page_text: JOSEPH BRAHAM 40 Gerrard Street Soho Square W Silversmith 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 that Class of Lamp in which candles are used for
reading or writing purposes."
The Invention consists in being able to read or write by the aid of the same in the
open air so that no draught interfere with the flame of the candle, it depends on
the top and bottom air chambers to keep the candle cool, so that the said candle
may burn and not melt as being in confined space it otherwise would. The
aforesaid Lamp is specially designed for use in India and other hot countries, so as
to withstand the draught caused by the "Punkah" (which is used for cooling or
fanning purposes) which would either blow out the candle, or cause it to flicker so
nuch as to render the Lamp useless, the said Lamp to be named "The open air
reading or writing candle reflector lamp."
Below the top end of the case or stem holding the candle, I forin an air chamber
having holes or openings in its upper surface for the purpose of admitting air to
the interior of the Lamp (for aiding the combustion of the candle) at the top end
of the Lamp I form a hood or covering of any convenient shape, open at its lower
end, and having a hole or opening at its top extremity for carrying off the smoke
&c. beneath the said hood or covering of the chimney of the Lamp I place a tray.
of metal to prevent the draught blowing out or causing the candle to flicker, in the
stem or case in which the candle is inserted is a spring beneath a platform, for the
purpose of keeping the candle to its proper height as in Carriage lamps.
In order that my Invention may be more readily understood and explained in
detail I have hereunto annexed a Sheet of Drawings, on which letters of reference
are marked on corresponding parts on all the Figs. alike.

DESCRIPTION OF DRAWINGS.
Fig. 1. is a front elevation of a Lamp (with the glass door shewn open) having
reflecting surfaces, radiating towards the back end of the said Lamp, this view also
shews the chimey with a conical head or cover through which the smoke &c.
Dasses, and the lower air chamber for air to pass through to keep the candle cool,

Fig. 2 is a side elevation of the Lamp partly in section, (through the line --:
Fig. 1) shewing the reflecting sides radiating towards the back end, the chimney
with the conical head or cover, the tray or ring, the lower air cooling chamber, and
a portion of the spring with platform, for the purposes herein before described.
Fig. 3 is a sectional plan view, through the line zz of Fig. 2 shewing the
openings in the upper surface of the lower air chamber for the admission of air to
keep the candle cold.
In these Figs. a is the conical hood at top of chimney, b the ring or tray for
admission of air, and to protect the candle. from being blown out, c the chimney
d the radiating reflecting sides of the interior of Lamp, e is the lower air chamber
leading to interior of Lamp, f is the stem or case for holding the candle, and
containing the spring and platform g. the base h of the Lamp, may be of any
suitable shape, according to the purpose for which it is required, i is the glass
cover or door with a suitable catch or fastening, and ; are the openings or holes
in the upper surface of the lower air chamber for admission of air to keep the
candle cool.
:
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
.
The construction of a Lamp in which candles are used, having radiating sides
for the purpose of better reflection, the use of a top on the chimneys of such lamps
to protect the light from being blown out, and a lower air chamber, having
openings or holes in its top surface for the purposes as herein substantially
described, set forth and fully illustrated in the drawings annexed.
