GASOLINE CAMP STO'VE.

Application lled October 21, 1921. Serial No. 509,396.

To all whom t may concern.'

Be it known that we, Louis B. GOLDBERG, NATHAN GOLDBERG, JACOB M. GOLDBERG, and

WILLIAM GOLDBERG, citizens of the United States, residing at the city and county of Denver', State of Colorado, have invented certain new and useful Improvements in Gasoline Camp Stoves, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, which form a art hereof.

The dbject of the invention is to provide a durable and efficient portable camp stove, which shall be comparatively simple and cheap to manufacture.

This application is a continuation in part of our application, Serial No. 503,352, filed September 26, 1921. n

The stove comprises a casing wherein the burners are mounted, the burners being supplied with liquid fuel from a small pressure tank.k More particularly, the invention re sides in the burner and manifold construction. Air is received in regulated quantities into the manifold through a downwardly directed port which prevents material interference with the fuel mixture by a strong breeze or lateral draft. The burners include a spreader plate and spaced thereabove a guard plate which prevents the flame from being easily blown out. rlhese plates rest upon the walls of the body or cup of the burner, and the said walls are provided with lugs which directly support the grates of the burners. A vaporizing cup is provided adjacent the manifold so as to heat a tube leading from the pressure tank, and each grate is also provided with a vaporizing cup. Preferably the primary burner underlies said tube so as to heat the same during opf eration. Inthe secondary or remote burner a cylindrical bore is provided whose axis is perpendicular to the bottom of the burner,

and a curved plate having a guide tongue movable 1n a guide slot is adjustable toward and from said axis and a wall of said bore to control the supply of fuel to the respective burner.

Fig. 9 is a cross section showing a latch for retaining a cover;

Fig. 10 is an elevational detail taken from line 10-10 of Fig. 4.

A casing 10 houses the burners and is provided with a work plate or table 12 having a row of ventilating and cooling apertures 112 spaced from the burners, said plate being hinged to the casing at 14 and being cut out to receive the burner grates at 15. Supporting brackets 16 (Figs. 1 and 9) are mounted on the casing for engagement by the forward end of plate 12. A fuel pipe 18 leading from a small pressure tank 19 and controlled by a valve 20, leads across the primary burner to and into an opening 21 in a manifold 22 between the burners. Manifold 22 has therewithin a mixing chamber 211 receiving air through a downwardly directed inlet port 125 formed by a laterally offset lip 25 on'tlie side of the manifold. The manifold communicates with a fuel duct 26 leading to the burner cup 28 of each burner. Each burner 28 has a central threaded hub 30 extending upward from the bottom thereof and this hub supports a spreader plate 32 having a series of radiating rows of apertures 33. A guard plate 34C rests upon the walls of the cup, this'plate being provided with a series of radiating slots 85 staggered vertically with relation to the aperture-rows 33, and having a depending positioning flange 36 engaging the outer walls of the cup.

, kThe outer walls of each cup 28 are provided with lugs 38, and a vaporizing cup 40 is placed between the primary burner and the manifold 22 fork the purpose of receiving a quantity of fuel to heat up the tube 18 and adjacent parts when starting the burnen r A grate 12 is supported above each burner by means of integral legs 44 resting upon the lugs 38, the grate being formed ot adiating bars and an annular member 115. The middle or ea h grate is in the torni of a priming or vaporizing cup 48 to receive liquid iuel initially tor speeding up the starting operation, and this cup d8 is slotted for a part ot the way to its bottom as indicated at 50 to receive the tube 1S. rlhe bottom of cup -18 rests in a depression in the guard plate 311 and a screw 52' (Fig. 5) passes through the said bottoni and the plates 82 and 34 and is `threaded .into the hub 30, the screw thus retaining' the parts in operative relation. lt desired one ot the legs 1111 .may rest on the edge of cup il@ and one of the lugs 38 on the primary burner be eliminated.

ln the case ot' the secondary or remote burner, the vapor duct leads to a point on the outer side thereof which is beyond the respective hub 30, so that the flow oi fuel may be controlled by a valve operable from the outside of the casing 10. Said valve is in the torni oic a curved plate 55 which engages and lits against a portion of the cylindrical surface ci" a cylindrical bore as indicated at 5d (Fig. 7), the axis of this bore being perpendicular to the bottom of the burner. A tongue 56 on the lower edge ot the plate 55 runs in a guide groove 5S in the bottom of the burner and thus maintains the position of the plate. An operating stem G2, which is threaded in the wall of the burner at GO, has its inner end connected with plate 'tor reciprocation ot the latter, while its outer end extends through casing l() and is provided with an operating disc (Se, said disc being guarded by a relatively narrow strap (S5 secured to the casing as at 66.

ln order to control the flow ot' air to the mixing chamber 2st, a damper or valve 70 is provided to cover the opening 125 under lip 25. ln the forni shown, this valve swings on a pivot 71 threaded into the end of vaporizing cup l0, and a manipulating rod 72, having an upturned end 'le directly engaging the valve, leads forward to the front olf' the casing 10 where its end is accessible. rlhis valve is particularly valuable in cas(` oit z. strong breeze, or when the pressure in the tank 19 is high and it is desired to turn the flame low; in this instance, the valve is partially or entirely closed to reduce the flow of air, and popping out ot the flame is avoided. The flow of fuel to the secondar7 burner is also controllable independently of the other burner by valve plate 55, and the construction shown affords a simple and cheap means for such control. rlhe two plates 82 and 341 alford an excellent control for the fuel gas at the point of combustion, and this is particularly assisted by the staggered relation ot rows of apertures 83 and slots 35. .Plate 32 spreads the mixture and plate Se prevents material disturbance thereoit in the space between the plates when a breeze is blowing, thus etfectually preventing blowing out ot the iiame by a moderate breeze. rlhe hub or the grate further protests the Haine on the leeward side.

Burning liquid fuel in the vaporizing cup 11G not only heats up the tube'18 to Vaporizing point but also heats up the manifold 22. Further heating ot tube 22 may be had if necessary byburning liquid fuel in cup 48 oi" the primary burner grate. The downwardly directed opening' ot' the intake 125 avoids interference with the current of air by a breeze, because the breeze moves laterally and the natural draft is upward.

The plate 12 serves as a support for veswhich are not desired to be directly over the flame. rl`he space under said plate and i'forward ot the burners is utilized for carthe tank 19 when not in use. A cover 8O which may be hinged to the back of the casing 10 at 81 is provided with the secure latch 82 shown in Fig. 9. The tip of this latch, which is hook shaped, enters an aperture in the casing wall at 83, while the body thereoic which lies on top of the cover 8O is guided by a loop or the like 84 secured to the cover. A spring S5 is secured to the rear end oit the latch 82 and is lixed to a lug 86 on the cover. 1n this manner spring 85 always retains the latch in engagement with aperture 83 in the casing, thus preventing accident-al opening of the cover. At the saine time the latch may be readily released by withdrawing the saine against the tension of the spring. As seen in Fig. 1, legs l? may be provided for support of the stove it the same are desired, and inasmuch as the draft to the burners is had chieliy through apertures (c in the bottom ot the casing use ot said legs would be preferable.
