PROVISIONAL SPECIFICATION.
Improvements in and connected with Extinguishers for Oil Burning
Lamps.
I FRANCIS THOMAS VINE of Eastington Rectory near Stonehouse in the County
of Gloucester, Clerk in Holy Orders do hereby declare the nature of this invention
to be as follows:-
:―
This invention consists in improvements in and connected with extinguishers for
oil burning lamps.
The improved extinguisher enables one side of a lamp wick tube to be left
entirely free from any mechanism, guide or device connected with the extinguisher
and thus, in duplex lamps allows the space outside each wick, or the space between
the wicks to be left free as aforesaid.
The improved extinguisher is therefore suitable in the last case for use in a lamp
having an auxiliary wick to be used as a night light or for lighting the main wicks
as described in the Specification of my application for Patent No. 1343 dated
24th January 1891.
The improved extinguisher is a plate or bar of approximately the same length
and breadth as the main wick end it is to cover and it is hinged to a frame movable
up and down near the wick tube so that it rests against the side of the wick tube
when lowered and out of action and falls over onto the end of the wick when raised
80 as to extinguish the latter.
The frame aforesaid to which the extinguisher is hinged is connected with a bar
or two bars which are inclined slightly outward at the bottom from the wick tube
and provided with rack teeth so that they may be moved up and down by a toothed
wheel or wheels which may be the same toothed wheels as are used for adjusting-
the wick in the respective tube, there will then be as many bars as there are
wheels acting on the wicks. When the same wheels are used they act upon the
frame or bars and on the wick in reverse directions, lowering the wick when raising
the extinguisher and lowering the extinguisher when raising the wick. A spring"
may be fitted to ensure that the extinguisher shall fall over the end of the wick.
The frames or bars are kept in engagement with the wheels by the usual perforated
cover or guard which may be slightly higher than in ordinary lamps and by a
lower cover through which they also pass.
In lamps in which only one cover can be utilized the frame or bars may be
guided also by passing through a solid metal loop attached to the frame of the
lamp or by a spring pressing the frame or bars against the wheels. The bars
passing through slots in the lower cover which are broader than the thickness of
the bare pass also through shutters or plates just above or below said lower cover,
these shutters having slots just large enough for the bars to pass through so that
the wheels may be disengaged from the bars by this movable shutter which may
be operated to draw the frames or bars from engagement with the teeth of the
wheels. The teeth in the bars are continued far enough only to allow the bars to
be raised sufficiently to allow the extinguishers to fall over the wicks. The
extinguisher cannot thus be raised above this point.

Improvements in and connected with Extinguishers for Oil Burning
Lamps.
I FRANCIS. THOMAS VINE of Eastington Rectory near Stonehouse in the County
of Gloucester, Clerk in Holy Orders 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 consists in improvements in and connected with extinguishers for
oil burning lamps.
The improved extinguisher enables one side of a lamp wick tube to be left
entirely free from any mechanism guide or device connected with the extinguisher
and thus in duplex lamps allows the space outside each wick or the space between
the wicks to be left free as aforesaid.
The improved extinguisher is therefore suitable in the last case for use in a lamp
having an auxiliary wick to be used as a night light or for lighting the main wicks
as described in the Specification of my application for Patent No. 1343 dated
24th January 1891.
The improved extinguisher is a plate or bar of approximately the same length
and breadth as the main wick end it is to cover and it is hinged to a frame movable
up and down near the wick tube so that it rests against the side of the wick tube
when lowered and out of action, and when raised falls over onto the end of the
wick so as to extinguish the latter.
The frame aforesaid to which the extinguisher is hinged is connected with a bar
or two bars which are inclined slightly outward at the bottom from the wick tube
and provided with rack teeth 'so that they may be moved up and down by a toothed
wheel or wheels, which may be the same toothed wheels as are used for adjusting
the wick in the respective tube. There will then be as many bars as there are
wheels acting on the wicks. When the same wheels are used they act upon the
frame or bars and on the wick in reverse directions, lowering the wick when raising
the extinguisher, and lowering the extinguisher when raising the wick. A spring
may be fitted to ensure that the extinguisher shall fall over the end of the wick.
