UNITED STATES PATENT OFFICE COLLAPSIBLE STOVE Everett L. Jones, Twila, Ky.

Application February 11, 1936, Serial No. 63,429

This invention relates to a collapsible stove, and it is primarily an object of the invention to provide a device of this kind which is of especial advantage in camping, and the invention further has for an object the provision of a stove which can be used with equal advantage for ordinary cooking'purposes, broiling or in preparing food of a barbecue style.

A still further object of the invention is to provide a stove constructed in a manner which,

when not in use, may be compacted to occupy a minimum of space to facilitate either storage or transportation and which can be readily extended into adjustment without requiring any particular skill.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved collapsible stove whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be herematter more fully set forth.

Thenovel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:-

Figure 1 is a transverse vertical sectional view taken through a stove constructed in accordance with an embodiment of my invention, certain of the parts having a second position indicated by broken lines;

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1 looking in the direction of the arrow, certain of the parts being in fragment;

Figure 3 is a horizontal sectional view taken 40 substantially on the line 3-3 of Figure 1 looking in the direction of the arrow;

Figure 4 is a view in perspective of the stove in its folded or compacted adjustment;

Figure 5 is a fragmentary view in perspective 45 of a portion of one of the grate sections as herein comprised.

As disclosed in the accompanying drawings, I denotes a front panel of the stove and 2 the rear panel, both being made of sheet metal and The end portions of these panels I and 2 are hingedly connected, as at 3, with the end panels 4 also of sheet metal and of preferredsize. The hinge. connections 3 between the panels l, 2, and 4' permit a collapsing 55 of the panels as indicated in Figure 4 with the bottom panel 5 and the front panel I in overlying relation. This adjustment of the bottom panel 5 is permitted asa marginal portion of the bottom panel 5 is hing'edly connected, as at 6, to the lowerma'rginal portion of the front panel i, said hinge'co'nnection permitting the bottom panel 5' to be readily swung into the compacted or folded position as indicatedin Figure 4, or to be adjusted "in the opposite direction to bridge the space or area defined by the panels I, 2 and 4 when the stove is'extended for use as illus trated in Figures 1 and 2. V I

The bottom panel 5 is also of sheet metal and is of such dimensions as to have the panels I, 2 and 4 resting thereon from above when the structure is extended for use. The cornerportions of the bottom panel5 are also provided with the openings 1 through which areinserted from below the reduced portions 8 provided at the upper ends of the stakes 9. These stakes 9 are of any length desired and are adapted to be driven into the ground to provide means for supporting the stove structure in working position. These stakes 9 are of particular advantage in placing the stove for use upon a hillside as, of course, the required level of the stove may be attained by selectively driving the stakes the required distances into the ground. These stakes 9 may be of any material which is believed to best meet the requirements of practice.

The panel I in its central part and closely adjacent to its "lower margin is provided with a draft opening ID of suitable size while the central part of the rear panel 2 in its top portion is provided with a flue opening H. The side marginal portions of the opening I] are defined by the outstanding flanges l2 substantially perpendicular to the panel 2 while the upper margin of the opening H is defined by an upwardly iinclin'ed flange I l. The panel 2 ate. point below the opening ll and substantially centralthereof carries an outstanding headed member l5.

' A collapsible chimney C is comprised in my improved stove structure and isadapted when position for communication with the interior of the extended stove structure through the flue opening ll. When applied the chimney G ex tends upwardly and laterally from the rear panel 2 on a predetermined angle of inclination. When thechimney C is applied the flanges l2 of the rear panel 2 are snugly received within the lower end of the chimney while the lower end portion of the top wall, N5 of thechimney engages over the upwardly and outwardly inclined flange I l. The lower end of the bottom wall ll of the 2; a chimney carries a slotted depending portion l8 which engages over the headedshank l and has close contact with the rear panel '2. By this means the chimney C is effectively maintained in applied or working position yet can be readily removed as desired.

The panels I and 2 substantially midway their ends have secured to their inner faces the upstanding lugs l9 and '20 inwardly offset with respect totheir associated panels I and 2. The

lug IQ of the panel is above'the draft opening 7 l0 and the lug 20 of the rear panel 2 is below the flue opening H but their upper endsare substantially coplanar.

