GAS-BURNER.
Specification of Letters Patent.
Patented Nov. 3, 1914.
Application filed June 13, 1912. Serial No. 703,974.
To all whom. it may concern Be it known that T, A1 B. SHAW, a citizen of the United States, residing at .llVest Medford, in the county ofMiddlesex and State of Massachusetts, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to certain improvements in gas burners particularly in that class of burners of which the \Vellsbach burner is an example, and which carry a refractory tube or mantle to be rendered incandescent by a mixture of air and gas;
The main object of my invention is the production in such a burner of a blue flame" pilot light within the mantle.
Other objects are the production of a perfect blue flame pilot light at the point nearest to the blue flame of the main light; the arrangement of the air inlet in the pilot tube;' the arrangement with the main supplytube of the gas entrance below and independent of the valve controlling the main light; the arrangement of the several parts of the gas burner allowing of the easy and ready assembling of the same; and-the novel construction as hereinafter more fully set forth and claimed, by which a simpler, cheaper, and more :efiective device of this character is'produced than isnow in ordinary use. I
In the accompanying drawings, Figure 1 is a central sectional elevation of a gas burner having my pilot light attachment but showing the mantle in side elevation with the lower front portion broken away.
Fig. 2 is a detail plan view just above the wire netting or grating but with the mantle removed. Fig. 3 is a plan view of the same with the cap and its netting removed. Fig. 4 is a sectional view on the line M of Fig. 1.
Corresponding and like parts are referred to in the following description and indicated in all theviews of the drawings by the same reference characters.
The gassupply pipe is indicated at 5 and to it is attached the tube 6 in the form of a male and female union through which the gas enters the burner, said tube having the usual valve 7 for controlling the supply of gas to the main burner operated by cord 8 to open valve and by cord 9 when it is desired to extinguish the main light by closing air-inlet casing 15,-extending slightly above the recess or transverse slot 19 in the" lower tubular part of the upper portion 20. The upper end of portion 10 is closed with the exception of a needle point opening 29 so that only a small amount of gas passes upward into the upper portion 20 and the slot 19 is of sufficientsize to allow of the passage of a suitable amount of air to form a proper mixture of air and gas Within the tube 20 to give a blue flame pilot light.
' A reducer or perforated cap'12 is at-- tached to the threaded upper male portion of the union or tube 6 and screwed to the upper portion of the cap is the usual pipe 13 having a series of oblong slots and the air passing therethrough being controlled by the turning or adjustment of its outer surrounding slotted pipe 1% provided with the hood or air-inlet casing 15, this casing extending to the top of the pipe 14, which pipe extends about half way up'the pipe 13, A
thus forming an adjustable valve or damper for regulating the admission of air for admixture with the gas to form a Bunsen burner. The mixture of air and gas ascending through the pipe 14 passes into the hood or enlarged chamber 17 of the gallery 16 which latter telescopes over the upper portion of pipe 13 and adapted to slide thereon. The pilot tube 20 is fixedly attached to this gallery passing on an incline through its lower portion into the chamber 17 and then vertically upward along the inner side of the chamber and extending a short distance above the upper edge 21 of chamber 17. The tube 20 changing within the chamber from a round to an oval shape so that the portion extending above the upper edge 21 and for a short distance below 'the edge is oval but is not restricted in tiieair and gas passage.
I have shown in the drawings a cap 22 provided with a grating or netting 23 extending across its top and a disk 24 on the 'under side of the netting secured thereto by the rivet 25, and this cap slides over the outer side of chamber 17 being limited in its downward movement by the under side ofthe netting coming in contact with the top burn within the combustion chamber, giving a blue flame, which in the form shown in the drawings is located immediately above the netting so that the pilot flame becomes a part of themain flame when the main flame is burning.
It is apparent from the foregoing that I have provided a steady constant blue flame pilot light which burning within the combustion chamber becomes, when the main flame is burning, a part of the main flame. The ordinary pilot flame, as now used con tinuously burning outside of the mantle, causes a waste of the gas of the pilot flame when the main flame is burning, wherein in my invention the blue flame pilot light is used when the main flame is burning, becoming a part of the same.
A suitable mantle 26 supported by rod 27 from bracket 28 is placed directly over the cap as is usual in burners of this type. It is apparent that my invention, which is entirely on the pilot portion of the burner together with fiits construction and arrangement in connection with other parts of the gas burner, can be used with a burner having an upright or an inverted mantle, and it is also clear that disk 24 may be left off and the pilot tube extended up centrally of cap or through the netting in cap so that the pilot flame burns within the combustion chamber centrally of main flame. This gas burner can therefore be separated into three distinct and separate parts, each part having several elements or pieces, and that these three parts can be easily and quickly as sembled together; the lower part of the gas burner consisting of the lower pilot tube 10, union or tube 7 with its valve and connecting parts, cap 12, pipes 13 and 14, and air-inlet casing 15; the upper part consisting of cap 22. with its netting, and the bracket 28 with the parts carried by it; and the intermediate part consisting of chamber 17 with its gallery 18 and any parts that may be carried by the same, and the upper pilot tube 20. If desired these several parts may be fixedly connected together, and also if desired the pilot tube may beone continuous piece instead of telescopic as shown in the drawings, but as these changes are apparent and easily understood I have deemed it unnecessary to further illustrate the device other than what I have done.
I claim as my invention In a device of the class described, the combination of a main burner the upper portion of which consists of an enlarged chamber; a telescopic pilot burner tube, one part of which is provided with an air inlet, and extends into said chamber and above the upper end thereof; and a cap fitted over said chamber and having its upper end composed of wire netting which rests upon the end of the pilot burner tube.
In testimony whereof I affix my signature in presence of two witnesses.
