JACKSON G. GILMORE AND AUGUSTUS J. FRAME, OF COLUMBUS, OHIO.-
OIL BURNER.
Application filed September 1, 1926. Serial 110.1%,057.
This invention relates to improvements in oil burners, and has for one of its outstanding objects the provision of an oil burner so constructed as to efi'ect a thorough commingling of air with the vapors of a liquid hydrocarbon for the purpose of providing eflicient carburation of the fluid to the end of producing a' burner of flicient design, silent and smokeless in operation and economical from a standpoint of fuel consumption.
Another object of the invention resides in the provision of an oil burner formed to include a combustion receptacle provided with relatively deep side walls, a closed bottom and an open top, means being provided for maintaining a limited quantity of oil in'a liquid state in the bottom of the receptacle, the axial portion of the receptacle being provided with an upstanding conduit, terminating-adjacent to the top of the receptacle and provided with spaced upper and lower spray heads through which air under super-atmospheric pressure is forced in substantially horizontal streams across the re ceptacle both immediately above the oil supply in the latter and also at the top of the receptacle where the most active combustion takes place, the arrangement permitting of a thorough commingling of the air with the oil vapors released from the body of liquid oil contained in the bottom of the receptacle, and also to produce high degrees of heat commensurate with the quantity of oil consumed.
A further object of the invention resides in surrounding the receptacle with a casing through which air under substantially atmospheric pressure is led, the relation of the casing to the top of the receptacle being such as to produce an annular opening at the top of the receptacle in substantial reg istration with the upper head of the air conduit so that the combustible vapors will be confined between and commingled with the outwardly and horizontally directed forced air streams discharged from the upper head and with the inwardly and horizontally directed air streams discharged from the annular slots under substantially atmospheric pressure,
With these and other objects in view, as
will appear as the description proceeds, theinvention consists in the novel features of constructlon, combinations of elements and arrangements of parts herelnafter to be fully described and pointed out in the appended claims.
In the accompanying drawing:
Figure 1 is a plan view of the improved 60 oil burner comprising the present invention, Figure 2 is a vertical transverse sectional view taken through the apparatus on the line 2-2 of Figure 1.
Referring more particularly to the drawings the numeral 1 designates the im roved o l burner 1n its entirety. Preferab y, the 011 burner comprises a cast metal combustion receptacle or pot 2 and is formed to 7 provide a bottom 3 and an open top. Ad-
jacent to the upper and annular edge of the receptacle, the latter is formed to include an annular outwardly directed flange 4, provided with a downturned skirt 5, the said flange being received-upon the upper annular edge of an outer sheet metal casing 6, which serves to support the receptacle concentrically within said casing and in' operative relation with respect thereto.
The axial portion of the bottom .3 of the receptacle is provided with an elbow 7, in which is positioned the lower end of an upright air conduit 8, disposed vertically and axially within the receptacle. The conduit is formed to include vertically spaced and horizontally disposed spray heads 9 and 10, which are of appreciably greater diameter than the main conduit and have the outer walls thereof apertured as at 11. An air supply pipe 12 extends horizontally through the casing 6 below the receptacle 2 and has its forward end connected with the elbow '7. the outer end of the pipe 12 being connected with any suitable type of blower (not shown) for the purpose of delivering air under superatmospheric pressure to the axially disposed conduit 8. I
Entering the bottom of the receptacle is an oil supply pipe 13 which delivers a suitable quantity of oil, as indicated at 14, to
the bottom of the receptacle, the level of the'oil being automatically maintained by any suitable regulating means, not herein shown. The bottom of the casing 6 is provided with a lateral extension 15 having the end thereof closed by an apertured shutter 16, which permits air under atmospheric pressure to enter the casing. This air is permitted to pass into the annular chamber 17 formed between the side walls of the receptacle and said casing, the flange 4 being apertured as at 18 to permit the air to ascend and enga c with an annular defleeting ring 19. T is ring is mounted on the flange 4 and is of such curvature as to extend over but in spaced relation from the perimeter of the receptacle 2 in order to provide an annular slot or opening 20 through which the air under atmospheric pressure is led into a mixed state with the combustible vapors and gases generated in the receptacle.
By the provision of the'construction de-- scribed. it will be seen that when the burner is in active operation the air released from the head 10 is intimately combined with the vapors from the oil body 14 in the bottom of the receptacle. These ascending vapors are then commingled with the airstream released from the upper head 9, andthe Vapors or gases are forced upwardly and outwardly in a substantially saucer shaped manner as indicated by the arrows b in Figure 2, where the vapors are also combined with the air stream released by way of the openin 20. This results in the formation of a highly combustible mixture of thoroughly vaporized or atomized form wherein the proper chemical combination between the hydrocarbon and oxygen constituents are present to insure highly efficient combustion and a flat spreading flame covering the grate surface of the furnace.
What is claimed is:
1. An oil burner comprising an open top rece tacle in which oil is maintained ina pre etermined quantity, an air conduit arranged axially within said receptacle and provided with spaced apertured outlet heads, the lower of said heads being arranged above the level of the oil within the receptacle, and the upper of said heads being disposed in registration with the plane of the top of said receptacle, the air passing through said conduit being maintained under superatmospheric pressure theapertures in the air outlet heads being arranged to direct the air horizontally and outwardly into and across the receptacle when discharged from said heads, and'a casing surrounding said receptacle andincluding means at its upper edge for admitting air into commingling relationship with the combustible gases issuing from said 'receptacle. r x
2. An oil burner comprising an open top receptacle in which oil is maintained at a predetermined level, an air conduit arranged axially within said receptacle and formed to include a pair of spaced 'ap'ertured out let heads, the lower of said heads being arranged above the level of the oil within said receptacle and the upper of said heads being disposed substantially in registration with the plane of the top of said receptacle, said heads being of a diameter smaller than the internal diameter of said receptacle and the air being discharged therefrom being under superatmospheric pressure, a perforated fiange near the upper end of said receptacle, a casing surrounding said receptacle and supporting the latter by means of said flange, and a deflecting ring at the upper edge of said casing and spaced from the upper perimeter of said receptacle to provide an annular passage for air under atmospheric pressure to commlngle with vapors generated in said receptacle.
3. An oil burner comprising an open top i receptacle in which oil is maintained in a predetermined quantity, an air inlet provided in the bottom and centrally of said receptacle, a vertical conduit having its lower end removably positioned. in connection with said inlet connection, said conduit including a pair of spaced 'apertured outlet heads of larger diameter than the body of said conduit, the lower of said heads being arranged above the oil within the receptacle and the upper of said heads being disposed horizontally and in a plane slight- ,ly above the top of said receptacle, a perforated flange near the upper end ofsaid receptacle, a casing surrounding said receptacle and spaced from the latter by means of said flange, and means for admitting air into said casing.
In testimony whereof we afiix our signatures.