The end panels 4 have ,hingedly connected thereto, as at 2|, the outer end portions of the grate sections 22 and 23, said sections substantially snugly fitting between the front and rear panels and 2 of the stove when the structure is extended for use and said sections also being a of a lengthj'slightl'y in excess of one-half the distance between the end panels 4 when in opera-V 'tive position so that the free endportions of one of the sections,as 23, will lap or overlie the free end portion of the second grate section 22. The

free end portion of the grate section22 is provided with short outstanding lateral extensions 24 terminating in the perpendicularly related lugs 25 whichengage between the lugs l9 and 23 and the associated panels I and 2 whereby the grate; section 2211s supported'iniproper position for use, and at the same time the central pore tions of the front andrear, panels I and. 2 are effectively held against outward separating movement while of'course said front and rear panels also havetheir central portions held against in mud flex g-a s f Thefree end portion of thegrate section 22 is also provided with the transversely spaced openings or slots 26 which receivethe lugs 21' struck from the outer end portion of the grate section 23. By this means the extended grate sections 22 and 23 are held in assembled position and at the same time means are provided for further effectively maintaining the panels I, 2, and 4 in proper extended or working adjustment.

The upper marginal portion of the front panel I has hingedly connected thereto, as at 28, a grill 7 plate 29 which is of a length slightly in excess of the space between the end panels 4 when the stove-is extended so that when said grill plate 29 panel 2 and in order to permit the passage of the to. its normal position. the head 32 willbe thrown is swung across the top of the open top of the stove -such plate will be effectively supported by the end panels 4. The marginal portion of this grill fplate 29 opposite its hinge connection 28 is provided in its central part'with a slot 30 through which is insertable an upstanding lug 3| andits head 32' carried by the adjacent portion of the rear panel 2. The head 32 ofthe lug 3| is disposed at the side of the lug 3| toward the rear lug 3| and' its head 32 through the opening or slot 30 it is necessary that the upper central portionof the rearpan'el, 2 be forced'or flexed inwardly, and as such portion of the panel 2 returns over the adjacent portion of the-grill plate 29 whereby said grill plate is-effectively held, in- Working'position. I H V 1 When the grill plate stove is extended, it may be readily swung ,en-

tirely free of the opentop of the stove and .to a position overlying the outer face of the front.

panel ,I as is indicated by broken lines in Figure 1. 7

29 is not in andthe- The upper marginal portion of' the rear panel 2 has hingedly connected therewith, as at 33, a.

marginal portion of a'solid stove top plate 34 of sheet metal and also of a lengthslightly greater] than the space between the end panels 4 of the extended stove. This plate 34 when disposed over the open top of the stove is usedfor ordinary cooking purposes and while it can be thrown across the top of the stove with thesgrill plate 29 in its exterior adjustment, said stove top plate 34 may be adjusted over the top of the grill plate 29 while said grill plate is-still in applied position over the top of the stove as indicated by broken lines in Figure 1.

When the top plate 34 is not in use it swings entirely to one side of the open top of the stove and, as illustratedinFigure 1, is supported in its non-workingposition by contact with the top wall I6 of the applied chimney C. V

Should it be desired to cook food in a barbecue style, the grill plate 28 isthrowninto its position as, indicated by'broken lines ,in Figure .1 while the top plate 34 is thrown into its position' as illustrated by full lines in thesamemfigure, This leaves the top of the stove entirely openand the food to be cooked may be placed-upon'a; spit and readily supported above the fire car ried by the grate sections 22 and 23. Furthermore, in camp shouldit bedesired to have the benefit of the stove purelyas a camp fire,*the.

plates 29 and 34 will be adjusted in; the same manner just mentioned whendesired to cook. in barbecue style. a

My improved stove can be nection with different kinds of fuel such as wood, coal, or charcoal, and in -view of, the fore going description itis believed to be apparent that when desired it can be readily compacted to facilitate transportation or storage.- It is also.

believed to be equally obvious that if desired it can be extended for use without requiring any particular skill.

From the foregoing description it is thoughttov be obvious that a collapsible stove constructed in accordance withmy invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modi-Z fication without departing from the principles and spirit thereof'and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying. ,outmy inj vention in practice except as hereinafter claimed.
