IMPROVE- MENTS IN THE MANUFACTURE OR CONSTRUCTION OF LAMPS
Year: 1864

page_text: LETTERS PATENT to George Burt, of No. 33, Lower Temple Street,
Birmingham, in the County of Warwick, for the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OR CONSTRUCTION OF LAMPS."-A communi-
cation from abroad by David Wilson, residing at Colombo, in the Island
of Ceylon.
Sealed the 24th June 1864, and dated the 14th January 1864.
PROVISIONAL SPECIFICATION left by the said George Burt at the
Office of the Commissioners of Patents, with bis Petition, on the 14th
January 1864.
I, GEORGE BURT, of No. 33, Lower Temple Street, Birmingham, in the
County of Warwick, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN THE MANUFACTURE OR CONSTRUCTION OF LAMPS," to be as
follows:-
This Invention has for its object improvements in the manufacture or
construction of lamps for spirit or oil. The reservoir of the lamp, which in
general arrangement is similar to an ordinary solar lamp, is enclosed in a
metal bowl, a small space being left between the exterior of the reservoir and
the interior of the bowl. The upper edge of the bowl is turned inwards and
meets the reservoir which it supports, and small holes are drilled or formed.
around the upper edge of the bowl to permit air to pass freely to the interior
of the flame, sudden drafts being thereby checked. When the lamp thus
arranged is to be employed as a table lamp it is mounted on a pedestal or.

page_text: standard of ornamental glass or china, or it may be of metal or other material.
This pedestal or standard has a bowl at the top, and the reservoir of the lamp
with its exterior bowl drops into it, lugs or pins on the exterior thereof resting
on the rim of the bowl of the pedestal or standard; the metal, with this
exception, is kept out of contact with the pedestal or standard, so that the
latter does not become heated, and when the other parts are removed from
the pedestal or standard this will form a useful and ornamental dish for
containing flowers and fruit, and by a simple addition it becomes an elegant
epergne or candelabra.
When the lamp is to be arranged to hang suspended from a point above it,
in place of using the pedestal or standard before mentioned, the lamp, as
before described, is enclosed between two glass bowls; a perforated metal
ring between the two bowls serves to secure and hold them. The lamp
within is attached by suitable rods to this ring, the rods, chains, or cords,
for hanging the whole are also attached to it, and the air necessary to supply
the flame passes through the perforations before mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Burt in the Great Seal Patent Office on the 14th
July 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BURT, of No. 33, Lower Temple Street, Birmingham, in the County of
Warwick, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,"
the said George Burt, Her special licence that I, the said George Burt, my
executors, administrators, and assigns, or such others as I, the said George
Burt, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OR CONSTRUCTION OF LAMPS," a communication to me from abroad by
David Wilson, a person resident at Colombo, in the Island of Ceylon, upon
the condition (amongst others) that I, the said George Burt, my executors or

page_text: administrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Burt, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object
construction of lamps for spirit or oil.
general arrangement is similar to an
metal bowl, a small space being left between the exterior of the reservoir and
the interior of the bowl. The upper edge of the bowl is turned inwards and
meets the reservoir which it supports, and small holes are drilled or formed
around the upper edge of the bowl to permit air to pass freely to the interior
of the flame, sudden drafts being thereby checked. When the lamp thus
arranged is to be employed as a table lamp it is mounted on a pedestal or
standard of ornamental glass or china, or it may be of metal or other material.
This pedestal or standard has a bowl at the top, and the reservoir of the lamp
with its exterior bowl drops into it, lugs or pins on the exterior thereof resting
on the rim of the bowl of the pedestal or standard, the metal with this
exception is kept out of contact with the pedestal or standard, so that the
latter does not become heated, and when the other parts are removed from
the pedestal or standard this will form a useful and ornamental dish for
containing flowers and fruit, and by a simple addition it becomes an elegant
epergne or candelabra.
improvements in the manufacture or
The reservoir of the lamp, which in
ordinary solar lamp, is enclosed in a
Figure 1 of the annexed Drawing shows a lamp arranged in the manner
above described. a, a, is the reservoir of the lamp; b is a metal bowl enclosing
it, and the upper edge b' of this bowl is turned inwards to meet the reservoir a,
and the two are fitted together. There are small holes formed in the edge b¹
all round for the passage of air through the space between the reservoir a and
the bowl b, and thence to the interior of the flame; c is the pedestal or standard
of the lamp, it is shown partly in section; and d, d, are lugs fixed to the
exterior of the bowl b, they lay in small notches in the edge of the bowl of the
pedestal or standard, which is thus kept out of contact with the other metal
parts of the lamp.
When the lamp is to be arranged to hang suspended from a point above
it, in place of using the pedestal or standard before mentioned, the lamp,

page_text: as before described, is enclosed between two glass bowls; a perforated
metal ring between the two bowls serves to secure and hold them. The
lamp within is attached by suitable rods to this ring, the rods, chains, or
cords for banging the whole are also attached to it, and the air necessary to
supply the flame passes through the perforations before mentioned. Figure 2
of the annexed Drawing shows this arrangement, e, e, are the two glass
bowls, the lower one is shown in section, they are both fitted to the metal
ring f, also shown partly in section; 9, 9, are rods attaching the exterior
bowl 6 of the lamp to the ring f; the bowl b is perforated at bas before;
h, h, are rods, chains, or cords, fixed to the ring f and used for suspending the
lamp.
Figure 3 shows another arrangement of lamp constructed according to this
Invention; it will be seen that by removing the lamp chimney and shade an
epergne may be formed.
In witness whereof, I, the said George Burt, have hereunto set my hand.
and seal, this Eleventh day of July, in the year of our Lord One
thousand eight hundred and sixty-four.
