2 Claims. (Cl. 126-9) This invention relates to a camp stove construction and has for an object to provide a stove that is transportable in compact knock-down form and which sets up to provide an efiicient and safe device that is practical to burn charcoal or camp site materials such as wood, pine cones, etc.

Another object of the invention is to provide a camp stove in' which the fire box is of large capacity, when erected, and yet may be compactly arranged to house all of the stove elements, such as support legs, stack, warming shelves, etc.

A stillfurther object of the invention is to provide a camp stove in which the fire box comprises similar halves or sections that are adapted to be nested one within the other for compactness during transportation and the hollow formed by such nested halves housing the remaining components of the stove.

The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working .position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes, one embodiment of the present invention, which is given by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Fig. 1 is a perspective view of a camp stove in erected condition, showing the present invention.

Fig. 2 is an enlarged vertical and fragmentary sectiona1 view as taken on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary sectional view as taken on line 3-3 of Fig. 1. i

Fig. 4 is a rear end elevational view of said stove in knock-down condition.

Fig. 5 is a similar view of the opposite end.

Fig. 6 is a side elevational view of the stove as in Figs. 4 and 5.

Fig. 7 is an enlarged and broken longitudinal sectional view as taken on line 7--7 of Fig. 4.

Fig. 8 is a similarly enlarged cross-sectional view as taken on line 8-8 of Fig. 6 with certain parts removed.

The camp stove that is iluustrated comprises, generally, a fire box 10 provided with a flue o1- stack 11 and supported on a set of legs 12, and a pair of warming shelves 13 attached to the opposite sides of the fire box. The present stove structure includes a closure member 14 used in the knock-down arrangement of the parts to unify the compactly arranged parts for ready handling, storage, and transportation.

The fire box, in this instance, comprises two similar halves l5 and 16, respectively upper and lower, the same being preferably formed of sheet steel and so proportioned that the lower half 16 is adapted to fit into the Fee upper half 15, as illustrated in Figs. 7 and 8. Thus, while both halves 15 and 16 are rectilinear in form, the upper half 15 is somewhat longer, wider and higher than the lower half 16.

The upper half 15 of the fire box is formed to have a top 17, sides 18, and a back 19, that comprise immovable walls, and a front wall or door 20 that is connected to the forward end of the top 17 by a hinge 21. Thus, said front wall 20 is capable of being swung open on its hinge to give access to the interior of the upper part of the fire box. An adjustable draft control 22 is provided on the door 20 and may be adjusted, as desired, while the door remains closed. The lower edges of the side walls 18 are provided with outturned flanges 23, and the lower edge of the back wall 19 is provided with a similar flange 24.

The lower half 16 of said fire box is formed to have a bottom 17a, sides 25, and a back 26, that comprise immovable walls, and a front wall or door 27 that is connected to the'forward end of the bottom 17a by a hinge 28. Said front wall 27 is capable of being swung open on its hinge to give access to the interior of the lower part of the fire box. Thus, it will be seen that the two doors 20 and 27, when open, provide a fully open front on the fire box. An adjustable draft control 29 is provided on door 27, the same being similar to draft control 22, and is independently operable. The upper edges of the side walls 25 are provided with outturned flanges 30 similar to and matching the flanges 23 of the upper half of the fire box, and the upper edge of the back wall 26 is provided with a flange 31 that is wider than flange '24 and matches therewith, as shown in Fig. 3.

Bolts or the like 32 are used to connect the fire box halves, in the manner shown in Fig. 1, so that top 17 constitutes the stove top. In practice, it is preferred to reinforce both the top 17 and bottom 17a with transverse members 33 that are shown as sheet metal members welded to the respective walls. The same minimize buckling of the fire box walls under expansion and contraction induced by heating and cooling.

The upper half 15 is preferably the larger half, because the same, on its top 17, is provided with an outer collar 34 which, ordinarily, would interfere with nesting within the other fire box half. As shown in Figs. 1 and 3, said collar orflange 34 is placed near the back of the fire box and serves to receive the flue or stack 11. The

latter, in this instance, is shown as two separably connected tubes 35 and 36, the former connecting to flange 34 and the latter to the upper end of the former. A damper control37 may be provided in one of the flue tubes, in this case the lower one 35.

From the above construction, it will be seen that adjustment of the draft and damper controls may be readi ly effected to produce a greater or lesser movement of air across or through a fire in the fire box. Such control may be effected with the fire box otherwise closed. Only when stoking is it necessary to open the front doors 20 and/ or 27.

The set of legs 12 is shown as comprising four legs 38 in corner arrangement and connected to the lower half 16 of the fire box as by sockets 39 afiixed to the inner faces of the side walls 25 of said lower half. Said sockets are placed inside the half 16 so as not to interfere with proper nesting of the halves. Each leg 38 is provided with a stop flange 40 near its upper end, the same limiting the extent of engagement of said end in its socket. The lower ends of the legs are formed so they spread to provide a stable base for the stove.

The pair of warming shelves 13 is shown as similar rectangular shelf members 41 that may be variously formed and which, as shown, comprise a frame 42 surrounding a perforated or comparable support top 43.

Said frame and top are generally flat and along one side thereof there is provided an angularly bent lug or the like 44 at each end, substantially as shown. The side walls 18 of the fire box half15 are each provided with a pair of sockets 45 that receive lugs 44 and,"therefore, are spaced according to the longitudinal spacing of said lugs. Said sockets are so located that the warming shelves are in desired flush or nearly'flu'sh' association with the stove top 17 when the lugs 44 are entered thereinto.

When the fire box halves 15 and 16 are nested, the flanges 23 and 30 (Fig. 8) engage to constitute a pair of relatively strong longitudinal flanges, and flange's'24 and 3 1 (Fig. 7) engage to constitute a relatively strong transverse flange. Since the sockets 39 are on the inner faces of the side of the inner half 16, 'said halves nest one within the other, as in Figs. 7 and 8.

The flue sections 35 and 36, the legs 38, and the warming shelves 41, are made of a length to fit within the inner half 16. The arrangement may vary, the drawings (Figs. 7 and 8) showing a suggested arrangement of said parts within the inner half 16. 1

When arranged as above described, the open top the nested halves may be closed by member 14 which is provided with opposite longitudinal flanges 46 which engage with the superposed flanges 23 and 30 on each side, with an end flange 47 that engages and is limited by the door 20 of the outer half 15, and a spring catch 48 on the end opposite to flange 47 and adapted to have spring retention with flange 31 of the inner half 16. Said closure 14 is slid into place and, when retained by the catch 48, renders the components unitary and compact. Since the flanges 46 are inwardly bent, the closure retains its position against outward displacement and, since the door 20 is hinged to swing outwardly, the flange 47 prevents such movement.

The compact unit above provided may be easily handled and facility of handling is improved by providing one side wall 18 with a folding handle 49.

While the foregoing has illustrated and described what is now contemplated to be the best mode of carrying out the invention, the construction is, of course, subject to modification without departing from the spirit and scope of the invention. It is, therefore, not desired to restrict the invention to the particular form of construction illustrated and described, but to cover all modifications that may fall within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A knock-down camp stove, comprising a fire box formed of upper and lower halves of rectilinear form, one being smaller than the other, whereby the two halves are adapted to nest with the smaller inside the larger half, each half being provided with longitudinal outturned flanges along the side edges thereof and with flanges along one end edge, said flanges being respec tively superposed and engaged with each other when the halves are nested and when the same are arranged with the halves in mutually inverted relation to form a fire box space, said nested 'halves" being open within the flange-provided edges thereof, and a closure plate across the opening in the inner half and extending over the superposed flanges when the halves are nested, a longitudinal intu rned flange along each side edge of the closure plate, said plate being adapted to he slid over said opening, from the ends of the nested halves that have the end flanges, with the inturned flanges engaged beneath the side flanges of said larger half.

2. A camp stove according to claim 1 in which the closure plate is provided with a spring catch at the end thereof that is disposed over the end flanges of the nested halves, said catch engaging said end flanges to limit the slid-on position of the closure plate.