The frames or bars are kept in engagement with the wheels by horizontal shelves
through which they pass, these being attached to the outside of the large wick
tube or by the usual perforated cover or guard which may be slightly higher than
in ordinary lamps and by a lower cover through which they also pass. In lamps
in which only one cover can be utilized the frame or bars may be guided also by
passing through a solid metal loop attached to the frame of the lamp or by a
spring pressing the frame or bars against the wheels. The bars passing through
slots in the lower cover which are broader than the thickness of the bars pass also
through shutters or plates just above or below said lower cover, these shutters
having slots just large enough for the bars to pass through, so that the wheels may
be disengaged from the bars by this movable shutter, which may be operated to
draw the frames or bars from engagement with the teeth of the wheels.
teeth in the bars are continued far enough only to allow the bars to be raised
sufficiently to allow the extinguishers to fall over the wicks. The extinguisher
cannot thus be raised above this point.
Reference being made to the drawings hereto annexed,
Fig. 1 is a vertical central section through the burner of the improved lamp.
Figs. 2 and 3 are similar views showing the parts in different positions.
Fig. 4 is a section on line 4, 4 Fig. 2.
The

page_text: a a are the large wick tubes, b is the frame of the burner c the flame hood,
d the chimney gallery, e the globe gallery f is a small wick tube introduced
between the wick tubes a a and having its lower end f made cylindrical so
that it may slide in the cylindrical socket f10 which is fixed to the main wick
tubes a a.
The cylinder is provided with two helical ribs or screw threads f¹
moving in corresponding female screw threads in the cylindrical socket 10 so that
in lifting the small wick tube f from its lowest position (Fig. 1) to its inter-
mediate position (Fig. 2) it makes a quarter turn to bring the broader cross
width of the tube square to the tubes a a to enable the small wick to catch the
dame from the main wicks, or as the case may be to give the flame to the main
wicks. As the small wick tube f is moved up into its highest position (Fig. 3) it
makes another quarter turn to bring the flame parallel with the slot in the hood c
(Fig. 1). The raising and lowering of the tube f is effected by the lever B
the forward end of which engages in eyes in the ends of the cross bar f' in
the centre of which is the ring which revolves on the cylinder f' between the
collars f. The end of the lever f³ counterbalances the wick tube with
its wick so that the wick tube f maintains its position, as described in the Speci-
fication of Letters Patent No. 1343 of 24 Jany. 1891 beforementioned.
The improved extinguisher for each main wick consists of a plate / adapted to
fall over the end of the wick tube as in Fig. 3 this plate being hinged to the cross
bar forming part with the vertical bars h³ with rack teeth which gear with the
toothed wheels by which the wicks are adjusted in the tubes a a in the known
manner. The spring may be added to ensure that the plate h shall fall onto the
wick tube, when raised. The bars h³ pass through holes in the upper cover j or
through a shelf attached to the main wick tubes and through slots j¹ in the lower
cover of the burner. Above the cover or plate slides for each extinguisher
a guard plate with holes of the exact size to allow the bars h' to pass through.
This guard plate covers the slots j and also serves for carrying the bars h³
into or out of engagement with the wheels h. For this purpose the plate 3 is
formed with a rod t the end of which with the button is made to revolve.
The collar on this part has a piece cut away at 7 so that it may be engaged
with the hook as in Fig. 6 or disengaged as in Fig. 2. In place of this hook
and collar the end 7 may be screw threaded to engage in the fixed nut, or may
be screw threaded to be worked by a rotary nut engaging in a collar fixed to the
lamp burner body. It will be understood that this form of extinguisher may be
used for single wick lamps as well as for duplex burners of any system and that its
use is in no way dependent on the employment of the auxiliary wick. Either
extinguisher may be used independently of the other.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The combination of a wick tube, wheels h³ for adjusting the wick, an extinguisher
consisting of the plate hinged to cross bar h¹ with bar or bars h³ having teeth to
engage with wheels and a sliḍing guard and disengagement plate
purpose set forth.
