United States Patent O PORTABLE STOVE Stephen C. Pepln, Lakewood, Ohio, assigner to Lakewood Manufacturing Company, Westlake, Ohio, a corporation of Ohio Application August 15, 1955, Serial No. 528,224

4 Claims. (Cl. 126-25) This invention relates in general to portable stoves of the general class disclosed in the United States patent to Anderson, No. 2,048,769, for Cooking Apparatus, July 28, 1936. The Anderson device includes a tire basket in the form of a base and end walls and a pair of wire mesh side walls. A bracket is connected to the top rim of the lire basket for supporting a broiler frame. Lugs are formed on the end walls for receiving supporting legs in two dilerent adjusted positions for supporting the fire basket vertically or horizontally.

Having thus generally dened the environment of my invention, among the objects of my invention are improved method and means of constructions, assembly and disassembly and adjustability of the portable stove, as a whole, into vertical and horizontal positions without the necessity of adjusting any of the component parts of the stove, such as the lire basket, legs or brackets.

The fabrication and assembly of my portable stove constitutes a great advance in the art in reduction of cost of material and labor. Moreover, it avoids the necessity of hinged joints, welding or soldering and the like. I merely take a length of iiat material, such as high heat resistant sheet metal. The middle portion of the sheet eventuates into the base and the other portions the end walls of the tire basket. At spaced points near the side edges of the sheet I punch the metal inwardly to form ears. Also, in the end walls I punch the metal outwa'rdly toV form clips to engage the supporting legs. I then form side anges on the strip of metal and bend it to form the base and end walls. With the ears in the base and side walls being adjacent the side anges, I may slide the two open mesh side walls between the two and crimp a top channel rim to complete the fabrication and assembly of the re basket.

The two main supporting legs are preferably spring wire loops, to the open upper ends of which are rigidly secured transverse brackets. The legs and the center portions of the brackets easily snap into engagement with the clips punched out of the end walls. When the main Y legs are supporting the re basket in vertical position, the two brackets are available for slidably supporting a pair of broiler frames and the top rim of the tire basket is available for supporting cooking utensils. is desired to utilize the stove as a horizontal stove, no adjustment is necessary. It is merely laid out horizontally and the brackets, in conjunction with the main legs, sup port the ire basket horizontally. This may even be done while the re basket is hot and loaded with burning fuel.

With the foregoing and other objects in View, the invention resides in the method and means of construction, the combination of parts and in the details of construction hereinafter set forth in the following specification and appended claims, certain embodiments of which are illustrated in the accompanying drawings, in which:

Figure 5 is a view in section taken along line 5-5'of Figure 2.

The main essential component of my` portable stove is the lire basket itself, which I generally indicate at A. In the interest of economy in material and labor in fabri` cation and assembly, I take a continuous strip of light weight heat resistant sheet metal and bend up side anges 1, 2 and 3 on each side of the strip. Having done this I slit the side flanges at points 4 and 5. Then I bend the strip at two points adjacent the slits 4 and 5 at right angles so as to form a channel base 6 and two channel end walls 7 and 8.

Prior to this bending operation I also punch out a pair of louvres 9 and 10 in the bottom wall 6 and two pairs of louvres in each of the end walls 7 and 8, these louvres being shown at 11 in end wall 7 in Fig. 1, the louvres in end wall 8 being in identical form as those shown at 11.

In addition, in each end wall I punch out of the metal of the end wall a pair of louvres 12 so as to form an open retaining clip that extends transversely of each end wall. Near the top of each end wall I punch out of the metal of the end wall a pair of horizontally spaced louvres 13, which provide for vertically downwardly extending open clips. With the Vtwo end walls and the bottom wall of the tire basket thus formed in the manner described I insert through the open top of the tire basket a pair of horizontally spaced screen members 14 and 141, which form the open mesh side walls of the fire basket. When each screen member is inserted it is forced vertically downwardly in such a manner as to be positioned between each side flange of the base 6 and the two end walls 7 and 8 and the clips formed by the punched out louvre of the base and the two end walls just described. In this manner the base and the two end walls are of one integral piece of sheet metal and the fabrication and as'- sembly involves no hinge members nor necessity of any soldering or welding operation. The same thing is true in the fabrication and assembly of the wire mesh side walls. With the assembly thus far progressed I take two channel strips 15 and 151, invert them and slip them over the top edges of the two wire mesh side walls and over the side anges of the two end walls and crimp the two inverted channel strips onto the anges of the end Walls to completed the assembly of the re basket itself.

