OIL Bosnian.

Application filed December 13, 1923; Serial No. 680,382.

To all whom it may concern:

Be it known that I, AUBREY A. Aocoon, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Oil Burners; and I do declare the following-to be a full, clear, and exact description. of the invention, such as will enable others skilled vin the art to which it appertains to make and use the same, reference being had to the.ac companying drawings, and to the figures 0 reference marked thereon, which form a part of this specification.

This invention relates to an oil burning system including a feed tank and a burn r for vaporizing hydrocarbon oils, prepara tory to their combustion for the production of heat. The invention contemplates a novel form of hydrocarbon burner including a mixing chamber and an hydraulic pressure feed tank which may be. attached to the service main of a city water system to cause the oil to be put under pressure so. that it will feed to the vaporizing chamber. The generic embodiment of the invention also comprises certain novel details of construction which are included in the preferred em hodiment of the inventionhereinafter specifically described and illustrated in the accompanying drawings, in which:

Fig. 1, is a perspective view of hydrocan bon oil burning system, part of the pressure tank wall being broken away to illustrate the interior thereof. 7

Fig. 2, is a vertical, longitudinal, sectional view through the burner and the mixing chamber, part of the vaporizing chamber being shown in the section.

Referring now tothe drawings by nu morals of reference 1 designates a tank, illustrated as a vertical, cylindrical tank closed at its respective ends. At the lower end of the tank is a valved water inlet pipe 2 and a drain pipe 3. At the top of the tank is a valvedoil inlet pipe 4-. by means of which the hydrocarbon oil can be introduced into the tank from the top. 5 designates an air vent; extending from a point adjacentto the bottom of the tank 1, and projecting through the top is a pipe 6, controlled by a valve 6. The pipe 6. communicates with a pipe 7.. which extends through the top of the tank a short distance as indicated at 8 and is c011 trolled by a valve 9 between the pipe 6 and ,to the coupling 11.

the tank 1. The pipe 7 communicates with a vaporizing tube 10 and is connected to the vaporizing tube by a coupling 11, in which valve 12; The vaporizing tube is in the form of a split tubular ring, the split ends terminating in two tubular legs or extensions 13 and l t, the leg 13 being connected Leg 14': has a depending extension 15, carrying a nozzle 16, adapted to be controlled by the valve'17.

The nozzle is spaced from, but in axial alignmentwith a mixing chamber coniprising a tubular body 1 8,"considerably larger than the nozzle. and into which thenozzle discharges the hydrocarbon oil in the form of vapor gas. The mixing chamber 18 projects through a double wall burner cone having two perforate walls 19 and 20. The perforations 21, atv the basev of the conical wall 20 admit the fuel mixture into the space 22, where the mixture may be .admitted through the perforations 23. It will be observed that the perforations 21 are.

relatively large and are in circular series near the base of the wall 20, wlnlethe perforations 23 extend entirely throughout the wall 19 so that the burning flame will be coextensive with the cone. The cone supports a burner plate or disk 24, having a conical recess 25, into which the apex of the cone is received and near the perimeter of the plate 24: are J-bolts 26, the curved ends of which engage the split ring shaped vapor- The priming tube or burner 29 may be associated with the burner to preliminarily heat the cone. Such burner may be connected to the gas supply pipe and may have an arcuate end 30, following the curve of the burner cone as shown in Figure 1.

Assuming that the parts "are properly assembled and that the oil has been introduced into the tank 1, the valve 81 in pipe 2, may be cracked so that water will flow into the tank, and since the specific gravity of oil is less than that of water, it is obvious that the oil will float on the column of water admitted to the tank.- Since the water in all service pipes is under pressure, it will be ios apparent that the oil will be put under pressure so that if the Valve 9 is; cracked and the valve 12unseated, oil Willflow into the vaporizing tube or chamber 10, and that if this tube has already been heated by a primer such as the burner 29, the oil will be vaporized or gasiiied; then if the valve 17 is open the vaporlzed oil W111 enter themixing .eha mber'l8 to combine with the air toprovide a combustible fuel mixture which is introduced into the conical chamber 32-:Erom which it will pass throughthe openings 21 into the space between the \va-lls l) and 20 of the cone and be emitted through the perforations 23,'W l1018 it may be consumed. Having' in mind that the pressure in the tank 1 \villbe equal in all directions, it is obvious that if the valve6 in pipe 6 is unseated While the valve 9 is crachech Water will be admitted into the pipe 7,' so that Waterand hydrocarbon oil can be fed to the vaporizing chamber, the hydrocarbonoil being converted into oilvapors and the Water into Water tank will be entirely full of Water and have no oil in it. Then the valve 31 may be closechthevalved plpe 8 opened and Water drained from'the tank, a new'charge of oil may then be introduced into the tank through valved pipe 4.
