STOVE Filed April 29, 1936 JVM/fia Patented Apr. 5, 1938 UNITED STATES PATENT o1-FICE STOVE John H. Albrecht and Clarence G. Yarn, Des Moines, Iowa.

Application April 29, 1936, serial'l Natrium s claims. (o1. 126-29) The object of our invention is to provide for outdoor use a stove of very simple, durable and inexpensive construction.

Another object is to provide as a. part of such 5 stove a chimney or stack of novel construction and having novel features of cooperation 'with the stoveproper adapted when not in use to be placed inside the stove.

Another purpose is to provide a stove with such a stack, the parts having cooperating elements whereby the stack is soconnected with the stove body that it may be swung to its different positions without wholly disconnecting the stack from the stove body.

It is also our purpose to provide such a stack, relatively wide from side to side and narrow from front to rear when installed, so as to allow the draft from the stove to enter the stack across I substantially the entire width oi the stove.

o More particularly, it is our object to provide a stove of the kind under consideration, having side walls and provided with a grid at the top with a lid or lid members, which can be moved from position resting above the grid to position leaving the grid exposed when desired.

Another ,purposeis to provide such a stove with a lid member of the kind mentioned, which when swung forwardly will automatically assume a position where it Vmay be usedras a shelf.

Another object is to provide a stove with such lidlike members, which when covering the grid are supported by the stove side walls rather than by the grid, and which' form a cover for the stove when the latter is not in use, but which may be secured in cover forming position by `suitable means provided for the purpose.

Another object is to provide a stove of the kind under consideration having a grid, which can be readily disassembled for purposes of repair or replacement.

Still another purpose is to provide a stove with such a removable .grid having a handle hinged thereto.

Still a further object is to provide such a sto-ve with means for rotatably anchoring it in an outdoor location in such manner as `to permit its being swung about in accordance with changes in the wind. c u

With these and other objects `in view, our -.invention consists in the construction, larrangement and combination of the various parts'of our stove, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims, and illustrated in the accompanying drawing, in which:

' Our improved stove'hasthespaced side walls l0-and II. These may be provided vwith thereinforcing .ribs I2 and Ventilating holes I3a. The lower edges of the side walls I0 and vII, are strengthened and reinforced by being curled as at ,I3 around stiif rods I4. -At the upper edge of each side member I0 and I I, the material is bent inwardly to Eform a horizontal ilange 135, which terminates in a down-turned flange IB. l ,l Transverse rods .-I'I have `their ends extended through the flanges I6 and substantiallyabutting againstthewalls -I Il and II., as shown for instance in Figure 3 for forming a At the front and rear-of the stove, the material of the side walls, is vturned inwardly to form-inwardly extending verticall flanges I8, which terminate in rearwardly-extending,flanges I9 (see Figuresflgandfm. l c

At the bottom of the side Walls,V at each of the Yf ront and rear ends, a rodw'ZD is extended rthrough 4the walls and Ythe flanges vI9 and is provided with nuts 2I onits-ends.`` a u Between the anges I9 a tubular :sleeve `22 forms a spacer on eachrod 2D. We `preferably .provide `short sleevesf23vgon the rod 20 between each ange lzgand its adjacent side kII or yIl) as 4the case maybe.

Ihus the side walls are thoroughly A'bracedat the-bottom -and front and rear. y

At the front of the stove, the upper cornersof the side walls II and I,2--are.-connected, reinforced and braced by a transverse rod 2`4 onthe ends'of which are ordinary 'nuts 2 I', such asvthose on the rods F20. A similar Irod 25 is extended through theside walls-at their :upper rear parts, 4spaced forwardly a short ,distanceirom theirrear lends. On `the outer ends ofthe rod 25fare nuts 2 I.

At ythe front of the stove, a sheet 26 Aforms a 'Cil fuel and draft door. It has the rear-turned reinforcing flanges 21 at its side edges, and these flanges project upwardly above the sheet 26 and are pivotally mounted on the front upper rod 24.

Normally the door or the like 26 hangs in vertical position as shown in Figures 1 and 2, but may be swung upwardly and forwardly to admit fuel or air.

We provide our stove with what might be called lid members, which may be used for covering the grid when desired, or for forming part of an enclosure. Preferably there are two of these lid members. One is indicated generally at 28 and is provided at what is normally its front edge with a downeturned flange 29 (shown up-turned in the inverted position of the lid in F'igure 2), at what is normally its rear edge, with a downturned ange 30 and at its side edges with the down-turned flange 3|. f

At its front edge at its corners, the lid 28 is provided with slots 32 (see Figure 1). The flanges 3| are journaled on the rod 24 as shown for instance in Figures 1 and 2, and the slots 32 are of such size and shape in connection with the other parts that when the lid 28 is swung over from its position shown in Figure 1 to its position shown in Figure 2, the edges of the slots 32 will engage the flanges I8 at the forward edges of the side members for holding the lid 28 in forwardly projecting horizontal position totserve as a shelf.

The flanges 3l are arranged so as to fit down over the side Walls of the stove when the lid is in position for covering its share of the grid as shown in Figure 1. y

The flange 3D has notches 33 at its ends to permit the flange 3B to clear the flanges I5 at the upper edges of the side walls.

The flange 36 has at what is normally its lower edge a rearwardly extending flange 34 of such length as to readily pass between the flanges I6.

A somewhat similar lid member 35 has downturned flanges 36 at its side edges adapted to extend outside the side Walls of the stove when the lid member 35 is lowered. The rear ends of the flanges 36 are pivoted on the rod 25.

