"A starting or'secondary burner 9 extends through an openin in the front wall of the. boiler 1, having a' urner ca 10 thereon of suitable design, whereby t e oil will be caused to thorpghly mixwithya supply of .P

air also delve to the burnerfin a manner which 4will be presently described, said .burner 9 being arranged'upon the. outer endof a conduit 11 extending from and supported by the lcasing of a rotary `blower112-fl6 al y indicated atv 13, the same, as shown in f the Figs; land 3, being; arranged u n a base 14 which in' turn, is adapted to fix.- edly connected Ato the particular support therefor, through the medium of bolts 15. Fuel forvthe starting or second burner heater 17 arranged upon a conduit -18'y tapped from the boiler 1, whereby the heated` water therein may vflow through the g same, such flow of water being regulated by j v means of hand valves 19. The freeeud of' the conduit 6 as shown in the Fig. 1 extendainto enuement with the lower portion of the tan a eater 17, embracin the vertical portion of the conduit 18, w lHeim-outlet conduit 20 extends from the upper end -of said heater and intojenagement with the upper end of van\oil fi teri tank` 21; a hand ,valve 22 bei preferab y interposed in said outlet con uit 20 for an obvious purpose. Extending for a distance into the top of'the tank filter 21 is a branch conduit 23 having a suitable strainer 24 arranged 'about the inner endl portion of the same, as

shown in the Fi 6, while the opposite end with the intermedia-te portion of the oonduit 11 extending from the rotary blower 12, thus rmittln vthe deliveryfof oil to said con uit 11 m whence it will be blown forwardlyl through the conduit by reason of the air inressure therein and thus broken up into forad'in'xture with the roper quantity of air, hereinafter more yf described.

As will be noted, the arrangement of the e combustible particles Il burner 9 is such as to 'direct the fiame emity ted therefrom into engagement with a cy- .lindrical retort 25, supported as at 26 at a position in proximityto said burner and extending through the opening in the forward wall of the boiler` 1, into the combustion chamber thereof, as clearly shown in the Fig. 1. By reason of the engagement of the flame emitted from -the burner- 9 with the lower side of the retort 25, the waterV contained within the same will be rapidly converted into steam, such water within the retort being sup lied thereto fromva suitable` feed pipe 2 lower end of the float valve controlled regulating tank 28 having an outlet conduit 29. connected to the .lower end thereof and communicating with. said retort, whilev a steam inlet conduit 29 is tapped into the reduced upper end of said tank, as shown in the Fig. 4, this latter conduit 29 extending into engagement with a pressure gage 30 which is su ported thereon for an obvious purpose. A so, a` sight gage 31 may be and preferably is arranged adjacent to the outer .end wall of the cylindrical retort 25 and as will be understood, communicates at its opposite ends with the samein order that the water level within the retort 25 -may be readily ascertained by. an operator.

A main burner 32 is provided and is arranged at a point adjacent the lower side of the inner portion of the cylindrical retort 25, being disposedso as to direct. the heating flame emitted therefrom .onto a portion,V of theretort 25 Within the combustionv chamber of the furnace housing, whereby to permit the constant generation of steam within said retort irrespective of whether the starting or secondary burnen'9 is emitting iam'e or not. This main burner 32 is pivotally mounted for horizontal move- 'ment upon abracket or pedestal 33 arranged at a point directly adjacent the outer side of the forward wall of the boiler 1 and communicates .with a branch fuel feedingv pipe 34 extendlng from the oil filteriner tank said conduit 34 for an obvious purpose.

As means for automatically controlling the amount of steam generated in the retort 25 by engagement of the heating flame emitted from the mainy burner 32 therewith, subsequent to the extinguishing of the heating fiame emitted from the starting burner 9, I

communicating with the provide a pressure controlled diaphragm 36,

understood that when the pressure of steam within the retort 25 exceeds maximum, a portion of the same will enter the diaphragm by way of the conduit 37, expand the same and impart a lateral thrust to the bracket arm by way of the free and movable outer end thereof, hence, swinging thevmain burner 32 outwardly and away from the4 retort for a distance suiiicient to either. discontinue the application of heat to the retort 25 or to accordingly diminish the same to meet with the requisites then' present.

The operation of the burner may bereviewed `as follows;

To start the improved burner, oil is admitted by way of the conduit 23` to the conduit 11 whereupon it will be mixed with an amount of air sufficient to create a combustible mixture, whereupon the .heated fuel .will be broken into small particles and discharged for ignition from the burner cap 10 of the starting burner 9. Because of the factthat said burner 9l is positioned adjacent the inner and lower side of the retort 25, the flame emitted therefromwill be directed into engagement with said retort and hence a portion of the water therein ywill be converted into steam. At this time, the valve 35V of the conduit34 is opened, admitting heated oil to the same for delivery to the main burner 32. At the same time, the valve 35 in theiconduit 34 is opened, permitting the steam generated in the retort 25 to flow through the same into the main burner 32 for admixture with the heated fluid fuel iiowing into the same. The pressure of the steam introduced into the main burner 32 .will be sufficientil to thoroughly break up,l

the fluid or liquid fuel and cause its discharge in an atomized and highly combustible state therefrom, whereupon the same is ignited. v,With generation of an initial quantity ofvsteam in the retort 25, the supply of fuel to the starting burner 9 may be' discontinued, thus extinguishing its heating flame.' Because of the positioning of the main burner 32 with relation to the lretort 25, a portion of the heatingiame emitted therefrom will bel directed onto an adjacent portion of the retort 25 and hence, will carry on the generation of steam therein sulficient to continue to `supply that quantity' of steam to the main burner 32 for creating a highly combustible mixture. Should an excessive amount of steam be generated in the lretort tion may continue.

expansible diaphragm 36, which in turn will be expanded and 'thus impart an outward lateral thrust to the arni 38 connected to the pivoted horizontally movable main burner 32, therebyr moving the -free end of' said burner outwardly away from the retort 25 so as to diminish or entirely discontinue the application of the heating flame to the retort 25, thus enabling the apparatus to maintain an even pressure in order that efficient opera- The supply of water to the retort 25, as hereinbefore stated, will be automatically controlled by means of the float valve regulating tank 28, so that when the level of water in the regulating tank falls below normal, the float of the valve will accordingly drop and thus move the valve to its open position for admitting an additional supply of water by way of the feed pipe 27 from whence it will be delivered through the conduit 29 to the retort.
