ARTHUR D. SUTTON, OF PITTSBURGH, PENNSYLVANIA.

GAS-BURNER.

Specification of Letters Patent.

Patented Nov. 2?, 191% Application filed February 17, 1917. Serial No. 149,314.

To all whom it may concern:

Be itknown that I, ARTHUR D. SUTTON, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention has reference, generally, to heating appliances and the invention relates, more particularly to an improved gas burner.

The dominant object of the invention is to provide 'a gas burner so constructed as to produce a steady and uniform heating flame and to permit the proper admixture of air therewith, in order that all products of combustion will be consumed.

It is also an object of the invention to provide novel air mixing means, whereby, the heating flame, upon the introduction of air' into the burner, will be directly outwardly at substantially right-angles to the burner, thus, aifording the greatest possible heating area for the inflowing air.

Among other aims and objects of the invention may be recited, the provision of a burner of the character mentioned with a view to compactness, and in which the number of parts are few, the construction simple, the cost of production small, and efli ciency and operation high.

The improvements in the details and arrangements of parts will be apparent from an inspection of the accompanying drawings in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention isdi'sclosed for the purpose of imparting a full understanding of the same.

In the drawings:

Figure 1 is a vertical section through my improved burner as applied to an air heating furnace, the furnace being fragmentally shown in section;

- Fig. 2 is a horizontal section of the burner; and Fig. 3 is a side elevation of the same.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring now more specifically to the several figures of the said drawings, it is to be noted that I have shown by way of illustration, my improved burner as applied to an air heating furnace, the housing of the furnace being fragmentally shown and indicated by the numeral 1 and having arranged adjacent one lower extremity thereof a suitable air inlet An air heating and circulating jacket, comprising a double walled structure 3 is arranged within the furnace housing element 1, preferably, in spaced relation from the inner faces of the sidewalls of the same. The outermost wall of the jacketing member 3 is extended downwardly and provided with a laterally extending flange 4, while the remaining wall of the same is arranged in spaced apart relation therefrom and has its adjacent extremity oifset as a 5, the purpose of which will be subsequently apparent.

With more especial reference to the present improvements, the burner may be stated to comprise an annular body structure composed of a plurality of spaced walls designated by the numeral 6, the outer wall thereof is provided with a plurality of gas outlet and burning openings 6. The lower extremity of the outer wall of the burner structure is" provided with a closure ring 7 the outer marginal edge of the said ring being flanged as at 8 and snugly engaged with the adjacent edge of the outer wall. A similar closure ring 9, of less width than the ring 7 is arranged adjacent the lower extremity of the inner wall of the burner structure and is flanged as at 10 whereby the same may be snugly engaged with the lower extremity of the said inner wall. To insure positive connection between the flanged portions 8 and 10 and the said closure rings, suitable cement or other form of securing means may be applied at the point of jointure. To close the space between the remaining extremities of the closure rings 7 and 9, a flanged sleeve 11 is provided and as will be noted, has the several flanges thereof so arranged as to overlap the adjacent end of the said closure rings, whereupon a suitable cement or other fastening means is applied to the same, thus, providing an efficient chamber between the several walls of the burner structure and also maintaining the same in spaced apart relation. To close the upper extremity of the double wall burner structure, the upper ends of the several walls thereof are curved inwardly as at 12 while the outer wall is provided with a slight extension, which extension is crimped to provide means where by the offset portion 5 of the inner wall of the air heating and circulating jacket 3 may wall of the same and to insure proper jointure of the same, whereby, to prevent the escape of gas or other fuel from the chamber of the said burner, a suitable form of cement or other packing is applied over the same.

With a view toward providing means whereby the introduction of air into the burner structure will be permitted, there is formed within the inner wall of the said structure, a plurality of openings, generally indicated by the numeral 13, which openings may be of any suitable size, such as conditions or preference may dictate. In the present embodiment, these openings are shown of a size slightly greater than the gas outlet and burning openings 6, although, it will be understood that should it be desired, the size of the openings may be reduced to accord with the size of the said gas burning openings and the number of the same increased to permit the proper admixture of air with the combustible gas. By so arranging the various air inlet openings 13 within the inner wall of the burner structure, the heating flame passing through the various gas burning openings 6 will be directed outwardly at substantially right-angles to the vertical wall ofv the said burner, thus producing the greatest possible heat ing area for the inflowing air, that is, that air passing upwardly between the housing and circulating jacket 3. Further, it is to be also appreciated, that by so admitting the air,-all of the products of combustion of the gaseous fuel will be consumed.

A gas inlet opening is formed within the closure ring 7 and has arranged adjacent the same an internally screw threaded nipple 14, which in turn, has engaged therewith, a complementally threaded portion of a-gas supply pipe or main 15, the said main extending through a suitable opening formed in one portion of the furnace housing element 1 into engagement with a suitable gas source.

When positioning the burner 6 within the furnace, the lower portion of the same, that is, the outer portion of the closure ring 7 is engaged with the laterally extending flange 4, and as hereinbefore stated, the crimped flange or extension as formed upon the upperextremity of the burner structure is engaged with the offset portion 5 of the inner wall of the air heating and circulating jacket The curved 0- With the burner so positioned in the furnace, gas may be now admitted to the same by way of the main 15 and ignited at the discharge openings 6 by means of a suitable pilot light or the like. By the peculiar arrangement of the gas outlet and burning openings 6, it will be evident, that a steady and uniform heating flame will be produced, which heating flame bythe introduction of air into the burner structure, will be forced outwardly at substantially rightangles to the same, thereby, providing a'plurality of flame jets. 7 To insure the heating of the air as passing upwardly through the air heating and circulating jacket 3, the various burningopenings 6f may be and preferably are formed within the outer wall of: the burner structurein staggered relation. c

From the foregoing, it will be appreciated by workers in theart, that I have provided an exceedingly simple and eflicient gas burner, and one; which by reasonof its mounting within the furnace housing may be readily removed fromthe sameto facilifate repairing .or cleaning f the several parts thereof. 1 V V I claim: 7 j j 1.
