This invention relates to improvements in is to provide the housing of the distributing hydrocarbon stoves and burners therefor and has relation to that ty e of stove in which the liquid fuel supplyjs orced by pressure to a generator from" which it is supplied to a burner or burners where it is lighted.

An object of'the present invention is to provide a generator that is located within a main burner whereby the generator when 1t is once started is kept heated by a flame in the main burner whereby the vapor is necessary for operating the burner, and other burners is supplied. 7

Another object of the present invention is to conceal within the main burner a generator whereby when it is one started the heat from a flame in the main burner keeps the generator hot for supplying va or to the main burner and from the main urner to additional burners.

Another object of my present invention is to provide a distributing chamber with a generator concealed therein, the main burner having a mixing chamber extending to one side thereof and in communication with the distributing chamber whereby the enerator supplies vapor to the mixing cha'm er from which it flows into the distributing chamber for supplying a flame that continues to keep the generator hot and supplies additional vapor to other burners which are connected with the main burner.

A further object of the present invention is to provide the housing for the distributing chamber and the main burner having an upwardly extending transversely arranged generator receiving chamber that has an open bottom with an outlet at the top whereby the generator is heated from below and is kept heated by the heat from a flame in the main burner for supplying vapor for the main burner and additional burners.

A further object of the present invention is to )rovide the housing of the distributing cham er with an inverted U-shapd chamber extending across the same in which chamber is located a generator and located below the generator is a heating device adapted to receive a torch for heating the generator, the generator being kept hot by the .flanie supplied from the distributing chamber and the main burner when it has once been heated.

A further object of the present invention chamber with an inverted U-sha ed chamber extending transverse thereo the said chamber having open ends and bottom and adapted to receive a generator, and to ro- 'vide the wall of the main burner wit a mixing chamber having its inner end open and in communication with the U-sha ed chamber, the outer end of the chamber oubling back and in communication with the distributing chamber, whereby vapor passing into the chamber carries with it air that is mixed and forms a combustible gas for all of the burners.

Another object of the present invention is to provide a housing, the bottom of the housing having an inverted U-shaped chamber in which is placed a enerator, the said chamber having an en ottom and an 0 en end for the outlet 0 the generator, an to rovide the wall of the housing with a mixmg chamber comprising a center portion and two parallel side portions, the center portion bein in communication with the generator an the two side portions in communication with a distributing chamber at o posite sides of the inverted "U-shaped c amber.

A further object of the present invention is to provide a housing with a generator, and having lateral pipes connecting with addi tional burners whereby more vapor is supplied than is necessary for the main burner, the surplus vapor flowing into the additional burners, and controlling the flow of vapor into the additional burner by a valve or valves located in the additional burner or burners.

Referring now to the drawings in which 1 indicates a suitable frame for the parts comprising the present'invention. Located in the frame 1 about midway the height thereof is a horizontal fuel supply tank 2, the .said tank extending within the frame of the stove, and its outer end projecting beyond the end 3 whereby it is readily accessible. The tank 2 has at its extended end a communication 4 having a suitable ball valve 5 held to its seat by air pressure within the tank 2. The tank is supplied with oil and then the pump 7 placedover the nipple 10 which has communication with the passage 9 of the connection 4 and then working the plunger 8 in the ordinary manner forces air past the ball valve 5 into the tank 2. The oil container in the tank isthen under pressure and flows from the tank through the pipe 11 to the pipe 12 andthen into the generator 13. A valve 14 is preferably placed at the junction of the pipe 12 with the pipe 11 which controls the pressure'fed from the tank 2 to the burner.

Referring to Figure 2 in which 15 is the main burner and16 are two additional burn- 'ers that are connected with the distributing chamber located at the lower part of the housing by suitable pipes 17. The vertical ner-1,854

wall 18 forms a vertical housing and the bottom -19 of the housing is provided with an inverted U-shaped chamber 20 for the reception of the generator 13. This inverted the vapor and air mixing chambers. By the time the vapor has reached the inner outlet ends 26 of the passageways the air and vapor are thoroughly mixed and form a combustible composition for burning purposes.

