HYDROC ARBON-BURNER.

Application filed August 13, 1915.

construction in combination with a particular base having a burner jet surrounded by air admitting jets, said burnerand air jets being inclosed within a frusto-conical combustion member.

Another object of the invention is to terminate the air admitting jets at different elevations with relation to the burner jet.

\Vith the above and further objects in view, the, invention is designed to provide a hydrocarbon burner of substantial construction and symmetrical design adapted to be installed in the various forms of stoves and grates.

Figure 1 in the drawings illustrates the burner in front elevation. Fig. 2 shows a plan view of same. front elevation of the burner showing its component and primary parts in section. Figs. 4 and 5 illustrate a single form of burner. Fig. 6 shows a plan view of one of the burner members with portions removed. Fig. 7 shows an end elevation of one of the burner members with portions removed. Fig. 8 illustrates a sectional view of one of the burner jets.

Referring now more in particular to the drawings, wherein the same parts are des' ignated by the same reference -characters, numeral 1 designates a pair of base members. A connecting web 2 spaces apart and substantially connects the said bases. The bases are provided on their upper surfaces with annular vertical flanges 3 which form heating pans, said pans are filled with a non-combustible and fibrous material 4, such as asbestos, which substance is adapted to absorb the surplus fuel which may accumulate in the heating pan at the time of first lighting same.

A plurality of air jets 5 of varying heights are integrally formed in the base, and are adapted to furnish the necessary oxygen to support combustion at the burn- Specification of Letters Patent.

ers. Said jets are arranged in a cluster Within the heating pans. The air jets are frusto-conical in form and directed toward the center of the pans.

A frusto-conical burner cone (3 is disposed upon each base member and surrounds the heating pan and air jets. Said cone is pivoted to the burner member as illustrated in Fig. 7, and has its upper end provided with a substantially large opening which promotes combustion through which theflame projects.

Over each base member and above the opening of the burner cone is mounted a generating or vaporizing coil 7. Said coil is formed in this instance, and as illustrated, of one coil with the extremities directed in a horizontal and parallel relation above and toward the web, where the pipes are directed downwardly and through the central portion thereof. The extremities 8 of the coils pass through the web 2 and have connection with fuel feed pipe lines 9. Saidsupply lines 9 are arranged in parallel relation and each is provided with a controlling valve 10. Beyond the connection of the controlling valve 10 the supply lines 9 have common connection with a T member 11, which T-member will be connected with a ,fuel reservoir or any suitable means of fuel supply (not.

emit. Spreaders 15 are adj ustably arranged above the burner cone and carried by the lower portion of the coils. Said Spl'tfldt-H'S are adapted to divert the flame and spread it in an even form. The device will be properly installe'd in stoves or grates y arranging said device evenly upon the grate, due allowance being made for air to enter the bottom of the base members.

Figs. 4 and 5 show a modified form of the primary design of the invention in the nature of a single burner, which is provir with projections 17 which are. integraliji' formed upon the burner base. Said proje= tions 17 are adapted to support the coil above the burner cone. The single buru r as illustrated is adapted for use in coal stoves, and in particular where a less heating capacity is required.

Fig. 7 shows the burner cone hinged back and from over the burner base and air jets. In lighting the burners the cone will be lifted as illustrated and the source of ignition applied to the jet, or to the oil, previously introduced into the heating pans and absorbed by the substance contained in the pans. The flow of the fuel through the burner jet and the amount absorbed by the porous substance is readily controlled through valve 10. A pair of openings 18 are provided in one extremity of the device through which the supply lines may be directed where the fuel tank is more conveniently accessible through the side of the-stove in which the device is installed rather than from the front wall thereof.

Among the advantages and features of this hydro-carbon burner, the horizontal arrangement of the coils 7 is an important one. A sufficient lineal capacity of tubing is provided in said coil to admit of high efficiency in generating and vaporizing. The fuel oil will be generated before it has traversed the entire length of the coil, and at this point it will continue through the tubes and pass in contact with the walls of said heated tubes and become highly superheated, which action readily causes a further expansion of the gases forming therein and sets up a substantially high pressure by the time the gases have traversed the coil and passed into the burner jet. Such a feature means that the gases emit through the burner jet under a substantial pressure and that said gases are,

clear and dry and highly efficient in combustion.

The form and proportion of the burner cone is such as to accelerate the passage of air, or create a strong draft through the cluster of air jets, whereby a large volume of air is introduced into the burner and a perfect combustion set up, which results in a flame of high heating efliciency. The varying heights of the air jets is a further important feature in the device, in that the shorter ones project 'air at the base of the flame and support combustion as the gas passes from the burner jet, while the longer air jets direct a volume of air to the upper portion of the flames and there spends the air in the perfect combustion of the unburned gases which may pass upward and through the burner cone.

It is understood that changes and modifications in the form, proportion and minor details of construction may be varied without departing from the principles and combination herein set out and particularly pointed out in the followingclaims, to-Wit:
