Improvement in or connected with the Handles of Umbrellas,
Walking Sticks, Whips, and other Portable Objects.
I, JASPER WETTER, Patent Agent, of 433, Strand, in the City of Westminster
and County of London, 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 :-
This invention has for its object, to provide the handles of walking sticks and
umbrellas, with a simple and convenient igniting apparatus for lighting cigars, or
tobacco pipes and for other purposes.
The igniting apparatus used in this combination is based on the fact, that when
a column of air is rapidly compressed, its temperature rises sufficiently to ignite a
piece of tinder placed in contact with the said air.
In the following description reference will be made to the accompanying
drawing, in which
Fig. 1 is a longitudinal section through the upper part of a walking stick
embodying this invention.
Fig. 2 is a side view of the knob of the walking stick together with the
compressing piston.
Figs. 3 and 4 show on a larger scale the end of the bolt serving to retain the
piston in its normal position.
To attain the object described above, the handle A of the stick is bored out
axially at the upper end, and the inside is lined with a cylindrical tube a of metal
or other suitable material, while the knob C is provided with a compressing
piston B fitted into the tube or lining a.
The compressing piston is preferably made of wood and fixed at the upper end
into the knob C of the stick, while the lower end is hollowed out and fitted with a
piece D of tinder, or other suitable inflammable material. The piston B is nearly
equal in diameter to the bore of the tube a and provided near its lower end with a
suitable packing E to prevent the escape of air upward during the compression.
Near its upper end (close to the knob C) the piston carries a boit F which
passes diametrically through the piston B and is fixed at one end to a spring f
while the other end is rounded or bevelled off in two directions, as shown by
Figs. 3 and 4, in which indicates the cylindrical bore through which passes
the bolt F.
Fig. 3 is a vertical section, and Fig. 4 a horizontal section showing the projecting
end or face of the bolt, which fits into a recess of the tube a and handle A as shown
by Fig. 1.
The rounding of the lower corner (Fig. 3) allows the bolt to enter the tube a
from the top without stopping the piston, when the latter is being forced down, and
the rounding of one side (Fig. 4) causes the bolt to recede out of the hole G, when
the piston is being turned in one direction.
For taking the piston out of the cylinder a, it is sufficient, to turn the knob and
piston from the right to the left and then to pull for closing the stick again, the
piston is slowly introduced into the tube a as far as possible, and then turned
from the left to the right, until the bolt F is opposite the opening G and enters
the same.
For igniting the piece of tinder D, the stick is firmly held with one hand (and
in the case of an umbrella or walking stick, the lower end is made to rest on the

page_text: floor), and with the other hand the piston is rapidly forced down to the bottom and
then rapidly drawn out again, after which the material D will be found burning.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is::
A handle of a walking stick, umbrella, whip or analogous object, adapted to
form a pneumatic fire lighter, substantially as described..
