GAS BURNER.

Application filed May 11,

T all whom it mag concern:

Be it known that I, FRANK M. TAYLOR, a citizen of the United States, residing at La Fayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in a Gas Burner; 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 thesame.

This invention relates to a gaseous fuel burner.

An important object is to provide a construction enabling a more intense and clearer blue or reducing flame to be produced by the admixture of air with kerosene or other hydro-carbon fuel.

Another important object is to provide a construction in which the quantity of air admixing with the fuel may be adjusted so as to enter in the proper proportions even under varying conditions of draft.

Still another object is to provide such a burner having a generator retaining steel stranded table or other means to assist in breaking up or gasifying the liquid hydro carbon by the admixture with air.

Additional objects are to provide a construction of burner of this type having a cleaning point at the tip to prevent clog ging of the outlet orifice and to regulate the amount of vapor or fuel required for admixture with the air, and further to provide a construction of the generator in detachable parts in order that the steel strandedcable may be removed or replaced.

Other objects and advantages will appear from .a-consideration of the description ,following taken in connection with accompanying drawings illustrating one practical em.- bodiment.

In said drawings Figure 1 is a side elevation of the improved burner;

Figure 2 is a longitudinal sectional view through the burner;

Figure 3 is an inverted plan view of the burner;

Figure 4 is a cross sectional view on the line 4-4 of Figure 1,

Figure 5 is a cross sectional view on the line 55 of Figure 1,

1922. Serial No. 560,132.

Figure 6 is a fragmentary detail eleva-.

tion showing the burner tip, and

Figure 7 is a detail view principally in section taken on the line 77 of Figure 6.

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

In reducing the invention to practice, a metallic casting is provided at 10 which forms a suitable casing for the burner having superimposed at one end a mixing chamber 11 and at its other end ,an arch 12. Casing 10 is provided with a central longitudinal passageway 18, open from end to end. On opposite sides of the passageway, fuel passageways 14 are provided. bound by base walls 15, an arch 16, outer walls 17 and a cover wall 18. The sides of the arch 16 as well as wall 17 are preferably inclined as shown. The mixing chamber 11 may communicate with the passageways 1 1- in any suitable manner as by means, of one or more passages 19 and a flame may be applied. thereto as it flows or issues through slots 20 provided vertically and through the walls 17. Transverse slots or ports 21 are provided in the wall 18.

Extending through the arch 12 and into the chamber 11 is a preheating tube or generator22, being clampedagainst the casing by a set screw 23 mounted in the arch 12. Kerosene or other fuel is supplied through the tube 22 any suitable manner as through a nipple at2 l. Within the tube 22, fine steel stranded cable 22 is disposed so that the fuel will have to pass therethrough which functions to break up the fuel and gasify it.

A tip 25 is screw threaded at 26 into the tube 22 and has an outlet orifice 27 in com: munication with the chamber 11.. A throttle valve is provided .to cooperate with the orifice 27 and consists of a rod 28 which is turnable and slidably mounted ,1 a suit.-

able stufiing box 29 at one ,end of tube 22.

Beyond stuffing box 29, a handle 30 may be provided on the rod 28. Rod 28 at its tip, carries a valve head 31 preferably conical like its seat in orifice 27 detachably secured in place as by a screw threaded shank 82. In the rear of the head 81, the rod 28 is reduced at 38 for communication with one or more slots 34 in the tip 25. This con struction provides shoulders at 35 and 35 I which prevents particles of the fuel entering the orifice 27 and clogging the same. The construction renders the valve self cleaning in addition to enabling it to regulate the supply of fuel and it is one which will not cause enlargement of the orifice 27 through continuous use.

Wall 18 is provided with one or more grooves 18 to contain wick 18 and fuel for ignition to initially heat tube 22 to facilitate the starting of the burner.

The mixing chamber 11 has an opening 3c in its lower wall in communication with the passageway 13 so as to admit air from said passageway into the mixing chamber 11. This opening 36 is provided with a plurality of shutters 37 adapted to collectively close said openings. Said shutters are pivoted to swing on horizontal axes or trunnions at 38 and are adapted to be opened to varying extents so as to supply varying quantities of air from passageway 13 to the mixing chamber. To this end, a control rod for the shutters is provided at 39 being loosely connected thereto at 40 and slidable through guide eyelets 41 suspended from the arch and which rod 39 extends to the rear of the casing 10 and has a manipulating head at 42.

It will be seen that fuel passing through the generating member 22, from a suitable source connected to the nipple 24-, penetrates the fine steel stranded cable, thus becoming divided or broken up or gasified before its passage through the orifice 27. It will be realized that the quantity of fuel admitted is determined by the adjustment of the valve 31, effected through movement of the'rod 28 and handle 3O Air in a commensurate quan tity relative to the fuel emerging from the orifice 27, enters the mixing chamber from passageway 13 through the opening 36 and the quantity admitted varies according to the adjusted position of the shutters 37 under control of rod 39, The proper mix ture of air and gas is thus effected within the chamber 11 and thereafter the same passes to the chambers 14, being ignited as it issues through the openings or slots 20. Due to the provision of the openings or slots 21, the flame or heated air will also issue fromthe openings 21 thus heating the generating tube 22 to assist in gasifying the fuel for preheating it for admixture with the air in the chamber 11.

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

I claim as my invention 1. A burner of the class described having a mixing chamber, means to admit fuel thereto, means to admit air to said chamber in quantities regulated relative to the quan tity of fuel admitted, a substantially straight wall above and parallel with the base of the burner having an inlet opening therethrough, shutter members pivotally mounted in said opening, a slidable rod operable from a distance loosely connected to said shutter members, and guide elements for the rod depending from said wall.

2. A burner having a fuel inlet tube, said tube having a substantially conical outlet orifice, a valve seated in said orifice and ro-- tatable to clean the same, a shoulder on said valve to prevent the passage to said orifice of solid particles carried by the fuel, a tip in said tube in which said valve operates and in which said orifice is provided, said tip being provided with a slot normally in communication with said orifice, and said tip having a shoulder engageable by said shoulder.

3. A burner having a fuel inlet tube, said tube having a tip therein, said tip having a substantially conical outlet orifice, a valve seated in said tip and having a head associated with said orifice and rotatable to clean the same, a shoulder on said valve to prevent the passage to said orifice of solidparticles carried by the fuel, said valvebeing screw threaded to said tip, said valve intermediate its head and screw threads having a recess, said tip having a slot in communication with said recess, said tip having a shoulder engageable by said shoulder.

4. A burner of the class described having a casing, a fuel inlet tube carried thereby, a valve extending longitudinally of and adapted to control the passage of fuel through said tube, a stuffing box in which the valve is journaled, the valve having a manipulating portion beyond the stuffing box, said stufiing box abutting the casing, said tube extending into the stufling box, and said stufling box having a fuel supplynipple in communication with the tube.

In testimony whereof I afix my signature.
