Year: 1863

page_text: LETTERS PATENT to Paul Hyacinthe Girardio, of Paris, in the Empire
of France, for the Invention of "IMPROVEMENTS IN LAMPS."
Sealed the 22nd January 1864, and dated the 29th July 1868.
PROVISIONAL SPECIFICATION left by the said Paul Hyacinthe Girardin
at the Office of the Commissioners of Patents, with his Petition,
on the 29th July 1863.
I, PAUL HYACINTHE GIRARDIN, of Paris, in the Empire of France, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LAMPS," to be as follows (that is to say) :—
My Invention has for its object improvements in lamps for burning paraffin
oil, by which greater safety and economy is effected, at the same time ren-
dering the lamp more suitable for burning with straight chimneys than those
at present in use, and consists in the burners being formed with an elongated
oval-shaped passage at the upper portion thereof through which the wick
passes, so as to admit of the said burner being connected with the socket or
holder in one piece without soldering, whereby the escape of gas or vapour is
prevented, as also any danger from explosion or otherwise. The said conical
burner being provided with a gallery in the ordinary manner, and screwed to
the socket upon the stem of the lamp, thereby enabling it to be readily

page_text: removed when required. A flat wick passing into the body of the lamp in
connection with a slot opening in the top or cover of the burner for steading
the light being also employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Paul Hyacinthe Girardin in the Great Seal Patent Office
on the 28th January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL
HYACINTHE GIRARDIN, of Paris, in the Empire of France, send greeting, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date Twenty-ninth day of July, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Paul Ilyacinthe Girardin, Her special licence that I, the said Paul
Hyacinthe Girardin, my executors, administrators, and assigns, or such others
as I, the said Paul Hyacinthe Girardin, 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 LAMPS," upon the condition (amongst others) that I,
the said Paul Hyacinthe Girardin, 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.
NOW KNOW YE, that I, the said Paul Hyacinthe Girardin, do hereby
declare the nature of my said Invention, aud in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement and the Drawings herein referred to (that is to say) :-
My Invention has for its object improvements in lamps for burning paraffine
and other mineral oils, by which great safety and economy is effected, at the
same time rendering the lamp suitable for burning with straight chimneys,
and consists in the burner or beak through which the cotton or wick passes
being made in one piece and without solder, in a conical form, and con-

page_text: necting the said beak or burner to the socket or holder in like manner
without solder, whereby the escape of gas or vapour evolved during the
burning of the same is entirely prevented, as also any danger from explosion
or otherwise, thereby rendering the said parts securer and less subject to get
out of order than those at present in use. The said conical burner being pro-
vided with a gallery or globe bearer in the ordinary manner, and screwed to
the ring upon the stem of the lamp, so as to admit of being readily removed
when required. A flat wick passing through the beak or burner into the body
of the lamp being employed, as also an elliptic-formed hole or slot opening
in the top or cap of the burner in connection therewith for guiding or steadying
the light.
But in order that my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it by aid of the accom-
panying Drawings, reference being had to the letters or figures thereon
marked (that is to say):-
:-
Fig. 1 represents a front elevation of a burner in accordance with my
improvements; Fig. 2, a top or plan view; Fig. 3, an underneath view thereof,
showing the position of the rack for moving the wick; Fig. 4, a transverse
vertical section taken through the dotted line in Fig. 2, as shown; Fig. 5 a
detached plan view of the cap; Fig. 6, side view of the same; and Figs. 7, 8,
& 9, front, side, and sectional views of the conical beak or burner separately
shown.
A, A, ring attached to the stem of the lamp; B, B, conical beak or burner
formed in one piece, through which the flat wick C, C, passes; D, D, toothed
rack for raising or lowering the cotton; E, E, thumb studd for actuating the
same; F, F, screw for securing the burner to the ring; G, G, cap or cover
for euclosing and steadying the light; H, H, opening therein through which
the flame passes; I, I, gallery surrounding the burner; J, J, glass shade;
K, K, straight chimney; L, L, tightening clips formed in the gallery for
holding the same firmly within the gallery by giving or yielding to the chimney
as required; M, M, perforations admitting air to the burner; N, N', clips and
slot fastenings for securing the cap.
Ilaving now fully described and ascertained the nature of this my said
Invention, and the manner in which the same is to be performed and carried
into effect, I would have it clearly understood that I do not intend to confine
myself to the precise details herein-before described, as the same may be
varied without departing from the general principle of these my said improve-
ments; nor do I claim as of my said Invention the exclusive use of the
several parts herein before described, except when the same are employed in

page_text: and for the purposes of my said Invention, which I hereby declare to consist
in forming the beak or burner conically and in one piece without seam or
solder, employing in connection therewith straight chimneys and tightening
clips, in the manner and for the purposes herein-before set forth and described.
In witness whereof, I, the said Paul Hyacinthe Girardin, have here-
unto set my hand and seal, this Twenty-sixth day of January, in the
year of our Lord One thousand eight hundred and sixty-four.
PAUL GIRARDIN. (L.B.)
