To all whom it may concern:

. Be it known .thatI, MARK L. ,S YM UR, a citizen of the United States, resigilin at Potlatch, in {the county .of 'Latahand Silzate of Idaho, have invented certain new and useful Improvements in Portable Cooking- Stoves, ofiwhichthe-following is a specification.

The present invention relates to an improved portable cooking stove, designed especially for camping purposes to provide an outfit that may with facility be packed for storage or conveyance, and with equal facility assembled for cooking purposes. The stove is designed to use hydrocarbon as a fuel, and for this purpose is equipped with a tank to contain the liquid fuel under pressure so that the necessary feed may be obtained from the tank to the burners.

The primary object of the invention is the provision of a foldable and portable camping outfit that will be comparatively light of weight and compact in its arrangement rendering it easy to manipulate when transporting or carrying, and which also is com paratively perfect in performing the functions of a cooking stove.

The invention consists essentially in certain novel combinations and arrangements of parts as will be hereinafter set forth and claimed. In the accompanying drawings one complete example of the physical embodiment of the invention is illustrated,

constructed and arranged according to the best mode so far devised for the practical application of the principles of the invention. i

Figure 1 is a perspective view of the stove are the tank 1 and the tray. 2, hinged to the tank at 3, both being made preferably of sheet metal, and somewhat of the same design as suit-.case, there being a handle 5 on the tank by which th e i e m y e carried. The liquid fuel or hydrocarbon is carriedm the tank, and of course it is sealed at the joints, with a filling cap or inlet 1,

6 operable from outside the tankto compress air within the tank ,to,,place the'liquid fuel underpressure to be fed to the burners,

which, under normal. conditions are above the tank. I I

The grid 7 is of rectangular shape and preferably of cast iron, having at each of its four corners a socket head 8 each de signed to fit over the end of one of the legs 9. Theselegs are made up of two U-shaped members, pivoted or hinged at 10 at the inner side of the end. walls of the tray 2 so that the legs may be turned up to vertical position shown in Fig. 1, or they may may be used to regulate the supply of liquid from the tank to the burners.

When not in use for cooking purposes, these two burners may be turned back on their swivel joints to fit into one of the grooves 16 adapted to receive the pipe 12, and the circular recess 17 adapted to receive the burner itself. 1

To protect the burners from wind, it may be necessary at times to use the wind shields as 18 18, one at one side and one at an end ofthe tray, and these may be held in place by spring clips 19 attached to the inner side of the tray walls. When not in use .and the tank is provided withan air pump the shields, which are of flat sheet metal;

may be stored in the bottom of the tray, together with the grid 7, which, it will readily be seen is a skeleton frame work designed to support cooking utensils above the burners.

In setting up the outfit for cooking'the device, is opened on its hinges, with the tank and tray level on the ground, thetwo pairs of legs are then turned up to vertical position and the sockets of the grid are placed in position on the legs. However, before the grid is set in place, the burners are swung on their pivots, out from their grooves and recesses, to position Within the tray, and when all is ready, the valves are turned and the oil or gasolene lighted at the burners.

From the above description taken in con nection with the drawings it is evident that a comparatively perfect device of this character is provided for accomplishing its intended results.

Claims:

1. The combination in a portable stove, of a sealed tank formed with an open groove and having a recess as described, a hinged tray, and a grid, a burner having a supply pipe swiveled in the walls of the groove of thetank to occupy the groove and recess, and said burner and pipe adapted to be turned to operative position in the tray, for the purpose described.

2. In a portable cooking stove, the combination of a sealed tank having means therein for creating air pressure on contained liquid fuel, a groove and a recess in the tank, a burner having an elbow connection swiveled in the walls of the groove, a tray hinged to the tank, hinged legs in the tray, and a grid on said legs, said burner being adapted to be turned into the tray beneath the grid for use, as described.

In testimony whereof I afiix my signa- V ture.

MARK 'L. SEYMOUR.
