CAMP STOVE.

Specification of Letters Patent.

.Patented J une 20, 1922.

Application led February 5, 1921. Serial No. 442,867.

To all 'whom t may concern.'

Be it known that I, VINCENT LASBURY, a citizen of the United States, residin at Griggsvillc, in the county of Pike and tate of Illinois, have invented certain new and useful Improvements in Camp Stoves, of which the following is a specification, reference being had to the accompanying drawings, and to the reference characters marked thereon, which form a part of this speciiication.

This invention relates to portable, knockdown camp stoves.

One of the objects of my invention is to make a stove for campers use, which is not only easy to take apart and pack for shipment, but which is of such simple construction as to require'no expert experience in putting the parts together for use.

Another object of my invention is to abricate the several sections in such manner as to give the greatest amount of strength and greatest resistance to warping consistent with the use of thin gauge metal.

Another` object of the invention is to provide a simple and efficient construction as cheaply as possible and one which will not readily get out of order and require repairs.

The advantages oi' my invention will be more readily understood as I proceed with my specication; the invention consisting in the devices and combinations of devices described, illustrated and pointed out inthe appended claims.

In the drawings:

. Fig. 7 is a bottom plan view oi the top wall of the stove.

Fig.. 8 is a detail sectional view, enlarged, of a portion of the stove pipe opening, to

'more clearly show the connection between the stove pipe and the stove top.

In the drawing, A represents the stove as a whole, as shown in Fig. 1. This stove consists of a front end wall B, a rear end wall C, two side walls D, D, a telescopic pipe E, and a removable lid F for the cover or top of the stove G. The two side walls are of similar construction, but made right and left One only will be described.

A metal plate 1 of the desired dimensions, rectangular in shape, is provided at its lower -endv with a relatively stiif'rod 2, about which the lower edge of the metal 1 is wrapped, -so as to form the bead or support 3, which constitutes the bottom edge of the side wall D and rests upon the ground when the stove 'is in use. The top edge of the wall D is similarly provided with a rod 4L, enclosed within the bent over edge of the sheet metal 1 to ,form a bead 5. The two ends are rein- Jrorced by vertical plates placed on both sides of the sheet metal plate 1, so as to form a vertical longitudinal groove into which the flanges of the end wall C will fit. This construction is shown in Fig. 6, as follows: the edge of the sheet metal 1 is doubled upon itself as shown at 6. Vertical strengthening plates 7, 7 are placed one on each lide of the thickened edge 6 and secured thereto by rivets 8 or other suitable means,

thus forming between said strengthening `plates 7 the recess 9. At the lower end Voi'each plate D is an angle bar 10, riveted at the side of the outer plate 7 with its short member extending beyond and bent zover in front of the end edges of the strengthening plates 7, as shown at 11. This yangleibar 10, 11, thus forms a locking member at the lower corner of the wall D to secure and lock the end wall in position.

Th@J end wall C is strengthenedA at its upper and lower margins byy having the metal Abent upon itself, as shown at 13, 11i while at each margin of the end wall C, the metal is simply turned at right angles to form guide and locking flanges 15. These flanges 15 vare adapted to fit within the recess 9 and between the plates 7 7 of the side walls D, as indicated in the dotted line of Fig. li. d

The fronty wall B, so :tar as its top and bottom edges are concerned, and its side margins, is similarly constructed and will not therefore be further described in this particular.

It will be understood that when the two side walls D, D, are placed'in parallel relation, standing vertically upon their beaded edges 3, these may be united to form a rectangularly shaped box by first engaging the lower ends of the flanges 15 of the end wall C in the recess 9, and then pushing the entire plate C vertically downward until its lower endA is firmly locked by the projecting part 11 on each side wall D. The front wall B is similarly united to the forward margins of the side walls D, D. These four parts are then held firmly together by placing on the top the top wall G.

This top G is provided with a downwardly projecting .flange 16, formed by bending the end margins and the two side margins, and interlocking them at their overlapping, meeting edges, by rivets 17. This fiange 16, as clearly shown in Figs. 1, 4 and 5 will surround the upper margins of the end walls B, C, and the two side walls D, and completely hold the stove structure in rm relationship.

