Improvements in and relating to Lamps, chiefly designed. for
Lighting Public Places, Stations, Lighthouses, and the like...
I, ADOLPHE DESSY, of Gesres, Namur, in the Kingdom of Belgium, Lamp-
maker, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
=
-
My invention relates to lamps chiefly designed for lighting public places,
stations, lighthouses and the like and is illustrated in the accompanying drawing.
The improved lamp constructed according to my said invention comprises
round ball A of crystal or other glass, either solid or hollow. If the ball is
hollow, it must be filled with distilled water. containing a certain quantity of
alcohol in order to be préserved. A shows the thickness of the ball in case it is
made hollow.
Care two parts which extend, all round the ball and which are held together by
a number of bolts F. These two parts are identical in form, the lower part
having its cavity turned upwards and serving as an oil reservoir, while the cavity
of the upper part is turned downward for collecting the smoke which is condensed
therein.
D.shows a number of doors provided with knobs I by which the said doors are
adapted to be opened at will the said doors turning upon two pivots M. These
doors enable the band to be introduced for lighting and extinguishing and for
cleaning the lenses; it is expedient to silver the interior of these doors which will
serve as reflectors.
E are the lenses of hemispherical form having their convex, part, turned towards
the large ball A; the number of leuses employed must be equal to the number
of flames. All these lenses must touch one another and form together an entire
circumference.
Fare bolts for connecting the two parts C and G is the cover for the oil
reservoir and of the smoke box. H shows the flames separated according to the
power of the lenses. Athough separated, all the said flames appear to touch each
other and to form only a single flame extending all round, the large ball A which
consequently presents, the appearance of being completely in, flames.
Jindicates a flat wick burning between the doors D and the plane part of the
lenses E., K shows arms connecting the reservoir with the foot or stand L.
are teeth or serrations which allow the passage of air to form a current through
a slot, this current escaping through holes B. N is the said slot through which the
smoke passes into the smoke box,
O'shows the inner walls of the oil reservoir and smoke box.
As shown at P the door is removed for showing the lenses by the side of the
two doors D.
At Q the door is removed for showing the flames H.

w the outer wall of the reservoir. y the outer wall of the smoke box aud za number
of holes for pouring the oil into the reservoir.
In the bottom of the smoke box are holes B for establishing the air current ;
when these holes are closed the lamp is extinguished. Frost, wind or rain cannot
interfere with the proper operation of this lamp, which may be constructed so as to
be suspended or provided with a foot or stand.

non-explosive and is adapted to burn fat oil. It spreads its light in all directions
and does not in any way injuriously affect the sight. It possesses great advantages
for use in lighthouses, at public places, at railway stations, at the intersection of a
number of streets, in large workshops and the like.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
A lamp chiefly designed for lighting public places, stations, lighthouses and the
like the characteristic feature of which being, a globe A of crystal or glass solid
or hollow, and enclosing if hollow, an uncongealable liquid; a series of lamps H
surrounding the globe in a double envelope C connected by bolts F; lenses E
equal in number to those of the flames and placed between each of these latter
and the globe; doors D silvered on the interior so as to form reflectors; supports Ķ
and a foot L for supporting the whole lamp.
