Claims.

This invention relates to outdoor stoves, the object being to provide a new and improved form and structural arrangement of sheet metal parts permitting the same to be readily assembled for use or disassembled and nested together permitting it to be readily carried in an automobile or other conveyance for use at distant points as by picnickers or by others who may desire to utilize an outdoor stove for the cooking of various foods.

These general objects and specific features of construction are hereinafter more specifically set forth and claimed and the preferred form of construction of an outdoor stove embodying my invention is shown in the accompanying drawings in which- Fig. 1 is a perspective view showing the parts assembled for use.

Fig. 2 is a perspective view showing several of the parts in. the artially disassembled relation. to illustratethe construction and manner of assembly thereof.

Fig. 3 is a longitudinal section of the assembled stove parts taken on line 3-3 of Fig. l.

Fig. 4 is a vertical cross section of the assembled stove parts taken on line 4--4 of Fig. 1.

The stove, according to my invention, comprises two end members of like form, indicated at and 2. Each end member consists of two. strap iron leg portions turned bottom ends 4 providing feet for engagement with the ground or other surface. legs extend upwardly by an inwardly inclined portion 3 and thence by a vertical portion 5 and an. outwardly inclined portion pieces 1 to each of which a plate 8 is secured having an inner edge 9 off-set as shown andprovidedwithsimilar slots It and H at the opposite ends.

The two end members are supported in opposed relation as shown in Fig. 2 by transverse angle bars l2, the vertical flange of each of which is of greater length than the horizontal 3, 3 each having out- 3 each having end flange and the ends of the vertical flange: are

notched to provide hook portions l3 which engage in slots l4 provided therefor in the plates i and 2 and in the legs 3 as will. be understood from Figs. 1, 2 and 3. The horizontal flangesof the angle bars 12 provide a support for a fire grate l5 which may be of any approved form and here shown as being of a corrugated sheet metal having apertures. The grate supports the fuel being burned and the apertures provide for discharge of ashes therebelow into an ash pan it which is formed of a sheet metal bottom plate transversely by Detroit, Mich., assignor to Mich., a, corhaving an upturned flange H at the rear edge and an upturned forward edge I] provided with apertures l8 aligning with apertures in a damper plate Ila positioned on the inside of the vertical flange ll of the ash pan as indicated by dotted linesin Fig. 2. The damper, plate may be moved means ofthe knob 19 which rides in the slot 20 providedin the plate, and the draft thus regulated by varying the effective area of the openings. Each of the vertical end members and 2 has an inturned flange Ia and 2a respectively, as will be seen clearly in, Fig. 3:, on which the ash pan |6is slidable.

I also provide a rear plate 2| having outwardly inclined side edges 22 and 23 corresponding to the inclination of the upper portions of the end members and 2 and on the inner face of the plate 2| are hook elements 24 and 25 having end portions insertable in the slots ll! of the flanges 9 of the top plates 8.

At its lower edge the side thereto a sheetmetal angle plate 26, the vertical flange of which is secured to the late 2| and the horizontal flange of which extends inwardly practically to abutment with the vertical flange of the crossbar l2 at the rear side of the stove. This plate 2| has two ears 2'! and 28 on the outer surface thereof to receive the ends of the hooks 29 and 30 secured to the underside of the horizontal flange of the angle plate 3| positioned at the rear of the stove as shown in Fig. 1 providing a shelf for articles and the vertical flange of the element 3| prevents utensils from being pushed off the rear side of the stove.

The space between the end members and 2 is closed by the plate 41 similar in form to the plate'2 above described, the lower edge of which. when in the position shown in Fig. 1. terminates just above the vertical flange ll of the ash pan. On: the outer face of the plate 4 is a'pair of strap iron arms 33 each rolled to form an eye 34 at its lower end and shaped at its upper end with a hook 35 which extends through the upper end of the plate 4 and. intothe slots ll of the plates 8 at the top of the side members I and 2. The upper end of the plate 4 has an outturned flange 36 forming a shelf at the table top.

