FUEL-COMBUSTION CHAMBER FOR GAS BURNEBS.
Application filed January 23, 1926. Serial No. 83,186.
This invention relates to a fuel gas com bust-ion chamber member or device particularly adapted for use in connection with the burners of gas cooking stoves of the standard forms employed in gas ranges. The improved device of my invention has for its object and is designed to effect substantial improvement in the combustion of the fuel gas so as to obtain maximum temperatures and better utilization of the heat units generated, thereby to effect economy in the gas.
consumption.
The improved device of my invention may preferably consist of a suitable one-piece casting of a form to be superimposed upon the standard type of gas burners and formed with a marginal upwardly extended flange to be engaged by or in close proximity to the bottom wall of the grid upon which the vessel to be heated rests so that in conjunction therewith it will form a combustion chamber for the improved combustion of the fuel gases. The bottom or lower portion of the burner chamber member is suitably formed with relation to the burner to provide for the admission of air to support combustion with the areas of the openings proportioned to regulate the volume of combustion supporter with relation to the requiretween the finger members of the grid and the base of the vessel: and in operation, the
chamber member, or burner overtop, will become heated to a high degree and'in conse quence have a substantial heating efiect upon the air entering through the limited orifices therethrough, thus contributing an important factor in the more complete combustion of the fuel gas within the confined combustion space wherein a high degree of heat is maintained and combustion efficiency insured.
The described and other features and advantages of my improved device will be more fully understood by reference to the accompanying drawing wherein like referonce characters are applied to the corresponding parts in the several views.
In the drawings Fig. 1 is a plan view of my improved combustion chamber formincr member showing same in position as applied to a gas burner.
Fig. 2 is a vertical cross sect-ion taken on line 2-2 of Fig. 1.
Fig. 3 is a partial plan view, full size,- showing my improved device mounted upon a standard form of burner.
'In the approved embodiment of the features of my present invention as herein disclosed, 1 indicates theimproved-combustion chamber forming member which is'forma tively adapted to be supported in position by being set upon a standard form of gas burner 2 of the radiating" burner arm type having the usual annular walled central opening 3 therethrough, a hollow interior for the distribution of the gas, upwardly.
directed burner orifices 4 and intake pipe extending marginal flange 9 of annular form and a bottom wall composed of inwardly extending segments 'or flanges 10, suitably reducing the space between the burner prongs and connected at their inner ends by the radially disposed and upwardly arched ribs 11 jointed at their inner ends by the small annular wall 12, having a central opening 13 therethrough and which,*as shown, may be desirably inclined or flared toward the upper side thereof. The sides of 'the' segmental bottom portions 10 have their edges formed, as shown, to provide air inlet open-' 'ings 14' between the edge portions'of the segments and the burner arms for the admission of air, to support combustion, at each substantially registering relation to the gas orifices 4. An opening 15 is provided as shown inthe lower portion ofthe marginal flange'and extended into the adjacent segments to accommodate or provide for the usual pilot light or burner as customarily employed with gas ranges. A bridge wall side of the burner arm and in intimate and-Q 16 is provided connecting the segment portions 10 adjacent to the opening 15 to afford structural readjustment thereto. This bridge wall 16 may, as illustrated, be upwardly arched and suit-ably spaced from the marginal flange 9 to allow of its being engaged by a suitable lifter to facilitate removal of the chamber member when desired.
In the operation of my improved device, the combustion of the fuel gas occurs within the combustion chamber formed by the overtop member in conjunction with the vessel to be heated positioned there above. By reason of being so confined within the chamber better combustion of the fuel gases ispromoted as a result of the protection from drafts and cross currents and excessive supply of cold air and as a further result of the heating influence radiated to the combustible elements from the heated metal of the overtop member. The desirable arrangement for admitting the air supply for supporting combustion is further important in contributing to the more perfeet combustion of the fuel gases for, as will be understood, the rising columns of air entering through the openings 14 will be heated to a substantial degree and are further introduced to converge with the gas supply from each side of the burner arms, thereby obtaining a thorough admixture conducive to proper combustion. The air inlets are proportioned to admit the re, quired air supply for obtaining the highest degree of efliciency and the arrangement of the inlets 14 in close proximity to the gas orifices 4, is further advantageous in producing an injector eflect wherein the suction of the gas entering the chamber will operate todraw in an air supply proportionate to the pressure and volume of fuel gas. The inclined annular wall 12, is also of a form to promote intimate mixture of the central air supply with the fuel gas by outwardly deflecting the major portion of the central air column to converge with the gas entering through the centralmost orifices of the burner.
The depth or "height of the enclosing flange portion 9 of the chamber member is proportioned so as to leave a suitable space between the top of the flange and the bottom of the vessel to be heated to provide a suitable outlet for the products of combustion. For this purpose, the top of the flange 9 may be positioned immediately underlying the supporting grid member 7 providing for the escape of the products of combustion between the figure members of the grid as will be readily understood. As a result, the air for supporting combustion is varied with a greater supply admitted at the centermost zone and decreasing outwardly in the direction of movement of the gases as they pass radially to the outlet opening. that it admits a larger proportion of the air to support combustion at the central portion of the combustion chamber or as it may be termed, the inner zone. This is advantageous by reason of the greater Volume of gas admitted at the central portion of the combustion chamber and the air thus admitted is afforded additional opportunity of thoroughly comingling with the gas in that it is obliged to travel a greater distance to the outlet opening. While the specific arrangementillustrated for admitting the air varied as to circular zones diminishing in quantity outwardly is desirable, it will be understood that the specific form of the openings is not essential and may be varied to meet requirements.
WVhile I have shown a suitable embodiment of the features of my invention, it will be understood that various modifications may be made therein without departing from the scope of the invention as defined in the appended claims. It is, therefore, intended that all matter herein shall be interpreted as illustrative and not in a limiting sense.
Having described my invention, I claim:

A combustion chamber member for gas burning apparatus adapted for use with radial arm type burners comprising a marginal side closing wall portion, segmental bottom wall portions arranged to be positioned intermediate of the burner arms, said segmental portions having air intake openings adjacent to the burner arms, said segmental portions being connected at their inner ends to radially disposed connecting ribs and a centrally positioned annular wall connecting the inner ends of said ribs, said wall being upwardly and outwardly flared for deflecting outwardly the central air supply and said chamber member being pro vided with an outlet opening for the products of combustion.
