OIL BURNER Filed Jan. 16, 1928 2 Sheets-Sheet 2 ill Patented Feb, 23, 1932 UNITED STATES PATENT OFFICE MILTON A. IEESLER, 0]! LOS ANGELES, CALIFORNIA, ASSIGNOR TO PETROLEUM HEAT 8: POWER COMPANY, OF NEW YORK, N. Y., A CORPORATION 'OF DELAWARE OIL BURN Application filed January 16, 1928. Serial No. 246,937.
This invention relates to an improvement in oil burners and has for one of its objects, the provision of an improved type of apparatus in the oil burner industry which is adapted for both domestic and commercial installations.
Une of the objects of my invention is the provision of an oil burner apparatus in which the oil is fed to the burner by high pressure air, a valve forming a part of this invention being provided for controlling this air, while another object of the invention is the provision of an oil burner in which the oil level is automatically controlled by a sin 1e float.
11 general, the present apparatus provides a blower of the multi-stage type, that is to say, a blower so constructed that air at difterent pressures is delivered therefrom, the low pressure air from this blower in the present apparatus supplying the secondary air to the burner for supporting combustion, while the high pressure air delivered from the blower is employed in the present apparatus for efl'ecting a flow of oil to the burnor nozzle and supplies the necessary air for driving the air turbine by which the atomizing cup or other rotary type of atomizer is actuated.
Other objects of this invention will be developed as this description proceeds.-
In the accompanying drawings wherein an embodiment of myinvention has been illustrated,
Fig. 1 shows the same partly in section and partly in elevation;
Fig. 2 1s a part sectional view illustrating the port structure by which oil is conducted to the burner;
Fig. 3 is a detail of the float control valve mechanism by which the oil level is maintained properly;
Fig. 4 is a view on the line 4-4 of Fig. 3; and
Fig. 5 is a detail view of the improved air valve employed in my structure.
Referring to the drawings in detail, my improved burner comprises in general, a casing 1 in which is mounted the burner structure proper, that is to say, the primary and secondary air tubes, oil tube, turbine and atomizing cup. This structure may be similar to that disclosed in my Patent No. 1,595,931, and will not be described in any further detail. Oil is supplied to the burner from a feed tank 3 as will be more fully pointed out herein.
4 designates an electric motor for driving a multi-stage blower 5. This multi-stage blower is not my invention and has not been shown in detail for this reason, but it will be sufficient to state that the same comprises a low pressure stage and a high pressure stage, the low pressure stage supplying the secondary air necessary for supporting combustion, while the high pressure stage, as will be described herein, supplies air for the feed tank 3 and for driving the turbine of the burner. 6 designates an oil ump which may be of the gear type convemently driven by the motor 4. This pump is provided for the purpose of takin oil from a main su ply tank and pumping it into the feed tank 3 rom which oil is forced by the pressure of the air in this tank to the burnern Air for effecting a flow of the oil 7 from the feed tank 3 to the burner is supplied by the multi-stage blower 5 and enters the tank 3 through a port 8 in one wall thereof. The ressure of the air entering'the feed tank e ects a flow of oil out of the tank byway of conduits 9 and 10, valve 11, oil passageway 12 to oil passageway 13 communicating with the oil tube of the burner. 14; designates a yoke adapted to hold the burner tube 15 in place, the latter being provided with an offset or lateral extension 16 over which the yoke 14 is swung when the parts are in operative position. The yoke 14 also controls the valve 11 and when the yoke is in the position shown in Fig. 2, the valve 11 is open as illustrated, but when the yoke is swung to the dotted line position of Fig. 2 to release the tube 15 of the burner so that the same may be retracted, the valve 11 is at the same time moved to closed position. This arrangement is provided for pre venting the escape of oil to the exterior of the apparatus when the burner tube 15 is being adjusted or when, for any other reason,
' mounted on the shaft 19 of the motor 17 and the yoke 14 is swung to the dotted line position illustrated in Fig. 2.
An air valve illustrated in Fig. 5 in some detail is provided for controlling the pressure of the air on the oil 7 in the feed tank 3. A motor illustrated diagrammatically in Fig. 1 and designated 17 provides a drive for this air valve, the air valve comprising a cam 18 controlling a port 20 in the body of the Valve and which port communicates with the exterior of the valve body. A pipe 21 communicates with the interior of the valve body at all times and its opposite end is led into the feed tank 3 as indicated at 22. When the cam 18 is fully closed, that is to say, fully closes ofl the port 20, it will be seen that a pressure will be built up within the feed tank 3 and when the cam 18 moves off the port 20, this pressure will be relieved inasmuch as air may then escape to the atmosphere from the tank 3 through the pipe 21 and to the atmosphere through the port 20 of the valve. valve is intermittently operated.
The oil levelin the feed tank 3 is always below the level of the burner 2, the conduit 9, that is to say, the lower end of the conduit 9, however, being submerged in the oil in the tart. In order that the level of the fuel or oil in thejtank 3 may be promptly controlled, I have provided a float control valve mechanism automatically operable for this purpose. This float valve mechanism comprises a single float 23 pivotally supported on the valve body'B, and through an outlet 31 in the valve body and which outlet is abreast of the opening 27- just referred to. One I end of this rod is provided witlf a ball 28 which-makes a convenient means for attachin the arm 26 to the valve stem.
