Ax IMPROVED REFLECTING APPARATUS FOR STREET AND OTHER LAMPS
Year: 1865

page_text: LETTERS PATENT to Romain de Bray, of Rennes, in the Department of
Ille-et-Vilaine, in the Empire of France, for the Invention of "Ax
IMPROVED REFLECTING APPARATUS FOR STREET AND OTHER LAMPS."
Sealed the 4th August 1865, and dated the 7th February 1865.
PROVISIONAL SPECIFICATION left by the said Romain de Bray at the:
Office of the Commissioners of Patents, with his Petition, on the 7th
February 1865.
I, ROMAIN DE BRAY, of Rennes, in the Department of Ille-et-Vilaine, in
the Empire of France, do hereby declare the nature of the said Invention for
"AN IMPROVED REFLECTING APPARATUS FOR STREET AND OTHER LAMPS," to be as
follows:-
This Invention consists in improved reflecting apparatus for street and
other lamps.
Reflectors varying in number with the shape of the body of the lamp are
placed outside its glazed top; these reflectors may be larger or smaller, and
more or less open, according to the shape of the lamp and the requirements of
the spot to be lighted. The reflectors are formed of two parts, the one
parabolical and the other flat or concave, that is to say, that the parabolical
part is soldered to or of one piece with a plate which covers the glass

page_text: wherever it is not covered by the parabolical reflector; this plate forms also a
flat or concave reflector according to the shape of the glass on which it is
juxtaposited,
The upper glazed part or top of the lamp should be very much sloped to
give greater depth to the reflectors. Each reflector is furnished with hinges,
so that it may be thrown back to be cleaned, and for the cleaning of the glass
which it covers. The effect of the light thrown by these reflectors on the
shadows produced by the lateral ribs of the lamp is to destroy them, but to
attain this result more surely the reflectors may be placed so that their outer
centre comes above the lower ribs. Round lamps lend themselves readily to
this combination.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Romain de Bray in the Great Seal Patent Office on the
5th August 1865,
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROMAIN
DE BRAY, of Rennes, in the Department of Ille-et-Vilaine, in the Empire of
France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of February, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Romain de Bray, Her special licence that I, the said Romain de
Bray, my executors, administrators, and assigns, or such others as I, the
said Romain de Bray, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "AN IMPROVED
REFLECTING APPARATUS FOR STREET AND OTHER LAMPS," upon the condition
(amongst others) that I, the said Romain de Bray, my executors or
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,

page_text: NOW KNOW YE, that I, the said Romain de Bray, do hereby declare
the nature of my 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, reference being had to the accompanying Sheet of Drawing
forming part of this my Specification, and to the diagrams drawn thereon.
Figure 1 shewing the application of my improved apparatus to a round
lamp, the outer centre of the reflectors coming above the lower ribs; Figure 2
its application to a lamp of different shape; and Figure 3, one of my para-
bolical reflectors detached.
The reflectors varying in number with the shape of the body of the lamp
are placed outside its glazed top (see Figures 1 and 2); these reflectors may
be larger or smaller, and more or less open, according to the shape of the
lamp and the requirements of the spot to be lighted. The reflectors are
formed of two parts, the one parabolical and the other flat or concave, that is
to say, that the parabolical part a is soldered to or of one piece with a plate b
which covers the glass wherever it is not covered by the parabolical reflector;
this plate also forms a flat or concave reflector according to the shape of the
glass upon which it is juxtaposited. The upper glazed part or top of the lamp
should be very much sloped to give greater depth to the reflectors. Each
reflector is furnished with hinges c, so that it may be thrown back to be
cleaned, and for the cleaning of the glass which it covers. The effect of the
light thrown by these reflectors on the shadows produced by the lateral ribs ef
the lamp is to destroy them, but to obtain this result more surely the reflectors
may be placed so that their outer centre comes above the lower ribs. Round
lamps lend themselves readily to this combination.
I
In witness whereof, I, the said Romain de Bray, have hereunto set my
hand and seal, this Thirty-first day of July, in the year of our Lord
One thousand eight hundred and sixty-five.
