SAFETY FEED FOR OIL BURNERS.
Application filed .Tune 5,
To all 'zc/0m t may concern:
Be it known that I, lrLrnno FnANcis llamaron, a subject of the King of Great Britain, and a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Safety Feeds for Oil Burners, of which the following is a specification.
lilly invention relates to improvements in safety feeds for oil burners, and the object of my invention is to provide a simple, practical, and cflicient means whereby the oil feed is controlled solely by the heat created by the burner with which it is connected, or other heat creating means, consequent upon which the flow of oil to the burner is automatically prevented when the flame becomes extil ished from any cause Whatever, thus enabling such. burners to be used with great safety and adding greatly to their convenience and utility.
@il burners generally have the disadvan- 'age that in the event of the flame becoming extinguished the oil continues to flow to the burner unless it is stopped by some mechanical ccntrivance provided for the purpose and this, of course, is liable to get out of order and become useless and ineffective. Thus, in oil burners where such a means as is indicated in the preceding paragraph is not associated or embodied or in those provided with mechanical contrivances as above referred to the possibility exists of the flame becoming inadvertently extinguished, such as by being blown out by a gust of Wind, and if this is not noticed the oil continues to A[low and spread with the resultant danger of serious lire through ignition of the unnoticed overflow when reigniting the burner. This defect is entirely eliminated according to the present invention, a clear understanding of which will be had on referring to the accompanying drawing in which the ligure illustrates one form, more or less diagrammatically, in which the invention may be carried out.
l indicates generally a tube of substantially elongated U-form one leg 2 of which is open while the other leg 3 is closed at its upper end, being provided, however, at any suitable point adjacent its extremity with an orifice 4 forming a feed outlet between which and the burner (not shown), Whether retort, generator, vaporizer, Wick pan, or other analogous device, oil feed communi? 1924:. Serial No. 717,991.
cation may be established. The upper end of the leg 3 is preferably of reduced area, as shown, and indicated by the numeral l1. The orifice a may also be in the end closure 5.
6 indicates an oil supply tank from which extends a valved pipe 7 the end of which is disposed above the open end of the leg 2 of tube l while 8 indicates an overflow tank connected by a pipe 9 to an orifice l0 in the leg 2 positioned intermediate its length and slightly above the normal level of the oil in thetube l.
In operation oil is carried in the tube l with the levels in the respective legs 2 and 3 maintained under static head intermediate the length of the legs, the body of oil in the tube being` kept up by regulated feed from the supply tanlr 6 through the valved pipe 7. The oil vin leg 3 being within the Zone of heat, indicated by the dott-ed line and numeral l2, created by the burner, shown conventionally and indicated by the numeral 13, the volume of the oil in leg 8 is increased by the heat tending to vaporize the lighter fractions therein, thereby greatly expanding the total volume in leg 3 so that the level of the oil in leg 3 rises during operation of the burner and the oil flows through the orifice ei to the burner 13. Should, however, the flame be extinguished the heat zone no longer exists and consequently the oil in 3 returns to its normal level so that no oil can flow out through the orifice il, while at the same time the rise in the level of the oil in leg` 2 due to the continuous feed from pipe 7 is restricted to the height on the leg of the orifice 10 through which the accumulating oil in leg 2 overflows into the tank 8.
It should be here mentioned that the heat to which the column of oil in leg 3 is subjected, which is herein referred to as that existing within the burner heat Zone, may be heat created by any suitable means other than the burner; in other words, the heat zone may be created by any suitable heat conductor applicable to the purpose.
From the foregoing it will be seen that I have devised a safety feed for oil burners which is simple, practical, and efficient and entirely eliminates danger through overflow of the oil from the burner should it become inadvertently extinguished.
What I claim as my invention is:
g1. The combination with an oil burner, 0f
a feed pipe having its delivery end terminating in a straight vertical portion eX- terior of the burner proper closed at its upper end and provided with an orifice adjacent the closed end, said pipe being,` adapted to contain oil a portion of which extends as a vertical column into said delivery end the head `of the column being normally below and spaced from the said orifice and forming with the walls and closed lend of thevsaid delivery end a chamber exterior of the burner wherein the column expands undera heat Zone iniiuence to spill over at the orifice into the burner proper.
2. The combination vwith ,an oil burner, of afeed pipe havingits delivery end terminating' in -a straight vertical portion ei;- terior of the burner proper closed at its upper end and provided withian orilice adjacent lthe `closed end, said pipe being adapted to receive a regulated flow of oil Ya portion of which extends as a Vvertical column into said delivery end the'head of ythe column when cold being normally 1eelow and spaced a predetermined distance -from the oriiice and forming with the walls and closed end of the said delivery end a chamber `exterior 'of the burner wherein the column expands under a heat Zone influence to spill over at the orilice into the burner proper, anc means for maintaining the head oi'. the column when cold at the predetermined distance from the orifice irrespective of Ythe'continuity of the regulated oil iiow.
3. rihe combination with an oil burner, of a feed pipe having` its delivery end closed and provided with an oriiice adjacent the closed end and associated with the burner proper exterioiy thereof, said pipe being adapted to contain oil a portion of which extends as a vertical column into said delivery end the head of the column when cold 'being 'normally below 'and spaced a j ,deterinineddistance 'from the oriiicevand iorming lwith the walls and closed end of Jhe said delivery end a chamber wherein the column expands under a heat zone ini'luence to spill over at the orifice into Ythe -burner proper, means for feeding` a regu- Luence to spill over at the orice into the lated supply of oil lto said pipe, and anof a feed pipe arranged in substantially elongated ,lishape one leg being closed at its end and the other leg,` being open, the said yclosed end being connected to the burner exterioriy thereoi within the burner heat Zone and provided with an orifice adjacent the end closure, said pipe being rlapted to contain a body of oil a portion oiE which entends as a vertical column within each leg,v respectively, the head of the column in the closed leg` being when-cold normally/'below and spaced a predetermined distance yfrom the oriiice and forming with the Walls and closed end of the said delivery end a chamber wherein 'the column expands under the heat one influence to spill over at the orii'ice into the burner means for eediA a regulated supply of oil into the open to maintain the` oil body constant, and an overiiow tanlr associate-d Ywith said open l Y having a connection eX- tending therebetween connecter to the said open leg at a point intermediate its mouth and the head of 'the oil column therein, said tanlr 'being below the point o connection.
5. rlhe combination with an oil burner, of a feed pipe arranged in substantiallv elongated e5-shape one leg being closed at its end and the other being open, the said closed end being disposed exterior of the burner `within vthe burner heat zone and provided with an oriiice adjacent the end closure, said pipe being` adapted to contain :oil a portion of which extends as a vertical column withinl each leg` respectively, the head oic the column in the closed being when cold normally belov.T and space-il from the orifice and orr g with the LWalls and closed end of the saidv deliveryT end a rchamber exterior of the burner .vherein the column expands under the heat :zone inburner proper.
