We, BENJAMIN HISCOCKS, of 43, The Avenue, Pontypridd, Commission Agent,
and JAMES LOCK, of Danygraig House, Williamstown, Rhondda Valley, Glamor-
ganshire, Grocer, do hereby declare the nature of this invention to be as follows:-
A cap fixed to burner on a hinge, at each end a lever from which hang two
chains with weights attached, one heavier than the other, the heaviest resting
on a little platform on the outside of lamp; on the lamp being tilted over in any
way, weight is tilted off platform and draws cap down over wick extinguishing
light. Appliance can be fixed to any lamp.

Improvements in Extinguishers for Oil and like Lamps.
We, BENJAMIN HISCOCKS, of 43, The Avenue, Pontypridd, Commission Agent,
and JAMES LOCK, of Danygraig House, Williamstown, Rhondda Valley, Glamor-
ganshire, Grocer, 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:-
This invention relates to means for extinguishing oil and like lamps. It con-
sists in an extinguishing device whereby, in event of the lamp to which it is
fitted being upset, an extinguishing cap is drawn down on the wick top and
thus the flame becomes extinguished.
The extinguishing cap is hinged to the burner or to a casing surrounding the
burner, and the hinge pin is connected at each end to chains which are attached
to counterweights. The counterweight attached to one end of the hinge pin is
heavier than that connected to the other. When the heavier counterweight is
not acting on the extinguishing cap, the said cap is kept tilted back by the
lighter counterweight which is adapted and connected to fulfil that requirement.
The heavier counterweight, when not in action, rests on a platform or against a
beading or moulding in such manner that it exerts no strain on the extinguishing
cap. In event of the lamp being upset, or sufficiently tilted, the heavier counter-
weight is dislodged from its resting place and, overcoming the resistance of
the cap and the other counterweight, draws the cap on to the wick top and so
causes the flame to be extinguished.
Referring to the accompanying sheet of drawings, Fig. 1 represents a sectional

page_text: view of so much of an oil lamp as serves to illustrate the extinguishing device
in which this invention consists. The usual burner dome is omitted from the
drawing for simplification. Fig. 2 is a side view as seen from that side of the
lamp at which the heavier counterweight is situated. Fig. 3 is a view of the
opposite side, that at which the lighter counterweight is arranged. In all
the views the extinguishing cap is shown as raised.
The extinguishing cap a is hinged by the pin 6 to the casing c surrounding
the burner d. The cap a might be hinged directly to the burner. At the side
at which the heavier counterweight e is situated, the hinge pin b is turned to form
an arm b¹ which is fixed on the top of the cap. To the arm b¹ is attached one end
of a chain which, at the other, is attached to the counterweight e. At that
side of the lamp at which the lighter weightg is situated, the hinge pin 6 is bent
to form a loop 63 to which is attached one end of a chain h, the other end of which
is attached to the weight g.
In the lamp shewn in the drawings the chains f and h are guided to the
respective weights e and g by tubes i and ; provided in the lamp cone k. But
the chains can be otherwise guided, and in some lamps such guide tubes are not
required.
The heavier weight e is shewn in the drawings as resting on the lamp body
and against an annular beading 1. The weight e while in this position does not
exert a pull on the cap a, which is held in the raised position by the weight g.
In event of the lamp being upset, the weight e is dislodged and the cap a is pulled
down on the wick, and the flame becomes extinguished. In lamps not having a
beading similar to the beading 1, a shelf or other place is provided for the
weight e to be deposited on for its state of rest. The place provided must
obviously be such that the weight is free to fall from it when the lamp is
sufficiently tilted.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is:-
An extinguishing device for extinguishing oil and like lamps; consisting of
an extinguishing cap hinged to or near the burner and having its opposite ends
connected by chains or the like to counterweights of different weight, the lighter
of which keeps the extinguishing cap raised when the heavier is out of action.
and the heavier of which causes the extinguishing cap to be drawn down and
the flame to be extinguished when, by the tilting of the lamp, the said heavier
weight is dislodged from a place of rest. and inaction, provided on the lamp,
substantially as hereinabove described with reference to the accompanying draw-
ings.
