GAS-BURNER.

SPECIFICATION'forming part of Letters Patent No. 275,709, dated April 10, 1883.

Application filed November 27, 1882. (No model.)

by declare the following to be a full,clear, and

exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to an improvement in gas-burners; and it consists in certain novel devices and arrangements thereof, whereby a light of a very desirable character is produced.

The specific objects accomplished by the various parts of the burner will be fully deout in the claims.

' Referring to the accompanying drawings, Figure 1 is a central vertical longitudinal section of the burner on line as w of Fig. 2, which is a top view thereof with the globe removed. Fig. 3 is a sectional view through the line 2 z of "Fig. 2, Fig. 4 is a detached view of the burner-tip. Fig. 5 is an end View of a flat burner employing three outlets. Fig. 6 is a side view of same'havinga hood or cone, which isindicated in dotted lines. Fig. 7 is an end view of a burner in which three elongated burners are combined to produce one flame. Fig. 8 is a side view-of the deflector, and Fig. 9 is an end view of same.

A denotes the gas-supply, from which curve upward toward each other the branch pipes a, carrying upon their upper ends the sockets b, in which are secured the lava sections B, having in their upper extremities the metallic tips 0, which tips are provided with the'us'ual outlet for gas. The branches at a will be bent with such relation to each other that the burner-tips, when the gas is ignited, will produce one broad flat flame, By the use of the lava sections B, withthe metallic tips 0, I am able to secure in the same burner all of the advantages of the iron tip,fand at the same time prevent the heat therefrom from passing downward and heating the branches ca. The lava section is a perfect non-conductor of heat, and is a very useful, effectual, and economical in scribed hereinafter, and be specifically pointed strumentality for accomplishing the result desired.

In Fig. 4 I illustrate a detached sectional view of the burner, composed of the metallic tip, lava section, and supplypipe, and the manner of securing these parts together.

Some modifications as to the details of constructin g the metallic tip and lava section, and of securing them together, will suggest themselves to those skilled in the art, and which need not be specifically mentioned.

When employed in the burner the branch pipes a a will be inclosed by the perforated jacket G, upon the upper end of which jacket is the base-plate D, which extends outward from the jacket a proper distance and supports the globe E. The base-plate D is perforated on those portions immediately encircling the ends and side of the central opening through which the burners project,.and beyond this line of perforations the base-plate is cutaway, forming the elongated slots d, arranged adjacent to the periphery of the base-plate and beyond the point of its contact with thejacket 0. That part of the metal which occupied the central slot, 6, through which the burnersproject, as aforesaid, is bent upward to form the flangesf, which encompass said slot and form deflectors at each end thereof, the side flanges forming deflectors and supports for the extensions or flame-Spreaders F. The extensions F are indicated in Figs. 2 and 3, and correspond in size and proportions with each other. They are preferablyzslightly concave, and secured to the flangesf by riveting. There is a space left between the flangesf and the burners, through which a current of air may pass, as hereinafter described.

The globe E is of particular importance, and by its use upon a gas-burner very desirable results may be secured. Its form is illustrated in Figs. 1, 8, and 9. The globe is preferably circular at its base, and its two oppo- 1 site sides converge upward on slight curves towardv the opening G, which extends from one end of the globe to the other, its point of commencement and termination being slightly elevated from the base-plate D. The opening G will be of suflicient width to permit the flame to extend through it. The upper portions of the globe have the appearance of a flattened structure rising from a circular base, and its form and peculiar characteristics will be understood by reference to Figs. '8 and fl.

In Figs. 5, 6, and 7 I illustrate a few modifications of the invention, which consist principally in the arrangement of the tube 122, curving from the gas-supply, and provided with one or more branches, it. Where the tube at is employed in connection with one branch n, the outlets for the gas will be at the points 0 on their two facing sides, and where the tube at is connected with the two branches at a the outlets for the gas will be at the point t on each side of the pipe on and on the inner sides of the tubes '71, whereby when the gas is ignited a single strong flat flame will be produced.

In the modification illustrated in Fig. 5 I provide an independent tube upon the upper end of the gas-supply, which tube passes upward below and on a plane between the pipe mand its branch, and terminates below the upper edge thereof. The employment of the tubes at with one or more branches, at, will produce a broad and efiectual fiat flame, whether used alone or in connection with a hood, T, or with a globe of transparent material and a perforated or slotted base.

hen in use the currents of gas issuing from the burners c 0 will combine, and when ignited will produce a flat flame, the greatest length of which will be at right angles to the vertical plane of and centrally between the branch pipes aa. At the same time the current of air will be induced upward through the perforated jacket 0, perforated base I), and through the space formed between the flanges fand the burners, the effect of which is, in its entirety, to promote a perfect combustion and to draw downward the ends of the flame close to the extensions or flamespreaders F F, so as to increase the size thereof and the brilliancy of the light produced. Below the extensions F F, adjacent to their inner portions, the base D is not perforated. I have found that this construction increases the strength or the current of air to draw the ends of the flame downward toward the extensions F, and to hold it there without alterations in either its size or the brilliancy. The air passing through the perforated jacket 0 encircles the branch-pipes a a and the burners B B, with their metallic tips, on all sides, and, especially, it passes in a current between the said burners at the point of ignition, and at the ends thereof, and over its two opposite sides. The effect of the current of air passing through the perforatedjacket 0 would be the same whether the burners illustrated in Fig. 1 were employed or the modified forms of burners indicated in Figs. 5, 6, and 7 were substituted therefor. In either case the air would pass on all sides and between the pipes of air at the said points to pass upward on the inside of the globe E, promoting combustion and preserving the globe at a moderate temperature. The sides of the globe E being but slightlycurved impels a continuous current of air through the same along its inner sides.

I have found by experiment that when the base-plate D is perforated at the edges of the globe E the result secured is not nearly so desirable as when the elongated slots (1 are formed,and that without the strong current which is promoted by the openings d the air will not pass sufficiently rapid through the globe to produce the result desired. The effect of the slots d will be the same if globes other than the form described above were employed.

By the word lava, as employed in this specification, I mean the stony material known to the trade as lava or steatitc.
