JAKE JOSEPH BARRETT, 01 WHITE PLAINS, NEW YORK, ASSIGNOR TO BARRETT BLUE BLAZE BURNER 00., INC., A CORPORATION OF NEWYOBK OIL BURNER Application filed March 19, 1924. Serial No. 700,338.
This invention relates to improvements in oil burning apparatus.
The primary object to this invention is the provision of an improved oil burner embodying an improved vaporizing arrangement by,
A further and important object of this invention is the provision of a novel design of oil burner embodying novel receptacle and bafiie elements so associated that oil may be most effectively vaporized and led to a place for ignition.
A further object of this invention is the provision of an oil burner showing certain novel features of an oil burner set forth in my co-pending application Serial No. 685,165; filed January 9, 1924.
Other objects and advantages of this invention will be apparent during the course of the following detailed description. 7
In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,
Figure 1 is a fragmentary view of a furnace showing the improved oil burner apparatus as associated therewith.
Figure 2 is a fragmentary cross sectional view taken through the improved oil burner. Figure 3 is a planview of the improved oil burner.
Figure 4.- is a view taken substantially on the line 4-4 of Figure 2, showing the upper part of the burner housing and bafiie.
Figure 5 is a fragmentary cross sectional view of a modified form of oil burner showing certain improved details together with features of the oil burner illustrated in Figure 2.
In the drawings, wherein for the purpose of illustration is shown only a preferred and modified form of this invention, the letter A may generally designate the improved oil burner which is adapted to be used with a furnace B of any approved construction. The oil burner apparatus preferably includes a receptacle C,'upon which and with which an improved member D is associated. Means E are provided for feeding of oil or liquid fuel to the receptacle G, and means F are provided for feeding a blast of air into the oil receptacle C in a novel manner.
Referring to the receptacle construction C of the oil burner the same preferably comprises a pan portion 10 which is of hollow. semi-spherical formation, providing an oil receiving compartment 11 therein. At the annular margin of the pan portion 10 a reduced upwardly extending flange 12 is provided toward the inside surface of the pan portion 10. Centrally of the pan portion 10,
and extending upwardly'within the compartment 11 is a tubular projection 15 pro viding a passageway 16 therein through which air flows from the construction F. Laterally thereof an internally screw threaded opening 18 may be provided which is adapted to receive screw threaded end of a pipe coupling 19; the latter being a detail of the oil feed means E which will be subsequently described. The receptacle or housing C furthermore includes the upper annular portion 20,, which at the lower marginal edge thereof provides a reduced flange 21 adapted to cooperate exteriorly of the flange 12 of the pan portion 10 in providing a lap joint for the pan and its extension 10 and 20 respectively. The extension'or' annular portion 20 extends upwardly from its connection with the pan 10 in vertical manner, and just below the upper marginal edge 22 of the portion 20, and exteriorly of said portion, an annular flange 23 is provided to support the member D in a manner to be subsequently described.
The member D is of novel formation, and may be referred to as a deflector, baffle, or
- the like, and comprises the hemi-spherical positioned just upwardly of the top hollowed body portion 30, which adjacent its upper marginal surface 31 and extending radially outwardly therefrom. provides the substantially L-shaped supporting legs 33, which at their outer ends include depending lugs 34 adapted to seat upon the flange 23 of the oil burner receptacle C in order to support the member D in a depending rela tion within the compartment of the receptacle C. The member D is thus supported in depending relation within the receptacle C directly over the exit end of the air passageway 16, and in a cooperating relation therewith to permit the proper passage of vaporized fuel to the ignition point adjacent the top margin 22 of the receptacle C. Adjacent its upper edge 31 the body 30 is provided with the outwardly and upwardly flaring surface 36 which is arranged in a divergin relation from the convex surface 37 of the dy 30; this flaring surface 36 being marginal edge 22 of the receptacle C and eing provided for the purpose of guiding the fuel vapors outwardly; the fuel vapors igniting adjacent this point and being distributed in the broadest manner throughout the interior of the furnace.
' With respect to the application of the receptacle C and its member D in the furnace B, suitable supporting legs 40 may be provided for supporting the receptacle within the furnace B: the legs 40 having adjustable couplings 41 thereon by means of which the legs may be adjusted to proper lengths for supporting the oil burner so that the ignition circle is at a desired elevation in the furnace.
