Abstract
Abstract A mobile gas lantern in which gas is supplied through a conduit and burner nose to a fragile mantle. A manually actuated piezoelectric igniter system connects to electrodes which extend through the burner nose and establish a spark gap within the mantle to ignite the gas. The ignition system can be used for lighting one or more mantle assemblies simultaneously.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
187 words
A gaseous or vaporized fuel lantern and ignition system therefor, comprising: a substantially bag-like mantle of a fabric which is effective to provide light when in close proximity to a flame, and structural means supporting said mantle; conduit means for supplying a stream of combustible fuel to said mantle, said conduit means including at the terminal end thereof a burner nose having a flame screen provided with a plurality of apertures for letting the fuel pass therethrough exclusively and in direct contact to establish a flame within said mantle, said conduit means having an opening to receive air therethrough to cause mixing of the fuel and the air prior to discharge of the fuel through the flame screen; piezoelectric ignition means effective to generate a voltage upon manual actuation thereof; and electrode means electrically associated with said ignition means and positioned to establish a fixed and stationary spark gap substantially within or proximate to the stream of said fuel and in internal juxtaposition to said bag-like mantle with at least one electrode protruding through said flame screen with its end terminating in close proximity to said screen.
Claim 2
Dependent Claim
187 words
A gaseous or vaporized fuel lantern and ignition system therefor, comprising: a substantially bag-like mantle of a fabric which is effective to provide light when in close proximity to a flame, and structural means supporting said mantle; conduit means for supplying a stream of combustible fuel to said mantle, said conduit means including at the terminal end thereof a burner nose having a flame screen provided with a plurality of apertures for letting the fuel pass therethrough exclusively and in direct contact to establish a flame within said mantle, said conduit means having an opening to receive air therethrough to cause mixing of the fuel and the air prior to discharge of the fuel through the flame screen; piezoelectric ignition means effective to generate a voltage upon manual actuation thereof; and electrode means electrically associated with said ignition means and positioned to establish a fixed and stationary spark gap substantially within or proximate to the stream of said fuel and in internal juxtaposition to said bag-like mantle with at least one electrode protruding through said flame screen with its end terminating in close proximity to said screen.
Claim 3
Dependent Claim
14 words
A lantern according to claim 1, wherein said gap is located within said mantle.
Claim 4
Dependent Claim
13 words
A lantern according to claim 1, wherein said mantle substantially encloses said gap.
Claim 5
Dependent Claim
35 words
A lantern according to claim 1, wherein said mantle is secured to said nose, and said gap is located between one axial end of the burner nose and the opposite axial end of the mantle.
Claim 6
Dependent Claim
17 words
A lantern according to claim 2, wherein the gap is located between said screen and said mantle.
Claim 7
Dependent Claim
36 words
A lantern according to claim 4, wherein said means for carrying fuel includes a conduit connecting to said burner nose; and wherein said electrode means include at least one electrode extending within said fuel carrying conduit.
Claim 8
Dependent Claim
68 words
A lantern according to claim 1, wherein said lantern is composed of a plurality of burners, each having a spark gap connected electrically in series to any other spark gap of the lantern and each said burner being connected to said means for carrying fuel; and wherein a single one of said piezoelectric ignition means is effective to provide a spark substantially simultaneously across all of said gaps.
Claim 9
Dependent Claim
17 words
A lantern according to claim 7, wherein at least one burner includes an electrically conductive burner screen.
Claim 10
Dependent Claim
19 words
A lantern according to claim 7, and in which at least one burner includes an electrically non-conductive burner screen.
Claim 11
Dependent Claim
20 words
A lantern according to claim 8, wherein said electrode means establishes a spark gap jointly with said conductive burner screen.