Near the front end of the top G, that is near the wall B, I make a lid opening which is covered by the lid F, and near the rear end, I make a smoke opening leading to the stove pipe E. This smoke opening is preferably rectangular in shape, as shown. The edge of this opening is protected by a binding which constitutes a flanged border for the pipe E. This binding is made by bending a piece of metal 18 upon itself as shown at- 19, to constitute the 4flange proper. The other edge of the metal 18 is bent outwardly at 20, on each of the four sides of the opening. The several parts 20, 20, thus press against the under side of the top G and are riveted thereto by rivets 21. The opening for the stove lid on the top G is made by cutting an aperture in the top G of a diameter somewhat less than the intended diameter of the finished opening, margin somewhat to form between the slits a series of circumferentially arranged lips 22. These lips 22 are bent inwardly so as to rest against lthe under surface of the top G, as clearly shown in Fig. '7. Thus the opening for the lid is substantially circumferential in shape., and is strengthened and defined by this double thickness of metal.

v The lid F is of a diameter slightly in eX- c'ess of the lid opening. It also is made of thin sheet metal, but is strengthened by a plate 23 secured thereto by rivets 24. The diameter of this strengthening plate is substantially that of the interior diameter of the lid opening in the top G. The strengthening plate 23 is provided with transverse ribs 25, 25, formed by fluting or bending the metal of the plate 23. Thus it will be clearly understood that the metal plate 23 resting from warping,

then slitting the within the opening in the top G, prevents improper shifting of the lid F with respect to the top G.

As a matter of convenience and economy of space it will be noted that the lid F and the opening that it covers are located in the front end of the stove, that the smoke opening and pipe are not only located at the back of the stove, but near one side of the top G, thereby affording the maximum space on the top G for cooking utensils.

YIn order to strengthen the top G to Asus'- tain the necessary weight that may be placed upon it in the cooking operation, and also to prevent the met-al ofv which it is composed I use two strengthening ribs 26, 27. The rib 26 is secured by rivets 2S transverselyof the under side of the top G and substantially across its central portion. It is fiuted as clearly shown at 29. The strengthening rib 27 is similarly secured by rivets 30 in such position as to run diagonally from one corner of the under side of the top G toward the front and near the strengthening rib 26. This rib 27 is likewise fiuted, as shown at 31. The rivets used are fiat top rivets as shown, sol that the sur face of the top vG is substantially flat.

While the two side walls D, D, are strengthened by the rods 2 and 4, yet the intermediate sheet metal is liable to warp to some extent and therefore I have found it desirable to place on the inside of each 0f the walls D slightly above the center thereof, a strengthening rib 32, secured to the wall D by rivets 33. Each of the ribs 32 is centrally bent or uted as indicated at 34. This makes a very strong construction.

The front wall B of the stove is provided with a sliding fuel door H which moves from side to side in top and bottom guide-V .ways. the lower guideway being indicated at 35 and the upper one at 36. These guideways are parallel to each other and extend from side to side of the wall. A suitable handle 37 is riveted to the door H.

y The door opening is strengthened and protected by having the sheet metal slit to form lugs or lips 38 bent outwardly from the door opening so asto lie fiat against the inside of the end wall B, to which said flaps 8S are riveted at 39. Thelower flap which I have designatedv at 40 however, is not riveted, but is merely bent over the double edge 41 of the lower margin of the end wall B. This makes a very strong construction.

A lug 42 is provided for the door H to afford a stop to limit the movement of the door. A suitable handle opening 43 for the lid F is provided to afford convenient access for a lid lifter. i

It will be noted that the stove pipe E is made in telescopic sections, the lower section 44 being provided with a strengthening flange 45 bent to form a shoulder 46. This shoulder 46 rests upon the top margin of the strengthening rib 18, clearly shown in Figs. 4 and 8. The other sections, one of which is indicated in Fig. 1 at 47 are merely rectangular devices that fit within each other in a familiar manner. Thus I may have a pipe as long as is necessary to maintain the proper draft in the stove, while at the same time, a pipe which is collapsible and may be conveniently packed.

49 is a wire or metal rod which is inclosed preferably within the lips 22 to form additional strength to the opening in the stove top, which is usually a weak point in a sheet metal stove. The wire adds stiffness to the metal at this point.

In shipping the stove, I remove the stove pipe E and lid F, turn the stove upside down so as to rest upon the top G, pack the lid and stove pipe therein, together with cooking utensils, etc., and tie the whole together for shipment in that form. More often, however, the entire stove will be taken apart and packed and shipped flat. When thus taken apart, the stove will consist of six flat pieces and the telescopic stove pipe E, thus occupying a minimum of space for shipping and handling purposes.
