The object of the invention disclosed by the first patent is to provide an oil burner whereby a quantity of crude oil is atomized and then directed in a lineal or axial- direction; and to provide a eentrifugally acting nozzle and means for discharging a-blast- of air at an angle of discharge from the nozzle so as to catch the spray and carry it in a slightly flaring manner to produce a long blast. The second patent. has to do principally with the construction, arrangement, and mounting of the burner and its operating parts. In operation, the oil fed into the bottom of the rotary atomizer or cup is discharged by centrifugal force from the periphery of the cup at right angles to its axis of rotation in an atomized condition. The atomized oil, so discharged, is met by the annular current of air surrounding the cup and deflected from such right angle direction to a greater or less extent, according to the direction and -velocity of the air current.
