useful Improvements in a Pilot Burner, of'
j which the following is a specification.
My invention relates to oil and gas` burners and particularly to' devices of the sort with which arpilot light or burner is employed to effect resigntion in event of extinguishment.
In the devices such as describedv with which fuel oil isemploved, it is customary to provide a pilot light 'in which gas is used, the ordinary method involving the.
maintenance of a small gas flame. or jet. Such a burner is wasteful in its consumption of gas and is very easilyextinguished. If it is extinguished .the fuel oil'is likely to be discharged into the heaterV without beingA stem 19 projects downwardly from the valve [member and into a small diaphragm 20 Vwhchserves to seal the valve and avoids the necessity Yof packing the stem 19. A
motor diaphragm Yor .disk 21 abuts thesealing .diaphragm 20, 'the' parts being held ignited. l
In the device of my inventionI accomplish two objects,first,.the provision of a burner which is not readily extin ished and which will VVbe instantly re-ignlted il' effect of such an occurrence and second, the provision of a thermostatic control asso'- ciated with the pilot burnerandactingv to interrupt the supply 'of fuel to the main burner in the event of the necessity therefor.
The pilot burner of myinvention is referably of the Bunsen type, which proVV ucesa hotter iame with a reduced 'quantity of gas. This typev of burner also eliminates the production of soot. To effect resignition in the event of the accidental extinguishing of the pilot, I provide at a point adjacent to the outlet'from the pilot burner, are?" fractory element adapted "to be maintained in an incandescent or red hot, state. Inasmuch as the pilot burner is usually ex-I tinguished by reason of an explosive -pu' in the rebox the burner will be immediately re-ignited due to the contact -of the gasV with the incandescent re-ignition point.
The thermostatic element is preferably in the form of a tube clamped to the pilot burner and communicating -by a flexible tube with a motor diaphragm which oper-v ates a fuel shutoff valve which is normally closed except when held open by the thermostatic pressure. A li uid having a low boiling point is confined 1n the thermostatic tube and will serve to maintain the valvie in open position when the burner is in operspringland the interruption of thev guished the lreducedx-thermostat'c Vpressure will permit theclosing of the valve bythe .Suppl of fuel tothe main burner.
My invention will be more readilyfunderstood byreference to the accompanying drawing, in which- V The; figure is an elevation partly: insection showing an arrangement such as .conceivedlby me.
In the drawing, the device is shown projecting through arwall 10 of a furnace or a heater, a fueloilburner 11 serving to .provide the heating flame. Fuel is supplied to the burner by means of the by means ofthe pipe 13.
14 lis provided `in .the oil supply line, this including a valve member 15 .normally held a ainst 'its seat by means of a sprin 17 hel in position by a closing cap 18.
within a yoke 22 secured to the valve` fitting 14. An armored tube connects 4the interior 'of the motor diaphragm 21 with a'rigid tube24-which acts as a thermostat-ic bulb and is lheld by means of clamp 25A against the pilot burner 26 which also projects into the furnace beneath the main burner. The
-pilot burner 'is preferably of the Bunsen -type and is provided -with a transverse l' venable itto withstand the heat and be maintained at incandescence or. at least at such temperature aswill effect re-ignition of the gas in event of a puff in the furnacewhich. would serve to extinguish-thepilot burner.
PATENT- OFFICE.;
' ation." Reverselyl when' the pilot is ex-tin# Ripe .12 and air' shutoff -valve loo,
The arrangement is such that in event l of the extinguishment of the pilot burner, the temperature-thereof-will be reduced and the thermostatic'li uid within-the bulb will be condense thusv permitting the spring 17 to close the fuel valve 15. This.
will serve to prevent the escape of unburned fuel into the heater. i
