COLLAPSIBLE STOVE.

Application filed December 19, 1914. Serial No. 878,034.

To all whom it may concern:

Be it known that I, Gnonen IEQIPICKUF,

a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Collapsible Stoves, of which the following is a specification.

This invention contemplatesan improved collapsible stove of simple construction which may be easily set up or collapsed by any inexperienced person.

One of the objects of the invention is to provide a collapsible stove of improved constr'uction in which the walls are permanently hinged together to be folded alongside each other into a compact bundle for transportation or storage. 7

Another object of the invention is to provide a collapsible stove having a collapsible oven constructed and mounted in a novel and improved way. 7

i The invention also relates to an improved .manner of connecting togetherv the parts of both the body of the' stove and the oven whereby the movements to be given the parts in folding or unfolding the stove will be ob-. vious from the relation of the parts, so that an inexperienced person can easily see how to set up or collapse the stove.

The invention further refers to the means for controlling the path of the products ofcombustion, so that the oven may be heated or not as desired.

The invention also refers to improved smoke-tight joints between the parts, and to other details of construction which will be fully pointed out in tion. 1 r

In the accompanying drawings, Figures 1 and 2 are respectively a topand bottom plan the following descripview with parts broken away illustrating a stove embodying thefeatures of my invention. Fig. 3 is an inside plan view of the stove spread out. Fig. 4 is a perspective view showing the stove in inverted position and partially folded. Figs. 5 and 6 are respectively a side and end elevation of the stove on a reduced scale. Fig. 7 is a vertical transverse section on line 7'( of Fig. 1.

Fig. 8 is a fragmental longitudinal vertical section on line 88 of Fig. 1.- Fig. 9 is an end view of the stove completely collapsed.

, Fig. 10 is a sectional detail illustrating the means for connecting the vertical walls of the stove to the top wall. Fig. 11 isa per-1f"- spective view of one of the stove legs. Fig.

12 is a fragmental elevation partially in section, illustratmg the collapsible stove-pipe.

I will, herein; describe the invention ac.

cording to the exemplary embodiment illustrated 1n the drawings without any intention, however, of limiting the invention to the arrangement of parts or the details of construction disclosed, except as defined in the language of the appended claims.

According to one feature of my invention, it is not necessary that the oven, nor indeed the bottom wall nor legs, be provided, inasmuch as a stove which would be very well suited for camping or similar purposes might comprise only the top wall and the.

vertical walls of the body, the lower edges of the vertical walls resting directly upon the ground. Such a stove would fall within the scope of my invention as regards the .manner of connecting the walls of the body portion together.

When the oven, bottom wall, legs, etc., are provided, the usefulness of the stove is not limited to camping and similar conditions, but is suitable for ordinary domestic use.

The feature of collapsibility f the oven,

aswell as of the-other parts, is'advantage'ous to the manufacturer in shipping as well as to the user in transportation and storage.

In the construction shown in the drawings, all of the parts, except the legs, are made of sheet metal which conduces to cheapness in manufacture and shipment, and

also to compactness of the collapsed structure and lightness of weight.

Proceeding now to the detailed descrip tion of the exemplary embodiment, the stove comprises a to plate or wall 15 having therein a suita le number of holes'16 arranged to be closed by the usual stovelids (not shown). When the top is made of sheet metal it may be reinforced by suitable bars 17 secured to the under side thereof. The top plate is provided at its rear end with a smoke opening 18 and a surrounding stove-pipe collar 19. (Fig. 12) is preferably made of telescopic The stove-pipe 20 sections arranged to collapse one within the other. If desired, means may be provided for locking the stove-pipe to the collar 19 of a bayonet slot 21 in the pipe adapted to receive a 'in 22 (Fig. 7 in the collar.

Vertica side walls 23 and 24, a front wall upon thetop plate.- This means may consist 25, and a rear wall :26 are provided, each of said Walls in the present instance being permanentlvhinged to the top wall 15 indetop wall ma or bead 27 vertical walls are bent to provide shoulders 30 arranged to abut against the under side of the top plate when the stove is set up,

as best seen in Figs. 7 and 8. These shoulders lend rigidity to the structure and provide smoke-tight joints between the vertical walls and the top plate. In the present instance, the hinge straps 29 are separately formed and are secured to the outer sides of the ofiset portions or shoulders 30.

