PORTABLE COOK STOVE Filed Oct. 31, 1960 2 Sheets-Sheet 2 INVENTOR. IEETER 5. HARDY WW ATTDRNEY rates The present invention relates to a portable cook stove, and particularly a charcoal or briquet burning grill or broiler type stove of compact construction, attractive appearance, and efficient operation, suitable for outdoor picnic or indoor table use.
An object of the invention is to provide a stove in which the major components maybe in the form of lightweight aluminum castings, and in which the fuel containing grate may be in the form of an iron casting, the various components being so related that the aluminum components are etlectually protected from direct contact with the fuel. Another object is to provide a stove in which the fuel containing grate has minimum points of contact with the external body of the stove and is surrounded by an air space, to the end that there is a minimum degree of heat conduction between the grate and the stove body with little or no dissipation of heat due to conduction, with the result that the stove body remains comparatively cool while the grate effectually retains its heat. A further object is to provide a fuel container having a primer receptacle for receiving a suitable priming fluid for quickly initiating the ignition of the charcoal, briquets or the like.
Another object is to provide improved damper means whereby the supply of air to the fuel containing grate may be effectually controlled and evenly disnibuted.
A further object is to provide a stove having improved means for adjusting the height of the food supporting grill, pan or the like. Another object is to provide a stove in which one of the food containing components constitutes in one position of adjustment a substantially air-tight closure which in cooperation with the damper means in the closed relation of the latter will elfect the extinguishing of the fuel, thus enabling partially consumed fuel to be utilized upon a subsequent occasion.

FIG. 15 is a bottom plan view thereof.
Referring to the drawings the portable stove according to the invention comprises a base part 10, shown in its separated relation in FIGS. 11 and 12, preferably formed of cast ahuninurn and consisting of a circular ash receiving well 11 provided at its upper edge with an annular ledge 12 and a vertical annular wall 13 surrounding the ledge. The wall 13 is provided along its front and rear portions with a series of air inlet openings 14 and at its respective end portions with a pair of slots 15 and 16 which are respectively offset in opposite directions relative to the longitudinal center line of the base, for a purpose hereinafter more fully pointed out. A plurality of suit-ably positioned supporting legs 17 extend downwardly from the ledge 12 below the lower surface of the ash receiving well 11, and a pair of handle extensions 1818 extend outwardly from the opposite ends of the base part and are respectively provided with hand grips 19-19 for the convenient lifting and carrying of the stove.
Centrally of the ash receiving well 11 there is provided a raised boss 20 having a center hole 21 for receiving an assembly screw, and which opens to a pocket 22 at the lower side of the boss for receiving an assembly nut upon the screw, as will hereinafter more fully appear.
The damper part 23, shown in separated relation in FIGS. 13-15, is preferably formed of cast aluminum and comprises a circular wall 24 adapted to fit within the wall 13 of the base part in resting relation upon the ledge 12 for free rotation relatively thereto, and provided with a series of openings 25 which in one position of adjustment register with the openings 14 of the wall 13 of the base member to provide a series of air passages, and in the other position of adjustment are disposed between the openings 14 so that the wall 24 of the damper closes the openings 14. In intermediate positions of adjustment the degree of opening of the air passages may be varied. At the upper edge of the wall 24 there is provided an inwardly and downwardly inclined annular flange 2-6 which constitutes a baflle to direct incoming air from the air passages downwardly mid inwardly toward the central area beneath the fuel containing grate, as is clear from FIG. 4.
At diametrically opposite sides of the wall 24- there are provided a pair of knobs 27-27 which are respectively disposed in the slots 15 and 16 of the base part 10 and are adapted in the closed position of the damper, as seen in FIGS. 3, 4 and 6, to abut one end wall of the respective slots 15 and 16 and in the open position of the damper, as seen in FIGS. 1 and 5, to abut the other end wall of the respective slots. It will be observed that in the closed position of the damper part the knobs are disposed along the diametric longitudinal center line. of the base which extends centrally through the handles 19. Thus the handles 19 are so disposed with relation to the knobs '27 that the damper part may be conveniently operated to its open or closed positions by gripping one of the handles 19 and pressing the knob 27 in one or the other direction with a finger of the hand gripping the handler ing and comprises a bowl-like downwardly tapered side wall 29 provided at its upper edge with an annular ledge 30 and a vertically extending annular rim wall 31 surrounding the ledge. The bottom of the body member is in the form of an open spider structure comprising radial arms 32 extending in downwardly and inwardly convergent relation from an annular external bead 33, and joined at their inner ends to a circular cup-shaped hub portion 34 provided centrally with a bearing boss 35 having a vertically disposed threaded countersink hole 36 centrally therethrough, in which is screwed a screw stud 37 projecting downwardly from the hub. The hub is preferably provided with radial reinforcing ribs 38.