The various parts of the stove in assembled relation are shown in Fig. l and it will be observed that, by grasping thering portions 34' of the elements 33 attached to the plate 4'. the plate 4 may be turned outwardly from the bottom and readily disassembled from the structure and,

plate 2| has secured for-ward side of when in use, naturally remains in a vertical plane.

When the parts are 1, there is an opening of rectangular form openings 4| and indicated by dotted lines at 43 in Fig. 3, to be utilized. This grating member includes a cross bar 44 and preferably I provide a U-shaped Wire element 45 pivoted at the ends on the rod which character providing a support for various types of cooking utensils.

the parts are self-sustainable. The front and back plates-4 and 2| are then se- 8 and similarly 25 of the plate 2! in the respective apertures [0.

The fire grate l5 may then be positioned on the horizontal flanges of the cross bars l2 and the ash pan l6 of the members I and 2.

In so positioning the parts, the horizontal flange of the angle iron 26 the rear cross bar l2 as will be understood from 4 while a similar angle iron 26a has its horizontal flange practically engaging the front cross bar l2. By this arrangement, practically all the air entering the stove from the bottom is caused to pass through the fire grate I 5.

of the straps 33, it may be readily turned outwardly permitting access to the fire and permitting replenishment thereof without disturbing the utensils on the top grid 40.

It is believed evident from the foregoing dehook members 35 and eyed of leg elements fixed to each of the side plates each having leg portions extending outwardly from the bottom of each plate, and an outwardly supported on the said last named means.

3. An outdoor stove of knock-down type coma pair of angle bars each having hooked ends extending through apereach of said front and back plates having an mturned flange at the bottom engaging the vertical member of the respective angle bar and closing the space between the said angle bars and the respective front and back plates thereby causing practically all air for combustion to flow through the fire-grate.

4. A sheet metal stove adapted to be readily assembled or disassembled, comprising a pair of sheet metal end members having leg portions, detachable means for supporting the end members in spaced relation, a horizontal plate supported at the top of each end member and extending inwardly thereof toward each other, a grating supported by the horizontal plates, the inner edges of said horizontal top plates having apertures adjacent each opposite side edge, a pair of sheet metal side plates each having elements to engage in the pair of apertures at the front and back of the stove, a back shelf for the rear side plate and a front shelf at the upper end of the front side plate, detachable means for supporting the end members in the desired spaced relation, a firegrate supported by the said means, an ash pan below the fire-grate in slidable relation with the end members, said ash pan comprising a sheet metal plate upturned at its opposite edges to provide a front and a rear flange, the front flange having apertures and an apertured damper plate slidably supported relative to the front flange to control air flow to the stove, the said front and rear flanges of the ash pan when closed aligning practically in contact with the lower edge of the front and rear side plates, and means associated with the bottom edges of the side plates preventing flow of air around the grating and practically causing all air entering the stove to pass through the fire-grate.

5. An outdoor stove of knock-down type comprising a pair of sheet metal end members each forming an end wall of the stove, cross bars providing a means intermediate the upper and lower ends of the end walls for detachably supporting the end members in spaced relation, a pair of leg elements secured to each sheet metal end member, plates supported on the upper ends of said leg members and spaced apart when the end members are secured in relative position, side members comprising sheet metal plates each detachably supported in normal engagement with the respective opposite side edges of the end plates and providing there 'th a comparatively rectangular space in cross section of greater length than width, a grid supported by the end members at the top, a grate-like means supported by the end plates therebelow and at a distance above the lower edge of the end plates for the support of a fuel, at least one of the side plates being supported in a manner permitting the same to be swung outwardly to provide access to the fire and permitting replenishment with fuel without disturbing utensils on the grid, an ash pan slidably supported between the end plates below the grate, and damper means at the forward end of the ash pan for controlling the draft.
