HYDROCARBON-BL IRNER.

SPECIFICATIONf rming part of Letters Patent No. 757,027, dated April 12, 1904.

Application filed March 28, 1903.

To aZZ whom it may concern:

Be it known that I, THOMAS H. DELANEY, a citizen of the United States, residing at N or' wich, in the county of New London and State of Connecticut, have invented a newand useful Improvement in Hydrocarbon-Burners,of which the following is a specification, reference being had to the accompanying sheet of drawings.

My object is to provide a convenient and economical form of hydrocarbon-burner for use in stoves, ranges, and house-heating apparatus, and particularly to so improve such burners that perfect combustion shall be assured, thus overcoming the objectionable smoke and odor now .so common in this class of burners.

In order to explain my invention clearly, I have provided the annexed drawings, in Which Figure 1 is a side elevation of a burner embodying my improvements, and Fig. 2 is a plan view of the same. My improved burner is built up of three superimposed sections or parts, and in Fig. 3 I have shown the burner with the cover-plate removed. In Fig. 4: I. have shown it with the cover-plate and retortcasting removed, thus disclosing a plan view of the pan: Fig. 5 is a cross-sectional view of the complete burner, taken on line 5 5 of Fig. 2; and Fig. 6. is a similar View taken on line 6 6 of said Fig. 2.

In the drawings the lettera indicates the base-section, which is a pan,"b the intermediate section'or retort-casting, and c the top section or cover-plate which fits over the retort-casting, these sections being preferably of cast metal.

The base-section a is formed substantially as a rectangular pan with upright corner-posts a,upon which the intermediate section b rests, the posts being of such height that a considerable open space is provided between the base and intermediate sections, through which space the flames may pass outward and contact with the adjacent alls of the stove or range when the burner is in use. The bottom of the intermediate section is set in somewhat, as seen in Fig. 1, to receive the described corner-posts 0,. The upper portion of section b is Serial No- 1&9,958. (N0 model.)

formed with a longitudinal channel or recess 6, that is located near one side of said section and serves as a conduit through which a plentiful supply of fresh air is introduced into the burner,as I will explain more fully later. The channel I) is connected with the outside atmosphere by an inlet-pipe 0Z. The intermediate section b is also formed with a central transverse chamber 6 into the lower part of which an oil-supply pipe 6 leads, as seen in Fig. 5, and in the pipe eat some convenient point outside the burner is a valve 6, by means of which.

the flow of oil into the chamber 6 may be controlled. Connected with the central chamber,

6 are oppositely-extending channels F, that connect with like channels 6* at the ends of the said section b, as is best seen in Fig. 3. On the opposite sides of the central chamber I 6 (within the inclosure formed by said chamber and the channels 6 b b) are openings 6 b, and in the center of each of said open 1ngs 1s a vertical pipe-section g, Whose lower ends-are open, as is clearly seen in Figs. 5 and 6. These pipes 9 form mixing-tn bes. A short pipe 9 connects each of said vertical pipes with the described air-conduit b, and the'up.

per end of pipe g is connected bya pipe 9 stricted opening in the form of a plug g having a very small central perforation.

The top section 0 and the intermediate sec? tion Z) are secured together by a number. of

. bolts or screws it.

When my described burner isin service, the

of oil, (preferably crude or refined petroleum.)

pipe 6 is connected with a suitable reservoir When it is desired to start a fire, a piece of.

paper or oil-saturated rag is first placed -underneath the central chamber and lighted. This immediately warms up the bottom and side walls of said chamber Z), so that when a small jet of oil is introduced through the inlet-pipe 6 said oil in seeking to spread over the bottom of chamber 6 is vaporized and in seeking to escape passes through the channels 6 into the end channels 5* and thence escapes through the pipes g -into the vertical pipes g. The rapid accumulation of vaporized oil in the channels I2 6 and 6 creates a considerable pressure, so that said vapor is forced through the small opening g into the vertical pipe where it mingles with a jet of air introduced through the pipe g, thus providing an inflammable gas that burns freely at the lower or discharge ends of the pipes 9. These flames impinge on the bottom of the base-section a and spread in all directions, passing outward through the openings between sections a and b on all sides. The entire structure soon becomes cherry-red and radiates intense heat.

Each of the pipes 9 includes a cut-off valve g and preferably a screw-plug 9 through which the interior of the vertical pipes 9 may be reached and cleaned,if necessary. The cutoff valves provide convenient means for shutting off, either wholly or partly, either of the burners, thus making it possible to shut off at will half of the oil consumption and to correspondingly modify the fire.

It will thus be seen that I provide a burner in which the oily vapor and air are mingled before they are brought into contact with the flame instead of injecting or dropping the oil into a retort where it burnsbefore being suitably mingled with air, as has sometimes been done. My present arrangement, with means for controlling the inflow and mingling of the vapor and air, enables me to proportion and regulate the same so that perfect combustion is attained with theleast possible use of oil.

Having thus described my invention, I claim 1. In a hydrocarbon-burner three superimposed sections, a base-section or pan, cornerposts, an intermediate section or retort-casting resting upon said corner-posts with an airspace therebetween, the bottom of the retortcasting being set in to receive said cornerposts, said retort-casting being formed with a central transverse chamber, oppositely-extending channels connecting with said central chamber and with like channels at the end of said section.
