This invention relates portable stove.

An object of the invention is the construction of a simple and efiicient portable stove to a combination which is admirably adapted for use by college A still further object of my invention is theconstruction of a portable stove comprising two hinged casings, each casing being constructed for supporting a number of cooking units, and one of the casings provided with a holding device for supporting canned fuel when the operator desires to heat one or more of the units by a flame instead of utilizin electricity.

ith the foregoing and other objects in view, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated -in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

I Figure 12 is an enlarged perspective view of one of the folding handle devices, while Figure 13 is partly a longitudinal section and partly a side elevation of the same.

Fig. 14 is an enlarged sectional view taken on line 14-14, Figure 1.

Figure 15 is a perspective view of the bottom of the holding device for canned fuel.

Referring to the drawings by numerals, 1, 1 designates two casings that are substantially the same in structure. These casings 1 are connected together by two hinges 2. These casings 1 are secured in a closed or folded position (Fig. 1) by means of a latch device 3 (Fig. 14). This latch device 3 comprises a hasp 4 that is hingedly connected to one of the casings at 5. A staple 6 is secured to the other casing. The hasp 4 is provided with an elongatedslot 7, which is enlarged at 8 to receive the staple 6. A sliding plate 9 is in the elongated slot 7, and a top plate 10 is on top of the hasp 4 with a screw 11 extending through said plates 9 and 10 and into nut 12, securing the parts together. When the hasp 4 is over the staple 6 and the top plate 10 is slid forwardly, the outer end of plate 10 enters the staple 6, securing the hasp in place for holding the two casings against accidental openlng.

For moving or carrying the apparatus, I provide a handle 13 for each casing 1. The handles are pivotally mounted in sets of brackets 14. The operator can grasp both handles at once, and easily convey the apparatus to the desired position.

Each casing 1 is of similar construction and therefore, I only specificall describe one. The casing is provided wit two parmeans of rivets 28.

allel supporting plates 15 (Fig. Each late is provided near its center with a orizontal groove 16 in which the flanged ed e of a pan cooking unit 17 is positioned ig. 3). The plate 15 is provided on its lower edge with preferably two horizontal lugs 18 through which extends the screws or bolts 19 (Fig. 4). The heads 20 of bolts 19 are on the outside of the bottom of the casing, constituting supports, because said heads will engage the surface of the table or the like upon which the apparatus is placed, thereby not requiring the whole bottom of each casing to engage the support, or table. The heads 20 may be covered with any ordinary means, such as rubber (not shown) to keep the heads from injuring or scratching the support. The upper edge of the plate 15 is 1 rovided with preferably two flanges 21.

ach flange is provided with an inwardly extending lug 22. Lug 22 is provided with depending flanges 23 on three sides. A nut 24 (Fig. 7) is placed between flanges 23 of lug 22 and a screw 25 extends through the horizontal collar 26 and through lug 22 into said nut 24 securing the parts together. The flanges 23 keep the nut from turning and, therefore, constitute a nut lock therefor. On the outer face of each plate 15 is a horizontal bracket 27, which is fastened to the plate by The two brackets of each casing are in horizontal alignment, to support the heating cooking unit 29 (Fig. 3).

The heating cooking unit 29 is provided on its rearend with an ordinary electric plug attachment 30 (dotted lines Fig. 6), which plug attachment registers with a rear sliding door 31. To insert the heating cooking unit 29, the pan-like cooking unit 17 is removed, and then the rear end of the unit 29 is placed down in the large opening 32 of collar plate 26 and then the heating unit is'brought to a horizontal position upon the supporting brackets 27. Then to secure the heating unit 29 in place, I provide two catch devices 33 (Fig. 8). At opposite sides of the heatin unit 29, I form elongated apertures 34. g sliding plate 35 is fastened to the inner face of collar plate 26 by means of screw 36, This screw 36 is slidably mounted inelongated aperture 37. Parallel with sliding plate 35 is a plate 38; plate 38 is fixedly secured to the inner face of collar plate 26, and this plate 38 keeps the sliding plate 35 from turning, or in true alignment with the elongated aperture 34 in the side of the heating unit 29. Therefore, it will be seen that by shoving screw 36 forward, the outer end of sliding plate 35 will enter the aperture 34,1ocking the heating unit 29 in positlon.

