PROVISIONAL SPECIFICATION.
An Improvement in the Construction of Hurricane Lanterns.
EDWARD JOHN SHAW Astral Works, Hatherton Street Walsall Glass & Lamp
Manufacturer do hereby declare the nature of this invention to be as follows:
-
The lower edge, of what is called the top or hood of a tin or metal hurricane
lantern, does not come within a quarter of an inch of the globe or glass.
This unprotected space causes the light to be easily blown out.
In my invention the hood comes down about half an inch below, and outside, the
top of the glass, but some quarter of an inch away from the glass all round so that
while the flame is protected from the wind provision is made for the entrance and
exit of air.
I then have to provide for the removal of the globe for lighting.
This I do by cutting part of the 'hood' away, sufficient to let the taper, or top
end of the globe pass through.
To supply this piece of the hood so cut away, I arrange as follows:-
I have two parallel wires, hinged on a cross bar which is fastened to the base of
the lamp.
1 carry these two wires, almost from the base of the lamp, outside the globe and:
up to a little above the top of the globe.
To the top of these wires I attatch a piece of tin sufficient to cover the hole cut in'
the 'hood' for the passing of the globe.
Also, nearly at the top of these two wires, and level with the top of the globe, I
attach a small tin or wire clip which goes over and inside the top edge of the globe
and clips or holds the globe firmly down in its place on the perforated globe-ring
below.
This globe-ring, on which the globe rests, I also hinge on the cross bar at the base.
of the lamp, but seperately from the two wires aforesaid.
The globe-ring is in no way attatched to the two wires.
A horseshoe shaped bow of steel wire keeps the globe in its place.
When my lantern requires lighting I take hold of the two wires with my fingers
and pull towards me.
There then comes towards me, all together, the two wires and the piece attatched to
the top of them for stopping the hole in the front of the hood as well as the globe
ring and the globe.
When lit, I press back the globe and it falls into the horseshoe shaped spring,
carrying with it the wires and the attatched hood piece on their seperate hinges and
the globe ring on its seperate hinge as aforesaid.
I provide a wire guard for preventing the globe from being broken-this is
attatched to the two wires but not to the globe ring.
I may carry my loose hood-piece other than as described-but the novelty of my.
invention is in the hood and in the loose hood-piece,' for admitting the globe, and in
the automatic removal of the loose hood-piece when the globe is removed.

An Improvement in the Construction of Hurricane Lanterns.
I EDWARD JOHN SHAW of Astral Works, Hatherton Street, Walsall, Glass and
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 relates to an improvement in the construction of hurricane lanterns
having for object to better guard the flame of the lamp from being extinguished by
the force of the wind while admitting sufficient air for combustion and permitting the
ready removal of the globe or glass for the purpose of lighting the lamp, and it
consists in the construction of the hood or top of the lantern with a movable piece in
combination with a pivoting globe or glass carrier.
On the accompanying Sheet of Drawing,
Figure 1. represents a side view of a lantern embodying my improvement with
globe or chimney glass shown open, and
Figure 2. is a front view of the same with globe or chimney glass closed.
A being the lamp. B is the hood. Copening formed in same to permit the globe
to pass through. D movable portion or door for covering opening C of hood B.
E wires for carrying movable portion of hood, and glass. El cross-bar upon which
same are hinged. F spring bow within hood to secure globe in position. G clip
to hold globe down on ring. H globe ring. I glass or globe. K wire guard for
globe.
The lower edge of what is called the top or hood of an ordinary tin or metal
hurricane lantern does not come within a quarter of an inch of the globe or
glass.
This unprotected space causes the light to be easily blown out.
It will be seen that in my improved lantern the hood B comes down about half an
inch below, and outside, the top of the glass 1, but at a certain distance, say a quarter
of an inch, away from the glass all round so that while the flame is protected from
the wind, provision is made for the entrance and exit of air.
To provide for the removal of the globe for lighting, part of the hood B is cut
away at C, sufficiently to let the taper, or top end of the globe, pass through.
To supply this piece of the hood so cut away, I arrange as follows:-
:
I have two parallel wires E hinged on a cross-bar E¹ which is fastened to the base
of the lamp A.
I carry these two wires, almost from the base of the lamp, outside the globe and
up to a little above the top of the globe.
To the top of these wires I attach a piece of tin or other metal or material
of sufficient size to cover the hole C cut in the hood for the passage of the
globe.
Nearly at the top of these two wires, and level with the top of the globe, I attach
a small tin or other metal or wire clip G which goes over and inside the top edge of
the globe and clips or holds the globe firmly down into its place on the perforated
globe-ring H below.
This globe-ring H, on which the globe rests, I also hinge on the cross-bar E¹ at
the base of the lamp, but separately from the two wires E, that is to say, this globe-:
ring H is in no way attached to the two wires E.
A horse shoe shaped bow F of steel wire keeps the globe in its place.
When my lantern requires lighting I take hold of the two wires E with my fingers
and pull towards me all together, the two wires E, the door or piece D attached
to the top of them for stopping the hole C, the globe-ring H, and the globe I.
When the lamp is lit I press back the globe I and the wires E pivoting on
the cross-bar El permit the globe to fall into the horse shoe shaped spring F carrying
with it the hood piece or door D together with the globe-ring H on its separate
hinge as aforesaid.

page_text: The wire guard K which prevents the globe from being broken is attached to the
two wires E, but not to the globe-ring H.
I would have it understood that I may vary the means of supporting and pivoting
the globe or glass together with the movable section or door of the hood which may
be of any suitable size and shape and that I may use any suitable metal or material
in the construction of the several parts of my lantern.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A hurricane lantern constructed substantially as hereinbefore described and
illustrated on the accompanying Drawing.
2. In a hurricane lantern a hood having a movable section or door for the
passage of the glass or globe said section being in combination with means of
hingeing or otherwise supporting or carrying the glass or globe and operated thereby
substantially as herein before described.