The generator 13 is placed in the inverted U-shaped chamber 20 and its nozzle end 23 passes through and rests on a support 27 thus holding the nozzle end in position while its inlet end 28 is held in position by a suitable cotter pin 29 that passes through ears 30 that extend outward from the side wall 18 of the main burner. This makes the generator readily separable for any purpose whateVeL.

The generator preferably is rectangular in cross section as shown in Figure 8, and consists of a tubular construction. The nozzle 23 is detachable from the inner end of the tubular portion 13 for purposes of convenience in manufacture and cleaning. The valve stem 31 is elongated and passes through the tubular portion 13 and carries at .its outer end a suitable pin 32 which passes through the outlet 33 for the purpose of cleaning it of accumulated carbon. Placed around the valve stem 31 and preferably snugly fitting it is a spiral wire 34 the outer periphery of the wire also snugly fitting the opening 35 of the tubular member., The outer end 28 of the generator has an oil inlet 36 with which the outlet end of the pipe 12 is connected. The inlet end of the generator also has an additional outwardly projecting tubular portion 37 which receives the outer end of the valvestem. This outer portion of the valve stem is screw-threaded as at 38 and meshing withinternal screw threads formed on the member 37 the outer end of the valve having any desired form of hand operating member 39 rotating it.

, Attention is called to the fact that the valve stem is provided with a valve 40 located at the-oil inlet 36. This is the only valve that the valve stem contains and it is by means of this valve, and this valve alone that the passage of vapor is controlled ,from the generator to the main burner for maintaining the desired height of flame. It will be observed that this valve 40 engages the seat 41, and controls the flow of oil to the inlet end of the generator tube 113, and in that way controls the vapor generated.

The valve stem has at the outer end of the threaded portion 38, a suitable member 44.- wliich is held against longitudinal movement thereon preferably by a projection 45 extending from the valve stem. A suitable ring 46 is located at the outer end of the member 44 for the purpose of engaging the packing 47 when the valve is ;opened as shown in Figure]. This arrangement prevents the valve from being entirely screwed out of its tubular portion 37. It prevents anyone from detaching this valve from the burner thus causing possibly an accident. The object of the ring 46 is that the ring will remain stationary when it'reaches the packing 47 so that wear on the packing does not happen. With the valve entirely wide open so that all the burners are burning full this ring will prevent any oil findin its'way out-as will be readily understoo Located below the main burner 15 is an initial hegting device 50. This device is for the purpose of receiving a torch member 51. The device is in the form ,of a chamber that has a bottom 52 and at each side of the bottom are longitudinal slits 53. A perforated member 54 is located between the bottom 52 and the top 55, the said construction forming an outlet opening 56. This device is suprted to a web 57 extending downward rom the nozzle receiving member 27 by a suitable screw or screws 58passing through it into the end of the member 50.

A torch holding member 59 is attached to the end of the stove and it consists essentially of an outer casing containing an inverted member 60, preferably of glass, the

cap 61 having a spring actuated valve mem ber 62 whereby when the bottom is placed in position the valve is unseated and gasoline flows into the member 59 and through an opening 63 into the torch receiving part 64. By this means the torch is always saturated ready to be lighted in the manner presently described. \Vhen the torch is in position the whole device is sealed so that there cannot be accident by fire.

The generator 13 is to provide suflicient vapor for the main burner 15 and additional burners 16. Therefore it is essential in the construction here shown that the main invertedU-sha )ed member20. This bafile plate 66 there ore is located inside of the burner cap that has the openings 65. It will be observed that the baflle plate 66 divides the housing 18 into a main burner chamber above the battle plate and into a distributing chamber below the baflle plate 65, the mixing chamber openings 25 communicating with the distributing chamber, therefore the gaseous mixture that is made in the mixing chamber 22 flows to the distributing chamber below the baflle 66 and from this-chamber the gaseous mixture is supplied to all of the burners including the main burner. It flows from this distributing chamber past the edges of the baflle plate to the main burner chamber above it, and it flows from the distributingchamber below the baffle plate into the tubes 17 through which it is conveyed to the auxiliary burners 16, and it flows around the deflected part 85 of the division plate u into the main burner chamber, and the ba e late 66, fitting loosely in the housing, some 0 it flows around the remaining periphery of the baffle plate to the main burner chamber. It will be observed therefore, that the gener ator is adapted to feed the vapor to the mixing chamber, while the mixing chamber feeds the gaseous mixture into the distributing chamber of the housing 18 from which it is distributed to all of the burners including the main burner. The bafile plate is of such size as to leave around its periphery a space 70 for the flow of the hydrocarbon vapor or gas, and also a space 71 around its inner opening 67 whereby suflicient'vapor or gaseous fuel passes upward past the two openings for supplying the necessary combustible mixture for burning at the burner openings 65. At the same time this plate holds within the distributing chamber a sufficient quantity of the gaseous fuel to supply the additional burners 16 so that it flows readilv through the unimpeded openings 72 into the burners 16. It will be understood of course that the amount of vapor or fuel passing to the'burner can be regulated and controlled by this baflle plate 66.

