shown in Figure 1 as being connected to a threaded member 11 which `constitutes part of the oil line 12. The nozzle 10 `(Figure 1) is disposed' within a semi-spherical hood 'A 13 having a Venturi-shaped discharge orifice Y 14. It .will be noted that the nozzle 10. is' lnormally positioned within the discharge orifice 14 of the hood 13. The tubularV member 11 is supported within the hood 13 by means of an extension 15 rigidly fastened to the hood 13 at'16. The hood 13 includes a tubular portion 17 `telescoped by an airpipe or sleeve 18 which is adapted to be secured to"V the portion 17 through the means of-thefsetscrew 19.
Extending through .the air tube 18 and into f vthe hood 13 are a pair of parallel angular or 'electrodes'Qu pointsfl"V i the hood 13l will force the spark into the fuel jet emanating-from"the nozzle 10. @IV sha-ll now proceedto describe'in'detail'the construction of mylnovel`` nozzle 10,11` y p 1 p The `nozzle 10 includes two'cooperating tubular members23`and 24. Member 24 com- -prisesl a reducedthreaded end 25 adapted to i be threaded Vinto-thentubular member V11, an
intermediate Lhexagonalfor nut'V portion 26, andV a threadedportion 27 adafpted to Abe screwedlintoa threaded `opening 2,8 in`nj1e1nberv23; [Extendingthrough the member 24 is a passageway29 whichterminates at onef end in' a.n"'1enlargedl or flared openingfl30 `threaded portion 28'.

The end portion -33 has alcentralopening 34 s which comprises the Vdi'schargeorifice"of the The reference character 10 designates gen'- erally the nozzle of my invention, which is nozzle 10. "f
The construction of the grooved member `32 is clearly shown Vin Figures A3, 4 and 5; This membenmerely comprises .a part of a cylindrical rod. This member 32 is pro?V K vided with a plurality of spiral teeth or iutes 35V, preferably four in number, on its outer.
veriphery.V Thesev `flutes are separatedV by Y p j'The 'member 23,in addition'to the threadp i e'd opening 28V, hasa somewhat smaller open-fH The operation of my nozzle is briey as follows:
The oil or other fuel upon leaving the pipev l2 passes through the tubular portion 11 into the passageway 29 in member 24.v This fuel Y is discharged from the passageway 29 into the flared opening 30 which allows the fuel to .enter the spiral grooves 36. The pressure oftliis fuel entering thefgrooves 36 is vof suf-l Y V icie'ntforce to cause thegniember 32 to impart a whirling action tok the fluid. This Vwliirlingr of thefuel results in the atomization of e Y the liquid fuel or oil prior to its leaving the discharge orifice 34 of the nozzle .10.
This whirling fuel is forced into Contact with thefrelativelyl sharp edge 33 ofend porf tion -33of 'member 23, whichcuts or breaks up the fuel, thusresulting. in amore conipleteiatomization ofthe fuel; vrThe fuel upon leaving the nozzley 10 is discharged into the stream of-air leaving the hood 13. and is ignited bythe spark of the electrodes 21.A g f Now, ofcourse, itis to be understood that although I have illustrated andfdescribed in detailthe preferred form of my invention, the invention is ,not to be thus-limited, but
onlyin so far as defined by the scope and Y spirit of the appended claim.
Y Y I claim as niyinvention:
In combination, in a nozzle, a tubular niember including a fuel discharge orifice defined by a relativelyvsliarp edge, a second member connected to and extending into said tubu ilarmember` andhaving a fuel passageway,
said second member including aiiared dis- Y charge orilicedisposed in communication with said fuel passageway, and a member mounted in said tubular member abutting said. second member adjacent said flared orifica-'said latter member'in'cluding a spiral groove. disposed at one end in communication with the outer periphery ofsa-id flared orifice and at its other end with the discharge orifice, in saidA tubular member, said flared orilice serving to direct the fuel into said spiral groove and said spiral groove serving' to atomize the fuel, said edge of the tubular member being beveled inwardly toward and in substantial alinement with the bottoni of n said spiral groove so as to cut the whirling fuelas it leavessaid groove.
In testimony whereof I have hereunto sub- `scribed my naine at Chicago, Cook County,
Illinois. f
