I, MOSES DAVIS of 44 Upper East Smithfield Merchant and Manufacturer do hereby
declare the nature of the said invention for "IMPROVEMENTS IN EXTINGUISHING DEVICES
FOR ROUND WICK LAMPS BURNING PETROLEUM AND SIMILAR OILS" (a communication to
me from abroad by the firm of Eckel & Glinicke of 52 Wasserthor Strasse, Berlin
German Empire, Lamp Manufacturers) to be as follows
This improved extinguishing device is applicable to lamps with round wick tubes
and a button or flame spreader. A sleeve or tube is made to surround the wick tube
and the sleeve is so connected with a lever that it may be raised or lowered by said lever.
The lever is pivotted at a convenient point on the body of the burner.
When the free end of the lever which extends outward is depressed the sleeve
surrounding the wick tube rises and approaching the underside of the button cuts off
the air supply so that the flame is extinguished.

Improvements in Extinguishing Devices for Round-wick Lamps
Burning Petroleum and similar Oils.
I, MOSES DAVIS of 44 Upper East Smithfield Merchant and Manufacturer, do
hereby declare the nature of the said invention for "IMPROVEMENTS IN EXTINGUISHING
DEVICES FOR ROUND-WICK LAMPS BURNING PETROLEUM AND SIMILAR OILS (a communica-
tion to me from abroad by the firm of Eckel & Glinicke of 52 Wasserthor-Strasse Berlin,
German Empire, Lamp Manufacturers) and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following statement:―
This improved extinguishing device is applicable to lamps with round wick tubes
and a button or flame spreader. A sleeve or tube is made to surround the wick tube and
the sleeve is so connected with a lever that it may be raised or lowered by said lever.
The lever is pivotted at a convenient point on the body of the burner.
When the free end of the lever which extends outward is depressed the sleeve
surrounding the wick tube rises and approaching the underside of the button cuts off
the air supply so that the flame is extinguished.
The construction may be varied one suitable form being shown in the accompanying
drawings in which is shown a sectional elevation of a lamp embodying this invention.
A is the wick-tube B is the body of the burner, C is the sliding tube D is the flame
spreader. E is the lever operating the sliding tube with which it is connected at each
side.
The lever Eis pivotted upon the body B at the point e and at E' is forked so as to
embrace the wick tube. At F the forked part of the lever is slotted so as to allow
pin to move freely in the slot.
The full lines show the position of the parts when the lamp is burning. When the
lever E is depressed so that it and the parts connected therewith assume the position
shown in the dotted lines, the edge e of the sliding tube is caused to bear under or
against the flange or rim d of the button D so that the wick being enclosed by an
airtight, or nearly airtight casing the flame is extinguished.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent, I declare that I claim -
In a round-wick lamp for burning petroleum and similar oils an extinguishing
device consisting in a sliding tube e operating in conjunction with flame spreader D
and actuated by a lever E or equivalent mechanism substantially as set forth and
illustrated in the drawings.
