UNITED STATES PATENT OFFICE.

irA s c. rrANsoN, or ALBERT LEA, MINNESo'rA, AssIeNoR T AMERICAN GAS MACHINE COMPANY, or ALBERT LEA, MINNESOTA, A CORPORATION or To all whom it may concern:

Be it known that I,"HANS C. HANSON, a

'- citiien of the United States, residing at Albert Lea, in the county of Freeborn'and State of Minnesota, have invented a new and useful Improvement in Folding Camp- Stoves, of which the following is a specification. p This'invention relates to improvements in folding camp stoves, and more particularly to that type employing a hydrocarbon burner. More particularly this invention relates to a stove which can bepacked in compact form and easily and quickly unfolded and adjusted for use, and which when unfolded and adjusted produces a simple and effective stove for cooking and heating purposes. I

. In the accompanying drawing forming part of this specification, Figure 1 is a plan of my invention when packed fortransportation and the cover is removed; Fig. 2'is a section of a detail of the burners taken on the line X--X of Fig. 1; Fig. 3 is a section of a detail of the receptacle. looking at the side through which the handle 39 is adapted to move Fig. 4 is a section of a-detail of the receptacle when its body is erected on the cover; Fig. 5 is a section of a detail the casing, which is of rectangular .form and resembles a receptacle of medium depth, the

vbottomf2 of which isprovided with a plurality of draft openings 3 through which air is free to pass upwardlyinto the receptacle .to supply oxygen to the flames of the burners. .Each corner of the receptacle is provided with a movably disposed leg 4 in the form ofa vertical rod having afioli'set or shoulder 5 at its'upper end, said rod being slidably engaged in a tube -6 in the corner of thereceptacle, said tube being secured by rivets? or other suitable means to the casing and being provided with a longitudinal opening 8 or passage in its side through which the shoulder end of the rod may slide Application filed July 21, 1917.

.slot or lateral passage 10 in the tubular member where the leg is locked in extended position and. prevented from receding upwardly. In Fig. 3 the le is illustrated in folded condition while in Fig. 4 it is locked in extended position as described. The legs and their holding means are all similar inconstruction, there being one provided in each corner of the receptacle. The upper portions of'th'e sides 11 and 12. of the re ceptacle are provided with-a pair of horizontal longitudinal ledges 13 upon which rests a grate 14, said grate being made out of a single rod formed into rectangular convolutions, the ends of said convolutions being adapted to rest on the ledges 13 as illus trated in Fig. 1 from the receptacle as also are the legs, so

cleaned from time .to time. A removable -cover B is provided on the receptacle, which,

can be securely closed thereover by means of the studs 15 on the ends 16 of the receptacle, which are adapted to be sprung into engagement with the cover through 0 en'- ings 17 in the ends 18 of the cover, (seeig. 3); When the stove is in use and'the cover removed, the cover can be inverted and used asa tray to support the extended legs of the receptacle.

Disposed within the receptacle is a burner fixture C-formed with supports 20, which are rigidly secured to the bottom 2 of the recep-- The burner fixture is in the form of a duct 22 having uptacle by rivets or bolts 21.

turned ends 23 and 24. The ends 23 and 24 are formed with horizontal burner bases 25- This grate is separable i that the parts can be separated and easily and 26, of burners D and E, resembling disk or circular plates. A burner cap on base member 25 is in the form of a ring member 27 'having radiating ribs 28 on its lower surface and radiating ribs .29 on itsupper surface forming channels through which gas from the duct 22 may pass outwardly. Secured over the ring 27 is a. burner cap 29, which is formed by a plate having a shallow centrally disposed cup 30, in which gasolene or other hydrocarbon liquid may be placed and ignited for heating the burner'to start the generation of gas. The outer peripheral edges ofthe cap piece 29 and the base member 25 are formed with inturned shoulders 31 which act as deflectors to direct the flow of gas through the channels between the ribs 28 and 29 and commingle the constituent parts of the gas to form an efi'ective gaseous fuel medium. The 'cap member 29 is secured on the ring member 27 and to the base member 25 to hold said parts together by means of the screws 32. The burner E on the upturned end 24 of duct 22' issimilar in construction to the parts of the burner D just described, excepting that the cap piece 33 is secured over the ring member 34 and to the base member 26 by a single screw 35.

The supply of fuel mixture to the burner E is controlled b a valve 36, which is ada ted to seat at 37 1n the duct and is provi ed with threaded valve stem38 having a key 39 slidably mounted thereon, said key being joined to the valve stem 38 by a lug and slot connection 40, whereby the key 39 may be extended or receded through an opening 41 in the end of the receptacle A, sald key bein extended when it is desired to turn the va ve and open or close the same. The valve stem 38 is threaded in a stopper 41. in one end ofthe duct.

Fuel mixture is admitted into the duct nection i or' stopper 44 being provided through which the tank can be filled and air pressure applied by, means of the pump 45 or other suitable means. A suitable supply nozzle is secured and connected with the tank by the threaded coupling 46, said 4 nozzle bein provided with a gas generating tube 47, w 'ch has a coupling member 48 onits outer end, said coupling member being adapted to be detachably secured in the upper end of branch member F and connected with the duct therein to supply the hydrocarbon mixture from the supply tank to the burners. The point at which the coupling 48 is attached to the branch F is disposed so that the generating tube 47 will extend across and immediately above the burner D, whereby heat from the burner either supplied by the burning gases from the fuel in the cup'3O or from the burner proper will start and continue the generation of gas in the tube before it is admitted into the duct C. The supply nozzle H has threaded therein the stem 49 of a valve 50,

which is seated in the coupling member 48.

The valve stem is threaded in the nozzle member H and extends outwardly therefrom being provided with a handle 51 by which itcan be turned. The nozzle member passes through an opening 52 in one of vent the supply tank from being unintentionally detached from the burner fixture when in use. It will be noted that the burner cap 29 is provided with the usual perforations immediately below the gas generating tube 47, through-which some ofthe gas may pass to produce a heating flame below, and in contact with the generator tube to heat the latter,

In use, assuming the stove to be folded, the cover is first removed and the legs extended and locked in extended position and. then placed with their lower ends upon the inverted cover. The supply tank after being removed from the receptacle is inflated by pumping air into it and is secured by its generating tube to the receptacle. A small amount of gasolene is then placed in the cups of the burners and ignited. After the burners and generating tube have been heated by burning the gasolene in the cups the valve 50is opened by turning the handle 51. The gas generated by the generating tube is thus admitted into the duct from whence it asses outwardly through the burners and is ignited. The resulting flames continue the generation of gas in the burner tube and in the duct, and as a result an emcient heater is provided for cooking and heating purposes by the burners. When desired onlyone burner need be operated, the valve 36 being provided for cutting 0d the supply of gas to the burner E. The parts of the device can easily and quickly be set forth within the scope of the following claims.

Having described my invention, what I claim as new and desire to protect by Let-.

ters Patent is a 1.
