WILLIAM MELAS, OF RIDLEY PARK, PENNSYLVANIA, ASSIGNOR 0F ONE-HALF '10 DAVID TOWNSEND, 0F PHILADELPHIA, PENNSYLVANIA.
. nermmzme err-B RNER To all whom it may concern Be it known that I,.WILLIAM MELAS, a citizen of the United States, residing at Ridley Park, in' the county of Delaware and State" of Pennsylvania, have invented certain new and useful Improvements in EqualizingOil-Burners, of which the fol burners has not a steady pressure, but one which varies between a certain maximum and minimum ,which variations are constantly re-occurring inacertain time-interval; moreover, the magnitude of said pulsations, or the difference between maximum and minimum pressure is not constant, but varies in the measure as 'the compressor is taxed. This unsteadiness of pressure causes an unsteady working of the burners supplied with air which is mostundesirable and isin many cases deleterious. This unste'adiness is especially marked in installations of a temporary -nature, where it is impracticable to install large equalizing tanks, as is for instance the case in erection work for buildings, bridges or field repair work, etc. Work of this character is invariably done with small portable furnaces and these furnacesa-re usually handled by men who are not skilled firemen. It is, therefore, desirable to have a burner construction which is especially adapted for such work andhandling and in order to meet the furnace conditions it is the object of my invention to provide a burner of small and" compact construction. Furthermore, in order to meetthe air supply conditions, to provide a burner which produces a steady spray when supplied with a pulsatmg air current. Furthermore, in order to. meet the conditions of handling, to pro vide a burner which is simple in construction, which can be easily cleaned if necessary and which does not need any re-adjustment when re-assembled after cleaning.
The F igures I, II and III of the accompanying rawing illustrate my invention;

rows. Fig. II is a top view of the burner body; the nozzles'beingremoved. Fig. III is a top view of the oil nozzle.
In the drawing 1 is the-- burner body, having an oil inlet 2, tapped as indicated by 3 to receive an oil supply pipe (not shown). The bore 4 communicates with-the tapped bore 3 and with the axial bore 5 which ,ends at the upper face of the cylindrical bodyextension 6-. The burner .body 1 has also an air inlet 7 tapped asindicated by 8 to receive'an 'air supply pi e (not shown) The bore 9 communicates with the tapped bore 8 and with the bore 10 which terminates in a circular groove 11, cut in the upper face of 6. The portion between bore 5 and the inner face'of groove 11 is srmewhat raised above the upper face of the body-extension and. forms an annular seat 12, whichis faced off accurately and at right angles to the axis of 6.
The body-extension .6 is provided with an external thread 13 which is engaged by an internal thread 14, cut in the lower part ofthe air n0zzle 15. .The part of theair nozzle above the thread is recessed. The recess has a cylindrical face 16 concentric with the threaded bore and an upper face l7 at right angles thereto and to the axis of thread. Above the recess face 17 is a chambered portion 18, which has an axial, inwardly flaring bore 19, which bore is joined by an outwardly flaring bore 20.
21 represents an oil nozzle, having a conical portion 22, at the base of which extends the circular flange 23 fitting the recess in air nozzle. Flange23 has a number of openings 24. The central portion of-nozzle 21 is extended somewhat below the lower face of flange 23, which extension is faced accurately and at right angles to the nozzle axis and forms the nozzle seat 25 against seat 12 on the upper face of body extension. The
center portion ofoil nozzle 21 is provided by a conical bore 27.
The burner in Fig. I is shown'with the 1 parts assembled and in working position.
twill be seen that a lower air chamber 29 is formed between upper face of body-extension 6 and lower face of flange 23, which is in communication through holes 24 with an i pp air chamber 30; the latter being formed by the upper face of flange 23 and the chambered portion 18 in air nozzle. The
of these chambers insures a steady presence working of the burner with a pulsating current of air. The air, passing through bore 10 into the comparatively largechamber 29, expands, thereby decreasing the magnitude of the pulsations.
i made to occur one half of a period later than those in, the lower chamber so that a maximum in the lower chamber would correspond with a minimum in the upper chamber and. vice versa. This has the effect of complete pressure equalization in the upper.
chamber, and thus a steady, non-pulsating current of air will emit from the annular I 25 opening bet'ween bore 19 and nozzle 22. This again will produce a,
steady current of air, steady, non-fluctuating spray by the mechanical action on the oil stream emitting from bore 28.
The cleaning of the nozzles in case of carbonization, or stoppage caused by impurities carried with the air or oil, can easwhich action detaches both the air and oil nozzle, simultaneously from the burner body. The original relative position of the nozzles, governing the efiective air outlet area, is not changed by re-assembling. the nozzles after cleaning, and, consequently the burner does not need any re-adjustment.
Having/thus described the purpose,'usefulness and working of my invention, I desireto secure by Letters Patent:
In an oil .burner the combination of a burner body, having 'a threaded cylindrical body extension; an. annular groove in the upper face; an air inlet and an air outlet in said ,burner body, the ing within the groove aforementioned; an oil inlet and an oil outlet in said burner body, ter, ofthe upper face, whereby an annular seat is formed; an air nozzle threaded to engage the threads of the body-extension, having a recessed seat and an outlet; and an oil nozzle having a perforated base flange fitting said'seat in the air nozzle and said annular seat on the body extension.
In testimony whereof I have aflixed my signature in presence of two witnesses.
