- Thepresent inventionrelates to. improvements1no1l burners and has-for itsprin cipalobject to provideaf burner structure for association with a boilerfor heating .5 water, the steam'generated in theboiler being partially 'mixedgwith the supply of oil-- and air,'wh'ereby to obtain proper atomizationof the fuel; r a v r A further object is to provide an oil 10 burner of the'labove mentioned Character which includes a means for regulating the fiow'of'oil'to the' burner head aswell as regulating the supply of steam, the burner 'head terminating at a point above the fire box of the boiler and extending into the fire box is a burner flue for directing the flame from the boiler head into the'fire box and p onto a flame spreader, v i i A'still further object "is to provide anoil burner of; the above mentioned Character,

which will, at 'all times be positive and efficient in its operation, the same being further simple in construction, inexpensive, strong anddurable, and further well adapted to the purpose for which it'is' designed.

i y In the -;drawings, wherein :for'the purpose of illustration is shown the preferred embodiment ofmy invention the numeral 1" designates generally a; boiler structure, the same; being provided with. a removable top 2, andprovides a closure for the; fire box e0 3, the water jacket 1 surroundingthe fire I box. A cold water inletpipe 5 extends intov the jacket 4 and a hot water'outlet 6extendsfrom thewater jacket through the side of the boiler, and has communication withare-v c5 ceiving unit 7 from whichextend's a heat.

p Additional heat pipes may-also extend from this-unit.- These heat pipes extend'into the various rooms ofabuildingfor heating the same, i in the manner well known the art.

A plurality ofsteam generator unitsfdesigna-ted generally/by the numeral 9 ;are a'rranged. vertically in the firebox 3 of the- F boiler 1, inannular spaced relation with re- -sp'ectyto each other, as more clearly illus:

shownat'15. The water will be supplied to this particular' steam 'genei at-ings'uiiit by gravity, due to the height at which the tank 13jisjarrang'edj i a a I g Y i e' her s eam generator-units" 1 m; we

their water delivery pipes 12 extending downwardly from the high pressure water supply,

for controlling the supply 01 water to the steam generator units.

7 A steam receiving jacket?" has communi cation with one of the steam generator units.

9 through the medium of the pipe'6', and'a steam outlet pipe 8 extends upwardly from the jacket 7. i

. A burner flue is supported at its upper end in the center portion of'the top 2 and he .steanrgenerator units 9 are disposed around. this burner flue. This burner flue extends downwardly into the tire box 3and terminates in spaced. relation with respect to the central portion of a flame spreadernn-it 21, that rests in the bottom ofthe lire box.

The flame-spreader consists of a circular disc ofsuitable thickness that is formed on its upper and bottom faces with the corrugations 22, that extend radially from a fiat central portion 23, as more clearly disclosed in Figures 6 and 7 of the'drawings. lug or baflie 24 is formed on the upper faceflofj 1 inchn-etrpipe 4:3 that isarranged lll'tllc fire this disc like member. 4

The oil burner further includes the, pro vision of'the burner head th at consists of a cylindrical shell 25,.Op6I1 at its respective ends. I A closure-plug 26 is threaded in the upper end of the shell whiledetachably secured in the open lower end of the shell for disposie tion directly over the open upper endof the,

burner fiue'20 is the nozzle or burner tip27.

A nipple 28 is formedon oneside shell for 1 communication therewith and the bore of'the this closure isformed with a central threaded opening for receiving the outlet end of an oil deliverypipe 30 that has communication with an oil supply tank 31, also arranged above the burner head and toone side thereof, whereby the oil will be fed to the burner head by gravity. A manually actuated valve 32 isarranged in the delivery pipe 30 for regulating the flow, of the oil from the tank 31 to the burner head, anda check valve 33Iis also arrangedin the horizontal portion of thedelivery pipe, to preclude any possibility of the flames reaching the oil supply tank.