I have found however that by providing the openings and 71 a proper flow of gaseous mixture is supplied to the burner openings 65.

Attention is called to the fact that the opening 69 passes entirely through the said housing and is located above the torch holding member 59 whereby the burner slits 65 and the sub-fire burner openings 86 are lighted by the flame from the initial heating torch 51. The principal function of the opening 69 is to establish a communication from the torch below whereby its flame not only plays on the generator 13 and lights the sub-tire 86, but passes through the open ing 69 and serves in that way to light the valve stems 74 are provided with eyelets 76.

through which an operating rod 77 passes. This operating rod 77 has its. outer 'end fitting into a suitable swivel 78 whereby the rod may be moved back and forth across an adjustable member or rod 79. This rod .79 is provided with a suitable groove 80 into which the rod 79 springs. It will be under stood that this rod 77 has considerable spring between its ends, and the object of that is that the valve can be caused to seat against the end 17 of its pipe and when against the end of the pipe the rod 77 will be in the position shown in solid lines in- Figure 10, and then can be sprung further into the groove 80 thus holding the valve closed under spring tension, while at the same time the valve can be opened more or less and held in its adjusted position by the friction of the rod 77 with the rod 79.

This rod 79 is longitudinally adjustable by providing one end with screw-threaded portions that screw through a downwardly extending portion 81 carrying on its outer end a lock nut 82.- By turning this rod 79, for instance by a screw driver engaging the slot 83, the rod may be turnedto cause more or less'spring tension against the valve when the operatingrod 77 is in the groove 80.

The object of the coil 34 is to cause the flowing oil to travel in the spiral groove formed by the wire in its passage through the generator so that it is thoroughly vaporized when it passes through the outlet nozzle 33. At the same time it is found advantageous in obviating to some extent the formation ofcarbon in the vaporizer, and can be removed should the generator be affected by carbon and washed or cleansed or a new wire put in its place, and at the same time a new'nozzle may be placed on the generator when occasion for it makes it necessary;

w from the distributing chamber into the space between the depending portions 85 of the bafiie plate 66. This hydrocarbon gas flows from the distributing chamber through the chamber below the battle plate 66 and substantial ly against the generator 13 thereby keeping the generator hot for vaporizing the oil fed thereto. By reason of this construction when the burner is once started then a heating flame is maintained through the openings 86 in the U-shaped chamber that substantially-plays against the generator for continuously heating it during the operation of the burner. When the burner is out off by closing the valve 40 then this subsidiary heatingflame is likewise ,cut ofi.

The operation of the device, is as follows The liquid in the tank 2 being under air pressure and the valve 14 opened it flows through the pipe 12 into the generator through the oil inlet 48. The operator then removes the torch 51 from its holder, lights it andpushes it in the holder 50 where a flame will burn due to the perforated member 54 supplying the necessary oxygen. The flame passes through the opening 56 at its top and strikes the generator 13. When the generator has become heated the valve stem 39 is rotated causing the valve 40 to become open-when the oil passes into the generator and is converted into vapor that passes through the nozzle 33. The burner now being in operation the gaseous fuel passes into the distributing chamber, and through the openings 86 supplies-a constant flame within the inverted U-shaped chamber to play on the generator to heat it which continues the vaporization of the oil, for supplying the burners until the va1ve140 is closed.
