OIL BURNER.

Application led February 7, 1925. Serial No. 7,575.

To all whom z't may concern: p

Be it known that I, RAYMOND F. S'rURGIs, a citizen of the United States, and a resident of Rahway, county of Union, State of New Jersey, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

This invention relates to an oil burner for burning low grade oil with freedom from smoke, noise and accumulation of carbon, and is more particularly adapted to be used in household furnaces where it can be placeddirectly on the grate of a furnace built to burn coal or other fuel. The invention comprises a symmetrical burner design in which a circular flame is formed so that all parts of the burner at any zone are under uniform temperature conditions. The burner is made of such a nature that it can be made of rugged parts, is easily taken apart and easily adJus ed for maximum eciency. Y 'Ihe invention will be described withparticular reference to the accompanying 'drawing, in which y j Figure 1 is a vertical section of the burner. Figure2 is a plan view ofa part of the generator. An open frame 1 adapted to be Seton the grate of a furnace or other location has an oil tank portion 2 forming a shallow pan. In theI center of this pan an air intake cylindrical portion 3 forms a pipe for a central air draft, the admission of air to which is under control of a dam r 4, operatable by handle 5. 6 is an outside conical detiector having a damping portion 7 and a handle 8. This element combines the functions of a damper and deflector for the outside draft. Oil is supplied to the tank 2 by means of ing an outer cylinder 12 and inner cylinderv 13, anda series of copper heat conducting gills 14 fastened between theiri as shown in Figure 2. The laminations of this generator oil pipe 9 from a source of oil which may be.

are inheat conductive contact with each other and with the inner and outer walls of the heater so as to give a large surface for the transfer of heat from the metal to the oil. The outer rim 12 of this heater has a handle 15 by means of which the heater may be agitated or rotated back and forth to disturb any possible accumulations of carbon. In order to deflect the central draft down onto the oil, I provide a cap 16 which may have internal ribs 17 screw-threaded Vonto the upper end of the central tube 3. The lower part of the cap is, as shown at 18, formed in a Haring, conical shape in such a manner as to cause the central draft to be first deflected down onto the oil and then escaping over the top` of the oil and meeting, the draft coming up from under the deiiector 6 causes the combined draft, by impinging on the outer surface of the flaring cone 18, to deflect. outwardly to give the desired distribution. The cone 18 will, therefore, become hot and lserve to maintain the combustion at high efficiency. The permeation of the heat from the ame through the burner will result in the generator 14 increasing the evaporation of the oil so as to produce per-l fect combustion. The cap 16 may be adjusted by turning it on the thread on pipe 3 so as to raiseor lower it and thus control the aperture between the cone 18 and the de-v flector 6, which will enable thc operator to nicely adjust the flame to produce the kind of combustion desired.

I claim 1. In an oil burner, the-combination comprising an oil pan, heat transferring gills in the oil pan in heat conducting relation to the oiland the gases o-ver the pan, a central air inlet passing up through the pan, an air de-l Vflector for returning the air passing through mentioned current as it issues from the outer edge of the pan. l v

2. In an oil burner, the combination comprising an oil pan, heat transferring gills in the oil pan in heat conducting relation to the oil and the gases over the pan, said gills being'carried by a combined rotatable carrier and cleaner for removing carbon, a handie on the carrier for manually rotating the same, a central air inlet passing up through the pan, an air delector for returning the air passing through the central opening down to and over the top of the pan, and an outside air delector having conical Walls adapted to direct a current of air against the 10 first-mentioned current as it issues from the outer edge of the pan.
