HYDROCARBON-BURNER.'

SPECIFICATION forming part of Letters Patent No. 620,678, dated March 7, 1899.

Application filed January 14,1898. Serial No. 666,605. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE H. SHERMAN and PETER J. SHERMAN, citizens of the United States, residing at Detroit, in the county of WVayne, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Burners; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in hydrocarbon burnersg and it consists in the construction and arrange= ment of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide a burner of this class with a vaporizing-chamher so located within the center of the burner as to be acted upon by the heat therefrom, so that the hydrocarbon fuel which is fed into said vaporizing-chamber will, by means of the intense heat in said chamber, become thoroughly vaporized, which vapor passing from said chamber is evenly distributed over the bottom of the burner and supplied in due proportion to the several combustion-chambers or flame-spaces thereof. This object is attained by the construction and arrangement of parts illustrated in the accompanying drawings, in which Figure 1 is a plan view of our improved burner. Fig. 2 is a transverse section therethrough, as on line 2 2 of Fig. 1.

Referring to the letters of reference, A designates the burner, which is herein shown in circular form and comprises aseri'es of angular sections B, arranged in a circle, so that their opposed inclined sides Ct stand approximately parallel, forming combustion-chamhers or flame-spaces C between'their adjacent walls. The walls of the sides a of the sections of the burner are provided with a series of vertical slots 0 to afford passages through which air may pass into said flamespaces, which air mingles with the rising vapor and supports combustion in a manner well understood. The slotted walls of the burner-sections are supported by a web B,

which extends horizontally between said walls and crosses the interior of the burner-sections, serving to prevent the Walls of said sections from warping.

The arrangement of the sections B of the burner is such that an annular space or chamber D is formed between the inner ends of said sections which inclose said annular spacea Within said central annular space and embraced by the inner ends of said sections of the burner is a vaporizer D, consisting of a hollow pear-shaped casting having a com municating opening I) at the top in which the inner end of the fuel-supply pipe E is secured, which pipe is provided with a slight declination to facilitate the flow of fuel therethrough. The side walls of the vaporizer D converge inwardly and terminate in a reduced bottom d, through which is a central aperture 6.

The bottom of the burner consists of a circular plate F, having a raised marginal flange f, which embraces the burner-sections,

and having a circular depression or channel g. This channel extends under the burnersections B and serves to convey the vapor to the flame-spaces between all of said sections. It will be observed that the sections B of the burner rest directly upon the outer margin of the bottom F of said burner, as at h, while the central portion of the surface of said bottom within the circle described by the channel g is depressed, so as to stand below the bottom of said sections of the burner, forming a free communicating space between them within the circle of said channel, as at i, by which arrangement the fuel or vapor passing from said vaporizer onto said bottom is equally distributed in all directions from the center of said bottom of the burner outward to the channel g.

In the operation of this burner a small quantity of fuel being permitted to flow through the supply-pipe E, said fuel will discharge from said pipe into the upper end of the vaporizer D and trickle down the sides of said vaporizer, and in so doing will spread out and expose an increased area of surface to the action of the air, thereby facilitating vaporization. The vapor so formed and that portion of the fuel which remains unvaporized will pass from the vaporizer through the aperture e in the bottom thereof and fallupon the bottom F of the burner, over the surface of which it spreads and flows into the channel g, from which the rarefied vapor rises in the flame-spaces C of the burner and is burned therein, the air to supply combustion in said flame-spaces passing through the slits c in the sides of the burner-sections, so that the flame burns from all of the radial flamespaces 0 of the burner, producing an intense heat. The heat of the flame within the flamespaces of the burner which surrounds the vaporizer D is communicated to said vaporizer, so that said vaporizer becomes intensely heated, as it is, because of its position in the center of the burner, subject to the heat of the flame-spaces upon all sides thereof. This intense heat which is imparted to the vaporizershortly after starting the burner results in a more perfect vaporization of the hydrocarbon fuel as it passes therethrough, so that all of said fuel is not only vaporized, but said vapor is highly expanded, enabling a more perfect mixing of oxygen therewith when it enters the flame-spaces of the burner, and thereby attaining the highest degree of combustion.

G design ates a central cap which closes the upper end of the central chamber D within the burner and confines and retains the heat of said central chamber around the vaporizer located within said chamber below said cap. Said cap is provided with a depending flange H, to which the burner-sections are connected by means of projecting lugs 7r. on said burnersections, which enter apertures m in said flange. I

In most hydrocarbon-burners where a vaporizer is employed, said vaporizer is usually located below the burner and consequently below the point of the generation of heat, so that the vaporizer becomes but insufliciently heated at best, owingv to the tendency of heat to rise. In our arrangement the vaporizer is located within the center of the burner and is surrounded by the heat and flame produced by the combustion of the fuel,so that said vaporizer is subjected to an intense heat, whereby the hydrocarbon fuel passing therethrough is quickly and perfectly vaporized, resulting in a more perfect combustion of said fuel and obviating any smoke or disagreeable odor.

Having thus fully set forth our invention, what we claim as new, and desire to secure by Letters Patent, is;.

1. In a hydrocarbon-burner, the combination of the burner provided with a central space or chamber and having radial flamespaces leading from said chamber, the vaporizer located within said central chamber'of the burner at the inner point of termination of the flame-spaces thereof, said vaporizer having apertures for the entrance and discharge of the hydrocarbon fuel, the solid bottom below and removed from said flame-spaces and adjacent the lower end of said central.

chamber.

2. In a hydrocarboiyburner, the combination of a series of burner-sections arranged in circular form having radial combustionspaces between them, a central chamber located at the inner terminus of said radial spaces, a vaporizer located in said chamber consisting of a hollow body having an inductopening at the top and a discharge-opening at the bottom and located above the plane of the bottom of the burner, the burner-bottom located below and removed from said com-. bustion-spaces.

3. In a hydrocarbon-burner, the combination with the burner having a central chamber therein, radial flame-spaces leading from said chamber, a vaporizer located within said central chamber, said vaporizer consisting of a hollow pear-shaped body, the fuel-supply pipe communicating with the top of said vaporizer, the bottom of said vaporizer being contracted and provided with a single central aperture, and the burner-bottom located below said vaporizer and removed from the lower ends of said flame-spaces.

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