Improvements in Hurricane Lanterns.
1, THOMAS GUY BLOOD, of Neptune Works Great Hampton Street, in the
City of Birminghamh, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to hurricane lanterns or hand lamps of that type in which
air conducting tubes direct heated air from the head to the base aud from thence
to the burner,
The object of my invention is principally to attain accessibility to the burner
for lighting, trimming, and filling the oil chamber and for cleaning the chimney or
globe, and also to reduce the cost of making parts of the said lamps.
My invention thus consists in the one part, in the mounting of the air conducting
tubes so as to admit of the same. swinging backwards; in another part in the
mounting of the hooped clip and guards; in another part, in the making
of the outer shell of the head of the lamp from a single blank of sheet
metal; in another part in combined clips and semi guards for both protecting the
chimney from breakage and keeping the same always full home to its seating
on the gallery, and in a further part, in other detail improvements in' the said
lamps.
A hurricane lamp constructed according to my improvements consists of a
conical base constituting an oil chamber' or tank, having a socket or neck standing
from its top side, to or within which a burner' is fitted, whilst' the wick depends
down an inner tube leading into the tank. The outlets to the air tubes lead into
a chamber in communication with the cone of the burner. The lower parts of the
air tubes are fitted socketwise and turn within or upon sleeves passing through the
neck of the tank, whilst their upper parts' are fixed' and terminate in the head,
the outer shell at which is preferably conical' or hat-shaped, with the crown, body
and Hange of the same made in one piece and from a single blank of sheet metal.
The breaker fitted within the entrance to the head' is pierced with holes where
through heated air passes into the hollow interior and is from' thence conducted
down the air tubes. The movement of the air tubes and head is limited by'a stud
on one of the air tubes taking into the slot of a quadrant-slotted bracket carried
by the base or at the outer termination of one of the' sleeves.
The hoop clip, which grips the top of the chimney and holds the same in an
erect and central position relative to the head, is of a horse shoe shape and
terminates the upper part of a double back' wire to" which horizontal half-ring"
guard wires, whose ends are' made rigid to the air tubes, are 'connected:
The gallery; which is a pierced or grating-like bottom with a central opening
for passing and fitting over and resting upon the cone of a burner, is hinged at its
front or at one side to an upright wire bracket supported from the tank and is
also provided with a handle consisting of a loop of wire throttled into a dumb bell
shape and which is taken hold of for raising the chimney' of the burner.
The chimney or globe, which rests'upon the gallery and' whose upper end' comes
within a short distance of the breaker of the head, is held by a pair of frame-like
spring wire guard-clips, preferably located on the two opposite sides of the same
and with their upper ends made to follow and embrace' the chimney or globe" at'
points above the bulbous lower part. By the force of the springs pressing upon
the inclines of the globe the tendency of the globe is to become self-seating and

page_text: be held firmly upon the gallery. To make the clip arms spring, mouse-trap
springs are formed at the lower parts of the same so as to give the necessary
pressure and resilience.
Assuming the gallery and the head with air tubes to be turned back off the
burner in opposite directions, insert the chimney between the spring clips, when
the same is forced home and held to its seating by the opposite tips of the clips
pressing upon its inclined outer surface.
Then after the lamp has been trimmed and lighted, turn forward the gallery
and globe over the burner and next swing the head and air tube forward, when
the hoop clip is opened out and snaps around the upper part of the chimney.

Improvements in Hurricane Lanterns.
I, THOMAS GUY BLOOD of Neptune Works, Great Hampton Street, in the
City of Birmingham, 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 hurricane lanterns or hand lamps of that type in which
air conducting tubes direct heated air from the head to the base and from thence
to the burner.
The object of my invention is principally to attain accessibility to the burner
for lighting and trimming the wick and filling the oil chamber or tank and for
cleaning the chimney or globe, and also to reduce the cost of making parts of the
said lamps.
My invention thus consists in the one part in the mounting of the air conducting
tubes so as to admit of the same swinging backwards; in another part in the
mounting of the hooped clip and guards; in another part, in the making of the
outer shell of the head or hood of the lamp from a single blank of sheet
metal; in another part, in combined clips and semi guards for both protecting the
chimney from breakage and keeping the same always full home to its seating on
the gallery, and in a further part, in other detail improvements in the said lamps.
A hurricane lamp constructed according to my improvements consists of a
conical base constituting an oil chamber or tank, having a socket or neck standing
from its topside, to or within which a burner is fitted, whilst the wick depends
down an inner tube leading into the tank. The outlets to the air tubes lead into a
chamber in communication with the cone of the burner. The lower parts of the
air tubes, which are each made from a single blank of metal, and have curved
ends, are fitted socketwise and turn within or upon sleeves passing through the
neck of the tank, whilst their upper parts are fixed and terminate in the head or
hood, the outer shell of which is preferably conical or hat-shaped, with the crown,
body, and flange of the same made in one piece and from a single blank of sheet or
cast metal. The breaker fitted within the entrance to the head is pierced with holes
wherethrough heated air passes into the hollow interior and is from thence
conducted down the air tubes. The movement of the air tubes and head may be
limited by a tongue, stud, or equivalent on one of the air tubes taking into the slot
of a quadrant-slotted bracket carried by the base or at the outer termination of
one of the sleeves.
The hoop clip, which grips the top of the chimney and holds the same in an

