PORTABLE STOVE.

Application filed March 30, 1923. Serial'No. 628,764.

make and use the same, reference being had to the accompanying drawings, .and to the figures ofreference marked thereon, which form a part of this specification.

This invention relates to portable stoves and particularly to that class known as camp stoves generally used by campers or motorists. This application is one of a series of applications filed by me on portable stoves, co-pending applications Serial Nos. 627,329, 627,330, and 634,138, being directed to subject matter not claimed here- The primary object of this invention is to provide a portable stove which can be knocked-down or collapsed into a relatively small. case for transportation and it is desirable in such a device to provide means whereby the v.stove can be readily set up for use. L

In the present embodiment ofmy invention I have provided a'stove in whichan oven may be provided, adapted to be set upon the base or collapsed and contained within the base. The present embodiment of the invention comprehends a stove, the base of which is about the size of an ordi-z nary suit-case and it is so arranged that all of the operating parts can be contained within it in a compact manner. However, the parts may be set up to make a stove with an oven of an appreciable size adapted to etficiently utilize the heat of a plurality of burners.

There are other features of the invention which are important but these are incorporated in other applications for patents, the present application being limited to the general organization which permits the parts to be contained within the base or case in a convenient manner and which also permits them to be readily set up for use.

The preferred embodiment of my invention will be apparent by reference to the following description in connection with the accompanying drawings, in which Fig. 1 is a. perspective view of a complete stove in a -knocke'd-down" state with the parts enclosed in the case.

Fig. 2 is a perspective View showing the interior of the case. the burner or cover plate and two end wings of the oven.

Fig. 3 is a cross sectionalview through the case, showing the parts contained therein.

set up ready for use, and

Fig. 5 is a top plan view of the stove showing the burner plate in a vertical position. v

The case 1 constitutes the base of the stove and it ,is shown as a rectangular case with a cover 2 hinged along one longitudinal edge. The base may be supported upon legs or rests 3 and 4. Each rest is'shown as comprising a transverse bar 5 with right angularly extending end members 6 and 7 terminating in upstanding arms 8 and 9, the ends of which are trunnioned in the end portionsof the case 1; Therefore, the restcan be swung downwardly to assume the position shown in Fig. 1 when the stove is set up or they may be swung so that the portions 7, 8, 9 and 10 lie against the sides of the case with the bar 5 lying close to'the end of the case, as shown in F ig, 1 when the deviceis knocked down ready to be transported.

In order to assist in carrying the case I provide a handle 10 secured to one side wall of the case. The cover 2 carries a latch 11 which may fit over a bed 12 on the case 1 to thereby holdthe cover in closed position.

A burner plate or top 13 ishingedto one longitudinal edge of the case by hinges 14 and in the embodiment selected for illustrative purposes the top 13 carries spiders 15 and 16 which constitute restsfor the cooking utensils and also permit the heat fromthe burners to pass into the oven when the oven is set up.

The fuel is supplied from a liquid container or tank 17, which may be filled by re moving the plug 18 and the liquid inthe tank may be put under pressure by a pump Fig. t is a perspective view. of the stove 19 contained within the tank and operable from the outside.

The tank is swinging-1y supported on the case by means of two curved arms 20 and 21, which are mounted in brackets 22 and 23. The arm 21 is hollow and it communicates through. a bushing 24 with a supply pipe 25, which leads to a vaporizing tube 26, discharging into a mixing chamber 27, one of the burners being controlled by a valve on the end of the stem 28. The mixing chamber communicates with the manifold 29, on the ends of which are burners and 31.

' The mixing chamber, the manifold and the burners are all rigidly connected together'and by, mounting the burners 30 and 31 on the arms 32 and 33, pivoted at 34 and 35, to the bottom of the case 1, the burners can be moved out of line with the vaporizing chamber or toward the back of the case to permit .the tank to be swung over into the position shown in Figs. 2 and 3.

