Improvements in Lanterns.
A communication to me from abroad by the firm of GEORGI and BARTSCH, Iron-
mongers, of Breslau, in the Empire of Germany.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent. Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of Middlesex
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 state-
iment and accompanying drawing, (that is to say) :-
This invention. relates to lanterns, and it has for its objects improvements in
apparatus for supplying air to, and for lighting such lanterns.
Lanterns have to meet mauy requirements, for they must burn as brightly and
steadily as possible, without overheating the casing, and they must be capable of being
easily lighted in spite of wind and weather, and the present invention has for its object
improvements by which these requirements are effectually met.
In the accompanying drawing figure 1 is a side view of the said lantern, figure 2 a
vertical section through the same, figure 3 a horizontal section through the saine,
figure a view from below, figures 5, 6, and 7 are two longitudinal sections and a view
from below of the lighting tube upon a larger scale.
At the botton of the casing a space A is formed by the four closed side walls B, the
perforated bottom plate ((figure 4) and by the tinplato D, the latter being placed
parallel to the plate C on a level with the lamp and provided with a central circular
opening E.
The air passes in through holes in the bottom plate C to the space A and from thence
to the free space formed by the lamp F and the central opening E, feeding the flame
and at the same time preventing the overheating of the upper part of the lantern.
Fixed to the blunt corners of the frame supports, are tinbands & with holes d, which
allow the air to enter into the lantern from the sides also, but at the same time force it
to take a circuitous course guided by vertical tinbands e and bent angularly and
forming channels thus breaking the current of air, which serves to cool the lantern and
to feed the flame. Holes G are also formed on the upper part of the walls, for ad-
mitting the outside air for the same purpose.
The lamp F taken by its handle Y can be put in and removed through the door of
the lantern.
By means of two pins M opposite each other and two smail appendages N placed
at right angles to the pins M, all four being soldered to the circular wall of the lamp F
and leaning against the edge of the circular opening E of the plate D, the lamp is fixed
in a central position.
On the edge of the circular opening E in the plate D two small apertures V are cut
out, into which the appendages N of the lamp fit, and a U shaped guide of tin U is
soldered underneath the said edge.
By putting in the lamp F, the appendages N are brought into the apertures V and
by turning the former these appendages are guided by the tinband U until they strike
against its end, and thus fix the lamp in its central position.
The horizontal spindle P for raising and lowering the wick of the lamp F, is long
enough for its disk or handle Q to project outside the lantern. In order to prevent
the wick from slipping down by the oscillations of carriage or the like, and the lamp
from going out, the ribbed disk Q is held tight by a moveable spring.
The lighting apparatus is composed of a tube R (figures 5, 6, and 7) having at the
bottom a trumpet shaped mouth, provided with four small springs S to hold fast an
inserted match, and a tube R¹ somewhat wider than the first, being slipped over it and
having on the top a small knob R³, where a thick wire T is fastened. The latter fits

page_text: into the tube R and when the tubes R and R' are pushed together (figures 2 and 5)
the wire T reaches almost to the springs S.
If a match is now inserted from below into the tube R, the wire T and with it
also the upper tube R' are raised (figure 6) until the movement is stopped by the bent
edges closing on each other, in which position the match is inserted into the tube R
three quarters of its length and held tight by springs S. The match can then be
ignited by striking it on a small roughened or corrugated plate X inside the lantern.
The tubes R and R' that is to say the lighting apparatus rest in the lantern,
being held in place by the top plate V, which is provided with a hole (figures 1. 2)
into which the tube R₁ fits, and further by a hollow double cone W arranged vertically
under the said hole hetween the two bottom plates D and C, holding the underpart of
the tube R, by which means oscillations of the apparatus are prevented. In this
way it is possible to light the candle or the lamp inside the lantern without opening
the door, it being only necessary to insert a match from below into the tube R passing
through the double cone W.
The upper tube R¹ is thus raised up, so that it can be taken hold of and struck on
the plate X.
After lighting the lantern the apparatus is replaced in its former position; by
pressing on the knob R2, the used match is thrust out.
It is obvious that the lantern can as easily be lighted by taking out the whole
lighting apparatus, inserting the match in it, and then returning it to light the lamp.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
1. The space A formed by the perforated bottom-plate, the side walls B and the
tinplate D with its central circular opening E for receiving the lamp, which is held in
its central position by pins M and appendages N, also the free space formed by the
lamp F and the said central opening E, thus admitting the atmospheric air to the
interior of the lantern feeding the flame and at the same time preventing the over-
heating of the metallic parts, substantially as and for the purpose described and shown
in the drawing.
-2. The arrangement of tinbands 6 with holes d upon the blunt corners of the frame
supports and of the guide-tinbands e and forming channels, all for the purpose of
breaking the current of air entering at the side; substantially as described and
shown in the drawing.
3. The lighting apparatus consisting of the tube R (figures 5, 6, and 7) having at
the bottom a trumpet shaped mouth provided with springs S and the tube R' slipped
over the tube R and having at the top a knob R2, where. a thick wire T is fastened,
-the apparatus being placed inside the lantern and held by the top plate V provided
with a hole, and by a hollow double cone W and combined with a roughened plate X
on which the match can be lighted without opening the door, substantially as and for
the purpose described and shown in the drawing.