As shown in FIG. 4 the annular bead 33 fits within the upper edge of the side wall 13 of the base part 10, and is opposed to the upper edge of the damper part 23 with suflicient clearance to permit the free rotation of the damper part within the base part. The body part is rigidly secured to the base part by engaging the screw stud 37 through the center hole 21 of the base part and a plurality, preferably four, of equally spaced lugs 39 having their upper sides in a horizontal plane spaced below the ledge 3% for the purpose of providing supports for the fuel grate part 40, shown in separated relation in FIGS. 9 and 10.
The grate part 40 is preferably formed of cast iron and comprises a curved side wall 41 and a downwardly and inwardly inclined base wall 42 extending to a central cup portion 43, the rim of which extends slightly above the upper surface of the base wall 42 and the bottom of which extends slightly below the base wall. This cup is for the purpose of containing a primer fluid for facilitating the quick ignition of charcoal or briquet fuel placed in the grate. The base wall 42. is provided with a plurality of suitably arranged holes 44 for evenly distributing combustion air entering the base part through the damper means to the fuel.
At the upper edge of the sidewall 41 there is provided an annular flange 45 which seats upon the lugs 39,
these being the only points of contact between the grate part 40 and the body part 28, so that the contacting areas are reduced to a minimum and thus there is a minimum of heat conduction between theseparts. Additionally there is a substantially large annular air space between the wall 41 of the grate part and the wall 29 of the body part which also serves to prevent dissipation of heat from the grate part.
In order to facilitate removal and replacement of the grate part 40 there is provided in the rim a pocket 46 having an upper wall 47 provided with a slot 49 for interlocking by the lip 50 of a lifter 51.
Upon the inner side of the rim wall 31 of the body part there is provided a plurality, preferably four, of equally spaced ramp formations 52 which extend in upwardly inclined relation from the annular ledge surface 30 and which terminate at their upper ends in positioning notches 53, these ramp formations being for the purpose of elevating the food supporting part from a lower position resting upon the ledge 30 to an upper position resting the notches 53, as will presently more fully appear.
The food supporting grill part 54, FIGS. 14, is preferably formed of cast aluminum and comprises an annular trough 55 surrounding a grill structure consisting of four channel bars 56 disposed at right angles to each other along the diametric radial lines of the circular space surrounded by the trough 55, these bars being slightly inclined downwardly from their central meeting point to the trough so thatjuices of a steak, for instance, supported upon the grill will flow along these channel bars to the trough. In each of the four segments between the channel bars 56 there is provided a radial diagonally extending bar 57 to which there are connected the corners of a series of right angle channel bars 58, the legs of which extend in parallel spaced relation to and in the same inclined plane with respect to the channel bars 56 forming two sides of the segment. In similar manner to the channel bars 56 the channel bars 58 direct juices from the steak or the like supported upon the grill to the trough 55.
At diametrically opposite points of the outer wall of the trough 55 there are provided pouring spouts 5959, and at a point centrally between these pouring spouts there is provided a projection 60 having a slot 61 for receiving the lip 50 of the lifter 51,, in similar manner to the engagement of the lifter with the grate part 40 as seen in FIG. 9, for the purpose of removing the grill or adjusting its height position with respect to the body part 28. For this purpose the trough 55 is provided at its under side with a plurality of downwardly projecting legs 62 which fit within the wall 31 of the body part and in the lower position of the grill rest upon the ledge 3th In the raised position of the grill, as seen in FIGS. l-4, the legs 62 are elevated through movement along the ramp formations 52 into engagement with the notches 53. In either position there is an air space between the trough and the rim 31. The height adjustment of the grill part permits the steak or the like supported thereon to be placed at any desired distance from the fuel, the inclinations of the ramp formations 52 being at a sufiiciently low angle to support the legs thereon with stability at any desired position between the ledge 30 and the notches 53.
A food containing pan part 63, FIGS. 5 and 6, comprises an annular downwardly tapered convergent wall 64, a closed bottom 65, and an annular rim 66 at the upper edge of the wall 64, which in the closed position of the pan part, as seen in FIG. 6, rests upon the rim 31 of the body part. Upon the outer side of the wall 64 there are provided a plurality of lugs 67 having vertical outer edges adapted to fit within the rim 31 of the body part and horizontal lower edges adapted by movement along the elevated ramp formations 52 to seat in the notches 53 in the raised position of the pan part, as seen in FIG. 5. A projection 68 having a slot 69 is provided upon the rim 66 for engagement by the lip 50 of the lifter 51 for the purpose of manipulating the pan part.
It will be observed that the lugs 67 position the pan part in centralized relation with respect to the rim 31 of the body part in any position of adjustment of the pan part and that the height of these lugs is such, as seen in FIG. 6, that in the lowered or closed position of the pan part they are slightly free of engagement with the ledge 30, so that the rim 66 will rest directly upon the upper edge of the rim 31 to thus exclude air from entering between the pan part and the body part. Thus by closing the damper with the pan part in its lower position, as seen in FIG. 6, all air is excluded from the fuel causing it to he quickly extinguished and enabling partially burned fuel to be utilized upon a subsequent occasion.
