Improvements in Hurricane Lanterns.
I, CLEMENT WEST, of 44, Fisher Street, in the City of Birmingham, Lamp
Manufacturer, 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 has relation to hurricane lanterns, and has for its object, to
provide means for permitting of the chimney or globe being easily removed and
replaced, and at the same time prevent the ingress of direct currents of air into
the globe and upper part of the lantern, which is effected by providing the
wind guard or lower skirting of the head with a gap or clearance, closed by a drop-
action slide, door or closure, and through which gap the top end of the chimney
passes (after the slide has been raised) when making an angular movement or
assuming an angular position in being removed from or replaced upon the gallery
or globe holder.
It is also proposed, according to a second part of my invention, to continue
with the guard, a guide or position finder for the chimney when it is being removed
from or introduced into the spring clip.
Figure 1 of the accompanying drawing represents a front elevation of a
hurricane lantern provided with means for facilitating the removal and replace-
ment of the chimney or globe and preventing the ingress of air currents. In this
view the sliding door or closure of the gap in the annular wind guard is shown in
its dropped position.
Figure 2 is a similar elevation to that represented in Figure 1, but showing
the slide raised so as to clear the gap in the front of the windguard to admit of
the removal of the globe or chimney.
Figure 3 is a side elevation of the said lantern, showing the slide raised, and
the globe in the act of being removed.
Figure 4 represents a cross section of the lantern, taken upon the dotted line,
and looking downwards so as to show the other parts of the lamp in plan, and
exemplify the shape or configuration of the improved chimney guard.
Figure 5 represents another section of the lantern, but taken upon the dotted
line, and looking upwards towards the crown of the lamp.
The same letters of reference indicate corresponding parts in the several
figures of the drawings.
a is the base, constituting the usual oil tank, surmounted by the air chamber a¹,
being in communication with the ascending air tubes a², leading to the head, and
fitted with the burner a³ as usual. is the gallery upon which the globe or
chimney c, rests, with the upper or mouth end c, being embraced by a spring
clip d, depending from the head e, into which the ascending air tubes lead, with
a chamber el, at its upper end, and an annular wind guard or skirting e, at the
lower or mouth end, which slightly overhangs or comes below the mouth c¹, at
the top of the chimney c, thereby preventing the ingress of direct air currents
into the interior of the globe and the head of the lantern. This wind guard or
skirting has a gap or clearance 3 to admit of the chimney or globe being intro-

action slide or shutter f, which may be curved and forms a continuation of the
skirting e, and has a tongue or extension f¹, raised by a knob or lift f, working
in vertical guides f2, and coming against a stop f³, at the top of the guides to
prevent the detachment of the closure slide or shutter.
The chimney guard g, which may be carried by the air tubes or any other con-
venient part, is formed into a curved seating or scollop g³, at the front, which
is disposed in such a position relative to the open mouth of the clip as to form a
seating or set for ensuring that the globe, on being placed onto the globe-holder
as represented in Figure 3, shall assume such a position that it will, when turned
in a vertical plane, pass through the mouth of the clip which then closes round
the upper end of the said chimney. It is understood that although scollops are
shown on both sides of the chimney guard, yet this is not necessary, as the
scolloping in the back guard is only formed for the purpose of making, it agree
in shape and appearance with the front one.
Instead of employing only one guard, two or more may be arranged to encircle
the globe at separate points.
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:-
'
First: In hurricane lanterns provided with a head having a gap or clearance
in its lower edge to permit of the removal and introduction of the globe, the
employment of a drop-action or sliding shutter or closure, substantially as
herein described and also as set forth in the accompanying drawings.
Secondly: In hurricane lanterns provided with a head whose lower edge is
gapped to permit of the removal and introduction of the chimney, the employment
of a drop-action or sliding shutter or closure, having a tongue or extension
working within guides on the said head, substantially as herein described, and
also as set forth in the accompanying drawings.
Thirdly: In hurricane lanterns having detachable globes or chimneys, the
employment of a globe set, or globe set and guard combined, substantially as and
for the purpose herein described and also as set forth in the accompanying
drawings.
