page_text: 1, JOHN SANDERS, 3 St. John's Gardens, Queens Crescent, Haverstock Hill, N.W.,
General Tin Plate Worker, 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 :-
Reference being also had to the accompanying sheet of drawings illustrative of my
said Invention, in which Figure 1 represents an elevational view of the extinguishing
device adapted to an ordinary lamp burner, Figure 2 a plan-taken on the top of
same showing the device with the cone of the lamp burner removed, and Figure 3 a
detached side view of one of the extinguishers and working attachments connected
therewith.
My Invention consists of an appliance to be attached to an ordinary lamp burner
for extinguishing the light; and, the device being self acting the light or flame will
be extinguished should the lamp be accidently overturned.
It comprises two levers E, F, (weighted at B,) with cranked spindles H, I, and
extinguishers C, D, the latter being provided with hooks and weights attached to the
lower extremity of each. Two cross bars a are fastened at the top of the ordinary
wick tube A, and are pointed at each end, the points being turned inward as shown.
On each of these points of the cross bars a are suspended the extinguishers C and D,
which are made flat, and preferably wider at the top than bottom, with row of holes
across centre. Said extinguishers C and D are bent, and suspended in the centre by
their lateral extension pieces b, and are weighted at the bottom, thus retaining same in
an upright position when the lamp is burning; but when overturned on its
side, (as for instance on the line X Figure 1,) it will be evident that the top of the
whilst
wick tube A will press against the upper portion of the lower extinguisher D,
the lever E at the same time descends, moving the spindle H, which in turn causes the
crank I to press against the bottom of the extinguisher C, forcing the upper portion of
same over on the top of the extinguisher D, thereby completely covering the wick
tube A and extinguishing the light or flame of the burner, the hooked formation at
the lower portion of the extinguisher preventing the crank Í from passing the bottom
thereof; so that when the lamp is righted, and the wick tube A again upright, the

page_text: lever E resumes its normal position of rest, and the extinguishers C and D, being
weighted at their lower ends as before stated, are caused to open and uncover the wick
tube A.
The action of the levers and extinguishers is the same if the lamp is overturned on
either of its sides. Should the lamp be overturned endways, that is to say upside
down, the two levers E, F open, and the cranks I of the spindles H caused to press
against the bottom of the extinguishers C, D, thus forcing the upper portion thereof
over the top of the wick tube A and extinguishing the light or flame of the burner as
before stated.
It will also be obvious that in accordance with my Invention the usual method, of
extinguishing the light by blowing down the lamp chimney is entirely obviated, the
flame being readily extinguished by forcing the levers E, F, outwards, thereby
enabling the extinguishers C, D to cover the wick tube A as hereinbefore
described.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what I.
claim is :-
In appliances for extinguishing the light or flame of oil lamps, the combination of
the weighted extinguishers C, D, levers E, F, cranked spindles H, I, and attach-
ments a, b, substantially as herein described and shown in the accompanying
drawings.
