GAS BURNER SHI ELD Filed May 12, 1930 ATTORNEY.

gar el. wmmon Patented July 5, 1932 {UNIT GEORGE L. HAM MON, or sAN raANCrsCO, CALrronNIA, ssIeNon T0 NATIONAL WELD- ING EQUIPMENT COMEANY, INCORPORATED, or sAN rnANorsoo, CALIFORNIA GAS BURNER,- SHIELD Application filed May 12,

My invention relates to gas burner shields and more particularly to shields for a series of gas burners, ortorches all of whose heating flames converge to a single point of in tense heat, for purposes of glass workers, 0 and the like.

To those skilled in this art it has been found that when using natural in this type of burner, some or all of the flames would be blown out when an object to be heated was inserted in the flames. This was caused by the deflected hot air current from some of the flames striking and blowing out the opposing flames from underneath, and the object of this invention is to provide a shield to deflect the hot air current away from the flames and prevent the extinguishing thereof.

Another object is to provide a shield to protect the top and sides of the flames as well as the underside.

Another object is to make a shield that is attached or detached readily.

Other objects of the invention will appear to those skilled in the art to which it appertains as the description progresses.

An embodiment of the invention is shown in the accompanying drawing in which the same reference numeral is applied to the and of which there may be modification.

Figure 1 is a side elevation showing two series of gas burners opposed, and converged so that the flames therefrom come to a meetranged in any suitable way to receive gas from a source of supply.

The numerals 9 to 12 inclusiveindicate the burner tips on the opposed series of burners as and 13 to 16 inclusive show the supply pipes same portion throughout the several views 1930. Serial No. 451,572.

which are supplied with gas in a similar way to the first series described. All the tips are set so that the flames converge at A.

' The burner tips or torches shown in the drawing are of the construction shown and described in my Patent No. 1,835,215, Dec. 8,

18 of which is set very close to the flames and a suitable distance from the end of the tips. Sides 19 and 20 extend upward and have the top member 21 projecting forward from the tips a suitable distance. In this instance the edge 18 and the edge 22 are even.

' The shields on both series of burners are duplicates, and are secured to the supply pipes by means of bolts 23, and a clamp bar 2% in this instance, but may be fixed in position by any suitable means.

In operation the flames maintainv an even andsteady heat at the point A and when an object is inserted at, or adjacent to the point A, some of the flames may be deflected off the object 1I1d 13l16,l10t air blast therefrom strike the shield and be deflected downwardly and around the sides somewhat as shown in dotted lines BB on either one side or the other, depending on how the flame is de-v flected. Without the shield these currents would blow up through the flames in about Ehe way shown by arrow C, and blow out the ame.

In this very simple way total failure has ,I desire to secure by Letters Patent of the United States is as follows, but modifications may be had in carrying out the invention as shown in the drawing and in the above par ticularly described form thereof within the purview of the annexed claims.

I claim: 7

1. A series of opposed gas burner tips, the flames therefrom adapted to converge and meet to form intensified heat therebetween, deflecting shields set at an angle to said flames placed adjacent and below the flames to defleet disturbed hot air currents downwardly and away from the flames when objects are inserted in the meeting point of the flames.

2. A device of the class described comprising opposed gas burners spaced from each other and the flames therefrom converged to meet, in combination with shields set at an angle to the burners for deflecting hot air currents from either of the opposed burner flames away from the opposite flames whereby any disturbance of the flames will cause deflected hot air currents to strike the shield and be deflected downwardly and away from the flames.

3. A device of the class described comprising in combination a plurality of opposed as burners all on the same plane having t 'eir flames meeting, ignition flames in said burners, and means to shield said ignition flames adjacent the tip end of said burners.

4. A device of the class described comprising a series of opposed gas burners on the same plane, each of said burners having a heating flame and igniting means, and means to shield the heating flames adjacent the point ofignition.

5. A device of the class described comprising a series of converging and opposed gas torches having nozzle tips on the same plane,

each of said tips having igniting flames surrounding the heating flame, and shields below the heating flame adjacent the ignition flames to deflect swirling hot air currents from the opposed flame downwardly and away from the heating flame.

6. A device of the class described comprising a shield for each battery of opposed burners having its forward edge close under the heating flames adjacent the tip ends of each. battery of burners, and projecting downwardly and rearwardly' from said edge, side members on said shield, a flat top member lying on said burners and projecting forward above said heating flames adjacent the tip ends of the burners, and means to attach said shield to each battery of said burners.

7. A device of the class described comprising in combination two batteries of gas burners spaced and opposed to each other whereby the flames of each burner converge to a common point of intense heat, a shield for each battery of burners, the edge of said shield extending close to the underside of said flames just forward of the tips of said burners and extending 'rearwardly and the burners of each battery, and projecting downwardly and rearwardly from said edge, and means to attach said shield to each battery of-said burners.
