PROVISIONAL SPECIFICATION.
Improvements in Bracket Lamps.
I BENJAMIN HALLATT, Old Lenton, Nottingham, Machinist, do hereby declare
the nature of this invention to be as follows:-
-
Each lamp consists of a suitable shaped plain or ornamental plate capable of
being secured to a wall or other surface, from which a bracket projects carrying a
swivelled plug, the top of which is bored out to receive the hollow stem of a circular
or other shaped glass reservoir open at the top, the opening being closed with a
suitable shaped lid or stopper.
From one side of the plug a collared and interiorly screw threaded tube projects,
in which one end of a horizontal tube is firmly screwed the other end of the tube
terminates in a vertical vessel to contain a wick, and the oil or other liquid to be
used for illumination. The top of the vertical vessel terminates in a burner of the
usual construction surrounded with a gallery to support a glass chimney enclosing
the burner.
From the top side of the horizontal tube a vertical tube projects, the upper end
of which is connected to the wick vessel below the gallery, the connection being at
the same height as the top of the glass reservoir. Above the vertical tube one or
more perforated caps are provided which admit air to the lamp wick while burning,
and keeps the top of the lamp cool.

COMPLETE SPECIFICATION.
Improvements in Bracket Lamps!
I BENJAMIN HALLATT, Old Lenton Nottingham Machinist 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 :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view of one of my improved bracket lamps and Figure 2 a
sectional view of the same.
Each lamp consists of the following parts, for each lamp a circular or other
shaped block of wood A is fixed to the wall, to which is secured a suitable shaped
plain or ornamental plate, from which a bracket A' projects having a hole drilled
vertically in its outer end carrying the lower end of a swivelled plug B secured in
position by a screw at its base. The upper part of the plug is bored out and forms
à socket to receive the hollow stem of a globular or other shaped vessel C forming
a reservoir open at the top and closed by a suitable shaped lid or stopper C¹.
The reservoir may be of glass, copper, brass, or other suitable material, when a
glass reservoir is employed the stem is secured in the socket by means of a screw
threaded pin C2 projecting from the bottom of the socket and provided with a slotted
and screw threaded nut C³.
When a reservoir of metal or other suitable material is employed, the stem is
screw threaded to engage with an interior screw threaded socket.
From one side of the plug a collared tube B¹ projects, on which one end of a
horizontal tube B2 is firmly screwed, brazed, or soldered, the other end of the tube

page_text: terminates in a vertical vessel B³ to contain a wick, and the oil or other liquid used
for illumination.
The end of the tube B2 next the vessel B³ is contracted interiorly to form a
narrow passage at the bottom of the tube, through which the whole of the
illuminating liquid runs into the vessel B³.
The top of the vertical vessel terminates in a burner of the usual construction
surrounded with a gallery to support a glass chimney enclosing the burner.
From the top side of the horizontal tube, a tube B₁ projects vertically, the
open outer end of which is connected to the wick vessel B³ below the gallery, the
connection being about the same height as the top of the glass reservoir C,
the tube B is perforated at the top from which a vertical tube projects terminating
in a perforated cap. B' through which air is admitted to the lamp wick while
burning, and keeps the lamp cool.
One side of the wick vessel is slotted and grooved vertically in which a piece of
glass B is cemented to show when a fresh supply of illuminating liquid is
necessary.
The top side of the tube B2 is perforated to receive the lower end of a vertical
tube which terminates in a perforated cap B7, this tube thoroughly ventilates the
tube B2 when the supply of illuminating liquid gets low. Air then rushes through
the tube outwards drawing away any explosive gases from the wick reservoir and
prevents explosion, the light gradually burning out with safety.
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 :-
The improvements in bracket lamps substantially as described and illustrated in
the drawings annexed.
