Henson Wood, .lr Assistant Examiner-Michael Y. Mar Attorney-Sommers & Young ABSTRACT: In a gas burner assembly, a unitary sheet metal base member and a unitary sheet metal cover member, the cover member includes an annular portion having an upstanding, substantially frustoconical portion adapted to house a burner head and a radially extending flat portion, the base member has a closed bottom and a gas duct extending therefrom for supplying gas to the burner head, and the cover member has a flange around its periphery turned down over the periphery of the base member to unite the base member and the cover member.

PATENTEU JUN29 Ian Quantum GAS BURNERS This invention relates to gas burners and particularly but not exclusively to high-pressure gas burners for small portable cooking appliances.

The design of known burners has necessitated a complexity of fittings for connection with the gas supply, particularly in installations where several burners are connected with the same supply and it is accordingly the principal objective of this invention to provide a gas burner of capable economical manufacture and suitable for connection to a gas supply with a minimum of auxiliary components.

With the above-stated principal objective in view there is provided according to the invention a gas burner body fabricated from sheet metal and comprising a base member and a cover member said members in assembly defining a burner housing and a gas duct for connection with a gas supply to direct gas therefrom to a burner assembly supported in the burner housing. Conveniently, the gas duct defined by the assembled base and cover members'may include one or more ports to permit air to mix with the gas stream during its passage therethrough.

Gas burners in accordance with the invention may be thus fabricated from economical stampings with an attendant cost reduction in that at least one connector of the prior art devices is eliminated. Further by suitable design the burner assembly may also comprise several metal stampings with the advantage that the burner and body components may be assembled in one pressing operation.

A practical arrangement of the invention will now be described with reference to the accompanying drawings in which:

FIG. 1 is a general perspective view of the burner from above;

FIG. 2 is a general perspective view from below; and

FIG. 3 is a longitudinal cross-sectional view of the burner shown in FIGS. 1 and 2.

Referring now to the drawings the burner shown comprises a base member 1 and a cover member 2, each pressed from sheet steel of about 16 gauge.

The cover member 2 comprises an annular portion 3 with a dependent skirt 4 on its upper face and a flange portion 5 about its periphery. The skirt tapers from the annulus to a diameter less than the annulus. Extending diametrically from the annular portion 3 is a flat cover portion 6 for a purpose to be subsequently described and including a flange portion 5a continuous with the flange 5 on the annular portion. The base member 2 is of generally circular configuration and of a diameter similar to the annular portion ofthe cover member.

A lateral extension 7 of similar dimensions to the cover portion 6 on the cover member is provided and a channel 8 is formed in this extension extending across the face of the base member to a point in the general vicinity of its center. The base member 1! and cover portion 2 are assembled in juxtaposition and united by turning the peripheral flange portions 5 and 50 on the cover member 1 over the periphery of the base member 2, the cover portion 6 of the cover member being disposed over the lateral extension 7 of the base member to form a gas duct defined by the channel 8. A burner housing 9 is similarly defined by the base member 1 and the skirt 4 dependent upon the upper surface of the cover member 2 and thus if before the base and cover members are united a burner assembly indicated for example only by member 10, is located in this housing the complete burner may then be assembled by a simple flangeturning operation. The extremity of the gas duct 8 defined by the channel and cover portion may be provided with an aperture 131 of any suitable shape to locate or direct a gas jet or the like (not shown) and may include one or more air ports 12 to permit air to mix with gas directed through the duct 8 by the gas jet. ln operation the gas-air mixture flows along the duct 8 to the burner housing 9 and out through the member 10 to atmosphere for combustion. The member 10 is shown for simplicity only as the burner assembly would normally include one or more perforated baffle plates located in position on the base member 1 in the housing 9 below the member l0, and supporting the member 10 in the position it occupies in drawings.

We claim:

1. A gas burner comprising a sheet metal base member and a sheet metal cover member assembled and forming a housing for a burner head having a closed bottom and a gas duct for supplying gas to a burner head supported in said housing; said cover member including an annular portion including an upstanding, substantially frustoconical portion and a radially extending flat portion; said cover member having a flange around its periphery turned over the periphery of said base member so as to unite said base member and said cover member.

2. A gas burner in accordance with claim 1 wherein the upstream extremity of the gas duct includes means for location on a gas jet and said means for location of said gas jet on a gas duct includes a flap on the cover member turned downwardly so as to close the end of said gas duct remote from the burner housing and has an aperture therein for reception of said gas jet.
