STOVE.

Application filed December This invention relates to stoves, and particularly to stoves employing collapsible or knock down ovens adapted to be conveniently set up into functional position and as readily collapsed for ease in transportation. The particular novelty of this invention resides in providing a camp stove with oven consisting of a plurality of hinged or loose connections permanently fastened to the stove base as an unitary structure, the panels being adapted to form an oven or wind break, with a supporting shelf extending outwardly from the base, or they may be folded one upon the other to be received over the burner space of the case and secured there by one of the panels constituting a cover for the case when the ovenis .entirely collapsed.

The construction of the preferred embodiment of my invention illustrated in the accompanying drawings, will be clearly unthe following description, it being apparent that changes in form, proportidn and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

In drawings Fig. 1 is a perspective view of a stove equipped with accordance with my invention, the oven door being shown in open position.

s Fig. 2 is a detailed perspective view of the oven applied to the stove with the parts in position to be connected to form a rectangular oven and in the position which they will assume prior to forming'a combined wind break and shelf.

. Fig. 3 is a sectional viewthrough a portion of the back wall of the oven and through a portion of the top showing a special form of hinge.

Fig. 4 is a perspective view of the oven grate or shelf associated with the vertical walls of the oven when the oven is set up. Fig. 5 is a perspective view showing the oven swung back as a warming receptacle to receive food after it is cooked.

Fig. 6 is a perspective view showing the panels folded to provide a combined wind break and shelf and: a

immaterial what the construction of .the burner mechanism is, or how the fuel tank is supported, for supplying'fuel to the burner mechanism, so I am not attempting to illustrate that part of the stove in detail.

Referring now .to drawings by numerals of reference: 1 designates the bottom or case portion of the stove in which of course will be suitable burner mechanism having appropriate source of fuel supply. I have shown the cover or-lid 2 hinged to the case, the cover constituting one vertical wall of the oven when the oven is set up, in this particular instance, the back wall. The cover or lid 2 is provided with latches 3 and 4 to engage the slots in the case .1 when the parts of the stove are folded, that is, when the oven is in collapsible position. The latches are swingingly connected to the top edge of the lid 2 through the medium of the rod 5. Each latch is shown as having a loop 6 embracing the rod 5, each latch being provided with a flat portion 7 to lie against the case. The fiat portion 7 of each latch carries a pivoted latch member 8 so that when the lid or cover 2 is in cover serving position, that is when it is folded over on the base or burner case 1, the flat portion 7 will lie against the case. The toe 10 of member 8 to engage slot 9 may be slipped into the slot as may be clearly seen in Fig. 7.

' Since the latch member 8'is pivoted to the flat portion 7 of latch 3 and since the latch member 8 has a toe offset with respect. to fiat portion 7, it is obvious that the toe may spring against the wall of the case when member 8 is in latching position so that a frictional latching effect will be produced, this being effective to hold the latch in engagement with the case.

By referring to the drawings, it will be seen that the upper edge of the cover or top 2 is bent parallel with the main portion of the cover and then at a right angle to the main portion of the cover, the edges being bent or curled to provide an inset hinge 11 spacing inwardly from the upper edge of the cover 2. The hinge 11 is provided to support a top panel 12 substantially co-extensive with cover2. Hinged to the panel 12 is a front panel 13. The end panels may be secured to panel 13 by hinges, it being the purpose of this invention to securely fasten all of the panels one to the other so' that a they are non-detachable but cooperatively secured as a unit to the base structure. In the present instance I have shown one end panel 14 substantially the width of panel 13, fastened to the panel 13 by hinged connections at one end of the panel 13. T have also shown two panels 15. and 16 hinged to the end of panel 13. Each of the latter two panels being substantially one-half the.

width of panel 13, therefore one of the latter two panels, in this instance the panel 16 constitutes a door for the oven as w1ll be explained hereinafter.

