Improvements in Storm or other Lanterns, Lamps, Stoves,
and the like.
We, JOHN THOMSON PAUL and JAMES PAUL, both of Grove Works, Brand-
field Street, Fountainbridge, Edinburgh, in the County of Midlothian, North
Britain, Lamp and Lantern Manufacturers, 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 storm or other lanterns, lamps, stoves
and the like. The invention is more particularly applicable to storm lanterns, and
has for its object to obtain a very steady flame under all conditions of wind and to
obtain other advantages.
Figure 1 is an elevation of a storm lantern constructed in accordance with our
invention.
Figure 2 is a part sectional elevation of the same and
Figure 3 is a plan of the lower part of the lantern.
Figures 4 to 6 inclusive are details of our said invention.
The lantern consists of a carrying handle A, cowl B, cone C, oil fount D, and
burner E, glass funnel X and glass globe Y protected by a wire guard, as shown.
The necessary air for combustion finds its way to the burner through the
perforations e, in the casing e¹. Inside the said casing is a wind guard e shown
more particularly in Figure 2.
This said Figure shows the top of the burner lifted up by levers in accordance
with a part of our invention hereinafter referred to.
The air ascends up from under the lower edge of the said guard, as shown by the
arrow in Figure 2, fills the space below and around the burner and passes through
the perforated ventilator plate or globe holder e³ as indicated by the arrow Figure 2,
the said plate being shut down upon the top of the casing e when the lamp is in
use a shown in Figure 1. The air ascends through a portion only of the said
ventilator plate e³, that is to say it passes through the holes at the outer edge of the
plate, fills the space between the funnel and the globe, gets heated there and then
descends down through the same plate by means of the inner holes of the plate into
the chamber et formed below the ventilator plate, the air finally escaping through
the perforations of the burner, as indicated by the arrow, up to and around the
flame which burns through the ordinary dome e of the burner. By this arrange-
ment of supplying air steadiness of the flame is ensured as any gusts of air, when
the lamp is used for outside purposes for example, are completely broken by the
aforesaid system of leading the air and a steady flow of air heated by the funnel
being supplied below the burner.
The arrangement for raising the ventilator plate or globe holder e, as shown
more particularly in Figures 2 and 3, consists of levers Foperated by the handle
as hereinafter more particularly described. The top of the lamp when thus raised
and lowered from and to the lower part of the lantern is guided by the rods or
uprights G, the said rods being the means by which the cone with its cowl and
handle is supported from the lower part of the lantern. By the said raising of the
ventilator plate or globe holder, as shown more particularly in Figure 2, the wick
can be quickly and easily lighted and extinguished and trimmed or the burner
cleaned and there is entire safety from explosions when extinguishing the flame.
There is also no liability of the lantern to upset when being lighted or extinguished.
The top of the globe may be provided with a tippet H; so as to retain the heat
between the funnel and the globe.
The globe is protected from breakage by the wire guard which forms another

page_text: part of our said invention. The said guard is constructed of an arrangement of
bent wire as shown in Figure 1 and is such that it can be sprung or expanded over
the globe and taken off in a similar manner, the said guard being thus self-adjusting
and can be readily put on or taken off.
The guard may be constructed as shown in the drawing of a hoop or wire K,
which is jointed at surrounding the circumference of the globe and the legs A
which clasp the side of the globe may also be formed of one length of twisted wire,
being the joint of the wire.
We do not limit ourselves to the said precise mode of constructing the globe
protector as there are various other obvious ways of twisting or bending the wires
to produce the same result, that is to say a wire protector, that is self-adjusting
upon the globe and does not require support or attachment to any part of the lantern.
It will be seen that in accordance with our said invention when the lantern has to
be lit, all that has to be done is to operate the lever when the ventilator plate
carrying with it the burner cap, the funnel and the globe, is raised up clear from
the wick and thus allows the wick to be got at without the slightest trouble.
As shown in Figures 2 and 3 the appliance for elevating the ventilator plate e
consists of the levers F operated by the handle f. The ventilator plate is provided
with two opposite pins against which the levers bear. Owing to the formation of
the arms of the levers and the position of the pins the ventilator plate is always
elevated perfectly vertical as the arms are always bearing at the same vertical line
so that there is no liability of the ventilator plate tending to he tilted from its
vertical travel. The ends of the levers are provided with catches f which act as
checks against the pins f¹ and satisfactorily hold the ventilator in its open position
it being readily seen and felt that when the pins are in the catch portions of
the levers, the ventilator plate is full open. In the plan Fig. 3, the ventilator plate
is not shown and consequently the elevating pins fi are not shown. Also in this
Figure the levers F are shown down.
A further part of our said invention relates to an improved feeder cap for the oil
fount. As shown open in Figure 4, closed in Figure 5, and in section Figure 6, the
cap is made to fit over the neck of the tank aperture without the necessity of any
screw and we employ a peculiar kind of bayonet joint consisting of a pin or pro-
jection j, which takes into the curved recess e, formed in the side of the cap, the
same formation being at opposite sides of the cap as shown in Figure 6, all that is
necessary to do is to press on the feeder cap and at the same time give it a turn
when the mouth of the recess will take on to the projection j and by continuing to
turn the cap it will be forced down tight over the mouth of the feeder owing to the
sloping or curved formation of the recess e, until the projection ; is locked at the
end of the recess, owing to the particular formation of the end of the recess,
the piece of cork or other material with which the underside of the top of the cap
is lined assisting in keeping the cap tight and locked.
The hereinbefore described various arrangements of our said invention may be
altered in many ways without departing from the essential features of our said
invention, for instance the wind guard e may be mounted in various ways so as to
produce the same result, and we might in some cases dispense with the wind
guard.
The same with regard to the chamber e below the ventilator plate; for example
the said chamber might be dispensed with, and air holes made round the burner
above the ventilator plate, admitting air into the burner below the flame.
Also the ventilator plate itself might be made a fixture upon the casing e', and
the elevating levers dispensed with in which case the guide rods or uprights G might
be differently arranged or mounted.
Or the ventilator plate might be made to be raised by hand without elevating
levers; or we might employ any ordinary mechanical device for raising the
ventilator plate.
Or the ventilator might be made to open upon a hinge, or the whole upper part
might be hinged upon the fount.

page_text: Also the ventilator plate might be made without the barner cap fixed to it, that
is to say the burner cap might remain on the burner.
Our said improvements are applicable to all kinds of lanterns lamps or stoves,
and they are also in part applicable to either oil or gas; the wire protector for
example is equally applicable for any globe whether surrounding an oil or gas flame
or other light.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The general arrangement and construction of parts constituting our improve-
ments in lanterns, lamps or stoves, substantially as hereinbefore described and
