GAS-BURNER.

SPECIFICATION forming part of. Letters Patent No. 305,535, dated September 23 1884.

Application filed lio vemhel 9, 1883 (Ne model.)

gas-burners,and its object is to produce a flame of great brilliancy and power with a small consumption of gas. I

The distinctive characteristics of the invention and its mode of operation will appear in full hereinafter, reference being' had to the accompanying drawings, in which A Figure l'is a central vertical longitudinal section of a gas-burner embodying the. elements of the invention. Fig. 2 isa top View of the same. Fig. 3 is a view of the roll of wireeloth detached from the flametube. Fig. 4. is a top and side iew of the chimney made in sections, and Fig. 5 is a side and sectional view of a modified form of burner.

In the drawings,A denotes the pipe leading from the source of gas-supply, and upon the end of the pipe is the burner proper, which consists of a suitable frame, hereinafter described, inclosing theherizontal fiametube B,

which is connected with the horizontal tube 0 by the series of smallwertieal tubes D, the tube 0 being in communication with the supply-pipe A. The flame-tube B will be perforated along its upper edge, will be supplied in its interior with a roll of fine wirecloth, F,

or equivalent material, and will, preferably, have screw-caps E at its ends. The wire-cloth or other material will be rolled up and inserted in the tube, the screw-cap on one or both ends being afterward applied. The purpose of the wire-cloth is to retard and superheat the gas, as hereinafter pointed out.

Any number desired of the connecting-tubes D may be employed; or, in lieu of them, I mayv connect the tubes B O by a flat metal tube, as indicated in Fig. 5, this latter being either made a part of the tubes B O or independent thereof, as may be preferred.

The frame of the burner consists of the bowl-. shaped foraminous plate G, surrounding the base of the burnerand supporting the deflector 1-1 and vertical frame I which carries the deflector J, the air retarding and heating plate K, and the flange L, uponwhich the chimney rests. The lower portion of the bowl-shaped part G is cut to receive the tube communieating with the tube 0, and along the upper inner horizontal edge of said part G is secured the deflector H. The vertical frame I extends upward from the outer edges of the horizontal portion of the plate G. It is perforated throughout, and at about its center is secured the upper deflector, .I,which consists of the horizontal. perforated portion Mand the upwardly and inwardly deflected portion N. Around the upper edgeof the vertical frame I is the flange L,for sustaining the chimney, and from one end of the frame I to the other extends the elongated frame. or plate K, the center of which is removed to permit the passageof the flamethroughit, and its outer edges areseparated from the flange L by aspace, S through which air may pass along the inner surfaces of the chimney. or globe. The frame K will preferably be perforated, as indicated, audits office is to retard and partially heat the current of air and turn part of it into the flame, the other and cooler portion of the current being permitted to pass gently upward over the inner surface of the globe or chimney.

The fingers or devices employed for retaining the chimney or globe in place will besuch' as are best adapted to the purpose and to the shape of the chimney. Irecommend the employment of a chimney having fiat sides and flat or oval ends, the whole describing in crosssection an outline substantially in the form of oblong square.

the drawings, and lettered a b c d, respectively, and when thus constructed the retaining fingers 6 will be of proper form and width to cover the joints made by the sections, and will preferably extend to the top of the chimney, b i her nec ed y a n r w s r p of metal to prevent their being sprung outward. There is a great advantage in making the chimney in sections, as describedand it is This chimney may be made 7 in one piece or in four sections, as shown in that one part of the samemay be of colored or s e lass an he o r P Of r f ng a s or that,the chimney may be made wholly of tube 0, whence the heat is communicated to the foraminous bowl-shaped plate G, and in a lesser degree to the vertical frame I, the upper part of the frame being much cooler than the lower part. The flame heats the deflectors H J and frame K. It will be noted that the gas is heated in the tubes B, O, and i 5 D, and is thoroughly diffused before its escape, and that :[he air passing through the heated perforated parts of the frame and circulating about said tubes will also be greatly heated and then deflected into the base or hydrogen part of the flame. That part of the air which is deflected inward by the frame K enters the flame, while the air which enters through the perforated frame I and the perfoations in the deflector J and passes upward through the air-space S is comparatively cool. The frame K, however, breaks up any strong drafts, and heats and turns part of this previously-cool air into the. flame. The parts of the burner and frame are constructed and arranged with a View of so superheating the gas and tempering the air atdifferent points that a broad strong brilliant flame will be producedand give forth a clear pervading light. As an illustration, I will say that with a flametube two and one half-inches in length and containing twenty-seven apertures I have had no difficulty in producing a beautiful flame two and one-half inches in width and four and one-half inches in height from six feet of gas per hour. Of course the flame-tube may be of any length required, the foregoing dimensions having been given mainly with a View of conveying an approximate idea of the ca pacity of the invention.

In Letters Patent granted to myself April 10, 1883, and numbered 275,708, I illustrate an elongated flame-tube connected with the gas-pipe by smaller tubes; but in said patent the elongated flame-tube does not contain a roll of gas retarding and superheating substance, and the light is probably not so desirable as that produced by the present flametube. In the patent to Allen, No. 10,270, datedNovember 29, 1853, is shown an elongated flametube containing a wick inclosed in wiregauze. This patent is for a lamp, and the wick is kept moist by actual contact with the fluid, which is conveyed through a tube to the wick. The wire-gauze causes the oil to spread uniformly through the wick, and prevents it from burning. According to my invention the roll of gas retarding and superheating substance is essentially different from that shown in the patent to Allen and de- '65 scribed therein as a wick inclosed by wiregauze. If this wick and gauze were 'placed in applicants elongated flame-tube, it would not serve to superheat the gas, but the wick would be rapidly destroyed, and the shell of wire-gauze would neither retard the flow of nor superheatthe gas. The roll of wire cloth F used by applicant in the flame-tube must be sufficiently dense to retard the flow of gas, and hence it is called a roll, to distinguish it from a mere tube of wire-cloth. 7 5

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a gas-burner, the elongated horizontal tube B, containing a roll of gas retarding and superheating substance, and connected by means of the series of tubes D and tube Gwith a gassupply, substantially asset forth.
