Improvements in Apparatus for Igniting Illuminating Gas at Burners.
A communication from GUSTAV SKARUPPE, of No. 1, Grimm Strasse, in the City
of Berlin, in the Kingdom of Prussia and German Empire, Manufacturer
of Incandescent Gas Lighting Apparatus.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement; -
The subject of the present invention is a gas lighter consisting of a bent tube
or rod provided at the outer extremity with a hollow ball formed in two parts.
One half of the ball is attached to the tube, the other half being formed as an
open cap adapted to fit on to the first half and be suitably united to it, as for
instance, by a bayonet joint. In the interior of the ball is a removable grid or
sieve having an ignition pilule with platinum wires or threads fastened to it.
By this means the gas is collected in the open cap and ignited by the pilule when
the ball is held over or in the chimney of the burner.
The invention is illustrated by the accompanying drawing on which
Fig. 1 shows a side elevation of the gas lighter partly in section.
Fig. 2 is a section through the ball and sieve.
Fig. 3 is a plan view of the latter.
Figs. 4 and 5 show modified arrangements of the stem for holding the ball.
a is a tube or rod to which is attached a ball bc, consisting of a semi-globular
body and an open cap or cover c. The two parts b c are provided with a
bayonet-joint or like means whereby they may be secured together. Lying loosely
within the ball is a sieve or grid d (see plan view Fig. 3) held in position by
the open cap c.
In the centre of the sieve is an ignition pilule d' of ordinary
manufacture with platinum threads, by means of which the ignition of the gas
is effected.
The tube a may fit into an outer sleeve or socket a¹ secured to the handle A
and be provided with a thumb piece a² (Fig. 1), by means of which it may be
slid outwards for the purpose of lengthening the apparatus. Or the tube a may
be fixed on a solid stem f, as shown in Fig. 4; or it may be secured directly in
the handle A, as shown in Fig. 5.
If desired, an arm or bracket g provided with a key y' may be arranged on
the tube or rod a, opposite to the ball, for the purpose of turning on or off the
gas cock.
Having now particularly described and ascertained the nature of this said in-
vention as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is;-
-
1. A gas lighter comprising a ball or bulbous body, consisting of a hollow rigid
portion and a hollow open lid or cap, secured together by bayonet joint or equi-
valent means and containing a removable grid or sieve provided with an ignition

page_text: pilule and platinum threads, said ball being affixed to a tube or rod secured either
directly, or by means of an intermediate member, to a handle, all substantially
as and for the purpose herein before set forth.
2. A modification of the gas lighter as claimed in Claim 1, wherein the tube
or rod holding the ball passes into a sleeve or socket secured to the handle, in
which socket it may be slid for the purpose of lengthening the apparatus, sub-
stantially as described.
3. A gas lighter as claimed in Claims 1 and 2, wherein a bracket or arm pro-
vided with a key for turning on or off the gas cock is affixed to the tube or rod
opposite to the ball, substantially as described.
Dated this 28th day of October 1899.
