7 My invention relates to and has for its purpose the provision of a stove particularly adapted, although not necessarily for the use of campers in cooking and heating, and embodying sections capable of being either assembled to form the stove or disassembled and so associatedwith each other as to form a compact parcel for transportation, all with theutmost case and dispatch.

It is a further purpose of my invention to provide a knockdown stove having a minimum number of parts and characterized by its structural simplicity, durability and inexpensiveness of manufacture.

I will describe only oneform of knockdown stove embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawing,

Fig. 1 is a vertical longitudinal sectional view of one form of knockdown stove embodying my invention, set up for use.

Fig. 2 is a front end elevation of the stove,

Fig. 3 is a horizontal sectional view of the stove taken on the line 3-3 of Fig. 1;

Fig. 4 is a perspective view illustrating disassembled, various sections comprising the stove, and

Fig. 5 is a perspective view illustrating the manner in which the parts of the stove when disassembled, are adapted to be associated with each other to form a compact parcel for transportation.

Referring specifically to the drawings in which similar reference characters designate similar .parts in each of the several views, my invention in its present embodiment comprises top and bottom sections lO and 11 of rectangular outline preferably constructed of sheet metal of suitable gage and provided around their marginal edges with depending and upstanding flanges 1.2 and 13 respectively. Other sections 14, 15, 16 and 17 also preferably formed of sheet metal are provided, and co-operate to form the side walls of the stove when the sections are assembled.

The sections 14 and constitute side sections while the sections 16 and 17 constitute end sections, the sections 14 and 15 being received within the flanges 12 and 13 of the top and bottom sections so as to be interposed between and span the latter along their sides, while the sections 16 and 17 are also received within the flanges 12 and 13 of the top and bottom sections so as to be interposed between and span the latter along their ends, all as clearly shown in Fig. 3. The confronting vertical edges of the side sections 14 and 15 and the end sections 16 and 17 are provided respectively with flanges 18 and 19 which overlapwhen the {sections are assem bled as shown in Fig. 3, to close the joints between the side andend sections. The flanges 12 and '13 broadly constitute means for confining the side and end sections against outward displacement from the top and bottom sections.

The top and bottom sections are provided adjacent the corners thereof with registering openings 20 and 21 respectively through which are adapted to be; extended, tie members22 having heads 23 adapted to abut the top section 10. The tie members are provided with transverse openings 24 through which are adapted to be extended, pins 25, one for each two tie members so that two pins are provided. As the tie members extend within and in close proximity to the side and end sections when the latter are assembled with the top and bottom sections as shown in Figs. 1 and 3, the tie members broadly constitutea means for confining the side and end sections against inward displacement from the top and bottom sections. Furthermore when the sections are assembled as shown in the above mentioned figures, the .pins 25 co-act with the heads 23 of the tie members to" maintain the sections assembled by the tie members for co-operation of the sections in forming a closed receptacle, as the heads abut the outer side of the top section 10 and the pins 25 abut the bottom section 11.

The tie members 22 are preferably of sufficient length to project below the bottom sec controlled by a hinged door 27 having a pivoted latch 28 adapted to engage a keeper 29 on the end section to maintain the door closed, while the top section 10 is preferably provided adjacent its end remote from the end section 16 with a draft or chimney opening 29 surrounded by a collar 30 to which a suitable stack (not shown) is adapted to be connected. hen the stove is set up for use, thetop of the top section 10 provides a convenient cooking surface on which foods or vessels can be placed.

It will be clear that to assemble the sections. it is only necessary to extend the tie members 22 through the openings 20 of the top section 10, after which the latter is inverted and placed on a support so that the tie members project upward. The sections 1%, 15, 16 and 17 are then placed vertically in the top section between its flange 12 and the tie members 22. after which the projecting upper ends of the tie members are extended through the openings 21 of the bottom section 11. The pins 25 are then each extended through the openings 24 of the front and rear tie members so that all the sections will be held assembled bv the tie members and will co-operate to form the stove.

To disassemble the sections, it is only necessary to reverse the above described operations; and when the sections are disassembled. they, with the tie members and pins, can be arranged to form a compact parcel for transportation. In this instance, the side sections 14 and 15 which are of slightly different lengths are nested one within the other and placed. in the bottom section 11 which forms the bodv of a receptacle. The end sections 16 and 17 which are also of slightly different lengths are nested one within the other and placed transversely in the bottom section, after which the tie members 22 and pins 25 are placed in the latter all as clearly shown in Fig. 5. Finally the top section 10 which is slightly larger in area than the bottom section is placed over the latter to form a cover. Thus a fiat and compact parcel is formed of all the parts comprising the stove so that the latter can be readily carried about.

Although I have herein shown and described only one form of knockdown stove embodying my invention, it is to be understood that various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scope of the appended claims.

I claim:

1. A knockdown stove comprising a top section. a bottom section, other sections interposed between the top and bottom sections to space the latter sections and form the side walls of the stove, flanges on the top and bottom sections for confining said other sections against outward displacement, tie members extending through the top and bottom sections within and in proximity to said other sections to prevent inward displacement of the latter sections, heads on the tie members, and removable pins in the tie members 00- acting with the heads to maintain the sections assembled by the tie members.

2. A knockdown stove comprising rectangular shaped top and bottom sections having depending and upstanding flanges respectively at their marginal edges, side and end sections interposed between and spanning the top and bottom sections to form the side walls of the stove, the confronting edges of the side and end sections having overlapping flanges to close the joints between the side and end sections, the top and bottom sections having registering openings therein adjacent the corners thereof, headed tie members extending through the openings and co-operating with said flanges to confine the side and end sections against inward and outward displacement, and means co-acting with the heads of the tie members to maintain the sections assembled by the tie members.
