LOUIS C. IBENNER, 0F TOLEDO, OHIO.

BURNER.

1 0 all whom it may concern:

Be it knownthat I Louis C. BENNER, a citizen of the United btates, residing at T0- ledo, in the county ofLuoas and State of Ohio, have invented certain new and useful Improvements in Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved burner, for use in connection with a stove or heaterof the type disclosed in my prior Patent No. 1288807 issued; December 2 1, 1918, and one object of the invention is to provide a burner which may be formed in two sections releasably connected so that the sections of the burner may be taken apart when it is desired to clean the burner.

Another object of the invention is to so construct the burner that the kerosene or other liquid fuel will enter the burner at the outer end of a nozzle forming aportion of the same and will pass throughpassages upon opposite sides of the nozzle to an outlet valve thus permitting the liquid fuel to be readily converted into a gas before entering the valve housing.

.i-Lnother object ofthe invention is to so construct the burner that the nozzle thereof will be provided with a relatively wide and flat outlet having a battle positioned therein to divide the flame and cause the flame to pass out of the nozzle in a wide and flat flame.

Another objectof the invention is to so construct this burner that the two sections will interlock and thus be braced against longitudinal or transverse movement when the two sections are put together andsecured.

Another object of the invention is to so construct the burner that the same may be Specification of Letters Patent.

This burner is used in connection with a heater of the type disclosed in my previous patent referred to above and including briefly a fuel tank 1 carried by a supporting frame 2 which frame extends above the fuel tank and carriesthe compartment 3 in which the soldering iron or other tools which are to be heated will be placed. A

filling neck 4 is provided for the fuel tank 1 and an air pump15 is provided so that the necessary air compression may be supplied to force the llquid fuel through the outlet pipe 6. The burner which is indicated in general by the numeral 7 in Fig. 1 is positioned as shown in Fig. 1 so thatthe flames will be directed longitudinally through the compartment 3 and this burner is positioned above the pan 8 into which a supply of fuel will be poured when first starting the heater. This burner is of the retort type and it is, of course, obvious that the burner must be heated in order to permit theliquid fuel to be converted into gas. Therefore, when first starting the furnace, the pan will be filled with fuel which will be ignited and this fuel will serve to heat the burner so that when the valve 9 is opened to permit kerosene or other liquid, fuel to flow through the pipe 6 and into the burner through the neck 10, the fuel will be converted into gas.

Thisburner is formed in two sections, the upper section being indicated by the nun'ieral 11 in F 2 and the lower section by the nituneral 12. The lower section is formed in a single casting and is provided with an end wall 13 and sidewalls 14 which extend parallel from the end wall to a point approximately midway the length of the to provide a pocket 17 which communicates with the pocket 15 at one side thereof. Notches 18 are formed in the rear end portions of the side walls adjacent the end wall 13 so that the pan 8 may fit into these notches and thus assist in supporting the burner when put in place as shown in Fig. 1. A nozzle section is cast integral with the side walls and is positioned between the same and provided with a flat and flaring forward or outlet end portion 19' and a trough-shaped rear end portion 20 having notches 21 formed in its upper edge for a purpose to be hereinafter brought out. A post 22 is positioned in the central portion of the flared end portion 19 of this nozzle section and serves to divide the sheet of flame passing throughthe nozzle as will be hereinafter brought out. It should be noted that the nozzle extends beyond the forward ends of the walls as shown in Fig. 3.

The upper section is in the form of a flat plate 23 which rests upon the lower section and has ribs 24 cast integral therewith and extending longitudinally of its under face as shown in Fig. 8. A valve housing 25 is also cast integral with the plate 23 between the ribs 24 and is provided with a rearwardly extending neck 26. This valve housing and the rear end portions of the ribs 24 will fit into the cutout 15 and reduced lower end portion 16 thereof, and a side arm 27 leading from one of the ribs 24 will fit into the cutout 17. Webs 28 are carried by the ribs 24 and provided with flaring forward end portions 29, the webs engaging the upper edges of the nozzle section of the lower burner section and together therewith forming a nozzle having a tubular rear end portion and a flaring outlet end. It should be noted that the plate 23 is thickened between the flaring outer end portions 29 of the webs 28 and that the webs are provided with notches 30 which cooperate with the notches 21 and thus form side openings in the nozzle I gage the flaring end portions 29 of the webs 28 to assist in preventing the two sections from having longltudlnal movement and the =2 side arm 32 which extends from the forward end portion of the upper section is provided with a depending lip 33 for engaging the extended forward end portion of the lowernozzle section as shown in Fig. 4. It will thus beseen that the two sections interlock,

and therefore, when the securing screws 34 are passed through the openings 35 of the side walls 12 and screwed into the threaded openings 36 of the webs 28, the upper and lower sections of the burner will be securely connected and cannot have independent movement and further will be prevented from having any tendency toward warping when they are heated and cool off.

The thickened forward end portion of the upper section is provided with a transversely extendin fuel inlet passage 37 which has its end portion closed by the screws 38 which constitute plugs to prevent the escape of the liquid fuel through the ends of the passage. At one end, the passage 37 communicates with an opening 39 formed in the side arms 32 so that liquid fuel from the pipe (3 may pass through the elbow 10 and up through the passage 39 into the passage 37. Branch passages 40 extend from the passage 37 upon opposite sides of the burner and have their rear ends closed by the screw plugs 41. A side passage 42 is formed adjacent the rear end of the upper section and has its outer end closed by the screw plugs 43. It will thus be seen that the fuel which passes through the passages 40 will pass through the side passages 42 and into the valve housing through the passage 44. This passage 44 is closed at its lower end by the plug 45 and intersects a passage 46 formed longitudinally of the valve housing and having its walls threaded for a portion of its length for engagement by the threads of the valve stem 47. This stem 47 extends through the neck 26 and carries a hand wheel 48 so that the valve stem can be easily rotated. The valve stem is tapered at its forward end to provide a needle valve 49 which extends through the pit 50.

When this burner is in use, the pipe (3 is connected with the elbow 10 which in its turn is connected with the side arms 32 of the upper section. A supply of fuel is placed in the pan 8 and lighted and after the burner has been preheated by the fuel placed in the pan, the valve 47 will be opened and the fuel will flow through the burner. As the fuel enters the burner it passes through the passage 37 and then will pass through the passages 40. In doing so, the fuel will be converted into a gas by the heat, and therefore, when the fuel passes into the valve housing, it will be in a gaseous form instead of in a liquid form. This gas will pass out through the outlet pit 50 and will be ignited. The jet of flame which will be under compression due to the presence of compressed air in the reservoir 1, will pass through the nozzle of the burner and upon reaching the wide and relatively flat outlet end portion of the burner, it will be divided by the post 22 and will pass out of the burner in a flat and relatively wide sheet garages offlame, Therefore, the soldering iron or other tools which are placed in the compartment 3 will be subjected to theaotion of a wide and flat flame which is very: hot and 1 will be quickly heated. There has thusbeen provided a burner which is very efficientin.

operation since theuliquid fuel passesinto the burner across the wide inletend portion of the nozzle and then divides and passes longitudinally of the burner upon opposite sides of the nozzle'before reaching the valve housing. The construction of the burner causes the two sections to be securely but releasably held in engagement with each other and prevents them from being warped. The construction further permits the burner to be easily taken apart and cleaned when necessary.
