PROVISIONAL SPECIFICATION.
Improvements in Extinguishing Mechanism for Oil Lamps.
I
"I, JOSIAH SMITH, of 109 to 111 Duke Street, in the City of Birmingham,
Wood Turner, do hereby declare the nature of this my said invention to be as
follows:-
This invention relates to improvements in extinguishing mechanism for oil lamps
and its object is to so construct and arrange the burner and its adjacent parts as
that when by accident or from other cause the said lamp shall be upset or thrown
over or hurled forward the light shall be immediately automatically extinguished.
By the same construction and arrangement the lamp may be extinguished at any
time at will. Its construction is somewhat as follows: but the parts herein described
may be altered in detail to some extent without departure from the nature of the
invention.
The burner (speaking as a whole) is made in two parts, that is broadly the
winding mechanism and the wick tube or tubes and a well or open top chamber,
and the extinguishing shutters or flaps comprise broadly the one part which I will
term the lower part, while the cone, the chimney holder and gallery and means for
operating the extinguishing flaps or shutters comprise the other part, which I will
term the gallery part. This gallery part has a circular base plate or flang which
is capable of entering and lying within the aforesaid well of the lower part. 'Upon
the interior of the cones are projecting arms which impinge upon and actuate the
extinguishing shutters when extinguishment is effected.
Referring to the lower part:-At or near the bottom of the inside of the burner,
and usually at the sides of wick tubes are provided hinge joints upon which are
carried extinguisher flaps or shutters whose upper ends may be closed together so
as to completely cover the wick. In their normal condition these two flaps lie open
wide apart their exterior surfaces resting upon the projecting arms attached to the
interior of the cone.
The well of the lower part is horizontally disposed and adapted to receive
and accommodate the base of the gallery part before described, the said well
being formed or carried upon the perforated bottom part of the burner and above
the winding mechanism. To ensure the flame slot or slots in the cone agreeing as
to position with the wick I provide one or more pegs in the bottom of the gallery
base which shall-when in correct position-engage with holes in the base of the
well.
This well is deep enough to permit a considerable amount of movement therein
of the gallery part, and the metal of the upper edge of this said well is turned over
so as to form a narrow flange inwards, to prevent the base plate of the gallery part
from detaching itself entirely from the lower part, but a slit is provided in the
said turned over edge by which the gallery part may be inserted or removed when
desired.
The gallery part is so weighted and its base is of a sufficient size to effectively
keep the same upright when the lamp is perpendicular, but immediately the lamp
is overturned the centre of gravity of the gallery is changed which causes the same
to tumble over, and in so doing the projecting arms with the cone in their forward
movement immediately close the shutters and thus extinguishes the light. In

page_text: order to extinguish by hand it is merely necessary to vertically lift the gallery
part by which the shutters are closed as before.. This my invention is applicable
to single or double wick burners, circular wick burners, or other wick tubes where
similar shutters may be used and similarly operated.

I, JOSIAH SMITH, of 109 to 111 Duke Street, in the City of Birmingham,
Wood Turner, 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 improvements in extinguishing mechanism for oil lamps
and its cbject is to construct and arrange the burner and its adjacent parts so that
when by accident or from other cause the said lamp shall be upset or thrown
forward the flame shall be automatically extinguished. By the same construction
and arrangement the lamp may be extinguished at any time at will.
I effect these improvements by the mechanism illustrated upon the accompanying
drawings and herein referred to.
Fig. 1, is a central sectional view of the upper part of the burner of the
lamp.
Fig. 2, is a section plan view of the upper part of the burner on line A-B.
Fig. 3, is a view in side elevation of the lower part of the burner having a
portion of its outer well removed in order to show the shutter mechanism.
Fig. 4, is a plan view of the aforesaid lower part of the burner.
Fig. 5, is a sectional view in elevation showing the upper and lower parts of the
burner in their ordinary position for use.
Fig. 6, shows the position the two parts would assume when the lamp was
upset.
Its construction is somewhat as follows; but the parts herein described may
be altered in detail to some extent without departure from the nature of the
invention.
The burner (speaking as a whole) is made in two parts 7 and 8, that is, broadly,
the winding mechanism 9 and the wick tube 10, and a well or open top chamber 11,
and the extinguishing shutters or flaps 12, 12, comprise broadly the one part,
which I will term the lower part, while the cone 13, the chimney holder 14 and
gallery 15 (shown in dotted lines see Fig. 5) and the projecting arms 16, 16, for
operating the extinguishing flaps or shutters comprise the other part, which I will
term the gallery part. This gallery part has a circular base plate or flange 17
which is capable of entering and lying within the aforesaid well 11 of the lower
part 7. Upon the interior of the cone are the projecting arms 16, 16, which
impinge upon and actuate the extinguishing shutters 12, 12, when extinguishment
is effected. Referring to the lower part of the burner:-At or near the bottom of
the inside of the burner, and usually at the sides of the wick tube are provided
hinge joints 18, 18, upon which are carried the extinguisher flaps or shutters 12, 12
whose upper ends may be closed together so as to completely cover the wick
tube as seen in Fig. 6. In their normal condition as seen in Fig. 5, these two
flaps lie open wide apart their exterior surfaces resting upon the projecting
arms 16, 16.

page_text: The well of the lower part is adapted to receive and accommodate the base 17
of the gallery part. To ensure the flame slot 19 in the cone agreeing as to
position with the wick tube 10, I provide one or more pegs 20, in the bottom of the
gallery base which shall-when in correct position-engage with holes 21 in the
base of the well.
This well is deep enough to permit a considerable amount of movement thereio
of the gallery part, and the metal of the upper edge is turned over at 22 so as to
form a narrow flange inwards, to prevent the base plate 17 of the gallery part,
from detaching itself entirely from the lower part, but a slit 23 is provided in the
said turned over edge 22 by which the gallery part may be inserted or removed
when desired.
The gallery part is so weighted and its base is of a sufficient size to effectively
maintain the upright position when the lamp is perpendicular, but immediately the
lamp is overturned the centre of gravity of the gallery is changed, which causes
the same to tumble over as seen in Fig. 6, and in so doing the projecting arms 16, 16
in their forward movement with the cone, immediately close the shutters and thus
extinguishes the flame. In order to extinguish by hand it is merely necessary to
vertically lift the gallery part 8 by which the shutters are closed as before. This
my invention is applicable to lamp burners having single or double wicks where
similar sbutters may be used and similarly operated.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In oil lamp burners the combination with the movable upper part 8 having
the flange 17, of the well part 11 having extinguishing mechanism and carried upon
the lower part 7, all substantially as set forth and shown, and for the purposes
specified.
2. In oil lamp burners the combination of the lower part 7 having the
shutters 12, 12, and wick tube 10, with the movable upper part 8 having the
projecting arms 16, all substantially as set forth and showo and for the purposes
specified.
3. In oil lamp burners the combination with the lower part 7, having the
shutters 12, 12, wick tube 10, well 11, and holes 21, 21, of the upper movable
part 8, having the arms 16, 16, cone 13, holder 14, gallery 15, and pegs 20, 20, all
substantially as set forth and shown.
Dated this 20th day of February 1897.