In connection with the oil burning apparatus A, the oil feed means E includes a supply tank 45, and the oil may be fed from this tank 45 through a line 46 to the coupling 19 above mentioned. In the line 46 is preferably disposed a float controlled device 47 which is adapted to regulate the supply of oil in the receptacle compartment 11, so that the level of the oil in this compartment is always below 'the top margin of the tubular extension 15. A valve 48 may be provided in the line 46 above the float valve for the purpose of shutting off the supply of fuel from the tank 45, or for properly regulating the amount of fuel which flows through the line 46, so that the float valve mechanism need only operate for closing when the burner is inoperatively maintained. A si ht glass 49 may be provided in the line tween the float valve mechanism 47 and the cut-off valve 48, for the purpose of determining the normal amount of fuel which the burner will regularly consume.
The means F for supplying a draft or a blast of air to the passageway 16 of the oil burner preferably comprises a pipe or tube 50 which may extend upwardly into the passageway 16 and which is provided with the trumpet or outwardly flaring portion 51 so that a considerable body of air may be trapped therein for feed through the constricted tube 50 into the air burner receptacle. A damper 53 may be positioned for adjustment in the trumpet portion 51. In connection with the supply of air for the air burner, means may be provided in cooperation with the trumpet 51 and tube 50 for forcing a draft of air through the compartment of the receptacle G; this means consisting of a fan or turbine 55 mounted upon a base 56-, for the purpose of forcing air through a pipe line 57. A tubular extension 58 is provided upon the pipe line 57 which may extend within the compartment of the trumpet 51 into abutting relation with the constricted portion of the trumpet, so that the conduit which leads from the fan 55 to the receptacle C may be enclosed to permit a forceful draft of air to be supplied to the receptacle for directing the fuel vapors to the ignition point.
Careful experimentation has proven certain proportions must be maintained between the housing or receptacle C and the member D. For the best result the exterior surface 37 of the body 30 is convex, and disposed directly above the outlet end of the oil passageway 16 and at a distance from the top edge of the extension 15 which is substantially equivalent to the diameter of the passageway 16. For the furnace such as is ordinarily used in private dwellings, an oil burner may be used in which the radius from which the exterior surface 37 of the member D is struck is equal to 2%, and the internal diameter of the receptacle C and more particularly the portion 20 of this receptacle is 7 The member D for this size of oil burner depends into the compartment of the receptacle C from 2 to 2%.
In operation the liquid fuel is fed from the tank 45 thru the line 46 into the receptacle pan 10 until the level of the fuel lies just below the top edge of the air extension 15; the level of the fuel not being ermitted to rise any higher incidentto the oat valve control 47. A draft or a blast of air is fed through the passageway 16 and striking the surface 37 is deflected laterally of the member D and flows toward the constricted annular outlet between the top of the member D and the top of the receptacle C. This has a tendency to produce a vacuum in the receptacle compartment 11 adjacent the surface of the fuel oil, and the vapors on the fuel oil are carried upwardly toward the top of the receptacle and are ignited at the exit between the top of the member D and the top of the receptacle or housing C; the flames being forced outwardly by the flaring surface 36. The member D, of course, becomes heated and by conduction the lieat is carried into the receptacle and the fuel liquid vaporized.
From the foregoing description of this invention it is apparent that an oil burning apparatus has been provided in which the fuel or oil is treated, vaporized, and burned in a novel manner incident to the novel a1- rangement of parts. The efficiency in combustion is high, and consequently the operating cost is low.
In Figure 5 has been illustrated a modified form of oil burner, in which the pan portion 10 of the housing C is provided with an air passageway 16 which extends laterally through the pan 10*, so that the air tube 50* extends on a horizontal axis into the passageway 16 for feeding of air into the compartment of the receptacle C. This merely illustrates a form of invention to be used in connection with furnaces where the draft arrangement cannot be constructed as is illustrated in the preferred embodiment of this invention.
Various changes in the shape, size, and arrangement of parts may be made to the forms of the invention herein shown and described, without departing from the spirit of this invention or scope of the claims.
