  • Patent number: 4702690
    Abstract: Disclosed is an improved, ultra-compact, piezoelectric spark start, butane fueled, incandescent mantle type lantern for backpackers and the like, which utilizes readily available, common disposable butane cigarette lighters as an insertable and removable "fuel cell". Illumination intensity is operator controlled at the fuel cell flame adjustment control. Piezo sparking is sequenced with push-button movement of the butane lighter gas release lever, for convenient and controlled gas discharge. The lantern base portion is retractable on upright posts, into the globe (upper assembly) once the "fuel cell" is removed from the base guide, and the combination piezoelectric element and fuel cell receiver. Once removed from the receiver integral to the lantern, the "fuel cell" again may be used as a conventional cigarette lighter.
