Specification Accepted, 14th Dec., 1888
I, WILLIAM MOORE, of 143, Kingsland Road, in the County of Middlesex,
Engineer and Machine Tool Maker 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 :-
My invention relates to automatic extinguishers for lamps and has for its chief
object to provide an improved extinguisher which is applicable to lamps of a cheap
quality.
In the accompanying drawing
Figure 1 is a sectional elevation of a lamp burner provided with an extinguisher
constructed according to my invention, the said extinguisher being shown in the
position which it occupies during the time that the lamp is alight and
Figure 2 is a similar view to figure 1 showing the position of the extinguisher
after it has operated to extinguish the light.
Figure 3 is a plan of the burner as shown in figure 1.
Figure 4 is a side elevation of the extinguisher detached.
Figure 5 is an end elevation of the same, and
Figure 6 is a plan.
a is the body of the burner; 6 is the chimney gallery; c is the dome, and d is the
wick tube, all of which are of ordinary construction.
The extinguisher proper comprises a piece of metal cut and formed substantially as
shown in figures 4, 5, and 6, that is to say, with a horizontal strip e serving as a
cover to close the mouth of the wick tube, two end pieces or cheeks f, f and an
extension g which acts as a weight.
The extinguisher proper is pivotted through its end pieces or cheeks f, f to a pin h
fixed by means of solder or otherwise to one side of a tube a' adapted to be fitted on
the wick tube d of the burner, and so long as the wick i of the lamp is turned down,
the horizontal strip e lies immediately over the top of the wick tube d as shown in
tionre 2

page_text: When the wick is raised to light the lamp in the usual manner, it presses against
the underside of the strip e and causes the extinguisher to move aside on its pivot h
thereby allowing the wick to pass, as shown in figures 1 and 3.
On the wick being turned down within the wick tube, the extinguisher is caused
by its weight g to move back on its pivot and cover the top of the wick tube, thus
immediately extinguishing the light and obviating the danger resulting from the
practice of blowing the light with the breath to completely extinguish it.
From the above description it will be seen that the extinguisher is very inexpensive
to produce, can be easily applied to a lamp burner, and is therefore especially applicable
to lamps of a cheap quality.
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 extinguisher for lamps comprising a weighted cover adapted to
close the mouth of the wick tube, the said cover being pivotted to a tube adapted to
fit into the said wick tube, substantially as described.
(2.) A lamp having the improved automatic extinguisher hereinbefore described
with reference to the accompanying drawing applied thereto.
Dated the 9th day of November 1888.
