w. GOLDBERG ET AL CAMP STOVE Filed August 7, 1925 2 Sheets-Sheet 1 Dec. 28 1926.

w. GOLDBERG ET AL CAMP STOVE 2 Sheets-Sheet 2 cylindrical tank 19 from Which the tubular conduit 20 extends. This conduit or tube projects into an opening in the cylindrical portion 21 of the valve 13 and a tight joint is made between the two by means of a gland 22 which can be held in adjusted position by means of a set screw 23. A bracket 24 is secured to the end 6 by means of screws 25 and has a portion that embraces the pipe 20 so as to form a bearing in Which the pipe may rotate when the tank is moved from the full line position to the dotted line position (Fig. 1). It is noW apparent that the tank 19 is always connected with the valve 13 by means which permits it to be rotated about the axes of the member 21 into and out of the casing without, however, being detached from the casing. Tank 19 is provided with an air pump 26 by means of which the liquid contents of the tank can be subjected t0 air pressure. Secured to one side of the tank 19 is a priming device consisting of a valve 27 (Fig. 4;) interposed in a pipe 28 that extends from the interior of the tank t0 a point above the priming cup 17. VVhen the valve 27 is moved to open position, gasoline Will fiow through the pipe 28 into the priming cup. After the p1iming cup has been filled With gasoline, the tank is swung outwardly to the dotted line position in Fig. 1 or to the position shown in full lines in Fig. 10. The gasoline in the cup 17 is then ignited and the fiance heats the tube 16. iVhen the tube 16 has been thoroughly heated, the handle 18 is rotated so as to open the valve 13; this permits gasoline to fiow into the generator tube 16 where it is converted into vapor and passes into the manifold thence to the burners. The flame from the burning gases keeps the generator tube 16 hot so that it Will vaporize the gasoiine and produce a constant floW of gas. Oxving to the fact that the generat0r tube is empty when it is first heated, there Will be no gasoline forced into the manifold and therefore there Will be no burst of flame when the st0ve is ignited, Which is the case when the tank and generat0r are made detachable and the priming is clone through the generator tube. V7e desire to call attention to the fact that the priming device need not necessarily be connected directly to the tank but may be connected at any point between the tank and the valve 13, it being merely necessary that the priming can be clone without introducing gasoline into the generator tube as this produces the objectionable results above referred to.

In Fig. 5 we have shown a slightly modified construction in which a valve 29 is located between the tank and the packing gland 23. The purpose of this extra valve is to prevent pressure on the swivel joint when the stove is not n use, and thereby prevent the possiblhty of leakage. VVhen the extra valve 29 is employed, the admission of gasoline may be controlled by it to such an extent that the swivel joint is sub jected to very lit-le pressure at anv time and the valve stem operated by the handle 18 may be empl0yed merely to control the flow of gas from the generacor. V\hen 0H1 stove is not in use the tank 19 occupies the position shown in full lines in Fig. 1. As the stove is intended primarfly for use by campers and automobile tourists, it must be so constructed that the parts are protected against damage from 1ough usage. Ve have chercfore provided means for guarding the valve 13 and associated parts against damage.

This means comprises a box-1ike housing 30 whose ends 31 and 32 have pe1f0rated ears 33 that receive the ends 34; of the legs 35 which serve as pivots about Which the box swings. upper edge of the box 30 at 37. Nben the tank is in place within the casing, the box 30 is swung about its pivots 3 1 into the position shown in Figs. 1 t0 5. The cover 36 is provided with a roll 38 that is adapted to be engaged by the roll 39 on the cover 9 (Figs. 2 and 3) so as to hold the box 31 in place about the parts that it is designed to protect. When the stove is in use, the protective box, or enclosure 30, is released and dropped clown out of the vvay.

In Figures 7 and 8, We have shown the end closure 30 constructed in a slightly dif- -ferent manner. Instead of the sides having cars 33 that are pivoted on the ends 34 of the legs 35, the sides 31 and 32 are smaller and are not provided with ears like sides 31 and 32. The curved side 30 has a downwardly extending part 40 that is rolled at 41 about the wire 42 that serves as a hinge pin. 'By this construction the closure can be swung into the dotted line position shown in Fig. 8.

It Will'be seen from the above that we. have produced a st0ve in which the genrator tube is attached to the casing and to the manifold and is intended to be removed only for cleaning or repairng. The tank, instead of being rigidly attached to the generat0r, is connected thereto by a swivelled connecti0n that makes it possible to swing the tank out of inoperative position (full line position'Fig. 1) to operative position (full line position in Fig. 9) or vice versa without disconnecting it from the generator. W e have provided means for priming Which is entirely independent of the generator tube with the result that a more desirable operation is assured.

Having described our invention what we daim as new is:

A camp stove comprisimg, in combination, a casing having, a bott0m, two sides and two end walls, a burner located Within said casing, a manifold, a generator tube extend- A cover member 36 is binged to the ing across one of the end walls and over the burner one and of said generator projecting into the manifold, a right angle connector secured to the outer and of the generator, a valve mechansm in said connecter, one and 01" said connecter beng provided with a stuffing box whose axis extends parallel with the end wal1, a fuel tank, a pipe having one and connected to the tank and the other rotatably connected to the connecter, a bracket Secu1ed to'the end wall, said brackct having a bearing for the pipe, said tank being rotatable about t1 1e axis of said pipe into and out of said cas1ng and means for enclosng the connector and pipe when the tank is 15 within the casing.

In testimony whereof we afiix OUI signatures.
