We, ALFRED HENRY GRIFFITHS, Managing Director, and THOMAS BAKER
SMITH, Manager of Lamp Department, both of Surrey Works, Smethwick,
near Birmingham, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in means for raising the galleries and
globes of what are known as hurricane lamps, or such like lamps.
It consists as follows:-These lamps are usually constructed with a basal oil
container, upon which is carried the burner. From this base two side pillars rise,
which are connected to each other at their upper end, from which extends the
usual turn down handle. Embracing these two sides is a wire like cage or fence,
which fits down tightly thereon. Within this cage or fence is placed the globe or
chimney, which rests upon the gallery, which latter seats itself upon or lies
contiguous to the burner. The said gallery is capable of a rising and falling
movement, such movement being controlled by suitable guides and their comple-
ments upon or attached to the gallery and the upper end of the chimney, and the
frame of the lamp. At the one side of the burner and upon the container or base
are now formed hinged joints to receive the one end of a double sided lifting lever..
This lifting lever is preferably made of wire, which is bent and shaped so that
from such hinged joints aforesaid it shall pass underneath upon each side of the
gallery, and thence is brought together at the front or outer end, so as to form a
lifting handle, which latter, when the gallery is in its lowered position, lies down
closely upon the base so as to be quite out of the way. Upon the underside of
the gallery are provided two channel ways or grooves, in which the two sides of
the lifting lever lie and move which controls and facilitates the lifting movement
of the lever. The outer end or handle of the said lever lying below the rings
constituting the fence, affords also a convenience to the lifting operation, inasmuch
as by grasping the movable handle and the stationary fence between the thumb
and fingers, the lever is readily raised (and with it of course the gallery &c.) to a
Eufficient height for lighting the lamp. The position of the fulcrum of the lever
and its shape are also such that when raised it will retain such raised position until
intentionally lowered.

Hurricane or the like Lamps.
We ALFRED HENRY GRIFFITHS, Managing Director, and THOMAS BAKER
SMITH, Manager of Lamp Department, both of Surrey Works, Smethwick, near
Birmingham, 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 means for raising the galleries and
globes of what are known as hurricane lamps, or-such like lamps.
In order to more clearly explain this our invention we have appended hereunto
illustrative drawings upon which are figures and numbers of reference.
Figs. 1, 2 and 3 show the application of this our invention to a hurricane
lamp.
Figs. 4, 5 and 6, show its application to a modified lamp.
In each case the same reference numbers are used as they indicate in reality the
same characteristic parts in each lamp.
We will first describe the invention as applied to the hurricane lamp as illustrated
in Figs. 1, 2 and 3, in which 8 is the oil container, 9 is the burner, 10, 10, are side
pillars which are connected to each other at their upper end; at which is situated
the usual carrying handle 11. Embracing these two sides is the usual wire like cage
or fence 12 which fits down tightly thereon. Within this cage or fence is placed
the globe or chimney 13, which rests upon the gallery 14, which latter seats itself
upon or lies contiguous to the burner. The said gallery is capable of a rising and
falling movement, such movement being controlled by suitable guides 15, upon or
attached to the gallery 14, working upon the rod 16 attached to the frame or bed
of the lamp. At the one side of the burner and upon the container or base
are now formed hinged joints 17 to receive the one end of a doublesided lifting
lever 18.
This lifting lever is preferably made of wire which is bent and shaped so that
from such hinged joints aforesaid it shall pass underneath upon each side of the
gallery 14, and thence is brought together at the front or outer end see Fig. 1, so
as to form a lifting handle at 19 which latter, when the gallery in its lowered
position as seen in Figs. 1 and 2, lies down closely upon the base so as to be quite
out of the way. Upon the underside of the gallery 14 are provided two channel
ways or grooves 20, 20, in which the two sides of the lifting lever lie and move,
which controls and facilitates the lifting movement of the lever. The outer end
ör handle of the said lever lying below the rings constituting the fence, affords also
a convenience to the lifting operation, inasmuch as by grasping the movable handle
and the stationary fence between the thumb and fingers, the lever is readily raised
(and with it of course the gallery &c.) to a sufficient height for lighting the lamp.
The position of the fulcrum of the lever and its shape are also such that when
raised it will retain such raised position until intentionally lowered, as seen in
Fig. 3.
In Figs. 4, 5 & 6,. the rods 16, rise directly from the base 8, and the gallery 14,
carries the upper portion as before, of the moving parts.
In order to prevent the gallery and its burden being lifted from off the burner.
except as in the manner already described,-such as for instance by an attempt to
carry the whole lamp by means of the gallery or any of its upper parts-we provide
the automatic catch 21, which is pivoted at 22. By gravitation this catch hangs as
seen in Figs. 4 & 5, and the hook part 23, lies beneath the platform plate 24, which
would necessarily check any attempt at rising of the gallery 14, until turned up
out of the way while passing such platform plate.

page_text: Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
The combination with the sliding galleries of lamps such as herein described of
the double sided wire lever 18, pivoted upon the container 8, and operating in the
channels 20, constructed and arranged as described and shown and for the purposes
set forth.
