BURNER.

Application mam 9, 1927. Serial No. 189,970-

This invent-ion relates to mixing, vaporiz-- ing and ignitingdevices.

This invention has utility in connection with burners, especially {for fuel gases and combustible volatiles.

Referring to the drawings:

Fig. 1 is a fragmentary plan view showing an embodiment of the invention as in a gas range; j l

Fig. 2 isa plan view of-one of the burners of the invention;

F ig. 3 is a bottom plan view of the burner ofFig.2 1

Fig. 4 is a view on the line IV--IV, Fig.

Fig. 5 is a section on the line V-V, Fig. 4; and

Fig. 6 is a section on the line VI-VI, Fig. 2.

Tank 1, say of compressed casing head natural gas, is shown ashaving valve 2 for controlling supply of fuel therefrom as passing by duct 3 to be controlled by valves 4 as to delivery into ducts 5. These ducts 5' are shown as having threadedconnection 6 with passage 7 in burner housing 8 herein shown as of disk form with the passage 7 peripherallyextendingfor an arc extent to then communicate with chamber 9 about central opening 10 of the housing. From this chamber 9 a plurality of jets 11 discharge combustible fuel upwardly for ignition in Additionally, jets 12 are at straight wall portion 13 of the housing. These jets 12 are directed against fuel supply duct 5. The housing 8, adjacent the threaded portion 6, is provided with oppositely extending flanges 14 over which extend return bends 15 of slide 16 having ports 17 shiftable more or less as to register wit-h ports 18 in the housing 8 at the entrance region of thepassage 7. These ports 17, 18,

accordingly provide an adjustable air mixer.

This housing 8 on its under side is provided with pairs of lugs 19 in diametrically disposed regionsas to theopening 10 so that supporting rail 20 from range housing 21 may extend transversely below the burner housing 8 to have bolt 22 through'such'rail or bar 20 carrying washer 23 at the upper side of opening 10 with nut 24 thereon to be thus effective in positioning the burner housing 8 as to the range 21. In some instances it ma 7 be desirable to supplement this mounting of the bar 20, or have a mounting alternatively thereto. To this end plug 25 may be removed from threaded opening 26 and anchoring bar disposed therein. The general grouping of these'bur-ners 8 in a range may, conveniently be such that supply duct-5 for a rearburner, may be sustained by hook 27. of a forward burner. These are features giving stability to the burner grouping as assembled in the range 21.

The supply of fuel from the reservoir or V compression tank 1 is past the valves 2, 4, to the burner housing 8, where it may be ig-. nited say first by holding a flame adjacent the jets 12 and then shifting the flame over to the jets 11. In operation, the impinging of the flame from the jets 12 upon the ducts 5 expands this fuel, and rendersit more readily combustible. This fuel from duct 5 flowing through the passage 7 entrains air from the mixing ports 17, 18. This flow of combustible mixture in the passage 7 has its temperature increased for the heat of combustion of this fuel at the jets 12, warms this housing 8, and thus'brings up the temperature of this fuel beforethe fuel leaves the chamber 9. The fuel has a uniform discharge through the various jets 11, 12, for burner operation in an efficiently maintained uniformity as controlled by the valve 4:.

What is claimed and it is desired to secure by Letters Patent is:

1. burner comprising as an integral structure a disk-shaped housing provided with a plurality of jet openings from upwardly extending cones in a plane, a circular chamber with which said openings communicate, the side of said housing below said openings having diametrically disposed pairs of burner-locating mounting lugs, a peripheral supply passage to'said chamber extending in proximity to a plurality of 3.1K burner comprising a dislcshaped housing provided with a plurality of jet openings approximating a plane, a flat circular chamber below the openings with which said openings communicate, a supply passage to said chamber extending peripherally 1n the plane of the chamber and below the ct oienin s 1n )roxnnitv to a )luraht U U of jet openings for heating action therefrom,

and a coinbustion-supporting air intake to said passage. I

4. A burner con'iprising a disk-shaped housing provided with a flat circular chamber having a plurality of jet openings therefrom in a plane ant a supply passage pestructure a disk-shaped housing provided on an upper side thereof with a plurality of jet openings, a central chamber with which said openings communicate, a peripherally extending supply passage to said chamber provided with a wail in said housing sepa rating said passage from the chamber on one side of the passage throughout the passage extent and a combustion air lateral intake to said passage, and means for adjusting said air intake.

G. A burner housing of general disk form providing a main chamber, a peripherally extending arc supply passage to said chamber provided with a wall in said housing separating said passage from the chamber on one side of the passage throughout the passage extent, and a tangentially extending fuel duct connected to said supply passage, said chamber having a jet opening directed toward said duct adjacent the connection of the ductto said supply passage.

In witness whereof I afiix my signature.

JAMES A. WOOD.
