PILOT-LIGHT FOB GAS-BURNERS.
' Lights for Gas-Burners, of which the following is aspecifi'eation.
This invention relates to pilot lights; that is to. lights used with a bypass for lighting the main-jet of gas burners, and especially to pilot lights in which a coned shield is employed in connection therewith.
A pilot light made in accordance with this invention comprises a jet or burner surrounded by a'truncated coned shield so d is posed that the flame-passes through the orifice at the apex, the cone being closed at the base and provided with holes near the base.
Figure 1 is a cross section of one form of shield made in accordance with this inven- I tion.
Fig. 2 is a plan.
Fig. '3 is a cross section showing a modified construction. The shield a is a hollow truncated cone closed at the base with holes 6 b disposed near the base of the shield to supply air to the small flame d.- The pipe 0 carries the gas to the flame and is shown passing through the center of the base of the cone or shield. a
In the form shown in Fig. 3 the holes I) point toward the base for the purpose of preventing the air flowing directly into the flame.
In use, when the pilot light is burning, the
shield becomes hot and the air which supports combustion is warmed in passing through the small holes near the base of the shield and by the surrounding cone, the am is directed into the flame, which issues from the truncated end of theconical shield. The
' ing a long and pure flame.
flame preferably normally projects from the smaller end of the shield and toward the apex of point of convergence, rendering the combustion of the gas complete and produc- With a pilot light made in accordance with this invention,
.the flame will not be extinguished even in a violent draft of air, or byvexplosion or suction.,

blue flame which issues from the small open end of the incasing portion of the device a and is practically inextinguishable. flame, however, is not truly a Bunsen flame The I since the air entering the air ports 6 mingles with thegas issuing from the pipe 0 at the point of; combustion. In operation the air is drawn into the incasing through the air holes by means of the heat produced. The
holes in some instances are directed downwardly and have a tendency to give adownward direction to the air, whichair upon bea coming warm rushes with great force toward to thechamber space within the incasing and the opening at the small end through which the flame passes, are to be properly proportioned relatively to the amount and quality of gas intended to be used so that suflicient air will be supplied to maintain perfect combustion and the flame will be so proportioned to the opening through whichit passes that air will not find an entrance at that point.
What I claim is 2-- In a pilot light for gas burners, the combination with a shield in the form of a truncated cone having an open top and a closed bottom disposed in the plane of the base of rected towardthe bottom, and a gas burner within said shield having its gas outlet between the said open top and air openings and the cone, the sides of the shield being provided near .the bottom with air openings diso located that the flame thereof may pass out 'throughthe said open top.
In witness whereof I have hereunto signed my name in the presence of a subscribing witness.
