OF JULIET, ILLINOIS, ASSIGNOBS 'I'O GEN- J'OLIE'I, ILLINOIS, A CORPORATION OF ILLI- OIL-BURNE'B. SYSTEM.
Application filed June as, 1924. Serial No. 722307.
To all whom it may concern Be it known that we, FRANK STRnrcHand ,PAUL B. STR'EIGH, both citizens of the United States, and residents of J oliet, Will County, and State of Illinois, have invented certain new and useful Improvements in Oil-Burner Systems, of which the following isv declared to be a full, clear, and exact description.
1 This invention relates to oil burner sys tems and. among its objects are; to increase the efliciency of oil burners and to eliminate almost all, if not all, of the objectionable features now common in oil burner s stems.
Another object is to eliminate the co lection of carbon deposits on the burner; another ob- 'ectis to prevent the oil from flooding the asement of other enclosure 'in which the burner of the system is contained, such flooding usuall being occasioned by the escape of unlit 011 from the burner. Another ohjectis to provide an air blast for aton'lizing the liquid fuel and for creatin suction for feeding the liquid fuel to the urner. An-
other object is to provide a system in which a small quantity of the liquid. fuel is constantly kept at a predetermined level and fed for stopping the compressor in case the fuel escapes from' the burnerwithout being lit.
Anotherobject is to provide an automatic alarm which sounds in case the fuel escapes from the burner without being lit. A other object is-to provide an auxiliarv tan for storing a quantity' -of liquid fuel and a fuel reservoir for containing a constant but small uantity ,of'oil and "from. which the oil is eddirectly tothe burner, in combination three.wa "i et:.valve mechanism located in the auxi 'ary tank and connected with a main fuel tank and with the pump and ar ranged to'establish communication between the ,pump and main fuel tank when the fuel in, the auxiliary tank falls below a predetermined level and to shut oll communication' between the main fueltank and pump and establish communication between the suppl of fuelin the auxiliary -supply tank and t e pump when the level in said auxiliary supply tank reaches a predetermined level, whereby one pump only may be used for supplying fuel to the auxiliarysupply tank and. to the reservoir. Another object is .to obtain an even distribution of the flame from the centre of the fire pot. Another object is to prevent the escape of oil. or other .liquid fuel except when atomized and ignited. I
Other objects and advantages will occur in the course ofthe followin specification and with all of the said ob ects and advantages in view this invention consists in the several novel features of construction, arrangement and combination of parts, hereinafter fully described and claimed.
The invention is clearly illustrated in the accompany ng drawings, in which f Fig. 1 is. a ront elevation of an oil burner system embodying the preferred form of the present invention and showing its application to a furnace; Fig. 2 is a View partly in plan and part] in horizontal section,-of the I parts seen in ig. 1,. the line of section beng indicated at 2- 2 in Fig. 1; Fig. 3 is a -vertical cross sect-ion. taken on the line 3--3'of Fig. 1; Fi 4 is a detail, vertical I cross'seetion of tlfe. urner and burner tube 'takenon the line 44 of Fig.v 3; Fig. 5 is a detail, vertical, lon 'tudinal section of the burner taken on the inc 55 5 of Fig. 4; Fig. 6 is a detail plan of a unit comprising the liquid fuel and air pumping apparatus ;which forms part of the invention; Fig. 7 i is a detail, vertical section taken on the line 7--7 of Fig. 6; Fig. 8 is a detail, vertical section taken on the line 8 -'-8..of Fi 6;. Fig. 9 is a detail, vertical section 0 the float controlled. three way inlet valve shown in Fig. 8, the line of sectio'n'being indicated at 99 in Fig. 8'; Fig. 10 is a detail vertical section taken'on. the line 10-10pf Fig. 9; Fig. 11 is a plan ofa certain switch mechanism for stopping the motor which drives the air compressor and oil ump; Fig. .12 is a detail, vertical section ta en on the line 12-12 of Fig. 11; Fig. 13 is a detail, vertical section taken on the line 1%13 of Fig. 11; Fig 14: is a diagrammatic view of the motor control circuit and, a certain bell ringing circuit; Fig. 15 is a detail, vertical preferred embodiment of the invention, the
. and in the operation of the system act to atand omize the oil and direct the spray in a down-- ward direction. The tips may be made separate from the body 27 and secured therein by threaded connections. Connected with the compressed air tip 29 is a compressed air pipe31 and connected with the oil discharge tip 30 is an oil supply pipe 32, both of which lead through the hollow of the burner tube 24 and out through a plate 33 which is secured upon the open outer end of the burner tube. The compressed air pipe 31 leads from a compressed air tank 34 (see Figs. 1, 2, 6, 7 and 8) and the oil supply pipe 32 eads from an oil reservoir 35, which tank and reservoir comprise parts of the operatmg unit which controls the supply of compressed air and oil to the burner.