The'cylindrical shell 25 of the burner head is formed with suitabe air inlet 0 enin s 3.4

in the intermediate portion thereof, and extending downwardly through the closure plug 256 into the shell is a steam delivery 2 tube or relatively small pipe 35, the lower'end of this steam pipe extending into the nozzle .or burner tip27, in the manner as clearly shown in Figure 4 of the drawings.

' Steam is supplied to the pipe 35 through the supply pipe 36 that extends upwardly from a steam'chamber 37 that is associated V i with one of the steam generating units 9 for disposition above the top 2 and this particu lar steam generator unit has the'water supplied thereto from the-tank 13"through the pipe 1 1- in the manner heretofore explained.

A branch pipe 38 aifords communication between the intermediate portion of the vertical supply pipe 36 and the upper portion of the delivery pipe 7. 35, and the usual fittings or couplings are associated with the pipesto. as?

semble the same-together in communicating relation. I ,1 V a :The safety check valve unit,zdesignated a. generally by thenumeral 39 is-associated'v'vith the upper exhaust end of the vertical pipe A steam pressure gage 40 is arranged on the upper-end of the delivery pipe 37. Asteam gage 41 1s ISSOCIQt-Gd with the heat pipe 8 and a thermometer 42 is associated with the] heat pipe 8, as clearly indicated in Figure 1.

The invention 7 further comprehends the provision of a smoke consumer, andthe same Comprises a rearwardly extending upwardly box 3, the forward lower end of this pipe com municating with the lower e ndportion of the 7 burner flue 20 by means of the fitting shown at l i in Figure 3. A smoke flue 45 extends upwardly from the rear. portion of the boiler and has communication with the upperend of the pipe 13. A smokepassage i l8'is formed n the side of the fire box '3 adjacent its top for affording communicationbetween the fire box and the smokechamber 49 that extends around the water jacket. i r V J damper 46 is arranged in the smoke flue 45 as indicated in'Figure 2. ,The top 2for the boiler 1 is formed with an opening where '1' by access to the interior of the fire box may be had, and, this opening is normally closed by means of the hinged door 47.. w

In. operation,water is supplied to the several units 9,:'and-oilissupplied to the burner head through .the delivery pipe 30.

the ire box, so that the flame will be directed radially to heat the steam generator units 9. Any appropriate means'may be provided for either automatic or manual actuationto control the-supply ofthe oil and steam, such as is well known in the art.

9. through the provision of the heat pipes 8.

Itwill thus be seen from the foregoing description that lhave provided an oil burner for use in conjunction with a boiler which will, at all times, be positive andeflic'ient, in

its operation and by admixing steam and air with the fuel, the operation of the burner will I bevery inexpensive; i

. It will also be observed that a relatively largeamount of oil is delivered to the burner tip or nozzle, whereas a small amount of steam is suppliedto the burner head, whereby to obtain a relatively strong flame.

The parts comprising the oil burner are so arranged as to render the same readily and easily accessible for adjustment or disassembly. a

The boiler is for hot water or steam, and the steam generators 9, inside the firebox can be used for hot water or steam,- whereby two systems can be heated at the same time, also one generator unit may be used for a: hot 0 water tank. r Having thus described my invention, what I claim as new is: v I r s 1. In combination, a furnace provided with the burner this, and a flame spreader arranged v beneaththe lower end of the burner flueand steam generator units for effectingtheheatin'g of said units, means for supplying steam generated in one of the units to the burner head,

as and for the purpose described. e

In combination, a furnace'provided with anopen top fire box, a cover therefor, a'burner flue open at its respective ends, and extending downwardly from the cover centrallyofl the fire box, a burner head positioned directly above the burnerflue whereby the vapor. of the burner head .willibeprojected down-. wardly through the burner flue, a flame spreader arranged beneath t-he-lower'end of the burner flue, and a smokeconsumer unit connected with the lower end of the burner; I

flue comprising an upwardly extending pipe communicating at its lower end with the low:

er end of the burner flue, the upper end of the pipe extending exteriorly of the furnace for,

communication with a smoke flue.