Initially suflicient oil is placed in the feed tank 3 to raise the float 23 approximately to the position shown in Fig. 3. At this time, with the float in this position, the valve 29 above referred to and which is carried by the stem 27 and located between the intake pipe or suction side 32 of the pump 6 and a main supply tank (not shown) is closed, while the valves 30 and 31 are, as will be seen from Fig; 3, in open position. Upon operation of the The motor 17 which drives this airburner and consequent operation of the pump 6 no oil will be drawn from the main supply tank but oil from the feed tank 3 will be circulated by the pump in a closed circuit, this oil passing through opening 27' in the wall of the feed tank, outlet 31 in valve body B, past the valve 31, suction side of the pump 6 and back to the tank again through the discharge side 33 of the pump. As the burner is now in operation the oil level in feed tank 3 will drop slightly, the float 23 will lower accordingly and the valve 29 be opened slightly. Under these conditions oil to satisfy the pump 6 will be drawn from the main supply tank past the valve 29 by the pump 6 and discharged thereby through pipe 33 to the feed tank 3 and at the same time some oil will be circulated in a closed circuit from the feed tank. Under normal operation the parts will remain in this position. In other words, the
oil level will remain constant, the float 23 will 31 all unseated will efi'ect an increased opening of the valve 29 and permit of an increased amountof ail to be drawn from the main supply tank and supplied to the feed tank 3 to bring the float back again to its proper or normal position. Should the oil level in the feed tank 3 drop-sufliciently or should the float 23 drop for any other reason, as for example should the float become leaky and fill, the stem 23 will be moved to the left as viewed in Fig. 3 positively so as finally to seat the valve 30 and close off the passage-31 by the valve 31 so that oil can no longer be supplied to the pump 6 from any source. I
It will be seen, therefore, that I have provided a single float for positively and directly controlling the three valves 29, 30 and 31, these threevalves being always at fixed distances apart, the valves 29 and 30 being located intermediate the suction line 32 of the pump 6 and the main supply tank, while the valve 31 is intermediate the suction line 32 of the pump and the feed tank 3. It will be seen also that inasmuch as these three valves are at fixed distances apart any movement of one valve will eifect a corresponding movement so far as distance moved is concerned of the two other valves.
It will be seen also that-under normal operating conditions all three valves are in open position and that upon any excess rise in the oil level with a consequent rise of the float 23 the valve 29 will. be seated and the valve 31 opened full to permit of the pump 6 being satisfied by oil pumped in a closed circuit out of the feed tank 3.
It will be seen also that a lowering of the float 23 due to a lowering of the level of the oil in the tank 3 or any other reason will open the valve 29 at the same time, gradually closing oil" the valve 31 and moving the valve 30 toward closed position, all of these movements being accomplished positively by the float, and should for any reason the float 23 reach an extreme low level, as for example due to leakage of the float or due to a leak in the feed tank 3, then under these conditions the valve 30 will be moved to closed position as well as the valve 31 so thatvno oil can longer be supplied to the pump 6.
As the oil burner is placed in operation, the pressure of the air delivered to the tank 3 from the blower mechanism 5 will, as above ointed out, effect a feed of the oil to the urner, the motor 17 being so arranged as to maintain the valve 18 in proper position to maintain the proper predetermined pressure of air in the tank 3. When the burner ceases operation, due to the temperature of the room or building being heated having reached the desired point, the motor 17 will operate to open the port 20 of the air valve thereby permitting the pressure in the feed tank 3 to drop, the opening of the port 20 placing the port 22, in other words, the interior of the tank 3, in communication with the atmosphere so that oil will no longer be fed to the burner. After resuming operations, the valve 18 will close the port 20 allowing pressure to build up in the tank 3 and the feeding of oil from this tank to the burner to be resumed. It will be seen, therefore, from the foregoing, that I have provided aburner apparatus in which the fuel is fed to the burner under pressure, this pressure being controlled by a valve adapted to operate so as to maintain the proper pressure in the feed tank and hence assure the desired feed of the oil to the burner, the oil level always being below the burner, that is to say, the level in the tank 3, which is the feed tank, always being maintained below that of the burner in order that the oil may not feed to the burner by gravity and perhaps flood the system.
It will be seen also that I have provided a float control for the fuel in the feed tank whereby a single float may be utilized for this purpose, this float being connected to a valve mechanism so constructed and arranged that when the level in the feed tank is too low, a supply of oil will be pumped to the feed tank and when the oil level reaches a predetermined level, the float control is operative to prevent this level rising to a dangerous point.
"What I claim is In combination a feed tank, a float therein,
a pump for supplying fuel to said feed tank, said feed tank being provided with an outlet to the suction side of said pump, three valves integral with each other and positively, directly and simultaneously controlled by said float, a pair of said valves closing in the one direction, the third in the opposite direction, one of said pair of valves controlling communication between the intake side of the pump and a main supply tank, another of said pair of valves controlling communication between said feed tank and the intake side of the pump and the third valve being adapted to interrupt communication between the intake side of the pump and the main supply tank with the first mentioned valve in open position.
This specification signed this 3d day of January, 1928.
