PROVISIONAL SPECIFICATION.
An Improved Automatic Lamp Extinguisher.
We, JOHN THOMSON PAUL and JAMES PAUL, of Grove Works, Edinburgh,
in the County of Midlothian, Paraffin Lamp Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention has for its object to so construct the extinguisher that immediately
the lamp is on an incline as in the act of falling, the light is automatically
extinguished.
The invention consists in connecting to the extinguisher a leg which passes
through the bottom of the burner. This leg below the burner takes the form of
an or other suitable shape. Connected to the leg below the bottom of this
burner there is a chain or other device which passes through an eye fixed on the
underside of the burner. The other end of the chain is connected to a weight,
which in its normal position rests in the L-shaped piece of the leg.
The operation is as follows:-In the case of a lamp being knocked over,
immediately it is in the act of falling, the weight is displaced from the rest, which
pulling down the chain or other device, raises the leg having the extinguisher
attached to it, and so extinguishes the light.
It is to be understood that this arrangement can be applied to any ordinary
extinguisher.

COMPLETE SPECIFICATION.
An Improved Automatic Lamp Extinguisher.
We, JOHN THOMSON PAUL and JAMES PAUL, both of Grove Works, Brandfield
Street, Edinburgh, in the County of Midlothian, North Britain, Lamp Manu-
facturers, 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:-
Our invention has for its object to so construct the extinguisher that immediately
the lamp is on an incline as in the act of falling, the light is automatically
extinguished.
In order that our invention may be properly understood and readily carried into
effect we have hereunto appended an explanatory sheet of drawings which we will
now proceed to describe.
Figure 1 is a section of an ordinary lamp showing our improvements applied
thereto.
Figure 2 is also a section of a part of a lamp.
The invention consists in connecting to the extinguisher A a leg B which passes
through the bottom of the burner C into the reservoir I of the lamp. This leg B
below the burner takes the form of an L or other suitable shape. Connected to the
leg B below the bottom of this burner there is a chain D or other device, which
The other end of
passes through an eye E fixed on the underside of the burner.
the chain is connected to a weight F which in its normal position rests on
the L-shaped piece of the leg in the reservoir I as shown on the drawings.
The operation is as follows:-In the case of the lamp being knocked over,
.

page_text: immediately it is in the act of falling, the weight F is displaced from the L-shaped
piece of the leg B, which pulling down the chain D, or other device, raises the
leg B having the extinguisher A attached to it, and so extinguishes the light. The
weight is raised again into its position by means of the lever G..
It is to be understood that this arrangement can be applied to any ordinary
extinguisher.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In oil reservoirs, the arrangement for automatically extinguishing the light in
the event of the lamp being tilted over, substantially as described and shown.
2. The leg connected to the extinguisher and passing through the bottom of the
burner, substantially as and for the purposes hereinbefore described and shown on
the drawings.
3. The chain connected to the leg and passing through an eye and having a
weight attached to the end of it, substantially as and for the purposes hereinbefore
described and shown on the drawings.
Dated this 29th day of September 1892.
