' "This invention relates to stoves and refers more particularly toa portable stove suitable for indoor and outdoor broiling, barbecuing and sirnilar cooking operations.

The principal object of our invention is to provide for sportsmen, campers, or for use in outdoor cooking or indoorcooking over a hearth, aportable stove unit suitable for 'broiling, barbe'c uing} smoking, baking and similar purposes, which possesses the desirable advantage of simplicity'of operation combined with well regulated heat control: To this'end an important feature "of our invention resides in the provision in a portable stove of selective levels over the heating unit to 'which thefood may be easily moved during the cooking-process. In this connection it-is an'additional feature of the invention that the heating unit comprise a fire box or trough having displaceable ends whereby-the fuel bed may be'concentrated,"dispersed or changed in sizeasdesired." V 1 "i {Another object of our invention i s .'to provide *for the purpose describeda portable-knock-down stove which maybe easily moved i n .either the assembled or disassembled condition and used as-an integral, self-sustaining unit, or separately, in connection with an interchangeable hood or oven. Therefore, a salient feature of theinvenvtion resides in the assembly of the stove as a combination of demountable, separate heating and cooking units on a wheeled carriage. r

a An additional obiect at our invention is'to provide in 'a portable stoveof the character described a unit-which is highly versatile; economical to produce, attractive in appearance andfeasily packed for storage.

Other and further-obiectsof our-invention, to-

gether with the features of novelty, will appear Iinth'e course of thefollowing description. j 1:."In .the accom-pany-ing drawings, which form a part of the instant' specification and are to'be read in conjunction therewith, and in which like reference numeralsare employed to identify like parts of the various'views: 4 ."Figll is a perspective view of aportable stove suitable for. barbecuing, broiling and similar purposes, with a fragmentary portion of the'frame cut away to reveal the socket assembly'features, Fig. 2 is ahorizontal crosssectiontaken along the lines 2.2 of Fig.1 inthe direction of the arrows,- 1 i r Fig; 3 is a perspective view of'a bafiie designed for use in the fire box of the stove f Fig. 4 is a vertical cross section'taken along the .lines, 4.4, of Fig.1 in the-direction -of the arrows,

Application February 13, 1950, ,seriai'No. 143,938 '1 Claim. (01. 126'25) Fig. 5 is a perspective view of a spit for use in the grill box of the'stove.

Fig. 6 is a perspective view of 'a modification of the invention wherein an oven replaces thehood of the modification shown in Fig. 1, with a corner portion of the grill box cut away to reveal assembly features at that point, i V n Fig. '7 is a vertical cross section taken along the lines 1-1 of Fig. 6 in the direction'of thearrows,

Fig. 8 is a horizontal cross section taken along the lines 8-3 of Fig. '7 in the direction of the arrows.

Referring more particularly to the drawings, in the embodiment of our invention shown in Fig. 1 the reference numeral 9 denotes a wheeled carriage having vertically extended :legs It, in the upper ends of which are formed sockets II. Joining the legs at the sockets and near the bottom are pairs of parallel angle bars 12 and 12a respectively, and disposed in the top of the framework thus formed is a receptacle or ash tray [3 having its out-turned upper edges resting upon the horizontal surface of the bars 12. A looped hand bar 14, demountably attached by means of the wing nuts Ila to the sockets at one end of the frame, as indicated, and a single pair of wheels 15, attached to the lower ends of the legs at the opposite end of the unit, provide a means for moving the carriage from placeto place as desired.

In the sockets ll reside grill support bars"? in the upper ends of which are located pins 16a. Resting upon the upper ends of these bars, with "holes therein'in register with the pins lfia, are

the out-turned upper edges of an open-end, open-top trough forming a firebox I! having its downwardly converging side ,walls and floor perforated by a plurality of draft holes, Ho, The open ends of the firebox are'closed by displaceable wedge-shaped bafiles 18, indicated in Fig'. 3, which may be moved inwardly along the floor of the box to change the size of the fuel bed or to concentrate the source of heat at any desired point. A convenient utility shelf I9 is located on the outside of the wheeled end of the carriage, being joined to the lower ends of the supporting rods I6 below the end of the firebox as indicated.

Resting upon the upper edges ,ofjthe firebox, with its in-turned lower edgeshaving holes in register Withthe pins lfia of the bars I6, is an of the end walls 2| are three'laterally spaced, vertically elongated slots 22 having in one side thereof longitudinally spaced, downwardly inclined notches 23, and over the notches of the center slot are located pins 23a whose function will be described in more detail presently. Easy access to the grill and fire boxes is provided by means of a hinged downwardly opening door 24 located in one of the side walls 20.

In connection with the grill box, there is provided with the stove a grill 25, or wire mesh or other "suit-able'material, having supports :26 to which ra'redtt'ached removable handles 21. When the grill is placed in the grill box the supports 26 reside in the oppositely disposed notches 23 lot the outer slots 22), as indicated in Figs. Land with the grill handles 21 aifixed to the ends .01 the supports on the outside of the box as that the pins 23a over-the notches willeengage the holes in the plate v.25 preventing turning of ,the Spit when .the plate is .flush against the end wall of .the box.

.As can best-beappreciated from Fig. 4, the spit can be used alone or in conjunction with theggrill, and .-both may be adjusted by means of the riotchesin various positions over the firebox, proa greater orless intense .cooking .heat as. ;desired. this arrangement, however, it .can

ibeseen that an additional position, .or fourth .-level of .heat, is provided .for :the .grill :when I it is used without thespitsince the grill .supports may thenbe rested in any-of the threeavailable rnotohesras well asdropped to the lower ends of ..the.-slots directlyover the firebox.

For ithe'purposeof retaining theheat .and protecting the food being cooked, in the embodiment of our invention -,presented .in Fig. 1 there rests upon the top -of thegrill box ademountable hood 30 having its lower edges :grooved to receive the upper edges of :the grill vbox. However, the stove is operable -withoutwthe hood, and it is contemplated that a hot plate, additional -grillboxyoi :other auxiliary attachments may .be employed with .the

Referring to Fig. 5, there is also provided .aspit:

cated, the water pan prevents direct contact of the cooking food with the radiant heat of the fire unit, deflects the smoke and heat around the grill into the oven, and enables baking with the resultant water vapor providing the proper humidity necessary to cause meats to retain their juices.

Whether the stove is being used for roasting, broiling, or baking, the desired heat for the oper- -ationmay beattainedmreveml WAYS. It is possible, "by'moving the bellies II toward the center of the firebox, to change the size of the heat source or to concentrate the heat at any desired point. ,Lowering or raisin the spit or grill in the notches makes it possible to uniformly sear meatin miintense heat at a low level or to slowly simmer it with less heat at a higher level. Reguoven demountablyattached to .the grill box by means .of inset grooves along the bottom edges which areadapted to receive the upper: edges .of 'theagrlll box. The end .walls .32, -top 33, andside wall 34 opposite-the oven doors .are lined with .asbestosorother suitableinsulatingsmaterialover .whichis .-fastened a thin metal innerlining -'35.
