Specification of Letters Patent.

Patented June 1 1920.

Application filed August 14, 1918. Serial No. 249,776.

To all whom it may concern.-

Be it known that I, FRED M. WALKER, a citizen of the United States, residing Detroit, county of Wayne, State of Michlgan, have invented a certain new and useful Improvement in Hydrocarbon Burners, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being. had to the accompanying drawings, which form a part of this specification,

This invention relates to hydrocarbon burners, and has for its object an improved construction designed to effect a more nearly perfect mingling of vapor and all, to produce a flame of high thermal characteristics, now spoken of as the blue flame, as contrasted with the yellow flame, whlch is much better as an illuminant, but poorer in heat-giving qualities.

In the drawings:

Figure 1 is an elevation of my improved device.

Fig. 2 is a sectional elevation.

Fig. 3 is a plan view along the line aa-rv of Fig. 2.

A represents a pipe rising from a source of compressed air supply (not shown) and terminating in a peripheral cone member B; fitting thereabout with its lower edges engaging the base of the conical part, is a saucer or flaring shell C, provided with a roof or cover portion 1); rising from the tapering conical sides of the part B, with its lower edge slightly spaced upper tube Gr, who'se top portion is encircle by an electric heating coil whose cord terminals J may be connected to a suitable source of power. Within the cone portion B is located a similar but smaller cone R which forms the top portion of a suitable containing vessel for oil and which is connected by means of the channels S with the saucer or shell C, which contains kerosene, to the same level as in the cone B, being fed from a constant level tank through the pipe E. The sides of this cone R being spaced from the adjacent inner surface of the larger cone portion B, the two parts cooperate in forming a contracted passage V, through which an annular body of air is rising, and which acts to draw up the kerosene within the cone R and carry it upward through the pipe G.

Resting on the top of the pipe G is a shell K, the center portion of whose lower surface therefrom, is an I is perforated to afford communication between the pipe Gr and its interior. The center ofthe upper portion of the shell K is formed into a more or less flattened and flaring head L, whose under surfaceand whose peripheral edge are provided with perforations M. Through the top of this head depends a screw stem N, carrying on its lower end an inverted conical member P, which, engaging in the'space where the top of'the pipe G to slightly diminish the net area thereof, and also to divert to each side the rising vaporwhich passes it. Upon reaching the upper end of the pipe G the more or less mingled vapor and air are prevented from proceeding directly to the apertured head piece L and in fact are directed into the space Q toward the peripheral portions of the shell K, after eddying about in which they make their way to the central neck portion which connects with the head piece L, through whose apertures M the vapor is projected, a considerable proportion of this downwardly against the sloping top surface of the shell K, whence it curves upward to mingle with the combustible mixture emerging through the peripheral holes in the head piece L.

Upon starting the device in action, the flow of air upwardly through the pipe A serves joins the shell K, serves to create the suction action upon the kerosene within the small cone R, and the com mingled vapor then rises through the open top F of the conical part B and to the top of the pipe G, where it is heated by the action of the heating coil-H, and proceeds thence past the distributing cone P as already described, being then in condition for ignition. After the burner has been in action for a few minutes, the metal walls have been heated enough to afford sufficient warming influence to the rising air and kerosene vapor, so that the electric coil H may be shut off from further activity. The result is a very efiicient mixture high in thermal qualities, which results in producing the blue flame desired for high heat.

What I claim is: r 1. In a hydrocarbon burner, in combination with an air supply pipe having a tapered upper end, a cone member spacedly located therewithin, means for supplying kerosene to said cone member, an upper pipe member rising above the tapered end of the air supply pipe,

means for initially v heating the top portion of said upper pipe member, a perforated shell piece with whose interior said upper pipe member is connected, and a distributing cone located in the opening between said last named members.

2. A hydrocarbon burner, having in combination with an air and oil mixing pipe, means for initially heating the top portion thereof, an apertured double cone member located Within said oil-mixing pipe, means for maintaining a body of hydrocarbon in position vto be acted upon by suction through said double cone member, a perforated shell member with which the top portion of said air and oil mixing pipe is connected, and a distributing cone located adjacent the point of connection of said air and oil mixing pipe with said perforated shell member.

3. In a hydrocarbon burner, in combination with a mixing tube, means appurtenant thereto for introducing thereinto a flow of air, a source of hydrocarbon supply adapted to be depleted by the suction in said mixing tube, means for initially heating the top of nected with the under a perforated shell piece fixed to the top of said mixing tube, and a conical distributing member located within said shell piece adjacent the top of the mixing tube.

4. A hydrocarbon burner, comprising a perforated shell piece, a mixing tube conside of said shell piece, a conical distributing member located at the point of union of said shell piece and said mixing tube, means for maintaining a supply of hydrocarbon in position to be actedv upon by a condition of suction prevailing within the mixing tube, and a cone member within the mixing tube adapted to cooperate with the walls thereof in amplifying the degree of suction adjacent the supply of hydrocarbon.

In testimony whereof I sign this specification in the presence of two witnesses.

FRED M. WALKER.

said mixing tube,
