CAMP STOVE OUTFIT.

Application filed October 27, 1924. Serial No; 746,061.

My invention provides an extremely simple and highly eiiicientstove of the type generally -designated as a camp stove, and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined' in the claims.

The so-called camp stoves are usually collapsible, so that they may be packed into relatively small space and carried in an automobile or other vehicle. The feature of compactness has been hitherto obtainedv with a sacrifice of efliciency. It has been the object of my invention to'provide a collapsible r stove adapted to burn gasoline or similar fluid fuel, which maybe folded up or col lapsed and readily carried in an automobile or other vehicle, and which, when set up for use, will compare favorably in efficiency with or will be equally efficient to the best grade of gasoline stove, and these objects, as I have thoroughly demonstrated in practice, have been substantially accomplished. Various other features and advantages, resulting from or incident to this improved form of stove, will appear in the following description of a commercial form of the irnproved stove, which is illustrated in the ac companying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective showing the improved stove completely set up and ready for use;

Fig. 2 is a perspective showing the stove with the grid and shield or housing removed; and

Fig. 3 is a perspective showing the collapsed or folded stove partly inserted into a carrying case.

In its preferred arrangement illustrated, the stove is provided with three burners indicated as entireties by the numeral 1i. These burners may be of any suitable vapor-gein erating type. Two thereof are spaced transversely and are connected to the Vouter ends of horizontally disposed pipes 5, the inner ends of which pipes are connected to a fourprongcd pipe coupling 6. The third and forwardly projecting burner 4L is connected by a very short pipe 7 to the front nipple of said coupling 6, and the rearv nipple of said coupling is connected to the upper end of an oblique pipe 8, the lowerend of which is connected to the upper intermediate portion of along (preferably cylindrical) gasoline or fuel tank 9. The tank 9 is preferably provided at its ends with dependingfoot brackets 10 that serve to hold the same slightly from the ground or floor. top, the tank 9 is provided with a valveequipped air-charging tube, to the outer end of which the discharge tube of an air pump is adapted to be attached. This valveequipped discharging tube is or may be of standard or well known construction, the details of whichl need not be here considered and, hence, the said valve-equipped tube is indicated as an entirety by the numeral 10.

To hold the burners elevated and in a horizontal plane when in use, I provide a collapsible supporting device, preferably constructed of wire and, as shown, comprising a bifurcated supporting leg 11 made out of a single piece of wire provided with coils 12 at its upper ends, pivotally embracing the respective pipes 5 adjacent to the coupling 6. The lower end of the leg 11 is spread so as to aord laterally spaced ground-engaging foot portions 18. At its intermediate portion, the wires of the leg 11 are brought close together and rigidly connected by a short transverse wire or small rod 14 sol-V dered, brazed or otherwise rigidly connected thereto.v The numeral 15 indicates a spacing rod provided at one end with a coil 16 pivoted on the intermediate portion of the short rod 14 and provided at its other end with an eye or loop 17 that will slide freely upon the lower portion of the oblique pipe 8. I-Iere it should be noted that the pipe 8 is providedk at its intermediate portion with a collar or pipe coupling 18 that limits the upward sliding movement` of the eye 17 on the pipe 8, to the position shown in Fig. 2, in which position the supporting leg will be properly positioned -to support the burners. The numeral 19 indicates a latch rod or hook, the upper end of which is bent to form a loop or eye 20 that pivotally surrounds the rear nip-ple of the coupling 6. At its lower end, the latch rod 19 is formed with a hook-like end 21 that is adapted to be sprung under andinto close engagement with the spacing rod 15 when the parts are adjusted as shown in Fig. 2.

In its TWhen the latch rod 19 is engaged with the spacing rod l5, as shown in Fig. 2, it will positively hold said rod l5 against sliding movements on the pipe 8 and, hence, will properly hold the supporting leg 1l so that the supporting structure Will be quite rigid and there will be no danger or' the saine collapsing, even it the entire device is shirted or slid around upon the ground or quite roughly handled.

l/Vlien the device is to be collapsed, it is only necessary to release the lovver end oi' the latch rod i9 from the spacing rod l5, and then to slide said rod l5 on the pipe 8 and turn the leg 'll up against said pipe 8.

To i'orn'i a complete stove in connectie with the generator and burn-r described, provide utensil-supporting grid .and housing in the `form of combined Wind shield plates and grid support. The grid is preferably made from a sheet or expanded steel and at its lour edges it is loosely set into the channels of lour channel bars 253, which vbars are rigidly connected at their ends and forni a marginal rectangular iframe. The iront and rear edge portions the traine 28 are loosely connected to the upper edges oi liront and rear Wind shield plates 25, by bale-like links Q6 that ici-init the plates and grid to be freely folded together, and when the plates are set .ferticaliy, shown in Fig. i, drop the Vtraine and grid slightly belou7 the upper edges of said plates 2l and 25. To the intermediate portions oi the end bars of the traine 23 are loosely pivoted oblique brace rods 27 provided at their free loiver ends with oil'set trunnions or projections 2S adapted to be slid endivise into anchoring brackets 29 riveted or otherivise rigidly secured to the respective plates 2l and 25.

The rear plate 25 is formed with a centrally located vertically deep notch 30 adapting the same to be dropped straddle ont the oblique pipe 8 so that the tank 9 Will be outside of the housing when the burners are preferably positioned under the grid.

rlhe stove, when set up for use as shown in Fig. l, Will have a large cooking capacity. The grid 22 will support a large ninnber oli utensils or a smaller number or utensils oit larger dimensions, and furthermore, the grid ivill be supported high above the ground, so that person manipulating the cooking does not need to kneel down nor to stoop to any considerable extent. The stove with three burners has very high cooking capacity and Where less cooking capacity is required, tie front burner may be omitted and the stove then provided will still have enough cooking capacity for ordinary tourists or campers purposes.

In Fig. 3, the numeral 3l indicates a casing adapted to receive the entire lolded stove structure and provided vvitli a hinged cover 32. Both the body and cover of this casing are preferably made et vulcanized vfood libre sheets.
