Application led February 19, 1918, Serial Ita-218,026. Renewed September 8, 1919. Serial No. 822,504.

To all 'whom it may concern:

Be it known that I, Enwooo H. Jnnvrs, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Liquid- Fuel Burners, of which the following is a specification. y f

The present invention relates to improvements in burners, particularly that type enrployed in the burning of hydrocarbon oils, particularly of heavy gravity.

The principal objects of the invention are to provide a constructionfhaving an iin- `Vproved burner cup, of the turbiiietype, ro-

tated by fluid under pressure, one having an 'improved fuel supply controllable at a' point within the burner cup, and 'one which 1s capable of ready swinging movement relative to the furnace opening.

To more fully comprehend the invention, reference is directed'to the accompanying sheets of drawings, wherein Figure 1 is av lan view, partly in section, of my improve construction.

Fig. 2 is a view in rear end elevation.

Fig. 3 is an enlarged detailed sectional view illustrating the mounting for the burner cup and fuel supply leading thereinto.

n the several views of the drawings, wherein like characters of reference designate corresponding parts. 1 indicates a suit-I able tubular burner tip at the discharge end 2 of which the side walls taper, as at 3, toward the opening 4. The opposite end of said tip is connected over one end of the opening 5 of a suitable hollow body or ftting 6, preferably f the elbow type. The other end of said openin 5 connects through a pi e 7 with a suitab fitting 8, divided by t e intervening wall 9 into passages 10 and 11, the passage 11 connecting with the pi 7, as in Fig. 2 of the drawings The m et ends of the passages and 11 connect throu h fluid tight joints'13 and 12 with suitab e connections or elbows 1i and 15, from which extend the feed pipes 16 and 17. A bracket 18, preferably of the U-sh e t pe, secured to a support 19, preferably t e mace front wall, mounts the structure through suitable studs 20 which engage the respective elbows 14 and 15, holding the same in upright position and permitting the divided fittinpr 8 to rotate between the same.

Thus it wi l be apparent that ne burner tip is capable of an easy swinging movement posed blades or venes 31 to and from the opening 21 in the furnace wall, as illustrated in dotted lines n Fig. 1

of the drawings.

Disposed concentrically within; he tip 1 and body 6 and terminating short of the converging walls 3 of the'tifp i s afuel feed pif-e 22, the rear end wlii h asses through the wall of the body 6 an con- 23, couplin The outer end of thepipe 22 is reduced,

as at 27, and mounts'a pair of annular bnl] bearings 28 separated by a spacer 29,

' said bearings being retained on. the pipe by arnut 22.

. Secured to the outer collar of' the bearings 28 is a sleeve 30 having radially disarranged circumferentially thereof, with their a-n'gle to its axis of rotation and short of contacting with the wall of the ti'p 1. n

Threaded to the outer end of the collar is one end of a suitable burner cup 32 outwardly la'ied toward its discharge en and proJecting a slight distance beyond the end of the burner tip, as in Fig. 3 of the drawhe outer` surf of the dischar the cup 3:2 is ofa iameter sli htly ess than dint of the opening 4, therby providf an annular passage intermediate the cup 32 and opening 4. -A suitablenu, 33, threaded onto the pipe v,22 in re o' the bearings 28, mm'enient ,o

terminating the inner-surface o the bearings on said pipe, and said nut is ormed with a forwardly extending flange 34 for projecting o'ver the rear flanged 4edge 35 of the sleeve 30, thus pro riding a running (it 'for the rear edge of said ,callan Lubricant is sup lied to the bcaijigs 2S through a pige 35 and cup 36 contee cd therewith, sai cup being arrzlui ed exteriorly of the body 6.

end of' revcnts reasward lo" "tudinal ios ' l he discharge end ofbthe pipe 22 terminatos adjacent the rear and the disclurrge of the the cup is controlled hy a valve member 3s seutirz'f over the end of .said pipe. The valve 1s capable of movement. to seul; over 0r lift from the pipe emi hg; u controllingr rod 3S of small diameter, reminding longitudinally within Suid pipe and proJec-ting ut itu rear ond through the musing 24 of the D globe valveV type and with which it has threaded connection. ,fr handle 39. ou the end of said rofl permite of' rotation of the same to operate said vulve The valve meusber 3T ifi-vlfr-ihly unical in shape wzl a h its small emi or apex extending into said pipe, m that the fuel stream issuing from Suid' i e under sligluJ pressure will he defleote oy the walls of said valve outwardly in an even stxeam eircumfereutially thereof Onto the inner Wall of the burner cup.

The apparatus operates in the following 4imrnner: The pipe 16'is connected to a source of fuel sup ly, under pressure, and

und of the cup r'. fuel therefrom into pipe l? is' prefere ly connected to an air y suppl)1 under p1' usure. However, steam ma)r be employed if desired. The air under pressure passing through Athe body 5` and tip 1 strikes the blades o1' venes 31 musing a rotation of .the cup, the air or steam after o pussn from the blades or varies: folloh's throng' i the tip between the outer wall of --ihe cup and the innery wall of said tip, clischa'rgiug' from' thel tip through the pace beteren the end of sai( up und the surface Qof the. opening 4. The unseating of the `vulve 37 permit-s the fuel underjvn'essure to .dit-.hergecrcumferentially from the end of I `lthe pipe' 22 onto the, inner surface of the ilrapdly 'rotating cup 32, thv ventrlfugal lfdrceoiwhich, owiu r to its rotation, causes ,the oil tapas in a tuin film longitud'mall51 bfthe Baring walls thereof, and to` di:=

rharge radi-alli' from theeml thereof in the form of small globules and at a direction substantially al right angles to thL` path of the etroam of air or steam surrouiuling the cup. Thus oil is thoroughly intermixed with the steam or air on leaving the burner lip, insuring a highly combustible mixture.

By uontrolliuff the oil eedv'at the discharge end of theoil feed pipe, und at' u point within the burner "up, the drip or any rie` al. the time. ai shutting o' the oil flow, will he heilen-ged from the cup prior to the same arriving at a pointV ofvrest, as the {sup- \\'ill Spin 0r rotaie after the feed nf the :emailing medium therefor iS shut oil'.

In testimony whereofl have signed my mime to this specifeatlon iu the presence of a subscribing witness.