' stance The electrical heating unit of each casing 1 is similarly constructed. In each heating unit, I place a cooking unit 39 (Fig. 3) of any known structure such as a waflle iron or a toaster. These cooking units, as well as the pan unit 17 are placed within the casing through the main opening 40; this main opening is known as the front opening. Each of these openings may be closed by the front sliding door 41 (Fig. 11). The structure of the front doors 41 and therear doors 3,1 are similar. Each door comprises a curved body having an outwardly extending knob 42 that the operator grasps for manipulating the door. At the rear or other end of the body is cut or stamped out a lug 43. This bent out lug 43 acts asa spacer or guide to prevent the door from binding as it. is slid back and forth within the casing. On the bottom of the casing is formed an annular groove 44 in which the bottom of each door slides; the outer end of lug 43 hearing always against the inner face of the side of the casing 1. The upper end of each door (Fig. 4) is free to slide behind the plate 15 because the ends of each plate 15 do not extend to the inner face of the casing 1 (Fig. 6). Therefore, it will be seen that I have two sliding front doors 41 and two rear sliding doors 31.

. When it is not desired to use electricity as the heating means, then the heating units 29 are removed, as well as the pans and what is known as canned fuel is employed, which is sold on the market under the name for in- Sterno. To accommodate this canned fuel being used in my casing, each is provided on the inner face of the bottom with parallel upstanding tracks 45. Upstanding lugs 46 are fastened to the bottom and engage opposite sides of each track for the purpose hereinafter described. The canned fuel holding device 47 (Fig. 15) comprises a horizontal plate 48 that is bent over along its longitudinal edges 49 forming reinforced edges. The ends of plate 48 are folded to form track grooves 50, in which the tracks are 051- tioned. When the holding device 47 has een slid on the tracks'to the center of the casing, riding over and being positioned between the two sets of retaining lugs of each track,

'said holding device can not be accidentall displaced. Sliding jaws 51 are provide each jaw having a horizontal base 52, through which extend screws 53 and 54. These screws 53 and 54 extend through elongated slots 55 in plate 48. To each screw 54 is'fastened the outer end of a coil spring 56 by means of nuts 57. A plate 58 has its ends under the folded over portions or flanges 49 (Fig. 15) and the center ofthe plate is formed into a socket 59, in which the outer end of coil spring 56 is reion III

movably seated. As the jaws 51 are spread apart for accommodating different size canned fuel, greater compression is caused on the coil springs 56, which results in the can being held securely between the'jaws. This I have found to be true from actual experience with a full size working model. In fact, this whole apparatus has been reduced to practice, and has been found in every particular to be highly efiicient. When the holding device 47 is not in use, it can be placed in one of the pans, and the pan unit inserted into the casing for storage purpose.

The entire bottom of each casing is covered by a sheet 60 of asbestos or like non-heat conducting material, whereby, in use, the apparatus can not give ofi sufficient heat to injure any furniture upon which it may be placed.

Each cooking unit is provided with at least one folding handle device. This handle device 61 (Figs. 12 and 13) comprises a plate 62 fixedly secured to the outer side of the cookin g unit 17 or 39 Extending outwardly from plate 62 is a post 63. The outer end of post 63 is flattened and terminates in a straight edge 64 and an outwardly extending spur 65. A yoke 66 straddles the outer end of post 63 and is pivotally mounted on the post by means of screw'67. Yoke 66 has a screw 68 extending therethrough and into the handle 69. The head of screw 68 (Fig. 13) is adapted to receive the spur in the groove 70, whereby this positioning prevents any further pivotal movement of handle 69 upon the post and also braces and stabilizes the entire structure by the spur 65 acting as an additional fastening means etween the post and the handle while the ban leis in its extended or open position, prior .to closing against the body of the cooking unit. When all of the cooking units are in the casing, the handles 69 are folded inwardly, against the cooking unit, whereupon the main doors 41 can he slid to a closed position. as shown in Figure 1.

It will be seen that in my apparatus, everything is concealed, suggesting a stove; when the sections are folded together as shown in Figure 1. When thus folded together, the apparatus has the appearance of a carry all hat box, attractive in color and design. But when opened, it is seen to be a complete cooking outfit for both electric and canned fuel, ever ready for quick service.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
