Application flledMarch 19, 1928. Serial No. 262,770.

This invention relates to improvements in gasoline stoves of the type sometimes referred to as camp stoves.

Owing to the great prevalence of camping by hunters, fishermen and tourists, a type of gasoline stove has been developed which is especially well adapted for use by campers, as it can be folded very compactly and can therefore'be readily packed and transported and as the fuel employed is gasoline, the stove can be put into operative condition very quickly. Stoves of this type are often subjected to rough usage during transportation and it is therefore necessary that the burner, the gasoline tank and thegenerator tube shall be Well protected against injury and at the same time it is necessary that the gasoline tank be placed in a position outside of the casing during the time that thestove is in use, so as to expose it to the circulation of the air and protect it as much as possible from the heat generated b the burners.

It is the object of this invention to produce a gasoline stove of the type referred'to which shall be so constructed that when the stove is not in use, the burner and the gasoline tank will be located inside of the casing so as to be protected and which can be readily moved to operative position when the stove is to be use v The stove which forms the subject of this invention can be most clearly described and readily understood when reference is had to i the accompanying drawings in -which the preferred embodiment thereof has beenfillus-' trated, and in which:

Fig.1 is a top plan view'of a stove showing:

the parts in operative position Fig. 2 is a top plan View showing the parts inthe position which they occupy durmgtransportation; i

Fig. 3 is a'section taken on line 3 -3, Fig' 1 Fig; 4 is a section taken on line 4 1, Fig. 2 Fig; 5 is a top plan view of a fragmentary portion of a'stove constructed in a slightly different manner; and

Fig. 6 isa section taken on line 66, Fig. 5.

The stove" which forms the subject of this invention is provided withv a sheet metal casing havingfend walls 1, 2, sidewalls 3, 4 and a cover. 5. A grate 6 is also hinged toone edge of the casing, but fasthe particular construction of the gratehas nothing to do with the present invention, only a portion of the grate .has been shown' Located within of spaced'st-raps 17 and can be rotated about fore the burner assembly which is secured .30 and 31.

the casing and secured to the bottom 7 thereof, is a burner assembly comprising two burners 8 and 9, which areattached to opposite ends of the manifold 10. This manifold has a mixing chamber 11, to which reference will hereinafter be made. The manifold is provided with two downwardly extending v I lugs 12, to which a h'inge member 13 is secured by means of screws or rivets 14'; This hinge member extends a considerable dis,- tance to one side of, the manifold in the manner shown in Fig. 3 and is provided with a curved portion15, that encloses the rod 16. This rod is secured to the bottom? by means its axis and since the straps 17 are placed" a shorter distance'apart than the ends of the hinge members 13, it is also possible to slide the rod 16 longitudinally and thereto rod 16 can be moved longitudinally of Y the casing and can also be rotated about the axis of rod 16'from the position shown in Fig. 3 to the position shown in Fig. 4. Attached to burner 9 is a bracket 18 whose upper end is provided with an opening for the reception of a pin 19 and secured to the burner 8 is a bracket 20, which is constructed in the manner shown in Fig. 2. Bracket 20 has openings through which the generator tube 21 may extend.- A tank 22 is provided for the storage of gasoline and secured to one end of this tank is a strap 23 whose other end is provided with an opening throughwhich ;a pivot. Extending from the other end of the tank is a pipe '24c, one end of'which is connectedwith the valve member 25" at 26. Valve operating member 27 is provided with a knurled head 28, by means of which it can "be, rotated. The generator tube 21 is connccted to the outlet end 29 of the valve'25, and by rotating the valve controlling nember 27, gasoline will be permitted to flow from the tank 22' through the generating tube end into the mixing chamber 11 or pre vented from flowing 'as may be desired. Strap 23 has been shown as attached to the tank 22 by means of two clamping members These clamping members are provided with radially extending arms32 and 33 which embrace 1 the outer end} of the strap 23-and are secured together bymeans of a bolt 34. The other'ends of the clamping 1 members extend tangentially in the manner indicated by reference numerals 35 and 36, Parts 35 and 36 are secured together by means of a rivet 37 and part 35 extends somewhat farther than the part 37 and is provided with a short downwardly extending end portion 38, while part 36 has a similar downwardly extending portion 39. Side l of the casing has an opening 40 through which the end of member 35 extends in the manner shown in Fig. 1 and which serves-to hold the tank in i but merely acts as a tension member which 9 transportation.

