AN IMPROVEMENT OR IMPROVEMENTS IN RAILWAY, SHIP, AND CARRIAGE LAMPS
Year: 1853

page_text: LETTERS PATENT to Samuel Messenger, of Birmingham, in the
County of Warwick, Manufacturer, for the Invention of "AN
IMPROVEMENT OR IMPROVEMENTS IN RAILWAY, SHIP, AND CARRIAGE
LAMPS."
Sealed the 18th February 1854, and dated the 15th December 1858.
PROVISIONAL SPECIFICATION left by the said Samuel Messenger
at the Office of the Commissioners of Patents, with his Petition,
on the 15th December 1858.
I, SAMUEL MESSENGER, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT OR IMPROVEMENTS IN RAILWAY, SHIP, AND CARRIAGE
LAMPS to be as follows:-
My said Invention is applicable to those parts of railway, ship, and
carriage lamps which are usually made of plane sheets of metal, and
consists in making the same of corrugated sheets of metal instead of

page_text: the plane sheets ordinarily employed. The cases and other parts of
railway, ship, and carriage lamps are usually weak, from the thinness
and flatness of the metal employed in their construction; this weakness
is sometimes partially remedied by giving the larger surfaces, such as
the sides of the case or body of the lamp, a bulged or convex figure,
but this method of construction only partially remedies the defect, and
is of limited applicability. In order to strengthen the parts of lamps
which are made of sheet metal, I make the same of corrugated sheets
of metal. I make the corrugations in such directions in the several
narts of lamps as are best fitted to give rigidity to the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Messenger in the Great Seal Patent
Office on the 15th June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
SAMUEL MESSENGER, of Birmingham, in the County of Warwick,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of December, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of IIer reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Samuel Messenger, Her special
licence that I, the said Samuel Messenger, my executors, administra-
tors, and assigns, or such others as I, the said Samuel Messenger, 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 "AN
IMPROVEMENT OR IMPROVEMENTS IN RAILWAY, SHIP, AND CARRIAGE LAMPS,"
upon the condition (amongst others) that I, the said Samuel Messenger,
by an instrument in writing under my hand and seal, 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

page_text: 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 Samuel Messenger, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):
My Invention consists in making of corrugated sheets or plates of
metal some of those parts of railway, ship, and carriage lamps, which are
usually made of plain sheets of metal. The cases and other parts of
railway, ship, and carriage-lamps are usually weak and easily bent, from
the thinness and flatness of the metal employed in their construction;
this weakness is sometimes partially remedied by giving the larger sur-
faces, such as the sides of the case or the body of the lamp, a bulged or
convex figure, but this method of strengthening the parts of lamps is of
limited applicability, and is inferior to the method of strengthening the
same by corrugations, which constitutes my Invention. I have repre-
sented in the accompanying Drawing several lamps constructed according
to my Invention, that is to say, having their sides and other parts
strengthened by being made of corrugated plates of metal.
Although in the said Drawing I have represented only the external
parts of lamps made of corrugated plates of metal, and although it is to
such parts that my Invention is particularly applicable, yet my said
Invention may be applied to the burner or such other parts of the
interior of the lamp as require to be strengthened.
In carrying my Invention into effect I make the corrugations in
various directions, as shewn in the accompanying Drawing, the exact
direction or directions given to the said corrugations being determined
by the direction in which strength is most needed in each particular
case.
Having now described the nature of my said Invention, and the
manner of carrying the same into effect, I wish it to be understood that
I do not limit myself to the precise method herein-before described
and illustrated in the accompanying Drawing, as the same may be
varied without departing from the nature of my said Invention; but I
claim as my Invention the application of corrugated plates or sheets of

page_text: metal to the construction of such parts of railway, ship, and carriage
lamps as the same are or may be applicable to.
In witness whereof, I, the said Samuel Messenger, have hereunto
set my hand and seal, this Fourteenth day of June, in the
year of our Lord One thousand eight hundred and fifty-four.
Witness,
RICHARD SKERRETT.
SAMUEL MESSENGER (L.S.)
