HYDROCARBON BURNER.

Application led February To all whom it may concern:

Be it known that I, ADOLPH A. HALTER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon Burners; and I do hereby declare the following to be a full, clean-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 a burner particularly adapted for coal oil or other liquid hydro-carbon fuel which does not readily volatilize.

It is aimed to provide a novel and generally improved construction wherein preheated air will mix with the fuel so that the combustible mixture will reach the burner in a gaseous state.

It is further aimed to provide in such a burner, a novel drop-feed means to discharge or supply the coal oil at the point of admiXture with the air, and with the air supply means arranged to be preheated by the burner.

Still another object is to provide a construction in which the fuel and air supply pipe are compactly arranged in a nove'll manner and with the former supporting the burner.

Various additional objects and advantages will become apparent vfrom a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings z-f 1 Figure l is a side elevation of the burner; Figure 2 is a plan view thereof;

Figure 3 is a central vertical section;

Figure 4 is an enlarged vertical section particularly through the burner and adjacent portions of the fuel and air supply Figure 5 is a rear elevation ;l and Figure 6 is a cross sectional view on the line 6-6 of Figure 1.

Like reference characters designate like or similar parts in the different views.

In carrymg out the invention, a main or feed pipe is provided at 10 having an inlet opening at 11 from which a rod 12, preferably of aluminum, extends forwardly and downwardly and terminates and is free at the front end of said main pipe 10.

A suitable casing 13 is secured at the real` 8, 1923. Serial No. 617,742.

of the main 10 and aA pipe 14 communicates therewith and also with a source of fuel such as coal oil or other liquid hydro-carbon which will not readily vaporize or volatilize.

Adjustably mounted in the casing 13 is a valve stem 15 for which the opening 11 constitutes a seat. Valve 15 is threaded to the casing or a part thereof as at 16 and is adapted to be manipulated through the medium of a knob or handle at 17. Through the adjustment of the valve stem 15, its' position with respect to the valve seat 11 is adjustable so as to increase or diminishv the supplyof oil or fuel to the main 10. The

fuel is admitted to main 10 only in such a quantity that it will How along the rod 12 and drop therefrom at its free end.

A Ycoupling 18 at 19 is screw threaded to the front end of the main 10. Its

zle 14 may be surrounded by a cylindrical 80 removable and replaceable wick 25.

Screw threaded as at 26 into the branch 21 is an air supply pipe 27 which is open -and spaced from the pipe 23 at 28 to facilitate the intake of air. Generally, the pipes 23 and 27 selectively form a loop 'as shown. The rod 12 at its free end is disposed at the entrance to branch 20 and pipe 23.

A burnerA of suitable design is employed as at 29, being cast integral with the pipe 27 or provided in any other way and preferably having an upstanding, cylindrical Vwall 30 through which the pipe 27 passes so that the combustible `mixture emitted from the nozzle 24 will pass upwardly through the 95 cylinder 30 about the portion of pipe 27 within the burner and then discharge through outlet orifices 31 in the top wall of the burner.

In use, the valve stem 15 is yregulated 100 through the medium of knob 17 to enable coal oil or other fuel to enter main 10 by traveling along the rod 12 and then dro ping therefrom into the pipe 23 and nozzl,

24 and then on to the wick 25. Initially, the 10U main 10 may be flooded so that the coal oil may better reach the wick 25. When said wick 25 is saturated, the fuel is ignited so as to warm the air which is drawn in or syphoned at opening 28 and through pipe 110 27 incidental to flow of the fuel from the main 10. After the apparatus has thus been VmV (E 'ma started and .is sufficiently warm, the flame at the yWick is extinguishedV and the air passing through pipe 27 will engage the fuel as it drops from the rod 12, thoroughly miXing With it and gasifying and as a gas passing through the pipe 23 to nozzle 24 and discharging from the latter into the burner 29 and being ignited at the orifices 3l.

As merely one operative embodiment has been illustrated and described, it is understood that changes in the details may be resorted to provided they fall Within the spirit and scope of the invention.

Nhat is claimed is 1. A burner of the class described having a fuel supply pipe and an air supply pipe `.collectively forming a substantially endless gure,said pipes at one end being in communication with each other, means to sup ply fuel tothe fuel supply pipe, the air supply pipe being open at its other end, the fuel supply pipe having a nozzle adjacent the last mentioned end extending towards and terminating short of the air supply pipe, and a burner on the air supply pipe opposite said nozzle.

2. A burner of the class described having a fuel supply pipe, means to feed fuel thereto, an air supply pipe to discharge air adjacent the entrance of said fuel supply pipe to gasify the fuel, a burner on the vair sup ply pipe surrounding a portion ofthe same,

and a discharge nozzle on the fuel supply pipe associated With said burner.V

3. A burner of the class described having a fuel supply pipe, means to feed fuel thereto, an air supply pipe to discharge air adjacent the entrance of said fuel supply pipe to gasify the fuel, a burner on the air supply pipe surrounding a portion of the same, a discharge nozzle on the fuel supply pipe associated with said burner, said nozzle eX- tending toward the air supply pipe, and the free end of said air supply pipe being located adjacent said nozzle.

4.' A burner of the class described having a main pipe, a coupling thereon having branches, a fuel supply pipe leading `from one of said branches, the free `end of said fuel'supply pipe terminating in a nozzle, an air supply pipe extending from the other branch and being open adjacent said nozzle,

and a burner on said air supply pipe adtranceof the fuel supply pipe, the free endy of said fuel suppl-y pipe having an upstanding discharge nozzle, an air supply p ipe open adjacent said nozzle, and a burner partly surrounding said air supply pipe'and disposed thereon in cooperative relation to said nozzle.

6. A burner of the class described having a main, said main having an inlet opening, valve means to control the passage of fluid fuel through said opening, a ccupling at one end of said main provided with branches, a fuel supply pipe leading from one of said branches,` a dropper rod in the main extending from a point adjacent said opening and being free adjacent the entrance of the fuel supply'pipe, the free end of said fuel supply pipe having an upstanding discharge nozzle, an air supply pipe extending from lthe other branch and being open 4adjacentsaid nozzle, a burner partly surounding said air supply pipe and disposed thereon Jin cooperative relation to said nozzle, said burner being integral with said air supply pipe, and astarter Wick surrounding saidY nozzle.