'A pilot light is used for igniting the fire 1n accordance with one form of the invention, the pilot light is supplied by a gas pipe which leads as usual from one of the gas pipes of the building. The gas pipe 75 leads into the furnace below the burner tube 24 and terminates below and at one side of the burner 26.
The operating unit, in its preferred form,
is secured, an outlet port-54,
comprises a base 36 which is in the form V of an auxiliary oil tank covered by the drip pan-37 having a bottom that slopes downward towards the middle of the top of the tank, where it is formed with an aperture 38 through which any oil-drippings may reenter the auxiliary oil tank 36. Above the auxiliary oil tank 36 is a base plate 39 which is mounted upon posts 40, (see Fig. 8) that are-threadedly secured in the cover 37 for the purposes of adjustment, and coiled compression springs 40 are interposed between the base plate 39 and posts 40 to take up vibration and eliminate objectionable noise. Thecompressed air tank 34 andoil reservoir 35 are mounted upon the base plate 39 and are bolted or secured thereto or in any other suitable manner.
Mounted on the base plate 39 adjacent.
the compressed air tank 34 is an air compre'ssor 41 (see Figs. 6 and 7) which has a discharge pipe 42 that leads into the com pressed air tank 34, and, as a preference, has a downwardly inclined discharge end 43. The air intake for the'compressor is seen at 44. For the purpose of lubricating the air comprwsor 41, the compressed air tank 34 contains'a quantity of lubricating oil and an oil fed pipe 45 is submerged in thelubrieating oil and leads from said tank to the.
inlet side of the aircompressor, where it is provided with a valve 46. The arrangement is such that when the valve 46 is opened, the air compressor draws in lubrieating oil which lubricates the parts of the air compressor and is discharged back into the compressed air tank 34. The compressed air pipe 31 is shown as entering the top of the compressed air tank in Figs. 6 and 7.
Mounted on the base plate 39 adjacent the oil reservoir 35 is an oil pump 47 (see Figs. 6 and 8) which has a discharge pine 48 that discharges into the upper end of t e oil reservoir 35. The inlet or oil supply pipe 49 of the oil pump 47 leads down into the auxiliary oil tank 36 and its lower end is connected to a float controlled, three way inlet valve 50; said ,valve 50 is also connected to an oil supply pipe 51 which leads from a main oil supply tank shown at T which may be located outside of the building in which the furnace is contained. The purpose of the float controlled, three way inlet valve 50 is to enable only one pump 47 to be used. for the'purpose of replenishing the supply of oil in the auxiliary oil tank 36 and for supplying the oil reservoir 35 with oil. The construction of the valve 50 will nowbe dc scribed.
Referring now to Figs. 8, 9 and 10 the valve casing 52 of the valve 50 is preferably Lil cylindrical in form and has an inlet port 53 v in which the end of the oil supply pipe 51 1n whichthe oil supply pipe 49 is secured and an inlet port 55 through which oil may enter; the
. valve from the tank 36. Rotatively mountstem 60 which valve casing and issecured to an arm 61 of and pumps oil (therefrom directly ed in the valve casing 52 is 'a hollow valve body 56 which 'isformed with inlet ports 57, 58 and an outlet port '59. The arrangement of the ports is such that at a certain position of thevalve body 56 the ports 57, 53 ma register, while the ports '58, 55 are out register and vice versa,; while the ports 59, 54 are always in registerrx. In a 'certain position of the valve body the ports 57, 53 and 58, 55 may partly r ister (see Fig. The valve bod" 56 as a projects out t rough the a float 62. In the operation of this float controlled,-three' wayinlet valve, when thei 1 oil reservoir 35. When the level of the oil in the tank 36 rises to a high point, the float is raised, thereby moving thevalve body 56't0 a position where the ports 57, 53 are out of re 'ster and the ports 58, 55 are in register, t e result being that communication between the main supply and-the pump 47 is I shut ofl:' and the pump 47 pumps oil directly from the auxiliaryoil supply tank 36 and into theoil reservoir 35.
In'order to obtain the beneficial that we have with this system, a termined, com aratively small uantity of oil is constant y maintained is sufficient to maintain the desired quantity tive of the amount that is used in the or head ofoil in said oil reservoir, an overflow opening63 is provided in one wall of the reservoir-35 which overflow plpening 63 opens into a chamber 65 of the o' reservoir structure, from the bottom' of which leads an overflow pipe-66 that enters the auxiliaryoil tank 36- through its cover or'did 37. It
is obvious that in caseimoreoil enters the oil. reservoir 35 than is used by' theburner, the surplus ove'rflows'through the overflow o ning 63 into the chamber 65 and disc rges into the auxiliary oiltank 36 b way ofthe overflow pipe 66. The oil supp y apparatus just described provides simple-and eflicient means whereb a su ply of oil is always maintained in t e aux laly oil tank, and a constant, relatively small quantity of oil is maintained inthe oil reservoir, lrrespective of the quantity of the oil used by results" predee oil 'res-. ervoir 35.

