VAPOR-STOVE.

This invention relates to kerosene burning stoves, and the primary object of my ln'vention'is to provlde a novel burner wlnch will permit of kerosene being utilized as a fuel, and novel means is employed for vaporizing the kerosene so that it may commingle with air and readily burn at a burner. v

A furtherobject of my invention is to provide a gas generating apparatus that may be attached to various types of stoves,

for generating a vapor which will burn with a flame of high calorlc value and the construction of the generator is such that it may be safely used. c

A still further object of my invention is to provide a stove burner with means for supplying fuel thereto, wherein the parts are constructed with a view of reducing the cost of manufacture and at the same time retain those features by which durability,

- simplicity of construction, and ease of assembling are secured. WVith such ends in View, :my invention resides in the novel construction, combination and'arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be hadto the drawing, wherein- Figure 1 is a plan of a range provided with burners in accordance with my invention; v r

Fig. 2 is a longitudinal sectional view of one of the burners, on a large scale and taken on or about line 2-2 of Fig. 1;

Fig. 3 is a vertical sectional view ofa heating stove in accordance with my invention;

*ig. 4 is an enlarged sectional view of the burner of the stove;

Fig. 5 isa side elevation of the burner of the stove being utilized in connection with a small cook stove;

Fig. 6 is an enlarged cross sectional view 7 of the fuel tank;

Fig. 8 is a side elevation. of a portion of the needle valve, and

Fig. 9 is a plan of a detached flame deflector that may be used on the burner.

Reference will first be had to Figs. 1 and 2 showing the manner of using burners as a part of a gas plate or range 1 which has a plurality of grids 2. Below each grid is a burner in communication with a supply pipe 3 connected by a coil 4 to a fuel tank 5 containing kerosene or similar fuel. The tank 5 may be supported conveniently at the end of the range 1 vby straps 5 encircling the fuel tank and connected to the end of a range and said tank has one end thereof connected by a pipe 6 toa manually operated air pump 7 mounted on the tank 5, said pump being used to force air into the tank 5 so that the contents thereof will be normally under pressure suiiicient to force the kerosene laden air into the supply pipe 3 and to the burners connected thereto.

The tank 5 has a filling opening 8 which is normally closed by a cap or other closure member and on top of said tank is a conventional form of safety valve 9 which may be adjusted so that an excessive quantity of air within the tank 5 may escape to the atmosphere and thus prevent the tank 5 from being overcharged. Adjacent the tank is also a shut off valve 10 for the coil at and this shut off valve permits of all of the burners being rendered inactive and the fuel retained within the tank 5 independent of any other valve.

Considering one of the burners, as shown in Fig. 2, a T connection or body 11 is employed and provided with reduced ends 12 and 13, the former forming an annular shoulder 1% on which may be mounted a nipple is a tapering outlet port 18 for a fine needle 18 of a needle valve'19 disposed longitudinally of the T body 11 and entered therein through the reduced end 13 of said T body which is normally closed by a cab 20. The lower end of the needle valve 19' is comparatively flat so that its side edges may slide in opposed grooves 11 provided therefor in the reduced end 13 of the T body 11 and prevent rotative movement of theneedle valve. The flat portion of the needle valve is slotted, as at 21, and one of the walls of the slot provided with a rack 22 for a pinion 23 which extends into'the slot 21. The pinion 23 is on the inner end of a rod 24 which has its inner end journaled in a wall of the T body 11 and its outer end extending through a pipe 25 connected to the T body l l and provided with an angle connection 26 having a stufling box 27 through which the rod 24 extends, said rod having a suitable hand wheel 28 so that the rod may be rotated to adjust the needle valve 19 through the medium of the rack .22 V and the pinion 23. The rod 24 has a reduced end portion 24? into which extends a set V screw 25*, carried by the angle connection '26,'and this set screw prevents longitudinal displacement of the rod 24 and permits of said rod being removed. The angle connection 26 is included in the fuel supply pipe 3 andadjacent each angle connection of said pipe there is a-shut off valve 29, which controls the supply of fuel from the pipe3 to.

the angle connection 26 and thus permits of the burners of the range 1 being used independent of each other.

Reference will now'be had to Figs. 3, 4 and 5 showing a burner, generally desig- .nated 34 as. being connected direct to the top of a fuel tank 35, which is preferably in the form of the lamp body having legs 36 so that it may be supported on the floor or in the base portion of the stove 38. The burner 34, and the supply pipe 3, have portions 35 and 3 respectively extending in proximity to the bottoms of the tanks 35 and 5, so that practically the entire contents ofv said tanksmay be used. The burner 34 is similar to the burner shown in Fig. 2, and extending into the tank 35 is an angularly disposed air pump 39 which permits of the a tank being charged with air, and besides this pump there is a safety valve 40 and a filling opening or connection 41. The legs 36 of the tank 35 extend upwardly at the side walls of the tank, as best shown in Fig. 5 and afford sockets for uprights 42 adapted to-support an oven or, any

and when it is desired to use the burner for heating purposes, the tank 35 may be-transferred to the stove 38 which has its side walls provided with suitable openings so that the burner regulating rod 24 may protrude from the stove 38 to be conveniently adjusted. The safety valve 40 may also be regulated from without the stove 38.

Occasions or use may require the flame at the distributer 17 of the burner to be more or less mufiied and to accomplish this I provide the distributer 17 with a centrally apertured cap 44 over which is placed a foraminous cap 45, These caps will cotiperate in retarding the flame of the burner so that allproducts ofv combustion maybe consumed, and to confine the flame at the upper end of the burner and at the same time permit of-sufiicient air reachingthe distributer 17, a cylindrical apertured guard 46 may be placed on the tank 35 about the burner 34.

There are instances when the guard 46 and Y the caps 44 and 45 willnot be used, but when the burneris used any place where there may be a colddraft, then it is preferable to install the guard 46.

A flame deflector-"48, as shown in Fig. 9,

.may be placed on the flame'distributer 17,

particularly when the burner is used for cooking purposes and the pan, plate or other member is supported above the'burner in place of the oven 43.

In placing air in the tank 5 or .35 under v pressure, the air is caused to agitate the kerosene or fuel therein to that extent that the air is saturated with kerosene and in the form of a combustible vapor which may be ignited at the distributers of the burners and its use controlled bythe needle valve in said burners. H While in the drawings there are illustratec the preferred embodiments of myinvention, it-is to be understood that the structural elements are susceptible to such variations and V modifications as fall within the scope of the appended claim.

What I claim is A burner comprising a T body having a lateral liquid fuel receiving connection, said body having reduced ends, a nipple on the upperv reduced end of said body, said body having guide grooves in the lower reduced end thereof, a cap closing the lower reduced end of said body, a needle valve in said bOClY'IHOVELblG tO and from said nipple and having a slotted rack portion'slidable in the guide grooves of said body, a basin on the upperreduced end' of said body and retained thereon by said nipple, a flame distributer on said nipple, a rotatable rod ex- In testimony whereof I afiix my signature in the presence of two Witnesses.
