Abstract
Abstract An improvement in a fluid fossil fuel lantern comprising a lantern chamber, a fuel exit into said chamber and a mantle disposed about said fuel exit which improvement comprises a piezoelectric starting element, the ignition portion of which is disposed in said mantle and supported at least in part by a mantle hanger disposed about said fuel exit and carrying said mantle; an improvement in gas-air lanterns employing a piezoelectric igniter unit wherein the resistance wire of the piezoelectric unit is constructed of an alloy of chromium, aluminum, silicon and iron.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
In a fluid fossil-fuel lantern comprising a lantern chamber, a fuel-air exit into said chamber, a mantle hanger surrounding the fuel exit and a mantle disposed about the fuel exit, the improvement which comprises a piezoelectric starting element having a resistance wire ignition portion, said ignition portion being inserted through the mantle hanger in a region of low pressure, the tip of the resistance wire being positioned in the region of the fuel-air exit into the mantle.
Claim 2
Dependent Claim
77 words
In a fluid fossil-fuel lantern comprising a lantern chamber, a fuel-air exit into said chamber, a mantle hanger surrounding the fuel exit and a mantle disposed about the fuel exit, the improvement which comprises a piezoelectric starting element having a resistance wire ignition portion, said ignition portion being inserted through the mantle hanger in a region of low pressure, the tip of the resistance wire being positioned in the region of the fuel-air exit into the mantle.
Claim 3
Dependent Claim
32 words
An improvement according to claim 1 wherein the resistance wire of the piezoelectric element tapers away from the source of fuel and the fuel comprises a mixture of a hydrocarbon and air.
Claim 4
Dependent Claim
42 words
An improvement according to claim 2 wherein the tip of the piezoelectric element is circular and located 0.100 inch from the screen of the mantle hanger and within a 0.100 inch diameter circle whose center is the center of the mantle hanger.
Claim 5
Dependent Claim
29 words
An improvement according to claim 2 wherein the piezoelectric element is non-rigidly mounted in said mantle hanger and is supported additionally by a bracket disposed above said mantle hanger.
Claim 6
Dependent Claim
32 words
An improvement according to claim 2 wherein the piezoelectric element comprises a resistance wire having a tubular ceramic covering which covering has, at at least one point in its travel, a separation.
Claim 7
Dependent Claim
20 words
An improvement according to claim 2 wherein the mantle hanger contains an exterior coating of an electrolessly deposited nickel plate.
Claim 8
Dependent Claim
25 words
An improvement according to claim 6 wherein the piezoelectric element is held by said mantle hanger and a metal fastener disposed above said mantle hanger.
Claim 9
Dependent Claim
21 words
An improvement according to claim 1 wherein said resistance wire is constructed of an alloy of chromium, aluminum, silicon and iron.
Claim 10
Dependent Claim
19 words
A fluid fossil fuel lantern according to cLaim 8 wherein the alloy has a composition within the following range:
Claim 11
Dependent Claim
45 words
Fluid fossil-fuel lantern comprising a lantern chamber and mantle, a fuel-air exit into said mantle and a piezoelectric starting element having a resistance wire ignition portion, the tip of the resistance wire angularly facing towards said fuel-air exit and then tapering away from said exit.
Claim 12
Dependent Claim
45 words
Fluid fossil-fuel lantern comprising a lantern chamber and mantle, a fuel-air exit into said mantle and a piezoelectric starting element having a resistance wire ignition portion, the tip of the resistance wire angularly facing towards said fuel-air exit and then tapering away from said exit.
