Improvements in Lanterns.
We, FRANCIS JOSEPH BATEMAN ALLEN and BARUCH CARS both Managing
Directors of Dietz Davis and Company Limited of Lion Lamp Works, Charlotte
Street, Great Eastern Street, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows :--
Our invention relates more particularly to that class of lauterns which are known
as tubular or hurricane lanterns, but it is also applicable to other lanterns in which
a similar kind of globe is employed.
In hurricane lanterns as hitherto constructed difficulty has been experienced in
providing an efficient guard for the globe, which would at the same time admit of
ile globe being readily removed from the burner for lighting, trimming, and
cleaning purposes, and the object of our invention is to obviate these defects.
For this purpose we form one half of the guard a fixture with the lamp body and
we provide at the upper part thereof a spring clip to embrace the neck of the globe
and normally retain it in position upon its support or gallery.
The other half of the globe guard is formed at its upper part with a ring which
embraces the upper part of the globe, and it is similarly formed at its lower part
whilst it is at such point formed with loops through which is passed a horizontal
bar thus constituting a hinge and this bar is provided with legs which removeably
fit corresponding sockets carried by the lamp body.
By these means the globe together with the attached half of the guard may be
turned back upon the hinge to facilitate the lighting or trimming of the lamp, or
the legs may be withdrawn from the sockets and the half guard and globe removed
bodily for the purpose of cleaning the globe or otherwise, the globe turning readily
in its enclosing rings and thus facilitating the cleaning operation.
According to a modified arrangement of parts we fix the legs carrying the hori
zontal bar or an equivalent device to the body of the lamp and we employ a hook
or hooks upon the half guard to engage such bar with capability of being readily
detached and thus constitute a hinge.
According to a further modification we dispense with one of the legs and incline
the other and removeably fit it in a socket fixed to the lamp body and disposed at
an angle corresponding with the leg so that the half guard and globe may be turned
round upon such leg until the burner is exposed and by reason of the inclined
position of the leg and socket the globe and guard will in such movement rise
sufficiently to clear the burner.

Improvements in Lanterns.
We, FRANCIS JOSEPH BATEMAN ALLEN and BARUCH CARS both Managing
Directors of Dietz Davis and Company Limited of Lion Lamp Works Charlotte
Street Great Eastern Street in the County of Middlesex 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:-
Our invention relates more particularly to that class of lanterns which are known
as tubular or hurricane lanterns, but it is also applicable to other lanterns in which
a similar kind of globe is employed.

page_text: In hurricane lanterns as hitherto constructed difficulty has been experienced in
providing an efficient guard for the globe, which would at the same time admit of
the globe being readily removed from the burner for lighting, trimming, and cleaning
purposes, and the object of our invention is to obviate these defects.
For this purpose we form one half of the guard a fixture with the lamp body
and we provide at the upper part thereof a spring clip to embrace the neck of the
globe and normally retain it in position upon its support or gallery.
The other half of the globe guard is formed at its upper part with a ring which
embraces the upper part of the globe and it is similarly formed at its lower part
whilst it is at such point formed with loops through which is passed a horizontal
bar thus constituting a hinge and this bar is provided with legs which removeably
fit corresponding sockets carried by the lamp body.
By these means the globe together with the attached half of the guard may be
turned back upon the hinge to facilitate the lighting or trimming of the lamp or
the legs may be withdrawn from the sockets and the half guard and globe removed
bodily for the purpose of cleaning the globe or otherwise the globe turning readily
in its enclosing rings and facilitating the cleaning operation.
According to a modified arrangement of parts we fix the legs carrying the hori
zontal bar or an equivalent device to the body of the lamp and we employ a hook
or hooks upon the half guard to engage such bar and thus constitute a hinge with
capability of being readily detached.
According to a further modification we dispense with one of the legs and incline
the other and removeably fit it in a socket fixed to the lamp body and disposed at
an angle corresponding with the leg so that the half guard and globe may be turned
round upon such leg until the burner is exposed and by reason of the inclined
position of the leg and socket the globe and guard will in such movement risc
sufficiently to clear the burner.
And in order that the said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a hurricane lantern constructed according to our
invention.
a
Figure 2 is a rear elevation thereof.
Figure 3 is a plan thereof.
Figure 4 is a side elevation of the globe guards and connected parts separately.
Figure 5 is a rear elevation thereof.
Figure 6 is a plan of one of the half guards.
Figure 7 is a plan of the other of the half guards.
Figure 8 is a side elevation of a portion of the globe guards of a lantern illustrating
slight modification.
Figure 9 is a rear elevation thereof.
Figure 10 is a rear elevation of a portion of a lantern illustrating a further
modification and
Figure 11 is a plan thereof.
In the several figures in which like parts are indicated by similar letters of
reference Figures 4 to 9 are drawn full size whilst the other figures are drawn to a
reduced scale.
Referring to Figures 1 to 7 a represents the oil-container or base of the lamp to
which is fixed by its lower part one half of the globe guard whilst the upper part
thereof is by a strap fixed to the cap c.
At the upper part thereof the half guard b is provided with a spring clip 6' to
embrace the neck of the globe d and normally retain it in position upon its
support or gallery a which is carried by the burner a¹ in the ordinary manner.
The other half of the globe guard is formed at its upper part with a ring *1

page_text: which embraces the upper part of the globe d and it is similarly formed at its lower
part with a ring which embraces the lower part of the globe d the natural
spring of the half guard permitting the globe d to be inserted into the required
position as will be readily understood.
At its lower part the half guard is formed with loops b** through which is
passed a horizontal bar &* thus constituting a hinge and this bar ** is provided
with legs 6 which removeably fit corresponding sockets o³ carried by the body or
base a of the lamp.
By these means the globe d together with the attached half of the guard may
be turned back upon the hinge formed by the loops 63 and horizontal bar b** to
facilitate the lighting or trimming of the lamp; or the legs &* may be withdrawn
from the sockets a and the half guard b* together with the globe d removed bodily
for the purpose of cleaning the globe or otherwise when the globe d may
readily be turned within the enclosing rings *** thus facilitating the cleaning
operation.
In the arrangement represented at Figures 8 and 9 the legs b* carrying the
horizontal bar or it might be an equivalent device are fixed, to the body or
base a of the lamp and a broad hook * fixed to the half guard * is employed
which clips on to the bar ** and thus constitutes a hinge but with capability of
being readily detached.
In the arrangement represented at Figures 10 and 11 one of the legs ** and
sockets is dispensed with and the other leg * is inclined or disposed at an
angle to a vertical line whilst the socket a³ upon the base a of the lamp into which
it removeably fits is disposed at a corresponding angle.
By this arrangement of parts the half guard may be turned round upon the
inclined leg which together with socket a³ constitutes a hinge until the burner a¹
is exposed and by reason of the inclined position of the leg and socket a³ the
globe and half guard will in such movement rise sufficiently to clear the
burner a¹.
Although we have shown and described our invention in connection with a
hurricane lantern we would have it understood that it is equally applicable to
other lanterns in which a similar kind of globe is employed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
wwe claim is :-
1. In a lantern fitted with a globe of the character hereinbefore referred to a
globe guard removeably attached and hinged to the lamp body and adapted to
carry a globe substantially as herein shown and described.
2. In a lantern fitted with a globe of the character hereinbefore referred to, the
combination of one half guard fixed to the lamp body and the other half guard
adapted to carry the globe and removeably attached to the lamp body and hinged
for the purpose of exposing the burner for lighting trimming or other purposes
substantially as herein shown and described.
