2 Claims. (Cl. 126-,25)
This invention relates generally to broilers, :barbecue grills, and similar devices used for cooking out-ofdoors.
The main object of the present invention is to provide a generally improved device of the character described, and among more specific objects there are, among others, the following:
To provide a portable, convertible and collapsible charcoal broiler having a maximum area, in relation to the amount of charcoal used, over which heat is directed, thus to provide for the cooking of a substantial quantity of foods, despite the relatively small size of the charcoal compartment and the small overall size of the portable broiler;
To provide `a device as stated which can be used in either an upright position or on its side, in a manner to increase the versatility and maneuverability of the device and permit the cooking of a wide variety 'of different types of foods;
To so form the device that conventional broiler frames or food-holding devices of a similar nature may be suspended or supported in position upon the broiler in a manner to insure an even distribution of heat over the full area thereof;
To provide a novel means for facilitating the insertion of fuel and for improving combustion through the provision of a highly desirable flue effect;
To provide a device of the character stated, which is readily assembled and -disassembled and cleaned, and which when not in use, will occupy relatively small amount of space;
To so form the device that a plurality of surfaces thereof may be readily coated with reflective paper for the purpose of still further increasing the uniformity and eiciency of the heating action; and
To permit manufacture of the device entirely from relatively inexpensive, readily obtainable components.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel Afeatures of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:

Referring to the drawings in detail, designated generally at l0 is a portable charcoal broiler according to the present invention. This is shown in Figs. l and 5 supported upon a suitable supporting surface S.
The device includes a rectangular, one-piece, sheet metal base or bottom plate 12 integrally formed along opposite edges thereof with low, upwardly projecting flanges l. Projecting upwardly from base plate 12, medially Ibetween the opposite ends thereof, are confronting, identically but oppositely formed side plates 16, formed as wide, shallow channels having side walls 13' projecting toward each other, that is, the side walls 13 project inwardly from the adjacent'flanges f-14rwith the wide web portions of the side plates being in contact with the respective flanges 14. Screws 19 fixed to the bottom `of the side plates passing through bayonet slots 21 in the flanges ld serve detachably withy wing nuts 20 to fasten the base l2 tothe side plates 16.
Extending between the side plates 16, a short distance upwardly from the base plate l2, are confronting lower support bars 22, formed as angle members, said `ba-rs f2.2 being extended in parallel relation in a common plane parallel to the general plane of the base plate 12. VAt their opposite ends, bars 22 are welded or votherwise iixedly secured to the side walls of the respective side plates i6.
The lower support bars 22 constitute components of a fuel compartment designated 23. Saidy compartment comprises largely a grille structurefU-shaped in coniiguration and cross section. The grille structure is formed of Vexpanded metal and includes a bottom wall portion 24 and spaced side wall portions 26 (Fig. 4). The piece of expanded metal is supported, along op-posite sides of the bottom wall 24, upon the confronting lower support bars 22, and spot welds 2S are employed for iixedly connecting the expanded metal to said lower sup-port bars, as clearly shown both in Figs. 3 land 4.
The compartment 23 further includes, at the upper ends of the side walls 26, spaced upper supportbars 30, of angular configuration, secured by spot welds 32 (see Fig. 3)` to the top edgey portions of the respective side plates i6 adjacent the walls 26.
A top plate 34 of a configuration and sizeV matching those of the base plate 12, is removably mounted. o'n the top of the side plates 16. Plate 34 comprises a flat, single piece of sheet metall material formed along opposite sides thereof with depending anges 36 disposed in confronting relation to the respective flanges 14. Referring to Fig. 6, and also to Fig. 3, it' will be seen that the top plate 34 has a wide, transversely extending, rectangular opening 38, communicating with and' corresponding generally in configuration to the open top of the compartment 23'. Opening 38 extendings 'across substantially the full width of the top plate 325, andthe material of the top plate, at opposite sides of the opening 38, is bent upwardly to'provide elongated, upwardly convergent guide iianges 4G for a slidably movable lid or cover plate 42, one end of which isV bent upwardly to provide a handle 44.
As will be noted from Fig. 2, the lid 42' is` forced upwardly into engagement with the confronting' inner surfaces of the guide flanges 40 by the top portionsy 45 ofthe upper support bars 3l), said top portions being bent upwardly out of a common plane; so astolconve'rge in an upward direction. The lid is thus f'rictionalfl'yl held inl place between flanges 401a1ndtopv portions45',"but1of course, the lid can be slidably moved between opened and closed or partially closed positions, whenever desired.
