Description

Patented June 24, V193() FRAN-K A. HOWARD, or ELIZABETH, NEWlruraissin?,V LAss/rencia imo 'sTANnAEnoaL DEVELOPMEN COMPANY, .A` CGBPO-RATIONQF @EDAWA'RE i* :DWELLING HEATER Yf1 lvsrALriArjIo1r rlhis invention relates to dwelling heater installations utilizing liquid `fuels and comprehends broadly the combination of a burner for liquid fuels, a means for compressing gas operated inconjunction therewith, a reservoir for liquid fuel and an air lift to trans-A fer fuel from said reservoir to a smaller recep tacle from which the burner is directly supplied.

rlhe drawing is a diagrammatic vertical Vcross sectionof a preferred embodiment of air'or any othermaterial gaseous at ordinaryl temperature. "Preferably, burner 2 operates through the atomization of a liquid fuel'by means of a compressed such asair or recycled flue gas; 'the motor and compressor are preferably designed for this purpose and operate'when gas is required for atomization.

lf the motor and `compressor are not re'- quired for this purpose, they may, neverthe- Vlo less, be adapted to operatey simultaneously i with the burner.

A supply of fuel'for the burner is retained in the storage tank 6, vpreferably ,underground," which may be refilled by means of pipe 7 terminating at Vthe ground leveland sealed bythe vented removable plug 8. Thev liquid hydrocarbon fuel flows from '6 through pipe 9 into the sump 10 covered by plate 11'. The storage tank 6A 'and sump 10.V formto#` gether the Asource `of oil supply for there.- Y ceptacle 18 situated at the higher level. .The

pipe 12 projects downwardly into nthis sump and at the other `end discharges into the re` ceptacle 18. Compressed gas required Vfor the operation of the burner is carried to control mechanism 3 vby means of pipe 13 con# trolled by valve 14. ik part of the-gas is div verted by means of pipe 15 controlled by valve `16. This pipe is provided with bend 17 or equivalent device such as a check Valveto 50 prevent the liow oflfuel by gravity'into the compressorlw'hen lnot in operation. ffthe i' motor andcompressor areinot required for Vthe yoperation, ofthe burner'but are adapted to operate.simultaneouslytherewith, the pipe 13 may be dispensed with and sealed off.

The pipe ldischarges'the compressed gas into pipe 12 in sump l() or into such relationshipv theretothat a mixed column of gas and oil is'formed in pipe 12 of lesser hydrostatic i head than the column ,of oil in the sump,` thereby causing a transfer lofoil to the receptacle 18, The' pipe 12 terminates within theV receptacle 18L in the floateoperated'shuto valve 19 whereby the amount y"of oil introduced may be restricted to that necessary to maintain ade'finite levelA in 18. Gas entering `with the "oil maybe vented through the pipe V19V controlled by valve 20. lThe floatv oper-v ated shutoif valve `maybe dispensed with in I which event any excess of oil over that neces- 1 sary to maintain the desired level-in 18 returns through pipe 21 controlled by 'valve 22 communicating with thereservo'ir. The pipe `23 controlled yby'valve 24 connectswith the receptacle 18 at or nearthe lower part therej of and conducts liquid fuely byV gravity to the burner control mechanismv 3 by which it is supplied tothe burner 2.

ItV will be understood .thatthe equipmentv shownis `in Villustratitm and, not` in limitation and, that variousalterna-tives maybe adopti' ed within the' scope of the' appended claims" `in which it is myV intention t'oclaim broadl all novelty inherent in the invention. Y

Iclaim; Y

1.,.An oilsupply system for Voil burners VVcomprising a source ofl oil supply, a recepta-V cle atk a. level above the source lof deliveryA pipe extending into the supply adjacent the'bottom thereof and comsupply a `municating with the receptacle, a Source for supplying gas under pressure, means for discharging gas from the source of gas to the delivery pipeadjacent the llower end thereof and beneath the level of oil in said oil supply sourceywhereby a mixed columnV of'gas and oil 'is formed in the deliveryV pipe of lesser `hydrostatichead than the column of oil in the oil supply source andtheoilfis caused to flow` to the receptacle, and a pipe to Vconduct oil source vof v y Vluy gravity from the receptacle to the burner.

2. Apparatus according to claim 1 in which the source of oil supply comprises an oil reservoir a sump into which the delivery pipe extends, and means allowing the passage of oil from the reservoir into the sump.

3. Apparatus according to claim 1 in Which the receptacle is provided With a vent pipe.

4. Apparatus according to claim 1 in which a pipe connection is provided to allow the return of surplus air and oil from the receptacle to the source of oil supply above the oil level therein. v

5. Apparatus according to claim 1 in which a float operated valve is provided in said'receptacle to control the fuel introduced in relation to the level of fuel therein. FRANK A. HOWARD.
