GAS BURNER Filed March 3, 1928 311 newton mww .wg m

` attomcq Patented Feb. 9, 1932 UNITED 4STATES PATENT OFFICE ARTHUR FRIEDMAN, OF CLEVELAND, OHIO, ASSIGNOR TO THE CLEVELAND HEATER COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO GAS BURNER Application filed March 3, 1928. Serial No. 258,871.-

This invention relates to gas burners and in particular to the type of gas burner that is provided with a primary air inlet where a certain amount of air is drawn in and mixed i. with the gas before combustion takes place.

Burners of this type are commonly con-` structed with a burner head having alarge number of ports or orifices, at which the gas is burned.

The purpose and reason'for having a multiplicity of burner ports is to expose a. large area of flame to the air so that the additional oxygen required for complete combustion may be'readily taken from the air, as it is neither desirable nor feasible to premixthe proper quantity of air and gas necessary for complete combustion in burners of this type.

One of the objects of my invention isto provide a gas burner in which the flame of the burner is exposed on all sides to an abundant and changing supply of air.

Another object of my invention is to simplify the construction and reduce the number of parts in a' gas burner of this type.

Another object of my invention is to provide a gas burner having an annular flame which is supplied with air on both sides of the llame.

A further object of my invention is to provide a burner of the type described in which the burner may be readily adjusted to use different kinds of gas and to operate at different gas pressures.

A further obj ect in my invention is to provide a burner of the type described that requires a minimum of machine operations in its manufacture and that can be readily disassembled for cleaning and other purposes.

In general my invention consists of a blueflame atmospheric gas burner having a gas and air mixing tube terminating in an up, standing portion which is adapted to receive an adjustable burner head. The burner head is provided with a central opening and has a deflecting disk or head positioned above said opening to supply and direct a supply of air to the inner surface of the annular flame produced by my burner.

In addition to the great reduction in the number of parts and the resultant simplification of the burner, my improved burner prov1des a novel adjustingmeans whereby air mixing tube 1, adapted to be supplied with gas from the gas cock 2, which carries an adjustable shutter 3, to regulate the flow of air which is drawn into the mixing tube 1, by the inflowing gas from the cock 2.

The inner end of the mixing tube 1, termmates in an up-standing angular flange 4. This flange is provided with an inner conical surface 5 which is adapted to cooperate with a similarly shaped surface 11 forming the outer rim of the adjustable burner head 6.

The annular aperture defined by the surfaces 5 and 11 is adapted to support an annular llame when gas is supplied to the burner. An air spreader cap or dellecting disk 7 is carried on the shoulder 12 of the burner head 6 and is vprovided to direct a supply of air to the inner area of the burner flame.

Adjustment of the burner head 6, is obtained by raising or lowering an externally threaded sleeve 8 upon which the hollow cylindrical extension 13 of the burner head 6 is mounted. A vertical tube 14 integrally formed in the mixing tube 1 provides a guide- Way for the extension 13 of the burner head 6. The tube 14 is internally threaded for reception of the burner adjusting sleeve 8. A lock nut 9 holds the sleeve 8 in the desired position.

Secondary air is supplied to the under side of the spreader cap 7 by way of the sleeve 8, the hollow extension 13 of the burner head 6 and the lateral openings 10 of the spreader cap 7. The arrows a indicate the path of the secon dary air to the inner surface of the -flame. The air spreader cap 7 directs the incoming aforementioned air supply against the inner surface of the flame so that a major portion of this air is available for the purcular imperforate cap pose of assisting in the combustion of the gas. It is apparent that the natural circulation of air around the burner, induced by the heat of its flame, would insure an adequate supply of secondary air to the outer area of the annular flame. The path of this air stream is indicated by the arrows b.

It is possible, by having a ve close adjustment between the conical sur aces 5 and 11 to maintain the very small gas flame which is not apt to flash back and burn in the miXin tube l.

One of t e features of my burner that prevents this iiashing back is found in the relatively long or, deep passage between conical surfaces 5 and'll which is too restricted and long to support combustion and in this manner the flame is prevented from burning back into the interior of the burner. This arrange: ment also eliminates the use of metal gauze in the burner .which is an expensive procedure and a constant source of trouble in the operation of the burner as it becomes clogged with dirt and requires frequent cleaning.

By reason of the various adjustments which may be made on this burner it is adaptable for a great many purposes and it is particularly adaptable for use in connection with gas burning appliances that do not require a very large burner.

Furthermore, it is to be understood that the particular forms of apparatus shown and described, and the particular procedure set forth, are presented for urposes of explanation and illustration an that various modifications of said apparatus and procedure can be made without departing from my invention as defined in the appended claims.

I claim: Y

1. In a as burner, a gas and air mixing tube provid conical face, a burner head having a frusto conical face adapted to cooperate with th`e face of said tube to define an annular burner porti, said burner port providing a restricted outlet passage of substantial length to prevent the flame of the burner from flashing back and burning in the mixing tube, and a cirthe outer edge of which terminates closely adjacent to the margin of said burner port for directing a supply of secondary air from a central passageway formed in said burner parts to the base of the in# ner portion of the burner flame. 2. In a as burner, a gas and air mixing tubev provi ed at its outlet end with a frusto conical face, a burner head. having a frusto,

conical face adapted t0 cooperate with the face of said tube and adjustablv carried thereon to define an annular burner port, said burner port providing a restricted outlet passage of substantial length to prevent the flame of the burner from flashing back and burning in the mixing tube, and a circular imperforate cap' the outer edge of which terminates ed at its outlet end with a frustoclosely adjacentto the margin of said burner port for directing a supply of secondary air from a central passagewa formed in said burner parts to the base of tlie inner portion of the burner iiame.

3. In a gas burner, an horizontally arranged gas and air mixing tube terminating in a vertically arranged cylindrical bowl the upper edge of which is formed with a frusto vconical face of substantial width, a vertically disposed tube carried by the bottom wall of said bowl, a supporting sleeve adjustably carried in said tube, a burner head loosely supported and carried by said sleeve and tube and having a frusto conical face adapted to be located adjacent to the frusto conical face of the upper edge of said bowl whereby to f lll
