Circular Wicks.
I ALBERT GRAY of Greville Lodge, Amyand Park Road, Twickenham, Engineer,
do hereby declare the nature of my said invention to be as follows :-
This invention relates to a novel combination of appliances for use in a circular
wick oil lamp for extinguishing the flame either by an automatic action in the case of
an upset or fall over or the mechanism may be operated by hand.
The invention consists of a couple of tubes, one inside the wick and one outside the
wick said tubes being connected by a rod or bar riding in a slot of the wick carrier
and capable of being raised and lowered by rack and pinion from an outside turn
button, the rod or stem of which has a lever connected by a cord or chain having at
its opposite end a spherical or other shaped weight which can, by a jolt or concussion
be thrown out of a cup and cause a pull on the cord and lever, lift the extinguisher
tubes to put them into contact with the spreader button to shut off the flame or if no
spread button be on the lamp, the two tubes are raised to such a height that the flame
is extinguished.

Circular Wicks.
I, ALBERT GRAY, of Greville Lodge, Amyand Park Road, Twickenham, Engineer
do hereby declare the nature of this invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
This invention relates to a novel combination of appliances for use in a circular wick
oil lamp for extinguishing the flame either by an automatic action in the case of an
upset or fall over, or the mechanism may be operated by hand.
The invention is shown in the annexed drawings Figures 1 and 2 and consists of
a couple of tubes A, B, one inside the wick and one outside the wick, said tubes A, B,
being connected by a rod or bar C riding in a slot of the wick carrier and capable of
being raised and lowered by rack D and pinion E from an outside turn button if
desired. The rod or stem F of the wick lifter has a lever G attached and this lever is
connected by a cord or chain H to a spherical or other shaped weight I.
The cord or chain H passes through a hole J in the bracket K and the ball I which
temporarily rests in the cup L can, by a jolt or concussion be thrown out of a cup L
and cause a pull on the cord H and also on the lever G, whereby the extinguisher
tubes A, B, are put into contact with the spreader button M to shut off the flame,
but if no spreader be on the lamp, the two tubes are raised to such a height that the
flame is extinguished, the supply of air being prevented from gaining access to the
top of the wick and flame.
The rack is preferably secured to the outer extinguisher tube A at its upper end
only and the rack teeth are kept in contact with the pinion by a spring N secured to
the outer tube with its free end bearing against an inclined plate P the contact of the
spring against the plate P being sufficient to hold the extinguisher tubes at the
position at which they may be lifted.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
"
The two tubes A, B, connected and arranged as set forth and their operation by
rack and pinion as flame extinguisher tubes as shown in the annexed drawings.
