Patented Oct. 15, 1929 UNITED STATES PATENT OFFICE ORAZIO J. ANTONELLI, OF FALL RIVER, MASSACHUSETTS, ASSIGNOR T GEYSER INSTAIN'TANEOUS WATER HEATER C0,, 0F FALL RIVER, MASSACHUSETTS, A COR- PORATION OF MASSACHUSETTS GAS BURNER Application filed March 5, 1927. Serial No. 173,045.

This invention relates to an improved gas burner.

It is an object of the invention to provide a gas burner in which a flame ofmaximum intensity will be produced by the use of a minimum quantity of fuel.

It is a further object of the invention to provide such a device in which the flames will collectively concentrate upon an object or an area to be heated.

Another object is that of providing a burner which may be optionally connected to fuel supplies operating under different pressures without the necessity of adjusting the parts of the burner to assure a proper admixture of air and fuel, the burner being so constructed that it will automatically compensate for these differential pressures to produce a fuel mixture having proper components of fuel and air, resulting in a flameof maximum efiiciency.

Still another object is that of furnishing a burner the parts of which will be relatively few in number and individually simple in construction and readily assembled to provide a burner capable of achieving, among others, the objects aforementioned.

An additional object is that of providing I a burner in which the likelihood of combustion occurring within t-heburner body or mixing chamber is reduced to a minimum; in which burner also the the flow of fuel mixture may be reduced to a minimum without any substantial impairment in the efiiciency of operation, and upon which the accumulation of condensation products will be prevented.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

With these and further objects in mind, the invention accordingly comprises an article of manufacture possessing the features, properties and the relation of elements which will be exemplified in the article hereinafter described, and the scope'of the application of which will be indicated in the claim. v

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which Figure 1 is a plan View ofone form of burner embodying the presentinv-ention; and

Fig. 2 is a sectional side view taken along the lines 22 and in the direction of the arrows of Fig. 1.

In these views the burn-er body includes upper and lower portions 5 and 6 spaced from each other and providinga chamber by means of side walls 7. Tubes'8 extend transversely through the burner body and flare upwardly, a suitable series of nozzles 9 being provided in association with the upper portion 5, and each being formed with a centrally-extending passage'10. The foregoing elements, as shown, are preferably all in tegral with each other and may be cast in'a single operation, if so desired.

A. suitable source of fuel supply (not shown) is-connected to a nozzle member 11 extending into a casing 12 provi ing a mixing chamber 13 the upper end 0 this casing being connected with and extending through an opening formed in'the lower portion 6 of the burner body and preferably disposed centrally thereof; it being finally noted that the rear Wall of the casing 12 is formed witha series of openings 14 for the admission of air. In use, gas Will flow under desired Working pressure through nozzle 11 into the mixing chamber 18, and this flow will cause air to be drawn through the openings 14. The fuel mixture will flow upwardly into the body of the burner and strike against the inner face of the upper portion 5 thereof and disperse outwardly toward the nozzles 9 associated with this portion and flow through the bores thereof. It has been found that mixing 1 action additional to the action within the chamber 13 occurs within the burner body, and that with the parts properly proportioned the mixture will be such that it is unnecessary to cover or uncover any of the openings 14 or portions thereof despite fluctuations in the pressure of the source of fuel supply connected with the nozzle 11. Air will flow freely through the bores of the tubes 8, and after the ignition of the fuel mixture emerging from the nozzles 9 the air passing through the burner body willmix with the fuel mixture as it is in process of combustion. In other words, additional air will be'fur nished the gas flames. Satisfactory results are achieved by having the tubes arranged adjacent the series of burner nozzles. The flames of the latter will be drawn inwardly of said burner, the lower member being formed with a central fueladmitting opening, upwardly and inwardly inclined side walls connecting said members and a series of nozzles extending from said upper member and being formed with openings communicating with the space between said members, said nozzles being disposedbeyond the air passages.

to concentrate upon the object or area to be warmed and will not be dissipated in extending beyond the object.

- With aburnerof this nature the smallest amount of gas may flow through the nozzle 11, and the fuel mixture emerging from the nozzles 10 will be so perfectly distributed that'the jets may be lighted individually, 7 even though they may be of minimum height.-

Furthermo're, under all conditions of opera tionnoflare-back into the body of the burner or the mixing chamber will occur, as is the case with standard burners despite the ustment provision associated with the latter.

Also, incident to the fact that, as shown, the upper face of theupper portion 5 is convex and the side walls 7 preferably are inclined outwardly, the accumulation of condensation products (for example, from a heating coil) upon the upper face of the burner is prevented, and, as a consequence, the burner will remain clean and free from rust.

Thus, among others, the objects of this invention have been accomplished, and since certain changes may be made in the above article, and different embodiments of the invention could be made, without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. v

It is also to be understood that the following claim is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope, of the invention which as a matter of language might besaidto falltherebetween.

Having described my invention, what I claim as new anddesire to secure' by Letters Patent is:

A gas burner including a pair of spaced members, each formed w th open ngs, the,

surface ofthe uppermember being" convex and centrally imperforate, upwardly flaring tubes connecting the openings of the lower member with the openings of the upper merito provi-de air passages through the'bod'y