The abutting vertical edges-of the walls at each corner ofthe stove are complementarily shaped to provide a smoke-tight joint.

The edge of one Wall is bent to form a groove 7 31 (Figs. 1, 2 and 3), while the edge of the other wall is formed into a bead 32 which constitutes a tongue or a wedge adapted to fit tightly in said groove to form an elfective joint. The walls are latched together at the cornersto prevent separation of'these joints by a suitable number of pairs of locking devices 33, each of which may consist of a notched plate fixed .to one wall and a plate pivoted to the other wall and adapted to enter the notch in the first plate.

The bottom wall 34 of the stove is secured in place by a slidable tongue-and-groove connection which, in the present instance,

comprises an angular flange or tongue 35 on' each of the two side walls 23, 24 and tine rear wall 26, said tongues running approximately coextensive with the walls and projecting outwardly therefrom. The lower edge ofthe front wall is bent to form a groove 36 opening inwardly. Thebottom wall 34 is also bent to provide inwardly opening grooves 37 running along its two sides and its rear end, and adapted to receive the tongues on the side and rear walls, while the forward edge of the bottom wall is arranged to enter the groove 36 at the-lower end of the front wall.

The legs 38 (Fig. 11) are provided at their upper ends with horizontal inwardly extending lugs 39 adapted to enter bowed straps or loops 40 fixed to the under side of the bottom wall 34.

In the front wall 25 is' provided a suitable draft-regulating means which, in the present instance, consist'sof a row of open-- ings 41 (Fig. 6) through the front wall proper and a slidable plate 42 having a row ranged to be moved into differentpositions relative to the first mentioned openings by' sliding the plate. The plate is guided by suitable strips 44 secured to the front wall and having their edges bent to overhang the edge of the slide plate. At opposite ends the plate 42 is provided with angular flanges 45 adapted to be engaged for moving the plate. I The side wall 24 is provided with a dooropening 46 (Fig. 7 for the oven, said opening. being closed by a door 47 hinged at one edge 48 and arranged to be held closedby suitable latch means 49 (Fig. 5). At the edge of the door-opening 46 the side wall is provided with inwardly. extending angular flanges 50 arranged to overlap the walls of the oven. The side wall 24 is also provided with a'door-opening 51 for the fire box arranged to be closed by a door 52 hinged at 53 and having suitable latch means 54 for holding it in closed position.

The oven comprises front and rear walls 55 and 56 and top and bottom walls 57 and 58. One of these walls, in this instance the frontwall 55, is hinged directly to the side wall .23 of the stove, whilethe other oven walls 56, 57 and 58 are not connected to the said stove wall 23, except through the front oven Wall 55. The said front wall .of the oven constitutes the rear wall of the fire box, said Wall at its lower edge contacting the bottom wall 34 of the stove-body and terminating at its upper edge short of the top wall of the stove to leave a space between the top wall of the oven and the top ofthe stove for the products of combustion to pass through.

At its hinged end the front oven-wall 55 has a shoulder or offset portion 59, the hinge 60 being formed at the edge of this shoulder and the latter being arranged to abut against the stove wall 23 when in normal position. The top oven-wall 57 is hinged to-the upper edge of the front wall 55 and the latter is provided with a shoulder 61 along its upper edge to limit the relative swinging movement of the two walls in one direction and to form a tight joint between the walls. The rear oven-wall 56 is pivoted to the rear edge of the top wall 57 and is provided with a shoulder 62 along its upper edge which forms a tight joint and limits swinging movement of the two walls away from each other in one direction. The bottom wall 58 is provided at its for ward. edge with an offset portion or shou1- der 63 which abuts against the front ovens .wall, and the edge of this shoulder is hinged to the lower edge of the said front wall. The shoulder 63 provides a space between the bottom wall of the oven and the bottom of the stove. The bottomoven-wall 58 has at its rear edge an angular flange 64 arthe latter.

ranged to overlap the lower edge of the rear oven-wall 56, the two walls being detachably secured together by suitable latches 65.

