Extinguishing II
or spirit
Lamps and for Preventing Explosions of the same.
I, HENRY DYER of Addington Square Camberwell in the county of Surrey Chemist
do hereby declare the nature of this invention to be as follows:-
--
The nature of my Invention consists in a novel method of attaching a Flat Spring
or Springs inside the Tube which carries the Wick from the reservoir to the
Burner.
A further part of my Invention is for the purpose of Extinguishing and preventing
explosion of the ordinary Oil or Spirit Lamps now in use.
The principle I adopt is to cause the Wick in the act of being lowered for the
purpose of extinguishing the lamp to come into contact with the said Spring or
Springs which immediately shuts off the flame and by preventing communication
from outside renders it impossible for any person to pass air through the Wick tube
by blowing down the chimney into the reservoir.

Lamps and for Preventing Explosions of the same.
1, HENRY DYER of Addington Square Camberwell in the County of Surrey Chemist
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:
In furnishing a full and complete description of the nature of my Invention and
the manner in which it is constructed and manufactured I claim entire novelty in
combination with simplicity durability and cheapness.
1 attach inside the Wick Tube and on the opposite side to the Cogged Wheel
Grippers of the ordinary Oil Lamp a Flat Spring A or in the case of a Duplex
Burner two Springs one inside each Wick Tube the said Spring to be made of rolled
Steel or other metal of a proper thickness and elasticity; the Spring to be of sufficient
width to pass inside the Wick Tube fitting easily with just sufficient margin to give it
play and its length when fixed to be one eighth of an inch less than that of the Wick
Tube measuring from the top of the Tube.
Having cut the spring A to the proper length I turn back the upper end or top B
about the sixteenth part of an inch to prevent any particles of burnt wick passing
down the tube and 1 then soften the lower portion (that is the part to be attached to
the bottom of the Wick Tube, by lapping over the side of tube at point marked *)
and then turning up the end on the same side as the upper end and secure it by means
of solder in its correct position on the opposite side of the grippers as shown at *
Fig. I. and Fig. II.
The Spring can also be fixed by one or more rivets and can be adapted to any
width of any Flat Wick Tube now in use whether for lighting heating or cooking
purposes.
I also, if necessary can lengthen the Wick Tube downwards into the reservoir.
When the Wick is being elevated or raised out of tube by the grippers for the
purpose of lighting it (D Fig. 2) the spring (A Fig. I) being of the requisite
elasticity, presses gently on the cotton wick thereby regulating the supply of oil and
preventing smoke, and when the Wick is lowered as in Fig. 1 the upper and
unattached portion of the spring closes over it as it passes down and immediately
extinguishes the flame.
If requisite I also widen the grippers or add more cogged wheels according to the
width of the Wick to be used.
This Invention is more particularly shown in the Drawings herewith as follows:-

tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. Novelty in combination with simplicity durability and cheapness.
2. To prevent explosions by the act of any person blowing down the chimney.
3. To regulate the supply of oil consumed thus preventing smoking.
4. Immediate extinction of flame by lowering the wick.