For the purpose of distributing the flame evenly towards the sides of the fire pot, a horizontal baflie plate 70 ,(see'Fig. 3) is provided below the burner. Said plate is mounted on a stand 71 havin feet 72 in which are adjustment screws %3 that rest on the bottomvof the furnace. By roperly setting u thescrew's 73 the bafile plate may be broug tv to a to the-burner. Extending u a curved "shiel proper height with respect from the baliie plate 70is 74, which forms a support for the inner end of the burner tube 24, and
also directs a portion of the aseousmixture upwards and across the; p11ot'light jet thereby insuring the immediate ignition of the fuel when it issues from the burner. I
Conveniently, an electric motor 67 is employed fordriving theair compressor and.
oil pump. The motor is' mounted on the base 39 and connected to the air compressori-and-oil -pump, by a belt 68 trained around pulleys 69,, 69*"011 the motor shaft and air compressor shaft, the latter shaft being conveniently connected to the oil pump shaft by a shaft coupling. Usually the circuit to. the motor is controlled 'by a thermostat, whereby the operating unit 0perates -when' the temperature in the place heated, falls below a predetermined temperature and ceases to operate when the temperature rises above the predetermined point. As soon as the electric current is shut oil, the motor sto s, and therewith the air compressor and oi pumpstops,'th e air pressure in the compressed" air tank and compressed air pi d'ro s to atmospheric pressure, andthe ow 0 oil to the burner ceases. When the motor is again started the pressure" in the compressed air'tank and compressed airpipe is restored and the oil automatically stopping the motor in such cases, and for simultaneously sounding an alarm will now be described.
' At the edge of the baflle plate 70 is a utter 76 (see Fi 3) into which unburne oil flows, and lea ing away from saidgutter is 4 a post 84, mounted on the stand 81 between 83 is connected to the lever 82 by a link 86.
the two switches 7 9,80 and it-has two arms 85, one 9f which is connected to the motor circuit switch 79 and one to the-bell circuit switch 80. Each arm 85 is connected to the blade of-a switch 79 or 80 (which switches are knife switches) bya link 85. The cup The arrangement of the automatic switch mechanism is such that, normally, the motor circuit is closed and the bell circuit is open. When unlit oil escapes. from the burner, un-
' der the influence of the atomizing action of the air jet, the oil flows out through the overflow pipe 77 and discharges into the cup 83. As soon as the weight of the oil therein overbalances the counterbalance of the lever 82, the lever is swung down by the filled or partly filled cup, the motor circuit switch 79 is opened, thereby shutting off the passage through the overflow current to the motor and the switch 80 of bell ringing circuit is closed, thereby warning the occupants of the building that the pilot. light, has become extinguished and that the operating unit has ceased to function. After the pilot light has been lit the cup 83 is emptied and the counterweighted lever 82 is thereby restoredto normal position, the motor circuit closed and bell ringing circuit is broken.
In the alternate form of igniting means, shown in Figs. 15, 16, 17 a spark plug device 90 is provided at the end of the burner tube 24 and the wires therefor are enclosed in heat insulating conduits and lead out through the front end of the burner tube.
A current of. electricity is passed through the terminals of the spark plugs for a short interval of time whenever the motor is started and the current is automatically shut ofi at the end of such interval of time. A simple means for accomplishing this result, comprises an electric switch mechanism 91 mounted on the top of the oil reservoir,
The operation of the system is readily.
apparent. When the motor is at rest, the air compressorand oil pump are at rest. As soon as the motor circuit is closed the motor is started and therewith the air compressor and oil pump. Air is compressed in the compressed air tank and a blast or jet of air is discharged across the oil discharge tip of the burner, and oil is drawn-out of the oil supply burner pipe, atomized and discharged downward in a spray, which is i ited by the pilot li ht. Air is drawn t rough the burner tu which tends to keep the tube, and the air and oil supply pipes cooljbesides supplying air to the burner at the point of combustion, this air supply also tends to prevent ,carbonization of the burner tips. ally by the baflie plate, causing an even distribution of the heat. As the oil is withdrawn from the oil reservoir, the head of oil The flame is deflected radi-.

When the current is shut 01f from the motor, the latter and therewith the air com;-

the oil, discharged by the burner, flows into the cup of the automatic switch mechanism,
