PROVISIONAL SPECIFICATION.
An Improvement connected with Self-igniting Gas Appliances.
I, JAMES OSBORN SPONG, of 226, High Holborn, London, Domestic Appliances
Manufacturer, do hereby declare the nature of this invention to be as follows:
-
This invention relates to the combination of a slider guard as a protector to
the self-igniting compound and the platinum wire of a pencil like holder by
which when the compound is exposed to the action of flowing gas from a burner
a glow is established sufficient to light the gas.
The guard or protector in skeleton bar, perforated tube, or net like form is
attached to a slider ring or ferrule to be slid up and down on the outside of the
holder, said ring or ferrule may be part of the inner slider or compound carrier,
or the two slider appliances may be so united that they move together.
The article is generally carried in the pocket like an ordinary pencil case and
is always ready for igniting a gas jet by simply drawing the guard and with it
the compound holder to present the compound to the issuing gas jet.
I prefer to use a skeleton bar frame say, of two wires looped and crossing
each other where they may be soldered, brazed, rivetted, or one may be passed
through the other, the ends being secured to a slider ring free to be moved along
a pencil case like appliance and be guided by a slot in the case for direct travel
to and fro, a pin being passed from the slider ring to the plug or slider carry-
ing the compound and platinum wire, so that both move together, or if the
casing be formed with a screw thread, the guard and its connections may have
a rotary forward and backward motion.
It is not essential that the end or ends of the guard be fixed to the slider ring
direct, as it or they may be attached to a ring held between bezels of the slider
ring to have a motion circularwise around the pencil like case.

An Improvement connected with Self-igniting Gas Appliances.
I, JAMES OSBORN SPONG, of 226, High Holborn, London, Domestic Appliances
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:-
This invention relates to the combination of a slider guard as a protector io
the self-igniting compound and the platinum wire of a pencil like holder by
which when the compound is exposed to the action of flowing gas from a burnet
a glow is established sufficient to light the gas.
The guard or protector in skeleton bar, perforated tube, or net like form is
Price Rd

page_text: attached to a slider ring or ferrule to be slid up and down on the outside of the
holder, said ring or ferrule may be part of the inner slider or compound carrier
or the two slider appliances may be so united that they move together.
The article is generally carried in the pocket like an ordinary pencil case and
is always ready for igniting a gas jet by simply drawing the guard and with it
the compound holder to present the compound to the issuing gas jet.
I prefer to use a skeleton bar frame say of two wires looped and crossing
each other where they may be soldered, brazed, rivetted, or one may be passed
through the other, the ends being secured to a slider ring free to be moved along
a pencil case like appliance and be guided by a slot in the case for direct travel
to and fro a pin being passed from the slider ring to the plug or slider carry-
ing the compound and platinum wire so that both move together or if the
casing be formed with a screw thread the guard and its connections may have
a rotary forward and backward motion.
It is not essential that the end or ends of the guard be fixed to the slider ring
direct, as it or they may be attached to a ring held between bezels of the slider
ring to have a motion circularwise around the pencil like case.
The annexed drawings indicate several ways in which my invention can be
carried into effect.
Figure 1 is an elevation of a self igniting gas appliance with the guard a
formed from two wires crossing each other and connected to the slider ring b
for movement up and down the holder e the guard being shown in the open posi-
tion with the igniting compound and platinum wire d exposed ready for ignition
purposes.
Figure 2 is a similar view to Figure 1 but with the guard closed for the appli-
ance to be carried in the pocket.
Figure 3 is a plan of Figure 2. In all the remaining figures the guard is open
with the igniting compound and platinum wire exposed ready for ignition pur-
poses.
Figure 4 is an elevation with the guard a formed of perforated metal.
Figure 5 is an elevation with the guard a formed from woven wire, the wire
being woven to form diamond shaped holes.
Figure 6 is an elevation with the guard a formed from helically wound wire.
Figure 7 is a sectional elevation of a complete appliance in which the guard a
is formed from wire woven with a square mesh, this guard being fitted to the
inner slider or compound carrier e so as to be moved up and down inside the
casing c by the ring f which is connected to the inner slide e by a pin which
moves in the slot c.
Figure 8 is an elevation of a complete appliance, the guard a being fitted to
a separate ring and capable of movement up by action on the ring b which is
loose, the closing movement being effected by action on the ring h.
Figure 9 is an elevation of a complete appliance with a cross wire guard a
as at Figure 1, rings i being arranged as shown and secured in kinks of the
guard a for further protection to the igniting compound and platinum wire. In
this figure the case c is provided with a screw shaped groove g so that a screw
action is given to the ring and guard a when the guard is being opened and
closed.
It will be understood that the drawings only represent a few ways in which
my invention may be carried into effect as the same can be varied as desired
without departing from the spirit of my invention, and in some cases a handle
foldable or not, may be fitted or hinged to the casing c for use when the gas
burner is at a distance away, to be got at easily.
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
1. The improvement connected with self-igniting gas appliances, consisting in

page_text: the combination of a slider guard for protecting the igniting compound and
platinum wire and a pencil-like case or holder, arranged substantially as set
forth.
2. Providing self-igniting gas appliances of the kind described, with an open
worked guard or protector such guard or protector being capable of movement
with the igniting compound and platinum wire when exposed for lighting or
closed for carrying purposes, as described substantially as shown.
