EDWARD C. KAHN, OF. MILWAUKEE, WISCONSIN.

BURNER.

Application filed January 6,

T 0 (L15 whom it may concern.

Be it known that I, EDWARD G. KAHN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsimhave invented certain new and useful Improvements in Burners; and I do hereby declare that the following .is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in means for generating fuel vapor, more particularly of that type including a generating chamber to which oil is supplied for vaporizing said oil, this chamber being connected with a nozzle through which the oil vapor is discharged for ignition, the chamber being heated by said auxiliary burner which, in devices of this character heretofore contemplated, has been supplied with .oil vapor from the generator.

The vapor supplied by such generator is adapted for heating retorts or furnaces, and in the latter use it is desired to maintain operation of the generator'for comparatively long periods of time without active supervision. It is therefore essential to provide an auxiliary burner for the generator which is steady and reliable in operation.

In generators wherein the supply of fuel for the auxiliary burner is drawn from the generating chamber, a salient disadvantage resides in the fact that such heating supply is affected by pressure conditions in the chamber. Hence, should the main nozzle of the generating chamber become clogged, the gas vapor would back up in saidchamber shutting off the supply of oil thereto and consequently cutting off the heat for the generator, thus halting operation of the entire burner. In view-of the pressure supply of oil for the burner, oil would then fill the generating chamber and be discharged through the nozzle, involving considerable elements of danger and disadvantages in addition to extinguishing the main burner flame.

It is therefore primarily the object of my invention to insure against stoppage of the operation of the generator by utilizing an unfailing source of heat fuel for the gen erator which is afforded by the community service supply of gas.

A further object resides in the provision Specification of Letters Patent.

1919. Serial No. 69,895.

of a simple compact and efiicient structure compassing this object.

\Vith the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts as hereinafter more particularly described and defined by the appended claims.

In the accompanying drawings:

Figure l is a vertical sectional view through an auxiliary burner and generator embodying my invention, the plane of this section being indicated by the line 11 of Fig. 2.'

Fig. 2 is a plan view of the burner, portions of the hood being broken away.

referring now more particularly to the accompanying drawings, 5 designates the wall of a retort or furnace which is to be heated by combustion of vapor supplied by my improved generator and auxiliary burner structure, said wall being apertured to receive a mixing tube 6 for the vaporized oil and having a support 7 disposed there adjacent below the mixing tube and on which is seated the base 8 of my device. A gas burner head 9 is supported by legs 10 upstanding on this base and is connected by a mixing valve ll and cock 12 with a service supply pipe 13 which affords a constant and unfailing source of gas.

The gas burner 9 is provided centrally with a socket 14 in which is threaded a post 15 which carries at its upper end a sleeve 16 receiving the intermediate section 17 of the generator. This intermediate section is connected with outer sections 18 by U-couplings 19, all of said sections being disposed in the same plane and within the heating area of the gas burner 9. A jet nozzle 20 is connected with the end of one of the outer generator sections 18 and arranged to discharge into the'mixing tube 6 whereby to effect a proper admixture of oil vapor and air for discharge into the furnace. The other outer generator section is connected by a downwardly inclined pipe 21 with a needle valve 22 which is supplied with oil by the usual tubing 23, reducing members 24 being disposed between the pipe 21 and the needle valve to compensate for the difference in diameter between the valve port and the interior of the generating chamber. Vhile I have shown a preferred form of generating chamber involving a tortuous path afforded by the various pipe sections and U-couplings, it Will be appreciated that so far as the broader aspect of my invention is concerned, the details of this generator may be varied, the essential feature being the heating of the generator by an entirely independent source of fuel afforded by the community service supply of gas.

. A hood is provided for confining the heat of the gas burner 9 to the generator, said hood, comprising an apertured top and an annular wall 26 carrying inwardly extending bracket arms 27 seating on the U-couplings l9 ofthe generator, said wall being cut away at 28 to receive the end portions of the generator and to limit. movementof the hood. A pilot light tube 29 extends from the gas supply pipe 13 through the wall 5 of the retort or furnace and has anupwardly extended portion terminating at the mouth of the mixing tube 6. Anfexcedingly simple and eflicient structure is thus provided, which may be most readily assembled and which insures a constant and reliable operation.

lVhat is claimed is: r

1. A structure of the class described including an auxiliary burner,a post upstand-' ing from the central portion of'said burner, a sleeve carried by the post, a source'of gas for the auxiliary burner, a generator including .a series of connected pipe sections, the intermediate section being mounted in said sleeve, and means for supplying oilto the generator 2. A structure of the class described ineluding an auxiliary burner, a source of gas generator having its intermediate portion connected with said supporting means and being mounted over the burner to receive the heat therefrom, a burner connected with the generator, meansfor supplying oil to the generator, and a hood surrounding the generator and confining the heat from the auxiliary burner around the former. V

3. Astructure of the class described including an'au'xiliary burner, a source of gas supply for the auxiliary burner, a sleeve supported above the auxiliary burner, a generator carried by said sleeve and mounted over the auxiliary burner to receive the heat therefrom, and means for supplying oil to the generator. 1 r

a. A structure of the class described including an auxiliary burner, a service supply of gas for said burner, a generator arranged to be heated by saidburner, a burner for the generator, means for supplying oil to the generator, a pilot in position to ignite the fuel from the generator, and a gas supply pipe from the service supply of'gas to the pilot whereby to maintain a constant ignition means irrespective of the condition of generation of generator burner fuel.

In testimony that I claim the foregoing I have hereunto. set. my hand at Milwaukee,

inuthe county of Milwaukee and State of Wisconsin.