\Vhen it is desired. to collapse the stove, the shifting movement of the burners and manifold may be accomplished by a bar 36, extending through one end of the case 1 and connected to the manifold, as shown in Fig. 5.

The member 37 is a bracket to support one end of the vaporizer 26 and it straddles the manifold so that the manifold may freely lnove when it is operated from the bar 36.

The hinged cover 2 carries at one end an end wing 38, co-extensive with the width of the cover and at the other end an en wing 39, which'is approximately one-half the width of the cover, there being a separate wing or door 40 hinged adjacent to the member 39 which may swing independently thereof. The combined width of the memhers 39 and 40 is approximately'equal to the width of the cover 2. The door 40 has a latch 41 with a lug 42 thereon, which may engage the inner face of the member 39 to hold the door closed The cover 2 and the end members 38, 39 and 40 constitute three sides of the oven. The fourth side consists of a plate 43 which has slots 44 and 45 engaged by the notched lugs 46 and 47. Carried by the members 38 and 40 and at the top of the member 43 is an oven top 48,

hinged to 43 and which carries hooks 49 and 50 to engage the upper edge of the cover 2, the members 43 and 48 being -.held in place by the latch 11,.which engages over the tongue 51 carried by the top 48, as will be clearlyseen in Fig. 4.

The end member 39 carries a lug 52, which engages in a slot 53 in the member 43. The member 38 has a similar lug 54Which engages in the slot 55 in the member 43, as will be seen by reference to Fig. 4. The members 2 and 43 have slots 56 and 57 to to be operated by a key 60 which may be fastened to' the case by a chain 61. The mixture to-the burners may be controlled by a valve on the end of the stem 28, both stems being accessible from the outside of the stove.

' The burner 31 is shown as carrying a priming cup 62, which will receive the liquid fuel when the burners are shifted over to the rear side of the case. The priming cup will then be under the vaporizer 26 so that it will locally apply heat to the vaporizer to get it hot enough to etliciently vaporize the fuel into the mixing chamber 27, but the priming cup feature of this invention Is not claimed in this application because it forms the subject matter of another application. 1

The plate 15 is provided with depending flanges which may engagestruck-out stop - members 63 and 63 in the ends of the case.

Therefore, the plate will be supported at one edge by the hinges 14 and at the other by the stop members 63 and 63'.

\Vhen the parts are assembled in the case, the burners will be shifted over to the position shown in Fig. 2; the tank will be swung inside the case, the top 13 will lie upon the stop members 63 and 63, and the members 43 and 48 will be folded one upon the other and placed upon the top 13. The end members 38, 39 and 40 will be folded over on the inside face of the cover 2; the cover will then ,beclosed down on the case and the rest will be folded up over the case as shown in Fig. 1. The entire stove will then be encompassed in a relatively small space, easily transportable.

\Vhen it is desired to set up the stove, the movable parts will vbe taken out of the ease, the tank will be swung over to the positions shown in-Figs..4 and 5 and the oven will then be set up as heretofore explained. When the members 43 and 48 are fastened to the ends 38,39 and 40 and to the cover 2, the oven will be in effect a unitary structure with the door 40.adapted to be swung into closed or open position. Therefore, when the parts are set up as shown in Fig. 4 and it is desired to cook on the stove, for example-as in boiling, the entire oven can be swung back to a horizontal plane, inwhich position it will serve as a warming oven and if the wind is strong, the hinged members 43 and '48 can be removed, leaving the end walls 38, 39 and 40' in the cover 2 to constitute a wind break.

It will be seen from the foregoing that the stove-can be collapsed in a compact mancase provided with a hinged cover, a burner ring plate hinged within the case at' one edge of the plate, stops in the case to support the free end of the plate, a burner mechanism within'the case, a fuel supply tank for the burner mechanism swingingly secured to the case whereby it may be moved to one-position outside the case and moved to another position inside the case,-legs carried by the case having swingin movements whereby in one position the egs can lie closely against the case and when in another position they will lie away from the case to support the .case above the lower ends-0f the rests, and means "for holding the cover in a-closed position. b v