The cover or panel 2, has flanges 17 and 18 which act as abutments or stays for panels 14, 15 and 16. The end panel 14 as shown is provided with means for'attachment to the panel 2, shown as fingers or projections 19 and 20, adapted to engagethe slots 21 and 22 in panel 2. The pro ect1ons 23 and24 on panel 15 engage the slots 25 and 26 in the opposite end of panel 2. The panel 2 has slots 27 and 28 to coincide with slots 29 and 30 in panel 13. course that there may be' as many slots 27 and 28, 29 and 30 as may be necessary to afford adjustment for the collapsible grate 31 shown in Fig. 3.

The grate is shown as consisting'of mem-. bers 32, 33, 34 and and the bars 36. Themember 33 is hinged. to the member 32 at at 38, so it will be seenthat members 32 and 33 constitute sectional cross bars at one end of the grate, while members 34 and 35 constitute a-sectional cross bar at the other end of the grate. There may be, as many longitudinal bars 36 as are necessary to provide the proper grate. These bars 36 are all p1voted to the grate members, 32, 33, 34 and 35 and since member 32 is pivoted to member 33 and member 34 is pivoted to member 35 and all longitudinal bars are pivoted to the cross bars, it ,will be seen that the grate or shelf may be collapsed or folded within a small compass to be conveniently received within the hollow base or case structure 1.

In the present embodiment of my invention, I have shown ends of bars 33 and 35 folded over at 39 and 40 and notched at 41 and 42 so that the bars may latch in the openings .29 and 30 to prevent accidental disengagement of the grate when the ends of the bars 32, 33, 34 and 35 engage the openings 27, 28, 29 and 30. The panel 15, while hinged to the front wall'or panel 13, maybe made rigid with panel 2 by inserting the fingers 23 and 24 into the openings 25 and 26. The panel 14 is made rigid with panel 2 by inserting the fingers 19 and 20 in the openings 21 and 22. The panel door hinged to the panel 13 and it is provided with 'a' latch 43, having a finger 44 to eiigage slit 45 in panel2 to hold the. door 0 osed.

vided swinging which may fold "when the stove is to be transported. The

It is obvious of 16 constitutes a and it is desired to It is desirable to support the stove referred to a suitable distance above the ground because the bottom of the case is generally perforated to supply air to the burner structure and because the stove may be more conveniently used if it is supported oil of the ground. Therefore I have proloop base legs 46 and 7 over the ends of the case construction of the legs, in so far as this present invention is concerned, is immaterial. The detail of construction of the burner mechanism constitutes no part of my present invention, so I deem it unnecessary to more than merely indicate the presence of the burner mechanism in the case.

The latches 3 and 4 serve a dual purpose in that they not'only hold panel 2 (which in the present case constitutes the cover) fast to case 1, but they can be swung back to the position shown in Fig. 5 to constitute supporting legs for the oven when the oven is tilted back to expose the burner of the stove and assume a position where it can be \utilized as a warming oven or when occupy- The cover or lid, in the present instance,

v thepanel 2, may be made of slightly 37. The member 34 is hinged to member 35 h eavier material thanthe panels 13, 14, 1 5 and 16 since it is the enclosing panel and since it receives the panels 13, 14, 15 and 16, thus not necessarily an essential part of my invention however.

If the parts are in 1, that is setup and it is desired to collapse theoven, the grate should first be removed, the fingers 19, 20, 23 and 24 may then be disengaged from their slots. The panel 12 may now be folded into the space confined by the flanges 17 and 18. The panel 13 may be folded back on; panel 12 then the panels 14, 15, and 16 can be folded down onto the panel 13, the grate having been on the hinged burner case frame 48 with position shown in Fig.

constituting a baking oven,

previously collapsed and stored tank 49 folded in under the top 48, the legs 6 vided with a hinged tubular connection with a pipe which communicates with the generator of ,the burner. Such a connection is shown in U. S. patent to Win. C. Coleman,