The lid 35 has at its rear edge adjacent its sides, the notches 31 to allow the lid member 35 to be swung from horizontal position shown in Figure l to upright'position shown in Figure 2, without'being interfered with by the upper edges of the side walls and their flanges I5.

The front edge of the lid 35 has the downturned flange 38 of such length as to readily pass between the flanges I 6 of the side members when the lid is down.

The parts are so arranged that when both lids are in grid covering position, the flange 38 rests substantially upon the flange 34 shown in dotted lines in Figure 2.

It is sometimes desirable to lock the lid 35 down so that it will hold the lid 28 down. This can be done in various ways. We have shown a U-shaped locking device 39, the arms of which may be slid through holes in the side wall of the stove and in theflange 36 and hold the lid in place.

The chimney, its shape and relation to the other parts, is of considerable importance and Will now be described. Considering the chimney in its upright position, it has the shape shown in Figures 1 and 2. Describing it as in its upright position and as made of sheet metal, it may be said that it hasthe rear wall 45 of considerably less width than the stove and adapted to extend from position flush with the bottom of the stove to position extending considerably above the stove.

At its side edges, the back member I5 has forwardly and laterally inclined flanges 46 terminating in rather narrow forwardly extending parallel, vertical flanges 41, so positioned as to fit snugly between the rear ends of the side walls of the stove. The lower ends of these flanges 41 arerpivoted on the lower rear rod 20 between the ends of the sleeve 22 thereon, and the side walls of the stove.

- T'Ihe flanges 41 of the chimney flt between the flanges I9 of the opposite sides of the stove, when the chimney is in upright position for use.

The chimney has a front wall 50, which is connected to the flanges 41 and is of such length that when the chimney is installed, the wall 50 projects slightly below the flanges I6 of the side walls and extends upwardly fiush with the upper edge of the wall flanges 45.

'I'here is thus left at the lower part of the chimney a smoke entrance opening indicated generally at A in Figure 2, which is substantially as wide and substantially as high as the stove.

Pivoted to the upper part of the wall 30 is a swinging hook 5I, which may be used to engage the lid 36 for holding it in raised position as shown in Figure 2.

The chimney may have a fore-and-aft cross plate 52 at the top, so that a coffee pot or the like may be set on one-half of the chimney if desired.

The side II is preferably provided with a suitable carrying handle 58.

A cross plate 53 may be detachably fastened in the bottom of the stove in any suitable Way or may be riveted in place if desired. This is preferably done at the time of installation, so

that up until that time the plate 53 will not inf terfere with the fol-ding of the stack or chimney into the body of the stove. 'Ihe plate 53 has a pivotal connection with a rod 54 set in a suitable base as of concrete, at 55. The purpose of this structure is to anchor the stove, so that it can not be readily removed or stolen, and yet to permit it to be turned to different positions in accordance with the direction of the wind, so as to thus make the most draft the most effective for the purpose for which the stove is used.

In Figures 5 and 6, We have Shown certain modification in the stove. In these igures, we have shown a removable one-piece grid, having a single lid member fastened thereto. The onepiece grid, indicated generally at B (Figure 5) comprises a sheet of metal forming a frame 60 with downturned flanges 8| at its side edges. These flanges terminate in in-turned flanges 62 adapted to rest on the flanges I5, such as has heretofore been referred to.

In this form of the invention, the flanges I6 may be omitted if desired.

TheV flanges 62 and I5 may be fastened together by short bolts 63.

Thesingle piece grid B has the grid members 64 formed in it by dies or the like.

A cover member 65 has the side flanges 66 journaled to the rear end o-f the grid B and adapted to be swung from horizontal position covering the grid to'upright position against the chimney as shown in Figure 5.

Some people may prefer one form of stove and some another. We rather lean toward the form shown in Figures 5 and 6, because we have found in our experience that the grid is the rst part of the stove to wear out, and the construction 75 aniram-r2 'shown in those figures makes it easy tov-quickly remove the old grid and replace itwith another. The grid may be thus sold and handled as a repair part, which makes: for the convenience of the user of the'stove.

Use'andadvantag'es K We shall now explain somewhat the use to which our improved stove may be put and endeavor to set forth some of its advantages.l It is intended to be used for burning wood by camping parties. v

It is obvious that it may be placed on the ground practically anywhere. The fire can be started in the stove, and the door 26 adjusted to control the draft. A'stew pan, pancakegriddle or the like can beset .on the lids 28 and 35.

Where the form of stove having the removable grid and lid is employed, it will be observed that upon any injury or undue wear to the grid, the grid and lid may be removed and new parts conveniently and easily installed.

It will be observed that while most camp stoves have cold spots at their rear ends near the sides, that the entire top of our stove will get hot and especially these cold spots will be eliminated, because of the fact that the draft in the chimney extends across the entire width of the stove.

The lid 28 may be tilted over from position shown in Figure 1 to position shown in Figure 2 to serve as a shelf and to expose the members I1 for use as a grid. The lid may be lifted to position shown in Figure 2, if it is desired to use the full size of the grid.

It will be seen that the grid may be used for broiling steaks or the like, and the stove may be readily adapted for almost any kind of outdoor cooking.

When it is desired, the lids can be swung to position shown in Figures 1 and 4 and locked by means of the member 39. The stove may be swung on its side and the chimney can be swung on the rear rod 2D from position shown in Figures 1 and 2 to position shown in Figure 4. Preferably the door 26 is first swung inwardly.

The stove may then be conveniently carried by means of the handle 58.
