PROVISIONAL SPECIFICATION.
An Improved Device for containing Volatile and Inflammable
Liquids to be used for Illuminating Purposes.
I, FRANÇOIS HYACINTHE DIFFETOT of Boulevard Henri IV Paris in the
Republic of France, Manufacturer, do hereby declare the nature of this invention
to be as follows :-
The object of this invention is to construct a retainer for holding volatile and
inflammable liquids for the purpose of enabling the same to be used for illuminating
purposes. The said device or retainer forms substantially a torch and consists of
two tubes, one of which fits accurately within the other without leaving any space
between the outer surface of the inner tube and the inner surface of the outer tube;
in the tubes are small holes, those in the inner tube being made so that they may
be arranged to coincide with those in the outer tube. In the inner tube is placed
an absorbent such as sponge, coke, or other suitable material preferably encased in
wire gauze.
The tubes are closed at the ends when in use.
The tubes being filled with the volatile and inflammable liquid, and the liquid
allowed to soak into the absorbent for a sufficient space of time, the torch is ready
for lighting which may be done by applying a light to the lowest hole when the
holes in the two tubes coincide one with another.

COMPLETE SPECIFICATION.
An Improved Device for containing Volatile and Inflammable
Liquids to be used for Illuminating Purposes.
I FRANÇOIS HYACINTHE DIFFETOT of Boulevard Henri IV Paris in the
Republic of France Manufacturer 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 :—
The object of this invention is to construct a retainer for holding volatile and
inflammable liquids for the purpose of enabling the same to be used for illuminating
purposes. The said device or retainer forms, substantially, a torch and consists of
two tubes, one of which fits accurately within the other without leaving any space
between the outer surface of the inner tube and the inner surface of the outer tube;
in the tubes are small holes, that or those in the inner tube being made so that it
or they may be arranged to coincide with that or those in the outer tube. In the
inner tube is placed an absorbent, such as sponge, coke or other suitable
material preferably encased in wire gauze. The tubes are closed at the ends when
in use.
The tubes being filled with the volatile and inflammable liquid, and the liquid
allowed to soak into the absorbent for a sufficient space of time the torch is ready
for lighting which may be done by applying a light to the hole or holes when the
holes in the two tables coincide one with another.
This invention is applicable to any object of a general tubular form, thus as
illustrated in the drawing to a walking stick or a penholder or umbrella. Thus in
applying the invention to a walking stick
Fig. 1 shows the latter as lighted.
Fig. 2 is a tube A of metallic wire gauze containing fragments of sponge, wood

page_text: charcoal and coke B c to be saturated with the illuminant, such as ether, petroleum,
spirit etc. which may be scented.
Fig. 3 is a section of the handle C¹ which may be made to hold matches, with
the tube C in which the tube A is placed.
Fig. 4 shows the outer tube G which forms the walking stick, and is slid over the
inner tube C and fastened by a nose and bayonet slot a b in the socket E of the
handle C¹.
The end of the tube C is closed by a plug F removable, for filling the tube with
the illuminant. T is a hole in the tube C and H is the corresponding orifice in the
tube G this latter orifice being provided with a suitable burner if desired for
instance a "batswing" as in the umbrella in Fig. 6. D is an air admission hole in
the tube C and D₁ is the corresponding hole in the tube G. When the outer
tube G is turned slightly the holes D and D¹ and T and H are brought into
coincidence and the gas or charged air issuing at H may be lighted and will
continue to burn for more or less time according to the capacity of the apparatus.
The hole I which may be in the ferrule or elsewhere is to allow the air to pass
into or from the interior of the stick when the tube C is being withdrawn or
inserted.
Fig. 5 shows a penholder J fitted with the same device and Fig. 6 an umbrella K
so fitted, neither differing in any point from the above description.
Fig. 7 shows a glass or other reflector or guard which may be fastened by a
bayonet joint or otherwise around the burner to steady the flame.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
A device for containing a volatile and inflammable liquid, for illuminating
purposes, consisting of two concentric tubes with holes adapted to be brought into
coincidence the inner tube being filled with an absorbent or absorbents for sai
liquid contained or not contained within a wire gauze holder in said inner tube
substantially as described.
