CENTRIFUGAL 01L BURNER.
APPLICATION FILED 0CT.24.19\6.
Patented Feb. 5, 1918.
m M, www] l fb all whom-t may Beit known that-l, MILTON A. lnsiiiinyaq llt) tt tu t.restituir citizen ofthe United States, residing at the `city and county -if SanlFranciscoand State 'of California, have invented new and useful linprovementsin Centrifugal @il-'Burners of which the following is a specification. 'llhis invention relates to a centrifugal oil burner. 7
` Une of the objects of the present invention.
is to provide a simple compact oil burner,
in which the-oil is atomized and projected in a forward direction `with relation to the burner by the combined action ofcentrifugal force and'air under pressure, and particulai-1y to provide .a rotating cup lof novel construction by which atomization of the oil Another object of the invention is to provide an. anti-friction bearing for the cup together with means for delivering oil thereto,
and also t0 provide -nieans for forcing air both interior and exterior of the cup and simultaneously rotating the cup.
Further objects will hereinafter appear. rfhe invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, having reference .to the accompanying drawings in which Figure 1 is a central longitudinal section through the burner.
Fig. 2 is a plan view of a portion of the atomizing cup showing the relative position of the stationary and rotating turbine vanes.
the outer end of which is secured an yatomizing cup- 8. Secured on the inner end of the tubular member 4 asat 9, is a pipe 1'0 which passes through the tubular shaft 'I and en- I tu @canoa or reu-erf retenu.

rlfhis pipe together with-the tubular nieniberA t being provided for 4the purpose of deliver-.
ing fuel oil to the cup. Formed on the extemor-surface of the' cup 8, or suitablysecuredftheretdis a plurality of turbine vanes 411, and secured within the nozzle just ahead -of the vanes-ll, is av plurality of stationary vanes 12, and adapted to deliver -air, under pressure to thejT fitting with connected nozzle 2 from .a fan blower, or other source. of
air supply, is a pipe 13. -lFornied inthe tions 14, and. formed integral with the cup andsurroun-ding said perforations isv an an'- nular 4rearwardly projecting Harige l5;V 'llhe rear end of the cup is a plurality of perfora` operation of the burner. will be aS follows-:-- l Airunder pressure'entering the l tting A with connected nozzle 2, will pass through thestationary vanes 12 and iin'pnge upon the vanes l1, causing these with connected cup 8 to revolve Aat a comparatively high' speed. @il is at the same time deliveredto the tubular 'member 4' through 'the rear end., and is then conveyed through the pipe 10 directly into the atomizing cup, where itis discharged by centrifugal'action. 'llhe hi h revolving ,speedy of the cup` produces su! cient centrifugal force to projectthe' fuel oiln inthe form ofa thin spray which is furtherl brokenup by the 'air discharging through the nozzle after passage :through the turbine vanes. A highl combustible mixture is in this manner proA uced by the `combined action of the centrifugal force and air under pressure andas the air pressure is s'uficiently great to overcome the centrifugal action of .the atomizer, it' will readily be seen that a combustible mixture consistin of oil, vapor and air, will'beprojected in a orward direction with relation to the nozzle. A considerable portionof the -air is Ialso caught by the annular rearwardly projecting flange 15 and forced through the perforations 14 directly into the cup, inthis manner supplying addii tional air through the center. of the cone shaped flame, which has proven a great benefit so far as combustion is concerned.
Running parallel with the tubular meniber fl is a lubricating oil supply tube'l'?. This is connected at one-end with alubricating cup mounted on the head 3, and the opposite end with an oil duct 18 formed in the bearing head 5 which delivers the lubricatlng oil directly to the anti-friction ball bearings shown. This manner `of lubricating the revolving parts provided is exceedingly eiiicient and reliable, as the well produced 1n the bearing head 5 permits the revolving parts to be amply supplied with a lubricant at all times.
The burner here shown is exceedingly simple and compact in construction. All unnecessary revolvingparts and bearings ,have been eliminated, in this manner reduc- The provision of the intake opening 13 shown, permits `a whole battery of burners to be quickly connected and laced 1n position under a single boiler if esired, and as each oil and air connection is provided with a valve, independent adjustment as far as each burner is concerned, may be obtained.
The materials and nish of the several parts of the burner may be such as the experience and judgment of the manufacturer may dictate.
Ifwish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, and that I do not wish to limit myself to the specific de- 4si or construction here shown. v
