PROVISIONAL SPECIFICATION.
Improved Means for Extinguishing Oil Lamps.
I, JOHN DENNIS YOUNG, of Barnstaple, in the County of Devon, Metal Merchant,
To hereby declare the nature of my said invention to be as follows:-
My Invention consists of improvements in extinguisher mechanism which can be
operated by hand when required and that will also by self action extinguish the light
the lamp is tilted over or upset.
Description of the Drawings hereunto annexed.

Improved Means for Extinguishing Oil Lamps.
I, JOHN DENNIS YOUNG, of Barnstaple in the County of Devon, Motal Merchant,
do hereby declare the nature of this invention and in what manner the same is to he
performed, to ho particularly described and ascertained in and by the following
statement:
My Invention consists of improvements in extinguisher mechanism which can be
operated by hand when required and that will also by self action extinguish the light.
if the lamp falls vertically or is tilted over or upsets.
Description of the Drawings left with the Provisional Specification which are also
adopted for this Complete Specification.
Fig. 1. is a vertical view of the inside of the burner shewing the extinguishing
mechanism.
Fig. 2. is a plan of the same, the mouth cone and baffle plate being removed.
a, is the burner. b, is the mouth conu. c, is the baffle plate. d, is a weight of leadi
or other heavy materiel cast upon or fixed to the inner part of the lever E. There is a
central holo in this weight in order that in its movement it may always be clear of
the wick tube. This lever is hinge jointed to a bracket or piece G, fixed to the
burner; it extends outwards beyond the joint to form a bandle by which the
extinguisher may be operated by hund, when required, to extinguish the light. El, is
n trough shaped extinguisher bung upon the horns of a metal mount 1, fixed to the
wick tube. J, is an eye ended wire connecting rod, one end of which is jointed to a
pin in the lead weight and the other end to an eye in the back of the trough
extinguisher; a suitable hole is made in the baffle plate to allow of the connecting
rod working through clear of it. K, is a wire spring, one end L, of which is soldered
or otherwise fixed to the burner and the other or free end is made to press upwards
against the under edge of the lever E. M, collar to fix the wick tube central.
N, winder case.
The netion is as follows:-When the lamp is either suspended or supported upright
the free end of the spring will be depressed by the gravitation of the weight d, which
will descend in the burner sufficiently to pull back the extinguisher H, and fully
uncover the wick; (the Drawings shew the extinguishing mechanism in this condition)
but should the lamp at any time fall, or be inclined or tilted over, even less than
90 degrees from the perpendicular, the lover pressure upon the spring end would be
reduced and the power of the spring would then overcome the gravitating resistance
of the weight and thrust it towards the top of the burner and force the extinguisher
to cover the wick and extinguish the light. Hand pressure upon the lever E, outside
the joint will cause the light to be extinguished. The baffle plate, burnor and gallery
perforations are not shown in the Drawings, they are to be as commonly made.
Having now particularly described and ascertained the nature of my said Luven-
tion and in what manner the same is to be performed I declare that what 1
claim is
(1.) In oil lamps the automatic extinguishing apparatus consisting of a weighted
lever E, hinge jointed to the burner and actuated by the spring K, in combination
with flame extinguishing devices arranged and operating substantially as hereinbofore
described and illustrated by the Drawings left with the Provisional Specification.
(2.) The combination of the automatic extinguishing apparatus with the means for
extinguishing by hand, when desired, substantially as hereinbefore described and
illustrated by the Drawings loft with the Provisional Specification.
