present when folded.

In another form of end construction, one end being shown in Fig. 8, the lugs 31' on the end brackets I i' are folded back so as to be in parallel relation to the sides of the grid frame. The hinges 4 I are formed on the legs and are turned in the reverse direction to that described in the previous form of the invention and receive the pivot pins 42'. The legs, as now mountedvare limited in moving to supporting position so as to be at right angles to the grid, as shown in dotted position in Fig. 8.

When it is desired to fold the camp stove of the present invention, using this type of end member, the side walls are folded into engagement with the undersurface of the grid and the end walls are then folded as indicated by the arrow intoengagement with the undersurface of the side walls. With all of the walls pivoting about pivots extending in the same horizontal plane, a very thin and compact structure will be formed.

When it is desired to set up the stove incorporating this form of end wall, it is merely necessary to grasp the end stove by the end .brackets and permit the end members to pivot into the dotted position as shown in Fig. 8,at which time the side walls will be released and dropped into proper position with the slots engaging the tongues on the end walls and holding the unit in extended relation.

In either form of the invention, the stove can be very readily sc t up by first moving the end members about their pivots and disposing'the tongues in the path of movement of the side walls supporting the re and the gridv disposed' over the fire are made of expanded metal having considerably less mass than would solid material so that it cools very rapidly, and enables the grid to be handled for storage.

If'desired, the device may be rust-proofed in any suitable manner to prevent the metal from rustingdurlnguseindampplacesorduring me When 'cooking in the out-of-doors, it is desirable that Ysome meins be provided upon which the food to be cooked can be prepared. According to the present invention, a foldable table il is combined with the stove for this purpose. As shown in the drawings, the table comprises a rectangular frame 5i having a top` Ilthereon. A pair of lugs I8, il on the frame project beyond one side thereof, as shown in Fig. 6, and are provided with notches l5 in their undersurface adapted to engage and rest on the outstanding lugs 31, I8 of the brackets lli, il at the ends of the stove to be supported thereby. The other side of the frame is supported by a pair of legs I8, one at each end, pivoted to the frame at Il and having aportion I8 thereof engaging a stop pin 59 when moved intoextended position to properly locate and support the table in a plane which is a substantial continuation of the surface of the grid.

While the table has been shown as being disposed along the side of the grill, it is to be understood that the table can also be arranged to form a longitudinal extension of the grill by placing the lugs at the end of the table to engage the brackets on the stove to be supported thereby.

When the table is collapsed, it will t over the folded grill so that it adds merely the thickness of the table to the already compactly folded grill, and can be readily stored therewith.

With the advent of toasted sandwiches, means have been required for the toasting bread to be used, either before or after the-filling has been placed therein. While the bread may be placed on the top of the grid, the heat is usually not suiilcient to properly toast the bread, but will dry it' out before it has become sufficiently brown.

According to the present invention, a novel rack 6U is provided for' supporting the bread adjacent the side wall of the rebox and near the point where the embers of the nre are disposed, so that the intense heat found there will quickly brown the surface of the bread to the desired gx'tent without unduly drying and hardening the read.

In the illustrated formof the invention, the

rack is provided with a handle 6| whereby it can be readily manipulated for the insertion and removal of the bread. The rack is suspended from the grid or frame by means of a pair of arms 62 extending therefrom and into engagement with the frame or grid, and has the center of gravity so disposed that it swings about the arms and into engagement with the side` walls of the stove. A

'I'his accessorycan be nested over the edge of the folded stove so that it does not unduly enlarge the same, and `can be readily stored therewith.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others.
