page_text: Improvements in Hurricane Lamps and Lanterns..
I, EDWARD JOHN SHAW of Astral Works Hatherton Street, Walsall in the
County of Staffordshire, Lamp Manufacturer do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in hurricane lamps and lanterns, more.
particularly in those for which I obtained Letters Patent numbered 2661 and
dated 19th February 1890.
::
In carrying out my invention I construct a spring clasp of wire bent round
into a double horse shoe shape, in such a manner that at the apex or front it has a
width of about an inch between the two bars of the wire, and tapers towards each
end or heel. This clasp which partly encircles the middle of the globe and retains
it in position, being made of one piece bent round into the required form, has a
much greater elasticity, and is less liable to break than if made of two pieces
soldered together at their ends; and also provides a smoother surface at the ends
where in contact with the glass.
The clasp is soldered to the hinged vertical guards and the outer or exposed
surface of the solder where the wires cross, is in each case covered with a small
clip of tin or other suitable material bent round into contact with the two cross
wires, thus rendering the joint stronger and protecting it from injury.
Or in lieu of the above I may arrange for the two wires forming the hinged
vertical guard and supporting the clasp to be carried up close together against the
outer surface of the globe to the height of the clasp.
At this point the wires are bound together by means of a metal clip or wire
soldered thereon; the projecting ends of the wires being bent at right angles or in
a horizontal direction around the neck of the globe to a sufficient extent so as to
grip the same firmly.
I may also construct the guard at the back of the lantern of one wire bent round
so as to form two protecting bars, arranged a suitable distance apart and bulging
into a form similar to that of the globe: One end of the wire is soldered to the
top or hood of the lantern; the wire then passes downwards (keeping to the
contour of the glass) to the bottom where it is hent round and soldered to the top
of the reservoir, then passes up again to the top or hood where the other end is
soldered.
I may also provide a second "grid" or perforated piece of metal, under the
perforated globe carrier so that the cold air in passing to the interior of the globe
must pass through both this second grid and the globe carrier. By this means [ .
effectually "baffle" the wind, and ensure a steady flame under the most adverse
conditions.
With the same object I propose to arrange the air diffuser plate at a short
distance below the level of the wick tube in lieu of at the top as hitherto and I
also form a recess or indentation at either end of the same for the passage of the
air to the burner.
And my improvements further consist in inserting into the interior of the oil
reservoir a cylinder of tin or other suitable material, which cylinder is soldered to
the top and bottom of the reservoir and arranged concentric with it and also
provided with notches or holes at the bottom to permit the access of oil to the

the lantern fall, it lessens the effect of the concussion upon the oil and flame.

improvements in Hurricane Lamps and Lanterns.
I, EDWARD JOHN SHAW of Astral Works, Hatherton Street Walsall in the
County of Staffordshire, 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 improvements in hurricane lamps and lanterns, more
particularly in those for which I obtained Letters Patent numbered 2661 and
dated 19th February 1890; and has for objects to provide in such lamps improved
means for securing in position, and also for protecting, the globe or glass, and
ensuring steadiness of flame and combustion.
I attain these objects by the arrangements and form of construction of the lamps
and lanterns shewn upon the accompanying drawings, upon which :-
Figure is a front elevation of a hurricane lamp fitted with my improvements.
Figure 2 being a back elevation of the same.
Figure 3 shews an alternative construction of globe holder or clasp.
Figure 4 is a modified form of same.
Figure 5, an elevation of the upper portion of the wick tube shewing arrangement
of air-diffusing plate.
Figure 6 a plan of the same.
In carrying out my invention I secure the globe A. or glass part of the lamp,
which may be of ordinary form, in position by means of a spring clasp B constructed
of wire bent round into a double horse-shoe shape, in such a manner that at the
apex or front it has a width of about an inch between the two bars of the wire,
and tapers towards each end or heel, as shewn on Figures 1 and 2. This clasp B
which partly encircles the middle of the globe A and retains it in position, being
made of one piece bent as described, has a much greater elasticity and is less
liable to break in ordinary use than if made in the manner hitherto adopted of two
distinct pieces soldered together at their ends; and ensures also a smoother surface
at the ends where they are in contact with the glass.
The clasp B may be soldered to the hinged vertical guards C, and the outer or
exposed surface of the solder where the crossing wires are joined, may in each case
be covered with a small clip D of tin or other suitable material bent round into
contact with the two cross wires thus rendering the joint stronger and protecting
it from injury.
Or, I may otherwise arrange for the two wires formning the hinged vertical
guard C and supporting the clasp B to be carried up close together against the
outer surface of the globe A to the height of the clasp B. At this point the
wires are bound together by means of a metal clip or wire E soldered thereon;
the projecting ends of the wires being bent at right angles or in a horizontal
direction around the neck of the globe A to a sufficient extent so as to grip the
same firmly, as shewn on Figure 3. Or in lieu of securing the wires of the
vertical guard as above described, I may twist them together at a suitable height,
as at F, and carry the ends horizontally around the globe A sufficiently far to
form a clip, as shewn on Figure 4.
I may also alternatively construct the guard G at the back of the lantern, as in

page_text: Figure 2, of one wire bent round at the bottom so as to form two vertical protecting
bars, arranged at a suitable distance apart and curved to the conformation of the
globe A. One end of the wire is soldered to the top or hood of the lantern and
the wire is thence carried downwards, close to the surface of the glass, to the
bottom where it is bent round and soldered to the top of the reservoir; then it is
carried up again to the top or hood where the other end is soldered.
I may also provide a second "grid or perforated plate of metal H under the
perforated globe carrier, see Figures 1 and 2, so that the air current in passing to
the interior of the globe A must pass through the "grid" or perforated plate H,
as well as the globe-carrier.
By this arrangement the wind is effectually baffled before reaching the wick,
and a steady flame is ensured even under the most adverse conditions.
With the same object I arrange the air diffuser plate K, as shewn on Figure 5,
at a short distance below the level of the wick-tube in lieu of at the top as hitherto ;
and I form a recess or indentation at either end of the plate to allow of the passage
of air to the burner in the desired direction-see Figure 6.
And my improvements further consist in providing within the oil reservoir a
cylinder of tin or other suitable material L, soldered to the top and bottom of the
reservoir concentrically therewith, and furnished with notches or holes at the bottom
to permit access of oil to the wick.
This cylinder L imparts strength to the bottom of the reservoir, and in case
of the lantern accidentally falling, it resists and lessens the effect of, concussion
upon the oil and flame.
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. In hurricane lamps and lanterns, the construction of a spring clasp or globe-
holder B of a single piece of wire partially encircling the glass in the form of a
double-ended loop, and secured to a vertical hinged guard G at the back of
the lantern, as described and illustrated on Figures 1 and 2 of accompanying
drawings.
2. In hurricane lamps and lanterns, the construction as a continuous piece of a
spring globe-holder and vertical hinged guard, consisting of two wires hinged on
the reservoir at their lower ends, twisted together or otherwise joined at the back
of the globe, and extended partially around the same in opposite directions for the
purpose and as described with reference to Figures 3 & 4.
3. In hurricane lamps the arrangement around the wick-tube of an air diffuser
in form of a plate K (Figures 5 and 6) provided with a semi-circular indentation
at either end, in combination with, or without, a second grid or perforated metallic
plate H under the ordinary perforated globe carrier (Figures 1 and 2) as and for
the purposes specified.
4. In hurricane lamps an oil reservoir internally furnished with a metallic
cylinder L soldered or otherwise secured to the top and bottom thereof for the
purpose and as described.
5. Hurricane lamps and lanterns constructed, combined and arranged substantially
as described.
