Application filed December 6, 1922. Serial Ito. 605,197.
ToPaZZ whom it may cdncem:
Be it known that L-Lnsmn M. GoLosMrr-H,
a citizen of the United States, residing in" Bhiladelphia, Pennsylvania, lhave invented certain llmprovements in Oil Burners, of which the following is a specification.
One object of my invention is to design a burner so that a minimum amount of steam will be used to break up the oil.
A further object of the invention is to construct the burner so that the oil will be given an initial spiral movement, which will be increased before it is subjected to jets of steam at a high velocity, the-jets being projected against the spirally flowing oil in a direction contrary to the movement of the oil so as to break up the globules of oil thoroughly and produce a mixture in the form of mist, which will readily ignite as it leaves the burner.
A still further object of the invention is to mingle the oil and steam thoroughly in the mixing chamber prior to being discharged from the burner.
Another object of'the invention is to construct an oil burner, in which steam is used to break up the oil, so that .the'pressure of the steam from the nozzle will be dissipated in the burner bybeing projected towards the walls of the mixing chamber so that the mist of oil and steam will leave the'burner under low oil pressure, combustion taking place nearer the end of the burner than in burners where the flow of steam is not retarded.
In the accompanying drawings:
Fig. 1 is a side view of my improved burner with a portion in section to illustrate the spiral path of the oil;

Fig. 10 is an end. view of the se;
Fig. 11 is a perspective view of the tubular section;
Fig. 12 is a perspective view of the steam nozzle; and
Fig. 13 is a perspective view illustrating a modification of the tubular section.
2 is the head of my improved oil burner having a mixing chamber 18. In the walls of the chamber are right and left hand spiral grooves 15. V
'1 is an oil supply pipe having a threaded end adapted to the screw threads at the rear end of the head 2. 3 is a nozzle screwed into the forward end of the head 2 and provided with a projection 4 which is slotted at 5.
The passage 16 in the nozzle is conical and forms a portion of the mixing chamber 18.
Within the head 2 is a tubular section? at 8. In this enlargement, as Well as in the rear portion of the section, are longitudinal slots 8*. These slots are shown as straight slots in Figs. 2 and 11, but they may be spiral,'as at 8 Fig. 13.
lhe enlargement 8 of the tubular section rotate f is held between a shoulder 9 on the head for theoil. This rib 11 has a less pitch than the rib 6, increasing the spiral movement of the oil.
Screwed into the end of the tubular section is a cap 12 having a head 13 closed at the forward end and beveled at the rear, as shown at 17. In this cap is a central passage for steam connected to passages 14 which are inclined rearwardly so that the steam is projected into the path of the flowing oil. The steam, as it strikes the oil, breaks up the oil globules and deflects them into the right and left hand spiral groova 15 in the walls of the mixing chamber 18 of the head 2.
The rear portion of the head 13 of the travels through the contracted passage between the inner walls of the mixing chamber and the cap 12, then into the mixing chamber and through the contracted passage in the nozzle.
' The operation of the burner is as follows: Oil, under pressure, passes through the pipe 1 and is given an initial spiral movement by the rib 10. Then it travels through the slots 8 in the tubular section 7 and then in the spiral channel formed by the ribs 11. While traveling in a spiral path, the oil is subjected to the action of jets of steam, which are projected rearwardly against the flowing oil. The steam enters the burner under pressure through the pipe (Sand tubular section 7 as hereinbefore described. Thesteam breaks up the globules of oil and deflects the oil into the right and left hand spiral grooves 15, causing the oil to be broken up thoroughly without interfering with the forward movement of the oil.
The oil, in its passage through the head 2, is first contracted and then allowed to expand, and is contracted again before leaving the burner in a fine mist and in the best possible condition to be burned.
In a burner constructed according to this invention, the oil is not projected from the burner b the violent action of the steam. The steam tends to retardthe oil, consel guently, the flame is nearer the burner than 1t 1s 1n the types of burner using steam to project the oil.
Furthermore, the walls of the fire chamber, in which the "burner is located, are not burned out bythe action of the flame for the above reasons; and the flame produced is more intense than'the flame produced by burners of this type previously constructed.
The burner can be economically and easily manufactured and can be readily and thoroughly cleaned when necessary.