In order to properly support the re basket into either vertical position, as shown in Fig. l, or a horizontal position, as shown in Fig. 2, I form a pair of legs, one of which is shown generally at 16 and the other at 17. Each leg is formed of a loop that affords two round engaging portions 18 and 19 and two vertically extending portions 20 and 21, which are of the same piece and integral with the remainder of the loop. Rigid with, or integral with, the leg standards 2l? and 21 is a crossbar generally indicated at 22 which is bent at 23 to engage the corresponding end wall and which extends at right angles to the plane of the surface of the wire mesh side walls as legs 24 and 2S. These legs 24 and 25 form brackets for slidably receiving broiler frames 26 of the conventional type in such a manner that they may be slidably moved toward and away from the external surfaces of the two wire mesh side walls for the purpose of moving the food contained in the broiler frames toward or away from the heat of the fire in the lire basket itself.

In order to assemble the supporting legs itis only Vheat resistant sheet metal.

Y clips oflouvres 12,'as shown inFig. `l. Thisprocedure having'been followed in connection with both supporting legs 16 and 17 the portable stove is in readiness for operation, including the deposit and igniting of the fuel inthe tireY basket and the positioning of the food-containing broiler frames while the assembly is in the position indicated in Fig. l for Vertical broiling. It is to be understood that in addition .to the suspension of one or both of the broiler frames onthe brackets 22 on both sides of the're basket there is ample space on the top of the two top channel frames 15 and 16 for food or beverage-containing pots and pans. Y

Itis to be borne in mind that both of the ire basket supporting legs and the Vbroiler frame supporting brackets comprise an integral construction in that the brackets are rigid with the supporting legs. Thus when the legs are installed in supporting position for the re basket the -broiler frame supporting brackets Vare also installed and the same thing is true with respect to removal of the supporting legs and the brackets as single units. Another new and novel feature of this construction and mode of assembly is that in the event it is desired to use the broiler not as a vertical broiler but as a horizontally disposed stove, Ythere is no necessity of any adjustment of any of the component parts of the assembly shown in Fig. l in order to position the portable stove as shown Vin Fig. 2. In'this position, only one of the round engaging loops 19 of the two legs 16 and 17 engage the ground while the legs 25' of the brackets 22 constitute the other groundY vided a portable stove, the fabrication and assembly of Vwhich constitutes a-great advance in the art inV reduction 'ofV cost of material and labor. Moreover, it avoids the necessity of hinged joints, welding or soldering and the like.r I merely take a length of flat material, such as high The middle portion Voi the sheet'eventuatesrinto the base and the otherV portions the end lwalls of the tire basket. At spaced points near the side edges of the sheet I punch the metal inwardly to form ears. VAlso, in the end walls I punch the metal outwardly to form clips to engage the supporting legs, VI then form side anges on the strip of metal and bend it to form the base and Vend walls. With the ears in the base and side walls being adjacent the side flanges, I may slide the twol open mesh side walls between the two and crimp a top channel rim to complete the fabricationv and assembly of the lire basket.

The two Vmain supporting legs are preferably spring Ywire loops, to the open upper ends of which are rigidly secured transverse brackets. Whether the brackets are integral with the legs or rigidly secured to the'legs, the 4brackets are supported by the legs and not by the brackets. The legs and the lcenter portions of the brackets easily snap into engagementwith the clips punched out of the 'end walls. When the main legs are supporting the tire :basket in vertical position, the two brackets are available `for slidably supporting a pair of broilerrframes and the top rim of the tire basket is available for supporting cooking utensils. When it is desired to utilize the stove as a horizontal stove, no adjustment is necessary.Y It is merely laid out horizontally, whether hotV or cold or full of -burning fuel, and the brackets, in conjunction with the Vmain legs, support therebasket horizontally.
