BURNER APPARATUS.
Application filed June 23,
To all whom it may concern:
Be it known that I, STANLEY R. HARD- WIGK, a citizen of the United States of America, residing at Toledo, Lucas county, Ohio, have invented new and useful Burner Apparatus, of which the following is a specification.
This invention relates to the control of fuels for combustion.
This invention has utility especially in fluid fuel burning installations.
Referring to the drawings Figure 1 is a view, with parts broken away, of an embodiment of the invention in an installation for heating purposes as for residences Fig. 2 is a detail view with parts broken gwsiy, of the air line control valve for the Fig. 3 is a sectional view of the air line check valve;
Fig. 4 is a longitudinal section of the car bureter,
Fig. 5 is a plan view of the carburetor;
Fig. 6 is a plan view of the heating coil in the furnace; and
Fig. 7 is a fragmentary section of the furnace showing the burner passage up through the furnace from the carburetor.
In the installation of the device of the invention herewith especially in connection with heating plants for buildings or residences, it is desirable to have the apparatus operate automaticallv. For instance a thermostat 1 may control a thermostat motor 2 for throwing in or out, an electric motor 3 which electric motor 3 may drive a rotary air pump 4. This pump 4 may have a by pass line as shown to control flow of compressed or power driven air in the air supply line 5 extending to tank or reservoir 6. This tank or reservoir 6 may have a liquid fuel as gasolene or kerosene oil therein, which is preferably maintained at a level above that to be shown in sight glass 7. In the lower region of this oil reservoir 6 is a screen 8 in communication by line 9 past a minute vent opening 10 near the top of the reservoir 6 with the oil or liquid fuel supply line 11. The flow of fuel in this line 11 may be adjusted by a valve 12 in addition to the adjustment by the pressure as varied by the bypass pi e at the pump 4 which has a regu lating va ve 13 therein. The working pres- Specification of Letters Patent.

sure on the tank 6 may be disclosed by the gage 14.
The air line 5 as a pressure air supply, besides extending to the tank or reservoir 6 has a portion 15 extending there-beyond, which portion 15 has a small branch line 16 extending to auxilia reservoir or housing 17 containing cylin er 18, with piston 19 therein, (Fig. 2), normally pressed downward by a spring 20, which position of the spring 20 map be adjusted as to compression by nut 21. he piston 19 has on its up er side a collar 22 fast with stem 23. ccordingly pressure air entering the cylinder 18 from the line 16 tends to push the piston 19 upwardly and compress the spring 20, thereby through the collar 22 lifting the stem 23 connected to rod 24 operating valve member 25 away from seat 26 in valve housing 27. This allows a gas sup ly from line 28 passing check valve 29 fi'om the main gas line 30 to flow through the line 31, valve 32 and line 33 into carburetor 34. The adjustment of the nut 21 may be such that the stem 23 may normally through the rod 24 hold the valve member 25 a sufficient distance from the seat 26 to allow of such flow of gas from the line 28 through the valve 27 and into line 31 to provide a pilot or heating gas supply in the carburetor chamber 34.
This carbureter chamber 34 has at its discharge end a nozzle 35 along the lowerside of this cylindrical carburetor chamber 34. This carburetor is disposed in the ash door opening 36 of a furnace 37, and in that po sition is preferably inserted in a duct 38 ex tending inward and upward to the region of the grate or fire box of the furnace where fuel therefrom may be dispersed in a grid 39 of fire brick, as a general heating region for the furnace (Fig. 7).
From the pressure air line 15, beyond the branch 16, extends pressure air line 40 to housing 41 which acts as a check valve, having therein a plunger 42 (Fig. 3) operable in a seat having fluted portions orgrooves 43 of one length altornating with shorter fluted portions 44 therebetween. The purpose of this fluting of various lengths about the plunger 42 is that there may not be chatter in the gradual unseating of the valve 42 from the action of pressure from the air line 40. This valve plunger 42 carries a stem 45 and is normally urged downward by a spring 46 acting from a guide piston 47, the position of which in the housing 41 is adjusted by a screw 48. This means of adjustment of the spring 46 and accordingly adjustment of the opening of this check valve 42 for allowing the pressure air from the line 40 to pass through this check valve 42 into line 49 en route to the furnace 37 by way of the ash door opening 36 and upward to coil portion 50 (Fig. 6) to be thoroughly heated, and as hot air, thence to pass by line 51 to adjacent the carbureter 34 where it may connect to the pressure oil line 52 and be delivered as a spray by nozzle 53 into the carbureter.
Accordingly the device of this disclosure is readily adaptable for quiet operation to either a gas supply or a liquid fuel supply and in either instance the hot air for the complete combustion is directly supplied to the carbureter 34. Preferably in Opelfitli'lll there is some gas supply maintained or at least sufficient to start the operation of the device but when once started it may he then continued by cutting the supply off by the valve 32 and opening the valve 12 control the amount of liquid fuel which it is uesired to have passed to the carbureter 34. The air pressure as controlled by the motor 3 from the thermostat will normally control the flow of gas if operating on gas by the 3; M tion of the valve member 25 in the hon: 27. If running on liquid fuel the or may be by the amount of pressure on tank 6.
Vhen the region to be heated has its temperature controlled by the thermostat and when the temperature for which apparatus is set is exceeded, the motor shut off. The shutting off of the mote; the burning of the fuel be gas, at once s of the gas by lowering the valve member 25 in housing 27. On account of the clearance for supplying the pilot in not fully clos ng the valve 27, there is still gas flow to lree the carbureter 34 heated.
If the operation be on liquid fuel from the reservoir 6, when the motor 3 is cut off the pressure on the line 5 at once drops and thus relieves the pressure in the chamber 6. The slight opening 10 in the line 9 precludes the siphoning of the fuel by line 11 so that at once there is a discontinuance of the flow of the liquid to the carbureter The advantage of the discharge openi the carbureter 34 is that in opei. on the A may be no condensation or collection. liquid in this carbureter the heated an: supply under pressure from small jet 53 e5 polling everything from this heat inst ed jacketed carbureter making it self-ole .ng at all times, There is some clearance about the eye of the duct 38 adjacent to the discharge opening 35 so there is a supple- 1,ees,ses
mcntary air supply in addition to the heated air supply from the coil 50.
