page_text: WALTER GEORGE CLOKE 90 Bellenden Road Peckham Cattle Dealer do hereby
declare the nature of this invention to be as follows:-
The invention consist of an improved burner and extinguisher combined it may
either be placed over the burner of an ordinary lamp or used in the place of an
ordinary burner it consists of two sides or checks of the burner being movable (on
springs hinges or both) clasping the cotton when up and alight, and closing together
after it when drawn down by the handle of the lamp at the same time extinguishing
the light by its passing between the sides or cheeks of burner as it is drawn down by
doing so it does away with the dangerous practice of blowing lamps out with the
mouth which very often tends to setting the oil alight and causing explosions.
Dated this 13th day of January 1887.

page_text: I WALTER GEORGE CLOKE of 90 Bellenden Road, Peckham, Surrey, Cattle Dealer
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:-
(1 propose to abandon all claim to the improvement in the burner and to restrict 5
my invention to the mode of constructing and applying an extinguisher for oil
lamps.)
According to this invention automatically acting extinguishers for lamps can either
be made so that they can be sold separately from the lamp and be easily applied to,
or detached from, the burner, or as part of the wick tube of the burner.
To enable my invention to be properly understood I will proceed to describe the
same with aid of the accompanying drawings.
Figure 1, perspective view of extinguisher detached from burner.
Figure 2 end view of same applied to wick tube of burner.
Figure 3 similar view with auxiliary spring.
Figure 4 perspective view of a modification of figure 1 showing wick ready for
lighting.
Figure 5 perspective view showing extinguishing device closed.
Figure 6 front view of figures 4 and 5.
Figures 7 and 8, sectional end views of figure 6 showing extinguishing device 2
open and closed respectively.
A, A, extinguishing flaps, B, wick tube of burner, C, wick. In figures 1. 2 and 3
the flaps are held closed by spring appliance sufficiently weak to admit of their being
pushed apart by the wick when it is turned up. On turning down the wick the
spring causes the flaps to close over it, and so extinguish the light.
The spring
appliance may either consist in making the bottom extremity of Hap A', small and
thin to act both as spring and hinge for the flap, or of an auxiliary spring as shown at D,
figuro 3; or both the spring extremity A' and spring D, may be used together. The
flaps are stamped out in one piece with a band F, this is turned round and connected
to form the band F, into a collar to fit tightly round the wick-tube to retain
extinguisher in working position. This means of attaching an automatically acting
extinguisher to the wick-tube of a burner admits of the extinguisher being readily
put on or taken off.
A modification of the above arrangement is to hinge the flaps A, A, to the wick
tube in such a way that when the extinguisher is open, they form part of the wick-tube;
illustrated at figures 4, 5, 6, 7, 8. In this arrangement no spring is necessary to actuate
the flaps which fall inwardly on the wick-tube being turned down, but if desired a
1

page_text: spring could be applied. A band E, is attached round the top of wick-tube to prevent
the flaps falling outwardly and hold them properly vertical to form part of wick-tube,
and also to support the projecting ends on top of wick-tube. Or in place of two flaps,
one flap could be used.
Having now particularly described and ascertained the nature of my Invention and
in what manner the same is to be performed, I declare that I claim is
1. An automatically acting extinguisher attached to the wick-tube of a burner by a
tight fitting collar to which the extinguishing part is connected substantially as
hereinbefore described.
2. An automatically acting extinguisher in which the extinguishing part when open
forms a portion of the wick-tube, substantially as described.