`The topf plate 34 seats on the tops of the side plates 16 and is detachably supported thereon by means of pairs of L-shaped rods 46, adjacent the sides thereof. One leg 47 of each rod 46 is shorter than the other leg 48 and is offset laterally as indicated at 49 from the plane of the leg 48 so that the rod when in operative position has its offset portion 49 normally positioned close to the downwardly extending leg portion of the support bar 30 and its long leg 48 spaced downwardly from the top plate 34 as shown in Fig. 2. The short leg 47 is slidably mounted in a bearing member 47 formed adjacent each end of each angular support bar 30, and protrudes through an opening'37 in the adjacent flange 36 of the top plate 34. A protuberance or button 50 on the downwardly extending leg portion of the support bar 30 adjacent the offset portion 49 of each rod 46, and positioned in the path of sliding movement of said offset portion normally holds the adjacent rod 46 against displacement.
Thus, it may be considered that the broiler constituting the present invention is generally I-shaped, with a vertical portion being formed as a fuel-receiving compartment and being of foraminous formation at its bottom and its opposite sides, said fuel compartment extending transversely over the full width of the device, the device including horizontal, pan-like, top and bottom portions projecting beyond the opposite sides of the fuel compartment substantial distances in opposite directions so as to deiine spaces Within which food may be disposed, to be impinged upon and cooked by heat emanating from the fuel compartment.
Thus, in use, the device can be disposed in upright position as shown in Fig. 1, the device having the mentioned l-shape when so positioned. Charcoal or equivalent fuel would be deposited through the opening 38, and after being ignited, will produce heat that will travel laterally outwardly from the opposite, foraminous sides of the fuel compartment. The closure plate 42 can be left partly open, if desired, to provide a flue-like action, that is, air may be caused to travel upwardly through the charcoal through the opening 38 to increase combustion.
The broiler can be readily collapsed by merely pivoting the rods 46 upwardly toward the top plate 34 to swing the offset portions 49 thereof clear of the protuberances 50 when the short leg portions 47 thereof may be slid inwardly and the rods removed permitting the top plate 34 to be lifted olf of the side plates 16. Removal of the Wing nuts 20 from the screws 19 permits detachment of the base plate 12 from the side plates 16.
A conventional broiler frame or food holder generally designated at 52 may thus be suspended in vertically depending position from the long legs 48 of the respective rods 46 at a selected side of the device. Obviously, a plurality of broiler frames can be suspended from the rods, either at one side of or at both sides of thef fuel compartment. Further, the confronting inner surfaces of the top and bottom plates 34 and 12, respectively, may be coated with a reilective foil, or may themselves have reilective characteristics designed to increase the efliciency of the heating action of the device. The broiler frame 52 has the usual handles 54 projecting beyond one side of the portable charcoal broiler to permit manipulation of the food holder or holders. A drip pan 56 can be disposed below the holder, being supported upon the flanges 14 so as to be disposed out of contact with the at body portion of the base plate 12. This pan may retain and catch all the drippings from the food that is being broiled, so that said drippings are not lost.
It will be apparent that when the device is used as in Fig. 1, it can, with a relatively small amount of charcoal, cook simultaneously a large number of food items.
Referring to Fig. 5, the broiler is herein shown lying .on one side, so that the fuelcompartment 23 extendshorizontally rather than vertically. In these circumstances, the broiler has what might be appropriately termed an H-shape, with the horizontal-portion being defined by the fuel compartment and with the base and top plates constituting the vertical portions.
In these circumstances, the boiler frame 52 may be positioned in a horizontal plane, being supported upon the top edges of the plates 12, 34. This may be preferred in some circumstances, according to the particular food that is being cooked.
The broiler, as will be apparent, has considerable versatility, being adapted to permit quick broiling of a substantial quantity of fuel, though only a small amount of charcoal is being used. Further, the eciency of the heating action is measurably increased, due to the fact that the greatest part of the area of the walls of the fuel compartment is open in a direction to cause heat emanating from said compartment to impinge upon the food that is being cooked.
At the same time, the broiler is so designed as to be readily collapsed and capable of being cleaned with maximum ease, and in addition, the broiler has the desirable characteristic of being comparatively small, light, and designed for manufacture at a comparatively low cost.
While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
