OIL-BURNER.

Application filed October 9, 1920. Serial No. 415,828.

To all whom it may concern:

Be it known that I, VVILLIAM Honnenn, a citizen of the United States. residing at Albert Lea in the county of Freeborn and State of Minnesota, have invented certain new and useful Improvements in Oil-Burners; and I do hereby 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.

The present invention relates to oil burners and heaters, and is particularly an improvement over the oil burning heater disclosed in my copending application Serial No. 389,703, filed June 17, 1920.

The object of the invention is the provi sion of novel means for supplying or feeding the fuel at the end of an air inlet passage or pipe, and providingfor the radial flow of fuel and air at the end of such passage or pipe for the mixture and combustion of the fuel and air; I

With the foregoing and other objects in View which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being understood that changes canbe made Within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing,'wherein:--'

Figure 1 is a vertical section of the heater including the improvementsiportions being shown in elevation.

Fig. 2 is a fragmentary sectional view showing a modification.

Fig. 3 is a horizontal section on the line 33 of Fig. 2, portions of the disk being broken away.

The heater shown in Fig. 1 is intended es pecially to be placed within a water tank for heating the water, although it can be used for other suitable purposes. The heater comprises a vertical cylindrical casing 5'of sheet metal or other suitable material having a top or cover 6 provided with an outlet 7 from which the flue or discharge pipe 8 extends, said flue having any suitable damper 9 for controlling the draft. The casing has a concaved lower end or bottom 10.

Air is admitted downwardly centrally within the casing through a vertical air in i let pipe 11 opening through the top 6 of the Specification of Letters Patent.

casing at its upper end to communicate with the atmosphere, and the lower end of the pipe terminates a short distance above the bottom of the casing, thus supplying the air into the casing at the bottom thereof to pass radially in all directions and thence upwardly along the wall of the casing.

.The fuel feed as shown in Fig. 1, com prises'a vertical fuel tube or pipe 12 dieposed'concentrically within the pipe 11, with its lower end terminating slightly below the lower end of the pipe 11, and the pipe 12 ex tends upwardly through a spider 17 and out of the pipe 11, and carries a tank 16 containing the oil or other liquid fuel. pipe 12 has a controlling valve18 above the jc?asi1ng 5, whereby to regulate the supply of ue i In order to facilitate the vaporization of the fuel and mixing thereof with the air at the lower or discharge end of the air inlet pipe or passage 11, a disk or base 13 is secured on the central portion of the bottom 10, and has a central vertical spindle l projecting upwardly in the lower end portion of thepipe 12 in the axis thereof, leaving an annular slot around the spindle within the pipe or tube 12 for the fuel to pass downwardly. The disk 13 is of metal or other similar material, and a disk 15 of the same material is secured to the lower end of the pipe or tube 12, and has a central opening for the downward flow of fuel from the pipe 12. A disk 19 of wire mesh or equivalent material is seated on the lower disk 13 around the spindle 14:, and a disk 20 of asbestos or its equivalent is seated on the wire mesh disk 19 while the disk 15 is seated on the asbestos disk 20. The asbestos disk 20 provides a diffuser through which the oil vapor is delivered, so that the vapor flows radially and is distributed uniformly around the disks. The lower disk 18 has an upturned marginal bead 13 to direct the fuel vapor or gas upward. The fuel thus passes to the edges of the disks 13' and 15, and said disks are of slightly greater diameter than the pipe 11, and there is an annular space between the end of the pipe 11 and disk 15 whereby the air flows radially beyond the edge of the disk 15 to create suction and mix the fuel vapor with the air, and support combustion around and beyond the edges of the disks. The fuel is thus fed gradually to the edges of the disks past The which the air flows whereby to provide the suction at the fuel outlet- The annular flame extends along the bottom 10 and then passes upwardly along the wall of the casing 5, whereby the heat is transmitted through the wall of the casing.

In the modified forms shown in Figs. 2 and 3, the fuel is supplied from underneath the disks instead of from above as shown in Fig. 1. The lower disk 13 does not have the spindle, and the fuel supply pipe or tube 12 has its discharge terminal extending upwardly through the bottom 10 and disks 13', 19 and 20. The upper disk 18 which is spaced slightly below the lower end of the air inlet pipe 11, has a central cap 24 disposed over the upper end of the pipe 12 and provided with a spider 25 therein screwthreaded on the pipe 12, to clamp the disks together and the oil which is delivered from the pipe 12 flows downwardly within the cap 2 on the disk 20 in much the same manner that the fuel is delivered to the disk 20 in Fig. 1.

Having thus described the invention, what is claimed as new is 1. An oil burner comprising a depending air supply pipe, disks disposed across the lower discharge end of said pipe and arranged for the flow of fuel between them to the edges thereof, said disks being spaced from the pipe for theradial flow of air past the edges of the disks, and means for supplying fuel between said disks.

2. An oil burner comprising a depending air supply pipe, a pair of disks disposed across and spaced from the lower end of said pipe for the radial flow of air from said pipe past the edges of the disks, fuel-feeding means between the disks for the flow of fuel to the edges of the disks, and means for supplying fuel between the disks to said means.

3. An oil burner comprising a pair of vertically spaced disks, a wire mesh disk on the lower disk, an absorbent disk on the wire mesh disk, and a fuel supply pipe connected to the upper disk of said pair for supplying fuel on the absorbent disk.

' 4. An oil burner comprising an air supply pipe, a pair of disks disposed across and spaced from the end of said pipe .for the radial flow of air from said pipe past the edges of said disks, anasbestos and a wire mesh disk between the first named disks, and a fuel supply pipe connected to one of said disks for supplying fuel between the first named disks.

5. An oil burner comprising vertically spaced disks, the lower disk having a marginal upturned bead, absorbent means between the disks'for the feeding and flow of fuel to the edges thereof, and means for supplying fuel between the disks to said means.

6. An oil burner comprising a depending air supply pipe, a pair of vertically spaced i disks disposed across and spaced below the lower end of said pipe, the lower disk hav-.

ing an upturned marginal bead, a wire mesh disk on said lower disk, an absorbent disk on said wire mesh disk, and a fuel supply I pipe connected tothe upper disk of said pair to supply fuel on said absorbent disk. -7. An Oll burner comprising. vertically spaced disks, a fuel supply pipe extending upwardly through the lower disk, and the upper disk having a cap disposed over the upper end of said pipe and provided with means engaging said pipe.

In testimony whereof I have signed my name to this specification in the presence of a subscribing witness.
