This Invention relates to an improved method of Extinguishing Oil Lamps, and it
consists essentially in Employing the wick itself to operate the Extinguisher. The

page_text: application of my method is illustrated on the Sheet of Drawing loft with my
Provisional Specification, upon which :-
.
Figure 1. Represents a burner having an Extinguisher according to my invention,
the Extinguisher being over the top of the wick Tube and the lamp Extinguished;
and Figure 2 shows the wick tube detached, the Extinguisher thrown back by the
raising of the wick, and the Lamp burning.
It will be seen that each end of the wick-tube is provided with a small pin or stud A
forming pivot for the metal shutter or plate B (hereinafter termed the Extinguisher)
which has an indented edge and is provided with a projection C as shown.
Assuming the extinguisher to be in the position shown Fig. 1 by winding up the
lamp wick, using the ordinary wick winder D, the Extinguisher B is pushed by the
rising wick over to the position shown Fig. 2, at which point it is arrested by
the projection G.
By reversing the motion of the winder D, the wick is lowered and directly its top
comes below the indented edge of the Extinguisher B this latter by its own weight
pivots over on to the wick tube as a Fig. 1 and Extinguishes the flame.
I may make the Extinguisher of any suitable metal or material and attach or hinge
it on to the wick tube in any convenient manner, provided always that when pushed
back to its fullest extent by the rising of the wick it still rests against it and must fall
over it when drawn down by the winder.
I also prefer to indent or serrate the edge of the Extinguisher which lies against
the wick when this latter is raised to allow access of air to the flame.
Amongst the advantages of my improved method of Extinguishing the light in oil
Lamps are, that the Extinguisher is automatic, the ordinary lowering of the wick
causing it to fall by its own weight without the aid of any spring, and that being
fastened on the outside of the wick tube it can be affixed to any lamp burner without
any modification thereof.
Having now particularly described, and ascertained the nature of my said Invention,
and in what manner the same is to be performed I declare that what I claim is —
1. The improved method of Extinguishing the light in Oil Lamps by an Extin-
guisher operating automatically upon the lowering of the wick in the ordinary
manner, substantially as described.
2. In combination with the wick tube of an oil Lamp, the Extinguisher B arranged
to pivot on the wick tube thereof upon the raising or lowering of the wick by the
winder D, substantially as hereinbefore described and shown on the Drawings.
