1 Claim.

This invention relates to gas burner attachments that may be associated with natural gas burning equipment in cook stoves, heating stoves,

furnaces, or any other combustion chambers" where itis desirable to create an exceptionally trueblue flame that will not smoke the bottoms of cooking utensils, the inner walls of combustion chambers, or any part of 'the heating equipment wherein such attachment is used.

A further object of the instant invention is to provide a new article of manufacture in the form of a deflectorplatefor gas burners that will act upon the jets of flame adjacent the points are deflected while the remaining portion thereof 1 is allowed to travel in its normalmanner.

It has been proven through extended use of deflectorsembodying this invention that a clean ame free of hydrocarbon particles is produced and that after many hours lof actual heating, utensils will not have thereon a collectionk or deposit of carbon black or soot which normally is the case with natural gas burners not having my deilector forming a part thereof.

It has been found further, that embodiments of this invention will talee the yform of various types of deectors and by way of example, two of said forms are setforth in the accompanying drawing, wherein:

Figure l is a vertical cross section through a gas burnery having. a deector attached in accordance with this invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is an enlarged fragmentary, detailed, sectional view showing the manner of removably attaching one form of the deector.

Fig. 4 is an inverted plan view of the deector per se. l

Fig. 5 is a vertical section through another type of burner andy deiiector illustrative of a modified 'form of the invention.

Fig. 6 is a vertical, cross section through a gas burner, showing a deector, embodying this invention, associated therewith and attached thereto in a manner unlike Athat employed in such forms as shown in Figs. 1 and 2, and,

Fig. '7 is a topy plan view of the attachment shown' in Fig'. 6.

It desirable to form the deflector of sheet metal and to provide integral means of attachment to the burner, and it is this preferred type of deflector that is shown in Figs. l, 2 and 4, however, in most instances burner' II) is of the type illustrated and has a connecting pipe i2 which joins burner IU with the conventional mixing chamber not here shown.

Burner I0 is `provided Awith a aperturesr I4 formed ythrough thev upper wall thereof and a number of theseI apertures I4 are arranged in an annular path around the central opening I6 of this type of lmirner.V All of apertures I4 are disposed toproject jets of name in an upward direction and ywhen the Vnovel deflector is in position, it acts upon the major portion of these jets to deflect the same out oftheir pathof travel while the remaining ones are allowed to continue ina normal manner.

' The deilector proper is formed of sheet metal and made into a truste-conical body' i8 and plurality yoi' f when applied, the edge 20 defining the smallest annular diameter is located adjacent the center of the burner.' As a matter of fact, this edge intersects the axis of all of the apertures I4 in the aforesaid annular Vpath and, in oneform of the device, is held there by a seriesof tongues 22 integral with body I8. Thesetongues 22 are bendable and grip the inner annular face of burner I0 which forms the openingy I6. In'this.

manner deflector I8 may be adjusted toward or from the face of burner I0 which has apertures I4 formed therein.

Another form of attaching means for delector I8 is shown in Figs. 6 and '7. trations, Vthe means comprises a number of pins 24 which are passed into some of the aperturesr I4 and allowed to rest against the annular edge 20 of defiector I8. In this form the lowermost edge is directly against the face of burner I0. While many other forms of the deflector might be employed to produce desirable results, but one other type is here shown. Fig. 5 illustrates the oven-type burner 40 havingv apertures 42 in the lowermost wall, from which is projected the gas at the point of combustion. Deector 44` isy V-shaped in cross section and is associated with In these illustraburner 4U as shown. There is a series of spaced land turned back upon themselves when they strike the angular surfaces of deector 44.

The other and f When employing delectors embodyingthis invention, the mixing chamber which usually governs the amount of air admixed with the natural gas is opened wide to allow as much air to enter as possible. It has been found that in so doing, after axing this novel deflector, a true blue ame is produced which will not create soot or dirt and which is exceptionally hot. The amount of gas burned seems to be reduced for a given length of time and the saving effected, together with the desirable results, has proven to be exceptionally valuable.

Having thus described the invention, what is claimed asv new and desired to be secured by Letters Patent is:

An attachment for gas burners having a series of apertures formed therethrough to permit the escape of gas at the points of combustion and including a series of apertures arranged in an annular path concentric With the axis of the burner, comprising a frusto-conical deflector plate positioned upon the burner to change the direction of travel of most of the jets of flame; and means for removably maintaining said deflector in place, the annular edge dening thesmallest diameter of said deector plate beinglmmediately adjacent to and intersecting the axes of all the MARY E.