Theflange 64 is tightly clamped against the rear'wall 56 by the latch members thereon, as shown in Fig.8, so'that a tight joint is formed. Suitable stop flanges 66 fixed on'the side stove-wall 23 (best shown in Fig. 3) are adapted to determine the proper position of the oven walls in unfolding or setting up Said flanges also provide an overlap joint between the oven walls and the said side wall 23.

The rear oven wall 56 has rigidly fixed to its upper edge a plate 67 which extends upwardly into contact with the top wall 15 of the stove. 4

68 is an offset portion'in the upper edge of this plate to conform to the smoke-open- .ing 18 in the top wall. The plate 67 is only about half the horizontal length of the oven, or in other words is only about half as long as the stove is wide.'

To the bottom wall of the oven is rigidly fixed a plate 69 running from front to rear of the stove substantially along a longitudinal median line thereof and contacting the bottom stove-wall 34.

A damper 70 which is of a height substantially equal to the height of the interior of the stove, is hinged at its rear edge to the rear wall 26 of the stove and is provided with a handle 71 which projects through said rear wall to be manually operated for controlling the position of the damper. Preferably, the wall 67 is provided with a stop flange 72 at one end, and the wall 68 projects beyond the edge of the bottom wall 58 of the oven, so as to form upper and lower stops, against which the damper may abut when moved into operative position.

It will be noted that the stove-pipe collar 19 is locatedat one side of the longitudinal median line ofthe stove and directly behind theplate 67, so that said plate prevents the products of combustion from passing straight rearwardly to the smoke-opening 18.

When the damper 70 is in operative position, that is, perpendicularly to the rear wall of. the stove, the products of combustion .are compelled to pass downwardly behindthe oven at one side of the damper, thence in a curved path beneath the oven, as directed by the plate 68,. and then upwardly behind the oven at the opposite side of the damper and out through the stove-pipe.

Thus when it is desired to use the oven for baking, the oven is heated from all sides. Ordinarily products of combustion pass through the space above the oven and thence around the plate 67 to the stove-pipe.

When the stove is to be collapsed, the stove-pipe 20 is removed and the stove-body is preferably then turned up-side down to facilitate the removal of the legs and the bottom wall 34. After these partshave been removed the -catches 33 at the corners of the body are loosened and the walls are swung outwardly into the position shown in Fig. 3. The catches 65 for the oven walls 56 and 58 are then loosened andthe bottom' wall 58 1s swung around to the outer side' of the front wall of the oven, the rear oven-wall the side wall23 of the stove-body. The

plate 68 fixed to the bottom oven-wall is, of course, about the same height as the shoulder 63 of said wall so that the wall will be held in spaced relation to the front oven wall 55 when the oven is collapsed.

.The top wall 15 of the stoveis now raised -1nto position to permit ofswinging the end walls around to the normal upper face of said top wall,,whereupon the side wall 24 is swung over upon said end walls, aITd lastly the side wall 23 bearing the oven sections is swung alongside the other stove walls. The parts will then appear in rear end view as shown in Fig. 9, the oven walls being ontop. The bottom stove wall 34, legs 38 and the collapsed stove-pipe 20 may be packed with the collapsed body structure into a very compact bundle. Inasmuch as the parts are made of sheet metal they may be compressed into a smaller vertical dimension than illustrated in Fig. 9. I

The operation of setting up the stove is just the reverse of that just described and need be only briefly outlined. The parts are unfolded .into the position shown in Fig. 3, the oven walls are set up, the end stove-walls are raised, the side wall 23 bearlng the oven is raised and latched to the end walls, and the other. side wall. 24 is.

I attribute particular importance to the fact that all of the walls of the stove and oven (except-the bottom stove-wall) are per manently hinged together, because the inan ner of setting .up or collapsing the stove is thereby pointed out to an inexperienced person and it is practically impossible to associate the walls in improperxrelation.

The various shoulders and stop flanges also assist to this end'by preventing the walls fromvb'eing .swung in the wrong direction. Furthermore, when the walls are connected together the individual parts cannot be mis placed or lost.
