Year: 1865

page_text: LETTERS PATENT to Jean Maublanc, of No. 82, Boulevard Sébastopol,
Paris, in the Empire of France, Lamp Manufacturer, for the Invention
of, "IMPROVEMENTS IN LAMPS FOR BURNING SCHIST, PETROLEUM, AND OTHER
AND THE AND MEANS TO BE EMBLAYED IN LIGHTING FOR CAMP"
Sealed the 23rd March 1866, and dated the 28th September 1865.
PROVISIONAL SPECIFICATION left by the said Jean Maublanc at the
Office of the Commissioners of Patents, with his Petition, on the
28th September 1865.
I, JEAN MAUBLANC, of No. 82, Boulevard Sébastopol, Paris, in the Empire.
of France, Lamp Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LAMPS FOR BURNING SCHIST, PETROLEUM, AND
OTHER SIMILAR OILS, AND IN THE MEANS TO BE EMPLOYED IN LIGHTING. THE SAME,"
to be as follows:-
"
My improved lamp is in form similar to the ordinary lamps for burning
paraffine, with the exception that the bottom of the receiver for containing
the oil is hollow and communicates with a cylindrical canal passing up to the
wick of the lamp. My object in. thus forming the lamp is that it may be
lighted without removing the shade, which is. effected in the following
manner By making use of a small spirit lamp having a neck or socket just
-

page_text: the same length as the cylindrical canal above-mentioned up which it is
passed, and reaching to the wick is readily lighted. This spirit lamp is
enclosed in a metal case, the top being of the same form as the bottom of the
first-mentioned lamp, which it is made to fit, it is mounted on a hollow metal
shaft, round which a spiral spring is placed, one end of which is attached to
the bottom of the case in which the lamp rests and which is moveable, and
the other is fixed to an outer tube in which a pole for reaching to the street
lamp is inserted, on raising the lamp case to the bottom of the former and
gently pressing the pole upwards the lamp is raised from its case and the neck
projecting through a hole made in the top thereof passes up the cylindrical
cavity of the street lamp, and reaching to the wick as already described the
lamp is instantly lighted. This system of constructing lamps may be employed
with great advantage for indoor use as it does not necessitate the removal of
the globe or shade.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Maublanc in the Great Seal Patent Office on the
26th March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
MAUBLANC, of No. 82, Boulevard Sébastopol, Paris, in the Empire of France,
Lamp Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of September, in the year of our.
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year
of Her reign, did, for Herself, Hér heirs and successors, give and grant unto
me, the said Jean Maublanc, Her special licence that I, the said Jean
Maublanc, my executors, administrators, and assigns, or such others as I,
the said Jean Maublanc; my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and' at all tinies
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 "IMPROVE-
MENTS IN LAMPS FOR BURNING SCHIST, PETROLEUM, AND OTHER SIMILAR OILS, AND
IN THE MEANS TO BE EMPLOYED IN LIGHTING THE SAME," upon the condition
(amongst others) that Is the said Jean Maublanc, my executors or adminis-
trators, 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

page_text: 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 Jean Maublanc, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say:-
.The improvements I introduce in the manufacture of lamps have special
reference to those employed for burning volatile oils, such as schist, petroleum,
paraffine, and others, similar thereto, the object of such improvements being
to facilitate the lighting, and this I effect by a peculiar arrangement of con-
struction of the lower and upper parts of the said lamps, and in an apparatus
for lighting the same.
The advantages of my system will be readily understood by, the aid of
the following description, reference being made to the accompanying Drawings,
the same letters of reference indicating like parts where they recur in the
several Figures.
My improved lamp may be made any desired form or dimensions provided
always that the bottom of the receiver for containing the oil is hollow, and
communicates with a cylindrical canal passing up to the wick of the lamp, my
object in thus constructing the lamp being to admit of the insertion of the
lighting apparatus, which consists of a small spirit lamp encased in a metal
cover to protect it from the wind, it is mounted on a pole to reach the lamp,
should such be used for street purposes, or where it cannot be conveniently
reached. The top of the case of the said spirit lamp is made of the same
form and dimensions as the cavity in the bottom of the street lamp, so as to
fit it; the lamp in the interior is provided with a neck of the same length as
the cylindrical cavity of the street lamp, so, that on raising the lighting
apparatus to the lamp by means of the pole, and gently pressing the same
upwards, the spirit lamp which is placed on a moveable bottom attached to a
spiral spring passing round a hollow metal shaft in which the pole is inserted
rises to the top of the metal casing, and the neck of the spirit lamp protuding
through an aperture made in the upper part of the aforesaid casing passes up
the cylindrical cavity of the street lamp, and reaching to the wick thereof, it
is instantly lighted, it will thus be seen that the inconvenience of having to
remove the shade each time of lighting is dispensed with. The wick is
regulated as usual by means of a key or regulator, which may be done with
the aid of the lighting apparatus, an opening being made on the right hand
side of the door of the lantern to allow of the regulator passing through it to
the outside.

improved lamps; Fig. 2 is the lower part of the same; Fig. 3 is a represen-
tation of the same lamp shown on a smaller scale in Fig. 1. A, Figs. 1 and 3,
is the cavity at the bottom of the Jamp; B is the cylindrical canal passing
therefrom to the wick; C is the key or regulator thereof; D, Fig. 1, is the
shade; E, Fig. 2, is the canal up which the spirit lamp is passed, this
Drawing represents the bottom of the lantern; F, Fig. 4, is the lighting
apparatus; G is the spirit lamp; H, H, is the metal casing; I is the hollow
metal shaft, round which the spiral spring is placed; J is the pole inserted
therein.
Havining thus described my Invention, what I claim and desire to secure by
Letters Patent is the peculiar construction of lamp and lighting apparatus
as herein described and illustrated by the accompanying Drawings, at the
same time reserving to myself the right of varying or modyfing the
'form's thereof which can be done without departing from the principle of
construction.
In witness whereof, I, the said Jean Maublanc, have hereunto set my
hand and seal, this Twenty-third day of March, in the year of our
Lord One thousand eight hundred and sixty-six.
Witness,
E. HÉBRÉ,
