45 1n The operation of the apparatus is as follows:

Figure 1 is a central sectional view of a Oombustlble matteras oil, paper, or kindling-is placed in the basin Z2 and ignited, and oil is supplied to the coil either by gravity or under pressure. The oil escapes at the jet or burner e and is ignited by the fire in the basin. In a very short time the coil is sufficiently heated by burning oil to vaporize further supplies of oil, and the vapor escapes and burns at the orifice e. The flame is deflected by the bafl'le j, and a portion escapes around the casting in Z and between the supports of the same and in so doing heats to redness the upper portion of the coil. A smokeless flame also issues from the apertures k in the overlying member or body it, and the latter becomes very hot and refracts heat back upon the coil. By this means the oil is perfectly converted into a highly-combustible gas, and its entire heat may be utilized in the range or heater for cooking or heating purposes.

It will be observed that the process of vaporization is a gradual one-that is to say, the oil is gradually heated up to a very highternperature before being vaporized and when vaporized is instantly discharged and consumed. In other words, owing to the peculiar construction of the apparatus the lower helices of the coil are not as hot as the upper helix, the fact being that when the burner is first started the lower portion of the coil is black. As soon, however, as the apparatus begins to generate vapor the lower portion of the coil takes on a dull red color, while the upper helix becomes a bright red.

It will be apparent that on large ranges and the like a battery of two or more of these oilgas generators and burners may be placed in juxtaposition on the grate-bars'and connected together for simultaneous operation, thereby affording a relatively increased heating capacity.

It will be obvious to those skilled in the artto which the invention relates that modifications may be made in details without departing from the spirit and scope of the same. Hence 1 do not limit myself to the precise construction and arrangement of parts hereinbefore described, and illustrated in the accompanying drawings; but,

Having described the nature and objects of the invention, what is claimed as new, and desired to be secured by Letters Patent, is'

1. The combination of a main burner, a vapor-generator consisting of a helical coil which communicates with the main burner and whereof the helices are exposed to the main-burner flame, and a refractory body overlying and supported independently of the generator and burner and provided with a depending convex portion which projects partly within the axial plane of the coil and constitutes a spreader for the main -burner flame, and with openings at the base of said convex portion for the emission of flames and products of combustion, and with an overhang or flange, which constitutes a baffle for the discharge end of the coil, substantially as described.

2. The combination of a vaporgenerator consisting of an inverted spiral coil provided at its lower end with an oil-inlet and having its other end extending downwardly and transversely of the coil and served centrally thereof with a vapor-discharge outlet, a basin below the coil, and a detachable refractory body overlying the coil and having a depending convex portion which projects partly within the axial plane of the coil to constitute a spreader for the flame, and having openings at the base of said convex portion for the emission of flames and products of combustion.

3. The combination ofa vaporgenerator consisting of an inverted spiral coil provided at one end with an oil-inlet and having its other end terminating in an L-shaped portion which extends below the coil and is provided axially thereof with a vapor-discharge outlet, a basin below the coil, and a detachable refractory body overlying the coil and having legs or supports which rest upon the bottom of the basin, said body having a downwardlydirected convex portion or spreader projecting partly within the axial plane of the coil, and having an overhang or flange, which constitutes a baflie for said L-shaped portion, substantially as described.

4. The combination of a vapor-generator consisting of an inverted spiral coil provided at one end with an oil-inlet and having its other end terminating in an L-shaped portion which extends below the coil and is provided axially thereof with a vapor-discharge outlet, a basin below the coil, adetachable refractory body overlying the coil and having legs or supports which rest upon the bottom of the basin, said body having a downwardly-directed convex portion or spreader projecting partly within the axial plane of the coil, and a depending segmental flange which serves to deflect heat upon said L-shaped or discharge portion of the coil, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing Witnesses.
