IMPROVEMENT lN ATMOSPHERlC-GAS BURNERS.

Specification forming part of Letters Patent No. 220,490, dated October 14, 1879 application filed June 24, 1879.

To all whom it may concern:

Be it known that I, ALBANUS W. MORTON, of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Atmospheric-Gas Burners for Culinary and Heating Purposes, of which the following is a specification.

My invention relates to that class of burners in which an entering current of earbureted hydrogen or coal gas is mixed or commingled before reaching the burning-point with a certain proportion of air; and it consists in certain novel features of construction, which are fully hereinafter set forth.

In the drawings, Figure l is a plan of my improved burner, and Fig. 2 is a side elevationof the same. Fig. 3 is a detail sectional view of a burner-rin g, taken at the gas-inlet.

IT generally construct the burners in a circular form but for some purposes they may be L elongated.

burned.

t R s 1 In the present construction, A A are outer 5 and inner circular burner-rings, (two or more,) it made hollow and provided with jet-perforations at a, for the escape of the gases to be These rings are arranged concentrically, and are supplied with inlet-pipes B B, one arranged to tap the inner and the other the outerring, as shown.

'The tubes or pipes B B are provided with wair inlets b b, and are tapped at 'ftheirrex- 1 tremities by branches O 0 from a gas-pipe, D, {common to both.

E are stop-cocks in the branches, ar- Ffanged to cut off the-currents of gas, and F is L a nipple by which a gas hose or tube may be attached.

Each burner-ring is thus arranged to be used independently of or together with the other, at the will of the operator. If the ring A only is to be employed, the cock E is turned 3 to cut off the gas from the ring A, and vice versa.

When the combined air and gas is admitted to the hollow of the burner-ring, the tendency is to supply the gases more freely to the higher than those at more remote points, and this tendency is most marked in burners hava 5 jets nearest the Inlet, and cause them to burn iug elongated instead of ring tubes. To 0bviate this, and to equalize the jets throughout the rings or jet-tubes, I flare the opening 0 where the tube B opens into the cavity of the .it acts to split the incoming stream and cause the branches of the same to pass into the bore of the burner in opposite directions. The force of the stream of gases is thus slightly checked, the direction of their flow is entirely changed, and their pressure within the burner is equalized,sothatthe jet-flames are rendered of uniform size.

I prefer to provide both burners or burnerrings with this deflector.

As these burners are usually constructed, the heat-rays that are directed downward are absorbed by n0n-reflecting surfaces below the burner. I utilize these rays, in the main, by employing a horizontal reflector, H, arranged below the burner, and interposed between it and any dark non-reflective surface upon which the burner or stove may set.

Although not shown in the drawings, Imay employ a shell or casing for the burner, and provide it with suitable bars to suppert the article to be cooked or heated. This shell may conform to the shape of the burner in plan, and the reflector H may form a bottom therefor, being-perforated, as at g g, to permit the passage of air.

The burner may be provided with legs or supports, and the reflector may be attached to it by a central screw, h, as shown.

I am aware that concentric ring-jet burners having their annular cavities arranged to terminate in a pendent cone, the apex of which is tapped by the gas-inlet pipe, have been employed, and I make no claim to this. Such a construction is not well adapted, however, for flat horizontally-arranged burners like mine, as somuch space is required to form the cone below. Such a construction is also quite costly.