page_text: erect and central position relative to the head, is of a horse shoe shape and
terminates the upper part of double back wires to which one of the horizontal
half-ring guard wires, whose ends are made rigid to the air tubes, is connected,
whilst the other half guard is hinged on one side to one of the air tubes and is
arranged to swing back.
The gallery, which has a pierced or grating-like bottom with a central opening
for passing and fitting over and resting upon the cone of a burner, is hinged at its
front or at one side to an upright wire bracket supported from the tank.
The chimney or globe, which rests upon the gallery and whose upper end
comes within a short distance of the breaker of the head, is held by a pair of
frame-like spring wire guard clips preferably located on the two opposite sides.
of the same and with their upper ends made to clip and partly follow the
chimney or globe at points above the bulbous lower part. By the force of the
springs pressing upon the inclines of the globe the tendency of the globe is to-
become self seating and be held firmly upon the gallery. To make the clip arms
spring, mouse-trap springs are formed at the lower parts of the same so as to give
the necessary pressure and resilience.
Assuming the gallery and the head with air tubes to be turned back off the
burner in opposite directions, insert the chimney between the spring clips when
the same is forced home and held to its seating by the opposite tips of the clips
pressing upon its inclined outer surface.
Then after the lamp has been trimmed and lighted, turn forward the gallery
and globe over the burner and next swing the head and air tube forward, when
the hoop clips are opened out and suaps around the upper part of the chimney.
Figure 1 of the accompanying drawings represents a back elevation of a
hurricane or hand lantern constructed in accordance with my invention, with the
parts in the positions which they take when the lantern is in use.
Figure 2 represents a vertical section of the lower part of the lantern, with the
gallery and some other accessory parts removed in, order to show the socket joint.
or swinging connection of the air tubes to the base or air chamber part.
Figure 3 represents a side elevation of the lantern with the principal component
parts swung back from over the burner, thus rendering the same accessible for
lighting or trimming the wick or for cleansing purposes.
Figure 4 represents a blank or strip of metal-from which one of the air conducting
tube is made. The ends are corrugated prior to forming the strip into a tube,..
which are subsequently bent into any curved figure as desired. By having the
said ends corrugated they admit of readily being bent into the curved forms shown
in Figure 1.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is the base or oil tank, provided on its topside with a hollow neck or air
chamber a', fitted with the burner b, and an inner tube 61, down which the wick
passes into the oil tank. c are the air tubes, located upon either side of the lamp,
with their upper ends c¹, leading into the hollow head d, through piercings d¹, in
the breaker d, of which, heated air from the body of the lamp passes and is
conducted down the air tubes, whose lower ends c, fit or socket jointwise within or
upon sleeves a², leading into the air chamber below the burner, whereby the said
air tubes admit of swinging from above the burner.
One of the air tubes carries a stud or tongue c³, taking into a quadrant slot c²,
formed in the bracket or plate c, carried on the adjacent sleeve a².
The shell of the head d, is made from a single blank of sheet metal, fashioned
into shape by dies and pressure or by spinning, or by a casting process, whereby
the same remains unaffected by heat and does not come to preces as commonly
occurs in heads made in two or more parts soldered together.
e is the fixed semi-guard with the lower members e¹, made fast to the air-
conducting tubes c, and with the upper members e, formed into spring arms or
clips, which embrace the neck f¹, of the chimney f, which stands upon the

page_text: gallery g, surrounding the burner b and turning upon a joint g, at the summit g³,
of an upright bracket g fixed on the top of the tank a.
Hinged to one of-the-air conducting tubes c, is a second swinging. half guard:h,
carried by sides A', one of which is provided with a catch or fastening h, the other
being hinged at h³, to one of the said air conducting tubes as aforesaid, so that
when the chimney. is required to be turned off. the burner, the guard h;. is swung
back out of the way.
The globe is made self-seating upon the gallery by clips i, spring jointed at,
and with their upper ends i, forcibly pressing upon the inclined sides of the said
chimney above the part of greater diameter, which said sides take the place of
inclined; planes which tend to run back. under the spring clips...
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 :-
First. In hurricane lamps or hand lanterns, swing-jointing the lower ends of the
air-conducting tubes to the base or to the air chamber surmounting the base,
substantially as and for the purpose described and set forth.
Secondly. In hurricane lamps or hand lanterns, the construction of the semi-
guards and chimney clip all carried by swinging air-conducting tubes; substantially
as described and set forth.
Thirdly. In the heads or hoods. of hurricane lamps or hand lanterns, making
the outer shell of the same from a single blank or piece of sheet metal by the
process of stamping or raising or by casting, substantially as described and set
forth.
Fourthly. In hurricane.lamps or hand lanterns, making the chimney self-seating
upon the gallery by spring clips, carried by the said gallery and with their tip
ends impinging. upon the inclined or retreating sides of the said chimney, substan-
tially as described and set forth.
Fifthly. In the air tubes of hurricane lamp; making the same in one piece or
from a single blank, and forming the curved ends in the way and for the purpose
substantially as described and set forth.
Sixthly. The improvements in hurricane lamps or hand lanterns, and in the
general construction, arrangement and combination of the parts of the same,
substantially as and for the purpose described and set forth.
