Toflztll whom it may concern:

Be it known that I, SAMUEL'S. CORNELIUS, a citizen ofthe United States, residing at Monett,'in the county of Barry and State of issouri, have invented a new and useful Outdoor Furnacepof which the following is a' specification. The device forming the subject matterof thisapplication is an outdoor furnace, and the "invention aims to provide, in combination with a furnace, a kettle having a novel means for bulging out a portion of the wall of the furnace, to provide a space'between the furnace and the kettle, so that the products of combustion may escape. J

It is Within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains- With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:-

Figure 1 shows in top plan, a device constructed in accordance with the present invention, the lid and the stack having been removed;

Fig. 2 is a vertical longitudinal section wherein the lid and the stack appear as added elements; and

Fig. 3 is a fragmental section taken approximately on the line 33 of Fig. 2.

Fig. 4 is a fragmental elevation of the kettle.

In the accompanying drawings, the numeral 1 indicates a tubular furnace, which may be made out of sheet iron or any other yieldable and somewhat resilient material, the furnace 1 being provided adjacent its lower end with a stoke opening 2 and having handles 25. A kettle 3 is seated in the upper end of the furnace, and is provided with an inclined supplemental wall 4, the lower end of which is joined as shown at 5 to the main wall of the kettle 3. \Vhen the kettle 3 is thrust downwardly into the furnace 1, the inclined wall 4 bulges out the Specification of Letters Patent.

furnace 1 at the back, so that, as shown at 17, a space exists between the main wall of the kettle 3 and the furnace 1. The upper end of the supplemental'wall 4 is connected with a flange 7 flange 7 overhanging and closing the upper end of the space 17 bulged out parts 6 of wall of the kettle. The flange 7 is extended, at a decreased width, around the periphery of the kettle 3 and, end of the furnace serves to uphold the kettle in the furnace. Thefiange 7 is suppliedwith a pipe collar 9 forming an outlet communicating with the space existing between the wall 4 and the main wall of the kettle. On the collar 9 may be mounted a stack 10. Plates 11 extend between the supplemental wall 4 and the main wall of the kettle and serve to reinforce and strengthen the wall 4. As shown at 12, the plates 11 terminate at some distance above the point where the lower end of the wall 4 joins the wall of the kettle as indicated at 5.

.The kettle 3 may be supplied withhandles 14, and upon the kettle may be placed a lid 15 having a handle 16.

In practical operation, the products of combustion generated in the furnace 1 below the kettle 3 pass upwardly through the space 17. Thence, the products of combustion pass laterally into the space between the supplemental wall 4 and the main wall of the kettle, below the plates 11, and as end, between the plates. through the collar 9 and out of the stack 10.

The structure hereinbefore described is of utility in that a kettle 3 of the kind herein alluded to, may simply be thrust down- ,wardly into an ordinary tubular furnace 1, the furnace being bulged as shown at 6, so as to permit the products of combustion to pass upwardly between the wall of the furnace and the main wall of the kettle, the products of combustion entering the spa e between the supplemental wall 4 and the main wall of the kettle. and ultimately lea ving by way of the collar 9 and stack 10.

person equipped with a kettle 3 of the kind mentioned, need not provide himself with any specific and specially constructed furnace since, when the kettle is thrust downwardly into the furnace, the furna e, although of the ordinary tubular construcon the kettle 3, the

formed between the the furnace and the coacting with the upper tion, will be so bulged that the products of combustion can escape.

Having thus described the invention, what is claimed is y 1. In a device of the class described, a tubular furnace; and a kettle seated in the furnace, the kettle having an offset supplemental wall which bulges the furnace 0utwardly to permit the products of combustion to pass upwardly between the kettle and the furnace, the kettle having an outwardly extended flange whereunto the upper end of the supplemental Wallis connected, the flange covering the upper end of the space existing between the kettle and the bulged part of the furnace, the flange having an outlet communicating with the space between the supplemental wall and the main wall of the kettle.

1 21A device ofthe class described, con structed as set forth in claim 1, and further characterizeclby the fact that upright plates main. wall extend between the supplemental wall and the} main wall ofthe kettle, the lower end of the supplemental wallbeing joined tothe f the kettle, and the plates ter- Gopies of this patent may be obtained for minating in spaced relationto the point of juncturebetween the supplemental wall and the main wall. 1'

3. In a device of the class described, a tubular furnace; and a kettle seated in the furnace, the kettle having an outwardly extended supplemental wall which bulges the furnace outwardly to permit the products of combustion to pass upwardly between the side of the kettle and the bulged part of the furnace, the kettle having an outwardlyfive cents each, byaddressinglthe Commissioner of Patents, Washington, D.