connects the tank with the pin 19, and therefore the weight of the tank is supported on the tangentially extending part in the manner shown in Fig. 3. This construction has been found to be very satisfactory for the reason that the tension thus produced in strap 23 tends to hold the burners in the position shown in Fig. 3, whereas if strap 23 rested on the upper edge of side 4:, a slight accidental bending of this strap would have a tendency to destroy the proper adjustments of the burner and the latter would therefore frequently be held in a position in which the end 43 of the hinge member 13 would not rest on the bottom 7 as it should.

lVhen the stove is in operative position, the

burners should be located on a line extending through the center of the casing and burners 8 and 9 should be spaced equal distances from their corresponding end members. It

'is apparent, however, that in order to get the tank 22, pipe 24: and operating member 28 within the casing, 1t is necessary to move the entire assemly towards end 1 and this is ac:

oomplished in the following manner. Starting with the parts in the position shown in 'Fig. 1, the operating handle 4st is moved hi .wardly through slot so as to extend substantially perpendicular to the rod 46. The

tank 22 is now rotated about the axis of pin 19 and of the generator tube 21 into a vertical position and the entire assembly is then moved towards end member 1, the pipe 24:

passing through the slot 47. After the head 28' has been positioned inside of end 2, the burner assembly is rotated about the axis of rod 16 from the position shown in Fig. 3 to that shown in Fig. 4 and the tank 22 is then moved downwardly until the ends 38 and 39 rest on the bottom 7 in the manner shown in Fig. 4; The grate 6 and the cover 5 can;

is ready tor p l g permitsan operatlonthat is very similarto then be closed and the stove Attention is called at this point to the fact that with the construction above described, the tank and generator tube are always secured to the burner assembly so that the parts are always in properly adjusted position. If, however, it should be'necessary to detach the tank for any purpose, this can readily be accomplished'by removing the pin 19 when the generator tube 21 can be withdrawn from the bracket 20 in a mannerjquite obvious from the drawings.

Attention is also called to the fact that the burner assembly can be movedlongitudinally of the casing and then rotated about an axis parallel with the longitudinal sides of the casing and this construction permits the parts to be very quickly moved from inoperative to operative positionand therefore provide a very convenient arrangement for stoves of this kind. V

' In Figs. 5 and6, a slightly modified con struction has been shown. In this, construction the rod .16 has been dispensed with and in lieu thereo'ttwo special hinges have been provided, each hinge consists of three members 48, 4-9 and 50., Members 48 are secured to the bottom 7 by means of rivets 5liand are connected to members 49' by means of a hinge comprising a hinge pin 52. It will be observed that member 4.9 is of angular construeburner assembly comprising the manifold 10 and burners 8 and 9 can be moved longitudinally of the casing by a circular motion about the hinge pins 53. By raising-the burner assembl and movin it towards the Y e right, members 5O can be rotated through an arc of substantially onehundred eighty degrees from the full line position to the dotted line position shown in Fig. 5. "This move ment is the equivalent of the sliding movement above described andpermits the pipe 24: and the knurled head 28 to be moved from a position in which they lie outside of the casing'like shown in Fig. 1,-to a position in which they lie within the casing. After the burner assembly has been moved to the right in the manner described, it can then be rotated about hinge pins 52 to the position shown in Fig. 6. Thislast movement is equivalent to the rotation about the axis of rod 16 and moves theparts towards the side 3 a suliicient distance topermit the tank to be placed inside of the casing somewhat in the manner shown in Fig. 4c. j

The construction shown in Figs. 5 and 6 the operation permitted b the construction shown in Figs. 1 to 4. longitudinal movement of the burner assembly, which is of suflicient extent or value to move the parts towards the right, a sufficient distance to bring the valve opera-ting member 28 within the casing and there is then a transverse movement which includes a rotation about a longitudinal axis so as to move the parts towards the rear of the casing a sufiicient distance to permit'the tank to be brought into position within the latter.

From Figs. 1 and 2 it will be seen that when the parts are in operative position (Fig. 1) pipe 24 and valve '25 are on the outside of the casing and are therefore shielded from the heat by the interposition of the end 2. It is, of course, possible to dispense with the longitudinal movement by which pipe 24 is moved from one side of end 2 to the other side and when this is done pipe 24 will always remain on the inside ofthe casing which is not as. desirable as the arrangement shown.

been achieved which permits the tank and attaching means to be quickly disposed within the casing for transportation and which permits them to be moved to operating posi-.

tion with equal facility.-

Attention is also called to the important fact that the'burner assembly is always attached to the bottom of the casing and that the tank is connected with the burner assembly so that the user of the stove will not be called upon to connect and disconnect the parts in arranging them for use or for transportation.
